+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+   Note that it is safe to write "void foo();" indicating a function
+   with no return value, in all K+R compilers we have been able to test.
+
+   For declaring functions with prototypes, we also provide these:
+
+   PARAMS ((prototype))
+   -- for functions which take a fixed number of arguments.  Use this
+   when declaring the function.  When defining the function, write a
+   K+R style argument list.  For example:
+
+	char *strcpy PARAMS ((char *dest, char *source));
+	...
+	char *
+	strcpy (dest, source)
+	     char *dest;
+	     char *source;
+	{ ... }
+
+
+   VPARAMS ((prototype, ...))
+   -- for functions which take a variable number of arguments.  Use
+   PARAMS to declare the function, VPARAMS to define it.  For example:
+
+	int printf PARAMS ((const char *format, ...));
+	...
+	int
+	printf VPARAMS ((const char *format, ...))
+	{
+	   ...
+	}
+
+   For writing functions which take variable numbers of arguments, we
+   also provide the VA_OPEN, VA_CLOSE, and VA_FIXEDARG macros.  These
+   hide the differences between K+R <varargs.h> and C89 <stdarg.h> more
+   thoroughly than the simple VA_START() macro mentioned above.
+
+   VA_OPEN and VA_CLOSE are used *instead of* va_start and va_end.
+   Immediately after VA_OPEN, put a sequence of VA_FIXEDARG calls
+   corresponding to the list of fixed arguments.  Then use va_arg
+   normally to get the variable arguments, or pass your va_list object
+   around.  You do not declare the va_list yourself; VA_OPEN does it
+   for you.
+
+   Here is a complete example:
+
+	int
+	printf VPARAMS ((const char *format, ...))
+	{
+	   int result;
+
+	   VA_OPEN (ap, format);
+	   VA_FIXEDARG (ap, const char *, format);
+
+	   result = vfprintf (stdout, format, ap);
+	   VA_CLOSE (ap);
+
+	   return result;
+	}
+
+
+   You can declare variables either before or after the VA_OPEN,
+   VA_FIXEDARG sequence.  Also, VA_OPEN and VA_CLOSE are the beginning
+   and end of a block.  They must appear at the same nesting level,
+   and any variables declared after VA_OPEN go out of scope at
+   VA_CLOSE.  Unfortunately, with a K+R compiler, that includes the
+   argument list.  You can have multiple instances of VA_OPEN/VA_CLOSE
+   pairs in a single function in case you need to traverse the
+   argument list more than once.
+
+   For ease of writing code which uses GCC extensions but needs to be
+   portable to other compilers, we provide the GCC_VERSION macro that
+   simplifies testing __GNUC__ and __GNUC_MINOR__ together, and various
+   wrappers around __attribute__.  Also, __extension__ will be #defined
+   to nothing if it doesn't work.  See below.
+
+   This header also defines a lot of obsolete macros:
+   CONST, VOLATILE, SIGNED, PROTO, EXFUN, DEFUN, DEFUN_VOID,
+   AND, DOTS, NOARGS.  Don't use them.  */

+/* Summary:
+
+All the apparent functions defined here are macros. The idea
+is that you would use these pre-tested macros to solve a
+very specific set of problems, and they would run fast.
+Caution: no side-effects in arguments please!! They may be
+evaluated MANY times!!
+
+These macros operate a stack of objects.  Each object starts life
+small, and may grow to maturity.  (Consider building a word syllable
+by syllable.)  An object can move while it is growing.  Once it has
+been "finished" it never changes address again.  So the "top of the
+stack" is typically an immature growing object, while the rest of the
+stack is of mature, fixed size and fixed address objects.
+
+These routines grab large chunks of memory, using a function you
+supply, called `obstack_chunk_alloc'.  On occasion, they free chunks,
+by calling `obstack_chunk_free'.  You must define them and declare
+them before using any obstack macros.
+
+Each independent stack is represented by a `struct obstack'.
+Each of the obstack macros expects a pointer to such a structure
+as the first argument.
+
+One motivation for this package is the problem of growing char strings
+in symbol tables.  Unless you are "fascist pig with a read-only mind"
+--Gosper's immortal quote from HAKMEM item 154, out of context--you
+would not like to put any arbitrary upper limit on the length of your
+symbols.
+
+In practice this often means you will build many short symbols and a
+few long symbols.  At the time you are reading a symbol you don't know
+how long it is.  One traditional method is to read a symbol into a
+buffer, realloc()ating the buffer every time you try to read a symbol
+that is longer than the buffer.  This is beaut, but you still will
+want to copy the symbol from the buffer to a more permanent
+symbol-table entry say about half the time.
+
+With obstacks, you can work differently.  Use one obstack for all symbol
+names.  As you read a symbol, grow the name in the obstack gradually.
+When the name is complete, finalize it.  Then, if the symbol exists already,
+free the newly read name.
+
+The way we do this is to take a large chunk, allocating memory from
+low addresses.  When you want to build a symbol in the chunk you just
+add chars above the current "high water mark" in the chunk.  When you
+have finished adding chars, because you got to the end of the symbol,
+you know how long the chars are, and you can create a new object.
+Mostly the chars will not burst over the highest address of the chunk,
+because you would typically expect a chunk to be (say) 100 times as
+long as an average object.
+
+In case that isn't clear, when we have enough chars to make up
+the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+so we just point to it where it lies.  No moving of chars is
+needed and this is the second win: potentially long strings need
+never be explicitly shuffled. Once an object is formed, it does not
+change its address during its lifetime.
+
+When the chars burst over a chunk boundary, we allocate a larger
+chunk, and then copy the partly formed object from the end of the old
+chunk to the beginning of the new larger chunk.  We then carry on
+accreting characters to the end of the object as we normally would.
+
+A special macro is provided to add a single char at a time to a
+growing object.  This allows the use of register variables, which
+break the ordinary 'growth' macro.
+
+Summary:
+	We allocate large chunks.
+	We carve out one object at a time from the current chunk.
+	Once carved, an object never moves.
+	We are free to append data of any size to the currently
+	  growing object.
+	Exactly one object is growing in an obstack at any one time.
+	You can run one obstack per control block.
+	You may have as many control blocks as you dare.
+	Because of the way we do it, you can `unwind' an obstack
+	  back to a previous state. (You may remove objects much
+	  as you would with a stack.)

+/* Character set handling for C-family languages.
+
+   Terminological note: In what follows, "charset" or "character set"
+   will be taken to mean both an abstract set of characters and an
+   encoding for that set.
+
+   The C99 standard discusses two character sets: source and execution.
+   The source character set is used for internal processing in translation
+   phases 1 through 4; the execution character set is used thereafter.
+   Both are required by 5.2.1.2p1 to be multibyte encodings, not wide
+   character encodings (see 3.7.2, 3.7.3 for the standardese meanings
+   of these terms).  Furthermore, the "basic character set" (listed in
+   5.2.1p3) is to be encoded in each with values one byte wide, and is
+   to appear in the initial shift state.
+
+   It is not explicitly mentioned, but there is also a "wide execution
+   character set" used to encode wide character constants and wide
+   string literals; this is supposed to be the result of applying the
+   standard library function mbstowcs() to an equivalent narrow string
+   (6.4.5p5).  However, the behavior of hexadecimal and octal
+   \-escapes is at odds with this; they are supposed to be translated
+   directly to wchar_t values (6.4.4.4p5,6).
+
+   The source character set is not necessarily the character set used
+   to encode physical source files on disk; translation phase 1 converts
+   from whatever that encoding is to the source character set.
+
+   The presence of universal character names in C99 (6.4.3 et seq.)
+   forces the source character set to be isomorphic to ISO 10646,
+   that is, Unicode.  There is no such constraint on the execution
+   character set; note also that the conversion from source to
+   execution character set does not occur for identifiers (5.1.1.2p1#5).
+
+   For convenience of implementation, the source character set's
+   encoding of the basic character set should be identical to the
+   execution character set OF THE HOST SYSTEM's encoding of the basic
+   character set, and it should not be a state-dependent encoding.
+
+   cpplib uses UTF-8 or UTF-EBCDIC for the source character set,
+   depending on whether the host is based on ASCII or EBCDIC (see
+   respectively Unicode section 2.3/ISO10646 Amendment 2, and Unicode
+   Technical Report #16).  With limited exceptions, it relies on the
+   system library's iconv() primitive to do charset conversion
+   (specified in SUSv2).  */
+
+#if !HAVE_ICONV

+/* This is enough to hold any string that fits on a single 80-column
+   line, even if iconv quadruples its size (e.g. conversion from
+   ASCII to UTF-32) rounded up to a power of two.  */
+#define OUTBUF_BLOCK_SIZE 256
+
+/* Conversions between UTF-8 and UTF-16/32 are implemented by custom
+   logic.  This is because a depressing number of systems lack iconv,
+   or have have iconv libraries that do not do these conversions, so
+   we need a fallback implementation for them.  To ensure the fallback
+   doesn't break due to neglect, it is used on all systems.
+
+   UTF-32 encoding is nice and simple: a four-byte binary number,
+   constrained to the range 00000000-7FFFFFFF to avoid questions of
+   signedness.  We do have to cope with big- and little-endian
+   variants.
+
+   UTF-16 encoding uses two-byte binary numbers, again in big- and
+   little-endian variants, for all values in the 00000000-0000FFFF
+   range.  Values in the 00010000-0010FFFF range are encoded as pairs
+   of two-byte numbers, called "surrogate pairs": given a number S in
+   this range, it is mapped to a pair (H, L) as follows:
+
+     H = (S - 0x10000) / 0x400 + 0xD800
+     L = (S - 0x10000) % 0x400 + 0xDC00
+
+   Two-byte values in the D800...DFFF range are ill-formed except as a
+   component of a surrogate pair.  Even if the encoding within a
+   two-byte value is little-endian, the H member of the surrogate pair
+   comes first.
+
+   There is no way to encode values in the 00110000-7FFFFFFF range,
+   which is not currently a problem as there are no assigned code
+   points in that range; however, the author expects that it will
+   eventually become necessary to abandon UTF-16 due to this
+   limitation.  Note also that, because of these pairs, UTF-16 does
+   not meet the requirements of the C standard for a wide character
+   encoding (see 3.7.3 and 6.4.4.4p11).
+
+   UTF-8 encoding looks like this:
+
+   value range	       encoded as
+   00000000-0000007F   0xxxxxxx
+   00000080-000007FF   110xxxxx 10xxxxxx
+   00000800-0000FFFF   1110xxxx 10xxxxxx 10xxxxxx
+   00010000-001FFFFF   11110xxx 10xxxxxx 10xxxxxx 10xxxxxx
+   00200000-03FFFFFF   111110xx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx
+   04000000-7FFFFFFF   1111110x 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx
+
+   Values in the 0000D800 ... 0000DFFF range (surrogates) are invalid,
+   which means that three-byte sequences ED xx yy, with A0 <= xx <= BF,
+   never occur.  Note also that any value that can be encoded by a
+   given row of the table can also be encoded by all successive rows,
+   but this is not done; only the shortest possible encoding for any
+   given value is valid.  For instance, the character 07C0 could be
+   encoded as any of DF 80, E0 9F 80, F0 80 9F 80, F8 80 80 9F 80, or
+   FC 80 80 80 9F 80.  Only the first is valid.
+
+   An implementation note: the transformation from UTF-16 to UTF-8, or
+   vice versa, is easiest done by using UTF-32 as an intermediary.  */

+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',

+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+/* Operator precedence and flags table.
+
+After an operator is returned from the lexer, if it has priority less
+than the operator on the top of the stack, we reduce the stack by one
+operator and repeat the test.  Since equal priorities do not reduce,
+this is naturally right-associative.
+
+We handle left-associative operators by decrementing the priority of
+just-lexed operators by one, but retaining the priority of operators
+already on the stack.
+
+The remaining cases are '(' and ')'.  We handle '(' by skipping the
+reduction phase completely.  ')' is given lower priority than
+everything else, including '(', effectively forcing a reduction of the
+parenthesized expression.  If there is a matching '(', the routine
+reduce() exits immediately.  If the normal exit route sees a ')', then
+there cannot have been a matching '(' and an error message is output.
+
+The parser assumes all shifted operators require a left operand unless
+the flag NO_L_OPERAND is set.  These semantics are automatic; any
+extra semantics need to be handled with operator-specific code.  */

+/*    'off to the right' data being represented as a single digit     */

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files

+  FC          Fortran compiler command
+  FCFLAGS     Fortran compiler flags
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+@chapter Enabling OpenMP
+
+To activate the OpenMP extensions for C/C++ and Fortran, the compile-time 
+flag @command{-fopenmp} must be specified. This enables the OpenMP directive
+@code{#pragma omp} in C/C++ and @code{!$omp} directives in free form, 
+@code{c$omp}, @code{*$omp} and @code{!$omp} directives in fixed form, 
+@code{!$} conditional compilation sentinels in free form and @code{c$},
+@code{*$} and @code{!$} sentinels in fixed form, for Fortran. The flag also
+arranges for automatic linking of the OpenMP runtime library 
+(@ref{Runtime Library Routines}).
+
+A complete description of all OpenMP directives accepted may be found in 
+the @uref{http://www.openmp.org, OpenMP Application Program Interface} manual,
+version 2.5.

+@section Implementing MASTER construct
+
+@smallexample
+if (omp_get_thread_num () == 0)
+  block
+@end smallexample
+
+Alternately, we generate two copies of the parallel subfunction
+and only include this in the version run by the master thread.
+Surely that's not worthwhile though...
+
+
+
+@node Implementing CRITICAL construct
+@section Implementing CRITICAL construct
+
+Without a specified name,
+
+@smallexample
+  void GOMP_critical_start (void);
+  void GOMP_critical_end (void);
+@end smallexample
+
+so that we don't get COPY relocations from libgomp to the main
+application.
+
+With a specified name, use omp_set_lock and omp_unset_lock with
+name being transformed into a variable declared like
+
+@smallexample
+  omp_lock_t gomp_critical_user_<name> __attribute__((common))
+@end smallexample
+
+Ideally the ABI would specify that all zero is a valid unlocked
+state, and so we wouldn't actually need to initialize this at
+startup.
+
+
+
+@node Implementing ATOMIC construct
+@section Implementing ATOMIC construct
+
+The target should implement the @code{__sync} builtins.
+
+Failing that we could add
+
+@smallexample
+  void GOMP_atomic_enter (void)
+  void GOMP_atomic_exit (void)
+@end smallexample
+
+which reuses the regular lock code, but with yet another lock
+object private to the library.
+
+
+
+@node Implementing FLUSH construct
+@section Implementing FLUSH construct
+
+Expands to the @code{__sync_synchronize} builtin.
+
+

+@node Implementing BARRIER construct
+@section Implementing BARRIER construct
+
+@smallexample
+  void GOMP_barrier (void)
+@end smallexample
+
+
+@node Implementing THREADPRIVATE construct
+@section Implementing THREADPRIVATE construct
+
+In _most_ cases we can map this directly to @code{__thread}.  Except
+that OMP allows constructors for C++ objects.  We can either
+refuse to support this (how often is it used?) or we can 
+implement something akin to .ctors.
+
+Even more ideally, this ctor feature is handled by extensions
+to the main pthreads library.  Failing that, we can have a set
+of entry points to register ctor functions to be called.
+
+
+
+@node Implementing PRIVATE clause
+@section Implementing PRIVATE clause
+
+In association with a PARALLEL, or within the lexical extent
+of a PARALLEL block, the variable becomes a local variable in
+the parallel subfunction.
+
+In association with FOR or SECTIONS blocks, create a new
+automatic variable within the current function.  This preserves
+the semantic of new variable creation.
+
+
+
+@node Implementing FIRSTPRIVATE LASTPRIVATE COPYIN and COPYPRIVATE clauses
+@section Implementing FIRSTPRIVATE LASTPRIVATE COPYIN and COPYPRIVATE clauses
+
+Seems simple enough for PARALLEL blocks.  Create a private 
+struct for communicating between parent and subfunction.
+In the parent, copy in values for scalar and "small" structs;
+copy in addresses for others TREE_ADDRESSABLE types.  In the 
+subfunction, copy the value into the local variable.
+
+Not clear at all what to do with bare FOR or SECTION blocks.
+The only thing I can figure is that we do something like
+
+@smallexample
+#pragma omp for firstprivate(x) lastprivate(y)
+for (int i = 0; i < n; ++i)
+  body;
+@end smallexample
+
+which becomes
+
+@smallexample
+@{
+  int x = x, y;
+
+  // for stuff
+
+  if (i == n)
+    y = y;
+@}
+@end smallexample
+
+where the "x=x" and "y=y" assignments actually have different
+uids for the two variables, i.e. not something you could write
+directly in C.  Presumably this only makes sense if the "outer"
+x and y are global variables.
+
+COPYPRIVATE would work the same way, except the structure 
+broadcast would have to happen via SINGLE machinery instead.
+
+
+
+@node Implementing REDUCTION clause
+@section Implementing REDUCTION clause
+
+The private struct mentioned in the previous section should have 
+a pointer to an array of the type of the variable, indexed by the 
+thread's @var{team_id}.  The thread stores its final value into the 
+array, and after the barrier the master thread iterates over the
+array to collect the values.

+@node Implementing PARALLEL construct

+
+@smallexample
+  void GOMP_parallel_start (void (*fn)(void *), void *data, unsigned num_threads)
+@end smallexample
+
+The @var{FN} argument is the subfunction to be run in parallel.
+
+The @var{DATA} argument is a pointer to a structure used to 
+communicate data in and out of the subfunction, as discussed
+above with respect to FIRSTPRIVATE et al.
+
+The @var{NUM_THREADS} argument is 1 if an IF clause is present
+and false, or the value of the NUM_THREADS clause, if
+present, or 0.
+
+The function needs to create the appropriate number of
+threads and/or launch them from the dock.  It needs to
+create the team structure and assign team ids.
+

+      @} while (GOMP_loop_runtime_next (&_s0, _&e0));
+    GOMP_loop_end ();
+  @}
+@end smallexample
+
+Note that while it looks like there is trickyness to propagating
+a non-constant STEP, there isn't really.  We're explicitly allowed
+to evaluate it as many times as we want, and any variables involved
+should automatically be handled as PRIVATE or SHARED like any other
+variables.  So the expression should remain evaluable in the 
+subfunction.  We can also pull it into a local variable if we like,
+but since its supposed to remain unchanged, we can also not if we like.
+
+If we have SCHEDULE(STATIC), and no ORDERED, then we ought to be
+able to get away with no work-sharing context at all, since we can
+simply perform the arithmetic directly in each thread to divide up
+the iterations.  Which would mean that we wouldn't need to call any
+of these routines.
+
+There are separate routines for handling loops with an ORDERED
+clause.  Bookkeeping for that is non-trivial...

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+	* Makefile.in:  Re-did how EXTRA_OFILES is used to be more useful.
+	* README:  Explained how the auto-configuration works,
+	and how to add new files and/or configurations.
+
+Fri Nov 22 09:45:23 1991  John Gilmore  (gnu at cygnus.com)
+
+	* strtoul.c:  Avoid defining ULONG_MAX if already defined;
+	cast a const char * to char * for pedants.
+
+	* getopt.c:  Only define "const" after local include files get to,
+	and only if they haven't defined it.
+
+Thu Nov 21 16:58:53 1991  John Gilmore  (gnu at cygnus.com)
+
+	* getcwd.c (remove getwd.c): GNU code should call getcwd().  We
+	emulate it with getwd() if available.  This avoids callers having
+	to find a MAXPATHLEN or PATH_MAX value from somewhere.
+	* Makefile.in, functions.def:  getwd->getcwd.
+	* configure.in:  Use generic case for every system.
+	* config/mh-{delta88,mach,rs6000,svr4}:  Remove.
+	* config/mh-sysv:  Use default handling, just add -DUSG.
+
+Thu Nov 14 10:58:05 1991  Per Bothner  (bothner at cygnus.com)
+
+	* Makefile.in, config/mh-default: Re-do make magic
+	so that for the default ("automatic") mode we only
+	compile the files we actually need.  Do this using
+	a recursive make:  The top-level generates the list
+	of needed files (loosely, the ones missing in libc),
+	and then passes that list to the recursive make.
+	* config/mh-mach:  Remove obsolete STRERROR-{C,O} macros.
+
+Tue Nov 12 19:10:57 1991  John Gilmore  (gnu at cygnus.com)
+
+	RS/6000 host support (grumble).
+
+	* configure.in:  Build alloca-conf.h file from alloca-norm.h
+	(everything else) or alloca-botch.h (rs/6000).
+	* Makefile.in:  Include . on the include path.
+	* getopt.c:  Use alloca-conf.h.
+	* alloca-norm.h:  How to declare alloca on reasonable machines.
+	* alloca-botch.h: How to declare alloca on braindead machines.
+
+Tue Nov 12 09:21:48 1991  Fred Fish  (fnf at cygnus.com)
+
+	* concat.c :  New file, like concat() in gdb but can take a
+	variable number of arguments rather than fixed at 3 args.  For
+	now, client applications must supply an xmalloc(), which is a
+	front end function to malloc() that deals with out-of-memory
+	conditions.
+
+	* Makefile.in:  Add concat.c and concat.o to appropriate macros.
+
+Sat Nov  9 13:29:59 1991  Fred Fish  (fnf at cygnus.com)
+
+	* config/mh-svr4:  Add sigsetmask to list of required functions.
+
+Sun Nov  3 11:57:56 1991  Per Bothner  (bothner at cygnus.com)
+
+	* vsprintf.c:  New file.
+	* functions.def, Makefile.in:  Add vsprintf.
+
+Sun Oct 27 16:31:22 1991  John Gilmore  (gnu at cygnus.com)
+
+	* configure.in, config/mh-rs6000:  Add rs/6000 host support.
+	* Makefile.in:  Compile with debug info.
+
+Fri Oct 25 17:01:12 1991  Per Bothner  (bothner at cygnus.com)
+
+	* Makefile.in, configure.in, and new files: dummy.c, functions.def,
+	config/mf-default:  Added a default configuration mode,
+	which includes into libiberty.a functions that are "missing" in libc.
+	* strdup.c, vprintf.c, vfprintf.c: New files.
+
+Thu Oct 24 02:29:26 1991  Fred Fish  (fnf at cygnus.com)
+
+	* config/hmake-svr4: New file.
+
+	* config/hmake-sysv: Add HOST_CFILES and HOST_OFILES.
+
+	* basename.c, bcmp.c, bcopy.c, bzero.c, getpagesize.c getwd.c,
+	index.c, insque.c, rindex.c, spaces.c, strstr.c, vfork.c: New
+	files containing either portable C versions or emulations using
+	native library calls.
+
+	* strerror.c:  Add copyright, internal documentation, etc.
+
+	* strtol.c:  Replace hardwired hex constants with some more
+	portable macros.  Remove illegal (according to gcc) cast.
+
+	* strtoul.c: Replace hardwired hex constant with more portable
+	macro.
+
+	* Makefile.in: Move TARGETLIB and CFLAGS where makefile fragments
+	can override them.  Add new source and object file names to CFILES
+	and OFILES respectively.
+
+	* configure.in: Add support for SVR4 makefile fragments.
+
+Tue Oct 22 19:00:23 1991  Steve Chamberlain  (steve at cygnus.com)
+
+	* Makefile.in: Move RANLIB, AR and AR_FLAGS to where they can be
+	over-ridden by config/hmake-*
+	* configure.in: added m88kcvs to sysv list
+
+Fri Oct  4 01:29:08 1991  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.in:  Most hosts need strerror, but one or two don't,
+	and they override these definitions in the host-dependent makefile
+	fragment.
+	* config/hmake-mach:  The odd man out on strerror -- it's supplied.
+	* strerror.c:  New file.
+
+	* strtol.c, strtoul.c:  Add strtol to libiberty, since Mach lacks
+	it and bfd uses it.
+	* configure.in, Makefile.in, config/hmake-mach:  Only configure
+	strtol & strotoul in on Mach.
+
+Tue Sep  3 06:36:23 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* obstack.c:  Merge with latest FSF version.

+This directory contains the -liberty library of free software.
+It is a collection of subroutines used by various GNU programs.
+Current members include:
+
+	getopt -- get options from command line
+	obstack -- stacks of arbitrarily-sized objects
+	strerror -- error message strings corresponding to errno
+	strtol -- string-to-long conversion
+	strtoul -- string-to-unsigned-long conversion
+
+We expect many of the GNU subroutines that are floating around to
+eventually arrive here.
+
+The library must be configured from the top source directory.  Don't
+try to run configure in this directory.  Follow the configuration
+instructions in ../README.
+
+Please report bugs to "gcc-bugs@gcc.gnu.org" and send fixes to
+"gcc-patches@gcc.gnu.org".  Thank you.
+
+ADDING A NEW FILE
+=================
+
+There are two sets of files:  Those that are "required" will be
+included in the library for all configurations, while those
+that are "optional" will be included in the library only if "needed."
+
+To add a new required file, edit Makefile to add the source file
+name to CFILES and the object file to REQUIRED_OFILES.
+
+To add a new optional file, it must provide a single function, and the
+name of the function must be the same as the name of the file.
+
+    * Add the source file name to CFILES.
+
+    * Add the function to name to the funcs shell variable in
+      configure.ac.
+
+    * Add the function to the AC_CHECK_FUNCS lists just after the
+      setting of the funcs shell variable.  These AC_CHECK_FUNCS calls
+      are never executed; they are there to make autoheader work
+      better.
+
+    * Consider the special cases of building libiberty; as of this
+      writing, the special cases are newlib and VxWorks.  If a
+      particular special case provides the function, you do not need
+      to do anything.  If it does not provide the function, add the
+      object file to LIBOBJS, and add the function name to the case
+      controlling whether to define HAVE_func.
+
+The optional file you've added (e.g. getcwd.c) should compile and work
+on all hosts where it is needed.  It does not have to work or even
+compile on hosts where it is not needed.
+
+ADDING A NEW CONFIGURATION
+==========================
+
+On most hosts you should be able to use the scheme for automatically
+figuring out which files are needed.  In that case, you probably
+don't need a special Makefile stub for that configuration.
+
+If the fully automatic scheme doesn't work, you may be able to get
+by with defining EXTRA_OFILES in your Makefile stub.  This is
+a list of object file names that should be treated as required
+for this configuration - they will be included in libiberty.a,
+regardless of whatever might be in the C library.

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */
+
+/*
+
+@deftypefn Replacement void* alloca (size_t @var{size})
+
+This function allocates memory which will be automatically reclaimed
+after the procedure exits.  The @libib{} implementation does not free
+the memory immediately but will do so eventually during subsequent
+calls to this function.  Memory is allocated using @code{xmalloc} under
+normal circumstances.
+
+The header file @file{alloca-conf.h} can be used in conjunction with the
+GNU Autoconf test @code{AC_FUNC_ALLOCA} to test for and properly make
+available this function.  The @code{AC_FUNC_ALLOCA} test requires that
+client code use a block of preprocessor code to be safe (see the Autoconf
+manual for more); this header incorporates that logic and more, including
+the possibility of a GCC built-in function.

+string.  This ensures that we always have enough space in which to
+work, since the extracted arg is never larger than the input string.

+
+Concatenate zero or more of strings and return the result in freshly
+@code{xmalloc}ed memory.  Returns @code{NULL} if insufficient memory is
+available.  The argument list is terminated by the first @code{NULL}
+pointer encountered.  Pointers to empty strings are ignored.

+
+NOTES
+
+	This function uses xmalloc() which is expected to be a front end
+	function to malloc() that deals with low memory situations.  In
+	typical use, if malloc() returns NULL then xmalloc() diverts to an
+	error handler routine which never returns, and thus xmalloc will
+	never return a NULL pointer.  If the client application wishes to
+	deal with low memory situations itself, it should supply an xmalloc
+	that just directly invokes malloc and blindly returns whatever
+	malloc returns.

+   Here is a matrix of mmap possibilities:
+	mmap private not fixed
+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+as the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+@end display
+
+@appendixsubsec Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software---to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software---typically libraries---of the Free
+Software Foundation and other authors who decide to use it.  You can use
+it too, but we suggest you first think carefully about whether this
+license or the ordinary General Public License is the better strategy to
+use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of it
+in new free programs; and that you are informed that you can do these
+things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the @dfn{Lesser} General Public License because it
+does @emph{Less} to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+``work based on the library'' and a ``work that uses the library''.  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.

+@center GNU LESSER GENERAL PUBLIC LICENSE
+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end ifinfo
+
+@enumerate 0
+@item
+This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this
+Lesser General Public License (also called ``this License'').  Each
+licensee is addressed as ``you''.
+
+  A ``library'' means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The ``Library'', below, refers to any such software library or work
+which has been distributed under these terms.  A ``work based on the
+Library'' means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term ``modification''.)
+
+  ``Source code'' for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+@item
+You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+@item
+You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+The modified work must itself be a software library.
+
+@item
+You must cause the files modified to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause the whole of the work to be licensed at no
+charge to all third parties under the terms of this License.
+
+@item
+If a facility in the modified Library refers to a function or a
+table of data to be supplied by an application program that uses
+the facility, other than as an argument passed when the facility
+is invoked, then you must make a good faith effort to ensure that,
+in the event an application does not supply such function or
+table, the facility still operates, and performs whatever part of
+its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has
+a purpose that is entirely well-defined independent of the
+application.  Therefore, Subsection 2d requires that any
+application-supplied function or table used by this function must
+be optional: if the application does not supply it, the square
+root function must still compute square roots.)
+@end enumerate
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+@item
+You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a ``work that uses the Library''.  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a ``work that uses the Library'' with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a ``work that uses the
+library''.  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a ``work that uses the Library'' uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+@item
+As an exception to the Sections above, you may also combine or
+link a ``work that uses the Library'' with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+@enumerate a
+@item
+Accompany the work with the complete corresponding
+machine-readable source code for the Library including whatever
+changes were used in the work (which must be distributed under
+Sections 1 and 2 above); and, if the work is an executable linked
+with the Library, with the complete machine-readable ``work that
+uses the Library'', as object code and/or source code, so that the
+user can modify the Library and then relink to produce a modified
+executable containing the modified Library.  (It is understood
+that the user who changes the contents of definitions files in the
+Library will not necessarily be able to recompile the application
+to use the modified definitions.)
+
+@item
+Use a suitable shared library mechanism for linking with the Library.  A
+suitable mechanism is one that (1) uses at run time a copy of the
+library already present on the user's computer system, rather than
+copying library functions into the executable, and (2) will operate
+properly with a modified version of the library, if the user installs
+one, as long as the modified version is interface-compatible with the
+version that the work was made with.
+
+@item
+Accompany the work with a written offer, valid for at
+least three years, to give the same user the materials
+specified in Subsection 6a, above, for a charge no more
+than the cost of performing this distribution.
+
+@item
+If distribution of the work is made by offering access to copy
+from a designated place, offer equivalent access to copy the above
+specified materials from the same place.
+
+@item
+Verify that the user has already received a copy of these
+materials or that you have already sent this user a copy.
+@end enumerate
+
+  For an executable, the required form of the ``work that uses the
+Library'' must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies the
+executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+@item
+You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+@enumerate a
+@item
+Accompany the combined library with a copy of the same work
+based on the Library, uncombined with any other library
+facilities.  This must be distributed under the terms of the
+Sections above.
+
+@item
+Give prominent notice with the combined library of the fact
+that part of it is a work based on the Library, and explaining
+where to find the accompanying uncombined form of the same work.
+@end enumerate
+
+@item
+You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+@item
+Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+``any later version'', you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+@item
+If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.

+@appendixsubsec How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+``copyright'' line and a pointer to where the full notice is found.

+
+This library is distributed in the hope that it will be useful, but
+WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU

+
+Also add information on how to contact you by electronic and paper mail.

+You should also get your employer (if you work as a programmer) or your

+      char *java_demangle_v3(const char *mangled)
+      enum gnu_v3_ctor_kinds is_gnu_v3_mangled_ctor (const char *name)
+      enum gnu_v3_dtor_kinds is_gnu_v3_mangled_dtor (const char *name)
+
+   Also, the interface to the component list is public, and defined in
+   demangle.h.  The interface consists of these types, which are
+   defined in demangle.h:
+      enum demangle_component_type
+      struct demangle_component
+   and these functions defined in this file:
+      cplus_demangle_fill_name
+      cplus_demangle_fill_extended_operator
+      cplus_demangle_fill_ctor
+      cplus_demangle_fill_dtor
+      cplus_demangle_print
+   and other functions defined in the file cp-demint.c.
+
+   This file also defines some other functions and variables which are
+   only to be used by the file cp-demint.c.
+
+   Preprocessor macros you can define while compiling this file:
+
+   IN_LIBGCC2
+      If defined, this file defines the following function, q.v.:
+         char *__cxa_demangle (const char *mangled, char *buf, size_t *len,
+                               int *status)
+      instead of cplus_demangle_v3() and java_demangle_v3().
+
+   IN_GLIBCPP_V3
+      If defined, this file defines only __cxa_demangle(), and no other
+      publically visible functions or variables.
+
+   STANDALONE_DEMANGLER
+      If defined, this file defines a main() function which demangles
+      any arguments, or, if none, demangles stdin.
+
+   CP_DEMANGLE_DEBUG
+      If defined, turns on debugging mode, which prints information on
+      stdout about the mangled string.  This is not generally useful.

+LOCAL FUNCTION

+
+SYNOPSIS
+
+	static int
+	demangle_signature (struct work_stuff *work, const char **mangled,
+			    string *declp);
+
+DESCRIPTION
+
+	Consume and demangle the signature portion of the mangled name.
+
+	DECLP is the string where demangled output is being built.  At
+	entry it contains the demangled root name from the mangled name
+	prefix.  I.E. either a demangled operator name or the root function
+	name.  In some special cases, it may contain nothing.
+
+	*MANGLED points to the current unconsumed location in the mangled
+	name.  As tokens are consumed and demangling is performed, the
+	pointer is updated to continuously point at the next token to
+	be consumed.
+
+	Demangling GNU style mangled names is nasty because there is no
+	explicit token that marks the start of the outermost function
+	argument list.  */

+LOCAL FUNCTION
+
+	get_count -- convert an ascii count to integer, consuming tokens
+
+SYNOPSIS
+
+	static int
+	get_count (const char **type, int *count)
+
+DESCRIPTION
+
+	Assume that *type points at a count in a mangled name; set
+	*count to its value, and set *type to the next character after
+	the count.  There are some weird rules in effect here.
+
+	If *type does not point at a string of digits, return zero.
+
+	If *type points at a string of digits followed by an
+	underscore, set *count to their value as an integer, advance
+	*type to point *after the underscore, and return 1.
+
+	If *type points at a string of digits not followed by an
+	underscore, consume only the first digit.  Set *count to its
+	value as an integer, leave *type pointing after that digit,
+	and return 1.
+
+        The excuse for this odd behavior: in the ARM and HP demangling
+        styles, a type can be followed by a repeat count of the form
+        `Nxy', where:
+
+        `x' is a single digit specifying how many additional copies
+            of the type to append to the argument list, and
+
+        `y' is one or more digits, specifying the zero-based index of
+            the first repeated argument in the list.  Yes, as you're
+            unmangling the name you can figure this out yourself, but
+            it's there anyway.
+
+        So, for example, in `bar__3fooFPiN51', the first argument is a
+        pointer to an integer (`Pi'), and then the next five arguments
+        are the same (`N5'), and the first repeat is the function's
+        second argument (`1').

+   previously seen types, while lucid/ARM bases its type numbers starting
+   at one and only considers types after it has seen the 'F' character
+   indicating the start of the function args.  For lucid/ARM style, we

+Check to see if two open file descriptors refer to the same file.

+to that fd.  This can happen when we are exec'd with an already open
+file (@code{stdout} for example) or from the SVR4 @file{/proc} calls

+@deftypefn Replacement int fnmatch (const char *@var{pattern}, const char *@var{string}, int @var{flags})
+
+Matches @var{string} against @var{pattern}, returning zero if it
+matches, @code{FNM_NOMATCH} if not.  @var{pattern} may contain the
+wildcards @code{?} to match any one character, @code{*} to match any
+zero or more characters, or a set of alternate characters in square
+brackets, like @samp{[a-gt8]}, which match one character (@code{a}
+through @code{g}, or @code{t}, or @code{8}, in this example) if that one
+character is in the set.  A set may be inverted (i.e., match anything
+except what's in the set) by giving @code{^} or @code{!} as the first
+character in the set.  To include those characters in the set, list them
+as anything other than the first character of the set.  To include a
+dash in the set, list it last in the set.  A backslash character makes
+the following character not special, so for example you could match
+against a literal asterisk with @samp{\*}.  To match a literal
+backslash, use @samp{\\}.
+
+@code{flags} controls various aspects of the matching process, and is a
+boolean OR of zero or more of the following values (defined in
+@code{<fnmatch.h>}):
+
+@table @code
+
+@item FNM_PATHNAME
+@itemx FNM_FILE_NAME
+@var{string} is assumed to be a path name.  No wildcard will ever match
+@code{/}.
+
+@item FNM_NOESCAPE
+Do not interpret backslashes as quoting the following special character.
+
+@item FNM_PERIOD
+A leading period (at the beginning of @var{string}, or if
+@code{FNM_PATHNAME} after a slash) is not matched by @code{*} or
+@code{?} but must be matched explicitly.
+
+@item FNM_LEADING_DIR
+Means that @var{string} also matches @var{pattern} if some initial part
+of @var{string} matches, and is followed by @code{/} and zero or more
+characters.  For example, @samp{foo*} would match either @samp{foobar}
+or @samp{foobar/grill}.

+Ignores case when performing the comparison.

+@defvr Extension HOST_CHARSET
+This macro indicates the basic character set and encoding used by the

+It is defined by @file{safe-ctype.h}, and will be an integer constant

+
+@ftable @code
+@item HOST_CHARSET_UNKNOWN
+The host character set is unknown - that is, not one of the next two
+possibilities.
+
+@item HOST_CHARSET_ASCII
+The host character set is ASCII.
+
+@item HOST_CHARSET_EBCDIC
+The host character set is some variant of EBCDIC.  (Only one of the

+
+@c alloca.c:26
+@deftypefn Replacement void* alloca (size_t @var{size})
+
+This function allocates memory which will be automatically reclaimed
+after the procedure exits.  The @libib{} implementation does not free
+the memory immediately but will do so eventually during subsequent
+calls to this function.  Memory is allocated using @code{xmalloc} under
+normal circumstances.
+
+The header file @file{alloca-conf.h} can be used in conjunction with the
+GNU Autoconf test @code{AC_FUNC_ALLOCA} to test for and properly make
+available this function.  The @code{AC_FUNC_ALLOCA} test requires that
+client code use a block of preprocessor code to be safe (see the Autoconf
+manual for more); this header incorporates that logic and more, including
+the possibility of a GCC built-in function.
+
+@end deftypefn
+
+@c asprintf.c:32
+@deftypefn Extension int asprintf (char **@var{resptr}, const char *@var{format}, ...)
+
+Like @code{sprintf}, but instead of passing a pointer to a buffer, you
+pass a pointer to a pointer.  This function will compute the size of
+the buffer needed, allocate memory with @code{malloc}, and store a
+pointer to the allocated memory in @code{*@var{resptr}}.  The value
+returned is the same as @code{sprintf} would return.  If memory could
+not be allocated, minus one is returned and @code{NULL} is stored in
+@code{*@var{resptr}}.
+
+@end deftypefn
+
+@c atexit.c:6
+@deftypefn Supplemental int atexit (void (*@var{f})())
+

+@end deftypefn
+
+@c basename.c:6
+@deftypefn Supplemental char* basename (const char *@var{name})

+
+@end deftypefn
+
+@c bcmp.c:6
+@deftypefn Supplemental int bcmp (char *@var{x}, char *@var{y}, int @var{count})
+
+Compares the first @var{count} bytes of two areas of memory.  Returns
+zero if they are the same, nonzero otherwise.  Returns zero if
+@var{count} is zero.  A nonzero result only indicates a difference,
+it does not indicate any sorting order (say, by having a positive
+result mean @var{x} sorts before @var{y}).
+
+@end deftypefn
+
+@c bcopy.c:3
+@deftypefn Supplemental void bcopy (char *@var{in}, char *@var{out}, int @var{length})

+
+@c bsearch.c:33
+@deftypefn Supplemental void* bsearch (const void *@var{key}, const void *@var{base}, size_t @var{nmemb}, size_t @var{size}, int (*@var{compar})(const void *, const void *))
+
+Performs a search over an array of @var{nmemb} elements pointed to by
+@var{base} for a member that matches the object pointed to by @var{key}.
+The size of each member is specified by @var{size}.  The array contents
+should be sorted in ascending order according to the @var{compar}
+comparison function.  This routine should take two arguments pointing to
+the @var{key} and to an array member, in that order, and should return an
+integer less than, equal to, or greater than zero if the @var{key} object
+is respectively less than, matching, or greater than the array member.
+
+@end deftypefn
+
+@c argv.c:124
+@deftypefn Extension char** buildargv (char *@var{sp})
+
+Given a pointer to a string, parse the string extracting fields
+separated by whitespace and optionally enclosed within either single
+or double quotes (which are stripped off), and build a vector of
+pointers to copies of the string for each field.  The input string
+remains unchanged.  The last element of the vector is followed by a
+@code{NULL} element.
+
+All of the memory for the pointer array and copies of the string
+is obtained from @code{malloc}.  All of the memory can be returned to the
+system with the single function call @code{freeargv}, which takes the
+returned result of @code{buildargv}, as it's argument.
+
+Returns a pointer to the argument vector if successful.  Returns
+@code{NULL} if @var{sp} is @code{NULL} or if there is insufficient
+memory to complete building the argument vector.
+
+If the input is a null string (as opposed to a @code{NULL} pointer),
+then buildarg returns an argument vector that has one arg, a null
+string.
+
+@end deftypefn
+
+@c bzero.c:6
+@deftypefn Supplemental void bzero (char *@var{mem}, int @var{count})

+
+@end deftypefn
+
+@c calloc.c:6
+@deftypefn Supplemental void* calloc (size_t @var{nelem}, size_t @var{elsize})
+
+Uses @code{malloc} to allocate storage for @var{nelem} objects of
+@var{elsize} bytes each, then zeros the memory.
+
+@end deftypefn
+
+@c choose-temp.c:42
+@deftypefn Extension char* choose_temp_base (void)
+
+Return a prefix for temporary file names or @code{NULL} if unable to
+find one.  The current directory is chosen if all else fails so the
+program is exited if a temporary directory can't be found (@code{mktemp}
+fails).  The buffer for the result is obtained with @code{xmalloc}.
+
+This function is provided for backwards compatability only.  Its use is
+not recommended.
+
+@end deftypefn
+
+@c make-temp-file.c:87
+@deftypefn Replacement char* choose_tmpdir ()
+
+Returns a pointer to a directory path suitable for creating temporary
+files in.
+
+@end deftypefn
+
+@c clock.c:27
+@deftypefn Supplemental long clock (void)
+
+Returns an approximation of the CPU time used by the process as a
+@code{clock_t}; divide this number by @samp{CLOCKS_PER_SEC} to get the
+number of seconds used.
+
+@end deftypefn
+
+@c concat.c:24
+@deftypefn Extension char* concat (const char *@var{s1}, const char *@var{s2}, @dots{}, @code{NULL})
+
+Concatenate zero or more of strings and return the result in freshly
+@code{xmalloc}ed memory.  Returns @code{NULL} if insufficient memory is
+available.  The argument list is terminated by the first @code{NULL}
+pointer encountered.  Pointers to empty strings are ignored.
+
+@end deftypefn
+
+@c argv.c:52
+@deftypefn Extension char** dupargv (char **@var{vector})
+
+Duplicate an argument vector.  Simply scans through @var{vector},
+duplicating each argument until the terminating @code{NULL} is found.
+Returns a pointer to the argument vector if successful.  Returns
+@code{NULL} if there is insufficient memory to complete building the
+argument vector.
+
+@end deftypefn
+
+@c strerror.c:567
+@deftypefn Extension int errno_max (void)
+
+Returns the maximum @code{errno} value for which a corresponding
+symbolic name or message is available.  Note that in the case where we
+use the @code{sys_errlist} supplied by the system, it is possible for
+there to be more symbolic names than messages, or vice versa.  In
+fact, the manual page for @code{perror(3C)} explicitly warns that one
+should check the size of the table (@code{sys_nerr}) before indexing
+it, since new error codes may be added to the system before they are
+added to the table.  Thus @code{sys_nerr} might be smaller than value
+implied by the largest @code{errno} value defined in @code{<errno.h>}.
+
+We return the maximum value that can be used to obtain a meaningful
+symbolic name or message.
+
+@end deftypefn
+
+@c argv.c:293
+@deftypefn Extension void expandargv (int *@var{argcp}, char ***@var{argvp})
+
+The @var{argcp} and @code{argvp} arguments are pointers to the usual
+@code{argc} and @code{argv} arguments to @code{main}.  This function
+looks for arguments that begin with the character @samp{@@}.  Any such
+arguments are interpreted as ``response files''.  The contents of the
+response file are interpreted as additional command line options.  In
+particular, the file is separated into whitespace-separated strings;
+each such string is taken as a command-line option.  The new options
+are inserted in place of the option naming the response file, and
+@code{*argcp} and @code{*argvp} will be updated.  If the value of
+@code{*argvp} is modified by this function, then the new value has
+been dynamically allocated and can be deallocated by the caller with
+@code{freeargv}.  However, most callers will simply call
+@code{expandargv} near the beginning of @code{main} and allow the
+operating system to free the memory when the program exits.

+Check to see if two open file descriptors refer to the same file.

+wildcards @code{?} to match any one character, @code{*} to match any
+zero or more characters, or a set of alternate characters in square
+brackets, like @samp{[a-gt8]}, which match one character (@code{a}
+through @code{g}, or @code{t}, or @code{8}, in this example) if that one
+character is in the set.  A set may be inverted (i.e., match anything
+except what's in the set) by giving @code{^} or @code{!} as the first
+character in the set.  To include those characters in the set, list them
+as anything other than the first character of the set.  To include a
+dash in the set, list it last in the set.  A backslash character makes
+the following character not special, so for example you could match
+against a literal asterisk with @samp{\*}.  To match a literal
+backslash, use @samp{\\}.
+
+@code{flags} controls various aspects of the matching process, and is a

+@code{FNM_PATHNAME} after a slash) is not matched by @code{*} or
+@code{?} but must be matched explicitly.
+
+@item FNM_LEADING_DIR
+Means that @var{string} also matches @var{pattern} if some initial part
+of @var{string} matches, and is followed by @code{/} and zero or more
+characters.  For example, @samp{foo*} would match either @samp{foobar}
+or @samp{foobar/grill}.

+portion of @var{progname}, followed by a relative pathname of the
+difference between @var{bin_prefix} and @var{prefix}.
+
+If @var{progname} does not contain any directory separators,

+You must have passed @code{PEX_USE_PIPES} to the @code{pex_init} call
+that returned @var{obj}.
+
+You must close @var{fp} using @code{fclose} yourself when you have
+finished writing data to the pipeline.
+
+The file descriptor underlying @var{fp} is marked not to be inherited
+by child processes.

+On systems that do not support pipes, this function returns

+like to write code that is portable to all systems the @code{pex}
+functions support, consider using @code{pex_input_file} instead.
+
+There are two opportunities for deadlock using
+@code{pex_input_pipe}:
+
+@itemize @bullet
+@item
+Most systems' pipes can buffer only a fixed amount of data; a process
+that writes to a full pipe blocks.  Thus, if you write to @file{fp}
+before starting the first process, you run the risk of blocking when
+there is no child process yet to read the data and allow you to
+continue.  @code{pex_input_pipe} makes no promises about the
+size of the pipe's buffer, so if you need to write any data at all
+before starting the first process in the pipeline, consider using
+@code{pex_input_file} instead.
+
+@item
+Using @code{pex_input_pipe} and @code{pex_read_output} together
+may also cause deadlock.  If the output pipe fills up, so that each
+program in the pipeline is waiting for the next to read more data, and
+you fill the input pipe by writing more data to @var{fp}, then there
+is no way to make progress: the only process that could read data from
+the output pipe is you, but you are blocked on the input pipe.

+@code{NULL}.  On failure it returns an error message, a statically
+allocated string.
+
+@var{obj} is returned by a previous call to @code{pex_init}.
+
+@var{flags} is a bitwise combination of the following:
+
+@table @code
+
+@vindex PEX_LAST
+@item PEX_LAST
+This must be set on the last program in the pipeline.  In particular,
+it should be set when executing a single program.  The standard output
+of the program will be sent to @var{outname}, or, if @var{outname} is
+@code{NULL}, to the standard output of the calling program.  Do @emph{not}
+set this bit if you want to call @code{pex_read_output}
+(described below).  After a call to @code{pex_run} with this bit set,
+@var{pex_run} may no longer be called with the same @var{obj}.
+
+@vindex PEX_SEARCH
+@item PEX_SEARCH
+Search for the program using the user's executable search path.
+
+@vindex PEX_SUFFIX
+@item PEX_SUFFIX
+@var{outname} is a suffix.  See the description of @var{outname},
+below.
+
+@vindex PEX_STDERR_TO_STDOUT
+@item PEX_STDERR_TO_STDOUT
+Send the program's standard error to standard output, if possible.
+
+@vindex PEX_BINARY_INPUT
+@vindex PEX_BINARY_OUTPUT
+@item PEX_BINARY_INPUT
+@itemx PEX_BINARY_OUTPUT
+The standard input (output) of the program should be read (written) in
+binary mode rather than text mode.  These flags are ignored on systems
+which do not distinguish binary mode and text mode, such as Unix.  For
+proper behavior these flags should match appropriately---a call to
+@code{pex_run} using @code{PEX_BINARY_OUTPUT} should be followed by a
+call using @code{PEX_BINARY_INPUT}.
+@end table
+
+@var{executable} is the program to execute.  @var{argv} is the set of
+arguments to pass to the program; normally @code{@var{argv}[0]} will
+be a copy of @var{executable}.
+
+@var{outname} is used to set the name of the file to use for standard
+output.  There are two cases in which no output file will be used:
+
+@enumerate
+@item
+if @code{PEX_LAST} is not set in @var{flags}, and @code{PEX_USE_PIPES}
+was set in the call to @code{pex_init}, and the system supports pipes
+
+@item
+if @code{PEX_LAST} is set in @var{flags}, and @var{outname} is
+@code{NULL}
+@end enumerate
+
+@noindent
+Otherwise the code will use a file to hold standard
+output.  If @code{PEX_LAST} is not set, this file is considered to be
+a temporary file, and it will be removed when no longer needed, unless
+@code{PEX_SAVE_TEMPS} was set in the call to @code{pex_init}.
+
+There are two cases to consider when setting the name of the file to
+hold standard output.
+
+@enumerate
+@item
+@code{PEX_SUFFIX} is set in @var{flags}.  In this case
+@var{outname} may not be @code{NULL}.  If the @var{tempbase} parameter
+to @code{pex_init} was not @code{NULL}, then the output file name is
+the concatenation of @var{tempbase} and @var{outname}.  If
+@var{tempbase} was @code{NULL}, then the output file name is a random
+file name ending in @var{outname}.
+
+@item
+@code{PEX_SUFFIX} was not set in @var{flags}.  In this
+case, if @var{outname} is not @code{NULL}, it is used as the output
+file name.  If @var{outname} is @code{NULL}, and @var{tempbase} was
+not NULL, the output file name is randomly chosen using
+@var{tempbase}.  Otherwise the output file name is chosen completely
+at random.
+@end enumerate
+
+@var{errname} is the file name to use for standard error output.  If
+it is @code{NULL}, standard error is the same as the caller's.
+Otherwise, standard error is written to the named file.
+
+On an error return, the code sets @code{*@var{err}} to an @code{errno}
+value, or to 0 if there is no relevant @code{errno}.

+The @code{strverscmp} function compares the string @var{s1} against

+value follows the same conventions as found in the @code{strverscmp}
+function.  In fact, if @var{s1} and @var{s2} contain no digits,
+@code{strverscmp} behaves like @code{strcmp}.
+
+Basically, we compare strings normally (character by character), until
+we find a digit in each string - then we enter a special comparison
+mode, where each sequence of digits is taken as a whole.  If we reach the
+end of these two parts without noticing a difference, we return to the
+standard comparison mode.  There are two types of numeric parts:
+"integral" and "fractional" (those  begin with a '0'). The types
+of the numeric parts affect the way we sort them:
+
+@itemize @bullet
+@item
+integral/integral: we compare values as you would expect.
+
+@item
+fractional/integral: the fractional part is less than the integral one.
+Again, no surprise.
+
+@item
+fractional/fractional: the things become a bit more complex.
+If the common prefix contains only leading zeroes, the longest part is less
+than the other one; else the comparison behaves normally.

+
+Allocate memory without fail.  If @code{malloc} fails, this will print
+a message to @code{stderr} (using the name set by

+
+Duplicates a region of memory without fail.  First, @var{alloc_size} bytes
+are allocated, then @var{copy_size} bytes from @var{input} are copied into
+it, and the new memory is returned.  If fewer bytes are copied than were

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */

+   I got it by extracting all the identifiers from all the source code
+   I had lying around in mid-1999, and testing many recurrences of
+   the form "H_n = H_{n-1} * K + c_n * L + M" where K, L, M were either
+   prime numbers or the appropriate identity.  This was the best one.
+   I don't remember exactly what constituted "best", except I was
+   looking at bucket-length distributions mostly.
+   
+   So it should be very good at hashing identifiers, but might not be
+   as good at arbitrary strings.
+   
+   I'll add that it thoroughly trounces the hash functions recommended
+   for this use at http://burtleburtle.net/bob/hash/index.html, both
+   on speed and bucket distribution.  I haven't tried it against the
+   function they just started using for Perl's hashes.  */

+mix() was built out of 36 single-cycle latency instructions in a 
+  structure that could supported 2x parallelism, like so:
+      a -= b; 
+      a -= c; x = (c>>13);

+  Unfortunately, superscalar Pentiums and Sparcs can't take advantage 
+  of that parallelism.  They've also turned some of those single-cycle
+  latency instructions into multi-cycle latency instructions.  Still,

+Returns a 32-bit value.  Every bit of the key affects every bit of
+the return value.  Every 1-bit and 2-bit delta achieves avalanche.
+About 36+6len instructions.
+
+The best hash table sizes are powers of 2.  There is no need to do
+mod a prime (mod is sooo slow!).  If you need less than 32 bits,
+use a bitmask.  For example, if you need only 10 bits, do
+  h = (h & hashmask(10));
+In which case, the hash table should have hashsize(10) elements.
+
+If you are hashing n strings (ub1 **)k, do it like this:
+  for (i=0, h=0; i<n; ++i) h = hash( k[i], len[i], h);

+@cindex libiberty usage
+@cindex how to use
+
+@c THIS SECTION IS CRAP AND NEEDS REWRITING BADLY.
+
+To date, @libib{} is generally not installed on its own.  It has evolved
+over years but does not have its own version number nor release schedule.
+
+Possibly the easiest way to use @libib{} in your projects is to drop the
+@libib{} code into your project's sources, and to build the library along
+with your own sources; the library would then be linked in at the end.  This
+prevents any possible version mismatches with other copies of libiberty
+elsewhere on the system.
+
+Passing @option{--enable-install-libiberty} to the @command{configure}
+script when building @libib{} causes the header files and archive library
+to be installed when @kbd{make install} is run.  This option also takes
+an (optional) argument to specify the installation location, in the same
+manner as @option{--prefix}.
+
+For your own projects, an approach which offers stability and flexibility
+is to include @libib{} with your code, but allow the end user to optionally
+choose to use a previously-installed version instead.  In this way the
+user may choose (for example) to install @libib{} as part of GCC, and use
+that version for all software built with that compiler.  (This approach
+has proven useful with software using the GNU @code{readline} library.)
+
+Making use of @libib{} code usually requires that you include one or more
+header files from the @libib{} distribution.  (They will be named as
+necessary in the function descriptions.)  At link time, you will need to
+add @option{-liberty} to your link command invocation.
+
+
+@node Overview
+@chapter Overview
+
+Functions contained in @libib{} can be divided into three general categories.
+
+
+@menu
+* Supplemental Functions::       Providing functions which don't exist
+                                 on older operating systems.
+
+* Replacement Functions::        These functions are sometimes buggy or
+                                 unpredictable on some operating systems.
+
+* Extensions::                   Functions which provide useful extensions
+                                 or safety wrappers around existing code.
+@end menu
+
+@node Supplemental Functions
+@section Supplemental Functions
+@cindex supplemental functions
+@cindex functions, supplemental
+@cindex functions, missing
+
+Certain operating systems do not provide functions which have since
+become standardized, or at least common.  For example, the Single
+Unix Specification Version 2 requires that the @code{basename}
+function be provided, but an OS which predates that specification
+might not have this function.  This should not prevent well-written
+code from running on such a system.
+
+Similarly, some functions exist only among a particular ``flavor''
+or ``family'' of operating systems.  As an example, the @code{bzero}
+function is often not present on systems outside the BSD-derived
+family of systems.
+
+Many such functions are provided in @libib{}.  They are quickly
+listed here with little description, as systems which lack them
+become less and less common.  Each function @var{foo} is implemented
+in @file{@var{foo}.c} but not declared in any @libib{} header file; more
+comments and caveats for each function's implementation are often
+available in the source file.  Generally, the function can simply
+be declared as @code{extern}.
+
+
+
+@node Replacement Functions
+@section Replacement Functions
+@cindex replacement functions
+@cindex functions, replacement
+
+Some functions have extremely limited implementations on different
+platforms.  Other functions are tedious to use correctly; for example,
+proper use of @code{malloc} calls for the return value to be checked and
+appropriate action taken if memory has been exhausted.  A group of
+``replacement functions'' is available in @libib{} to address these issues
+for some of the most commonly used subroutines.
+
+All of these functions are declared in the @file{libiberty.h} header
+file.  Many of the implementations will use preprocessor macros set by
+GNU Autoconf, if you decide to make use of that program.  Some of these
+functions may call one another.
+
+
+@menu
+* Memory Allocation::            Testing and handling failed memory
+                                   requests automatically.
+* Exit Handlers::                Calling routines on program exit.
+* Error Reporting::              Mapping errno and signal numbers to
+                                   more useful string formats.
+@end menu
+
+@node Memory Allocation
+@subsection Memory Allocation
+@cindex memory allocation
+
+The functions beginning with the letter @samp{x} are wrappers around
+standard functions; the functions provided by the system environment
+are called and their results checked before the results are passed back
+to client code.  If the standard functions fail, these wrappers will
+terminate the program.  Thus, these versions can be used with impunity.
+
+
+@node Exit Handlers
+@subsection Exit Handlers
+@cindex exit handlers
+
+The existence and implementation of the @code{atexit} routine varies
+amongst the flavors of Unix.  @libib{} provides an unvarying dependable
+implementation via @code{xatexit} and @code{xexit}.
+
+
+@node Error Reporting
+@subsection Error Reporting
+@cindex error reporting
+
+These are a set of routines to facilitate programming with the system
+@code{errno} interface.  The @libib{} source file @file{strerror.c}
+contains a good deal of documentation for these functions.
+
+@c signal stuff
+
+
+@node Extensions
+@section Extensions
+@cindex extensions
+@cindex functions, extension
+
+@libib{} includes additional functionality above and beyond standard
+functions, which has proven generically useful in GNU programs, such as
+obstacks and regex.  These functions are often copied from other
+projects as they gain popularity, and are included here to provide a
+central location from which to use, maintain, and distribute them.
+
+@menu
+* Obstacks::                     Stacks of arbitrary objects.

+@deftypefn Extension {const char*} make_relative_prefix (const char *@var{progname}, const char *@var{bin_prefix}, const char *@var{prefix})
+
+Given three paths @var{progname}, @var{bin_prefix}, @var{prefix},
+return the path that is in the same position relative to
+@var{progname}'s directory as @var{prefix} is relative to
+@var{bin_prefix}.  That is, a string starting with the directory
+portion of @var{progname}, followed by a relative pathname of the
+difference between @var{bin_prefix} and @var{prefix}.
+
+If @var{progname} does not contain any directory separators,
+@code{make_relative_prefix} will search @env{PATH} to find a program
+named @var{progname}.  Also, if @var{progname} is a symbolic link,
+the symbolic link will be resolved.
+
+For example, if @var{bin_prefix} is @code{/alpha/beta/gamma/gcc/delta},
+@var{prefix} is @code{/alpha/beta/gamma/omega/}, and @var{progname} is
+@code{/red/green/blue/gcc}, then this function will return
+@code{/red/green/blue/../../omega/}.
+
+The return value is normally allocated via @code{malloc}.  If no
+relative prefix can be found, return @code{NULL}.

+@cindex obstacks
+
+An @dfn{obstack} is a pool of memory containing a stack of objects.  You
+can create any number of separate obstacks, and then allocate objects in
+specified obstacks.  Within each obstack, the last object allocated must
+always be the first one freed, but distinct obstacks are independent of
+each other.
+
+Aside from this one constraint of order of freeing, obstacks are totally
+general: an obstack can contain any number of objects of any size.  They
+are implemented with macros, so allocation is usually very fast as long as
+the objects are usually small.  And the only space overhead per object is
+the padding needed to start each object on a suitable boundary.

+An obstack is represented by a data structure of type @code{struct
+obstack}.  This structure has a small fixed size; it records the status
+of the obstack and how to find the space in which objects are allocated.
+It does not contain any of the objects themselves.  You should not try

+described in this chapter.
+@end deftp
+
+You can declare variables of type @code{struct obstack} and use them as
+obstacks, or you can allocate obstacks dynamically like any other kind
+of object.  Dynamic allocation of obstacks allows your program to have a
+variable number of different stacks.  (You can even allocate an
+obstack structure in another obstack, but this is rarely useful.)
+
+All the functions that work with obstacks require you to specify which
+obstack to use.  You do this with a pointer of type @code{struct obstack
+*}.  In the following, we often say ``an obstack'' when strictly
+speaking the object at hand is such a pointer.
+
+The objects in the obstack are packed into large blocks called
+@dfn{chunks}.  The @code{struct obstack} structure points to a chain of
+the chunks currently in use.
+
+The obstack library obtains a new chunk whenever you allocate an object
+that won't fit in the previous chunk.  Since the obstack library manages
+chunks automatically, you don't need to pay much attention to them, but
+you do need to supply a function which the obstack library should use to
+get a chunk.  Usually you supply a function which uses @code{malloc}
+directly or indirectly.  You must also supply a function to free a chunk.
+These matters are described in the following section.
+
+@node Preparing for Obstacks
+@section Preparing for Using Obstacks
+
+Each source file in which you plan to use the obstack functions
+must include the header file @file{obstack.h}, like this:
+
+@smallexample
+#include <obstack.h>
+@end smallexample
+
+@findex obstack_chunk_alloc
+@findex obstack_chunk_free
+Also, if the source file uses the macro @code{obstack_init}, it must
+declare or define two functions or macros that will be called by the
+obstack library.  One, @code{obstack_chunk_alloc}, is used to allocate
+the chunks of memory into which objects are packed.  The other,
+@code{obstack_chunk_free}, is used to return chunks when the objects in
+them are freed.  These macros should appear before any use of obstacks
+in the source file.
+
+Usually these are defined to use @code{malloc} via the intermediary
+@code{xmalloc} (@pxref{Unconstrained Allocation, , , libc, The GNU C Library Reference Manual}).  This is done with
+the following pair of macro definitions:
+
+@smallexample
+#define obstack_chunk_alloc xmalloc
+#define obstack_chunk_free free
+@end smallexample
+
+@noindent
+Though the memory you get using obstacks really comes from @code{malloc},
+using obstacks is faster because @code{malloc} is called less often, for
+larger blocks of memory.  @xref{Obstack Chunks}, for full details.
+
+At run time, before the program can use a @code{struct obstack} object
+as an obstack, it must initialize the obstack by calling
+@code{obstack_init}.
+
+@comment obstack.h
+@comment GNU
+@deftypefun int obstack_init (struct obstack *@var{obstack-ptr})
+Initialize obstack @var{obstack-ptr} for allocation of objects.  This
+function calls the obstack's @code{obstack_chunk_alloc} function.  If
+allocation of memory fails, the function pointed to by
+@code{obstack_alloc_failed_handler} is called.  The @code{obstack_init}
+function always returns 1 (Compatibility notice: Former versions of
+obstack returned 0 if allocation failed).
+@end deftypefun
+
+Here are two examples of how to allocate the space for an obstack and
+initialize it.  First, an obstack that is a static variable:
+
+@smallexample
+static struct obstack myobstack;
+@dots{}
+obstack_init (&myobstack);
+@end smallexample
+
+@noindent
+Second, an obstack that is itself dynamically allocated:
+
+@smallexample
+struct obstack *myobstack_ptr
+  = (struct obstack *) xmalloc (sizeof (struct obstack));
+
+obstack_init (myobstack_ptr);
+@end smallexample
+
+@comment obstack.h
+@comment GNU
+@defvar obstack_alloc_failed_handler
+The value of this variable is a pointer to a function that
+@code{obstack} uses when @code{obstack_chunk_alloc} fails to allocate
+memory.  The default action is to print a message and abort.
+You should supply a function that either calls @code{exit}
+(@pxref{Program Termination, , , libc, The GNU C Library Reference Manual}) or @code{longjmp} (@pxref{Non-Local
+Exits, , , libc, The GNU C Library Reference Manual}) and doesn't return.
+
+@smallexample
+void my_obstack_alloc_failed (void)
+@dots{}
+obstack_alloc_failed_handler = &my_obstack_alloc_failed;
+@end smallexample
+
+@end defvar
+
+@node Allocation in an Obstack
+@section Allocation in an Obstack
+@cindex allocation (obstacks)
+
+The most direct way to allocate an object in an obstack is with
+@code{obstack_alloc}, which is invoked almost like @code{malloc}.
+
+@comment obstack.h
+@comment GNU
+@deftypefun {void *} obstack_alloc (struct obstack *@var{obstack-ptr}, int @var{size})
+This allocates an uninitialized block of @var{size} bytes in an obstack
+and returns its address.  Here @var{obstack-ptr} specifies which obstack
+to allocate the block in; it is the address of the @code{struct obstack}
+object which represents the obstack.  Each obstack function or macro
+requires you to specify an @var{obstack-ptr} as the first argument.
+
+This function calls the obstack's @code{obstack_chunk_alloc} function if
+it needs to allocate a new chunk of memory; it calls
+@code{obstack_alloc_failed_handler} if allocation of memory by
+@code{obstack_chunk_alloc} failed.
+@end deftypefun
+
+For example, here is a function that allocates a copy of a string @var{str}
+in a specific obstack, which is in the variable @code{string_obstack}:
+
+@smallexample
+struct obstack string_obstack;
+
+char *
+copystring (char *string)
+@{
+  size_t len = strlen (string) + 1;
+  char *s = (char *) obstack_alloc (&string_obstack, len);
+  memcpy (s, string, len);
+  return s;
+@}
+@end smallexample
+
+To allocate a block with specified contents, use the function
+@code{obstack_copy}, declared like this:
+
+@comment obstack.h
+@comment GNU
+@deftypefun {void *} obstack_copy (struct obstack *@var{obstack-ptr}, void *@var{address}, int @var{size})
+This allocates a block and initializes it by copying @var{size}
+bytes of data starting at @var{address}.  It calls
+@code{obstack_alloc_failed_handler} if allocation of memory by
+@code{obstack_chunk_alloc} failed.
+@end deftypefun
+
+@comment obstack.h
+@comment GNU
+@deftypefun {void *} obstack_copy0 (struct obstack *@var{obstack-ptr}, void *@var{address}, int @var{size})
+Like @code{obstack_copy}, but appends an extra byte containing a null
+character.  This extra byte is not counted in the argument @var{size}.
+@end deftypefun
+
+The @code{obstack_copy0} function is convenient for copying a sequence
+of characters into an obstack as a null-terminated string.  Here is an
+example of its use:
+
+@smallexample
+char *
+obstack_savestring (char *addr, int size)
+@{
+  return obstack_copy0 (&myobstack, addr, size);
+@}
+@end smallexample
+
+@noindent
+Contrast this with the previous example of @code{savestring} using
+@code{malloc} (@pxref{Basic Allocation, , , libc, The GNU C Library Reference Manual}).
+
+@node Freeing Obstack Objects
+@section Freeing Objects in an Obstack
+@cindex freeing (obstacks)
+
+To free an object allocated in an obstack, use the function
+@code{obstack_free}.  Since the obstack is a stack of objects, freeing
+one object automatically frees all other objects allocated more recently
+in the same obstack.
+
+@comment obstack.h
+@comment GNU
+@deftypefun void obstack_free (struct obstack *@var{obstack-ptr}, void *@var{object})
+If @var{object} is a null pointer, everything allocated in the obstack
+is freed.  Otherwise, @var{object} must be the address of an object
+allocated in the obstack.  Then @var{object} is freed, along with
+everything allocated in @var{obstack} since @var{object}.
+@end deftypefun
+
+Note that if @var{object} is a null pointer, the result is an
+uninitialized obstack.  To free all memory in an obstack but leave it
+valid for further allocation, call @code{obstack_free} with the address
+of the first object allocated on the obstack:
+
+@smallexample
+obstack_free (obstack_ptr, first_object_allocated_ptr);
+@end smallexample
+
+Recall that the objects in an obstack are grouped into chunks.  When all
+the objects in a chunk become free, the obstack library automatically
+frees the chunk (@pxref{Preparing for Obstacks}).  Then other
+obstacks, or non-obstack allocation, can reuse the space of the chunk.
+
+@node Obstack Functions
+@section Obstack Functions and Macros
+@cindex macros
+
+The interfaces for using obstacks may be defined either as functions or
+as macros, depending on the compiler.  The obstack facility works with
+all C compilers, including both @w{ISO C} and traditional C, but there are
+precautions you must take if you plan to use compilers other than GNU C.
+
+If you are using an old-fashioned @w{non-ISO C} compiler, all the obstack
+``functions'' are actually defined only as macros.  You can call these
+macros like functions, but you cannot use them in any other way (for
+example, you cannot take their address).
+
+Calling the macros requires a special precaution: namely, the first
+operand (the obstack pointer) may not contain any side effects, because
+it may be computed more than once.  For example, if you write this:
+
+@smallexample
+obstack_alloc (get_obstack (), 4);
+@end smallexample
+
+@noindent
+you will find that @code{get_obstack} may be called several times.
+If you use @code{*obstack_list_ptr++} as the obstack pointer argument,
+you will get very strange results since the incrementation may occur
+several times.
+
+In @w{ISO C}, each function has both a macro definition and a function
+definition.  The function definition is used if you take the address of the
+function without calling it.  An ordinary call uses the macro definition by
+default, but you can request the function definition instead by writing the
+function name in parentheses, as shown here:
+
+@smallexample
+char *x;
+void *(*funcp) ();
+/* @r{Use the macro}.  */
+x = (char *) obstack_alloc (obptr, size);
+/* @r{Call the function}.  */
+x = (char *) (obstack_alloc) (obptr, size);
+/* @r{Take the address of the function}.  */
+funcp = obstack_alloc;
+@end smallexample
+
+@noindent
+This is the same situation that exists in @w{ISO C} for the standard library
+functions.  @xref{Macro Definitions, , , libc, The GNU C Library Reference Manual}.
+
+@strong{Warning:} When you do use the macros, you must observe the
+precaution of avoiding side effects in the first operand, even in @w{ISO C}.
+
+If you use the GNU C compiler, this precaution is not necessary, because
+various language extensions in GNU C permit defining the macros so as to
+compute each argument only once.
+
+@node Growing Objects
+@section Growing Objects
+@cindex growing objects (in obstacks)
+@cindex changing the size of a block (obstacks)
+
+Because memory in obstack chunks is used sequentially, it is possible to
+build up an object step by step, adding one or more bytes at a time to the
+end of the object.  With this technique, you do not need to know how much
+data you will put in the object until you come to the end of it.  We call
+this the technique of @dfn{growing objects}.  The special functions
+for adding data to the growing object are described in this section.
+
+You don't need to do anything special when you start to grow an object.
+Using one of the functions to add data to the object automatically
+starts it.  However, it is necessary to say explicitly when the object is
+finished.  This is done with the function @code{obstack_finish}.
+
+The actual address of the object thus built up is not known until the
+object is finished.  Until then, it always remains possible that you will
+add so much data that the object must be copied into a new chunk.
+
+While the obstack is in use for a growing object, you cannot use it for
+ordinary allocation of another object.  If you try to do so, the space
+already added to the growing object will become part of the other object.

+
+This function can return a null pointer under the same conditions as
+@code{obstack_alloc} (@pxref{Allocation in an Obstack}).
+@end deftypefun
+
+When you build an object by growing it, you will probably need to know
+afterward how long it became.  You need not keep track of this as you grow
+the object, because you can find out the length from the obstack just
+before finishing the object with the function @code{obstack_object_size},
+declared as follows:
+
+@comment obstack.h
+@comment GNU
+@deftypefun int obstack_object_size (struct obstack *@var{obstack-ptr})
+This function returns the current size of the growing object, in bytes.
+Remember to call this function @emph{before} finishing the object.
+After it is finished, @code{obstack_object_size} will return zero.
+@end deftypefun
+
+If you have started growing an object and wish to cancel it, you should
+finish it and then free it, like this:
+
+@smallexample
+obstack_free (obstack_ptr, obstack_finish (obstack_ptr));
+@end smallexample
+
+@noindent
+This has no effect if no object was growing.
+
+@cindex shrinking objects
+You can use @code{obstack_blank} with a negative size argument to make
+the current object smaller.  Just don't try to shrink it beyond zero
+length---there's no telling what will happen if you do that.
+
+@node Extra Fast Growing
+@section Extra Fast Growing Objects
+@cindex efficiency and obstacks
+
+The usual functions for growing objects incur overhead for checking
+whether there is room for the new growth in the current chunk.  If you
+are frequently constructing objects in small steps of growth, this
+overhead can be significant.
+
+You can reduce the overhead by using special ``fast growth''
+functions that grow the object without checking.  In order to have a
+robust program, you must do the checking yourself.  If you do this checking
+in the simplest way each time you are about to add data to the object, you
+have not saved anything, because that is what the ordinary growth
+functions do.  But if you can arrange to check less often, or check
+more efficiently, then you make the program faster.
+
+The function @code{obstack_room} returns the amount of room available
+in the current chunk.  It is declared as follows:
+
+@comment obstack.h
+@comment GNU
+@deftypefun int obstack_room (struct obstack *@var{obstack-ptr})
+This returns the number of bytes that can be added safely to the current
+growing object (or to an object about to be started) in obstack
+@var{obstack} using the fast growth functions.
+@end deftypefun

+for adding data to a growing object:

+@end deftypefun
+
+When you check for space using @code{obstack_room} and there is not
+enough room for what you want to add, the fast growth functions
+are not safe.  In this case, simply use the corresponding ordinary
+growth function instead.  Very soon this will copy the object to a
+new chunk; then there will be lots of room available again.
+
+So, each time you use an ordinary growth function, check afterward for
+sufficient space using @code{obstack_room}.  Once the object is copied
+to a new chunk, there will be plenty of space again, so the program will
+start using the fast growth functions again.

+@node Obstacks Data Alignment
+@section Alignment of Data in Obstacks
+@cindex alignment (in obstacks)
+
+Each obstack has an @dfn{alignment boundary}; each object allocated in
+the obstack automatically starts on an address that is a multiple of the
+specified boundary.  By default, this boundary is 4 bytes.
+
+To access an obstack's alignment boundary, use the macro
+@code{obstack_alignment_mask}, whose function prototype looks like
+this:
+
+@comment obstack.h
+@comment GNU
+@deftypefn Macro int obstack_alignment_mask (struct obstack *@var{obstack-ptr})
+The value is a bit mask; a bit that is 1 indicates that the corresponding
+bit in the address of an object should be 0.  The mask value should be one
+less than a power of 2; the effect is that all object addresses are
+multiples of that power of 2.  The default value of the mask is 3, so that
+addresses are multiples of 4.  A mask value of 0 means an object can start
+on any multiple of 1 (that is, no alignment is required).
+
+The expansion of the macro @code{obstack_alignment_mask} is an lvalue,
+so you can alter the mask by assignment.  For example, this statement:
+
+@smallexample
+obstack_alignment_mask (obstack_ptr) = 0;
+@end smallexample
+
+@noindent
+has the effect of turning off alignment processing in the specified obstack.
+@end deftypefn
+
+Note that a change in alignment mask does not take effect until
+@emph{after} the next time an object is allocated or finished in the
+obstack.  If you are not growing an object, you can make the new
+alignment mask take effect immediately by calling @code{obstack_finish}.
+This will finish a zero-length object and then do proper alignment for
+the next object.
+
+@node Obstack Chunks
+@section Obstack Chunks
+@cindex efficiency of chunks
+@cindex chunks
+
+Obstacks work by allocating space for themselves in large chunks, and
+then parceling out space in the chunks to satisfy your requests.  Chunks
+are normally 4096 bytes long unless you specify a different chunk size.
+The chunk size includes 8 bytes of overhead that are not actually used
+for storing objects.  Regardless of the specified size, longer chunks
+will be allocated when necessary for long objects.
+
+The obstack library allocates chunks by calling the function
+@code{obstack_chunk_alloc}, which you must define.  When a chunk is no
+longer needed because you have freed all the objects in it, the obstack
+library frees the chunk by calling @code{obstack_chunk_free}, which you
+must also define.
+
+These two must be defined (as macros) or declared (as functions) in each
+source file that uses @code{obstack_init} (@pxref{Creating Obstacks}).
+Most often they are defined as macros like this:
+
+@smallexample
+#define obstack_chunk_alloc malloc
+#define obstack_chunk_free free
+@end smallexample
+
+Note that these are simple macros (no arguments).  Macro definitions with
+arguments will not work!  It is necessary that @code{obstack_chunk_alloc}
+or @code{obstack_chunk_free}, alone, expand into a function name if it is
+not itself a function name.
+
+If you allocate chunks with @code{malloc}, the chunk size should be a
+power of 2.  The default chunk size, 4096, was chosen because it is long
+enough to satisfy many typical requests on the obstack yet short enough
+not to waste too much memory in the portion of the last chunk not yet used.
+
+@comment obstack.h
+@comment GNU
+@deftypefn Macro int obstack_chunk_size (struct obstack *@var{obstack-ptr})
+This returns the chunk size of the given obstack.
+@end deftypefn
+
+Since this macro expands to an lvalue, you can specify a new chunk size by
+assigning it a new value.  Doing so does not affect the chunks already
+allocated, but will change the size of chunks allocated for that particular
+obstack in the future.  It is unlikely to be useful to make the chunk size
+smaller, but making it larger might improve efficiency if you are
+allocating many objects whose size is comparable to the chunk size.  Here
+is how to do so cleanly:
+
+@smallexample

+@vindex PEX_BINARY_OUTPUT
+@item PEX_BINARY_INPUT
+@itemx PEX_BINARY_OUTPUT
+The standard input (output) of the program should be read (written) in
+binary mode rather than text mode.  These flags are ignored on systems
+which do not distinguish binary mode and text mode, such as Unix.  For
+proper behavior these flags should match appropriately---a call to
+@code{pex_run} using @code{PEX_BINARY_OUTPUT} should be followed by a
+call using @code{PEX_BINARY_INPUT}.
+@end table
+
+@var{executable} is the program to execute.  @var{argv} is the set of
+arguments to pass to the program; normally @code{@var{argv}[0]} will
+be a copy of @var{executable}.
+
+@var{outname} is used to set the name of the file to use for standard
+output.  There are two cases in which no output file will be used:
+
+@enumerate
+@item
+if @code{PEX_LAST} is not set in @var{flags}, and @code{PEX_USE_PIPES}
+was set in the call to @code{pex_init}, and the system supports pipes
+
+@item
+if @code{PEX_LAST} is set in @var{flags}, and @var{outname} is
+@code{NULL}
+@end enumerate
+
+@noindent
+Otherwise the code will use a file to hold standard
+output.  If @code{PEX_LAST} is not set, this file is considered to be
+a temporary file, and it will be removed when no longer needed, unless
+@code{PEX_SAVE_TEMPS} was set in the call to @code{pex_init}.
+
+There are two cases to consider when setting the name of the file to
+hold standard output.
+
+@enumerate
+@item
+@code{PEX_SUFFIX} is set in @var{flags}.  In this case
+@var{outname} may not be @code{NULL}.  If the @var{tempbase} parameter
+to @code{pex_init} was not @code{NULL}, then the output file name is
+the concatenation of @var{tempbase} and @var{outname}.  If
+@var{tempbase} was @code{NULL}, then the output file name is a random
+file name ending in @var{outname}.
+
+@item
+@code{PEX_SUFFIX} was not set in @var{flags}.  In this
+case, if @var{outname} is not @code{NULL}, it is used as the output
+file name.  If @var{outname} is @code{NULL}, and @var{tempbase} was
+not NULL, the output file name is randomly chosen using
+@var{tempbase}.  Otherwise the output file name is chosen completely
+at random.
+@end enumerate
+
+@var{errname} is the file name to use for standard error output.  If
+it is @code{NULL}, standard error is the same as the caller's.
+Otherwise, standard error is written to the named file.
+
+On an error return, the code sets @code{*@var{err}} to an @code{errno}
+value, or to 0 if there is no relevant @code{errno}.
+
+@end deftypefn
+
+@deftypefn Extension {const char *} pex_run_in_environment (struct pex_obj *@var{obj}, int @var{flags}, const char *@var{executable}, char * const *@var{argv}, char * const *@var{env}, int @var{env_size}, const char *@var{outname}, const char *@var{errname}, int *@var{err})
+
+Execute one program in a pipeline, permitting the environment for the
+program to be specified.  Behaviour and parameters not listed below are
+as for @code{pex_run}.
+
+@var{env} is the environment for the child process, specified as an array of
+character pointers.  Each element of the array should point to a string of the
+form @code{VAR=VALUE}, with the exception of the last element that must be
+@code{NULL}.
+
+@end deftypefn
+
+@deftypefn Extension {FILE *} pex_input_file (struct pex_obj *@var{obj}, int @var{flags}, const char *@var{in_name})
+
+Return a stream for a temporary file to pass to the first program in
+the pipeline as input.
+
+The name of the input file is chosen according to the same rules
+@code{pex_run} uses to choose output file names, based on
+@var{in_name}, @var{obj} and the @code{PEX_SUFFIX} bit in @var{flags}.
+
+Don't call @code{fclose} on the returned stream; the first call to
+@code{pex_run} closes it automatically.
+
+If @var{flags} includes @code{PEX_BINARY_OUTPUT}, open the stream in
+binary mode; otherwise, open it in the default mode.  Including
+@code{PEX_BINARY_OUTPUT} in @var{flags} has no effect on Unix.
+@end deftypefn
+
+@deftypefn Extension {FILE *} pex_input_pipe (struct pex_obj *@var{obj}, int @var{binary})
+
+Return a stream @var{fp} for a pipe connected to the standard input of
+the first program in the pipeline; @var{fp} is opened for writing.
+You must have passed @code{PEX_USE_PIPES} to the @code{pex_init} call
+that returned @var{obj}.
+
+You must close @var{fp} using @code{fclose} yourself when you have
+finished writing data to the pipeline.
+
+The file descriptor underlying @var{fp} is marked not to be inherited
+by child processes.
+
+On systems that do not support pipes, this function returns
+@code{NULL}, and sets @code{errno} to @code{EINVAL}.  If you would
+like to write code that is portable to all systems the @code{pex}
+functions support, consider using @code{pex_input_file} instead.
+
+There are two opportunities for deadlock using
+@code{pex_input_pipe}:
+
+@itemize @bullet
+@item
+Most systems' pipes can buffer only a fixed amount of data; a process
+that writes to a full pipe blocks.  Thus, if you write to @file{fp}
+before starting the first process, you run the risk of blocking when
+there is no child process yet to read the data and allow you to
+continue.  @code{pex_input_pipe} makes no promises about the
+size of the pipe's buffer, so if you need to write any data at all
+before starting the first process in the pipeline, consider using
+@code{pex_input_file} instead.
+
+@item
+Using @code{pex_input_pipe} and @code{pex_read_output} together
+may also cause deadlock.  If the output pipe fills up, so that each
+program in the pipeline is waiting for the next to read more data, and
+you fill the input pipe by writing more data to @var{fp}, then there
+is no way to make progress: the only process that could read data from
+the output pipe is you, but you are blocked on the input pipe.
+
+@end itemize
+
+@end deftypefn
+
+@deftypefn Extension {FILE *} pex_read_output (struct pex_obj *@var{obj}, int @var{binary})
+
+Returns a @code{FILE} pointer which may be used to read the standard
+output of the last program in the pipeline.  When this is used,
+@code{PEX_LAST} should not be used in a call to @code{pex_run}.  After
+this is called, @code{pex_run} may no longer be called with the same
+@var{obj}.  @var{binary} should be non-zero if the file should be
+opened in binary mode.  Don't call @code{fclose} on the returned file;
+it will be closed by @code{pex_free}.
+
+@end deftypefn
+
+@deftypefn Extension int pex_get_status (struct pex_obj *@var{obj}, int @var{count}, int *@var{vector})
+
+Returns the exit status of all programs run using @var{obj}.
+@var{count} is the number of results expected.  The results will be
+placed into @var{vector}.  The results are in the order of the calls
+to @code{pex_run}.  Returns 0 on error, 1 on success.
+
+@end deftypefn
+
+@deftypefn Extension int pex_get_times (struct pex_obj *@var{obj}, int @var{count}, struct pex_time *@var{vector})
+
+Returns the process execution times of all programs run using
+@var{obj}.  @var{count} is the number of results expected.  The
+results will be placed into @var{vector}.  The results are in the
+order of the calls to @code{pex_run}.  Returns 0 on error, 1 on
+success.
+
+@code{struct pex_time} has the following fields of the type
+@code{unsigned long}: @code{user_seconds},
+@code{user_microseconds}, @code{system_seconds},
+@code{system_microseconds}.  On systems which do not support reporting
+process times, all the fields will be set to @code{0}.
+
+@end deftypefn
+
+@deftypefn Extension void pex_free (struct pex_obj @var{obj})
+
+Clean up and free all data associated with @var{obj}.
+
+@end deftypefn
+
+@deftypefn Extension {const char *} pex_one (int @var{flags}, const char *@var{executable}, char * const *@var{argv}, const char *@var{pname}, const char *@var{outname}, const char *@var{errname}, int *@var{status}, int *@var{err})
+
+An interface to permit the easy execution of a
+single program.  The return value and most of the parameters are as
+for a call to @code{pex_run}.  @var{flags} is restricted to a
+combination of @code{PEX_SEARCH}, @code{PEX_STDERR_TO_STDOUT}, and
+@code{PEX_BINARY_OUTPUT}.  @var{outname} is interpreted as if
+@code{PEX_LAST} were set.  On a successful return, @code{*@var{status}} will
+be set to the exit status of the program.
+
+@end deftypefn
+
+@deftypefn Extension int pexecute (const char *@var{program}, char * const *@var{argv}, const char *@var{this_pname}, const char *@var{temp_base}, char **@var{errmsg_fmt}, char **@var{errmsg_arg}, int flags)
+
+This is the old interface to execute one or more programs.  It is
+still supported for compatibility purposes, but is no longer
+documented.
+
+@end deftypefn
+
+@deftypefn Extension int pwait (int @var{pid}, int *@var{status}, int @var{flags})
+
+Another part of the old execution interface.

+/* An improved random number generation package.  In addition to the standard
+   rand()/srand() like interface, this package also has a special state info
+   interface.  The initstate() routine is called with a seed, an array of
+   bytes, and a count of how many bytes are being passed in; this array is
+   then initialized to contain information for random number generation with
+   that much state information.  Good sizes for the amount of state
+   information are 32, 64, 128, and 256 bytes.  The state can be switched by
+   calling the setstate() function with the same array as was initiallized
+   with initstate().  By default, the package runs with 128 bytes of state
+   information and generates far better random numbers than a linear
+   congruential generator.  If the amount of state information is less than
+   32 bytes, a simple linear congruential R.N.G. is used.  Internally, the
+   state information is treated as an array of longs; the zeroeth element of
+   the array is the type of R.N.G. being used (small integer); the remainder
+   of the array is the state information for the R.N.G.  Thus, 32 bytes of
+   state information will give 7 longs worth of state information, which will
+   allow a degree seven polynomial.  (Note: The zeroeth word of state
+   information also has some other information stored in it; see setstate
+   for details).  The random number generation technique is a linear feedback
+   shift register approach, employing trinomials (since there are fewer terms
+   to sum up that way).  In this approach, the least significant bit of all
+   the numbers in the state table will act as a linear feedback shift register,
+   and will have period 2^deg - 1 (where deg is the degree of the polynomial
+   being used, assuming that the polynomial is irreducible and primitive).
+   The higher order bits will have longer periods, since their values are
+   also influenced by pseudo-random carries out of the lower bits.  The
+   total period of the generator is approximately deg*(2**deg - 1); thus
+   doubling the amount of state information has a vast influence on the
+   period of the generator.  Note: The deg*(2**deg - 1) is an approximation
+   only good for large deg, when the period of the shift register is the
+   dominant factor.  With deg equal to seven, the period is actually much
+   longer than the 7*(2**7 - 1) predicted by this formula.  */

+@defvr Extension HOST_CHARSET
+This macro indicates the basic character set and encoding used by the
+host: more precisely, the encoding used for character constants in
+preprocessor @samp{#if} statements (the C "execution character set").
+It is defined by @file{safe-ctype.h}, and will be an integer constant
+with one of the following values:
+
+@ftable @code
+@item HOST_CHARSET_UNKNOWN
+The host character set is unknown - that is, not one of the next two
+possibilities.
+
+@item HOST_CHARSET_ASCII
+The host character set is ASCII.
+
+@item HOST_CHARSET_EBCDIC
+The host character set is some variant of EBCDIC.  (Only one of the
+nineteen EBCDIC varying characters is tested; exercise caution.)
+@end ftable
+@end defvr
+
+@deffn  Extension ISALPHA  (@var{c})
+@deffnx Extension ISALNUM  (@var{c})
+@deffnx Extension ISBLANK  (@var{c})
+@deffnx Extension ISCNTRL  (@var{c})
+@deffnx Extension ISDIGIT  (@var{c})
+@deffnx Extension ISGRAPH  (@var{c})
+@deffnx Extension ISLOWER  (@var{c})
+@deffnx Extension ISPRINT  (@var{c})
+@deffnx Extension ISPUNCT  (@var{c})
+@deffnx Extension ISSPACE  (@var{c})
+@deffnx Extension ISUPPER  (@var{c})
+@deffnx Extension ISXDIGIT (@var{c})
+
+These twelve macros are defined by @file{safe-ctype.h}.  Each has the
+same meaning as the corresponding macro (with name in lowercase)
+defined by the standard header @file{ctype.h}.  For example,
+@code{ISALPHA} returns true for alphabetic characters and false for
+others.  However, there are two differences between these macros and
+those provided by @file{ctype.h}:
+
+@itemize @bullet
+@item These macros are guaranteed to have well-defined behavior for all 
+values representable by @code{signed char} and @code{unsigned char}, and
+for @code{EOF}.
+
+@item These macros ignore the current locale; they are true for these
+fixed sets of characters:
+@multitable {@code{XDIGIT}} {yada yada yada yada yada yada yada yada}
+@item @code{ALPHA}  @tab @kbd{A-Za-z}
+@item @code{ALNUM}  @tab @kbd{A-Za-z0-9}
+@item @code{BLANK}  @tab @kbd{space tab}
+@item @code{CNTRL}  @tab @code{!PRINT}
+@item @code{DIGIT}  @tab @kbd{0-9}
+@item @code{GRAPH}  @tab @code{ALNUM || PUNCT}
+@item @code{LOWER}  @tab @kbd{a-z}
+@item @code{PRINT}  @tab @code{GRAPH ||} @kbd{space}
+@item @code{PUNCT}  @tab @kbd{`~!@@#$%^&*()_-=+[@{]@}\|;:'",<.>/?}
+@item @code{SPACE}  @tab @kbd{space tab \n \r \f \v}
+@item @code{UPPER}  @tab @kbd{A-Z}
+@item @code{XDIGIT} @tab @kbd{0-9A-Fa-f}
+@end multitable
+
+Note that, if the host character set is ASCII or a superset thereof,
+all these macros will return false for all values of @code{char} outside
+the range of 7-bit ASCII.  In particular, both ISPRINT and ISCNTRL return
+false for characters with numeric values from 128 to 255.
+@end itemize
+@end deffn
+
+@deffn  Extension ISIDNUM         (@var{c})
+@deffnx Extension ISIDST          (@var{c})
+@deffnx Extension IS_VSPACE       (@var{c})
+@deffnx Extension IS_NVSPACE      (@var{c})
+@deffnx Extension IS_SPACE_OR_NUL (@var{c})
+@deffnx Extension IS_ISOBASIC     (@var{c})
+These six macros are defined by @file{safe-ctype.h} and provide
+additional character classes which are useful when doing lexical
+analysis of C or similar languages.  They are true for the following
+sets of characters:
+
+@multitable {@code{SPACE_OR_NUL}} {yada yada yada yada yada yada yada yada}
+@item @code{IDNUM}        @tab @kbd{A-Za-z0-9_}

+@item @code{NVSPACE}      @tab @kbd{space tab \f \v \0}
+@item @code{SPACE_OR_NUL} @tab @code{VSPACE || NVSPACE}

+
+	Using the error_table, which is initialized at compile time, generate
+	the error_names and the sys_errlist (if needed) tables, which are
+	indexed at runtime by a specific errno value.
+
+BUGS
+
+	The initialization of the tables may fail under low memory conditions,
+	in which case we don't do anything particularly useful, but we don't
+	bomb either.  Who knows, it might succeed at a later point if we free
+	some memory in the meantime.  In any case, the other routines know
+	how to deal with lack of a table after trying to initialize it.  This
+	may or may not be considered to be a bug, that we don't specifically
+	warn about this particular failure mode.

+	bomb either.  Who knows, it might succeed at a later point if we free
+	some memory in the meantime.  In any case, the other routines know
+	how to deal with lack of a table after trying to initialize it.  This

+@deftypefun int strverscmp (const char *@var{s1}, const char *@var{s2})
+The @code{strverscmp} function compares the string @var{s1} against
+@var{s2}, considering them as holding indices/version numbers.  Return
+value follows the same conventions as found in the @code{strverscmp}
+function.  In fact, if @var{s1} and @var{s2} contain no digits,
+@code{strverscmp} behaves like @code{strcmp}.
+
+Basically, we compare strings normally (character by character), until
+we find a digit in each string - then we enter a special comparison
+mode, where each sequence of digits is taken as a whole.  If we reach the
+end of these two parts without noticing a difference, we return to the
+standard comparison mode.  There are two types of numeric parts:
+"integral" and "fractional" (those  begin with a '0'). The types
+of the numeric parts affect the way we sort them:
+
+@itemize @bullet
+@item
+integral/integral: we compare values as you would expect.
+
+@item
+fractional/integral: the fractional part is less than the integral one.
+Again, no surprise.
+
+@item
+fractional/fractional: the things become a bit more complex.
+If the common prefix contains only leading zeroes, the longest part is less
+than the other one; else the comparison behaves normally.
+@end itemize
+
+@smallexample
+strverscmp ("no digit", "no digit")
+    @result{} 0    // @r{same behavior as strcmp.}

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+# AM_PROG_INSTALL_STRIP
+# ---------------------
+# One issue with vendor `install' (even GNU) is that you can't
+# specify the program used to strip binaries.  This is especially
+# annoying in cross-compiling environments, where the build's strip
+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in `make install-strip', and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).
+AC_DEFUN([AM_PROG_INSTALL_STRIP],
+[AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
+# Installed binaries are usually stripped using `strip' when the user
+# run `make install-strip'.  However `strip' might not be the right
+# tool to use in cross-compilation environments, therefore Automake
+# will honor the `STRIP' environment variable to overrule this program.
+dnl Don't test for $cross_compiling = yes, because it might be `maybe'.

+\`configure' configures libmudflap 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+			  [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+			  [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
+              headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+

+   (eg. malloc/free, mmap/munmap).
+
+   There are two methods of wrapping.
+
+   (1) The static method involves a list of -wrap=foo flags being passed to
+   the linker, which then links references to "foo" to the symbol
+   "__wrap_foo", and links references to "__real_foo" to the symbol "foo".
+   When compiled without -DPIC, libmudflap.a contains such __wrap_foo
+   functions which delegate to __real_foo functions in libc to get their
+   work done.
+
+   (2) The dynamic method involves providing a definition of symbol foo in
+   libmudflap.so and linking it earlier in the compiler command line,
+   before libc.so. The function "foo" in libmudflap must then call
+   dlsym(RTLD_NEXT, "foo") to acquire a pointer to the "real" libc foo, or
+   at least the "next" foo in the dynamic link resolution order.
+
+   We switch between these two techniques by the presence of the -DPIC
+   #define passed in by libtool when building libmudflap.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.
