1640 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1641 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

1659 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1660 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1661 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1662 of $U, put underline in extensions rather than in basenames. Use
1663 implicit rules, now that regularity makes this possible.
1664 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1665 of ansi2knr whenever it is needed.
1666 * configure.in: Adjusted for correct STACKOVF substitution.
1667 * src/debug.c (trace_format): When not __STDC__, use (...) as a

1766 Reported by Kaveh R. Ghazi.
1768 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1769 4.1.3 requires -ldl to link even ansik2nr, and we need a way to

1773 * Makefile.in (stamp-h.in): Idem.
1775 * Makefile.in (distclean, realclean): Force serial execution of

1829 * src/m4.h: Adjust declaration for prefix_all_buitins.
1830 * src/builtin.c (builtin_init): Merge in functionality from
1831 previous prefix_all_buitins function, while making entries in the
1832 symbol table, but not modifying the builtin description itself.
1834 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1835 because *many* compilers do not accept an empty `default:'.
1836 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1837 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1839 * configure.in: Use AC_TYPE_SIGNAL.

1892 * m4.h: Declare freeze_diversions.
1893 * freeze.c: Document frozen file format, revise it, call
1894 freeze_diversions to add diversions to frozen format, and code to
1895 reload them properly.
1896 * m4.c: Do not undivert automatically at end when status being
1897 frozen. Do not call builtin_init when reloading frozen state.
1899 Speed up diversion processing:
1900 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
1901 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion

1922 * Makefile.in: Compile it, distribute it.
1923 * m4.c: Recognize, document and process --freeze-state (-F) and

1925 only if no reloading some state.
1926 * builtin.c (define_builtin): Remove static specifier.
1927 (find_builtin_by_name): Remove static specifier.

1997 signals, for better taking care of various configure outcomes.
1998 * examples/stackovf.sh: Correct a typo.

2013 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2014 error message, for when no code possibility exists. Even if this

2025 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2027 * Makefile.in (check): Have it depend on all instead of m4. In
2028 this way, a change in lib will be detected and processed.
2030 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2031 instead of using sscanf which stops as soon as there is a
2032 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2033 and divert(1xyzzy) were all accepted without any warning or error
2035 * m4.h: Declare strtol as long if not including stdlib.h.
2036 * configure.in: Check for limits.h, and replace strtol if missing.
2037 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.

2052 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2053 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2054 handlers), and a default error message if the fault address is not
2055 available (when neither siginfo.h nor BSD sigcontext are supported).
2056 * configure.in: Changes for stackovf.h: Check for sigcontext,
2057 sigaction, sigstack, and define rlim_t as int if necessary.
2058 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.

2073 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2074 because siginfo.h is unrelated to standard headers, and siginfo.h
2075 is already checked for.
2076 Reported by Joseph E. Sacco.
2078 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2080 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2083 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2085 * builtin.c (substitute): Use \& to represent this part of the
2086 string which was matched by the whole regexp, instead of
2087 representing the whole string. Any usage of \0 issues a warning
2088 and acts like \&, it will disappear in some subsequent release.

2102 add_term, mult_term, exp_term, unary_term, simple_term): Add
2103 prototype to forwarded declarations. Declare parameter v1 as

2105 functions. Same for result in exp_term.
2106 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2107 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2108 unsigned_eval_t instead of unsigned int. Change casts accordingly.

2124 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2126 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2127 stamp-h does not exist yet. This avoids running it a second time
2128 just after the initial ./configure.
2129 Reported by David MacKenzie and Tom McConnell.
2131 * m4.h: Replace the enum debug_info declaration with a series of
2132 #define's. The Ultrix 3.1 compiler would otherwise need casting
2133 (int) to most references, when used in expressions.
2134 Reported by Tom McConnell.
2136 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2138 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2139 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2140 calls the compiler. Previously, FP_PROTOTYPES was only calling
2141 the preprocessor; by not being subject to CFLAGS, this was
2142 discouraging those flags asking for ANSI compilation.
2143 * acconfig.h: Document HAVE_PROTOTYPES.
2144 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2145 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2146 Reported by Eric Backus.
2148 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2149 from the environment. Default CFLAGS to -g if not set.
2150 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2151 * lib/Makefile.in: Have CFLAGS substituted from configure.
2152 Reported by Eric Backus and Tom McConnell.
2154 * configure.in: m4_undefine changeword before using AC_ENABLE.
2156 * m4.h: Declare prototypes for error (for ANSI compilers only),
2157 prefix_all_builtins and reference_error.
2158 Reported by Tom McConnell.
2160 * input.c (set_word_regexp): Do not try to initialize the array
2161 test from a string, this does not work with non-ANSI compilers.
2162 Reported by Eric Backus.
2164 * Makefile.in (dist): Clean examples/ before saving it.
2165 (distclean-local): Also remove stamp-h.
2166 Reported by Eric Backus.
2168 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2170 Reported by Tom McConnell.

2177 * Makefile.in (DISTFILES): Distribute install.sh.
2178 * install.sh: New file, copied from elsewhere.

2183 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2184 * acconfig.h: Explain ENABLE_CHANGEWORD.
2186 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2187 from code provided by Pete Chown]
2188 * m4.h: Add original_text field to u_t variant of union u.
2189 Declare TOKEN_DATA_FUNC macro.
2190 * builtin.c: Declare changeword.
2191 (m4_changeword): New function.
2192 * input.c: Include "regex.h", define variables with word regexps.
2193 (input_init): Initialize the word regexp.
2194 (set_word_regexp): New.
2195 (next_token): Declare local variables, use the previous code if
2196 default_word_regexp is true. Else, match using a new code. Save
2198 * macro.c (expand_token): Ship out original text if not a macro
2200 Reported by Krste Asanovic and Pete Chown.
2202 [These modifs all depend upon ENABLE_CHANGEWORD]
2203 * m4.h: Declare external user_word_regexp.
2204 * m4.c: Declare user_word_regexp, and initialize it from
2205 --word-regexp or -W, or NULL if not specified.
2206 * input.c: Use user_word_regexp if specified, instead of
2207 DEFAULT_WORD_REGEXP.
2209 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2212 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2213 * checks/Makefile.in: Empty the suffix list.
2214 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.

2217 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2219 * m4.h: Declare nesting_limit as external.
2220 * macro.c (expand_macro): Stop execution whenever nesting limit
2222 Reported by Bengt Mertensson.
2224 * eval.c (evaluate): Diagnose excess characters in eval input.
2225 Things like `eval(08)' used to return 0 with no diagnostic.
2227 * m4.h: Capitalize first letter of all macro arguments in
2230 * m4.c: Declare warning_status, initialize it to 0. Add new
2231 option -E, or --fatal-warnings, which sets warning_status to
2232 EXIT_FAILURE instead.
2233 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2234 EXIT_FAILURE if not otherwise done by header files.
2235 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2236 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,

2242 * examples/include.m4: Include incl-test.m4 instead of
2244 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2246 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2248 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2249 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2250 also tested it on a Sun Sparc workstation running SunOS 4.x.
2252 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2253 49.format check, abusing a `union values' argument with sprintf
2254 without selecting the proper field. Now, save the formatting type
2255 first, delaying the fetch of the corresponding argument.
2256 Reported by Joseph E. Sacco and Tom Quinn.
2258 * format.c (format): Remove const from char *fmt declaration when
2259 not HAVE_EFGCVT, because a NUL may be forced into it.
2261 * m4.h: Declare atof() when not STDC_HEADERS.
2262 Reported by Joseph E. Sacco.
2264 * Regenerate configure using Autoconf 1.11, this corrects a
2265 problem about an incorrect cpp seting on NeXT 3.1.
2266 Reported by Alexander Lehmann.
2268 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2270 * m4.h (_): Change argument from `x' to `Args'.
2272 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)

2288 substitute ${U}stackovf.o for STACKOVF.
2289 * acconfig.h: Declare USE_STACKOVF.
2290 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2291 * m4.h: Declare setup_stackovf_trap().
2292 * m4.c: Call setup_stackovf_trap().
2293 * tests/stackovf_test.sh: New file.

2297 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2299 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2301 Sun Jan 30 14:24:19 1994 (pinard at icule)
2303 * m4.h: Remove definition of volatile, not used anymore.
2304 Reported by Jim Meyering and Joseph E. Sacco.
2306 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2307 of `if ... else /* nothing */' for if macros.
2308 Reported by Jim Meyering.
2310 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2311 warning from gcc about `repl' possibly used before defined.
2312 Reported by Jim Meyering.
2314 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2315 Reported by Jim Meyering.
2317 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2319 * m4.h: Move the conditional definition of volatile after the
2320 inclusion of system files, because they may define it first.
2322 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2324 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2325 get around a problem with Alpha make seeing a syntax error, there.
2326 Reported by Vern Paxson.
2328 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2330 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2331 Reported by Richard Stallman.
2333 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)

2341 * m4.c: Initialize show_help and show_version to zero.
2343 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2344 Use them in exit() and usage() calls.
2346 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2348 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2349 syserr() macro. Delete errref, add reference_error and M4ERROR.
2350 * m4.c: Replace errref, which was returning an input reference
2351 string, with reference_error, which prints it on standard error.
2352 * builtin.c, output.c: Use errno as second parameter to error,
2353 instead of using syserr() with %s.
2354 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2355 Doing so, the program name appears after the input reference
2356 instead of before, which eases M-x next-error processing.
2358 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2360 * checks/get-them: Escape braces with backslashes in patterns,
2361 because HPUX-9.01 awk needs this.

2370 Declare xrealloc, for use in errref().
2371 * m4.c: Delete error_message_prefix() function, add errref().
2372 * *.c: Use error() systematically in place of all error macros,
2373 now that error() flushes stdout first. Make needed adjustments.
2375 * m4.h: Remove const in sys_errlist[] declaration, it creates
2376 conflicts on SGI and Alpha.
2377 Reported by Kaveh R. Ghazi.
2379 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

2397 * input.c (input_init): Initialize quote and comment strings
2398 explicitely instead of calling set_quotes and set_comment: by
2399 doing so, we ensure we do not free uninitialized variables.
2401 * checks/check-them: Reverse arguments to both diff, so the
2402 expected is on the left and the obtained on the right.
2404 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2405 macros. Delete declarations for m4error, warning, fatal and
2406 internal_error, add declaration for error_message_prefix.
2407 * m4.c: Delete m4error, warning, fatal and internal_error
2408 routines, add error_message_prefix routine.
2409 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2410 warning with WARNING*, fatal with FATAL* and internal_error with
2412 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
2413 this is not needed anymore.
2415 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
2416 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
2417 and debug_message, add declaration for debug_message_prefix.

2419 Delete debug_print and debug_message routines, add
2420 debug_message_prefix routine.
2421 * builtin.c, debug.c: Replace debug_print routine calls with
2422 DEBUG_PRINT* macro calls.

2428 (trace_format): Use stdarg instead of varargs if __STDC__.
2430 * configure.in: Remove checks for vfprintf and _doprnt. These
2431 implementations use varargs tricks which are not portable enough.
2432 * lib/vfprintf.c: Deleted.
2433 * lib/_doprnt.c: Deleted.
2434 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
2435 Reported by Joel Sherrill.

2454 Reported by Joel Sherrill.
2456 * builtin.c (prefix_all_builtins): Instead of the table size, use
2457 the null entry at end for stopping the loop. It was overwritten.
2458 Reported by Andreas Schwab and Jim Meyering.
2460 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
2461 Reported by Kaveh R. Ghazi.

2648 Sat Feb 6 14:59:22 1993 Francois Pinard (pinard@icule)
2650 * Makefile.in, lib/Makefile.in, check/Makefile.in: In dist goals,
2651 ensure 777 mode for directories, so older tar's will restore file
2654 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
2656 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
2657 so the installer can override automatically configured choices.
2658 Reported by Karl Berry.
2660 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
2662 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The
2663 previous version was not working properly on m68k-hp-bsd4.3.
2664 Reported by Roland McGrath.
2666 * lib/_doprnt.c: Stolen from Oleo distribution.
2667 * configure.in: Check for _doprnt.c if vfprintf.c selected.
2668 * lib/Makefile.in: Distribute _doprnt.c.
2669 Do not distribute regex.[ch].old anymore.
2671 Fri Jan 1 19:42:23 1993 Francois Pinard (pinard at icule)
2673 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
2674 Richard wants it there.
2676 Sun Dec 27 07:01:54 1992 Francois Pinard (pinard at icule)
2678 * Makefile.in: Add DEFS to MDEFINES.
2679 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
2680 (libm4.a): Remove the library before creating it.
2681 (distclean): Remove tags and TAGS too.
2683 Wed Dec 23 12:46:55 1992 Francois Pinard (pinard at icule)
2685 * Makefile.in (dvi, m4.dvi): New goals.
2687 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
2688 macro.c, output.c, path.c, symtab.c: Change Copyright from
2689 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
2691 * examples/divert.m4: Deleted, this bug has been corrected.
2693 * Makefile.in (texclean, mostlyclean): New goals.
2695 * Makefile.in (clean): Remove clutter from ansi2knr.
2696 Reported by Pierre Gaumond.
2697 Reported by Greg A. Woods.
2699 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
2701 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
2702 might well use CFLAGS is s/he needs it.
2704 * Makefile.in: Allow installation of info files from a separate
2706 Reported by Jason Merrill.
2707 Reported by David MacKenzie.
2708 Reported by Skip Montanaro.
2709 Reported by Erez Zadok.
2710 Reported by Assar Westerlund.
2712 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
2715 This is still a beta release for the future GNU m4 version 1.1.
2717 * lib/alloca.c: New, from elsewhere.
2718 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2720 * m4.h: Do not define index/rindex if already defined. If
2721 FALSE/TRUE are already defined, do not redefine them, but merely
2722 define boolean typedef to int.
2724 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2725 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2726 because some C compilers do not like connectives with #ifdef.
2727 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2728 __GNUC__ and once for __STDC__.
2729 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2731 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2732 Makefile dependencies. Without it, make keeps destroying and
2733 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2735 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2736 to diversion/DIVERSION, this was a spelling error.
2738 * m4.c: Declare version[], remove #include "version.h".
2739 * version.h: Deleted.
2740 * Makefile.in: Remove references to version.h.
2742 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2743 production, by using a simpler and more robust algorithm. This
2744 solves the problem of synclines sometimes written in the middle of
2745 an output line. Delete sync_line() and output_lines variable.
2746 * m4.h: Remove sync_line prototype and output_lines declaration.
2747 * input.c (next_char), output.c (shipout_text): Remove references
2749 * input.c (push_file, pop_file): Merely put the value -1 in
2750 output_current_line instead of calling sync_line, for delaying a
2751 single `#line NUM FILE' before next output line. Do not test
2752 for sync_output, because this is unnecessary clutter.
2753 * output.c (make_divertion, insert_divertion): Idem.
2754 * input.c: Rename must_advance_line to start_of_input_line, for
2757 * debug.c (trace_header): Select a new debug line format, which
2758 better complies with GNU standards for formatting error messages.
2759 With option `-dfl', M-x next-error might be used on the output.
2760 * m4.c (vmesg): Adjust format of error output to GNU standards.
2761 * m4.texinfo: Adjust examples for `make check' to work.
2763 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2764 case for enum debug_info constants, which were all lower case.
2766 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2768 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2769 collected patches. I tried a few times using newer regex.[ch], it
2770 mysteriously stopped aborting with this one. Insecure feeling...
2771 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2773 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2775 * m4.c: Change `--no-warnings' to `--silent'.
2776 Reported by David MacKenzie.
2778 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2779 leave it off for now. See comment in m4.c for justification.
2780 Reported by David MacKenzie.
2782 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2783 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2785 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2787 * Makefile.in: Ensure recursive cleaning is done before local
2788 cleaning for all clean goals.
2790 * builtin.c (ntoa): Ensure the value is always interpreted as a
2791 signed quantity, whatever the radix is.
2793 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2795 * builtin.c, format.c, input.c: Split long lines.
2796 * m4.c: Use typedef macro_definition instead of struct
2798 * symtab.c: Use typedef symbol instead of struct symbol.
2800 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2802 * *.[ch]: Remove all trailing whitespace, in code and comments.
2804 * configure.in: Find some awk.
2805 * Makefile.in: Add $(AWK) to MDEFINES.
2806 * checks/Makefile.in: Transmit $(AWK) to get_them.
2807 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2808 awk script when switching files, because without this, mawk runs
2809 out of file descriptors.
2811 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2813 * Makefile.in (realclean): Delete m4.info*.
2814 Reported by Jim Meyering.
2816 * Makefile.in: Adjust and link with checks/Makefile.
2817 * checks/Makefile.in: New.
2818 * configure.in: Output checks/Makefile.
2820 * checks/get_them: Have the dnl header of each test more
2821 recognizable by next-error, also use a better message.
2823 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2825 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2826 And use that only if __GNUC__ since we're using it's GCC-specific
2827 semantics that tell the compiler the associated function doesn't
2830 * builtin.c (substitute): Don't use character as an array index.
2831 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2832 warnings with gcc -W -Wall on systems with qsort prototype.
2833 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2836 * eval.c (most functions): Add parentheses to assignments used
2837 as truth values go avoid warnings from gcc -Wall.
2839 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2840 any functions that don't need external scope.
2842 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2843 (many functions and arrays): Declare `const'.
2845 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2847 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2848 removing the declaration from m4.h. Also rename false to FALSE
2851 * lib/Makefile.in (Makefile): New goal.
2853 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2854 so heavily loaded. It gets more easily overridable, calling make.
2855 Reported by Jim Meyering.
2857 * Makefile.in (dist): Get .fname from the current directory name,
2858 instead of from version.h. I need updating many files manually,
2859 when the version changes, version.h is just one of them.
2861 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2863 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2864 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2865 Reported by Tom McConnell.
2867 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2869 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2870 39.cleardiv, which were describing missing or spurious newlines.
2871 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2872 do not depend on machine word size, `/bin/false' implementation,
2873 or `wc' output format. `make check' is more dependable, now.
2875 * checks/check_them: Summarize the failed tests by listing their
2876 name, at end. If none, issue `All checks successful'. Output
2877 `Checking' instead of `Input file:'.
2879 * checks/get_them, checks/check_them: Reindented.
2881 * Makefile.in (dist): chmod a+r before making the tar file.
2883 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2885 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2887 * input.c (next_token): Reinitialize token_buttom just after using
2888 it as a watermark with obstack_free. Or else, a future token, big
2889 enough for triggering reallocation of the obstack chunk, could
2890 void the initialized value of token_buttom, later causing panic in
2891 obstack_free. Rename token_buttom to token_bottom everywhere.
2893 * m4.h: Before declaring errno, first include <errno.h> and
2894 ensure that it does not define errno.
2895 Reported by Richard Stallman.
2897 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
2899 * builtin.c: Define and use DECLARE macro for builtins.
2901 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
2902 argument, this is a common idiom for introducing long comments.
2904 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
2905 arguments. The last argument was silently ignored.
2907 * m4.c (cmd_error): Add a missing semicolon before va_end().
2909 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
2911 * Makefile.in: Now handle protoized sources. Define and use U.
2912 Compile and use ansi2knr with old compilers. Update DISTFILES.
2913 Add `aclocal.m4' to `configure' dependencies.
2914 * ansi2knr.c: New, from Ghostscript distribution.
2915 * configure.in: Define U through FP_PROTOTYPES for old compilers.
2916 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
2917 * aclocal.m4: New, provide FP_PROTOTYPES.
2918 * m4.h: Conditionnaly protoized through Args, save for varags.
2919 * builtin.c: Protoized. Then:
2920 Include <sys/types.h> if size_t is not defined, before "regex.h".
2921 (m4_ifelse): Fetch built-in name properly for diagnostic.
2922 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
2923 (m4_regexp): Add const to `msg' declaration.
2924 (m4_patsubst): Add const to `msg' declaration.
2925 * debug.c: Protoized, save for varargs.
2926 * eval.c: Protoized.
2927 * format.c: Protoized.
2928 * input.c: Protoized.
2929 * m4.c: Protoized, save for varargs. Then:
2930 (xfree): Accept void * instead of char *.
2931 (xmalloc): Return void * instead of char *.
2932 (xrealloc): Accept and return void * instead of char *.
2933 * macro.c: Protoized.
2934 * output.c: Protoized.
2935 * path.c: Protoized. Then cast some (char *) over xmalloc's.
2936 * symtab.c: Protoized.
2938 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
2940 * m4.texinfo: Remove directory from diagnostics in 30.include,
2941 51.eval, 56.errprint and 57.m4exit tests.
2943 * m4.h: Remove declarations for int or void system functions, they
2944 cause more conflicting trouble than they make good.
2946 * configure.in: Avoid configuration header file. Add some tests.
2947 * m4.h: Remove #include "config.h".
2948 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
2949 Then, rewritten for better compliance with GNU standards.
2951 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
2953 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
2954 because of a misplaced #endif.
2956 * Many *.[hc] files: Correct intra-line spacing here and there,
2957 according to GNU indent 1.6 advice.
2959 * configure.in: New, using Autoconf 1.2.
2960 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.

2970 * version.h: De-automatize, force value in.
2972 * m4.c: Changes in order to use a newer getopt.h.
2973 Reported by David MacKenzie.
2975 * checks/: New name for examples/.
2976 * checks/get_them: New location for etc/get_examples.
2977 * checks/check_them: New location for etc/check_examples.

2985 * Makefile.in (check): Add m4 as dependency.
2987 * m4.c: Accept --no-warnings instead of --no_warnings, and
2988 --no-gnu-extensions instead of --no_gnu_extensions. Make the
2989 usage message more informative.

3006 Reported by Richard Stallman.
3008 * config/hmake-unicos, config/s-unicos.h: New files.
3009 Reported by Hal Peterson.
3011 * eval.c (exp_term): Have N^0 return 1.
3012 Reported by Michael Fetterman.
3014 * eval.c, input.c, m4.h: Remove last comma in enums.

3053 considerably. See the manual for details.
3055 * The -tMACRO option is added, marks MACRO for tracing as soon
3058 * Builtins are traced after renaming iff they were before.
