+	unless we're being compiled under USG or some other system
+	which already has CPP conditionals saying how to get the time
+	zone offset.
+
+	* getdate.y: Don't divide the Greenwich offset returned by
+	gettimeofday by 60; it's already expressed in minutes, so it
+	doesn't need to be converted.

+	"none of the above" version is last, in the final "else" clause.
+
+	* alloca.c: Do nothing if alloca is defined as a macro.

+	* getopt.c (getopt): If optstring starts with '+', don't
+	permute; this is for utilities like time, nice, xargs, and

+Mon Mar 26 00:36:52 1990  David J. MacKenzie  (djm at spike.ai.mit.edu)
+
+	* getopt.c (getopt): For long-named options that take optional
+	args, never use the next argv-element as an arg; args for
+	these must be part of the same argv-element, separated from
+	the option name by a '='.  This makes them consistent with how
+	short-named options with optional args are handled.
+
+	* getopt.h, getopt.c, getopt1.c: Add some const declarations

+
+Sun Mar  4 12:11:31 1990  Kathy Hargreaves  (kathy at hayley)

+
+	regex.c: (re_compile_pattern): Don't allow empty ranges if the
+	RE_NO_EMPTY_RANGES syntax bit is set.
+	Don't let a hyphen be a range end if the RE_NO_HYPHEN_RANGE_END
+	syntax bit is set.
+	(ESTACK_PUSH_2): renamed this PUSH_FAILURE_POINT and made it
+	push all the used registers on the stack, as well as the number
+	of the highest numbered register used, and (as before) the two
+	failure points.
+	(re_match_2): Fixed up comments.
+	Added arrays best_regstart[], best_regstart_seg1[], best_regend[],
+	and best_regend_seg1[] to keep track of the best match so far
+	whenever reach the end of the pattern but not the end of the
+	string, and there are still failure points on the stack with
+	which to backtrack; if so, do the saving and force a fail.
+	If reach the end of the pattern but not the end of the string,
+	but there are no more failure points to try, restore the best
+	match so far, set the registers and return.
+	Compacted some code.
+	In stop_memory case, if the subexpression we've just left is in
+	a loop, push onto the stack the loop's on_failure_jump failure
+	point along with the current pointer into the string (d).
+	In finalize_jump case, in addition to popping the failure
+	points, pop the saved registers.
+	In the fail case, restore the registers, as well as the failure
+	points.
+
+
+Sun Feb 18 15:08:10 1990  Kathy Hargreaves  (kathy at hayley)
+
+	* regex.c: (global): Defined a macro GET_BUFFER_SPACE which

+	inserting any jumps.
+
+	(re_match_2): Set d to string1 + pos and dend to end_match_1
+	only if string1 isn't null.
+	Force exit from a loop if it's around empty parentheses.
+	In stop_memory case, if found some jumps, increment p2 before
+	extracting address to which to jump. Also, don't need to know
+	how many more times can jump_n.
+	In begline case, d must equal string1 or string2, in that order,
+	only if they are not null.
+	In maybe_finalize_jump case, skip over start_memorys' and
+	stop_memorys' register numbers, too.
+
+Thu Feb 15 15:53:55 1990  Kathy Hargreaves  (kathy at hayley)
+
+	* regex.c (BUFPUSH): off by one goof in deciding whether to

+
+	(re_compile_fastmap): Fixed a bug in succeed_n part where was
+	getting the amount to jump instead of how many times to jump.

+
+	(re_match_2): Moved the comment about duplicate from above the

+	Added commandline arguments to testing.
+
+
+Wed Jan 17 11:47:27 1990  Kathy Hargreaves  (kathy at hayley)
+
+	* regex.c: (global): Defined a macro STORE_NUMBER which stores a
+	number into two contiguous bytes.  Also defined STORE_NUMBER_AND_INCR
+	which does the same thing and then increments the pointer to the
+	storage place to point after the number.
+	Defined a macro EXTRACT_NUMBER which extracts a number from two
+	continguous bytes.  Also defined EXTRACT_NUMBER_AND_INCR which
+	does the same thing and then increments the pointer to the
+	source to point to after where the number was.
+
+
+Tue Jan 16 12:09:19 1990  Kathy Hargreaves  (kathy at hayley)
+
+	* regex.h: Incorporated rms' changes.

+	interpret back reference patterns as literals.
+	Defined RE_NO_EMPTY_BRACKETS syntax bit which is set when want
+	empty bracket expressions to be illegal.
+	Defined RE_CONTEXTUAL_ILLEGAL_OPS syntax bit which is set when want
+	it to be illegal for *, +, ? and { to be first in an re or come
+	immediately after a | or a (, and for ^ not to appear in a
+	nonleading position and $ in a nontrailing position (outside of
+	bracket expressions, that is).
+	Defined RE_LIMITED_OPS syntax bit which is set when want +, ?
+	and | to always be literals instead of ops.
+	Fixed up the Posix syntax.
+	Changed the syntax bit comments from saying, e.g., ``0 means...''
+	to ``If this bit is set, it means...''.
+	Changed the syntax bit defines to use shifts instead of integers.
+
+	* regex.c: (global): Incorporated rms' changes.
+
+	(re_compile_pattern): Incorporated rms' changes
+	Made it illegal for a $ to appear anywhere but inside a bracket
+	expression or at the end of an re when RE_CONTEXTUAL_ILLEGAL_OPS
+	is set. Made the same hold for $ except it has to be at the
+	beginning of an re instead of the end.
+	Made the re "[]" illegal if RE_NO_EMPTY_BRACKETS is set.
+	Made it illegal for | to be first or last in an re, or immediately
+	follow another | or a (.
+	Added and embellished some comments.
+	Allowed \{ to be interpreted as a literal if RE_NO_BK_CURLY_BRACES
+	is set.
+	Made it illegal for *, +, ?, and { to appear first in an re, or

+Thu Dec 21 15:31:32 1989  Kathy Hargreaves  (kathy at hayley)
+
+	* regex.c: (global): Moved RE_DUP_MAX to regex.h and made it
+	equal 2^15 - 1 instead of 1000.
+	Defined NULL to be zero.
+	Moved the definition of BYTEWIDTH to regex.h.
+	Made the global  variable obscure_syntax nonstatic so the tests in
+	another file could use it.
+
+	(re_compile_pattern): Defined a maximum length (CHAR_CLASS_MAX_LENGTH)
+	for character class strings (i.e., what's between the [: and the
+	:]'s).
+	Defined a macro SET_LIST_BIT(c) which sets the bit for C in a
+	character set list.
+	Took out comments that EXTEND_BUFFER clobbers C.
+	Made the string "^" match itself, if not RE_CONTEXT_IND_OPS.
+	Added character classes to bracket expressions.
+	Change the laststart pointer saved with the start of each
+	subexpression to point to start_memory instead of after the
+	following register number.  This is because the subexpression
+	might be in a loop.
+	Added comments and compacted some code.
+	Made intervals only work if preceded by an re matching a single
+	character or a subexpression.
+	Made back references to nonexistent subexpressions illegal if
+	using POSIX syntax.
+	Made intervals work on the last preceding character of a
+	concatenation of characters, e.g., ab{0,} matches abbb, not abab.
+	Moved macro PREFETCH to outside the routine.
+
+	(re_compile_fastmap): Added succeed_n to work analogously to
+	on_failure_jump if n is zero and jump_n to work analogously to
+	the other backward jumps.
+
+	(re_match_2): Defined macro SET_REGS_MATCHED to set which
+	current subexpressions had matches within them.
+	Changed some comments.
+	Added reg_active and reg_matched_something arrays to keep track
+	of in which subexpressions currently have matched something.
+	Defined MATCHING_IN_FIRST_STRING and replaced ``dend == end_match_1''
+	with it to make code easier to understand.
+	Fixed so can apply * and intervals to arbitrarily nested
+	subexpressions.  (Lots of previous bugs here.)
+	Changed so won't match a newline if syntax bit RE_DOT_NOT_NULL is set.
+	Made the upcase array nonstatic so the testing file could use it also.
+
+	(main.c): Moved the tests out to another file.
+
+	(tests.c): Moved all the testing stuff here.
+
+
+Sat Nov 18 19:30:30 1989  Kathy Hargreaves  (kathy at hayley)
+
+	* regex.c: (re_compile_pattern): Defined RE_DUP_MAX, the maximum
+	number of times an interval can match a pattern.
+	Added macro GET_UNSIGNED_NUMBER (used to get below):
+	Added variables lower_bound and upper_bound for upper and lower
+	bounds of intervals.
+	Added variable num_fetches so intervals could do backtracking.
+	Added code to handle '{' and "\{" and intervals.
+	Added to comments.
+
+	(store_jump_n): (Added) Stores a jump with a number following the
+	relative address (for intervals).

+	to obscure syntax to indicate whether or not
+	a syntax handles intervals and recognizes either \{ and
+	\} or { and } as operators.  Also added two syntaxes
+	RE_SYNTAX_POSIX_BASIC and RE_POSIX_EXTENDED and two command codes
+	to the enumeration regexpcode; they are succeed_n and jump_n.
+
+
+Sat Nov 18 19:30:30 1989  Kathy Hargreaves  (kathy at hayley)
+
+	* regex.c: (re_compile_pattern): Defined INIT_BUFF_SIZE to get rid
+	of repeated constants in code.  Tested with value 1.
+	Renamed PATPUSH as BUFPUSH, since it pushes things onto the
+	buffer, not the pattern.  Also made this macro extend the buffer
+	if it's full (so could do the following):
+	Took out code at top of loop that checks to see if buffer is going
+	to be full after 10 additions (and reallocates if necessary).
+
+	(insert_jump): Rearranged declaration lines so comments would read
+	better.
+
+	(re_match_2): Compacted exactn code and added more comments.
+
+	(main): Defined macros TEST_MATCH and MATCH_SELF to do
+	testing; took out loop so could use these instead.

+
+Thu Mar  1 14:10:32 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)
+
+	* getopt.c (getopt): If _getopt_long_only, for options that
+	start with '-' and are not a valid long-named option, only
+	interpret them as short options if the first letter is a valid
+	short option.  Otherwise the error message would be printed
+	naming the short option letter instead of the whole option, and
+	if, for example, there is a 'T' long option, '-Tfoo' would print
+	"prog: invalid option `-T'" (which is wrong).
+

+
+	* getopt.c: Remove all _getopt_option_name stuff.
+	If RETURN_IN_ORDER, return one, not zero, to distinguish between
+	this and a long option.
+
+	* signame.{c,h}: New files.
+
+Tue Feb 27 13:32:45 1990  David J. MacKenzie  (djm at rice-chex)
+
+	* getopt.c (getopt): In RETURN_IN_ORDER mode, set
+	_getopt_option_name to zero when returning a non-option arg in
+	optarg, to distinguish it from getting a long-named option
+	that takes an arg.
+	Print the correct option-introducing character (can be
+	either `+' or `-') in error messages for long-named options.
+	If _getopt_long_only is nonzero, no long options match an
+	option arg that starts with a dash, and there are valid short
+	options, try matching the arg against the short options.

+
+	* obstack.c (_obstack_begin): Use slightly smaller default size

+	to access it.  Programs that refer to the magic number should
+	access it with N_MAGIC (exec), and set it with N_SET_MAGIC (exec,
+	val).  This is a step to having a header that is unambiguous
+	between big and little endian machines.
+
+	* a.out.encap.h: Use macros to access a_info fields.

+Tue Dec 20 14:57:38 1988  Pace Willisson  (pace at prep.at.mit.edu)
+
+	* a.out.gnu.h: Changed exec header to have two bytes
+	(a_machtype and a_flags) instead of a_encap.  a_machtype
+	is the same as on modern sun systems; a_flags can have
+	machine specific flags.  (There may be some endian problems
+	here:  You would like to have the magic number be the
+	first two bytes in the file, and then the next two could
+	be these options.  It looks like the 68000 definitions
+	have to declare the options first to force this to happen.)
+	Defined M_386 for a_machtype.
+	Added definitions for N_DATOFF, N_TRELOFF, N_DRELOFF,
+	N_DATADDR, N_BSSADDR (which are present in sun release 4.0)
+
+	* a.out.encap.h: Defined A_ENCAP as an a_flags value.  Changed
+	uses of a_encap to a_flags & A_ENCAP
+

+
+	* malloc.c: Added functions malloc_mem_used and malloc_mem_free to
+	return total amount of space allocated to program, and total space
+	left in free pool before sbrk must be called.
+
+Tue Nov 22 13:05:25 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)
+
+	* glob.c: Incorporated some bug fixes and changes sent by Brian.
+	None of them look disasterous.
+
+Fri Oct 21 12:40:24 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)
+
+	* malloc.c (free): Added code (within #ifdef rcheck) to given
+	slightly more verbose warnings then an abort if free was called
+	with garbage.

    ANSI C is assumed if __STDC__ is #defined.

-   LONG_DOUBLE	`long double'		`double'

-
-   CONST is also defined, but is obsolete.  Just use const.
-
-   obsolete --     DEFUN (name, arglist, args)
-
-	Defines function NAME.
-
-	ARGLIST lists the arguments, separated by commas and enclosed in
-	parentheses.  ARGLIST becomes the argument list in traditional C.
-
-	ARGS list the arguments with their types.  It becomes a prototype in
-	ANSI C, and the type declarations in traditional C.  Arguments should
-	be separated with `AND'.  For functions with a variable number of
-	arguments, the last thing listed should be `DOTS'.
-
-   obsolete --     DEFUN_VOID (name)
-
-	Defines a function NAME, which takes no arguments.
-
-   obsolete --     EXFUN (name, (prototype))	-- obsolete.
-
-	Replaced by PARAMS.  Do not use; will disappear someday soon.
-	Was used in external function declarations.
-	In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
-	parentheses).  In traditional C it is `NAME()'.
-	For a function that takes no arguments, PROTOTYPE should be `(void)'.
-
-   obsolete --     PROTO (type, name, (prototype)    -- obsolete.
-
-	This one has also been replaced by PARAMS.  Do not use.
-
-   PARAMS ((args))
-
-	We could use the EXFUN macro to handle prototype declarations, but
-	the name is misleading and the result is ugly.  So we just define a
-	simple macro to handle the parameter lists, as in:
-
-	      static int foo PARAMS ((int, char));
-
-	This produces:  `static int foo();' or `static int foo (int, char);'
-
-	EXFUN would have done it like this:
-
-	      static int EXFUN (foo, (int, char));
-
-	but the function is not external...and it's hard to visually parse
-	the function name out of the mess.   EXFUN should be considered
-	obsolete; new code should be written to use PARAMS.
-
-   DOTS is also obsolete.
-
-   Examples:
-
-	extern int printf PARAMS ((const char *format, ...));

+   VA_START(ap, var)	va_start(ap, var)	va_start(ap)
+
+   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.  */

+the presence of a @samp{#line} referring to a different directory.
+
+We made this change because the old behavior caused problems when
+generated source files were transported between machines.  For instance,
+it is common practice to ship generated parsers with a source release,
+so that people building the distribution do not need to have yacc or
+Bison installed.  These files frequently have @samp{#line} directives
+referring to the directory tree of the system where the distribution was
+created.  If GCC tries to search for headers in those directories, the
+build is likely to fail.
+
+The new behavior can cause failures too, if the generated file is not
+in the same directory as its source and it attempts to include a header
+which would be visible searching from the directory containing the
+source file.  However, this problem is easily solved with an additional
+@option{-I} switch on the command line.  The failures caused by the old
+semantics could sometimes be corrected only by editing the generated
+files, which is difficult and error-prone.

+@item @samp{#line} and @samp{#include}
+
+The @samp{#line} directive used to change GCC's notion of the

+@item Syntax of @samp{#line}
+
+In GCC 2.95 and previous, the string constant argument to @samp{#line}
+was treated the same way as the argument to @samp{#include}: backslash
+escapes were not honored, and the string ended at the second @samp{"}.
+This is not compliant with the C standard.  In GCC 3.0, an attempt was
+made to correct the behavior, so that the string was treated as a real
+string constant, but it turned out to be buggy.  In 3.1, the bugs have
+been fixed.  (We are not fixing the bugs in 3.0 because they affect
+relatively few people and the fix is quite invasive.)

-@item -D @var{name}
-Predefine @var{name} as a macro, with definition @code{1}.
-
-@item -D @var{name}=@var{definition}
-Predefine @var{name} as a macro, with definition @var{definition}.
-There are no restrictions on the contents of @var{definition}, but if
-you are invoking the preprocessor from a shell or shell-like program you
-may need to use the shell's quoting syntax to protect characters such as
-spaces that have a meaning in the shell syntax.  If you use more than
-one @option{-D} for the same @var{name}, the rightmost definition takes
-effect.
-
-If you wish to define a function-like macro on the command line, write
-its argument list with surrounding parentheses before the equals sign
-(if any).  Parentheses are meaningful to most shells, so you will need
-to quote the option.  With @command{sh} and @command{csh},
-@option{-D'@var{name}(@var{args@dots{}})=@var{definition}'} works.
-
-@item -U @var{name}
-Cancel any previous definition of @var{name}, either built in or
-provided with a @option{-D} option.
-
-All @option{-imacros @var{file}} and @option{-include @var{file}} options
-are processed after all @option{-D} and @option{-U} options.
-
-@item -undef
-Do not predefine any system-specific macros.  The common predefined
-macros remain defined.
-
-@item -I @var{dir}
-Add the directory @var{dir} to the list of directories to be searched
-for header files.  @xref{Search Path}.  Directories named by @option{-I}
-are searched before the standard system include directories.
-
-It is dangerous to specify a standard system include directory in an
-@option{-I} option.  This defeats the special treatment of system
-headers (@pxref{System Headers}).  It can also defeat the repairs to
-buggy system headers which GCC makes when it is installed.
-
-@item -o @var{file}
-Write output to @var{file}.  This is the same as specifying @var{file}
-as the second non-option argument to @command{cpp}.  @command{gcc} has a
-different interpretation of a second non-option argument, so you must
-use @option{-o} to specify the output file.
-
-@item -Wall
-Turns on all optional warnings which are desirable for normal code.  At
-present this is @option{-Wcomment} and @option{-Wtrigraphs}.  Note that
-many of the preprocessor's warnings are on by default and have no
-options to control them.
-
-@item -Wcomment
-@itemx -Wcomments
-Warn whenever a comment-start sequence @samp{/*} appears in a @samp{/*}
-comment, or whenever a backslash-newline appears in a @samp{//} comment.
-(Both forms have the same effect.)
-
-@item -Wtrigraphs
-Warn if any trigraphs are encountered.  This option used to take effect
-only if @option{-trigraphs} was also specified, but now works
-independently.  Warnings are not given for trigraphs within comments, as
-they do not affect the meaning of the program.
-
-@item -Wtraditional
-Warn about certain constructs that behave differently in traditional and
-ISO C@.  Also warn about ISO C constructs that have no traditional C
-equivalent, and problematic constructs which should be avoided.
-@xref{Traditional Mode}.
-
-@item -Wimport
-Warn the first time @samp{#import} is used.
-
-@item -Wundef
-Warn whenever an identifier which is not a macro is encountered in an
-@samp{#if} directive, outside of @samp{defined}.  Such identifiers are
-replaced with zero.
-
-@item -Werror
-Make all warnings into hard errors.  Source code which triggers warnings
-will be rejected.
-
-@item -Wsystem-headers
-Issue warnings for code in system headers.  These are normally unhelpful
-in finding bugs in your own code, therefore suppressed.  If you are
-responsible for the system library, you may want to see them.
-
-@item -w
-Suppress all warnings, including those which GNU CPP issues by default.
-
-@item -pedantic
-Issue all the mandatory diagnostics listed in the C standard.  Some of
-them are left out by default, since they trigger frequently on harmless
-code.
-
-@item -pedantic-errors
-Issue all the mandatory diagnostics, and make all mandatory diagnostics
-into errors.  This includes mandatory diagnostics that GCC issues
-without @samp{-pedantic} but treats as warnings.
-
-@item -M
-Instead of outputting the result of preprocessing, output a rule
-suitable for @command{make} describing the dependencies of the main
-source file.  The preprocessor outputs one @command{make} rule containing
-the object file name for that source file, a colon, and the names of all
-the included files, including those coming from @option{-include} or
-@option{-imacros} command line options.
-
-Unless specified explicitly (with @option{-MT} or @option{-MQ}), the
-object file name consists of the basename of the source file with any
-suffix replaced with object file suffix.  If there are many included
-files then the rule is split into several lines using @samp{\}-newline.
-The rule has no commands.
-
-@item -MM
-Like @option{-M}, but mention only the files included with @code{@w{#include
-"@var{file}"}} or with @option{-include} or @option{-imacros} command line
-options.  System header files included with @code{@w{#include <@var{file}>}}
-are omitted.
-
-@item -MF @var{file}
-When used with @option{-M} or @option{-MM}, specifies a file to write the
-dependencies to.  This allows the preprocessor to write the preprocessed
-file to stdout normally.  If no @option{-MF} switch is given, CPP sends
-the rules to stdout and suppresses normal preprocessed output.
-
-@item -MG
-When used with @option{-M} or @option{-MM}, @option{-MG} says to treat missing
-header files as generated files and assume they live in the same
-directory as the source file.  It suppresses preprocessed output, as a
-missing header file is ordinarily an error.
-
-This feature is used in automatic updating of makefiles.
-
-@item -MP
-This option instructs CPP to add a phony target for each dependency
-other than the main file, causing each to depend on nothing.  These
-dummy rules work around errors @command{make} gives if you remove header
-files without updating the @file{Makefile} to match.
-
-This is typical output:
-
-@example
-test.o: test.c test.h
-
-test.h:
-@end example
-
-@item -MT @var{target}
-
-Change the target of the rule emitted by dependency generation.  By
-default CPP takes the name of the main input file, including any path,
-deletes any file suffix such as @samp{.c}, and appends the platform's
-usual object suffix.  The result is the target.
-
-An @option{-MT} option will set the target to be exactly the string you
-specify.  If you want multiple targets, you can specify them as a single
-argument to @option{-MT}, or use multiple @option{-MT} options.
-
-For example, @option{@w{-MT '$(objpfx)foo.o'}} might give
-
-@example
-$(objpfx)foo.o: foo.c
-@end example
-
-@item -MQ @var{target}
-
-Same as @option{-MT}, but it quotes any characters which are special to
-Make.  @option{@w{-MQ '$(objpfx)foo.o'}} gives
-
-@example
-$$(objpfx)foo.o: foo.c
-@end example
-
-The default target is automatically quoted, as if it were given with
-@option{-MQ}.
-
-@item -MD @var{file}
-@itemx -MMD @var{file}
-@option{-MD @var{file}} is equivalent to @option{-M -MF @var{file}}, and
-@option{-MMD @var{file}} is equivalent to @option{-MM -MF @var{file}}.
-
-Due to limitations in the compiler driver, you must use these switches
-when you want to generate a dependency file as a side-effect of normal
-compilation.
-
-@item -x c
-@itemx -x c++
-@itemx -x objective-c
-@itemx -x assembler-with-cpp
-Specify the source language: C, C++, Objective-C, or assembly.  This has
-nothing to do with standards conformance or extensions; it merely
-selects which base syntax to expect.  If you give none of these options,
-cpp will deduce the language from the extension of the source file:
-@samp{.c}, @samp{.cc}, @samp{.m}, or @samp{.S}.  Some other common
-extensions for C++ and assembly are also recognized.  If cpp does not
-recognize the extension, it will treat the file as C; this is the most
-generic mode.
-
-@strong{Note:} Previous versions of cpp accepted a @option{-lang} option
-which selected both the language and the standards conformance level.
-This option has been removed, because it conflicts with the @option{-l}
-option.
-
-@item -std=@var{standard}
-@itemx -ansi
-Specify the standard to which the code should conform.  Currently cpp
-only knows about the standards for C; other language standards will be
-added in the future.
-
-@var{standard}
-may be one of:
-@table @code
-@item iso9899:1990
-@itemx c89
-The ISO C standard from 1990.  @samp{c89} is the customary shorthand for

-
-@item -I-
-Split the include path.  Any directories specified with @option{-I}
-options before @option{-I-} are searched only for headers requested with
-@code{@w{#include "@var{file}"}}; they are not searched for
-@code{@w{#include <@var{file}>}}.  If additional directories are
-specified with @option{-I} options after the @option{-I-}, those
-directories are searched for all @samp{#include} directives.
-
-In addition, @option{-I-} inhibits the use of the directory of the current
-file directory as the first search directory for @code{@w{#include
-"@var{file}"}}.  @xref{Search Path}.
-
-@item -nostdinc
-Do not search the standard system directories for header files.
-Only the directories you have specified with @option{-I} options
-(and the directory of the current file, if appropriate) are searched.
-
-@item -nostdinc++
-Do not search for header files in the C++-specific standard directories,
-but do still search the other standard directories.  (This option is
-used when building the C++ library.)
-
-@item -include @var{file}
-
-Process @var{file} as if @code{#include "file"} appeared as the first
-line of the primary source file.  However, the first directory searched
-for @var{file} is the preprocessor's working directory @emph{instead of}
-the directory containing the main source file.  If not found there, it
-is searched for in the remainder of the @code{#include "@dots{}"} search
-chain as normal.
-
-If multiple @option{-include} options are given, the files are included
-in the order they appear on the command line.
-
-@item -imacros @var{file}
-
-Exactly like @option{-include}, except that any output produced by
-scanning @var{file} is thrown away.  Macros it defines remain defined.
-This allows you to acquire all the macros from a header without also
-processing its declarations.
-
-All files specified by @option{-imacros} are processed before all files
-specified by @option{-include}.
-
-@item -idirafter @var{dir}
-Search @var{dir} for header files, but do it @emph{after} all
-directories specified with @option{-I} and the standard system directories
-have been exhausted.  @var{dir} is treated as a system include directory.
-
-@item -iprefix @var{prefix}
-Specify @var{prefix} as the prefix for subsequent @option{-iwithprefix}
-options.  If the prefix represents a directory, you should include the
-final @samp{/}.
-
-@item -iwithprefix @var{dir}
-@itemx -iwithprefixbefore @var{dir}
-
-Append @var{dir} to the prefix specified previously with
-@option{-iprefix}, and add the resulting directory to the include search
-path.  @option{-iwithprefixbefore} puts it in the same place @option{-I}
-would; @option{-iwithprefix} puts it where @option{-idirafter} would.
-
-Use of these options is discouraged.
-
-@item -isystem @var{dir}
-Search @var{dir} for header files, after all directories specified by
-@option{-I} but before the standard system directories.  Mark it
-as a system directory, so that it gets the same special treatment as
-is applied to the standard system directories.  @xref{System Headers}.
-
-@item -fpreprocessed
-Indicate to the preprocessor that the input file has already been
-preprocessed.  This suppresses things like macro expansion, trigraph
-conversion, escaped newline splicing, and processing of most directives.
-The preprocessor still recognizes and removes comments, so that you can
-pass a file preprocessed with @option{-C} to the compiler without
-problems.  In this mode the integrated preprocessor is little more than
-a tokenizer for the front ends.
-
-@option{-fpreprocessed} is implicit if the input file has one of the
-extensions @samp{.i}, @samp{.ii} or @samp{.mi}.  These are the
-extensions that GCC uses for preprocessed files created by
-@option{-save-temps}.
-
-@item -ftabstop=@var{width}
-Set the distance between tab stops.  This helps the preprocessor report
-correct column numbers in warnings or errors, even if tabs appear on the
-line.  If the value is less than 1 or greater than 100, the option is
-ignored.  The default is 8.
-
-@item -fno-show-column
-Do not print column numbers in diagnostics.  This may be necessary if
-diagnostics are being scanned by a program that does not understand the
-column numbers, such as @command{dejagnu}.
-
-@item -A @var{predicate}=@var{answer}
-Make an assertion with the predicate @var{predicate} and answer
-@var{answer}.  This form is preferred to the older form @option{-A
-@var{predicate}(@var{answer})}, which is still supported, because
-it does not use shell special characters.  @xref{Assertions}.
-
-@item -A -@var{predicate}=@var{answer}
-Cancel an assertion with the predicate @var{predicate} and answer
-@var{answer}.
-
-@item -A-
-Cancel all predefined assertions and all assertions preceding it on
-the command line.  Also, undefine all predefined macros and all
-macros preceding it on the command line.  (This is a historical wart and
-may change in the future.)
-
-@item -dCHARS
-@var{CHARS} is a sequence of one or more of the following characters,
-and must not be preceded by a space.  Other characters are interpreted
-by the compiler proper, or reserved for future versions of GCC, and so
-are silently ignored.  If you specify characters whose behavior
-conflicts, the result is undefined.
-
-@table @samp
-@item M
-Instead of the normal output, generate a list of @samp{#define}
-directives for all the macros defined during the execution of the
-preprocessor, including predefined macros.  This gives you a way of
-finding out what is predefined in your version of the preprocessor.
-Assuming you have no file @file{foo.h}, the command
-
-@example
-touch foo.h; cpp -dM foo.h
-@end example
-
-@noindent
-will show all the predefined macros.
+@include cppopts.texi
+@c man end
 
-@item D
-Like @samp{M} except in two respects: it does @emph{not} include the
-predefined macros, and it outputs @emph{both} the @samp{#define}
-directives and the result of preprocessing.  Both kinds of output go to
-the standard output file.
+@node Environment Variables
+@chapter Environment Variables
+@cindex environment variables
+@c man begin ENVIRONMENT
 
-@item N
-Like @samp{D}, but emit only the macro names, not their expansions.
+This section describes the environment variables that affect how CPP
+operates.  You can use them to specify directories or prefixes to use
+when searching for include files, or to control dependency output.
 
-@item I
-Output @samp{#include} directives in addition to the result of
-preprocessing.
-@end table
+Note that you can also specify places to search using options such as
+@option{-I}, and control dependency output with options like
+@option{-M} (@pxref{Invocation}).  These take precedence over
+environment variables, which in turn take precedence over the
+configuration of GCC@.
 
-@item -P
-Inhibit generation of linemarkers in the output from the preprocessor.
-This might be useful when running the preprocessor on something that is
-not C code, and will be sent to a program which might be confused by the
-linemarkers.  @xref{Preprocessor Output}.
-
-@item -C
-Do not discard comments.  All comments are passed through to the output
-file, except for comments in processed directives, which are deleted
-along with the directive.
-
-You should be prepared for side effects when using @option{-C}; it
-causes the preprocessor to treat comments as tokens in their own right.
-For example, comments appearing at the start of what would be a
-directive line have the effect of turning that line into an ordinary
-source line, since the first token on the line is no longer a @samp{#}.
-
-@item -gcc
-Define the macros @sc{__gnuc__}, @sc{__gnuc_minor__} and
-@sc{__gnuc_patchlevel__}.  These are defined automatically when you use
-@command{gcc -E}; you can turn them off in that case with
-@option{-no-gcc}.
-
-@item -traditional
-Try to imitate the behavior of old-fashioned C, as opposed to ISO
-C@.  @xref{Traditional Mode}.
-
-@item -trigraphs
-Process trigraph sequences.  @xref{Initial processing}.
-
-@item -remap
-Enable special code to work around file systems which only permit very
-short file names, such as MS-DOS@.
-
-@item -$
-Forbid the use of @samp{$} in identifiers.  The C standard allows
-implementations to define extra characters that can appear in
-identifiers.  By default GNU CPP permits @samp{$}, a common extension.
-
-@item -h
-@itemx --help
-@itemx --target-help
-Print text describing all the command line options instead of
-preprocessing anything.
-
-@item -v
-Verbose mode.  Print out GNU CPP's version number at the beginning of
-execution, and report the final form of the include path.
-
-@item -H
-Print the name of each header file used, in addition to other normal
-activities.  Each name is indented to show how deep in the
-@samp{#include} stack it is.

+@c @itemx OBJCPLUS_INCLUDE_PATH
+Each variable's value is a list of directories separated by a special
+character, much like @env{PATH}, in which to look for header files.
+The special character, @code{PATH_SEPARATOR}, is target-dependent and
+determined at GCC build time.  For Windows-based targets it is a
+semicolon, and for almost all other targets it is a colon.
+
+@env{CPATH} specifies a list of directories to be searched as if
+specified with @option{-I}, but after any paths given with @option{-I}
+options on the command line.  The environment variable is used
+regardless of which language is being preprocessed.
+
+The remaining environment variables apply only when preprocessing the

+See also @ref{Search Path}.

+@anchor{DEPENDENCIES_OUTPUT}
+@cindex dependencies for make as output
+If this variable is set, its value specifies how to output
+dependencies for Make based on the non-system header files processed
+by the compiler.  System header files are ignored in the dependency
+output.
+
+The value of @env{DEPENDENCIES_OUTPUT} can be just a file name, in

+name from the source file name.  Or the value can have the form
+@samp{@var{file} @var{target}}, in which case the rules are written to
+file @var{file} using @var{target} as the target name.
+
+In other words, this environment variable is equivalent to combining

+Turns on all optional warnings which are desirable for normal code.  At

+
+@item -Wcomment

+@opindex Wcomment
+@opindex Wcomments

+(Both forms have the same effect.)
+
+@item -Wtrigraphs
+@opindex Wtrigraphs
+Warn if any trigraphs are encountered.  This option used to take effect
+only if @option{-trigraphs} was also specified, but now works
+independently.  Warnings are not given for trigraphs within comments, as
+they do not affect the meaning of the program.
+
+@item -Wtraditional

+
+@item -Werror
+@opindex Werror
+Make all warnings into hard errors.  Source code which triggers warnings
+will be rejected.
+
+@item -Wsystem-headers
+@opindex Wsystem-headers
+Issue warnings for code in system headers.  These are normally unhelpful
+in finding bugs in your own code, therefore suppressed.  If you are
+responsible for the system library, you may want to see them.
+
+@item -w
+@opindex w
+Suppress all warnings, including those which GNU CPP issues by default.
+
+@item -pedantic
+@opindex pedantic
+Issue all the mandatory diagnostics listed in the C standard.  Some of
+them are left out by default, since they trigger frequently on harmless
+code.
+
+@item -pedantic-errors
+@opindex pedantic-errors
+Issue all the mandatory diagnostics, and make all mandatory diagnostics
+into errors.  This includes mandatory diagnostics that GCC issues
+without @samp{-pedantic} but treats as warnings.
+
+@item -M
+@opindex M
+@cindex make
+@cindex dependencies, make
+Instead of outputting the result of preprocessing, output a rule
+suitable for @command{make} describing the dependencies of the main
+source file.  The preprocessor outputs one @command{make} rule containing
+the object file name for that source file, a colon, and the names of all
+the included files, including those coming from @option{-include} or
+@option{-imacros} command line options.
+
+Unless specified explicitly (with @option{-MT} or @option{-MQ}), the
+object file name consists of the basename of the source file with any
+suffix replaced with object file suffix.  If there are many included
+files then the rule is split into several lines using @samp{\}-newline.
+The rule has no commands.
+
+This option does not suppress the preprocessor's debug output, such as
+@option{-dM}.  To avoid mixing such debug output with the dependency
+rules you should explicitly specify the dependency output file with
+@option{-MF}, or use an environment variable like
+@env{DEPENDENCIES_OUTPUT} (@pxref{DEPENDENCIES_OUTPUT}).  Debug output
+will still be sent to the regular output stream as normal.
+
+Passing @option{-M} to the driver implies @option{-E}.
+
+@item -MM
+@opindex MM
+Like @option{-M} but do not mention header files that are found in
+system header directories, nor header files that are included,
+directly or indirectly, from such a header.
+
+This implies that the choice of angle brackets or double quotes in an
+@samp{#include} directive does not in itself determine whether that
+header will appear in @option{-MM} dependency output.  This is a
+slight change in semantics from GCC versions 3.0 and earlier.
+
+@item -MF @var{file}
+@opindex MF
+@anchor{-MF}
+When used with @option{-M} or @option{-MM}, specifies a
+file to write the dependencies to.  If no @option{-MF} switch is given
+the preprocessor sends the rules to the same place it would have sent
+preprocessed output.
+
+When used with the driver options @option{-MD} or @option{-MMD},
+@option{-MF} overrides the default dependency output file.
+
+@item -MG
+@opindex MG
+When used with @option{-M} or @option{-MM}, @option{-MG} says to treat missing
+header files as generated files and assume they live in the same
+directory as the source file.  It suppresses preprocessed output, as a
+missing header file is ordinarily an error.
+
+This feature is used in automatic updating of makefiles.
+
+@item -MP
+@opindex MP
+This option instructs CPP to add a phony target for each dependency
+other than the main file, causing each to depend on nothing.  These
+dummy rules work around errors @command{make} gives if you remove header
+files without updating the @file{Makefile} to match.
+
+This is typical output:
+
+@example
+test.o: test.c test.h
+
+test.h:
+@end example
+
+@item -MT @var{target}
+@opindex MT
+
+Change the target of the rule emitted by dependency generation.  By
+default CPP takes the name of the main input file, including any path,
+deletes any file suffix such as @samp{.c}, and appends the platform's
+usual object suffix.  The result is the target.
+
+An @option{-MT} option will set the target to be exactly the string you
+specify.  If you want multiple targets, you can specify them as a single
+argument to @option{-MT}, or use multiple @option{-MT} options.
+
+For example, @option{@w{-MT '$(objpfx)foo.o'}} might give
+
+@example
+$(objpfx)foo.o: foo.c
+@end example
+
+@item -MQ @var{target}
+@opindex MQ
+
+Same as @option{-MT}, but it quotes any characters which are special to
+Make.  @option{@w{-MQ '$(objpfx)foo.o'}} gives
+
+@example
+$$(objpfx)foo.o: foo.c
+@end example
+
+The default target is automatically quoted, as if it were given with
+@option{-MQ}.
+
+@item -MD
+@opindex MD
+@option{-MD} is equivalent to @option{-M -MF @var{file}}, except that
+@option{-E} is not implied.  The driver determines @var{file} based on
+whether an @option{-o} option is given.  If it is, the driver uses its
+argument but with a suffix of @file{.d}, otherwise it take the
+basename of the input file and applies a @file{.d} suffix.
+
+If @option{-MD} is used in conjunction with @option{-E}, any
+@option{-o} switch is understood to specify the dependency output file
+(but @pxref{-MF}), but if used without @option{-E}, each @option{-o}
+is understood to specify a target object file.
+
+Since @option{-E} is not implied, @option{-MD} can be used to generate
+a dependency output file as a side-effect of the compilation process.
+
+@item -MMD
+@opindex MMD
+Like @option{-MD} except mention only user header files, not system
+-header files.
+
+@item -x c
+@itemx -x c++
+@itemx -x objective-c
+@itemx -x assembler-with-cpp
+@opindex x
+Specify the source language: C, C++, Objective-C, or assembly.  This has
+nothing to do with standards conformance or extensions; it merely
+selects which base syntax to expect.  If you give none of these options,
+cpp will deduce the language from the extension of the source file:
+@samp{.c}, @samp{.cc}, @samp{.m}, or @samp{.S}.  Some other common
+extensions for C++ and assembly are also recognized.  If cpp does not
+recognize the extension, it will treat the file as C; this is the most
+generic mode.
+
+@strong{Note:} Previous versions of cpp accepted a @option{-lang} option
+which selected both the language and the standards conformance level.
+This option has been removed, because it conflicts with the @option{-l}
+option.
+
+@item -std=@var{standard}
+@itemx -ansi
+@opindex ansi
+@opindex std=
+Specify the standard to which the code should conform.  Currently cpp
+only knows about the standards for C; other language standards will be
+added in the future.
+
+@var{standard}
+may be one of:
+@table @code
+@item iso9899:1990
+@itemx c89
+The ISO C standard from 1990.  @samp{c89} is the customary shorthand for
+this version of the standard.

+The @option{-ansi} option is equivalent to @option{-std=c89}.
+

+The 1990 C standard, as amended in 1994.
+

+specified with @option{-I} options after the @option{-I-}, those
+directories are searched for all @samp{#include} directives.
+
+In addition, @option{-I-} inhibits the use of the directory of the current

+Only the directories you have specified with @option{-I} options
+(and the directory of the current file, if appropriate) are searched.
+
+@item -nostdinc++
+@opindex nostdinc++
+Do not search for header files in the C++-specific standard directories,
+but do still search the other standard directories.  (This option is
+used when building the C++ library.)
+
+@item -include @var{file}
+@opindex include
+Process @var{file} as if @code{#include "file"} appeared as the first
+line of the primary source file.  However, the first directory searched
+for @var{file} is the preprocessor's working directory @emph{instead of}
+the directory containing the main source file.  If not found there, it
+is searched for in the remainder of the @code{#include "@dots{}"} search
+chain as normal.
+
+If multiple @option{-include} options are given, the files are included
+in the order they appear on the command line.
+
+@item -imacros @var{file}
+@opindex imacros
+Exactly like @option{-include}, except that any output produced by
+scanning @var{file} is thrown away.  Macros it defines remain defined.
+This allows you to acquire all the macros from a header without also
+processing its declarations.
+
+All files specified by @option{-imacros} are processed before all files
+specified by @option{-include}.
+
+@item -idirafter @var{dir}
+@opindex idirafter
+Search @var{dir} for header files, but do it @emph{after} all
+directories specified with @option{-I} and the standard system directories
+have been exhausted.  @var{dir} is treated as a system include directory.
+
+@item -iprefix @var{prefix}
+@opindex iprefix
+Specify @var{prefix} as the prefix for subsequent @option{-iwithprefix}
+options.  If the prefix represents a directory, you should include the

+
+@item -iwithprefix @var{dir}
+@itemx -iwithprefixbefore @var{dir}
+@opindex iwithprefix
+@opindex iwithprefixbefore
+Append @var{dir} to the prefix specified previously with
+@option{-iprefix}, and add the resulting directory to the include search
+path.  @option{-iwithprefixbefore} puts it in the same place @option{-I}
+would; @option{-iwithprefix} puts it where @option{-idirafter} would.
+
+Use of these options is discouraged.
+
+@item -isystem @var{dir}
+@opindex isystem
+Search @var{dir} for header files, after all directories specified by
+@option{-I} but before the standard system directories.  Mark it
+as a system directory, so that it gets the same special treatment as
+is applied to the standard system directories.
+@ifset cppmanual

+@end ifset
+
+@item -fpreprocessed
+@opindex fpreprocessed
+Indicate to the preprocessor that the input file has already been
+preprocessed.  This suppresses things like macro expansion, trigraph
+conversion, escaped newline splicing, and processing of most directives.
+The preprocessor still recognizes and removes comments, so that you can
+pass a file preprocessed with @option{-C} to the compiler without
+problems.  In this mode the integrated preprocessor is little more than
+a tokenizer for the front ends.
+
+@option{-fpreprocessed} is implicit if the input file has one of the
+extensions @samp{.i}, @samp{.ii} or @samp{.mi}.  These are the
+extensions that GCC uses for preprocessed files created by
+@option{-save-temps}.
+
+@item -ftabstop=@var{width}
+@opindex ftabstop
+Set the distance between tab stops.  This helps the preprocessor report
+correct column numbers in warnings or errors, even if tabs appear on the
+line.  If the value is less than 1 or greater than 100, the option is
+ignored.  The default is 8.
+
+@item -fno-show-column
+@opindex fno-show-column
+Do not print column numbers in diagnostics.  This may be necessary if
+diagnostics are being scanned by a program that does not understand the
+column numbers, such as @command{dejagnu}.
+
+@item -A @var{predicate}=@var{answer}
+@opindex A
+Make an assertion with the predicate @var{predicate} and answer
+@var{answer}.  This form is preferred to the older form @option{-A
+@var{predicate}(@var{answer})}, which is still supported, because
+it does not use shell special characters.
+@ifset cppmanual
+@xref{Assertions}.

+Cancel an assertion with the predicate @var{predicate} and answer
+@var{answer}.
+
+@item -A-
+@opindex A-
+Cancel all predefined assertions and all assertions preceding it on
+the command line.  Also, undefine all predefined macros and all
+macros preceding it on the command line.  (This is a historical wart and
+may change in the future.)
+
+@item -dCHARS
+@var{CHARS} is a sequence of one or more of the following characters,
+and must not be preceded by a space.  Other characters are interpreted
+by the compiler proper, or reserved for future versions of GCC, and so
+are silently ignored.  If you specify characters whose behavior
+conflicts, the result is undefined.
+
+@table @samp
+@item M
+@opindex dM
+Instead of the normal output, generate a list of @samp{#define}
+directives for all the macros defined during the execution of the
+preprocessor, including predefined macros.  This gives you a way of
+finding out what is predefined in your version of the preprocessor.
+Assuming you have no file @file{foo.h}, the command
+
+@example
+touch foo.h; cpp -dM foo.h
+@end example
+
+@noindent
+will show all the predefined macros.
+
+@item D
+@opindex dD
+Like @samp{M} except in two respects: it does @emph{not} include the
+predefined macros, and it outputs @emph{both} the @samp{#define}
+directives and the result of preprocessing.  Both kinds of output go to
+the standard output file.
+
+@item N

+Do not discard comments.  All comments are passed through to the output
+file, except for comments in processed directives, which are deleted
+along with the directive.
+
+You should be prepared for side effects when using @option{-C}; it
+causes the preprocessor to treat comments as tokens in their own right.
+For example, comments appearing at the start of what would be a
+directive line have the effect of turning that line into an ordinary
+source line, since the first token on the line is no longer a @samp{#}.
+
+@item -gcc
+@opindex gcc
+Define the macros @sc{__gnuc__}, @sc{__gnuc_minor__} and
+@sc{__gnuc_patchlevel__}.  These are defined automatically when you use
+@command{gcc -E}; you can turn them off in that case with
+@option{-no-gcc}.

+@end ifset
+@ifclear cppmanual
+These are three-character sequences, all starting with @samp{??}, that
+are defined by ISO C to stand for single characters.  For example,
+@samp{??/} stands for @samp{\}, so @samp{'??/n'} is a character
+constant for a newline.  By default, GCC ignores trigraphs, but in
+standard-conforming modes it converts them.  See the @option{-std} and
+@option{-ansi} options.
+
+The nine trigraphs and their replacements are
+
+@example
+Trigraph:       ??(  ??)  ??<  ??>  ??=  ??/  ??'  ??!  ??-

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o # or whatever, to process the dvi file; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages.  You can get
+% the existing language-specific files from the full Texinfo distribution.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+%
+% For those who want to use more than one line's worth of words in
+% the preamble, break the line within one argument and it
+% will parse correctly, i.e.,
+%
+%     @multitable {Column 1 template} {Column 2 template} {Column 3
+%      template}
+% Not:
+%     @multitable {Column 1 template} {Column 2 template}
+%      {Column 3 template}
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab, @multitable or @end multitable do not need to be on their
+% own lines, but it will not hurt if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.
+%   0pt means it depends on current normal line spacing.

+In principle, @option{--enable-threads} is now compatible with

+and tested on i386-*-freebsd4.5 and alpha-*-freebsd5.0.  The static
+library may be incorrectly built (symbols are missing at link time).
+There is a rare timing-based startup hang (probably involves an
+assupmtion about the thread library).  Multi-threaded boehm-gc (required for
+libjava) exposes severe threaded signal-handling bugs on FreeBSD before
+4.5-RELEASE.  The alpha port may not fully bootstrap without some manual
+intervention: gcjh will crash with a floating-point exception while
+generating @file{java/lang/Double.h} (just copy the version built on
+i386-*-freebsd* and rerun the top-level gmake with no arguments and it
+should properly complete the bootstrap).  Other CPU architectures
+supported by FreeBSD will require additional configuration tuning in, at
+the very least, both boehm-gc and libffi.

-target for dependency generation.  With @option{-MT} you can specify a
-target yourself, overriding the default one.
-
-If you want multiple targets, you can specify them as a single argument
-to @option{-MT}, or use multiple @option{-MT} options.
-
-The targets you specify are output in the order they appear on the
-command line.  @option{-MQ} is identical to @option{-MT}, except that the
-target name is quoted for Make, but with @option{-MT} it isn't.  For

+/* Windows32 threads specific definitions. The windows32 threading model
+   does not map well into pthread-inspired gcc's threading model, and so 
+   there are caveats one needs to be aware of.
+
+   1. The destructor supplied to __gthread_key_create is ignored for
+      generic x86-win32 ports. This will certainly cause memory leaks 
+      due to unreclaimed eh contexts (sizeof (eh_context) is at least 
+      24 bytes for x86 currently).
+
+      This memory leak may be significant for long-running applications
+      that make heavy use of C++ EH.
+
+      However, Mingw runtime (version 0.3 or newer) provides a mechanism
+      to emulate pthreads key dtors; the runtime provides a special DLL,
+      linked in if -mthreads option is specified, that runs the dtors in
+      the reverse order of registration when each thread exits. If
+      -mthreads option is not given, a stub is linked in instead of the
+      DLL, which results in memory leak. Other x86-win32 ports can use 
+      the same technique of course to avoid the leak.
+
+   2. The error codes returned are non-POSIX like, and cast into ints.
+      This may cause incorrect error return due to truncation values on 
+      hw where sizeof (DWORD) > sizeof (int).
+   
+   3. We might consider using Critical Sections instead of Windows32 
+      mutexes for better performance, but emulating __gthread_mutex_trylock 
+      interface becomes more complicated (Win9x does not support
+      TryEnterCriticalSectioni, while NT does).
+  
+   The basic framework should work well enough. In the long term, GCC
+   needs to use Structured Exception Handling on Windows32.  */

+
+   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.  */
