569 * stackovf.c: Split setting up the trap handler and catching
570 signals, for better taking care of various configure outcomes.
571 * examples/stackovf.sh: Correct a typo.
572 Reported by Eric Backus, Jim Avera and Jim Meyering.
574 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
576 * ansi2knr.c: New version sent by its author, Peter Deutsch.
578 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
580 * Makefile.in: Modify so parallel make will not try making
581 lib/libm4.a twice simultaneously.
582 Reported by Jim Meyering.
584 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
586 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
587 error message, for when no code possibility exists. Even if this
588 line is completely #ifdef'ed out, it brings a syntax error.
589 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
591 * Makefile.in (install): Have install depend on all too, for lib
592 to be remade as needed.
594 * examples/stackovf.sh: Try ksh, bsh and bash for shells
595 providing ulimit, instead of using only ksh.
596 Reported by Jim Avera and Joseph E. Sacco.
598 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
600 * Makefile.in (check): Have it depend on all instead of m4. In
601 this way, a change in lib will be detected and processed.
603 * builtin.c (numeric_arg): Use strtol and verify the conversion,
604 instead of using sscanf which stops as soon as there is a
605 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
606 and divert(1xyzzy) were all accepted without any warning or error
608 * m4.h: Declare strtol as long if not including stdlib.h.
609 * configure.in: Check for limits.h, and replace strtol if missing.
610 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
611 * lib/strtol.c: New file, from elsewhere.
612 Reported by Andreas Schwab.
614 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
616 * macro.c (expand_macro): Cast value to (boolean) prior to
617 assigning it to traced.
618 Reported by Tom McConnell.
620 * Makefile.in (m4): Always make all in lib first.
621 Reported by Jim Meyering.
623 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
625 * stackovf.c: Isolated OS-dependent sections; Improved portability,
626 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
627 handlers), and a default error message if the fault address is not
628 available (when neither siginfo.h nor BSD sigcontext are supported).
629 * configure.in: Changes for stackovf.h: Check for sigcontext,
630 sigaction, sigstack, and define rlim_t as int if necessary.
631 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
632 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
633 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
635 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
637 * configure.in: Use AC_SET_MAKE.
638 * Makefile.in: Use @SET_MAKE@.
639 Reported by Jim Meyering.
641 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
642 Reported by Ian Taylor.
644 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
646 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
647 because siginfo.h is unrelated to standard headers, and siginfo.h
648 is already checked for.
649 Reported by Joseph E. Sacco.
651 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
653 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
656 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
658 * builtin.c (substitute): Use \& to represent this part of the
659 string which was matched by the whole regexp, instead of
660 representing the whole string. Any usage of \0 issues a warning
661 and acts like \&, it will disappear in some subsequent release.
663 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
665 * m4.c: Complete prototype for forwarded declaration of usage.
667 * input.c (init_macro_token): Correct own reference in error
668 message. Previous name get_macro_func was referred to instead.
669 (next_char): Correct own reference in error message. Previous
670 name advance_input was referred to instead.
672 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
673 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
674 and_term, not_term, logical_not_term, cmp_term, shift_term,
675 add_term, mult_term, exp_term, unary_term, simple_term): Add
676 prototype to forwarded declarations. Declare parameter v1 as
677 eval_t * instead of int *. Same for local variable v2 in dyadic
678 functions. Same for result in exp_term.
679 * builtin.c (m4_eval): Declare value as eval_t instead of int.
680 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
681 unsigned_eval_t instead of unsigned int. Change casts accordingly.
682 (shipout_int): Cast first argument of ntoa to eval_t.
683 Reported by Thorsten Ohl.
685 * macro.c: Complete the prototypes of forwarded expand_macro and
687 Reported by Thorsten Ohl.
689 * m4.h: Define voidstar as void * or char * depending on __STDC__.
690 The Ultrix 3.1 compiler cannot do much with void pointers.
692 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
693 * m4.c (xfree): Replace void * by voidstar.
694 Reported by Tom McConnell.
696 * ansi2knr.1: New, from elsewhere.
697 * Makefile.in (DISTFILES): Distribute ansi2knr.1
699 * Makefile.in (stamp-h.in): Avoid running ./config.status if
700 stamp-h does not exist yet. This avoids running it a second time
701 just after the initial ./configure.
702 Reported by David MacKenzie and Tom McConnell.
704 * m4.h: Replace the enum debug_info declaration with a series of
705 #define's. The Ultrix 3.1 compiler would otherwise need casting
706 (int) to most references, when used in expressions.
707 Reported by Tom McConnell.
709 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
711 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
712 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
713 calls the compiler. Previously, FP_PROTOTYPES was only calling
714 the preprocessor; by not being subject to CFLAGS, this was
715 discouraging those flags asking for ANSI compilation.
716 * acconfig.h: Document HAVE_PROTOTYPES.
717 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
718 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
719 Reported by Eric Backus.
721 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
722 from the environment. Default CFLAGS to -g if not set.
723 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
724 * lib/Makefile.in: Have CFLAGS substituted from configure.
725 Reported by Eric Backus and Tom McConnell.
727 * configure.in: m4_undefine changeword before using AC_ENABLE.
729 * m4.h: Declare prototypes for error (for ANSI compilers only),
730 prefix_all_builtins and reference_error.
731 Reported by Tom McConnell.
733 * input.c (set_word_regexp): Do not try to initialize the array
734 test from a string, this does not work with non-ANSI compilers.
735 Reported by Eric Backus.
737 * Makefile.in (dist): Clean examples/ before saving it.
738 (distclean-local): Also remove stamp-h.
739 Reported by Eric Backus.
741 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
743 Reported by Tom McConnell.
745 * checks/Makefile.in (clean): Depends on mostlyclean.
746 (mostlyclean): New goal.
748 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
750 * Makefile.in (DISTFILES): Distribute install.sh.
751 * install.sh: New file, copied from elsewhere.
752 Reported by Assar Westerlund and Kaveh R. Ghazi.
754 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
756 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
757 * acconfig.h: Explain ENABLE_CHANGEWORD.
759 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
760 from code provided by Pete Chown]
761 * m4.h: Add original_text field to u_t variant of union u.
762 Declare TOKEN_DATA_FUNC macro.
763 * builtin.c: Declare changeword.
764 (m4_changeword): New function.
765 * input.c: Include "regex.h", define variables with word regexps.
766 (input_init): Initialize the word regexp.
767 (set_word_regexp): New.
768 (next_token): Declare local variables, use the previous code if
769 default_word_regexp is true. Else, match using a new code. Save
771 * macro.c (expand_token): Ship out original text if not a macro
773 Reported by Krste Asanovic and Pete Chown.
775 [These modifs all depend upon ENABLE_CHANGEWORD]
776 * m4.h: Declare external user_word_regexp.
777 * m4.c: Declare user_word_regexp, and initialize it from
778 --word-regexp or -W, or NULL if not specified.
779 * input.c: Use user_word_regexp if specified, instead of
782 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
785 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
786 * checks/Makefile.in: Empty the suffix list.
787 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
789 * m4.c: Declare nesting_limit and initialize it to 250.
790 Implement -LNUMBER or --nesting-limit=NUMBER to change its
792 * m4.h: Declare nesting_limit as external.
793 * macro.c (expand_macro): Stop execution whenever nesting limit
795 Reported by Bengt Mertensson.
797 * eval.c (evaluate): Diagnose excess characters in eval input.
798 Things like `eval(08)' used to return 0 with no diagnostic.
800 * m4.h: Capitalize first letter of all macro arguments in
803 * m4.c: Declare warning_status, initialize it to 0. Add new
804 option -E, or --fatal-warnings, which sets warning_status to
805 EXIT_FAILURE instead.
806 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
807 EXIT_FAILURE if not otherwise done by header files.
808 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
809 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
810 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
811 argument of all M4ERROR calls.
812 Reported by Noah Friedman.
814 * examples/incl-test.m4: Renamed from incl_test.m4.
815 * examples/include.m4: Include incl-test.m4 instead of
817 * examples/multiquotes.m4: Renamed from multi-quotes.m.
819 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
821 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
822 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
823 also tested it on a Sun Sparc workstation running SunOS 4.x.
825 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
826 49.format check, abusing a `union values' argument with sprintf
827 without selecting the proper field. Now, save the formatting type
828 first, delaying the fetch of the corresponding argument.
829 Reported by Joseph E. Sacco and Tom Quinn.
831 * format.c (format): Remove const from char *fmt declaration when
832 not HAVE_EFGCVT, because a NUL may be forced into it.
834 * m4.h: Declare atof() when not STDC_HEADERS.
835 Reported by Joseph E. Sacco.
837 * Regenerate configure using Autoconf 1.11, this corrects a
838 problem about an incorrect cpp seting on NeXT 3.1.
839 Reported by Alexander Lehmann.
841 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
843 * m4.h (_): Change argument from `x' to `Args'.
845 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
847 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
848 bringing more evil than good on a few systems.
849 Reported by Greg A. Woods.
851 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
853 * m4.h: Rename Args() to _().
854 * m4.h: Remove extern specifier from all function declarations.
856 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
858 * stackovf.c: New file implementing stack-overflow detection.
859 * configure.in: Check for getrlimit, sigaction. If all of
860 standard headers, getrlimit and sigaction, define USE_STACKOVF and
861 substitute ${U}stackovf.o for STACKOVF.
862 * acconfig.h: Declare USE_STACKOVF.
863 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
864 * m4.h: Declare setup_stackovf_trap().
865 * m4.c: Call setup_stackovf_trap().
866 * tests/stackovf_test.sh: New file.
868 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
870 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
872 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
874 Sun Jan 30 14:24:19 1994 (pinard at icule)
876 * m4.h: Remove definition of volatile, not used anymore.
877 Reported by Jim Meyering and Joseph E. Sacco.
879 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
880 of `if ... else /* nothing */' for if macros.
881 Reported by Jim Meyering.
883 * builtin.c (m4_regexp): Reorganize the code for avoiding a
884 warning from gcc about `repl' possibly used before defined.
885 Reported by Jim Meyering.
887 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
888 Reported by Jim Meyering.
890 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
892 * m4.h: Move the conditional definition of volatile after the
893 inclusion of system files, because they may define it first.
895 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
897 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
898 get around a problem with Alpha make seeing a syntax error, there.
899 Reported by Vern Paxson.
901 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
903 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
904 Reported by Richard Stallman.
906 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
908 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
909 instead of AC_HAVE_FUNCS.
910 Reported by Noah Friedman.
912 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
914 * m4.c: Initialize show_help and show_version to zero.
916 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
917 Use them in exit() and usage() calls.
919 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
921 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
922 syserr() macro. Delete errref, add reference_error and M4ERROR.
923 * m4.c: Replace errref, which was returning an input reference
924 string, with reference_error, which prints it on standard error.
925 * builtin.c, output.c: Use errno as second parameter to error,
926 instead of using syserr() with %s.
927 * *.c: Use M4ERROR instead of error: no more errref() with %s.
928 Doing so, the program name appears after the input reference
929 instead of before, which eases M-x next-error processing.
931 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
933 * checks/get-them: Escape braces with backslashes in patterns,
934 because HPUX-9.01 awk needs this.

942 macros, replace error_message_prefix() declaration by errref()'s.
943 Declare xrealloc, for use in errref().
944 * m4.c: Delete error_message_prefix() function, add errref().
945 * *.c: Use error() systematically in place of all error macros,
946 now that error() flushes stdout first. Make needed adjustments.
948 * m4.h: Remove const in sys_errlist[] declaration, it creates
949 conflicts on SGI and Alpha.
950 Reported by Kaveh R. Ghazi.
952 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
954 * m4.c: Include <getopt.h> instead of "getopt.h".
956 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
957 * acconfig.h: New, for documenting HAVE_EFGCVT.
958 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
959 use them wherever appropriate. Also use -I. for compilations.
960 * lib/Makefile.in: Use -I.. for compilations.
961 * *.c: Include <config.h> or "config.h".
963 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
964 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
966 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
968 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
970 * input.c (input_init): Initialize quote and comment strings
971 explicitely instead of calling set_quotes and set_comment: by
972 doing so, we ensure we do not free uninitialized variables.
974 * checks/check-them: Reverse arguments to both diff, so the
975 expected is on the left and the obtained on the right.
977 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
978 macros. Delete declarations for m4error, warning, fatal and
979 internal_error, add declaration for error_message_prefix.
980 * m4.c: Delete m4error, warning, fatal and internal_error
981 routines, add error_message_prefix routine.
982 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
983 warning with WARNING*, fatal with FATAL* and internal_error with
985 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
986 this is not needed anymore.
988 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
989 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
990 and debug_message, add declaration for debug_message_prefix.
991 * debug.c: Remove static specifier for FILE *debug declaration.
992 Delete debug_print and debug_message routines, add
993 debug_message_prefix routine.
994 * builtin.c, debug.c: Replace debug_print routine calls with
995 DEBUG_PRINT* macro calls.
996 * input.c, path.c: Replace debug_message routine calls with
997 DEBUG_MESSAGE* macro calls.
999 * m4.h: Remove inclusion of <varargs.h>.
1000 * debug.c: Include <stdarg.h> or <varargs.h>.
1001 (trace_format): Use stdarg instead of varargs if __STDC__.
1003 * configure.in: Remove checks for vfprintf and _doprnt. These
1004 implementations use varargs tricks which are not portable enough.
1005 * lib/vfprintf.c: Deleted.
1006 * lib/_doprnt.c: Deleted.
1007 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
1008 Reported by Joel Sherrill.
1010 * path.c (add_include_directory): Use xstrdup.
1012 * builtin.c (find_builtin_by_name): Declare static.
1014 * *.[ch]: Add const to a few "char *" declarations.
1016 * configure.in: Remove commented tests for fileno() and fstat().
1017 * debug.c: Remove comments about HAVE_FILENO and HAVE_FSTAT.
1019 * debug.c (debug_flush_files): New.
1020 * m4.h: Declares it.
1021 * builtin.c (m4_syscmd, m4_esyscmd): Use it.
1022 Reported by Nicolas Pioch.
1024 Fri Nov 12 10:02:26 1993 Francois Pinard (pinard@icule)
1026 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
1027 Reported by Joel Sherrill.
1029 * builtin.c (prefix_all_builtins): Instead of the table size, use
1030 the null entry at end for stopping the loop. It was overwritten.
1031 Reported by Andreas Schwab and Jim Meyering.
1033 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
1034 Reported by Kaveh R. Ghazi.

1047 Uong, Ian Taylor, Kaveh R. Ghazi, Tom McConnell and Walter Wong.
1049 Mon Nov 8 21:11:44 1993 Francois Pinard (pinard@icule)
1051 * m4.h: Define strchr and strrchr in terms of index and rindex,
1052 instead of the other way around.
1053 * builtin.c, m4.c, path.c: Use strchr instead of index.
1055 * input.c (next_char): Remove a "break;" after a "return ...;".
1056 Reported by Tom McConnell.
1058 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
1062 * configure.in: Do not copy check files in the build hierarchy.
1063 * checks/check-them: Identify the m4 version being checked. For
1064 finding m4, look in $PATH instead of in the parent directory.
1065 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
1066 * checks/Makefile.in (.all-stamp): Always create check files in
1067 the source hierarchy, not anymore in the build hierarchy.
1068 (check): cd to the source hierarchy before performing checks.
1069 Do not copy nor clean COPYING anymore, take it from `..'.
1070 Reported by Tom McConnell.
1072 * Makefile.in (Makefile): Use $(SHELL).
1073 (config.status): Use $(SHELL). Use "config.status --recheck"
1074 instead of "configure --no-create", which is obsolete.
1075 Reported by Tom McConnell.
1077 Fri Nov 5 09:49:30 1993 Francois Pinard (pinard@compy.IRO.UMontreal.CA)
1079 * m4.c (usage): Use "%s" instead of "m4" in format string.

1083 Reported by Pierre Gaumond.
1084 Reported by Jim Meyering.
1085 Reported by Tom McConnell.

1266 * Makefile.in (texclean, mostlyclean): New goals.
1268 * Makefile.in (clean): Remove clutter from ansi2knr.
1269 Reported by Pierre Gaumond.

1285 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
1288 This is still a beta release for the future GNU m4 version 1.1.
1290 * lib/alloca.c: New, from elsewhere.
1291 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
1293 * m4.h: Do not define index/rindex if already defined. If
1294 FALSE/TRUE are already defined, do not redefine them, but merely
1295 define boolean typedef to int.
1297 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
1298 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
1299 because some C compilers do not like connectives with #ifdef.
1300 * m4.h: Define `volatile' only if __GNUC__, instead of once for
1301 __GNUC__ and once for __STDC__.
1302 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
1304 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
1305 Makefile dependencies. Without it, make keeps destroying and
1306 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
1308 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
1309 to diversion/DIVERSION, this was a spelling error.
1311 * m4.c: Declare version[], remove #include "version.h".
1312 * version.h: Deleted.
1313 * Makefile.in: Remove references to version.h.
1315 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
1316 production, by using a simpler and more robust algorithm. This
1317 solves the problem of synclines sometimes written in the middle of
1318 an output line. Delete sync_line() and output_lines variable.
1319 * m4.h: Remove sync_line prototype and output_lines declaration.
1320 * input.c (next_char), output.c (shipout_text): Remove references
1322 * input.c (push_file, pop_file): Merely put the value -1 in
1323 output_current_line instead of calling sync_line, for delaying a
1324 single `#line NUM FILE' before next output line. Do not test
1325 for sync_output, because this is unnecessary clutter.
1326 * output.c (make_divertion, insert_divertion): Idem.
1327 * input.c: Rename must_advance_line to start_of_input_line, for
1330 * debug.c (trace_header): Select a new debug line format, which
1331 better complies with GNU standards for formatting error messages.
1332 With option `-dfl', M-x next-error might be used on the output.
1333 * m4.c (vmesg): Adjust format of error output to GNU standards.
1334 * m4.texinfo: Adjust examples for `make check' to work.
1336 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
1337 case for enum debug_info constants, which were all lower case.
1339 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
1341 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
1342 collected patches. I tried a few times using newer regex.[ch], it
1343 mysteriously stopped aborting with this one. Insecure feeling...
1344 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
1346 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
1348 * m4.c: Change `--no-warnings' to `--silent'.
1349 Reported by David MacKenzie.
1351 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
1352 leave it off for now. See comment in m4.c for justification.
1353 Reported by David MacKenzie.
1355 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
1356 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
1358 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
1360 * Makefile.in: Ensure recursive cleaning is done before local
1361 cleaning for all clean goals.
1363 * builtin.c (ntoa): Ensure the value is always interpreted as a
1364 signed quantity, whatever the radix is.
1366 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
1368 * builtin.c, format.c, input.c: Split long lines.
1369 * m4.c: Use typedef macro_definition instead of struct
1371 * symtab.c: Use typedef symbol instead of struct symbol.
1373 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
1375 * *.[ch]: Remove all trailing whitespace, in code and comments.
1377 * configure.in: Find some awk.
1378 * Makefile.in: Add $(AWK) to MDEFINES.
1379 * checks/Makefile.in: Transmit $(AWK) to get_them.
1380 * checks/get_them: Use $AWK instead of gawk. Add a close in the
1381 awk script when switching files, because without this, mawk runs
1382 out of file descriptors.
1384 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
1386 * Makefile.in (realclean): Delete m4.info*.
1387 Reported by Jim Meyering.
1389 * Makefile.in: Adjust and link with checks/Makefile.
1390 * checks/Makefile.in: New.
1391 * configure.in: Output checks/Makefile.
1393 * checks/get_them: Have the dnl header of each test more
1394 recognizable by next-error, also use a better message.
1396 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
1398 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
1399 And use that only if __GNUC__ since we're using it's GCC-specific
1400 semantics that tell the compiler the associated function doesn't
1403 * builtin.c (substitute): Don't use character as an array index.
1404 (dumpdef_cmp): Make formal arguments `const void *' to avoid
1405 warnings with gcc -W -Wall on systems with qsort prototype.
1406 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
1409 * eval.c (most functions): Add parentheses to assignments used
1410 as truth values go avoid warnings from gcc -Wall.
1412 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
1413 any functions that don't need external scope.
1415 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
1416 (many functions and arrays): Declare `const'.
1418 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
1420 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
1421 removing the declaration from m4.h. Also rename false to FALSE
1424 * lib/Makefile.in (Makefile): New goal.
1426 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
1427 so heavily loaded. It gets more easily overridable, calling make.
1428 Reported by Jim Meyering.
1430 * Makefile.in (dist): Get .fname from the current directory name,
1431 instead of from version.h. I need updating many files manually,
1432 when the version changes, version.h is just one of them.
1434 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
1436 * m4.h: Remove the tag `boolean' on the enum introducing typedef
1437 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
1438 Reported by Tom McConnell.
1440 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
1442 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
1443 39.cleardiv, which were describing missing or spurious newlines.
1444 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
1445 do not depend on machine word size, `/bin/false' implementation,
1446 or `wc' output format. `make check' is more dependable, now.
1448 * checks/check_them: Summarize the failed tests by listing their
1449 name, at end. If none, issue `All checks successful'. Output
1450 `Checking' instead of `Input file:'.
1452 * checks/get_them, checks/check_them: Reindented.
1454 * Makefile.in (dist): chmod a+r before making the tar file.
1456 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
1458 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
1460 * input.c (next_token): Reinitialize token_buttom just after using
1461 it as a watermark with obstack_free. Or else, a future token, big
1462 enough for triggering reallocation of the obstack chunk, could
1463 void the initialized value of token_buttom, later causing panic in
1464 obstack_free. Rename token_buttom to token_bottom everywhere.
1466 * m4.h: Before declaring errno, first include <errno.h> and
1467 ensure that it does not define errno.
1468 Reported by Richard Stallman.
1470 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
1472 * builtin.c: Define and use DECLARE macro for builtins.
1474 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
1475 argument, this is a common idiom for introducing long comments.
1477 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
1478 arguments. The last argument was silently ignored.
1480 * m4.c (cmd_error): Add a missing semicolon before va_end().
1482 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
1484 * Makefile.in: Now handle protoized sources. Define and use U.
1485 Compile and use ansi2knr with old compilers. Update DISTFILES.
1486 Add `aclocal.m4' to `configure' dependencies.
1487 * ansi2knr.c: New, from Ghostscript distribution.
1488 * configure.in: Define U through FP_PROTOTYPES for old compilers.
1489 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
1490 * aclocal.m4: New, provide FP_PROTOTYPES.
1491 * m4.h: Conditionnaly protoized through Args, save for varags.
1492 * builtin.c: Protoized. Then:
1493 Include <sys/types.h> if size_t is not defined, before "regex.h".

1495 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
1496 (m4_regexp): Add const to `msg' declaration.

1502 * m4.c: Protoized, save for varargs. Then:
1503 (xfree): Accept void * instead of char *.
1504 (xmalloc): Return void * instead of char *.
1505 (xrealloc): Accept and return void * instead of char *.
1506 * macro.c: Protoized.
1507 * output.c: Protoized.
1508 * path.c: Protoized. Then cast some (char *) over xmalloc's.
1509 * symtab.c: Protoized.
1511 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
1513 * m4.texinfo: Remove directory from diagnostics in 30.include,
1514 51.eval, 56.errprint and 57.m4exit tests.
1516 * m4.h: Remove declarations for int or void system functions, they
1517 cause more conflicting trouble than they make good.
1519 * configure.in: Avoid configuration header file. Add some tests.
1520 * m4.h: Remove #include "config.h".
1521 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
1522 Then, rewritten for better compliance with GNU standards.
1524 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
1526 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
1527 because of a misplaced #endif.

1545 * m4.c: Changes in order to use a newer getopt.h.
1546 Reported by David MacKenzie.

1558 * Makefile.in (check): Add m4 as dependency.
1560 * m4.c: Accept --no-warnings instead of --no_warnings, and
1561 --no-gnu-extensions instead of --no_gnu_extensions. Make the
1562 usage message more informative.
1563 Reported by David MacKenzie.

1579 Reported by Richard Stallman.
1581 * config/hmake-unicos, config/s-unicos.h: New files.
1582 Reported by Hal Peterson.
1584 * eval.c (exp_term): Have N^0 return 1.
1585 Reported by Michael Fetterman.
1587 * eval.c, input.c, m4.h: Remove last comma in enums.
1588 Reported by Mike Lijewski.

1595 reports and feedback.
1597 * Uses GNU configure, taken from the gdb distribution.
1599 * Uses GNU getopt(), with long option names.
1601 * The -Q/+quiet option is added, which suppresses warnings about
1602 missing or superflous arguments to built-in macros.

1606 * The built-in format can now be configured to use sprintf as
1607 the formatting engine, for systems without [efg]cvt(3).
