+
+Thu Apr 19 16:21:56 2001  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* random.h: Move decl of random() here.
+	* random.c: Remove decl of random().
+
+Mon Apr  9 11:41:58 2001  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* dfa.c (dfainit): Initialize more members in the structure,
+	  based on bug report in bug.gnu.utils by aaronl@vitelus.com
+	  (Aaron Lehmann).
+	* awk.h: Fix logic around include of <sys/types.h>.

+
+	* builtin.c (do_mktime): Allow the user to specify the
+          tm_isdst member as an optional trailing integer, and to
+          specify "out-of-range" members.  Check for overflow when
+          subtracting 1 from month or 1900 from year.  Allow years just
+          past INT_MAX, as they work on some hosts when INT_MAX - 1900
+          is representable as an int.
+
+	* doc/gawk.1, doc/gawk.texi: Document the above changes.
+	  Also, document that the origin-zero Gregorian calendar is used.
+	  Fix confusing wording about "midnight" by replacing it with 00:00

+	  Mention the typical range for time stamps.
+	  Do not assume that years are nonnegative and are less than 10,000.
+	  Suggest TZ=UTC0 instead of TZ=GMT0, as that's how recent versions
+	  of GNU date behave.
+	  GMT is not always the time of day in Greenwich these days.
+	  Fix typos: "Emporer/Era", "1980's", "1970's".
+
+	* m4/largefile.m4: Synchronized with latest version.

+
+	* awkgram.y (LEX_FOR): Allow newline after `;' in for loops.

+
+	* io.c (socket_open): Conditionalize various options based on
+	  ifdef. Needed for BeOS port.
+
+Tue Feb  6 18:17:13 2001  Michal Jaegermann  <michal@ellpspace.math.ualberta.ca>
+
+	* regex.c (re_match_2_internal): Case maybe_pop_jump, for
+	  charset and not_charset: change cast from (unsigned char)
+          to (unsigned).  Catches last 8 chars with high bit set
+	  if backtracking. See test/rebt8b1.awk, test/rebt8b2.awk.
+
+Tue Feb  6 11:20:21 2001  Arnold D. Robbins  <arnold@skeeve.com>

+Sun Jan 28 16:16:02 2001  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Per request from Nelson Beebe, SIGHUP to pgawk dumps profile

+	* builtin.c (do_dcgettext): Improve ifdef for code, fixes MacOS X.
+	* custom.h (__APPLE__): Force definition of HAVE_MKTIME, won't
+	  link otherwise.  Harumph.
+

+
+	* builtin.c (do_dcgettext, do_bindtextdomain): Add calls to

+
+	* builtin.c (parse_next_arg): Fix call to >= num_args so
+	  running out of args check is correct, instead of core dumping.
+	  (format_tree): Save and restore `the_args' and `args_size'
+	  if a nested call is in progress, see explanatory comment.
+	  See also tests/addcomma.
+	* Makefile.am: Fix things so that gawk/pgawk built first,
+	  even if `make check' called before make.  Add some
+	  commentary.
+
+Wed Nov  8 14:39:20 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* configure.in: Only add -rdynamic for linux.

+
+Tue Nov  7 16:57:49 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (redirect): Check for O_APPEND in flags when doing
+	  fdopen() of /dev/fd/N.  Thanks to bug report from
+	  "John H. DuBois III" <spcecdt@armory.com>.
+
+Tue Nov  7 14:09:14 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h (os_is_setuid): declare function.
+	* main.c (main): call it if do_lint and warn if true.
+	* awkgram.y (tokentab):

+	  from glibc CVS archive.
+
+Mon Nov  6 18:14:33 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* random.c: Replaced with recent version from FreeBSD.

+
+Tue Oct 17 10:47:35 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* array.c (assoc_lookup): Reverted change that did dupnode of
+	  array indices.  Creates significant problems if index is
+	  numeric value and CONVFMT changes.  Added fix to set
+	  bucket->ahname->stfmt to -1 so that force_string never recalculates
+	  the string value, and also turned off NUM and turned on STR.
+	  See test/arynasty.awk.
+
+Mon Oct 16 12:21:26 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* All: Cleaned up various lint warnings for consistent phrasing.
+	* awk.y (in_end_rule): New variable for warning about unredirected

+
+	* field.c (set_FS): Add lint warning for FS = "".

+
+Fri Oct 13 09:17:04 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (close_redir): Clear rp->fp on all closes.  Remove
+	  rp from list if either closing both ends or both ends
+	  have been closed separately. Add exitwarn message for
+	  co-process.
+	  (flush_io): Add warning message if fflush of co-process
+	  fails.  Rationalize return value to either 0 or -1.
+	* builtin.c (do_gensub): 3rd arg of zero generates a
+	  warning.
+	  (do_fflush): rationalize return value: -1 for unopen or read-only
+	  redirection, status of fflush otherwise.

+
+	* awk.y (for loop): Check that there is a body as

+
+Thu Oct  5 11:56:42 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h, awkgram.y, configure.in, eval.c: enabled

+
+	* io.c (do_close): make close(x) for non-open x return -1
+	  and update ERRNO.  close(FILENAME) no longer does anything
+	  magic; this is all for better consistency with other awks
+	  and is more logical, anyway.
+
+Thu Sep 28 17:27:16 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (close_one): Added a lint warning if it becomes
+	  necessary to start multiplexing fd's, per ancient suggestion
+	  from Scott Deifik, <scottd@amgen.com>.
+
+Tue Sep 26 14:41:41 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* profile.c: Move enum for redirection placement to top
+	  of file, and make the value a parameter to pp_redir.
+	  Fix all the calls.  This gets `|&' right everywhere.
+
+Sun Sep 24 16:38:04 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h (freenode): set the flags straight to UNINITIALIZED.
+	* node.c (unref): Fix test for MALLOC|TEMP to test the
+	  actual flags, not zero.
+	* builtin.c (format_tree): ala print and concat, dupnode
+	  the temp nodes from tree_evaling the arguments.  See
+	  test/nasty2.awk.
+
+Mon Sep 18 10:16:58 2000  Arnold D. Robbins  <arnold@skeeve.com>

+Sun Aug 13 11:10:41 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Changes from Alan J. Broder (ajb@woti.com):
+	- Array third arg to match puts subtexts into the array:
+	* awk.y (tokentab): "match" gets third arg, and lint warning
+	* builtin.c (do_match): if third arg there, fill it with subtexts
+	- New builtin sort function:
+	* awk.h (do_sort): declared.
+	* array.c (do_sort, dup_table, merge, merge_sort, assoc_from_list,
+	  assoc_sort_inplace): new functions.
+
+	* eval.c (tree_eval): in debug code, make uninitialized var

+
+Wed Aug  9 10:51:41 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (func_call): Increment the exec_count on the
+	  function's node; this allows printing a call count for
+	  functions.
+	  profile.c (pp_func): print the count for functions.
+	* ALL: Changed DEBUG to GAWKDEBUG in all gawk files, so that
+	  I don't get regex/dfa debugging.  In some cases, changed
+	  memory-related stuff to MEMDEBUG.  Still have work to do.
+	* awk.h, node.c, profile.c: removed exec_count_init variable;
+	  code has been cleaned up to not need different values for
+	  profiling/not profiling.
+	
+Thu Jul  5 21:10:59 2000  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (casetable): Removed the USE_PURE_ASCII stuff; it
+	  was never documented.  Latin 1 forever.
+	* main.c (main): only call `init_profiling' after arg parsing
+	  if `do_profiling' is still false.  Avoids resetting `prof_fp'
+	  back to stderr.
+
+2000-02-17  Akim Demaille  <akim@epita.fr>

+
+2000-02-15  Arnold Robbins  <arnold@skeeve.com>

+	* Makefile.in: changes to only recompile eval.c and profile.c to a
+	  special version for profiling.
+	* custom.h [MSC_VER]: turn on NO_PROFILING to omit the exec_count
+	  and save space.
+	* node.c (more_nodes): move setting of exec_count to
+	  #ifndef NO_PROFILING.
+
+Thu Jul  1 12:12:05 1999  Arnold D. Robbins  <arnold@skeeve.com>
+

+	  > and >>.
+
+Thu Apr 22 15:05:30 1999  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* array.c (assoc_lookup): Fix call to fatal to lintwarn instead.
+	* node.c (r_force_number): Use `0 &&' to disable warnings about
+	  conversions: they're overzealous, methinks.
+
+Thu Apr  8 14:27:58 1999  Arnold D. Robbins  <arnold@skeeve.com>
+
+	  New features for profiling:

+
+Wed Mar 10 21:38:14 1999  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (close_redir): use update_ERRNO() instead of manually
+	  doing it.
+
+Mon Dec 21 15:58:21 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* configure.in: add BeOS to list of cases where we hardwire
+	  GETPGRP_VOID.
+	  custom.h: remove the #define from __be_os case. Cleaner to
+	  do it all in configure. Based on email from Martin C. Brown,
+	  mc@whoever.com.
+
+Mon Nov 30 20:52:52 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (update_ERRNO): new function, mainly for use by
+	  extension functions.

+
+	* Changes based on submission from Christos Zoulas at D.E. Shaw
+	  that adds the following features:

+	  - ability to load a dynamic library to add built-ins
+	  - VERSION variable (may or may not stay)
+	  Additional change:

+
+Sat Nov  7 21:29:52 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (r_get_lhs): case Node_field_spec.  Fix the lint
+	  warnings for field reference of null string or non-numeric value.
+	  When turned on, $0 generated a warning!  Oops.
+
+Thu Nov  5 16:58:38 1998 Arnold D. Robbins  <arnold@skeeve.com>
+
+	* main.c (init_fds): new function to pre-open 0, 1, and 2 on

+
+	* builtin.c (do_*): added lint checks for non-numeric
+	  and/or non-string arguments, as appropriate. This should
+	  have been done long ago.

+
+	* awk.h (LINT_node): new variable for LINT special var

+
+Sun Sep 27 10:18:05 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h (reisstring): new prototype.
+	* re.c (reisstring): new function, returns true if the re did
+	  a simple string match. This is rather simplistic in its logic.
+	* io.c (get_a_record): in the case that RS is a regexp, AND
+	  the re matched at the exact end of the buffer, add a call to
+	  `reisstring' in case it's a simple string match. If so, we
+	  don't need to read more into the buffer because we don't
+	  have a regex like `x.*y' that might extend longer.
+	  This should be very helpful for interactive /inet clients
+	  where something like `RS = "\r\n"' happens.
+
+Thu Aug 13 22:07:40 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (socketopen): fixes from Juergen Kahrs to socket

+
+	* aclocal.m4 (GAWK_AC_LIB_SOCKETS): removed the caching;
+	  configure gave different results the second time it was run!
+
+Fri Jul 10 09:11:06 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* eval.c (interpret): minor cleanups: add variable name to

+
+Mon Jun 22 16:53:34 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* Makefile.in (tags, TAGS): add $(LIBSRC).
+
+Tue Jun  2 15:23:05 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (devopen): relax previous change, don't require "any",
+	  just that a port be there. The user can put 0 if they
+	  don't care.
+
+Wed May 27 21:33:45 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* io.c (devopen): for /inet, require that local and remote
+	  ports and the remote hostname be there, and that `any'
+	  be used for a port if they don't care.
+
+Thu May 21 14:13:46 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* node.c (parse_escape): Add warning that is always on
+	  for \q for any unknown q inside string or regex constant.
+	  I got bit by this myself once too often. Or else I'm
+	  just getting old and senile.
+
+Mon May  4 12:42:49 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h (NODETYPE): Sorted the Node_xxx entries for the
+	  builtin variables. Gotta look nice, don't we?
+	* eval.c (nodetypes): ditto.
+	  (genflags2str): added code to check that we don't
+	  overflow the static buffer. This is just a debugging
+	  routine, not worth the hassle of dynamic allocation.
+
+Mon Mar  2 16:06:16 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* Makefile.in (dist): remove any embedded copied RCS or CVS
+	  directories.
+
+Mon Feb 23 00:09:52 1998  Arnold D. Robbins  <arnold@skeeve.com>
+
+	* awk.h (genflags2str): add declaration.
+	* eval.c (genflags2str): new function.

+	  (redirect): better error message in default case, add code for
+	  Node_redirect_twoway.
