155 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
156 preserving, but case insensitive, so generating html docs per node
157 clashes between Index.html, the node file, and index.html, the
158 top-level of the document tree...
159 (Index macro): ...so renamed to this. Changed all references.

227 * config-h.in: ...this to better support DOS 8.3 file systems.
228 * acconfig.h: Removed.
229 * configure.in: Renamed to...
230 * configure.ac: ...this, and AC_DEFINE used to declare config.h

247 2005-02-03 Noah Misch <noah@cs.caltech.edu>
249 * src/output.c (mkstemp): Make non-static, and build regardless of

253 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
255 * configure.in (AC_CHECK_HEADERS): Commit works best when you save

259 * src/m4.c: And include them as appropriate.
262 2004-09-09 Andreas Schwab <schwab@suse.de>

412 Remove the sed filter after ansi2knr for debug.c. Use $O instead
413 of $U, put underline in extensions rather than in basenames. Use
414 implicit rules, now that regularity makes this possible.
415 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
416 of ansi2knr whenever it is needed.
417 * configure.in: Adjusted for correct STACKOVF substitution.
418 * src/debug.c (trace_format): When not __STDC__, use (...) as a

467 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
469 * src/stackovf.c: Declare the handler_t typedef earlier in the

505 which is repeated in both goals.
507 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
511 * Makefile.in: Group all *clean-recursive goals in one, using sed

582 previous prefix_all_buitins function, while making entries in the
583 symbol table, but not modifying the builtin description itself.
585 * src/freeze.c (reload_frozen_state): Add a useless `break;',
586 because *many* compilers do not accept an empty `default:'.
587 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
588 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
590 * configure.in: Use AC_TYPE_SIGNAL.
591 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
592 Reported by Robert Bernstein.
594 * checks/Makefile.in (check): Modify PATH so check-them will find
595 m4 in the src directory.
596 * Makefile.in (check): Don't.
597 Reported by Akiko Matsushita and Jim Meyering.
599 * src/output.c (make_room_for, output_character_helper): New
600 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
601 a per buffer MAXIMUM_BUFFER_SIZE.
603 * src/output.c (output_text): New function, for optimizing the
604 output of strings of characters. Use it.
606 Tue Aug 30 01:44:29 1994 Francois Pinard (pinard@icule)
608 * doc, src: New directories reorganizing the distribution.
609 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
611 * Makefile.in: Adjusted.
612 * configure.in: Configure new Makefiles.
614 * m4.h: Declare STRING typedef. Use it for comment and quote
615 strings, adjusting all references. (This is the rudiments of a
616 beginning for the eventual withdrawal of NUL terminated strings.)
617 * output.c (shipout_text): Accept a length parameter, and use it.
618 All callers adjusted.
620 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
622 * m4.h: Include <unistd.h> if it exists.
625 Clean up for current_diversion variable:
626 * output.c: Move current_diversion from builtin.c.
627 * m4.h: Declare current_diversion so builtin.c can access it.
628 * output.c (output_init, make_diversion): Initialize or update
630 * builtin.c (builtin_init, m4_divert): Leave current_diversion
633 Remove limit on number of diversions:
634 * output.c: Replace ndiversion by diversions, declare it.
635 (output_init): Allocate only diversion 0.
636 (make_diversion): Allocate new diversions as needed.
637 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
638 * m4.c: Still accept -N, but do nothing with it.
639 Reported by David MacKenzie.
642 * output.c (freeze_diversions): New function.
643 * m4.h: Declare freeze_diversions.
644 * freeze.c: Document frozen file format, revise it, call
645 freeze_diversions to add diversions to frozen format, and code to
646 reload them properly.
647 * m4.c: Do not undivert automatically at end when status being
648 frozen. Do not call builtin_init when reloading frozen state.
650 Speed up diversion processing:
651 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
652 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
653 structure and variables, cached variables out of output_diversion,
654 reallocate_diversion_for and OUTPUT_CHARACTER.
655 (shipout_text, make_diversion, insert_diversion): Adapted to new
657 (insert_file): Use better buffering.
658 Reported by David MacKenzie.
660 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
662 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
663 dist works from another build directory.
665 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
667 * symtab.c (hack_all_symbols): Use hash_table_size instead of
668 constant HASHMAX, for -H option to work better.
670 * builtin.c (DECLARE): Simplify by using _ ().
672 * freeze.c: New file.
673 * Makefile.in: Compile it, distribute it.
674 * m4.c: Recognize, document and process --freeze-state (-F) and
675 --reload-state (-R) options. Pass a true flag to builtin_init
676 only if no reloading some state.
677 * builtin.c (define_builtin): Remove static specifier.
678 (find_builtin_by_name): Remove static specifier.
679 (builtin_init): Accept and obey a flag argument.
680 * m4.h: Add declarations for freeze.c, changes for builtin.c.
682 Wed Aug 24 16:14:19 1994 Francois Pinard (pinard@icule)
684 * builtin.c (dumpdef_cmp): Rewrite so the cast protect the const
687 * configure.in: Implement --with-dmalloc.
688 * acconfig.h: Document WITH_DMALLOC.
689 * m4.h: Add code for when WITH_DMALLOC.
691 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
693 * m4.c (long_options): Use "error-output", the dash was missing.
694 Reported by Akiko Matsushita.
696 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
698 * m4.h: Include <sys/types.h>.
699 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
700 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
702 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
704 * builtin.c (dump_args): Declare len as size_t, not int.
706 * debug.c: Prototype the forward declaration of debug_set_file.
708 * builtin.c (m4_undivert): Replace div by file, for avoiding the
709 shadowing of this variable.
710 * output.c (insert_diversion): Idem.
712 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
713 (input_init): Duplicate default quote and comment strings.
714 (set_quotes): Free previous quote strings in all cases. Duplicate
715 even default quote strings.
716 (set_comment): Free previous comment strings in all cases.
717 Duplicate even default comment strings.
719 * configure.in: Updated for Autoconf 2.0.
720 * Makefile.in (distclean-local): Also delete config.cache.
722 * m4.c (usage): Reorganize the --help output by topic. Include a
723 description for debugging flags.
725 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
727 * configure.in: If sigaction is available and SA_ONSTACK defined,
728 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
729 defined, use sigvec. Else don't compile stackovf.c.
730 * stackovf.c (setup_stackovf_trap): Idem.
731 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
734 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
736 * m4.c (usage): Replace printf par fputs.
738 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
742 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
744 * configure.in: Check for sigaction and sigvec. Add a new delayed
745 check for RLIMIT_STACK, combine in the checking for getrlimit.
746 All those things are not universally available.
747 * stackovf.c: Split setting up the trap handler and catching
748 signals, for better taking care of various configure outcomes.
749 * examples/stackovf.sh: Correct a typo.
750 Reported by Eric Backus, Jim Avera and Jim Meyering.
752 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
754 * ansi2knr.c: New version sent by its author, Peter Deutsch.
756 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
758 * Makefile.in: Modify so parallel make will not try making
759 lib/libm4.a twice simultaneously.
760 Reported by Jim Meyering.
762 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
764 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
765 error message, for when no code possibility exists. Even if this
766 line is completely #ifdef'ed out, it brings a syntax error.
767 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
769 * Makefile.in (install): Have install depend on all too, for lib
770 to be remade as needed.
772 * examples/stackovf.sh: Try ksh, bsh and bash for shells
773 providing ulimit, instead of using only ksh.
774 Reported by Jim Avera and Joseph E. Sacco.
776 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
778 * Makefile.in (check): Have it depend on all instead of m4. In
779 this way, a change in lib will be detected and processed.
781 * builtin.c (numeric_arg): Use strtol and verify the conversion,
782 instead of using sscanf which stops as soon as there is a
783 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
784 and divert(1xyzzy) were all accepted without any warning or error
786 * m4.h: Declare strtol as long if not including stdlib.h.
787 * configure.in: Check for limits.h, and replace strtol if missing.
788 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
789 * lib/strtol.c: New file, from elsewhere.
790 Reported by Andreas Schwab.
792 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
794 * macro.c (expand_macro): Cast value to (boolean) prior to
795 assigning it to traced.
796 Reported by Tom McConnell.
798 * Makefile.in (m4): Always make all in lib first.
799 Reported by Jim Meyering.
801 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
803 * stackovf.c: Isolated OS-dependent sections; Improved portability,
804 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
805 handlers), and a default error message if the fault address is not
806 available (when neither siginfo.h nor BSD sigcontext are supported).
807 * configure.in: Changes for stackovf.h: Check for sigcontext,
808 sigaction, sigstack, and define rlim_t as int if necessary.
809 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
810 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
811 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
813 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
815 * configure.in: Use AC_SET_MAKE.
816 * Makefile.in: Use @SET_MAKE@.
817 Reported by Jim Meyering.
819 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
820 Reported by Ian Taylor.
822 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
824 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
825 because siginfo.h is unrelated to standard headers, and siginfo.h
826 is already checked for.
827 Reported by Joseph E. Sacco.
829 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
831 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
834 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
836 * builtin.c (substitute): Use \& to represent this part of the
837 string which was matched by the whole regexp, instead of
838 representing the whole string. Any usage of \0 issues a warning
839 and acts like \&, it will disappear in some subsequent release.
841 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
843 * m4.c: Complete prototype for forwarded declaration of usage.
845 * input.c (init_macro_token): Correct own reference in error
846 message. Previous name get_macro_func was referred to instead.
847 (next_char): Correct own reference in error message. Previous
848 name advance_input was referred to instead.
850 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
851 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
852 and_term, not_term, logical_not_term, cmp_term, shift_term,
853 add_term, mult_term, exp_term, unary_term, simple_term): Add
854 prototype to forwarded declarations. Declare parameter v1 as
855 eval_t * instead of int *. Same for local variable v2 in dyadic
856 functions. Same for result in exp_term.
857 * builtin.c (m4_eval): Declare value as eval_t instead of int.
858 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
859 unsigned_eval_t instead of unsigned int. Change casts accordingly.
860 (shipout_int): Cast first argument of ntoa to eval_t.
861 Reported by Thorsten Ohl.
863 * macro.c: Complete the prototypes of forwarded expand_macro and
865 Reported by Thorsten Ohl.
867 * m4.h: Define voidstar as void * or char * depending on __STDC__.
868 The Ultrix 3.1 compiler cannot do much with void pointers.
870 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
871 * m4.c (xfree): Replace void * by voidstar.
872 Reported by Tom McConnell.
874 * ansi2knr.1: New, from elsewhere.
875 * Makefile.in (DISTFILES): Distribute ansi2knr.1
877 * Makefile.in (stamp-h.in): Avoid running ./config.status if
878 stamp-h does not exist yet. This avoids running it a second time
879 just after the initial ./configure.
880 Reported by David MacKenzie and Tom McConnell.
882 * m4.h: Replace the enum debug_info declaration with a series of
883 #define's. The Ultrix 3.1 compiler would otherwise need casting
884 (int) to most references, when used in expressions.
885 Reported by Tom McConnell.
887 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
889 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
890 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
891 calls the compiler. Previously, FP_PROTOTYPES was only calling
892 the preprocessor; by not being subject to CFLAGS, this was
893 discouraging those flags asking for ANSI compilation.
894 * acconfig.h: Document HAVE_PROTOTYPES.
895 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
896 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
897 Reported by Eric Backus.
899 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
900 from the environment. Default CFLAGS to -g if not set.
901 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
902 * lib/Makefile.in: Have CFLAGS substituted from configure.
903 Reported by Eric Backus and Tom McConnell.
905 * configure.in: m4_undefine changeword before using AC_ENABLE.
907 * m4.h: Declare prototypes for error (for ANSI compilers only),
908 prefix_all_builtins and reference_error.
909 Reported by Tom McConnell.
911 * input.c (set_word_regexp): Do not try to initialize the array
912 test from a string, this does not work with non-ANSI compilers.
913 Reported by Eric Backus.
915 * Makefile.in (dist): Clean examples/ before saving it.
916 (distclean-local): Also remove stamp-h.
917 Reported by Eric Backus.
919 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
921 Reported by Tom McConnell.
923 * checks/Makefile.in (clean): Depends on mostlyclean.
924 (mostlyclean): New goal.
926 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
928 * Makefile.in (DISTFILES): Distribute install.sh.
929 * install.sh: New file, copied from elsewhere.
930 Reported by Assar Westerlund and Kaveh R. Ghazi.
932 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
934 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
935 * acconfig.h: Explain ENABLE_CHANGEWORD.
937 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
938 from code provided by Pete Chown]
939 * m4.h: Add original_text field to u_t variant of union u.
940 Declare TOKEN_DATA_FUNC macro.
941 * builtin.c: Declare changeword.
942 (m4_changeword): New function.
943 * input.c: Include "regex.h", define variables with word regexps.
944 (input_init): Initialize the word regexp.
945 (set_word_regexp): New.
946 (next_token): Declare local variables, use the previous code if
947 default_word_regexp is true. Else, match using a new code. Save
949 * macro.c (expand_token): Ship out original text if not a macro
951 Reported by Krste Asanovic and Pete Chown.
953 [These modifs all depend upon ENABLE_CHANGEWORD]
954 * m4.h: Declare external user_word_regexp.
955 * m4.c: Declare user_word_regexp, and initialize it from
956 --word-regexp or -W, or NULL if not specified.
957 * input.c: Use user_word_regexp if specified, instead of
960 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
963 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
964 * checks/Makefile.in: Empty the suffix list.
965 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
967 * m4.c: Declare nesting_limit and initialize it to 250.
968 Implement -LNUMBER or --nesting-limit=NUMBER to change its
970 * m4.h: Declare nesting_limit as external.
971 * macro.c (expand_macro): Stop execution whenever nesting limit
973 Reported by Bengt Mertensson.
975 * eval.c (evaluate): Diagnose excess characters in eval input.
976 Things like `eval(08)' used to return 0 with no diagnostic.
978 * m4.h: Capitalize first letter of all macro arguments in
981 * m4.c: Declare warning_status, initialize it to 0. Add new
982 option -E, or --fatal-warnings, which sets warning_status to
983 EXIT_FAILURE instead.
984 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
985 EXIT_FAILURE if not otherwise done by header files.
986 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
987 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
988 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
989 argument of all M4ERROR calls.
990 Reported by Noah Friedman.
992 * examples/incl-test.m4: Renamed from incl_test.m4.
993 * examples/include.m4: Include incl-test.m4 instead of
995 * examples/multiquotes.m4: Renamed from multi-quotes.m.
997 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
999 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
1000 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
1001 also tested it on a Sun Sparc workstation running SunOS 4.x.
1003 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
1004 49.format check, abusing a `union values' argument with sprintf
1005 without selecting the proper field. Now, save the formatting type
1006 first, delaying the fetch of the corresponding argument.
1007 Reported by Joseph E. Sacco and Tom Quinn.
1009 * format.c (format): Remove const from char *fmt declaration when
1010 not HAVE_EFGCVT, because a NUL may be forced into it.
1012 * m4.h: Declare atof() when not STDC_HEADERS.
1013 Reported by Joseph E. Sacco.
1015 * Regenerate configure using Autoconf 1.11, this corrects a
1016 problem about an incorrect cpp seting on NeXT 3.1.
1017 Reported by Alexander Lehmann.
1019 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
1021 * m4.h (_): Change argument from `x' to `Args'.
1023 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
1025 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
1026 bringing more evil than good on a few systems.
1027 Reported by Greg A. Woods.
1029 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
1031 * m4.h: Rename Args() to _().
1032 * m4.h: Remove extern specifier from all function declarations.
1034 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
1036 * stackovf.c: New file implementing stack-overflow detection.
1037 * configure.in: Check for getrlimit, sigaction. If all of
1038 standard headers, getrlimit and sigaction, define USE_STACKOVF and
1039 substitute ${U}stackovf.o for STACKOVF.
1040 * acconfig.h: Declare USE_STACKOVF.
1041 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
1042 * m4.h: Declare setup_stackovf_trap().
1043 * m4.c: Call setup_stackovf_trap().
1044 * tests/stackovf_test.sh: New file.
1046 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
1048 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
1050 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
1052 Sun Jan 30 14:24:19 1994 (pinard at icule)
1054 * m4.h: Remove definition of volatile, not used anymore.
1055 Reported by Jim Meyering and Joseph E. Sacco.
1057 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
1058 of `if ... else /* nothing */' for if macros.
1059 Reported by Jim Meyering.
1061 * builtin.c (m4_regexp): Reorganize the code for avoiding a
1062 warning from gcc about `repl' possibly used before defined.
1063 Reported by Jim Meyering.
1065 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
1066 Reported by Jim Meyering.
1068 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
1070 * m4.h: Move the conditional definition of volatile after the
1071 inclusion of system files, because they may define it first.
1073 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
1075 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
1076 get around a problem with Alpha make seeing a syntax error, there.
1077 Reported by Vern Paxson.
1079 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
1081 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
1082 Reported by Richard Stallman.
1084 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
1086 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
1087 instead of AC_HAVE_FUNCS.
1088 Reported by Noah Friedman.
1090 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
1092 * m4.c: Initialize show_help and show_version to zero.
1094 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
1095 Use them in exit() and usage() calls.
1097 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
1099 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
1100 syserr() macro. Delete errref, add reference_error and M4ERROR.
1101 * m4.c: Replace errref, which was returning an input reference
1102 string, with reference_error, which prints it on standard error.
1103 * builtin.c, output.c: Use errno as second parameter to error,
1104 instead of using syserr() with %s.
1105 * *.c: Use M4ERROR instead of error: no more errref() with %s.
1106 Doing so, the program name appears after the input reference
1107 instead of before, which eases M-x next-error processing.
1109 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
1111 * checks/get-them: Escape braces with backslashes in patterns,
1112 because HPUX-9.01 awk needs this.

1115 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
1117 * builtin.c: Declare "FILE *popen ();".

1121 Declare xrealloc, for use in errref().
1122 * m4.c: Delete error_message_prefix() function, add errref().
1123 * *.c: Use error() systematically in place of all error macros,
1124 now that error() flushes stdout first. Make needed adjustments.
1126 * m4.h: Remove const in sys_errlist[] declaration, it creates
1127 conflicts on SGI and Alpha.
1128 Reported by Kaveh R. Ghazi.

1146 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
1148 * input.c (input_init): Initialize quote and comment strings
1149 explicitely instead of calling set_quotes and set_comment: by

1153 expected is on the left and the obtained on the right.
1155 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

1161 warning with WARNING*, fatal with FATAL* and internal_error with
1163 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
1164 this is not needed anymore.

1170 Delete debug_print and debug_message routines, add
1171 debug_message_prefix routine.
1172 * builtin.c, debug.c: Replace debug_print routine calls with

1179 (trace_format): Use stdarg instead of varargs if __STDC__.
1181 * configure.in: Remove checks for vfprintf and _doprnt. These

1204 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
1205 Reported by Joel Sherrill.
1207 * builtin.c (prefix_all_builtins): Instead of the table size, use
1208 the null entry at end for stopping the loop. It was overwritten.
1209 Reported by Andreas Schwab and Jim Meyering.
1211 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
1212 Reported by Kaveh R. Ghazi.

1234 Reported by Tom McConnell.
1236 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
1240 * configure.in: Do not copy check files in the build hierarchy.
1241 * checks/check-them: Identify the m4 version being checked. For
1242 finding m4, look in $PATH instead of in the parent directory.
1243 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
1244 * checks/Makefile.in (.all-stamp): Always create check files in
1245 the source hierarchy, not anymore in the build hierarchy.

1468 * lib/alloca.c: New, from elsewhere.
1469 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
1471 * m4.h: Do not define index/rindex if already defined. If
1472 FALSE/TRUE are already defined, do not redefine them, but merely
1473 define boolean typedef to int.
1475 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
1476 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
1477 because some C compilers do not like connectives with #ifdef.
1478 * m4.h: Define `volatile' only if __GNUC__, instead of once for
1479 __GNUC__ and once for __STDC__.
1480 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
1482 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
1483 Makefile dependencies. Without it, make keeps destroying and
1484 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
1486 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
1487 to diversion/DIVERSION, this was a spelling error.
1489 * m4.c: Declare version[], remove #include "version.h".
1490 * version.h: Deleted.
1491 * Makefile.in: Remove references to version.h.
1493 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
1494 production, by using a simpler and more robust algorithm. This
1495 solves the problem of synclines sometimes written in the middle of
1496 an output line. Delete sync_line() and output_lines variable.
1497 * m4.h: Remove sync_line prototype and output_lines declaration.
1498 * input.c (next_char), output.c (shipout_text): Remove references
1500 * input.c (push_file, pop_file): Merely put the value -1 in
1501 output_current_line instead of calling sync_line, for delaying a
1502 single `#line NUM FILE' before next output line. Do not test
1503 for sync_output, because this is unnecessary clutter.
1504 * output.c (make_divertion, insert_divertion): Idem.
1505 * input.c: Rename must_advance_line to start_of_input_line, for
1508 * debug.c (trace_header): Select a new debug line format, which
1509 better complies with GNU standards for formatting error messages.
1510 With option `-dfl', M-x next-error might be used on the output.
1511 * m4.c (vmesg): Adjust format of error output to GNU standards.
1512 * m4.texinfo: Adjust examples for `make check' to work.
1514 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
1515 case for enum debug_info constants, which were all lower case.
1517 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
1519 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
1520 collected patches. I tried a few times using newer regex.[ch], it
1521 mysteriously stopped aborting with this one. Insecure feeling...
1522 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
1524 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
1526 * m4.c: Change `--no-warnings' to `--silent'.
1527 Reported by David MacKenzie.
1529 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
1530 leave it off for now. See comment in m4.c for justification.
1531 Reported by David MacKenzie.
1533 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
1534 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
1536 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
1538 * Makefile.in: Ensure recursive cleaning is done before local
1539 cleaning for all clean goals.
1541 * builtin.c (ntoa): Ensure the value is always interpreted as a
1542 signed quantity, whatever the radix is.
1544 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
1546 * builtin.c, format.c, input.c: Split long lines.
1547 * m4.c: Use typedef macro_definition instead of struct
1549 * symtab.c: Use typedef symbol instead of struct symbol.
1551 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
1553 * *.[ch]: Remove all trailing whitespace, in code and comments.
1555 * configure.in: Find some awk.
1556 * Makefile.in: Add $(AWK) to MDEFINES.
1557 * checks/Makefile.in: Transmit $(AWK) to get_them.
1558 * checks/get_them: Use $AWK instead of gawk. Add a close in the
1559 awk script when switching files, because without this, mawk runs
1560 out of file descriptors.
1562 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
1564 * Makefile.in (realclean): Delete m4.info*.
1565 Reported by Jim Meyering.
1567 * Makefile.in: Adjust and link with checks/Makefile.
1568 * checks/Makefile.in: New.
1569 * configure.in: Output checks/Makefile.
1571 * checks/get_them: Have the dnl header of each test more
1572 recognizable by next-error, also use a better message.
1574 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
1576 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
1577 And use that only if __GNUC__ since we're using it's GCC-specific
1578 semantics that tell the compiler the associated function doesn't
1581 * builtin.c (substitute): Don't use character as an array index.
1582 (dumpdef_cmp): Make formal arguments `const void *' to avoid
1583 warnings with gcc -W -Wall on systems with qsort prototype.
1584 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
1587 * eval.c (most functions): Add parentheses to assignments used
1588 as truth values go avoid warnings from gcc -Wall.
1590 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
1591 any functions that don't need external scope.
1593 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
1594 (many functions and arrays): Declare `const'.
1596 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
1598 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
1599 removing the declaration from m4.h. Also rename false to FALSE
1602 * lib/Makefile.in (Makefile): New goal.
1604 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
1605 so heavily loaded. It gets more easily overridable, calling make.
1606 Reported by Jim Meyering.
1608 * Makefile.in (dist): Get .fname from the current directory name,
1609 instead of from version.h. I need updating many files manually,
1610 when the version changes, version.h is just one of them.
1612 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
1614 * m4.h: Remove the tag `boolean' on the enum introducing typedef
1615 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
1616 Reported by Tom McConnell.
1618 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
1620 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
1621 39.cleardiv, which were describing missing or spurious newlines.
1622 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
1623 do not depend on machine word size, `/bin/false' implementation,
1624 or `wc' output format. `make check' is more dependable, now.
1626 * checks/check_them: Summarize the failed tests by listing their
1627 name, at end. If none, issue `All checks successful'. Output
1628 `Checking' instead of `Input file:'.

1638 * input.c (next_token): Reinitialize token_buttom just after using
1639 it as a watermark with obstack_free. Or else, a future token, big
1640 enough for triggering reallocation of the obstack chunk, could
1641 void the initialized value of token_buttom, later causing panic in
1642 obstack_free. Rename token_buttom to token_bottom everywhere.
1644 * m4.h: Before declaring errno, first include <errno.h> and
1645 ensure that it does not define errno.
1646 Reported by Richard Stallman.

1692 51.eval, 56.errprint and 57.m4exit tests.
1694 * m4.h: Remove declarations for int or void system functions, they
