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>

	Port the large-file code to AIX, HP-UX, and IRIX.
	Add cross-compilation support for large files.

	* config.guess, config.sub: New files.

	* configure.in (AC_CANONICAL_HOST):
	  Add; GAWK_AC_SYS_LARGEFILE needs this.
	  (GAWK_AC_SYS_LARGEFILE): Renamed from GAWK_AC_LARGE_FILES.

	* aclocal.m4 (GAWK_AC_SYS_LARGEFILE): Renamed from GAWK_AC_LARGE_FILES.
	  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.

	* BETA Release 3.0.45: Release tar file made.

Tue May 25 16:32:37 1999  Arnold D. Robbins  <arnold@gnu.org>

	* builtin.c (format_tree): more smarts for weird cases, such as
	  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
	  set want_assign = FALSE.  Fixes bizarre parsing problems in
	  function call lists, for example.
	* io.c (get_a_record): repair logic for single-leading-newline
	  case.

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

	* aclocal.m4 (GAWK_AC_AIX_TWEAK): new macro.
	* configure.in: call it
	* Makefile.in: (awklib/all): pass CFLAGS on to sub-make so
	  that password programs will get AIX magic defines. Avoids
	  having to tweak program code for those in doc/gawk.texi.

Mon May  3 16:56:23 1999  Arnold D. Robbins  <arnold@gnu.org>

	* array.c (do_delete): don't free_temp(subs) until after all
	  references to it are finished.

Mon May  3 13:41:16 1999  Arnold D. Robbins  <arnold@gnu.org>

	* BETA Release 3.0.44: Release tar file made.

Sun May  2 18:25:43 1999  Arnold D. Robbins  <arnold@gnu.org>

	* io.c (get_a_record): Do a really good job of stripping newlines
	  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.
	* configure.in: correctly do AC_FUNC_GETPRGP on HP systems too.

Tue Apr 13 20:21:00 1999  Arnold D. Robbins  <arnold@gnu.org>

	* BETA Release 3.0.43: Release tar file made.

Tue Apr 13 19:02:20 1999  Arnold D. Robbins  <arnold@gnu.org>

	  silence gcc warnings.
	* regex.c (regcomp,regexec,regfree): add ifdef for APPLE.

Thu Feb  4 10:38:02 1999  Arnold D. Robbins  <arnold@gnu.org>

	* 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
	  if not using gcc.  I wish they'd just fix bison already.

Sun Dec 20 16:57:38 1998  Arnold D. Robbins  <arnold@gnu.org>

	* BETA Release 3.0.42: Release tar file made.

Sun Nov 15 21:05:39 1998  Arnold D. Robbins  <arnold@gnu.org>

	* 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 lengthes
	  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.

	  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.

	* 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 functionto 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 thoe 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.
	* alocal.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>

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>

	* missing.c: remove HAVE_RANDOM test.
	* builtin.c: remove ifdef's for HAVE_RANDOM.
	  [GAWK_RAND_MAX]: use constant we know works with our 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.

	* 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>

	* 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 suprising 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 parrallel 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 diganostics.
	  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 accompagnying 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.
