Tue Jul 26 21:46:16 2005  Arnold D. Robbins  <arnold@skeeve.com>

	* Release 3.1.5: Release tar file made.

Tue Jul 26 21:44:54 2005  Arnold D. Robbins  <arnold@skeeve.com>

	Copyright dates on all relevant files updated to 2005.

Wed Jul  6 17:09:02 2005  Arnold D. Robbins  <arnold@skeeve.com>

	Minor cleanups:

	* io.c (do_index): Remove unused variables `mbclen', `mbs1' and `mbs2'.
	* node.c (wstrstr): Remove unsed variable `j'.
	(dump_wstr): `#ifdef' out, not currently needed.
	* eval.c (op_assign): Move decl of `t1' and `t2' into a separate block for
	the `! HAVE_FMOD' case. Keeps the compiler quiet. Similar for `ltemp'.

Wed Jul  6 16:51:31 2005  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (close_io): Now takes pointer to boolean parameter indicating
	if there was a problem closing standard output or standard error.
	Update it in the right places.
	* awk.h (close_io): Update the declaration.
	* main.c (main): New variable `stdio_problem'. Pass it to `close_io'.
	Check the result and exit non-zero if there was a problem.
	(usage, version): Print warning message if problems with stdout.

	Unrelated:

	* main.c (main): For call to `setlocale' for LC_MESSAGES, just use
	`#ifdef LC_MESSAGES'.  Per Bruno Haible <bruno@clisp.org>.

Wed Jul  6 16:44:58 2005  Jim Meyering  <jim@meyering.net>

	* main.c (init_fds): If any of the STDIN_FILENO, STDOUT_FILENO,
	STDERR_FILENO are initially closed, reopen them with permissions
	contrary to common usage so that any reasonable attempt to use
	them will evoke the same sort of error as reading or writing to
	a closed file descriptor would.

Mon Jul  4 09:38:29 2005  Arnold D. Robbins  <arnold@skeeve.com>

	More multibyte fixes from Kimura Koichi, <kimura.koichi@canon.co.jp>.

	* node.c (format_val, r_dupnode): Spell `wstptr' correctly.
	* regex_internal.c (build_wcs_upper_buffer): Label `offsets_needed' should not
	be inside `#ifdef _LIBC'.
	* regcomp.c (build_charclass): Fix declaration of `class_name' in prototype to
	not be unsigned.

Thu Jun 30 11:52:34 2005  Arnold D. Robbins  <arnold@skeeve.com>

	* profile.c (tree_eval): Node_not: Remember to print the exclamation
	point!  Thanks to Dan Nielsen <Dan.Nielsen@corporate.ge.com>
	for the bug report.
	* mbsupport.h: Fix spelling of HAVE_ISWUPPER. Thanks to
	Kimura Koichi, <kimura.koichi@canon.co.jp>.

Sun Jun 26 16:37:59 2005  Arnold D. Robbins  <arnold@skeeve.com>

	Unrelated changes:

	* builtin.c (do_length): Allow array argument to length().
	  Returns number of elements in array.

	* awkgram.y (yylex): Ignore carriage returns in source code. Sigh.

Wed Jun 15 22:12:15 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* node.c (isnondecimal): Check loc.decimal_point before using it.
	Avoids problems with command line assignment when locale info may
	not be set up all the way yet.

Wed Jun 15 21:59:54 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* node.c (make_str_node): If working with multibyte characters, while
	parsing string constants, keep multibyte characters together. This avoids
	problems in cases where one of the bytes is backslash. Initial patch
	supplied by Kimura Koichi, <kimura.koichi@canon.co.jp>.

Tue Jun 14 21:50:37 2005  Andrew J. Schorr     <ajschorr@users.sourceforge.net>

	Use Exponentiation By Squaring for integer powers for ^ and ^=.

	* eval.c (calc_exp, cal_exp_posint): New functions.
	(r_tree_eval): Use them.

Fri Jun  3 12:15:54 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac: Further change the hack at the end so that
	it works on Mac OS X `sed'. Sigh.

Thu Jun  2 22:44:01 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac (TYPE_SOCKLEN_T): Use `int' as default type if can't
	figure one out.
	* awkgram.y: Warn that `//' is not a C++ comment. (:-)

Thu Jun  2 20:55:27 2005  Arnold D. Robbins    <arnold@skeeve.com>

	From: Benno Schulenberg <benno@nietvergeten.nl>

	* eval.c (func_call): Take message out of gettext call since it's for debugging.
	* ext.c (get_actual_argument): Fix formatting of message.

Wed May 25 09:19:37 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac: Change hack at end that fixes Makefile to keep
	version.c to use `sed' and not `ed'. More portable to OS/2, probably
	other systems.

Mon May 23 09:01:26 2005  Arnold D. Robbins    <arnold@skeeve.com>

	Portability help from Jim Meyering.

	* io.c: Rework ifdefs for <inttypes.h> and <stdint.h>. Test them
	individually.
	* configure.ac: Add AC_C_RESTRICT and code for socklen_t from rsync.
	Check for isascii and btowc for regex.

Sat May 14 22:49:54 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* wait_any (errno): Remove decl.
	* gawk_popen: The pipe-simulated but not VMS or DOS version. Remove
	decl/use of `strdup' in favor of `emalloc' and `strcpy'.

Wed May 11 18:33:30 2005  Arnold D. Robbins    <arnold@skeeve.com>

	All files: Updated address of FSF to:

	51 Franklin Street, Fifth Floor
	Cambridge, MA  02110-1301

Wed May 11 18:19:03 2005  Jim Meyering  <jim@meyering.net>

	* configure.ac: Use AM_GNU_GETTEXT([external]).
	Reflect upgrade to gettext-0.14.4.
	Reflect renaming of `jm_'-prefixed macros.
	(AC_CONFIG_FILES): Remove intl/Makefile.

	* Makefile.am (SUBDIRS): Remove intl.
	(AM_CPPFLAGS): Remove -Iintl.

Wed May 11 11:42:06 2005  Arnold D. Robbins    <arnold@skeeve.com>

	Straighten out mess with `isblank' which is C99 <ctype.h> function.

	* configure.ac: Remove check for `isblank' in call to AC_CHECK_FUNCS.
	* regex_internal.h: #ifdef out definition of `isblank' and provide `is_blank'
	function a la dfa.c.
	* field.c: Ditto.
	* regcomp.c: #ifdef use of `isblank' and add `is_blank' use instead.

Mon May  9 08:29:37 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac: Add type check for `socklen_t', fixes compile
	warning on AMD/64 Linux.
	* io.c (socketopen): Change type of socket lenght variables
	to `socklen_t' from `size_t'.

Thu May  5 22:00:03 2005  John E. Haque <j.eh@mchsi.com>

	* io.c (iop_alloc): Let a input processor hook installed via
	`register_open_hooks' open its own fd in case gawk does not know
	how to open it.
	(iop_open): Call `os_close_on_exec' after `iop_alloc'.
	ADR: If `iop_alloc' returns NULL but the fd is valid, close
	the fd to avoid an fd leak.

Mon May  2 08:05:59 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* eval.c (update_ERRNO): Don't use `return' in a `void' function.
	* awk.h (AWKNUM): Back out use of `long double' based on LDBL_MANT_DIG.
	* builtin.c (tmp_integer): Back out extra ifdefs.

Fri Apr 29 13:01:05 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac: Look for `isblank' function.
	* field.c: Add define for `isblank' if we don't have it.

Fri Apr 29 12:01:33 2005  Julian Foad  <julianfoad@btopenworld.com>

	From grep.  Doesn't seem to affect awk.

	* dfa.c (lex): Fix bug #9519: "echo do^re | grep do^re" was
	failing to find a match. [Towards end, set `lasttok' before
	returning `c'.]

Fri Apr 29 00:28:46 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac: Jump through an amazingly convoluted hoop to get
	config.status to keep version.c upon `make distclean'. Seems to
	work though.

Thu Apr 28 23:40:02 2005  Stepan Kasal  <kasal@ucw.cz>

	* configure.ac (PRINTF_HAS_F_FORMAT): Some cosmetic changes.
	(custom.h): Don't cat custom.h at the end of config.h; instead, use
	  AH_BOTTOM([#include "custom.h"])
	* awklib/Makefile.am (AM_CPPFLAGS): Add $(top_srcdir) so that
	  custom.h can be found.

Thu Apr 28 23:21:22 2005  Jim Meyering  <jim@meyering.net>

	* field.c (set_FIELDWIDTHS): Tighten up the code to accept FIELDWIDTHS
	values in [1..INT_MAX], e.g., detect overflow and invalid strings,
	and reject strings starting with `-'.

Thu Apr 28 23:05:33 2005  Stepan Kasal  <kasal@ucw.cz>

	* dfa.c (parse_bracket_exp_mb): Shorten one part of the code, to get
	  closer to grep's copy.

Thu Apr 28 23:00:58 2005  Pat Rankin    <rankin@pactechdata.com>

	* builtin.c (format_tree) [#if VAXCRTL]:  For floating point
	  formatting, reject zero_flag if using old VAXCRTL run-time
	  library to avoid getting erroneous results which appear as if
	  numerically incorrect (due to an embedded space in some cases,
	  extra trailing zeroes in others) rather than just misformatted.
	  `hsprint' test still fails, but not as badly.

Thu Apr 28 19:12:03 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* re.c (reflags2str): Add three new RE_ flags from current regex.h
	to bring the table up to date.

	* builtin.c (format_tree): Save 2 spare bytes instead of one. Suggested
	by Stepan Kasal.

Thu Apr 28 18:16:09 2005  Andrew J. Schorr     <ajschorr@users.sourceforge.net>

	* awk.h (IOBUF): Add new fields `opaque', `get_record', and `close_func',
	to support insertion of an alternate input processor.  This is used
	by the XML extension.
	(register_deferred_variable, register_open_hook, update_ERRNO_saved):
	Declare new functions.
	(load_environ, load_procinfo): Remove declarations -- these functions
	are no longer global, since we use register_deferred_variable instead.
	* awkgram.y (register_deferred_variable): New function to allow
	calling code to register special variable names that trigger a callback
	upon the first reference.  This is now used to implement ENVIRON
	and PROCINFO.
	(variable): Search the list of deferred variables instead of hardcoded
	tests for ENVIRON and PROCINFO.
	* eval.c (set_BINMODE): Fix spelling of "arbitrary" in warning message.
	(update_ERRNO_saved): New function that allows the caller to specify
	the errno value instead of using the current value.
	(update_ERRNO): Implement by calling update_ERRNO_saved(errno).
	* io.c (iop_close): Call `iop->close_func' if non-NULL.
	(close_redir): Should save `errno' value, otherwise `lintwarn' messages
	might update it.  Then use `update_ERRNO_saved' to set ERRNO.
	(do_getline): Call `update_ERRNO_saved' to set ERRNO based on the
	error code returned by the redirect function (instead of the current
	value of errno).  Similarly, use `update_ERRNO_saved' to set ERRNO
	based on the value returned by `get_a_record'.  But add a special
	check to avoid updating ERRNO if `get_a_record' returns an error
	code value of -1 (this is used by the XML extension which already
	sets ERRNO before returning).
	(register_open_hook): New function to register a function to be
	called whenever a new data file is opened.  This can be used to
	install a special input processor (as in the XML extension).
	(iop_alloc): Call registered open hook.
	(get_a_record): If a `get_record' method has been set, call that instead.
	* main.c (init_vars): Use `register_deferred_variable' to implement
	ENVIRON and PROCINFO.
	(load_environ, load_procinfo): Now static instead of global.
	* doc/gawk.texi: Document new internal functions `update_ERRNO_saved',
	`register_deferred_variable', and `register_open_hook'.

Thu Apr 28 10:50:10 2005  Arnold D. Robbins    <arnold@skeeve.com>

	* array.c (assoc_find, do_delete): Change incorrect uses of STREQN
	to memcmp.
	* builtin.c (do_index): Same.
	* field.c (set_FS): Same.
	* io.c (redirect, getredirect, do_close, set_RS): Same.
	* re.c (reisstring): Same.

Wed Apr 27 21:35:57 2005  Arnold D. Robbins    <arnold@skeeve.com>

	Allow for long double. Initial changes from  Jean-Marc Saffroy
	<jean-marc.saffroy@ext.bull.net>.

	* awk.h (AWKNUM): If have long doubles (LDBL_MANT_DIG), define AWKNUM
	as long double, otherwise just use double.
	* builtin.c (format_tree): Change type of tmpval to double.
	(do_strtonum): Same for `d' and types used in casts.
	(tmp_integer): Don't do bit shifting if have long doubles.

	Unrelated, from Andrew J. Schorr:

	* io.c (close_one): Check for RED_FILE|RED_WRITE, not just RED_FILE.

Mon Apr 25 12:23:18 2005   Andrew J. Schorr	<aschorr@telemetry-investments.com>

	* eval.c (r_tree_eval): In Node_assign_concat case, when copying string
	constants, include the terminating zero byte.

Fri Apr  1 06:26:31 2005   Arnold D. Robbins    <arnold@skeeve.com>

	Update to Automake 1.9.5.

	* INSTALL, aclocal.m4, depcomp, install-sh, missing,

	* random.h: Remove include of config.h and move it to ...
	* random.c: Here.  Move include of random.h back to where it was.

	* regcomp.c, regex.c, regexec.c: NUKED all use of alloca not inside

	Fix count of bytes to copy in call to `memcpy'.
	Thanks to Kimura Koichi, <kimura.koichi@canon.co.jp>.

Tue Feb  8 19:26:22 2005   Pat Rankin  <rankin@pactechdata.com>

	* regcomp.c (init_dfa): Avoid strcasecmp() since regex.c doesn't
	use awk.h and none of the assorted other included header files
	are guaranteed to declare it.
	(parse_expression): Modify casts for the string arguments passed to
	build_charclass_op() to fix char * vs unsigned char * mismatch.
	(parse_bracket_exp): Likewise add cast for the string argument

	* main.c (main):  Call `close_io', without its result affecting
	the exit status.  Super small, super dark corner.

	See test/exitval2.awk.

Tue Feb  1 11:58:29 2005   Arnold D. Robbins    <arnold@skeeve.com>

	* regex.h (__APPLE_CC__): Removed test and definition of __restrict.

Sat Jan 22 22:30:40 2005   Arnold D. Robbins    <arnold@skeeve.com>

	Reinstate patch of 18 Nov 2001, for VMS, at least:

	* random.c (srandomdev): ifdef-out.  Lots of compile time
	  problems on multiple platforms, and gawk doesn't even
	  use the routine.  The heck with fine-grained solutions.

Thu Jan 20 14:15:32 2005   Arnold D. Robbins    <arnold@skeeve.com>

	* awkgram.y (LEX_FOR): Free NAME tokens in transformation of
	`for (iggy in foo) delete foo[iggy]' into `delete foo'.
	Thanks and a tip of the hatlo to Valgrind.

	Per Bruno Haible.

Wed Jan 19 18:29:23 2005   Arnold D. Robbins    <arnold@skeeve.com>

	* awkgram.y (yylex): Improve parsing of numeric constants
	and hex values, via a push from Paul Eggert. See test/hex.awk.

	* regex_internal.c (re_node_set_alloc): If `size' is 0, just
	zero out the structure. From valgrind.

Tue Jan 18 17:23:25 2005   Arnold D. Robbins    <arnold@skeeve.com>

	Make gawk multibyte aware.  This means that index(), length(),
	substr() and match() all work in terms of characters, not bytes.

	Add code to deal with wide strings.
	(str2wstr, dump_wstr, wstrstr, wcasestrstr): New functions.

Sun Jan 16 15:10:35 2005   Arnold D. Robbins    <arnold@skeeve.com>

	* random.h (int32_t): Define this type.

Thu Jan 13 14:38:13 2005   Arnold D. Robbins    <arnold@skeeve.com>

	Cause `configure --disable-nls' to still allow locale-correct
	formating of numeric values.

	* builtin.c (format_tree): Change #ifdefs to only test HAVE_LOCALE_H.
	Improve code for ' flag so that extraneous separator is not included if
	number of digits is multiple of locale separater count (3, 6, 9, etc.)
	* dfa.c (dfaparse): Change ifdef to only test #ifdef LC_COLLATE.
	* eval.c (fmt_ok): Remove ENABLE_NLS from #ifdef test.
	* gettext.h: Include <locale.h> on both sides of test. Should really
	be factored out.
	* main.c (loc): Remove ENABLE_NLS from #ifdef test.
	(main): Same in call to localeconv().

	Update to Automake 1.9.3.

	* INSTALL, alocal.m4, config.guess, config.sub, depcomp,
	install-sh, missing, ylwrap: Updated.

Mon Jan  3 11:23:36 2005   Arnold D. Robbins    <arnold@skeeve.com>

	Fix obscure issue. ^ in RS should only match at the very
	beginning of the input.  Essentially, the file is one long
	string.  To do this, use the `not_bol' flag in the `struct
	pattern_buffer'.  Thanks to Stepan Kasal for pointing out the
	problem and to Andreas Schwab for pointing out the mechanism
	for a solution.

	* awk.h (RE_NEED_START, RE_NO_BOL): New flags for `research'.
	(IOP_AT_START): New flag for IOBUF.
	(research): Last parameter is now `flags'.
	* builtin.c (do_match, sub_common): Change calls to `research'.
	* eval.c (interpret, match_op): Same.
	* field.c (re_parse_field): Same.
	* io.c (spec_setup): Add IOP_AT_START flag.
	(iop_alloc): Same.

	add RE_NO_BOL to flags value in call to `research'.
	(get_a_record): Clear IOP_AT_START upon return from `*matchrec'.
	(iopflags2str): Add IOP_AT_START to table.  Also IOP_CLOSED,
	which was missing. (Ooops.)
	* re.c (research): Last paramater is now flags.  Modify logic to
	handle RE_NO_BOL case by setting the right bit initially. Clean
	up control flow so that it's cleared before returning.  If RE_NO_BOL,
	don't bother with the dfa matcher, as it doesn't have an analogous
	capability.

Wed Dec 22 12:33:48 2004   Arnold D. Robbins    <arnold@skeeve.com>

	For --exec, don't allow x=y assignments where filenames would be.
	Do allow -v.  This is because we assume --exec is used mainly for
	CGI stuff and we don't want var assigns to affect the code.

	Suggested by Stepan Kasal; motivated by reading about web security.

	* main.c (disallow_var_assigns): New variable.
	(main): Set the var for --exec.
	(arg_assign): Check it appropriately.

Sun Dec 19 17:27:09 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* builtin.c (do_gensub): Make `global' flag smarter, such that
	a string numeric constant (e.g., "3") acts like a numeric
	constant.
	* node.c (r_force_number): Not really related: Only set NUMCUR
	if we actually convert some digits.

Sun Dec 19 16:08:50 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* dfa.h, dfa.c: Synchronize with what's happening in GNU grep
	development.  Effectively only minor whitespace changes and some
	slight code motion of ifdefs and includes.
	* hard-locale.h: New file, extracted from old dfa.c.
	* Makefile.am (base_sources): Add hard-locale.h.

Sun Dec 19 11:13:45 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* io.c (socketopen): Change type of `readle' and `namelen'
	variables to size_t.  For QNX, but a good idea anyway. Thanks
	to `Anthony' (rz1a@mail.ru).

Mon Dec  6 11:11:22 2004   Arnold D. Robbins    <arnold@skeeve.com>

	Undid change of Mar 9 2004, to add gofast patch.  It gets things
	wrong for gawk.  This removes the bandaid of ifdef-ing out the
	main check.  Eventually this'll all get straightened out in the
	GNU grep code.

	* dfa.c (buf_offset): Removed.
	(SKIP_REMAINS_MB_IF_INITIAL_STATE): Removed use of buf_offset, do
	free `mblen_buf', `inputwcs'.
	(match_anychar, match_mb_charset, transit_state_consume_1char,
	transit_state): Remove use of buf_offset in mblen_buf.
	(dfaexec): Use `free' and `malloc', not `realloc'.

Mon Dec  6 10:55:37 2004   Fumitoshi UKAI       <ukai@debian.or.jp>

	Forwarded from james@nocrew.org, the Debian contact.

	* dfa.c (parse_bracket_exp_mb): 
	1. Build range correctly when IGNORECASE for [a-a] to also get 'A'.
	2. For [:lower:] and [:upper:], if ignoring case, set type string
	   to "alpha".  This parallels code in the regex routines.
	3. Reset wc1 to EOF when parsing bracket expressions.

Mon Nov 29 18:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* io.c (redirect): When allocating a new struct redirect, set
	rp->pid to -1, not 0, so that code checking for EOF on an
	input pipe works correctly.

Thu Nov 25 14:22:41 2004  Stepan Kasal  <kasal@ucw.cz>

	* Makefile.am (MAINTAINERCLEANFILES): Add.

	regexes, /.../i and /.../s.  Not that it'll help anyone.

Wed Oct 27 14:25:18 2004  Stepan Kasal  <kasal@ucw.cz>

	* builtin.c (do_tolower, do_toupper): Fix the wide char handling,
	  especially when the lowercased char doesn't ocuppy the same
	  number of bytes as its uppercase equivalent.  Make use of ...
	(wide_tolower_toupper): ... this new static function.

Mon Oct 25 11:51:14 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* builtin.c (bchunk, bchunk_one, cksize): Change type of `olen'
	to size_t from long.  It is the 21st century now, after all...
	Thanks to Stepan Kasal.

Mon Oct 11 10:49:09 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* awkgram.y (yylex): Improve lint warnings for non-decimal constants.
	* node.c (isnondecimal): Made a little smarter, thanks to Stepan Kasal.

Thu Oct  7 21:59:38 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* dfa.c (dfamust): Redo fix of 22 Sep to match code from
	current GNU grep.

Sun Oct  3 23:06:00 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* node.c (isnondecimal): Made smarter, so that 0xEE does
	register as non-decimal. Added parameter to indicate use of
	locale's decimal point and changed declaration and callers.

Tue Sep 28 18:38:17 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* node.c (isnondecimal): New function, now smarter.

Wed Sep 22 11:24:46 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* dfa.c (dfamust): At end, check results of `malloc'.
	Based on bug report from Sorav Bansal <sbansal@stanford.edu>
	for grep.

Mon Sep 20 13:18:18 2004   Arnold D. Robbins    <arnold@skeeve.com>

	New --exec option.  Needed for gawk CGI scripts to prevent
	arbitrary options and/or source getting passed in from the web.

	* main.c (optab): New long option, --exec.
	(main): Catch it.  Like -f but end option processing.
	(usage): Add it to the usage message.

	Thanks to John DuBois and Don Stokes for their input.

	Unrelated:

	* dfa.c (dfaexec): Disabled caching into buffer that bypasses
	multibyte initialization, since it can get things wrong. Thanks
	to Andreas Schwab <schwab@suse.de>.

Mon Sep 20 12:59:42 2004   Andreas Schwab  <schwab@suse.de>

	* awkgram.y (nextc): Check for end of lexer buffer before
	advancing ring buffer index.

Wed Sep  8 09:54:53 2004   Arnold D. Robbins    <arnold@skeeve.com>

	the program, since a variable assignment with -v can leave the 
	locale set incorrectly.

	Thanks to Sirix <sirix@poczta.onet.pl> for reporting the problem.

Wed Aug 25 18:55:30 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* main.c (UPDATE_YEAR): New constant at top of file, where we
	won't miss it.
	(copyleft): Use it.

Sun Aug 22 17:26:39 2004   Stepan Kasal  <kasal@ucw.cz>

	Define gawk_mb_cur_max even if there is no mbs support, as
	``const int'' and assign 1 to it.
	This fixes a bug in re.c where #ifdef MBS_SUPPORT was missing.

	* awk.h (gawk_mb_cur_max): Declare.
	* main.c (gawk_mb_cur_max): Define.
	* awkgram.y (nextc_is_1stbyte): Without mbs support, define to 1.
	* builtin.c (index_multibyte_buffer): Define a dummy function
	  when there is no mbs support.
	* awkgram.y, builtin.c, re.c: Remove some `#ifdef MBS_SUPPORT'.

Sun Aug 15 22:08:04 2004   Arnold D. Robbins    <arnold@skeeve.com>

	Import current FreeBSD random.c.  Make it work for gawk.
	Needed for cases where long is more than 32 bits.

	* random.c: Imported from FreeBSD. Header includes tweaked.
	* random.h: Typdef gawk_uint32_t appropriately and #define uint32_t
	  to it.
	* configure.ac: Add calls to AC_CHECK_SIZEOF for unsigned int
	and unsigned long.

	Started with
	http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/stdlib/random.c
	Thanks to Andreas Schwab <schwab@suse.de> for the pointer.

Thu Aug 12 13:09:53 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* main.c (copyleft): Fix copyright year.

Mon Aug  2 12:18:15 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* Release 3.1.4: Release tar file made.

Mon Aug  2 12:17:40 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac: Fix the hack. Do the sed on `Makefile',
	not `Makefile.in'.  Sigh.

Sun Aug  1 14:48:30 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* configure.ac: MAJOR HACK: At end, remove version.c from Makefile.in
	variable `CONFIG_CLEAN_FILES' so that `make distclean' doesn't
	remove version.c.

Mon Jul 19 17:07:27 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* config.guess, config.sub: Updated from Savannah CVS.

Fri Jul 16 10:59:07 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* re.c (make_regexp): Bracket code using `gawk_mb_cur_max'
	inside `#ifdef MBS_SUPPORT'.

Thu Jul 15 12:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>

	* dfa.c (parse_bracket_exp_mb):  If doing case folding,
	include the other case for regular characters inside [...].

	* re.c (make_regexp): Smarten up handling of IGNORECASE,
	particularly for multibyte character sets. Sigh.

Wed Jul 14 16:25:23 2004  John Haque  <mary1john8@earthlink.net>

	* eval.c (interpret): For `Node_K_return', use `copynode'
	and not `dupnode' for non-PERM, non-TEMP values.
	(func_call): Don't add TEMP flag to returned value.

	These two fix a problem uncovered by the July 8 change in
	`assoc_lookup'.

Wed Jul 14 16:14:09 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (node_common): Add check `lexeme >= lexptr_begin',
	from valgrind run.

	* awkgram.y (output_redir): Make sure not to dereference NULL
          pointer.  The bug was triggered by the following code:

                gawk 'BEGIN{print "date" |& getline}'

        No test case created, beacuse of the following:
        Correct interpretation involves executing "1" or "0" -- as the user
        may have defined this, we would have to override this in the test
        script.  It's not worth the hassle.

Thu Jul  8 12:59:49 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h (load_casetable): Name changed from `load_ignorecase'.
	* eval.c (load_casetable): Name changed from `load_ignorecase'.
	Fix all uses.

Thu Jul  8 12:32:13 2004  John Haque  <mary1john8@earthlink.net>

	* awkgram.y (get_src_buf): Fix off-by-one error to avoid "does not end
	in newline" messages.
	* array.c (assoc_lookup): Small performance hack: for TEMP subs nodes,
	use its string memory for ahname.
	* ext.c (get_actual_argument): Minor code cleanup.
	* builtin.c (do_lshift, do_rshift, do_and, do_or, do_xor, do_compl):
	fixed to issue "non-numeric argument" lint warnings before using
	`force_number'.

Mon Jun 21 16:53:35 2004  Arnold D. Robbins  <arnold@skeeve.com>

	More changes from John Haque to rationalize extension functions.

	* awk.h (get_curfunc_arg_count): Name changed from

	args passed at call time.
	* ext.c (get_argument): Update range check.
	(get_actual_argument): Simplify the code.

	new function declarations.
	(get_scalar_argument, get_array_argument): new macros.
	* awkgram.y (check_special): new function.
	(yylex): Use `check_special' to search `tokentab'.
	(dump_funcs): Always count functions, in order to get dynamic ones.
	Removed bogus use of `static' on `tab' variable.
	* eval.c (struct fcall): Change type of `count' to `size_t'.
	(get_curfunc_parm_count): New function.
	(push_args): Set `r->rnode' to NULL for local variable.
	* ext.c (make_builtin): Add sanity checking for presence and
	name of new function, and that it's not a redefinition.
	(get_argument): Check that requested arg is within range of actual
	number of parameters.  Also clean up logic for Node_var_new,
	Node_var_array, Node_array_ref.
	(get_actual_argument): New function.
	* profile.c (pp_builtin): Better handling of dynamic extension function.

Sun Jun 13 14:32:22 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (redirect): Conditionalize checking for process recovery
	on `#ifdef PIPES_SIMULATED'.  Needed for MS-DOS and VMS.
	* builtin.c (tmp_integer): Change bracketing of magic test to
	`#ifdef HAVE_UINTMAX_T' which is more general and more correct.

Wed Jun  9 21:36:01 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (casetable): Remove `const'.
	(load_ignorecase): New function.  Loads locale-correct values in
	upper 128 bytes.
	(set_IGNORECASE): Call `load_ignorecase'.

Tue Jun  8 14:04:19 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (get_src_buf): Make sure that value from
	`optimal_bufsize' is reasonable.  Increase it if not.

Tue Jun  8 13:54:28 2004  John E. Haque      <mary1john8@earthlink.net>

	* awkgram.y (statement:LEX_FOR): Fix bug in loop to `delete a'
	optimization.
	* io.c (format_tree): Check for out of range values for
	positional specifiers.

Mon Jun  7 17:02:48 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (tmp_integer): Bracket the magic test inside
	`#ifndef VMS'.

	* awk.h (child_catcher): Remove declaration.
	* main.c (main): Remove `signal' calls for SIGCLD, SIGCHLD.
	* io.c (child_died, child_signo, child_catcher): Removed.
	(get_a_record): Remove code checking for death of child.
	(redirect): If `rp' matches and is at EOF and type is input
	pipe, and `rp->pid' is not -1, call `wait_any' to reap the
	child.  This is a heuristic, but it works pretty well.

Sun Jun  6 18:35:17 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (get_a_record): Restore use of `memmove' instead of
	memcpy. Otherwise some tests break on some systems. We think.
	(child_died): Don't reset signal handler; breaks on some S5 systems.
	(get_a_record): Reset handler if child_died. Still flaky on Solaris.
	* configure.ac (version.c): Made from version.in again, for
	non-Unix systems.
	* Makefile.am (base_sources): Add version.c back.
	* version.in: Include config.h for definition of const.
	* main.c (version_string): Add back declaration, don't
	include "version.i".
	(main): Don't install child_catcher on Sun. (HACK)

Thu Jun  3 14:06:06 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c (version_string): Removed declaration, since
	version.i is included directly.
	* version.in: Removed test for definition of const.

Tue Jun  1 19:23:53 2004  Stepan Kasal  <kasal@ucw.cz>

	* Makefile.am (base_sources): Don't mention version.c, so that
	it doesn't get distributed.
	* po/POTFILES.in: remove version.c
	* configure.ac: Create version.i from version.in.
	* main.c: include version.i.

Tue Jun  1 18:33:32 2004  Arnold D. Robbins  <arnold@skeeve.com>

	on Thu, 30 Oct 2003 13:11:42 -0500.

	* regex_internal.h (re_realloc): Allow for SunOS pre-Standard C
	`realloc' which doesn't accept NULL pointers.
	* awk.h (erealloc): Same.

	Unrelated. Change suggested by Peter Sobisch <petersob@gmx.net>, have
	PROCINFO["version"] be the version of gawk:

	* main.c (load_procinfo): Add in version.

	Unrelated: Avoid warning:

	* main.c (main): Cast calls to `bindtextdomain' and `textdomain' to
	void.  Avoids diagnostic with `configure --disable-nls'.
	* dfa.c (check_matching_with_multibyte_ops): Remove unneeded nested
	#ifdef, per Scott Deifik (scottd@amgen.com).  Also fix some spelling
	errors in comments.

Tue Jun  1 18:26:45 2004  Paul Eggert  <eggert@twinsun.com>

	Fix a bug reported by Mike Romaniw <msr@micromonumental.com>
	to bug-gnu-utils on 2003-09-27: compl(compl(0xf0f)) returned 0xfff
	on hosts with 64-bit uintmax_t and 64-bit IEEE-764 double, due to
	rounding errors.

	* doc/gawk.texi (Bitwise Functions): Leading nonzero bits are
	removed in order to fit the result into a C 'double' without rounding
	error.
	* builtin.c: Include <float.h> if available.
	(FLT_RADIX, FLT_MANT_DIG, DBL_MANT_DIG): Define if not already defined.
	(AWKSMALL_MANT_DIG, AWKNUM_MANT_DIG, AWKNUM_FRACTION_BITS): New macros.
	(tmp_integer): New function.
	(do_lshift, do_rshift, do_and, do_or, do_xor, do_compl): Use them.

	local variables.

Mon May 31 11:49:20 2004  Stepan Kasal  <kasal@ucw.cz>

	* replace.c: #undef DEBUG before including mktime.c, it has
	  different meaning there.

Mon May 31 08:25:30 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (get_actual): Add extra error message for `delete f'
	inside body of function `f'.

Mon May  3 09:53:34 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* Makefile.in, */Makefile.in: Updated to automake 1.8.4.
	* config.guess, config.sub: Same.
	* aclocal.m4, depcomp, install-sh: Same.

Mon May  3 09:24:45 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* configure.ac: Look for missing `strtoul'.
	* replace.c: Include missing_d/stroul.c if not HAVE_STRTOUL.
	* io.c (devopen): Use `strtoul' instead of `strtod' for
	  extracting fd number from "/dev/fd/N".  (Thanks to Jim Meyering.)
	* field.c (set_FIELDWIDTHS): Use `strtoul' instead of `strtod'
	  when parsing FIELDWIDTHS values.  (Thanks to Jim Meyering.)

Mon Apr 19 20:12:57 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* Makefile.in, */Makefile.in: Updated to automake 1.8.3.
	* config.guess, config.sub: Same.

2004-03-18  Stepan Kasal  <kasal@ucw.cz>

	* eval.c (make_scalar): Comment clarification.

	* array.c (get_actual): Remove the condition ``canfatal''
	  before ``cant_happen()''; if the data are consistent, we
	  simply cannot get there with a non-func Node_param_list,
	  no matter whether we are called via get_array or not.

	* awkgram.y (variable): Make one longer message, to help translators.

Tue Mar  9 17:34:10 2004  Arnold D. Robbins  <arnold@skeeve.com>

	Adapted `gofast' patch from Redhat Enterprise version of grep
	to current dfa.c.

	* dfa.c (buf_offset): New variable.

	transit_state): Use buf_offset in mblen_buf.
	(dfaexec): Realloc things instead of free and malloc.

	(AC_CHECK_FUNCS): Removed `mbrtwoc'.
	(REGEX_MALLOC): Removed. Not needed for new regex* routines.

	* re.c (research): Removed comment and check for return of -2
	since that was for old regex using alloca or REGEX_MALLOC.

Wed Mar  3 17:10:16 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (close_one): Don't close stdout or stderr; can happen if
	/dev/stdout or /dev/stderr are used in redirection and all the
	open files get used.

Sun Feb 29 12:17:37 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* regcomp.c (build_charclass, build_charclass_op): Change type of

	* awkgram.y (get_src_buf): Rewritten to better manage input and
	supplying newlines on command line programs.  Fixes problems reading

	Unrelated fixes from mary1john8@earthlink.net:

	* node.c (format_val): For no malloc case, free s->stptr if necessary.
	* io.c (nextfile): Add missing call to `unref(FILENAME_node->var_value)'
	for no files case.
	(close_redir): Remove file from redirection list even if fp is
	stdout or stderr.

Tue Feb 24 12:11:34 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* regex_internal.c (build_wcs_upper_buffer): Enclose `offsets_needed'
	label in `#ifdef _LIBC' to silence `unused label' compiler warning.

Tue Feb 24 11:57:18 2004  Nelson H.F. Beebe  <beebe@math.utah.edu>

	* regcomp.c (parse_expression): Add cast to (unsigned char *) in calls
	to `build_charclass_op'.
	* regex_internal.c (build_wcs_buffer): Add cast to char* in call to
	`wcrtomb'.
	* regex_internal.h (bitset_not, bitset_merge, bitset_not_merge,
	bitset_mask, re_string_char_size_a, re_string_wchar_at,
	re_string_elem_size_at): Change to use prototypes.
	(re_string_char_size_at, re_string_wchar_at, re_string_elem_size_at):
	Declare as `internal_function'.

	* Makefile.am: Add rule to make .i files.  This assists in debugging.
	* awk.h (m_tree_eval): Add casts to NULL.  (Some compilers are just
	dumb. ADR)

Mon Feb 23 15:58:39 2004  Arnold D. Robbins  <arnold@skeeve.com>

	Clean up occupied process slots of children that have died:

	* awk.h (child_catcher): New function, declare it.
	* main.c (main): Catch SIGCHLD/SIGCLD with `child_catcher'.
	* io.c (child_died): New static variable.
	(child_catcher): New function, sets `child_died', reinstalls self
	as signal handler.
	(close_rp): New function: isolates actual fp/iop closing logic.
	(close_redir): Call `close_rp'.
	(get_a_record): Check `child_died' and call `wait_any(0)' if so.
	Add descriptive comment.

	Unrelated clean up:

	* eval.c (fcalls): Renamed from `fcall_list'. All uses changed.
	(pop_fcall, push_args, dump_fcall_stack): Adjusted to use indexing
	on `fcalls' instead of a pointer into it. Avoids hassles if `fcalls'
	is realloc-ed during recursive tree_evals. Thanks to BWK.

	* config.guess, config.sub: Updated from Savannah.

2004-02-19  gettextize  <bug-gnu-gettext@gnu.org>

	* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.14.1.

Wed Feb 18 12:40:09 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (rule): Use `msg' not `warning' for `must have an
	an action part' message.  `warning' is wrong, since it's a real error.

Mon Feb 16 12:17:39 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c, eval.c, builtin.c: Change test for `#ifdef HAVE_LOCALE_H'
	to `#if ENABLE_NLS && defined(HAVE_LOCALE_H)' so that builds with
	`configure --disable-nls' will actually work on non-glibc systems.

Thu Feb 12 02:05:34 2004  Stepan Kasal  <kasal@ucw.cz>

	Lots of misc changes from Stepan Kasal integrated.

	* array.c: Various variables and parameters of static functions
	changed from int to long, in order to prevent overflow.

	* eval.c (make_scalar): New function; takes care of everything
	that has to be done when a node of type Node_var_new or
	Node_array_ref changes to a scalar variable.
	(tree_eval, get_lhs): Call it.
	(tree_eval): From now on, tree_eval(NULL) doesn't work;
	it reports an internal error.
	* awk.h (m_tree_eval): Likewise for the two macro versions.
	* awkgram.y (statement): Make sure the Node_K_return's lnode is
	always the return value, never NULL.

	* Makefile.am (install-exec-hook, uninstall-links): Make use of
	$(VERSION).
	(INCLUDES): Renamed to AM_CPPFLAGS.
	(AM_CPPFLAGS): The file libintl.h is generated in the
	build subdirectory intl, not in the directory $(srcdir)/intl.
	(diffout): New target is an alias for ``make -C test diffout.''

	* README_d/README.hpux: Change the whitespace in the appended patch,
	so that it applies to the current source.
	* posix/gawkmisc.c: Change a tab to a space (needed for the above).

        Make version control more in the style of current autotools:

	* configure.ac: Remove obsolete versions of macros:
	AM_INIT_AUTOMAKE doesn't need any parameters.
	AC_OUTPUT shouldn't have any parameters either.
	Its parameters go to a new macro: AC_CONFIG_FILES.
	AC_CONFIG_HEADERS moved near the end of the file.
	* configure.ac: Add [version.c:version.in] to AC_CONFIG_FILES
	* version.in: Modify for autoconf substitutions.

	Roman.Putanowicz@iecn.u-nancy.fr for pointing out the problem.

Fri Feb  6 12:09:55 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* configure.ac: Check for `wctype', `wcscoll' and `iswctype'.

	* Makefile.am (CLEANFILES): Added.

Thu Feb  5 18:05:12 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* configure.ac (HAVE_WCTYPE_T): New test code added.
	* dfa.h (wctype_t): Define if system doesn't. Needed here too
	for other files that include dfa.h.
	* dfa.c (wctype_t): Define if system doesn't.
	(lex): Manually fill in arrays used for char class range testing
	so will work on c89 and older compilers.

	* main.c (main): When checking for `close_io' failure, only set
	`exit_val' to 1 if not already exiting.

	* regcomp.c (regerror): Remove use of mempcpy.  Generates too
	many compiler warnings.
	* configure.ac (AC_CHECK_FUNCS): Don't bother checking for it.

Wed Feb  4 17:34:47 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* getopt.h (__THROW): Only define it if C++. The __GNU_PREREQ
	macro is a major headache.

2004-02-02  Paolo Bonzini  <bonzini@gnu.org>

	* regexec.c (check_matching): Add P_MATCH_FIRST parameter.
	(re_search_internal): Pass new parameter to check_matching.
	(check_matching): Unless a parenthesized group is found at the
	beginning of the regexp, advance P_MATCH_FIRST until we entered
	a state different from the initial state.

Mon Feb  2 15:52:37 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* re.c (research): Change last param to re_search to pass
	NULL if `need_start' is false.  May give us a marginal speed gain.

Thu Jan 29 17:04:51 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (sub_common): Fix logic for `&' in replacement for
	multibyte case.  Simplify code a bit.

Tue Jan 20 10:41:45 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* configure.ac: Add check for `memmove'.
	* replace.c: Include missing_d/memmove.c if don't have `memmove'.

Sun Jan 18 12:01:29 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (sub_common): Add comment and support for 2001 POSIX

	* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.13.1.
	* intl/*: Updated to 0.13.1.

Fri Jan 16 08:16:38 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* getopt.h, getopt.c, getopt1.c: Synced to GLIBC version:
	getopt.c:	1.51
	getopt.h:	1.18
	getopt1.c:	1.9

Thu Jan 15 15:28:48 2004  Arnold D. Robbins  <arnold@skeeve.com>

	Here we go again:

	* regcomp.c, regex.h, regex.c, regex_internal.h, regex_internal.c,
	regexec.c: Sync to GLIBC version, but with bug fixes.  GLIBC
	CVS versions:

	regcomp.c: 1.76
	regexec.c: 1.55
	regex.c: 1.125
	regex.h: 1.30
	regex_internal.c: 1.39
	regex_internal.h: 1.45
	regexec.c: 1.55

	* acinclude.m4: Removed, not needed for automake 1.8.x.
	* configure.ac: Updated to autoconf 2.59.

	Everything else updated to automake 1.8x and autoconf 2.59.

Wed Jan 14 14:26:36 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* dfa.c, dfa.h: Updated manually with most of the changes in
	grep 2.5.1.  That version lost the ability to match newlines
	in the data, so the merge had to be done by hand.  Sigh.

2004-01-12  Paolo Bonzini  <bonzini@gnu.org>

	ALLOCA patch from
	http://sources.redhat.com/ml/libc-alpha/2004-01/msg00099.html
	added.

	* regcomp.c [_LIBC && !RE_ENABLE_I18N]:
	Drop code to support this, it is never true.
	(build_range_exp) [!_LIBC]: Do not create a range
	in MBCSET for a single-byte character set.
	(build_range_exp) [_LIBC]: Do not create a range
	in MBCSET for a single-byte character set without
	collation elements.
	(init_dfa): Do not conditionalize on _LIBC, it
	just makes the code less clear.
	(parse_bracket_exp): Use NON_MATCH variable in
	addition to "mbcset->non_match", not as an
	alternative.
	(build_charclass_op): rename NOT parameter to
	NON_MATCH, use it instead of declaring a variable. 
	(parse_bracket_exp) [!_LIBC]: Pass NULL for MBCSET
	if the character set is single-byte.

Wed Jan  7 15:23:04 2004  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (mk_rexp): Set n->re_cnt to 1. Makes reinstated
	dfa code actually take effect!  Don't know how I missed this.

	Unrelated: sync regex code to glibc.

	* regcomp.c, regex.h, regex.c, regex_internal.h, regex_internal.c,
	regexec.c: Sync to GLIBC version, but with bug fixes.  GLIBC
	CVS versions:

	regcomp.c: 1.74
	regex.c: 1.124
	regex.h: 1.30
	regex_internal.c: 1.39
	regex_internal.h: 1.43
	regexec.c: 1.55

	* regcomp.c (peek_token): Temporarily, we hope, disable \s and \S
	operators.  Too much trouble to document right now.
	* dfa.c (lex): Add code for \s and \S but disable it until
	next release.

Wed Dec 24 15:28:57 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (r_tree_eval): For Node_assign_concat, add
	call `free_temp(r)'. Thanks to mary1john8@earthlink.net.

Mon Dec  1 10:25:52 2003  Arnold D. Robbins  <arnold@skeeve.com>

	CONSTVAL not needed if we test PERM instead. Thanks to
	mary1john8@earthlink.net. See test/concat3.awk.

	* awk.h [CONSTVAL]: Removed.
	* eval.c (flag2str): Removed CONSTVAL from table.
	(r_tree_eval): For Node_assign_concat, it's enough to check
	if l->flags has PERM clear.
	* awkgram.y (yylex): Removed use of CONSTVAL for YSTRING and YNUMBER.

Mon Nov  3 16:33:26 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (get_src_buf): Replace `memmove' with `memcpy' for
	marginal portability gain to older systems.
	* io.c (get_a_record): Ditto.

Sun Nov  2 15:59:27 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h [CONSTVAL]: Renamed from `STRCONST'.
	* eval.c (flags2str): Fix in table.
	(r_tree_eval): For Node_assign_concat, check for the flag for
	both left and right hand sides.  Also add a `force_string' call
	for the right hand side and the left hand side.
	* awkgram.y (yylex): Change flag value for YSTRING and add use
	of flag for YNUMBER.

Wed Oct 29 14:23:29 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h [STRCONST]: New flag value.
	* eval.c (flags2str): Add it to table.
	(r_tree_eval): For Node_assign_concat, check for the flag so that
	we don't clobber string constants given:
		s = ""
		s = s something
	* awkgram.y (yylex): For YSTRING, set STRCONST flag.

Tue Oct 28 18:00:00 2003  Arnold D. Robbins  <arnold@skeeve.com>

	Force SUBSEP to always have a string value. Per bug report
	from mary1john8@earthlink.net.

	* awk.h (NODETYPE): New type, Node_SUBSEP.
	(set_SUBSEP): Add declaration.
	* awkgram.y (isnoeffect, isassignable): Add Node_SUBSPEP case.

	Node_SUBSEP.

Tue Oct  7 09:26:33 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h (NODETYPE): New member `Node_assign_concat'.
	* awkgram.y (exp): Look for case of `x = x y' and if so, create a
	Node_assign_concat.
	* eval.c (interpret): Add case for Node_assign_concat.
	* profile.c (prec_level): Ditto.
	(tree_eval): Ditto.  For variables, call new function `vname' to
	print name; handles varname field for -v variables, which end up
	including the value.
	(vname): New function.

Wed Sep 24 17:32:31 2003  Arnold D. Robbins  <arnold@skeeve.com>

	Speed up `avoid_dfa' kludge, at least a little:

	* awk.h (struct Regexp): Add `has_anchor' member.  Make it and
	`dfa' member shorts; keeps space the same.
	* re.c (make_regexp): Set `has_anchor' member correctly.
	(avoid_dfa): Test for `has_anchor' member instead of searching
	for it each time.

Sun Sep 21 18:34:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (state): Only needs to be 256 bytes, initstate() can't
	use any more than that.  Well whadayaknow.
	(do_rand, do_srand): Call `setstate' after calling `initstate'.

Tue Sep 16 15:44:29 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (interpret): For Node_K_switch, add kludge_need_start stuff
	as used in `match_op'.  Sigh.
	* re.c (make_regexp): Add `no_dfa' variable, which is true if
	GAWK_NO_DFA exists in the environment.  This enables run time
	testing of things with/without the dfa matcher.

Mon Sep 15 18:36:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

	After much soul searching, reinstated old dfa code. The performance
	of the new regex is just disastrous.  Sigh.

	* awk.h (re_cnt): Reinstated old definition.
	(struct Regexp): Added `dfareg' and `dfa' members.
	(make_regexp): New last parameter in function, changed decl.
	(avoid_dfa): Added declaration.
	* awkgram.y (regexp, mk_rexp): Added use of `re_cnt'.  Fixed call
	to `make_regexp'.
	* Makefile.am: Add dfa.h and dfa.c.
	* eval.c (match_op): Complexified: added call to `avoid_dfa' and
	`kludge_need_start' variable where used to pass FALSE as last parameter
	of research().
	* field.c (set_FS): Fixed call to `make_regexp'.
	* io.c (get_a_record, set_RS): Fixed calls to `make_regexp'.
	* re.c (make_regexp): Added last paramter (`dfa') to function.
	Complexified the code.
	(re_update): Fixed call to `make_regexp'.
	(research): Complexified the code, added calls to dfa stuff.
	(dfaerror): New function.
	(re_update): Fixed call to `make_regexp'.
	(avoid_dfa): New function.

Tue Sep  9 15:57:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (get_src_buf): Fix calculation of `offset' when shifting
	source lines around.  In general, improve handling of things when
	moving the source code line around.  What a mess this code is.

Mon Sep  8 19:08:55 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (fmt_ok): Make provision for %F format and printf %'f flag
	here too.

2003-07-23  Christophe Bisiere  <bisiere@univ-tlse1.fr>  (tiny change)

	* posix/regex.h (RE_TRANSLATE_TYPE): Define it to "unsigned char,"
	  to avoid problems at hosts with signed char.
	* posix/regexec.c (re_search_internal): Don't say
	  "unsigned RE_TRANSLATE_TYPE."

Thu Aug 28 11:09:41 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (nextfile): Change use of variable `files' to make it
	clearer that it's a boolean flag.

Tue Aug 26 22:58:15 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (useropen): Add `defined (HAVE_GETGROUPS)' as first test
	in `#ifdef'.  Brings things in sync with same test in main.c and awk.h.

Tue Aug 26 22:49:37 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* dbug.h: New file.

	* array.c, awkgram.y, builtin.c, eval.c, ext.c, field.c, io.c,
	main.c, msg.c, node.c, profile.c, re.c: Converted to use
	Fred Fish's `dbug' library.  By default compiled out, thus
	not affecting speed.

	For the nonce, the `dbug' library itself is not shipped with
	gawk, since I expect no-one else but me to be using it.

Thu Aug 21 23:15:36 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (numfiles): Change extern decl to long, to match what's
	in main.c.  Keeps things working on 64-bit systems.  Thanks to bug
	report from Jan Oravec <jan.oravec@6com.sk>.

Wed Aug 20 14:53:47 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (genflags2str): Move test for out-of-space inside test
	for is the bit set.

Mon Aug 11 11:26:51 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* regcomp.c (parse_bracket_exp): If `build_charclass' fails, just pass
	its value on as the return value.

Sun Aug 10 16:59:14 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* regcomp.c (build_range_exp): Make sure we don't
	get WEOF on range characters.

Tue Aug  5 21:49:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (get_actual): In `case Node_param_list' add test for
	`&& (symbol->flags & FUNC) == 0' to the if.

Sun Jul 13 18:28:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

	Further bug fix:

	* awkgram.y (variable): Give the new variable an lnode
	of Nnull_string if it's not an array, even if it is
	a Node_var_new.

Fri Jul 11 09:32:21 2003  Arnold D. Robbins  <arnold@skeeve.com>

	Bug fix:

	* eval.c (r_tree_eval): For Node_array_ref, set
	tree->orig_array->var_value to Nnull_string too.

	Unrelated i18n and POSIX change:

	* configure.ac: Add check for local printf supporting %F format.
	* awk.h (loc): New variable declaration.
	* main.c (loc): Defined.
	(main): Call `localeconv' to set loc.

	decimal formats (not %e, %E), adds thousand separator into value.

2003-07-10  Paul Eggert  <eggert@twinsun.com>

	* io.c (two_way_open): If /bin/sh cannot be executed, exit
        with status 126 consistently.

Mon Jul  7 11:01:43 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* Release 3.1.3: Release tar file made.

Mon Jul  7 09:55:49 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c (copyleft, usage): Make sure to fflush output fp. Per Jim
	Meyering, if error, exit non-zero.
	* ext.c (get_argument): Fix array paramater handling.

2003-07-06  Paul Eggert  <eggert@twinsun.com>

	* builtin.c (do_substr): Issue better diagnostics when
	d_substr and d_length are NaN, or when 0 < d_length < 1.
	Be careful when comparing double to SIZE_MAX, as
	the comparison might return the "wrong" answer when
	`(double) SIZE_MAX' is a number that is not equal to
	SIZE_MAX.
	(do_gensub): Watch out for HOW values that are out of range
	or are NaN.
	(do_dcngettext): dcngettext wants an argument of type
	unsigned long, not long, so use a value of that type.

Fri Jul  4 10:58:02 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c (main): Make option letter 'D' fall through into default
	unknown case if not debugging. Let's us have just one version of
	`optlist'.

Thu Jun 26 15:25:57 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (get_actual): Undo Stepan Kasal change of 2003-06-17.
	See test/match2.awk.

Wed Jun 25 15:26:08 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (do_rand): Change calculation so that result
	obeys constraint:  0 <= N < 1.  This is per history and POSIX.
	Thanks to Nelson Beebe (beebe@math.utah.edu) for reporting
	this issue.

Mon Jun 23 15:13:39 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (rs1scan): Per advice from Bruno Haible, it's safe
	to skip the multibyte checking code if RS is '\n'. See
	the comment in the code.  Big performance improvement for
	multibyte locales.

2003-06-20  Stepan Kasal  <kasal@ucw.cz>

	* eval.c (comp_func): if memcmp returns 0, we have to compare
	  the lengths.

2003-06-19  Stepan Kasal  <kasal@ucw.cz>

        * eval.c (interpret) <Node_K_arrayfor>: use NULL, not 0, to
          initialize the variable list.
          (comp_func): array indices no longer are string values,
          you have to use ahname_str, ahname_len.

Tue Jun 17 11:53:46 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (get_actual): Make check for isparam
	smarter: also check for FUNC flag.

2003-06-17  Stepan Kasal  <kasal@ucw.cz>

        * array.c (get_actual): even if canfatal is FALSE, don't
          tolerate existence of things which can't happen.

Mon Jun 16 16:21:44 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* configure.ac: Removed m4/Makefile.
	* m4/Makefile.am: Removed.

2003-06-16  gettextize  <bug-gnu-gettext@gnu.org>

	* configure.ac (AC_OUTPUT): Add m4/Makefile.
	(AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.

Sun Jun 15 20:45:43 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (get_a_record): Enhance logic to fill buffers to include
	`|| no_data_left(iop)'.
	(rs1scan): Fix logic for setting recm fields for multibyte
	character case.

2003-06-10  Stepan Kasal  <kasal@ucw.cz>

	* awkgram.y (release_all_vars): do not try to release a value of
	  Node_var_new; after get_lhs, use the lhs directly, do not try
	  to do (*lhs)->var_value; the Node_var case doesn't need
	  special treatment.
	* builtin.c (do_match): `get_param' is successful iff it returns
	  Node_var_array---if the variable was new, get_param has already
	  changed the type.
	* field.c (do_split): likewise.

Sun Jun 15 19:36:35 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* node.c (r_dupnode): Typo fix in hash tables: stptr -> ahname_str.
	Thanks to mary1john8@earthlink.net.
	* array.c (get_actual): Add `if (canfatal)' before call to
	`cant_happen'.

Sun Jun 15 19:25:49 2003  Patrick T.J. McPhee   <ptjm@interlog.com>

	* awk.h (memcpy_ulong): Add ! WIN32 to ifdefs.

Mon Jun  9 18:38:20 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* custom.h (hpux): Added stuff to (hopefully) get `tzset'
	declared on HP/UX 10 and up.

Mon Jun  9 17:12:24 2003  Patrick T.J. McPhee   <ptjm@interlog.com>

	* awk.h (ATTRIBUTE_EXPORTED): New macro for dynamic libs on Windows32.
	* CONVMFTidx, stack_ptr, do_lint, lintfunc: Now have this attribute.

Mon Jun  9 13:11:33 2003  Arnold D. Robbins  <arnold@skeeve.com>

	Clean up of Stepan's patches.

	* array.c (get_actual): Renamed from r_get_array. Added second
	param canfatal if routine should print fatal message when not an array.
	(get_actual): Renamed 'prm' to `isparam'.
	(array_vname): Add static msglen var; only realloc string if it grows.
	Don't use `s += sprintf(...)'. No good on old systems where sprintf
	returns char *.  Minor formatting cleanups.
	(do_adump): Restored separate `a' and `r' variables; helps for debugging.

	* awk.h (SCALAR, UNINITIALIZED): Removed entirely, renumbered other flags.
	(get_array, get_param): New macros, calls get_actual.
	(get_actual): Declaration changed from that of r_get_array.

	* awkgram.y (release_all_vars): Restored previous version of code; new
	version isn't right for Node_xx variables.
	(variable): Minor code cleanup for readability.

	* builtin.c (do_match): Use get_param and print our own message when
	third parameter is not an array.

	* eval.c: Added a few comments here and there, removed some no longer
	needed comments.

	* field.c (do_split): Use get_param and print our own message when
	second parameter is not an array.

Mon Jun  9 11:46:21 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (do_delete): Initialize hash1 and last to keep gcc -Wall happy.
	* io.c (rsnullscan): Comment out label skip_leading for same reason.

Wed May 28 08:31:23 CEST 2003  Stepan Kasal  <kasal@math.cas.cz>

	* eval.c (forloops_active, in_function): Nuked.
	(pop_all_forloops, pop_fcall_stack): are now inline.

Wed May 28 07:58:35 2003  Stepan Kasal  <kasal@math.cas.cz>

	* field.c, awk.h (Null_field): no longer static.
	* field.c (init_fields): initial value of $0 can be Nnull_string,
	  no need to copy it.
	* eval.c (r_get_lhs) <Node_field_spec>: test for uninitialized field,
	  which is Nnull_string for $0 and Null_field for $(>0).
	* builtin.c (do_print_rec): test for uninitialized $0.

Tue May 27 17:03:02 2003  Stepan Kasal  <kasal@math.cas.cz>

	* awk.h (Node_var_new): New node type for variables which can be
	either scalar or array.  From now on, Node_var is always scalar.
	(Node_gvar_ref): Nuked, its role can be taken by Node_array_ref.
	(orig_var): removed, orig_array is enough.
	(SCALAR, UNINITIALIZED): Flags nuked.
	(var_uninitialized): new macro to distinguish uninitialized vars;
	used in several other macros.
	* array.c (r_get_array, array_vname, do_adump): adapt to the
	above changes.
	* awkgram.y, eval.c, field.c, main.c, node.c, profile.c: ditto.

Tue May 27 14:27:50 2003  Stepan Kasal  <kasal@math.cas.cz>

	* array.c (r_get_array): New function, which goes all the way
	through Node_param_list to actual Node_var_array; if it encounters
	non scalar Node_var, it changes it to Node_var_array.
	(in_array, do_delete, do_delete_loop, do_adump, assoc_sort_inplace):
		Use get_array.
	(assoc_lookup): The parameter must be a Node_var_array.
	* awk.h (get_array, r_get_array): Declare the new function and define
	a macro to speed it up.
	* builtin.c (do_match): Use get_array.
	* eval.c (interpret) <Node_K_arrayfor>: ditto.
	(r_get_lhs) <Node_K_arrayfor>: ditto.
	* field.c (do_split): ditto.

Tue May 27 08:23:51 2003  Stepan Kasal  <kasal@math.cas.cz>

	Changed node->vname meaning for type Node_array_ref and Node_gvar_ref.
	It contains only the reference name; one has to (recursively) follow
	node->prev_array to find out the call history for the array.

	* array.c (array_vname): New function to print the array name.
	(assoc_lookup, do_delete): Use array_vname.
	* eval.c (interpret, r_tree_eval, r_get_lhs): Use array_vname.
	(push_args, pop_fcall): Things have simplified.
	* awk.h (array_vname): Declare.
	(prev_array): Define.

Sun Jun  8 11:25:36 2003  Stepan Kasal  <kasal@ucw.cz>

	* awkgram.y (append_right): when using savetail, remember that it
	is not necessarily the tail of the list---it's just a pointer to
	the last chunk appended.

Thu Jun  5 12:01:41 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (do_strtonum): Make `strtonum(13)' work.

Wed Jun  4 17:07:06 2003  Corinna Vinschen  <vinschen@redhat.com>

	* io.c (binmode): Include function for __CYGWIN__ too.

Tue Jun  3 12:40:50 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (interpret): Node_K_switch.  For regex case, don't
	call `free_temp' on the result of `force_string' if it's equal to
	switch_value. Thanks to John DuBois <spcecdt@armory.com>
	for finding the problem.

Sun Jun  1 13:08:22 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (format_tree): For %c, force precision to 1.

Wed May 28 11:55:48 2003  Arnold D. Robbins  <arnold@skeeve.com>

	switches in both functions.

Wed May 28 11:38:59 2003  Stepan Kasal  <kasal@math.cas.cz>

	* awkgram.y (switch_body): remove rule ``switch_body:/*empty/''
	as ``switch_body:case_statements'' covers it---this disambiguation
	fixes a reduce/reduce conflict.

Sun May 25 16:23:43 2003  Corinna Vinschen  <vinschen@redhat.com>

	* configure.ac: Remove linking against /usr/lib/automode.o.
	* configure: Regenerate.

Sun May 25 15:19:19 2003  Stepan Kasal  <kasal@math.cas.cz>

	* awk.h (get_lhs): For an initialized Node_var, you may return
	the address of var_value pointer, no matter whether reference
	bit was set or not.  We were silly slowing down most of the
	assignements.

	* (get_a_record): after grow_iop_buffer, move recm.rt_start even
	if recm.len == 0.

Mon May 19 16:55:59 2003  Arnold D. Robbins  <arnold@skeeve.com>

	Code for C-style switch statements. Initial version contributed by
	Michael Benzinger <Michael.Benzinger@sabre-holdings.com>.

	Disabled by default, use `configure --enable-switch' to turn it on.

	* configure.ac: New AC_ARG_ENABLE for switch statements.
	* awk.h (NODETYPE): New types for switch, case, default keywords
	and respective lists.

	avoid duplicate cases.
	* eval.c (nodetypes): New entries for new NODETYPEs.
	(interpret): New code to do switch execution.
	* profile.c (pprint): New code to print switch statements.

Mon May 19 15:05:43 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* configure.ac: Renamed from configure.in.
	* fixvers: Now looks in configure.ac.
	* Makefile.am: Now cites configure.ac.

	* Misc other: Updated to Automake 1.7.5.

Sun May 18 12:03:56 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (do_delete_loop): Fix bracing of logic for
	tests.

Wed May 14 09:01:16 2003  Stepan Kasal  <kasal@math.cas.cz>

	Misc patches:

	* builtin.c (do_match): if third parameter to `match' is supplied,
	store all subexpressions which are applicable, even though there
	are some unused between them.

	* awkgram.y (yylex): when returning from unterminated REGEXP
	(which is /* kludge */), take care to fake a yylval, to
	prevent ``internal error'' later.

Sun May 11 15:51:00 2003  Stepan Kasal  <kasal@math.cas.cz>

	* io.c (rsnullscan, get_a_record): Boundary condition bug fixes.

Sun May 11 15:15:20 IDT 2003  Scott Deifik  <scottd@amgen.com>

	* awk.h: Add decls for `memcpy_ulong', `memset_ulong', and
	MSC defines.
	* regex.c: Include <stdio.h> if MSC for size_t.

Mon May  5 15:11:06 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (get_a_record): Only tweak RT's value in place if the current
	RS scanner is the same as the last one. Bug report submitted by
	John DuBois (<spcecdt@armory.com>).

Fri May  2 14:39:48 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (get_a_record): Add logic at end to be smart about setting
	RT.  Saves considerable time, esp for default case where RS = "\n".

Wed Apr 30 11:44:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* field.c (do_split): Add check and code for Node_gvar_ref.
	* array.c (in_array, do_delete, asort_actual): Same.
	* builtin.c (do_split): Same for 3rd arg array parameter.

	* awk.h (IOBUF): Removed total field, no longer used.
	* io.c (at_eof, has_data, no_data_left): New macros.
	(RECVALUE, SCANSTATE): New enumerated types.
	(rs1get_a_record, rsnull_get_a_record, rsre_get_a_record): Removed.
	(get_a_record): Rewritten, again. Now contains just buffer and
	record code; searching code moved into these functions:
	(rs1scan, rsnullscan, rsrescan): New functions to scan a buffer
	for record contents and terminator. Fill in values in:
	(struct recmatch): Holds found record and terminator.
	(spec_setup): Set iop->dataend to indicate data is already in buffer.
	(nextfile, inrec): Use new macros instead of flag and pointer tests.
	(set_RS): Set scanning function instead of record function.

	FWIW, it all passes `make test'.

Sun Apr 27 21:02:39 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (do_close): At end, if do_posix return 0. See comment in code.

	Thanks to Kimura Koichi <kimura.koichi@canon.co.jp> for reporting.

Sun Apr 13 16:02:10 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c (main): Add call to `setlocale' for LC_NUMERIC after program is
	parsed.
	(arg_assign): Switch back to "C" locale for LC_NUMERIC for command
	line assignments; this is per POSIX that period is decimal point for
	program and command line assignments and the locale's separator
	applies for input, output, and string to number conversion.

2003-03-26  Paul Eggert  <eggert@twinsun.com>

	* builtin.c [HAVE_INTTYPES_H]: Include <inttypes.h>.

	(TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): New macros, taken from
	coreutils and many other GNU utilities.
	(format_tree): When formatting, use widest possible integers
	rather than settling with 'long'.
	(do_lshift, do_rshift, do_and, do_or, do_xor, do_compl): Likewise,
	when doing bitwise operations.
	* configure.in (jm_AC_TYPE_LONG_LONG, jm_AC_TYPE_UNSIGNED_LONG_LONG,
	jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Add, since the mainline
	code now needs this.
	* doc/gawk.texi (Control Letters, Bitwise Functions): Document this.
	* m4/intmax_t.m4: New file, taken from coreutils (but renamed to
	avoid collision with our m4/inttypes.m4).
	* m4/longlong.m4: New file, taken from coreutils.
	* m4/uintmax_t.m4, m4/ulonglong.m4: Remove; superseded by the above
	new m4 files.

        * builtin.c (BITS_PER_BYTE): Remove; use CHAR_BIT instead, since
        it's the standard name.
        (do_lshift, do_rshift): Complain if the shift width is exactly equal
        to the word size, too.

Thu Mar 27 10:44:11 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (rs1_get_a_record, rsnull_get_a_record, rsre_get_a_record):
	Enhance check for no data left in file to be only if file has
	non-zero size.  Linux files such as /proc/filesystems stat as a
	regular file of size 0, but actually have contents. Ugh.
	Thanks to Martin Schlemmer <azarah@gentoo.org> for the bug report.

Wed Mar 26 12:19:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

	a syntax error.
	(isarray): New function, tests if a symbol can be an array.

	* custom.h: Add check for HP/UX, needed for GCC.

Mon Mar 17 09:21:09 2003  Arnold D. Robbins  <arnold@skeeve.com>

	Allow simultaneous manipulation of a global array directly
	and when passed as a parameter.

	* awk.h (Node_gvar_ref): New nodetype.
	[orig_var]: New macro.
	* array.c (do_delete_loop, do_delete): Add logic to handle
	seeing Node_gvar_ref.
	* eval.c (nodetypes): Add Node_gvar_ref.
	(r_tree_eval, r_get_lhs): Add Node_gvar_ref case.

Wed Mar 19 14:08:11 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y: Production `program --> program error'. Add a return so
	that we don't produce an infinite stream of error messages.
	Thanks to Michael Mauch <michael.mauch@gmx.de> for pointing this out.

Wed Mar 19 13:45:50 2003  Corinna Vinschen  <vinschen@redhat.com>

	* regex.c [RE_ENBABLE_I18N]: remove definition; the one in
	regex_internal.h is better and makes things work with Cygwin.

Tue Mar 11 11:54:20 2003  Arnold D. Robbins  <arnold@skeeve.com>

	* regex_internal.h: Don't include <limits.h> after <regex.h> was
	included in regex.c, since it could redefine RE_DUP_MAX to a lower
	value.
	(bitset_set, bitset_clear, bitset_contain): Use 1UL instead of 1 in
	left shift operations.
	* regex.c: Include <limits.h> before <regex.h>
	* regcomp.c (re_compile_fastmap_iter, init_word_char, parse_expression):
	Use 1UL instead of 1 in left shift operations.

	VMS diagnostic.

Thu Feb 27 17:48:29 2003  Pat Rankin  <rankin@pactechdata.com>

	* regexec.c (proceed_next_node): Cast re_string_get_buffer to char *.

	and rp for do_print{,f,_rec} functions.
	(do_print): Use redirect_to_fp().
	(do_printf): Use redirect_to_fp().
	(do_print_rec): New function to just print $0 from field_arr[0]

	  (start, program, rule): no value associated,
	  expression_value is now treated similarily as begin_block and end_block.
	  (pattern, rule): bison actions for non-terminal `pattern' now
	  add a new rule to the appropriate Node_rule_list, action for
	  non-terminal `rule' now only adds the associated code block

	  (io_allowed): renamed to !begin_or_end_rule.
	  (append_pattern): New function, adds new Node_rule_node to a rule_list.

        values for lint messages, so they should be printed pretty
        much as the user saw them.  Check for overflow before
        converting floating point to integer.  Do the right thing with
        NaNs.

        Check for index out-of-range before checking for length
        out-of-range, to avoid some nasty effects if address
        arithmetic overflows (e.g., indx + length < index).

	Allow zero-length substrings when checking for lint if
	do_lint == LINT_INVALID.

Mon Oct 28 13:21:20 2002  Arnold D. Robbins   <arnold@skeeve.com>

	Applied lots of patches from Stepan Kasal, tweaked as needed
	for current code base.

	* node.c (dupnode): When n->stref overfows, flag the node as PERM.
	Same for n->ahname_ref.
	(unref): Remove the check for n->stref == LONG_MAX and
	n->ahname_ref == LONG_MAX.
	* awk.h (make_string): The third argument to make_str_node changed
	from FALSE to 0, it's not Boolean.
	(free_temp): Evaluate the argument only once, so that we
	can call free_temp(tree_eval(n)) for achieving side effects.
        (load_environ, load_procinfo): Changed return type to NODE *.
        * main.c (load_environ): The ENVIRON_node should be created with type
	Node_var_array and lnode set to NULL.  Return pointer to the created node
	and create an empty hash even on TANDEM.
	(load_procinfo): Same mods for PROCINFO_node.
	(init_args): ARGV_node should also have lnode set to NULL.
        * eval.c (r_tree_eval): case Node_assign moved just above the other
	assignment cases.
	(op_assign): ++ and -- cases merged with += and -=, respectively.
	(push_args): Evaluate all args, even in cases where more args are
	supplied then required.
	(interpret): In case Node_K_forarray, flag the variable
	num_elems also as volatile, so that it survives longjmp() and
	can be trusted when linting code.
	(r_get_lhs): Case Node_param_list was unreachable (unless
	something breaks really badly), remove it;
	(r_tree_eval): case Node_var_array removed from the last switch,
	it was caught in the first switch above.
	* profile.c (tree_eval): Again, case Node_var_array was caught above.
        * awkgram.y (variable): Code simplified, making use of the above
        changes.
	* field.c (sc_parse_field): IGNORECASE only applies to regex based
	field-splitting, so remove code that pays attention to it.
	(do_split): Don't use parse_field if RS_is_null.
	(set_FS): Beware of FS == "\\" even if RS_is_null.

	Code changes to make things work better:
	* field.c (set_FS): Don't use cmp_nodes() to compare old and new
	value of FS, that uses IGNORECASE, which is a bad idea. Improve
	logic for choosing sc_parse_field.  Ensure that when RS_is_null
	but using a single character, that we do pay attention to
	case when doing regex splitting.
	* io.c (set_RS): Don't use cmp_nodes() to compare old and new
	value of RS, that uses IGNORECASE, which is a bad idea.

Mon Oct 28 09:43:14 2002  Arnold D. Robbins   <arnold@skeeve.com>

	* recomp.c (parse_expression): Change return statement into
	two so it'll compile for SGI cc.

	* awk.h (STR, CUR): Changed to STRCUR and NUMCUR respectively,
	to avoid conflict with STR on some System V systems.  Changed
	in all source files.

Thu Oct 24 16:14:34 2002  Arnold D. Robbins   <arnold@skeeve.com>

	* array.c (AVG_CHAIN_MAX): Now a variable, to allow easy experimentation.
	(array_init): Pulls a new value from env var AVG_CHAIN_MAX if it
	exists and sets the variable.
	* awk.h: Add declaration for array_init().

2002-10-11  Isamu Hasegawa  <isamu@yamato.ibm.com>

	* regcomp.c (re_compile_fastmap_iter): Remove the handling

	(regfree): Likewise.
	(create_initial_state): Likewise.
	(analyze): Remove the substitutions which became useless.
	(calc_first): Likewise.
	(calc_epsdest): Use edests of OP_BACK_REF in case that it has
	epsilon destination.
	(duplicate_node_closure): New function.
	(duplicate_node): Remove the handling OP_CONTEXT_NODE.
	(calc_inveclosure): Likewise.
	(calc_eclosure): Likewise.
	(calc_eclosure_iter): Invoke duplicate_node_closure instead of
	direct invocation of duplicate_node.
	(parse): Don't use comma operator in the return to avoid compiler
	warning.
	(parse_reg_exp): Likewise.
	(parse_branch): Likewise.
	(parse_expression): Likewise.
	(parse_sub_exp): Likewise.
	(parse_dup_op): Likewise.

	which became useless.

	(create_cd_newstate): Likewise.
	* posix/regex_internal.h (re_token_type_t): Remove the obsolete type.
	(re_token_t): Likewise.
	(re_dfa_t): Likewise.
	(re_node_set_remove): New macro.
	* regexec.c (check_matching): Remove the handling
	OP_CONTEXT_NODE.
	(check_halt_node_context): Likewise.
	(proceed_next_node): Likewise.
	(pop_fail_stack): Fix the memory leak.
	(set_regs): Likewise.
	(free_fail_stack_return): New function.
	(sift_states_backward): Fix the memory leak.  Remove the handling
	OP_CONTEXT_NODE.
	(update_cur_sifted_state): Append some if clause to avoid redundant
	call.
	(sub_epsilon_src_nodes): Use IS_EPSILON_NODE since it might be a
	back reference.
	(check_dst_limits): Remove the handling OP_CONTEXT_NODE.
	(check_subexp_limits): Likewise.
	(search_subexp): Likewise.
	(sift_states_bkref): Likewise.

	(sift_ctx_init): Add initializing.

Tue Oct 15 14:18:53 2002  Arnold D. Robbins   <arnold@skeeve.com>

	* eval.c (set_IGNORECASE): Call set_RS() instead of
	set_FS_if_not_FIELDWIDTHS().  The former calls the latter
	for us, and also makes IGNORECASE affect RS like it's supposed to.
	* field.c (FS_re_yes_case, FS_re_no_case): New variables.
	(set_FS): Smarten up routine to not recompile FS_regexp if all
	that's changed is IGNORECASE or if switching back to FS from
	FIELDWIDTHS.  Significant speed-up for cases where IGNORECASE
	is assigned to for every record.
	* io.c (RS_re_yes_case, RS_re_no_case): New variables.
	(set_RS): Similar changes as to set_FS().  In particular,
	IGNORECASE changing now affects record splitting too.
	* re.c (refree): Set rp->pat.tranaslate to NULL. It comes
	from casetable and shouldn't be freed. (Strictly necessary
	only for old regex, but a good idea anyway).
	Also, call regfree(& rp->pat) instead of manually free()ing
	things, since there's dynamically allocated stuff hiding in
	the buffer. Avoids a memory leak.

Mon Oct 14 12:02:39 2002  Arnold D. Robbins  <arnold@skeeve.com>

	Major space reduction in array management.  Overhead reduced
	to two NODE's per element from three.

	(ahname_len): new member, points into hash union.
	(ahname_ref): new member, points into hash union.
	* array.c: Replaces uses of ahname member with string and
	length.  Set the reference count correctly to 1 on new nodes.
	* eval.c (interpret): Case for Node_K_arrayfor.  dupnode() the
	array indices, and set loop variable to new value made via
	make_string().
	* node.c (unref, dupnode): Node_ahash nodes are now also
	reference counted, a la strings.  Similar code is used to
	increment/decrement the counts, and/or copy nodes as
	needed.

	Unrelated:
	* awk.h (forsub): Removed. Not used.

Sun Oct 13 16:58:27 2002  Stepan Kasal  <kasal@math.cas.cz>

	* profile.c (pprint): #undef the temporary defines at the end
	of the case.
	* eval.c (interpret): Likewise.

	Also, move the check for NF < 0 from here ...
	* field.c (set_NF): ... to here.
	* main.c (varinit): no need to call set_NF().
	* awkgram.y (statements): don't be so generous when concatenating
	`statements' with a `statement'.

	with a comment that it's internally the same as `delete array'.
	* eval.c (Node_K_delete_loop): Increment the exec_count. Ooops.
	* configure.in (AM_GNU_GETTEXT_VERSION): New macro call.

Thu Oct 10 16:39:51 2002  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h (vname, exec_count): Now macros into different

	macro.
	* main.c (lintfunc): Made ifdefed decls match awk.h.
	* eval.c (comp_func): Use memcmp instead of strcmp.

Tue Sep 10 17:33:48 2002  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (statement): moved delete, print, and expressions into
	  new non-terminal `simple_stmt'.  Allow opt_simple_stmt in the

Sun Nov 18 11:56:01 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* random.c (srandomdev): ifdef-out.  Lots of compile time

	  use the routine.  The heck with fine-grained solutions.

Wed Nov 14 16:12:40 2001  Pat Rankin  <rankin@eql.caltech.edu>

	* builtin.c (bchunk_one): Use `ofre < 1' instead of `ofre <= 0'
	  to avoid compiler complaint about suspicious comparison for
	  unsigned variable.  (`ofre == 0' ought to suffice...)

Tue Nov 13 17:27:52 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (yyerror): Fix the code to behave like it
	  used to.  Keep "no arbitrary limits" by mallocing the

Sat Nov  3 22:27:21 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* m4/strtod.m4: Add missing `#endif'. Oops.

Mon Oct 29 14:53:57 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y: Add semicolons in calls to count_args().
	  Apparently bisoon adds a semicolon to each body

	* builtin.c (format_tree): Fix off-by-one error in "ran out

	* io.c (iop_open): Only call os_close_on_exec() for
	  fd > fileno(stderr).

2001-09-07  Paul Eggert  <eggert@twinsun.com>

        * io.c (redirect): When deciding to use the fdopen bug hack,
          use "__sun" rather than "solaris".  No compilers predefine
          "solaris", but both GCC and Sun C predefine "__sun".

Thu Aug 30 15:17:12 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c (copyleft): Use a printf %d for last year of update
	  to avoid translation strings changing when the file
	  is updated from now on.  Suggestion from Ulrich Drepper.

Thu Aug 23 14:01:14 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* awkgram.y (unary minus production): Add check that value
	  isn't a string. Based on bug report from drj@pobox.com.
	* profile.c (tree_eval): For node_val, only test NUMBER

	* po/fr.po, po/tr.fo: New files.

2001-08-13  Paul Eggert  <eggert@twinsun.com>

	This patch fixes a bug that causes gawk to rewind standard
	input incorrectly.  It also removes all instances of fseek,
	from the gawk source proper, which should make gawk a bit
	more portable.

	(The original patch removed off_t & lseek too, but I need
	that for something else. ADR.)

	* posix/gawkmisc.c (optimal_bufsize):
	Don't use lseek on the input, because that might change
	its state.  Instead, just check whether it is a regular file.
	This obviates the need to invoke isatty.
	(Also, fix a spelling error in the first line of the source.)
	* pc/gawkmisc.pc, unsupported/atari/gawkmisc.atr: Likewise.

	* awk.h (S_ISREG): Move this macro here ...
	* io.c (S_ISREG): from here.

Fri Aug  3 13:38:54 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (assoc_lookup): Change assert test on type to real test
	  to protect against FS[1] = "x" kinds of things.  It'd be better
	  to do this in the grammar, but this is easier and just as
	  effective.

	Undid BECAMEARRAY changes of 25 June 2001 in favor of correct code:
	* eval.c (pop_fcall): Change test and comment for freeing n->vname.
	  (flags2str): removed BECAMEARRAY entry.
	* awk.h (BECAMEARRAY): Removed define.
	* array.c (assoc_lookup): Removed setting of BECAMEARRAY flag.

Mon Jul 23 17:33:13 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (get_a_record): Handle case where RS = "" and input file
	  is only newlines.  See test/onlynl.   Bug report by
	  Michel Jouvin <jouvin@lal.in2p3.fr>.

Wed Jul  4 18:34:19 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (assign_val): Don't allow negative values for NF.
	* field.c (set_NF): Robustify field-freeing code to make sure
	  values are always positive.

Sun Jul  1 19:15:01 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (do_index): If second string is "", return 1.

Mon Jun 25 19:34:24 2001  Arnold D. Robbins  <arnold@skeeve.com>

	* re.c (re_update): Add assertion that type is Node_regex when flags
	  indicate CONST.

	New lint warning.
	* awkgram.y (yylex): Added lint warning that constant with leading
	  zero is treated as octal or hex.

	Generalized code for those who are Strong In The Ways of the Source.
	* awk.h: New boolean variable.
	* main.c (main): set it.
	* eval.c (interpret): For arrays, check it. Remove variable 'first',
	  not needed anymore.
	* profile.c (pp_string_fp): Enable printing of non-ascii characters
	  verbatim if variable set.

	Fix memory corruption on SCO for array vars as params changed globally.

	* Release 3.1.0: Release tar file made.  And there was
	  rejoicing.

	  problems.

Mon Apr 23 10:26:38 2001  Arnold Robbins  <arnold@skeeve.com>

	* awkgram.y: Fix grammar so that `print ... |& ".." |& getline'

	  based on bug report in bug.gnu.utils by aaronl@vitelus.com
	  (Aaron Lehmann).
	* awk.h: Fix logic around include of <sys/types.h>.

Thu Apr  5 20:12:05 2001  Pat Rankin  <rankin@eql.caltech.edu>

	* dfa.c: for VMS, #include <stddef.h> instead 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.

	* 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
	  a warning, not a fatal error.  Breaks too many things.

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>

	* m4: New directory.
	* acinclude.m4: Removed, replaced by m4/*.m4.

	  and save space.
	* node.c (more_nodes): move setting of exec_count to
	  #ifndef NO_PROFILING.

	* 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.

	  New features for profiling:
	* awk.h (NODE): add `exec_count' member.

	  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

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

	* 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

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

	* 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.

	  (two_way_open): new function.

Sat Dec 13 21:15:07 1997  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h (struct node): new member, `param_list' in union `x', becomes
	  `node->parmlist' in the code.
	* awk.y (func_install): rearranged a bit, to build up a list of
	  the function parameter names and to save it in the `parmlist' field.
	* eval.c (push_args): new parameter, `varnames', which is the list
	  of variable names.  Use this to set the vname field of each
	  parameter's value as it's created. Special case arrays to include
	  where they came from, mainly for array vs. scalar diagnostics.
	  (r_tree_eval): don't set the `vname' field for parameters.
	  (pop_fcall): free the `vname' field if it's an array.
	  (func_call): pass in the `parmlist' field to call of push_args().

	* builtin.c (format_tree): Workaround a DEC C V5.7 bug by
	  splitting `strcpy() + 3' into two expressions (the builtin

Mon Mar 20 16:18:34 2000  Arnold D. Robbins  <arnold@skeeve.com>

	* io.c (set_RS): Added a lint warning about multicharacter RS,
	  per suggestion from Akim DeMaille (akim@epita.fr).

Sun Feb 13 14:40:32 2000  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (push_args): Fix from Nide Naoyuki <nide@ics.nara-wu.ac.jp>,

Sun Feb  6 11:39:33 2000  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (op_assign):  Fix it right.  For ++ and --, get the lhs
	  in the operations, do the op, and then return.  For += etc,
	  get the rhs FIRST, since the lhs can move around as a result,
	  *then* get the lhs and do the operation. See test/opasnidx.awk.

Tue Feb  1 18:41:40 2000  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (op_assign): reget the rval after regetting

Thu Jan 27 18:06:31 2000  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.y (yylex): Made ']' not one of the characters
	  that sets `want_assign' to false.  `a[i] /= 2' was
	  broken.  Per bug report from Kristofer T. Karas
	  <ktk@ktk.bidmc.harvard.edu>.

Wed Dec 22 15:06:37 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.y: Removed declarations of functions before
	  definition of `tokentab[]'.  They're redundant with
	  what's in awk.h.

Thu Dec  9 17:01:07 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* node.c (parse_escape): Add lint warning for unrecognized
	  escape sequences.

	  doc, instead.

Thu Dec  2 13:08:18 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (do_compl): test `d' for negative inside the do_lint
	  test, not uval.  Ooops.

Fri Nov 26 10:58:36 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (assoc_find):  ALWAYS compare indexes as strings,
	  don't use cmp_nodes in case they are numeric.  Oh my.
	  Talk about a Day 1 bug!

Tue Nov 23 11:58:53 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* regex.c (SYNTAX): cast argument to `unsigned char' instead of
	  &-ing with 0xFF.  Hopefully somewhat more portable, ala 21 Nov 99
	  changes to awk.y.

Sun Nov 21 22:25:27 1999  Paul Eggert  <eggert@twinsun.com>

	* aclocal.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a
	  problem with the QNX 4.25 shell, which doesn't propagate exit
	  status of failed commands inside shell assignments.

Sun Nov 21 20:33:35 1999 Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h (nextc): remove declaration, don't need it here.
	  awk.y (nextc): Cast values to unsigned char so that latin-1
	  characters in strings don't turn themselves into EOF.
	  Most notably y-umlaut, which is decimal 255.

Mon Nov  1 20:00:25 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* regex.c (init_syntax_once): move below definition of
	  ISALNUM etc., then use ISALNUM to init the table, so that
	  the word ops will work if i18n'ed.
	  (SYNTAX): And subscript with 0xFF for Latin-1 characters.

Mon Oct 25 18:37:13 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* awk.h, main.c, io.c: undo previous changes (22 Oct 1999).
	* main.c (main): move call to `init_fields()' to before
	  arg parsing.  This allows `-v NF=blah' to work ok.

Fri Oct 22 17:43:40 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c (arg_assign): Add new arg, `initing' for icky special
	  casing of -v of special variables.  Use it to check for NF.
	  May need to add other cases later.
	  (pre_assign): change call arg_assign, passing initing=TRUE;
	  io.c (nextfile): change call arg_assign, passing initing=FALSE;
	  awk.h: Change prototype for arg_assign.

Tue Oct 19 16:06:48 1999  Paul Eggert  <eggert@twinsun.com>

	* io.c (close_redir): Don't munge errno between setting it and
	  using it.

Wed Oct  6 17:47:47 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* main.c (arg_assign): return NULL on bad variable.  Allows
	  things like `./3x=stuff' to work as a filename.

Thu Sep 23 21:35:46 1999  Paul Eggert  <eggert@twinsun.com>

	* aclocal.m4 (GAWK_AC_SYS_LARGEFILE_FLAGS): Work around GCC
	  2.95.1 bug in HP-UX 10.20 or later. (Had to fix the fix. ADR. :-)

Tue Sep 21 13:31:36 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* builtin.c (format_tree): For '0', only set zero_flag if we
	  haven't seen the field width or precision yet.

Mon Aug  9 13:06:01 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* array.c (assoc_lookup): Removed code that gave each array
	  a private copy of each index.  Balloons memory usage for
	  no good reason that I can see.  Just use dupnode in all
	  cases.
	* configure.in: check for $srcdir/.developing adds extra
	  defines for my testing/debugging use.  Yes, hack alert.

Sun Aug  1 11:02:02 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* node.c (dupnode): turn off FIELD when copying nodes.
	* array.c (do_adump, assoc_dump): new functions for array debugging.

	  variable inside the function.

Sun Jul  4 16:53:14 1999  Arnold D. Robbins  <arnold@skeeve.com>

	* eval.c (eval_condition): add extra braces to avoid
	  gcc warning.  I'm not going to bother for the library
	  code like dfa and regex.

Wed Jun 30 16:14:36 1999  Arnold D. Robbins  <arnold@gnu.org>

	* Release 3.0.4: Release tar file made.  This time for sure.

Wed Jun 30 16:10:11 1999  Arnold D. Robbins  <arnold@gnu.org>

	* awk.h: add include of <assert.h>, and comment about config.h
	  having to be included before any system headers.  Otherwise,
	  with egcs-2.91.66 and later on Linux systems, and possibly
	  others, things break badly, due to the LFS macros.
	* awk.y, builtin.c, eval.c, field.c, io.c: removed include
	  of assert.h

Wed Jun  9 11:39:19 1999  Paul Eggert  <eggert@twinsun.com>

	  Add support for AIX and HP-UX.
	  (GAWK_AC_SYS_LARGEFILE_FLAGS, GAWK_AC_SYS_LARGEFILE_SPACE_APPEND,
	  GAWK_AC_SYS_LARGEFILE_MACRO_VALUE): New macros.

	* acconfig.h (_FILE_OFFSET_BITS, _LARGEFILE_SOURCE, _LARGE_FILES):
	  New macros.

	* Makefile.in (MISC): add config.guess and config.sub so they get
	  included in the distribution.

Wed Jun  9 11:29:29 1999  Paul Eggert  <eggert@twinsun.com>

	* io.c (iop_alloc): Don't mmap files whose sizes don't fit in `int'.
	  [ This isn't really needed, as HAVE_MMAP is #undef'ed at the top,
	  but it's there in case people want to take their life in their hands. ]

Sun Jun  6 11:28:07 1999  Arnold D. Robbins  <arnold@gnu.org>

	* BETA Release 3.0.46: Release tar file made.

	  zero precisions and zero values used with the `#' flag.
	  Thanks to Andreas Schwab (schwab@gnu.org) for pointing these out.

Wed May 19 14:02:54 1999  Arnold D. Robbins  <arnold@gnu.org>

	* io.c (do_close): move test for `close(FILENAME)' to after
	  loop through all open redirections. Fixes problems in obscure
	  cases with redirections in END rules.

Sun May 16 14:08:39 1999  Arnold D. Robbins  <arnold@gnu.org>

	* awk.y (yylex): fix group of characters including ',' to

	  case.

Tue May 11 16:48:11 1999  Arnold D. Robbins  <arnold@gnu.org>

	  from the front of records when RS = "" and there's only one
	  newline at the front of the file, which the regex didn't catch.

Wed Apr 28 12:27:49 1999  Arnold D. Robbins  <arnold@gnu.org>

	* configure.in: more HP stuff: fix the manual alloca code so that
	  gawk will compile and link on HP systems. See the comments.

Sun Apr 25 13:39:16 1999  Arnold D. Robbins  <arnold@gnu.org>

	* Makefile.in (gawk): add $(CFLAGS) to linking step.

	* custom.h: hacks for BeOS. Not documented in the manual right now.
	* configure.in: hacks for BeOS.  Check for HP-UX and define C_ALLOCA

	* BETA Release 3.0.41: Release tar file made.

Tue Nov  3 16:24:35 1998  Arnold D. Robbins  <arnold@gnu.org>

	* eval.c (r_get_lhs): Fix the cases for the special variables,
	  don't unref their current value if it's the same as the internal
	  copy; perhaps the current one is used in a concatenation or some
	  other expression somewhere higher up in the call chain.  Ouch.
	  See test/getnr2tm.awk.

Sun Nov  1 15:24:52 1998  Arnold D. Robbins  <arnold@gnu.org>

	* builtin.c (format_tree): improve handling of zero-fill
	  when a precision is present. See test/zeroflag.awk.

Wed Oct 28 20:40:17 1998  Arnold D. Robbins  <arnold@gnu.org>

	* eval.c (r_tree_eval): Case for Node_concat. Get lengths
	  separately, in case one expression has a side effect that
	  that changes another. Ugly, but it keeps gawk from core
	  dumping. See test/nasty.awk.

Sun Oct 18 21:27:24 1998  Arnold D. Robbins  <arnold@gnu.org>

	* awk.y (append_right): bug fix, if `list' or `new' are NULL,
	  return `list', so that things don't break too badly.
	* regex.c (re_compile_fastmap): remove unused variable `num_regs'.

Thu Oct  8 19:36:57 1998  Arnold D. Robbins  <arnold@gnu.org>

	* BETA Release 3.0.40: Release tar file made.

Mon Jul 27 10:14:33 1998  Arnold D. Robbins  <arnold@gnu.org>

	* node.c (parse_escape): Remove assignment with side effects
	  from ISXDIGIT test. Thanks to "Mihai T. LAZARESCU"
	  <mihai@ccmserv.polito.it> for pointing this out.

Mon Apr 27 11:31:32 1998  Arnold D. Robbins  <arnold@gnu.org>

	* main.c (usage): fix the email address for the bug list.
	  (copyleft): update the copyright year.

Mon Mar 23 21:22:32 1998  Arnold D. Robbins  <arnold@gnu.org>

	* eval.c (r_get_lhs): make sure that values of type
	  Node_param_list don't have the FUNC flag set. This means
	  we don't allow the use of a function name as a variable or
	  array from within the function.

Sun Mar 22 19:12:32 1998  Paul Eggert  <eggert@twinsun.com>

	* aclocal.m4 (GAWK_AC_LARGE_FILES): new macro that checks for
	  large file support, and updates CPPFLAGS, LDFLAGS, LIBS as
	  needed.
	* configure.in: call GAWK_AC_LARGE_FILES.
	* Makefile.in (CPPFLAGS, LDFLAGS): Let autoconf configure.
	(COMPFLAGS): Add $(CPPFLAGS).

Mon Mar 16 14:06:41 1998  Arnold D. Robbins  <arnold@gnu.org>

	* field.c (using_FIELDWIDTHS): new macro.
	  (using_fieldwidths): use new macro.
	  (do_split): in case for FS_DFLT, also check that
	  we're not using FIELDWIDTHS. Otherwise, split() would use
	  FIELDWIDTHS, not current value of FS. Oops.

Sun Nov 16 20:08:59 1997  Arnold D. Robbins  <arnold@gnu.org>

	* builtin.c (sub_common): fix for count of matches in gsub
	  from Geert.Debyser@esat.kuleuven.ac.be.

Wed Oct 15 03:38:12 1997  Arnold D. Robbins  <arnold@gnu.org>

	* field.c (set_FS): Use `sc_parsefield' if the value of FS is not
	  alphabetic OR if not ignoring case. Bug fix if IGNORECASE
	  is true and FS happens to be '^'. Sheesh, talk about obscure.
	  (rebuild_record): Add more smarts to the code that sets up the
	  fields. Thanks to Alan J. Broder (ajb@dtmr.com).

Sun Oct  5 11:56:52 1997  Arnold D. Robbins  <arnold@gnu.org>

	* configure.in: if ISC add -D_SYSV3 to CFLAGS, per email from
	  Mario Vanoni (vanonim@dial.eunet.ch).

Fri Sep 26 00:57:49 1997  Arnold D. Robbins  <arnold@gnu.org>

	* awk.y (append_right): return if either list is NULL. Prevents
	  syntax errors from causing core dumps.

Wed Sep 17 15:34:15 1997  Arnold D. Robbins  <arnold@gnu.org>

	* field.c (rebuild_record): set things up so that all fields point
	  into the new record and release any changed fields without
	  causing memory leaks.  Avoids problems when fields are extended
	  with the value of $0 or other fields and then $0 is assigned to.

Mon Sep 15 16:12:55 1997  Arnold D. Robbins  <arnold@gnu.org>

	* builtin.c (do_print): when testing for NUMBER, make sure
	  it's not a string too. Thanks to Michael Brennan for
	  clarifying the semantics.

Sun Sep 14 19:55:12 1997  Arnold D. Robbins  <arnold@gnu.org>

	* node.c (format_val): always format values ourselves: avoids
	  problems if OFMT is bizarre, like %s.

Sun Sep 14 00:08:53 1997  Arnold D. Robbins  <arnold@gnu.org>

	* io.c (get_a_record): replace all occurrences of the test
	  `grRS == FALSE' with `RS_is_null' which makes ` RS = "\0" '
	  actually work, is clearer code, and actually makes use of
	  the `RS_is_null' variable!

Sun Aug 17 07:15:12 1997  Arnold D. Robbins  <arnold@gnu.org>

	* field.c (set_FS): Change logic to always set parse_field, even
	  if FS hasn't changed. Thanks to Igor Sheyn for catching this.

Wed Aug  6 21:04:37 1997  Arnold D. Robbins  <arnold@gnu.org>

	* io.c (VMS et al gawk_popen): use pclose, not fclose, if
	  iop_alloc fails.

Wed Jul 30 19:53:52 1997  Arnold D. Robbins  <arnold@gnu.org>

	* awk.y [variable]: fix case for subscript if $3 == NULL.

Sun Jul 27 22:47:30 1997  Arnold D. Robbins  <arnold@gnu.org>

	* awk.y (get_src_buf): don't close file if it's stdin.

	* io.c (#if VMS: vmsrtl_fileno): new routine.
	  (#if VMS: fileno): new macro substituted for stdio one.

Thu Jul 17 20:05:59 1997  Arnold D. Robbins  <arnold@gnu.org>

	* builtin.c (do_print): When OFMT != CONVFMT, create a new
	  temporary node with just the numeric value valid and format it,
	  and use that for printing. Avoids memory corruption.

Wed Jul 16 10:01:16 1997  Arnold D. Robbins  <arnold@gnu.org>

	* regex.c: When SYNTAX_TABLE is defined, but not emacs, then
	  CHAR_SET_SIZE is not defined, though used in regcomp.  It should
	  be taken out of #ifdef SYNTAX_TABLE. Fix from bug group, from
	  Akim Demaille, demaille@inf.enst.fr.
	* awk.h (isnondecimal): make test a little smarter.
	  builtin.c (nondec2awknum): add bailout for decimal numbers, e.g.
	  `00.1'. Fix from Larry Schwimmer <rosebud@cyclone.Stanford.EDU>.

Thu Jun 19 19:00:40 1997  Arnold D. Robbins  <arnold@gnu.org>

	* eval.c (interpret): case Node_K_next, Node_K_nextfile: fatal
	  error if called from BEGIN or END.
	  (Fixed completely Mon May  3 13:31:42 1999.)

Mon Jun  9 22:40:04 1997  Arnold D. Robbins  <arnold@gnu.org>

	* builtin.c (nondec2awknum): Allow `f' and `F' in hexadecimal numbers.
	  Gotta get more sleep...
	* array.c (assoc_lookup): Fix from Tom Karzes (karzes@equator.com)
	  for memory leak when forcing type to Node_var_array.

Thu May 15 12:49:08 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Release 3.0.3: Release tar file made.

Wed May 14 08:06:08 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (do_close): add lint warning if closing something that
	  isn't open.

Tue May 13 12:14:12 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* random.c, builtin.c: remove __GLIBC__ tests, since it breaks
	  `make test'. I prefer consistency across platforms.
	* Makefile.in (gawk): undid April 25 changes and added comment.
	  Putting COMPLAGS in breaks with -g on VMS POSIX.

Sun May 11 14:48:04 1997  Darrell Hankerson  <hankedr@mail.auburn.edu>

	* io.c [MSC_VER]: add cases for WIN32.
	* regex.c [MSC_VER]: add cases for WIN32.

Sun May 11 07:04:01 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_print): in the loop that evaluates each expression
	  to be printed, do a dupnode to avoid bizarre output. Thanks to
	  Michal for finding this problem.
	* awk.y (yylex): fix scanning of hexadecimal constants.

Wed May  7 15:09:25 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (get_a_record): fix casetable indexing with cast to int.
	  Keeps Michal happy.

Tue May  6 16:40:19 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (func_call): removed unneeded variables.

Mon May  5 21:17:37 1997  Pat Rankin  <rankin@eql.caltech.edu>

	* missing/strftime.c [case 'v', VMS_EXT]: for VMS date format, two
	  digit day of month should not be zero padded on the 1st through
	  the 9th.

Mon May  5 06:33:47 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* regex.h, regex.c: merge with current GLIBC version.

Mon May  5 06:33:47 1997  Pat Rankin  <rankin@eql.caltech.edu>

	* io.c (nextfile): move the check for null return from iop_open
	  in the normal case and add one for the "no args" case.

Fri Apr 25 16:52:33 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* array.c (grow_table): add a bunch more large primes so arrays
	  can get really big. Thanks to christos@deshaw.com.
	* all files: remove ifdef'ed out code and update copyrights.
	* Makefile.in (gawk): add $(COMPFLAGS) to command line.
	* eval.c (flags2str): added case for FIELD.

Thu Apr 24 22:39:23 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* COPYING: changed to current official version from FSF.
	* regex.c: merge with GLIBC version.
	* awk.h [_GNU_SOURCE]: bracket definition inside ifdef.
	  (NODE.source_line): move name member out of `x' union and
	  into `nodep'; avoids problems doing diagnostics.
	  (nondec2num): put decl into #if BITOPS || NONDECDATA
	* posix/gawkmisc.c, missing/system.c, missing/strtod.c,
	  missing/strerror.c: move to generic GPL statement at top.
	* builtin.c (nondec2num): put into #if BITOPS || NONDECDATA

Wed Apr 23 22:14:14 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* dfa.c: misc changes for really pedantic SGI compilers.
	* builtin.c: bracket defs of random() etc for GLIBC.
	* random.c: bracket whole file for GLIBC.
	* configure.in: extra goop for GETPGRP test for VMS POSIX.
	* custom.h [VMS]: remove hard definition of GETPGRP_VOID.

Fri Apr 18 07:55:47 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* BETA Release 3.0.34: Release tar file made.

Tue Apr 15 21:35:45 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
	* acconfig.h [NONDECDATA]: new macro.
	* awk.h: add decl of do_strtonum.
	* awk.y (tokentab): add entry for strtonum function.
	* builtin.c (do_strtonum): new function.

	  ifdef NONDECDATA.

Tue Apr 15 06:32:50 1997  Pat Rankin  <rankin@eql.caltech.edu>

	* missing/strftime.c (malloc, realloc, getenv, strchr): only
	  declare these when STDC_HEADERS is not defined.
	  <stdlib.h, string.h>: include these when STDC_HEADERS is defined.
	* awk.h (freenode, tree_eval, m_tree_eval): reorganize definitions.
	* alloca.c (malloc): if malloc is already defined as a macro,
	  presumeably by config.h, don't define or declare it.

Wed Apr  9 22:45:27 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in [COMPFLAGS]: per suggestion from Karl Berry, put
	  $(CFLAGS) last.

Tue Apr  8 23:54:46 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (interpret): For Node_K_break and Node_K_continue, if
	  treating them like `next', also check the function call stack
	  and pop it if necessary.

Mon Apr  7 18:22:37 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.h: Add decls of new routines do_compl() and set_loc().
	* awk.y (tokentab): add entry for "compl" function.
	* builtin.c (do_compl): new function to do ones complement.
	  (do_substr): rationalized yet again, now notices negative start
	  and length parameters.
	* eval.c (push_args): fix if call_list gets realloc'ed in the
	  middle of things. Avoids crash for deeply nested function calls.
	* main.c (catch_sig): add call to set_loc().
	* msg.c (set_loc, srcfile, srcline): new function and private
	  variables to help out in tracing down source of error messages.

Fri Mar 28 08:42:27 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (iop_alloc, iop_close): Undo changes of Feb 11, apparently
	  other cleanups in io.c made mmap stuff start working again.
	  BAH! It's a mess, the test suite still fails. I'm leaving the
	  mmap stuff undefined for now. It'll probably get ripped out in 3.1.

Thu Mar 27 08:48:57 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* custom.h [_SEQUENT_]: undef HAVE_MMAP.

Wed Mar 26 09:08:16 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (iop_alloc): fix definition to make it static.

Mon Mar 24 23:09:07 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* field.c (init_fields, etc..): more clean up use of Null_field
	  and the various flags.
	* node.c (unref): if a field, free the node itself. Fixes
	  memory leak problems.

Sun Mar 23 22:51:09 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.h [FIELD]: new flag for node->flags field.
	* builtin.c (sub_common): if FIELD is set, dup the string.
	* field.c (init_fields): set up a new Null_field global var.
	  (init_fields, set_field, set_record) use the FIELD flag.
	  (getfield): use Null_field instead of private variable.
	* io.c (wait_any): comment out calls to pclose and iop_close,
	  caused weird race conditions. See test/pipeio1.awk. Thanks
	  to Darrell Hankerson for tracing this one down.

Tue Mar 18 20:57:18 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* dfa.c (inboth): free templist; plugs memory leak.
	* field.c (init_fields, grow_fields_arr, set_field, rebuild_record,
	  set_record): remove PERM flag from entries in fields_arr[]. Fixes
	  nasty memory leak.

Tue Mar 18 06:33:00 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.y (dup_parms): robustified against parameter errors.

Sun Mar 16 21:31:40 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
	* acconfig.h [BITOPS]: new macro. If set, do octal & hex and bit ops.
	* awk.h [isnondecimal]: new macro, and decl of new functions.
	* awk.y (yylex): add recognition of octal and hex constants.
	* builtin.c (do_and, do_or, do_xor, do_lshift, do_rshift): new
	  functions that do bit operations.
	  (nondec2awknum): new function to convert octal or hex to double.
	* configure.in: Add AC_ARG_ENABLE for bit operations.
	* node.c (r_force_number): add octal and hex conversion.

Sun Mar 16 21:28:56 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.h [IOP_NOFREE_OBJ]: new macro.
	* io.c (iop_open, iop_alloc): add new third parameter, which is
	  either NULL, meaning allocate a new IOP, or the address of one
	  already allocated.  Have a static one in the `nextfile'
	  routine, and use the IOP_NOFREE_OBJ flag for it.  All of this
	  keeps us from reading freed memory. The `swaplns' test fails
	  otherwise.
	  (iop_close): if IOP_NOFREE_OBJ is set, don't free the IOBUF.

Wed Feb 26 06:21:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (in_function, pop_fcall_stack, pop_fcall, push_args):
	  new functions. These manage "frames" of awk function call arguments.
	  The problem is that a `next' or a `nextfile' from a function
	  leaks memory. These changes allow us to free up that memory.
	  (interpret): for Node_K_next and Node_K_nextfile, check if in
	  a function call and free all function call frames.

Fri Feb 21 06:23:19 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Misc changes from Katsuyuki Okabe <HGC02147@niftyserve.or.jp>:
	* builtin.c (do_substr): change a %d to %ld in warning message.
	* eval.c (op_assign): fix format string for warning about %=.

Wed Feb 19 23:29:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* main.c (main): add do_intervals to condition that causes
	  resetup() to be called again. Makes the --re-interval option
	  actually work. What a concept.

Fri Feb 14 09:47:31 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c [#include "awk.h"]: undef HAVE_MMAP to just use the old code.
	  Something is causing a file descriptor leak, and this is getting to
	  be just too much hair. I reserve the right to rip out the mmap
	  code entirely at a future date.

Tue Feb 11 06:28:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (iop_alloc): for an mmap'ed file, close the file descriptor,
	  and then touch each page to get a private copy. Fixes nasty case
	  of truncating our input file.
	  (iop_close): don't call close on mmap'ed file.

Wed Feb  5 17:59:04 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (interpret): For Node_K_delete, just call do_delete; let
	  it handle the case of `delete array'.
	* array.c (do_delete): Changed to handle case of `delete array',
	  and made smarter if the array is actually an uninitialized
	  parameter.

Sun Jan 26 22:58:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* getopt.h, getopt.c, getopt1.c: replaced with new versions from
	  GLIBC 2.

Sun Jan 19 23:37:03 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (nodetype2str): not static, for debugging.
	  (flags2str) new function: for debugging.
	* field.c (get_field): add new var that is like Nnull_string but
	  does not have numeric attributes, so that new fields are strings.
	  (set_record): turn off PERM flag before unrefing fields and field 0.
	* array.c (in_array): always evaluate subscript, could have
	  side effects.
	* builtin.c (do_strftime): way increase size of buffer to make sure
	  we don't have overflow problem. Keeps Paul Eggert happy.
	* custom.h [__amigaos__]: define fork to vfork. From Fred Fish.
	* dfa.c: move include of config.h to top, for RSXNT. From Kai
	  Uwe Rommel.
	  (ISALPHA, etc): change from Jacob Engelbrecht (jaen@novo.dk)
	  to better handle non-ascii environments.
	* gawkmisc.c: remove amigados case, posix should now work fine.
	* amiga/*: nuked per previous entry.
	* Makefile.in: removed all references to amiga
	* io.c [HAVE_SYS_PARAM_H]: Add #undef RE_DUP_MAX to avoid
	  spurious conflict with regex.h.
	  (flush_io): remove amiga ifdefs, not needed anymore.
	  (spec_setup): set getrec field for special files. Fix from
	  Mark Gray (markgray@pdt.net).
	* node.c (more_nodes): fix to get the last entry in the array.

Wed Jan  8 17:42:37 1997  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* io.c (mmap_get_record): Fix return value if file ends without
	  record separator.

Fri Jan  3 19:57:16 1997  Pat Rankin  <rankin@eql.caltech.edu>

	* awk.y (get_src_buf):  Test for an empty source file by detecting
	  an initial read of 0 bytes rather than by relying on info from
	  stat().

Wed Dec 25 11:25:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Release 3.0.2: Release tar file made.

Wed Dec 25 11:17:32 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (install, uninstall): use $(srcdir)/patchlevel.h.
	  Thanks to Richard Levitte, LeViMS@stacken.kth.se.
	  (install): remove chmod command; let $(INSTALL_PROGRAM) use -m.

Mon Dec 23 20:36:59 1996  Pat Rankin  <rankin@eql.caltech.edu>

	* custom.h (#if VMS_POSIX):  Define GETPGRP_VOID.

Fri Dec 20 08:59:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* getopt.c, getopt1.c: comment out the `#if defined (_LIBC) ||
	  !defined (__GNU_LIBRARY__)' and `#endif' to force use of this
	  getopt, even on systems like linux.  This will be handled
	  better in 3.1 / glibc 2.

Thu Dec 19 22:52:39 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.y (yylex): In several places, after yyerror(), add call to
	  exit(). Otherwise, infinite messages. This should probably
	  be handled better.

Wed Dec 18 22:42:10 1996  Darrel Hankerson  <hankedr@mail.auburn.edu>

	* getopt.c (_getopt_internal): if 'W' and ';', if optind == argc,
	  return c, don't fall through.

Wed Dec 18 10:09:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* configure.in [AC_PREREQ]: Update to 2.12 in order to switch to
	  autoconf 2.12. Lots of other files will be rebuilt automatically.
	  [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.
	* aclocal.m4 [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.

Tue Dec 17 22:23:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_strftime): fix case if format string is "".
	  Also fix it if format is not "" but result of strftime is "".
	  See comments in code.

Tue Dec 10 23:09:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Release 3.0.1: Release tar file made.

Tue Dec 10 22:39:41 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (dist): add dependency on `info'. Remove line that
	  does makeinfo.
	  (install): use $(LN) not $(LN_S) to link gawk gawk-version.

Sun Dec  8 07:53:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (gawk): took COMPFLAGS out of link line for help
	  on VMS posix. Shouldn't (I hope) affect anything else.

Thu Nov 28 11:52:24 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* configure.in (AC_PROG_INSTALL): Set INSTALL to install-sh.

Tue Nov 26 22:42:00 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* PORTS: Updated list of systems.
	* Makefile.in (install): Fix some typos and add some improvements
	  for Ultrix.

Sun Nov 24 22:16:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_printf): if no args, fatal error. Return silently
	  if --traditional.

Thu Nov  7 20:54:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (inrec): make sure EOF hasn't already happened before
	  trying to read; prevents accessing freed buffer. Thanks to
	  Michal Jaegermann.
	* Makefile.in [AWKSRC]: add random.h.
	  random.h: new file, redefines names of the `random' functions.
	  random.c, builtin.c: add include of random.h.

Thu Nov  7 09:06:21 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.y (snode): undo 4 Oct change, put do_split code back.
	  field.c (do_split): restore old code; add test for CONST, so
	  that re_parse_field is used if third arg to split is a regexp
	  constant.

Mon Nov  4 12:57:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* main.c (main): Research -m[fr] options don't need literal '='
	  characters. Brian's documentation was confusing.  Fixed, not
	  that anyone actually uses these options with gawk.

Sun Nov  3 11:23:21 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* field.c (def_parse_field): add \n to list of acceptable white space.
	  (posix_def_parse_field): new routine, just like def_parse_field(),
	  but only allows space and tab as separators.
	  (do_split, set_FS): make appropriate choice between the two
	  *def_parse_field() routines.

Fri Oct 25 10:13:06 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* configure.in: remove test for random.

	* builtin.c (do_tolower, do_toupper): Add `unsigned char *' casts.

Tue Oct 22 21:27:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c [GAWK_RANDOM_MAX]: Try to make definition a bit
	  smarter; don't use RAND_MAX if it's equal to SHRT_MAX, blows
	  things up.

Tue Oct 22 08:49:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* main.c (copyleft): update copyright date to 1996.
	  too many files to list: update copyright date to 1996.

Sun Oct 20 12:21:09 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.y, dfa.c, eval.c, io.c, re.c: added various FIXME comments.

Sat Oct 19 22:06:42 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (nodetype2str): make static, add prototype.

Fri Oct 18 09:00:49 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* regex.h [RE_SYNTAX_AWK]: add RE_CONTEXT_INDEP_ANCHORS.

Thu Oct 17 22:32:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* aclocal.m4 [AM_SANITY_CHECK_CC]: added.
	* configure.in: use it.

Thu Oct 17 21:43:25 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* configure.in: add checks for locale.h and setlocale().
	  awk.h: include locale.h and define out setlocale() if not available.
	  main.c (main): call setlocale().
	  builtin.c (do_tolower, do_toupper): use unsigned char pointers,
	  to get other charsets right in different locales.

Wed Oct 16 21:32:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (format_tree): Change initial buffer size to 512
	  and use a constant. Allows large values of %f per bug report
	  from sheyn@cs.bu.edu.

Wed Oct 16 21:22:08 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in [MISC]: removed TAGS and tags
	  (local-distclean): added TAGS and tags
	  (maintainer-clean): removed TAGS and tags

Wed Oct 16 12:28:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* main.c (version): Add call to copyleft(), per new standards.
	  version.c: Fix text of version string to match new standards.

Sun Oct  6 22:19:45 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* regex.c: updated to Emacs 19.34b base.

Sun Oct  6 21:57:34 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* re.c (make_regexp): fixed to handle \8 and \9 in the middle
	  of a regexp.

Fri Oct  4 10:26:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.y (snode): remove case for do_split; always making the
	  third arg a Node_regex is wrong.
	  field.c (do_split): rationalized to distinguish `/ /' from `" "'.
	  Generally fixed up.
	* node.c (parse_escape): Allow single digit \x escapes.

1996-10-02  Paul Eggert  <eggert@twinsun.com>

	* builtin.c (format_tree):
	Fix bug in %d and %i format: NaNs, and values
	in the range LONG_MAX+1 .. ULONG_MAX, were mishandled.
	Don't assume that double values <= -1 are converted to unsigned
	long in the expected way; the C Standard doesn't guarantee this.

1996-10-02  Paul Eggert  <eggert@twinsun.com>

	* awk.h (INT_MAX): Remove unused symbol.

Mon Sep 30 22:19:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* getopt.c (_getopt_internal): If 'W' is in the optstring followed
	  by a ';' then search through the long opts table. This makes
	  `-W foo=bar' same as `--foo=bar'.
	* main.c (main): 'W' now prints an error message.
	  (gawk_option): deleted the routine.

Sun Sep 29 23:04:54 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (sub_common): fix several bugs with gsub when
	  matching null strings. See test/gsubtest.awk.

Fri Sep 20 17:35:54 1996  Pat Rankin  <rankin@eql.caltech.edu>

	* alloca.c (NULL): don't define if <config.h> has already done so.

Fri Sep 20 11:54:31 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_print): evaluate all the expressions first and
	  then print them. Avoids surprising behavior. See test/prtoeval.awk
	  for an example.

Tue Sep 10 06:21:40 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.h [FUNC]: new flag, marks a Node_parameter_list as really
	  being the function name; allows more checking in awk.y.
	* awk.y (isassignable): now takes a NODE * instead of a type, to
	  check if a function parameter is marked FUNC, then it's the function
	  name, which is not assignable. Fix call from snode().
	  (function_prologue): mark function name as FUNC.
	  (yyerror): don't call exit() anymore; gawk will now report
	  all syntax errors.

Sun Sep  1 19:36:30 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* field.c (rebuild_record): after building new field 0, go through
	  all old fields, and if they used to point into the old one,
	  have them point into the new one.  Then turn off PERM flag before
	  unref-ing field 0.

Wed Aug 28 19:13:34 1996  Arnold D. Robbins  <arnold@math.utah.edu>

	* eval.c (set_IGNORECASE): Correctly parenthesize bit operations
	  in test and fix logic for string value.

Wed Aug 28 22:06:33 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* main.c (usage): add email addresses for bug reporting, per
	  change in GNU Coding Standards from RMS.

Sun Aug 11 23:13:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (install): correct use of $(INSTALL_PROGRAM).

Thu Aug  8 23:29:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* parse.y (isassignable): new function, checks in type can
	  be assigned to.
	  (snode): changed checking for 3rd arg of gsub to be more
	  general, supersedes earlier change.

Thu Aug  8 13:58:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* parse.y (snode): If third arg to sub or gsub is builtin
	  function, complain, since can't substitute into result.
	* eval.c (r_get_lhs): diagnose Node_builtin as an error, instead
	  of falling through into default case and using cant_happen().

Thu Aug  1 07:13:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* regex.h [RE_DEBUG]: new macro.
	  [RE_SYNTAX_GNU_AWK]: add RE_DEBUG.
	  [RE_SYNTAX_POSIX_AWK]: add RE_INTERVALS.
	* regex.c (re_set_syntax): add #ifdef DEBUG code to turn on `debug'
	  flag if RE_DEBUG set, and turn off debug if not set and debug
	  was on.
	* main.c (main): remove `do_intervals = TRUE' from `if (do_posix)',
	  it's now handled in the definition of RE_SYNTAX_POSIX_AWK.

Mon Jul 29 17:49:07 1996  Pat Rankin  <rankin@eql.caltech.edu>

	* io.c (O_ACCMODE): define it if <fcntl.h> doesn't.

Mon Jul 29 12:02:48 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (set_IGNORECASE): made somewhat smarter. gawk -v IGNORECASE=0
	  was acting the same as -v IGNORECASE=1. Thanks to Darrell Hankerson
	  for the bug report.

Fri Jul 26 12:04:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.h (format_val): add declaration of new routine.
	* node.c (format_val): new routine, abstracts old guts of
	  r_forcestring; accepts format string and index as additional params.
	  (r_force_string): changed to call format_val.
	* builtin.c (do_print):  don't tree_eval the tree twice in case
	  OFMTidx != CONVFMTidx; doing so could cause side effects
	  (from bug report by Tobias Rettstadt, xassp@ipds.uni-kiel.de).
	  Instead, call format_val.

Mon Jul 22 21:59:15 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (iop_close): change check for "is $0 in the input buffer"
	  to use `< (iop->buf + iop->secsiz + iop->size)' instead of
	  `< iop->end'. The latter is bogus if EOF has been hit on the
	  file.  Fix from Darrel Hankerson based on bug report by
	  Charles Howes (howes@grid.direct.ca).  See test/eofsplit.awk.

Thu Jul 18 19:43:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (sub_common): backed out change of Feb 14 in favor of:
	  (do_gensub): Changed to use make_string and then to |= TEMP
	  flag, based on bug report and patch from Katsuyuki Okabe,
	  hgc02147@niftyserve.or.jp.

Thu Jul 18 19:23:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* custom.h: added ifdef for QNX, based on bug report from
	  Michael Hunter, mphunter@qnx.com.

Mon Jul 15 09:31:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (redirect): When finding the rp pointer, if it's not
	  NULL, set str = rp->value. This gets the '\0' terminated
	  version. Motivated by bug report from John Hawkinson
	  (jhawk@bbnplanet.com).

Sun Jul 14 18:40:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* configure.in: added call to AC_CHECK_LIB(m, fmod), since
	  apparently some systems have fmod in the math library.
	  Portability: the Holy Grail.  Sigh.

Sun Jul 14 18:08:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.h: add Jim Meyerings ISASCII etc hacks for ctype macros.
	* builtin.c (do_toupper, do_tolower, sub_common): changed to use
	  upper-case versions of ctype macros.
	* main.c (main): ditto.
	* node.c (r_force_number, parse_escape): ditto.

Sun Jul 14 06:34:18 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* field.c (set_record): made it always do the PERM flag.
	  Fixes cases where $0 is assigned to, e.g. by gsub, keeps
	  the fields valid.
	  (get_field): removed the call to reset_record in
	  case where ! field0_valid. We want to leave the fields alone
	  if they've been changed.

Thu Jul 11 23:04:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (devopen): change tests of (flag & O_fooONLY) to
	  (flag & O_ACCMODE) == O_fooONLY. Per (long standing) bug
	  report from Chapman Flack.
	  (close_redir): change final conditional to just (status != 0)
	  so that ERRNO always set; the warning had its own `if (do_lint)'
	  anyway.
	* eval.c (do_split): force type of array to be Node_var_array
	  instead of Node_var.  Per (long standing) bug report from
	  Chapman Flack.

Thu Jul 11 22:17:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (install): added symlink of gawk to awk if
	  no awk in $(bindir).
	  (LN_S): new variable for symlinking.
	  (uninstall): remove awk if it's the same gawk.
	* Configure.in: Added call to AC_PROG_LN_S for Makefile.in.

Sun Jul  7 15:47:13 1996  Arnold D. Robbins  <arnold@infographix.com>

	* main.c (main): made `--posix' turn on interval expressions.
	  Gawk now matches its documentation. (What a concept!)

Wed Jul  3 15:02:48 1996  Arnold D. Robbins  <arnold@infographix.com>

	* regex.h, regex.c: upgraded to changes from Emacs 19.31.

Fri May 17 08:46:07 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (get_a_record): added `continued' flag. Fix from
	  Darrell Hankerson for when RS = "\n|something".

Wed May 15 02:34:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (awklib/all): now depends on gawk, fixes problem
	  with parallel make.

Tue May 14 15:02:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (format_tree): fix handling of '*' to deal with
	  negative value for fieldwidth -- make positive and turn on
	  left justify. Per bug report from Michael Brennan.

Sun May 12 20:42:06 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* eval.c (r_get_lhs): case Node_subscript. Check if array name
	  is actually a function, fatal error if so.

Sun May  5 10:11:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (redirect): call flush_io() before creating a new output pipe,
	  per bug report from Brian Kernighan (bwk@research.bell-labs.com).

Fri Mar 15 06:38:33 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (install): use $(INSTALL_PROGRAM), not $(INSTALL).
	  (local-distclean): add `*~' to list of files to be removed.
	  (CFLAGS): now contains just @CFLAGS@.
	  (COMPFLAGS): replaces use of CFLAGS, has CFLAGS plus all the
	  other stuff.

Wed Mar 13 14:19:38 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (mmap_get_record): fixed to not place sentinel at end
	  of mmap'ed object. Won't work if file is exact multiple of
	  disk block size. See comments in code for more info.
	  Thanks to Rick Adams (rick@uunet.uu.net) for help in testing.

Sun Mar 10 22:50:23 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* io.c (do_close): notice if we were called as `close(FILENAME)'
	  and arrange to close the current input file. This turns out
	  to be easy to do, just call `nextfile(TRUE)'. Based on bug report
	  from Pascal A. Dupuis, <dupuis@lei.ucl.ac.be>.

Thu Mar  7 08:08:51 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* field.c (init_fields, grow_fields, set_field, rebuild_record):
	  Nuke the `nodes' array everywhere.  Anytime a field is unref'ed,
	  allocate a new node that is a copy of Nnull_string. This avoids
	  subtle memory management problems when doing a lot of assignment
	  to fields, and tweaking of NF. Make sure that fields_arr[0] always
	  has a type of Node_val!
	* field.c (set_NF): If NF is decremented, clear fields between
	  NF and parse_high_water, otherwise if NF incremented, clear
	  fields between parse_high_water and NF.
	* eval.c (nodetype2str): new function, used for diagnostics.
	  eval.c (interpret): use nodetype2str when finding invalid node.

Mon Mar  4 09:02:28 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_toupper, do_tolower): use isascii along with
	  isupper/islower before changing case, in case characters have
	  the high bit set. This is a hack.

Mon Feb 26 22:24:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (sub_common): if no match, and called from gensub,
	  don't free the temporary string, since the tmp_number then
	  writes over it.

Sun Feb 25 23:13:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (format_tree): fixed %c to treat user input as
	  numeric also by adding test for MAYBE_NUM.

Tue Feb 20 12:25:50 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* configure.in: Added AC_FUNC_MMAP call and add madvise to
	  list of functions to look for.
	* awk.h [IOP_ISMAPPED]: new flag value for mmap support and new
	  `getrec' structure member in struct iobuf.
	* io.c (iop_alloc, iop_close): changed to map/unmap input file
	  into memory if possible.
	  (mmap_get_record): new function to actually retrieve the
	  record from mmaped file.

Thu Feb  1 08:56:46 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_substr): fixed lint message to use indx+1 when
	  start position is past end of string.

Sun Jan 28 07:00:56 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_substr): rationalized handling of missing length
	  argument, as well as various accompanying lint warnings. Previous
	  code was slightly bogus. Talk about your Day 1 bugs.

Thu Jan 25 14:09:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* builtin.c (do_substr): if length exceeds length of actual
	  string, do computation of needed substring length *after*
	  the lint warning.

Wed Jan 24 10:06:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* Makefile.in (gawk): Add $(CFLAGS) to link line.
	  (Makefile): target depends on the Makefile.in files.
	  (OTHERS): Added TAGS and tags to the distribution.
	  (local-distclean): New rule.
	  (distclean): Use it.
	  (maintainer-clean): Don't `make distclean' before running submakes,
	  since that removes makefiles needed for the submakes.
	* builtin.c (do_strftime): Remove hard coded limit on length of result.
	  Based on code from Paul Eggert (eggert@twinsun.com).

Mon Jan 22 13:16:37 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* main.c (usage): takes new fp parameter which is either
	  stdout for `--help' (per the GNU Coding Standards) or stderr
	  if an error occurs. Fix all calls.
	  (version): prints to stdout per the coding stds.
	  (copyleft): prints to stdout now, not stderr, and exits.

Fri Jan 19 08:10:29 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* regex.h [RE_GNU_AWK]: added RE_CONTEXT_INDEP_OPS to set of
	  bits we turn off for regular operation. Breaks things like
	  /^+[0-9]+/ to match a literal `+' at the beginning of, say,
	  a phone number.

Wed Jan 10 23:19:36 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* 3.0.0 polished up and release tar file made.

Wed Dec 27 11:46:16 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* 2.94.0 released to porting group (no, I haven't been good
	  about this file; I'll do better once 3.0 is released).

Mon Aug 28 23:04:30 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* awk.h updated for NeXT - bracket TRUE/FALSE
	* io.c (get_a_record): removed shadowing of 'start' in
	* Makefile.in and doc/Makefile.in: fixed to use gawk.1 and gawk.texi,
	  instead of gawk.1.in and gawk.texi.in.

Mon Aug 25 11:04:30 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* 2.90.0 released to porting group.

Fri Aug 18 12:43:31 1995  Arnold D. Robbins  <arnold@puny.ssc.com>

	* ChangeLog created.
