1213 Also, some of the files here were never updated from the previous

1235 (fetch): Get latest gendocs files.
1236 (web-manual): Rewritten to use gendoc for multiformat manuals.

1238 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1239 preserving, but case insensitive, so generating html docs per node
1240 clashes between Index.html, the node file, and index.html, the
1241 top-level of the document tree...
1242 (Index macro): ...so renamed to this. Changed all references.

1304 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1306 Modernise the configury a little to prevent spurious errors from
1307 Autoconf-2.59's autoreconf:

1310 * config-h.in: ...this to better support DOS 8.3 file systems.
1311 * acconfig.h: Removed.

1332 * src/output.c (mkstemp): Make non-static, and build regardless of

1336 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1338 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
1339 changes from your editor buffer first.
1341 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
1342 * src/m4.c: And include them as appropriate.

1373 portability bug reported by Marion Hakanson in
1374 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

1494 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1495 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1496 of $U, put underline in extensions rather than in basenames. Use
1497 implicit rules, now that regularity makes this possible.
1498 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1499 of ansi2knr whenever it is needed.
1500 * configure.in: Adjusted for correct STACKOVF substitution.
1501 * src/debug.c (trace_format): When not __STDC__, use (...) as a

1518 Reported by Jim Kingdon.
1520 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1522 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

1542 Reported by David MacKenzie.
1544 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)

1552 * src/stackovf.c: Declare the handler_t typedef earlier in the

1581 (realclean): Remove it.
1582 * Makefile.in: Make TAGS in lib also, not just in src.
1583 Reported by Karl Berry.
1585 * Makefile.in (distclean, realclean): Instead of recursively
1586 calling $(MAKE) for the -local part, allow parallel execution of
1587 -recursive and -local, only delay the removal of config.status,
1588 which is repeated in both goals.
1590 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
1594 * Makefile.in: Group all *clean-recursive goals in one, using sed

1600 Reported by Kaveh R. Ghazi.
1602 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1603 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1606 * configure.in: Use date instead of touch for stamp-h.
1607 * Makefile.in (stamp-h.in): Idem.
1609 * Makefile.in (distclean, realclean): Force serial execution of
1610 both goals, in case parallel makes are being used.

1663 * src/m4.h: Adjust declaration for prefix_all_buitins.
1664 * src/builtin.c (builtin_init): Merge in functionality from
1665 previous prefix_all_buitins function, while making entries in the
1666 symbol table, but not modifying the builtin description itself.
1668 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1669 because *many* compilers do not accept an empty `default:'.
1670 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1671 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1673 * configure.in: Use AC_TYPE_SIGNAL.

1692 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
1694 * Makefile.in: Adjusted.
1695 * configure.in: Configure new Makefiles.
1697 * m4.h: Declare STRING typedef. Use it for comment and quote
1698 strings, adjusting all references. (This is the rudiments of a
1699 beginning for the eventual withdrawal of NUL terminated strings.)
1700 * output.c (shipout_text): Accept a length parameter, and use it.
1701 All callers adjusted.
1703 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
1705 * m4.h: Include <unistd.h> if it exists.

1726 * m4.h: Declare freeze_diversions.
1727 * freeze.c: Document frozen file format, revise it, call
1728 freeze_diversions to add diversions to frozen format, and code to
1729 reload them properly.
1730 * m4.c: Do not undivert automatically at end when status being
1731 frozen. Do not call builtin_init when reloading frozen state.
1733 Speed up diversion processing:
1734 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
1735 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
1736 structure and variables, cached variables out of output_diversion,
1737 reallocate_diversion_for and OUTPUT_CHARACTER.
1738 (shipout_text, make_diversion, insert_diversion): Adapted to new

1751 constant HASHMAX, for -H option to work better.
1753 * builtin.c (DECLARE): Simplify by using _ ().
1755 * freeze.c: New file.
1756 * Makefile.in: Compile it, distribute it.
1757 * m4.c: Recognize, document and process --freeze-state (-F) and

1759 only if no reloading some state.
1760 * builtin.c (define_builtin): Remove static specifier.
1761 (find_builtin_by_name): Remove static specifier.

1781 * m4.h: Include <sys/types.h>.
1782 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
1783 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
1785 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
1787 * builtin.c (dump_args): Declare len as size_t, not int.
1789 * debug.c: Prototype the forward declaration of debug_set_file.
1791 * builtin.c (m4_undivert): Replace div by file, for avoiding the
1792 shadowing of this variable.

1805 * m4.c (usage): Reorganize the --help output by topic. Include a
1806 description for debugging flags.
1808 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
1810 * configure.in: If sigaction is available and SA_ONSTACK defined,
1811 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
1812 defined, use sigvec. Else don't compile stackovf.c.
1813 * stackovf.c (setup_stackovf_trap): Idem.
1814 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
1817 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
1819 * m4.c (usage): Replace printf par fputs.
1821 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
1825 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
1827 * configure.in: Check for sigaction and sigvec. Add a new delayed
1828 check for RLIMIT_STACK, combine in the checking for getrlimit.
1829 All those things are not universally available.
1830 * stackovf.c: Split setting up the trap handler and catching
1831 signals, for better taking care of various configure outcomes.
1832 * examples/stackovf.sh: Correct a typo.
1833 Reported by Eric Backus, Jim Avera and Jim Meyering.
1835 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
1837 * ansi2knr.c: New version sent by its author, Peter Deutsch.
1839 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
1841 * Makefile.in: Modify so parallel make will not try making
1842 lib/libm4.a twice simultaneously.
1843 Reported by Jim Meyering.
1845 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
1847 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
1848 error message, for when no code possibility exists. Even if this
1849 line is completely #ifdef'ed out, it brings a syntax error.
1850 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
1852 * Makefile.in (install): Have install depend on all too, for lib
1853 to be remade as needed.
1855 * examples/stackovf.sh: Try ksh, bsh and bash for shells
1856 providing ulimit, instead of using only ksh.
1857 Reported by Jim Avera and Joseph E. Sacco.
1859 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
1861 * Makefile.in (check): Have it depend on all instead of m4. In
1862 this way, a change in lib will be detected and processed.
1864 * builtin.c (numeric_arg): Use strtol and verify the conversion,
1865 instead of using sscanf which stops as soon as there is a
1866 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
1867 and divert(1xyzzy) were all accepted without any warning or error
1869 * m4.h: Declare strtol as long if not including stdlib.h.
1870 * configure.in: Check for limits.h, and replace strtol if missing.
1871 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
1872 * lib/strtol.c: New file, from elsewhere.
1873 Reported by Andreas Schwab.
1875 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
1877 * macro.c (expand_macro): Cast value to (boolean) prior to
1878 assigning it to traced.
1879 Reported by Tom McConnell.
1881 * Makefile.in (m4): Always make all in lib first.
1882 Reported by Jim Meyering.
1884 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
1886 * stackovf.c: Isolated OS-dependent sections; Improved portability,
1887 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
1888 handlers), and a default error message if the fault address is not
1889 available (when neither siginfo.h nor BSD sigcontext are supported).
1890 * configure.in: Changes for stackovf.h: Check for sigcontext,
1891 sigaction, sigstack, and define rlim_t as int if necessary.
1892 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
1893 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
1894 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
1896 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
1898 * configure.in: Use AC_SET_MAKE.
1899 * Makefile.in: Use @SET_MAKE@.
1900 Reported by Jim Meyering.
1902 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
1903 Reported by Ian Taylor.
1905 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
1907 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
1908 because siginfo.h is unrelated to standard headers, and siginfo.h
1909 is already checked for.
1910 Reported by Joseph E. Sacco.
1912 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
1914 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
1917 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
1919 * builtin.c (substitute): Use \& to represent this part of the
1920 string which was matched by the whole regexp, instead of
1921 representing the whole string. Any usage of \0 issues a warning
1922 and acts like \&, it will disappear in some subsequent release.
1924 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
1926 * m4.c: Complete prototype for forwarded declaration of usage.
1928 * input.c (init_macro_token): Correct own reference in error
1929 message. Previous name get_macro_func was referred to instead.
1930 (next_char): Correct own reference in error message. Previous
1931 name advance_input was referred to instead.
1933 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
1934 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
1935 and_term, not_term, logical_not_term, cmp_term, shift_term,
1936 add_term, mult_term, exp_term, unary_term, simple_term): Add
1937 prototype to forwarded declarations. Declare parameter v1 as
1938 eval_t * instead of int *. Same for local variable v2 in dyadic
1939 functions. Same for result in exp_term.
1940 * builtin.c (m4_eval): Declare value as eval_t instead of int.
1941 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
1942 unsigned_eval_t instead of unsigned int. Change casts accordingly.
1943 (shipout_int): Cast first argument of ntoa to eval_t.
1944 Reported by Thorsten Ohl.
1946 * macro.c: Complete the prototypes of forwarded expand_macro and
1948 Reported by Thorsten Ohl.
1950 * m4.h: Define voidstar as void * or char * depending on __STDC__.
1951 The Ultrix 3.1 compiler cannot do much with void pointers.
1953 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
1954 * m4.c (xfree): Replace void * by voidstar.
1955 Reported by Tom McConnell.
1957 * ansi2knr.1: New, from elsewhere.
1958 * Makefile.in (DISTFILES): Distribute ansi2knr.1
1960 * Makefile.in (stamp-h.in): Avoid running ./config.status if
1961 stamp-h does not exist yet. This avoids running it a second time
1962 just after the initial ./configure.
1963 Reported by David MacKenzie and Tom McConnell.
1965 * m4.h: Replace the enum debug_info declaration with a series of
1966 #define's. The Ultrix 3.1 compiler would otherwise need casting
1967 (int) to most references, when used in expressions.
1968 Reported by Tom McConnell.
1970 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
1972 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
1973 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
1974 calls the compiler. Previously, FP_PROTOTYPES was only calling
1975 the preprocessor; by not being subject to CFLAGS, this was
1976 discouraging those flags asking for ANSI compilation.
1977 * acconfig.h: Document HAVE_PROTOTYPES.
1978 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
1979 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
1980 Reported by Eric Backus.
1982 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
1983 from the environment. Default CFLAGS to -g if not set.
1984 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
1985 * lib/Makefile.in: Have CFLAGS substituted from configure.
1986 Reported by Eric Backus and Tom McConnell.
1988 * configure.in: m4_undefine changeword before using AC_ENABLE.
1990 * m4.h: Declare prototypes for error (for ANSI compilers only),
1991 prefix_all_builtins and reference_error.
1992 Reported by Tom McConnell.
1994 * input.c (set_word_regexp): Do not try to initialize the array
1995 test from a string, this does not work with non-ANSI compilers.
1996 Reported by Eric Backus.
1998 * Makefile.in (dist): Clean examples/ before saving it.
1999 (distclean-local): Also remove stamp-h.
2000 Reported by Eric Backus.
2002 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2004 Reported by Tom McConnell.
2006 * checks/Makefile.in (clean): Depends on mostlyclean.
2007 (mostlyclean): New goal.
2009 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2011 * Makefile.in (DISTFILES): Distribute install.sh.
2012 * install.sh: New file, copied from elsewhere.
2013 Reported by Assar Westerlund and Kaveh R. Ghazi.
2015 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2017 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2018 * acconfig.h: Explain ENABLE_CHANGEWORD.
2020 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2021 from code provided by Pete Chown]
2022 * m4.h: Add original_text field to u_t variant of union u.
2023 Declare TOKEN_DATA_FUNC macro.
2024 * builtin.c: Declare changeword.
2025 (m4_changeword): New function.
2026 * input.c: Include "regex.h", define variables with word regexps.
2027 (input_init): Initialize the word regexp.
2028 (set_word_regexp): New.
2029 (next_token): Declare local variables, use the previous code if
2030 default_word_regexp is true. Else, match using a new code. Save
2032 * macro.c (expand_token): Ship out original text if not a macro
2034 Reported by Krste Asanovic and Pete Chown.
2036 [These modifs all depend upon ENABLE_CHANGEWORD]
2037 * m4.h: Declare external user_word_regexp.
2038 * m4.c: Declare user_word_regexp, and initialize it from
2039 --word-regexp or -W, or NULL if not specified.
2040 * input.c: Use user_word_regexp if specified, instead of
2041 DEFAULT_WORD_REGEXP.
2043 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2046 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2047 * checks/Makefile.in: Empty the suffix list.
2048 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2050 * m4.c: Declare nesting_limit and initialize it to 250.
2051 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2053 * m4.h: Declare nesting_limit as external.
2054 * macro.c (expand_macro): Stop execution whenever nesting limit
2056 Reported by Bengt Mertensson.
2058 * eval.c (evaluate): Diagnose excess characters in eval input.
2059 Things like `eval(08)' used to return 0 with no diagnostic.
2061 * m4.h: Capitalize first letter of all macro arguments in
2064 * m4.c: Declare warning_status, initialize it to 0. Add new
2065 option -E, or --fatal-warnings, which sets warning_status to
2066 EXIT_FAILURE instead.
2067 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2068 EXIT_FAILURE if not otherwise done by header files.
2069 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2070 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2071 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2072 argument of all M4ERROR calls.
2073 Reported by Noah Friedman.
2075 * examples/incl-test.m4: Renamed from incl_test.m4.
2076 * examples/include.m4: Include incl-test.m4 instead of
2078 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2080 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2082 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2083 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2084 also tested it on a Sun Sparc workstation running SunOS 4.x.
2086 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2087 49.format check, abusing a `union values' argument with sprintf
2088 without selecting the proper field. Now, save the formatting type
2089 first, delaying the fetch of the corresponding argument.
2090 Reported by Joseph E. Sacco and Tom Quinn.
2092 * format.c (format): Remove const from char *fmt declaration when
2093 not HAVE_EFGCVT, because a NUL may be forced into it.
2095 * m4.h: Declare atof() when not STDC_HEADERS.
2096 Reported by Joseph E. Sacco.
2098 * Regenerate configure using Autoconf 1.11, this corrects a
2099 problem about an incorrect cpp seting on NeXT 3.1.
2100 Reported by Alexander Lehmann.
2102 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2104 * m4.h (_): Change argument from `x' to `Args'.
2106 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2108 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2109 bringing more evil than good on a few systems.

2119 * stackovf.c: New file implementing stack-overflow detection.
2120 * configure.in: Check for getrlimit, sigaction. If all of
2121 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2122 substitute ${U}stackovf.o for STACKOVF.

2141 of `if ... else /* nothing */' for if macros.
2142 Reported by Jim Meyering.
2144 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2145 warning from gcc about `repl' possibly used before defined.
2146 Reported by Jim Meyering.
2148 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2149 Reported by Jim Meyering.
2151 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2153 * m4.h: Move the conditional definition of volatile after the
2154 inclusion of system files, because they may define it first.
2156 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2158 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2159 get around a problem with Alpha make seeing a syntax error, there.

2178 Use them in exit() and usage() calls.
2180 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2182 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2183 syserr() macro. Delete errref, add reference_error and M4ERROR.
2184 * m4.c: Replace errref, which was returning an input reference
2185 string, with reference_error, which prints it on standard error.
2186 * builtin.c, output.c: Use errno as second parameter to error,
2187 instead of using syserr() with %s.
2188 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2189 Doing so, the program name appears after the input reference
2190 instead of before, which eases M-x next-error processing.
2192 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2194 * checks/get-them: Escape braces with backslashes in patterns,

2204 Declare xrealloc, for use in errref().
2205 * m4.c: Delete error_message_prefix() function, add errref().
2206 * *.c: Use error() systematically in place of all error macros,
2207 now that error() flushes stdout first. Make needed adjustments.
2209 * m4.h: Remove const in sys_errlist[] declaration, it creates
2210 conflicts on SGI and Alpha.
2211 Reported by Kaveh R. Ghazi.
2213 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

2229 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2231 * input.c (input_init): Initialize quote and comment strings
2232 explicitely instead of calling set_quotes and set_comment: by
2233 doing so, we ensure we do not free uninitialized variables.
2235 * checks/check-them: Reverse arguments to both diff, so the
2236 expected is on the left and the obtained on the right.
2238 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2239 macros. Delete declarations for m4error, warning, fatal and
2240 internal_error, add declaration for error_message_prefix.
2241 * m4.c: Delete m4error, warning, fatal and internal_error
2242 routines, add error_message_prefix routine.
2243 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2244 warning with WARNING*, fatal with FATAL* and internal_error with
2246 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
2247 this is not needed anymore.
2249 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
2250 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
2251 and debug_message, add declaration for debug_message_prefix.

2254 debug_message_prefix routine.
2255 * builtin.c, debug.c: Replace debug_print routine calls with

2262 (trace_format): Use stdarg instead of varargs if __STDC__.
2264 * configure.in: Remove checks for vfprintf and _doprnt. These
2265 implementations use varargs tricks which are not portable enough.
2266 * lib/vfprintf.c: Deleted.
2267 * lib/_doprnt.c: Deleted.
2268 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
2269 Reported by Joel Sherrill.

2287 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
2288 Reported by Joel Sherrill.
2290 * builtin.c (prefix_all_builtins): Instead of the table size, use
2291 the null entry at end for stopping the loop. It was overwritten.
2292 Reported by Andreas Schwab and Jim Meyering.
2294 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
2295 Reported by Kaveh R. Ghazi.

2551 * lib/alloca.c: New, from elsewhere.
2552 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2554 * m4.h: Do not define index/rindex if already defined. If
2555 FALSE/TRUE are already defined, do not redefine them, but merely
2556 define boolean typedef to int.
2558 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2559 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2560 because some C compilers do not like connectives with #ifdef.
2561 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2562 __GNUC__ and once for __STDC__.
2563 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2565 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2566 Makefile dependencies. Without it, make keeps destroying and
2567 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2569 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2570 to diversion/DIVERSION, this was a spelling error.
2572 * m4.c: Declare version[], remove #include "version.h".
2573 * version.h: Deleted.
2574 * Makefile.in: Remove references to version.h.
2576 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2577 production, by using a simpler and more robust algorithm. This
2578 solves the problem of synclines sometimes written in the middle of
2579 an output line. Delete sync_line() and output_lines variable.
2580 * m4.h: Remove sync_line prototype and output_lines declaration.
2581 * input.c (next_char), output.c (shipout_text): Remove references
2583 * input.c (push_file, pop_file): Merely put the value -1 in
2584 output_current_line instead of calling sync_line, for delaying a
2585 single `#line NUM FILE' before next output line. Do not test
2586 for sync_output, because this is unnecessary clutter.
2587 * output.c (make_divertion, insert_divertion): Idem.
2588 * input.c: Rename must_advance_line to start_of_input_line, for
2591 * debug.c (trace_header): Select a new debug line format, which
2592 better complies with GNU standards for formatting error messages.
2593 With option `-dfl', M-x next-error might be used on the output.
2594 * m4.c (vmesg): Adjust format of error output to GNU standards.
2595 * m4.texinfo: Adjust examples for `make check' to work.
2597 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2598 case for enum debug_info constants, which were all lower case.
2600 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2602 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2603 collected patches. I tried a few times using newer regex.[ch], it
2604 mysteriously stopped aborting with this one. Insecure feeling...
2605 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2607 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2609 * m4.c: Change `--no-warnings' to `--silent'.
2610 Reported by David MacKenzie.
2612 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2613 leave it off for now. See comment in m4.c for justification.
2614 Reported by David MacKenzie.
2616 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2617 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2619 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2621 * Makefile.in: Ensure recursive cleaning is done before local
2622 cleaning for all clean goals.
2624 * builtin.c (ntoa): Ensure the value is always interpreted as a
2625 signed quantity, whatever the radix is.
2627 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2629 * builtin.c, format.c, input.c: Split long lines.
2630 * m4.c: Use typedef macro_definition instead of struct
2632 * symtab.c: Use typedef symbol instead of struct symbol.
2634 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2636 * *.[ch]: Remove all trailing whitespace, in code and comments.
2638 * configure.in: Find some awk.
2639 * Makefile.in: Add $(AWK) to MDEFINES.
2640 * checks/Makefile.in: Transmit $(AWK) to get_them.
2641 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2642 awk script when switching files, because without this, mawk runs
2643 out of file descriptors.
2645 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2647 * Makefile.in (realclean): Delete m4.info*.
2648 Reported by Jim Meyering.
2650 * Makefile.in: Adjust and link with checks/Makefile.
2651 * checks/Makefile.in: New.
2652 * configure.in: Output checks/Makefile.
2654 * checks/get_them: Have the dnl header of each test more
2655 recognizable by next-error, also use a better message.
2657 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2659 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2660 And use that only if __GNUC__ since we're using it's GCC-specific
2661 semantics that tell the compiler the associated function doesn't
2664 * builtin.c (substitute): Don't use character as an array index.
2665 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2666 warnings with gcc -W -Wall on systems with qsort prototype.
2667 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2670 * eval.c (most functions): Add parentheses to assignments used
2671 as truth values go avoid warnings from gcc -Wall.
2673 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2674 any functions that don't need external scope.
2676 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2677 (many functions and arrays): Declare `const'.
2679 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2681 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2682 removing the declaration from m4.h. Also rename false to FALSE
2685 * lib/Makefile.in (Makefile): New goal.
2687 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2688 so heavily loaded. It gets more easily overridable, calling make.
2689 Reported by Jim Meyering.
2691 * Makefile.in (dist): Get .fname from the current directory name,
2692 instead of from version.h. I need updating many files manually,
2693 when the version changes, version.h is just one of them.
2695 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2697 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2698 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2699 Reported by Tom McConnell.
2701 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2703 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2704 39.cleardiv, which were describing missing or spurious newlines.
2705 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2706 do not depend on machine word size, `/bin/false' implementation,
2707 or `wc' output format. `make check' is more dependable, now.
2709 * checks/check_them: Summarize the failed tests by listing their
2710 name, at end. If none, issue `All checks successful'. Output
2711 `Checking' instead of `Input file:'.
2713 * checks/get_them, checks/check_them: Reindented.
2715 * Makefile.in (dist): chmod a+r before making the tar file.
2717 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2719 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2721 * input.c (next_token): Reinitialize token_buttom just after using
2722 it as a watermark with obstack_free. Or else, a future token, big
2723 enough for triggering reallocation of the obstack chunk, could
2724 void the initialized value of token_buttom, later causing panic in
2725 obstack_free. Rename token_buttom to token_bottom everywhere.
2727 * m4.h: Before declaring errno, first include <errno.h> and
2728 ensure that it does not define errno.
2729 Reported by Richard Stallman.
2731 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
2733 * builtin.c: Define and use DECLARE macro for builtins.
2735 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
2736 argument, this is a common idiom for introducing long comments.
2738 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
2739 arguments. The last argument was silently ignored.
2741 * m4.c (cmd_error): Add a missing semicolon before va_end().
2743 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
2745 * Makefile.in: Now handle protoized sources. Define and use U.
2746 Compile and use ansi2knr with old compilers. Update DISTFILES.
2747 Add `aclocal.m4' to `configure' dependencies.
2748 * ansi2knr.c: New, from Ghostscript distribution.
2749 * configure.in: Define U through FP_PROTOTYPES for old compilers.
2750 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
2751 * aclocal.m4: New, provide FP_PROTOTYPES.
2752 * m4.h: Conditionnaly protoized through Args, save for varags.
2753 * builtin.c: Protoized. Then:
2754 Include <sys/types.h> if size_t is not defined, before "regex.h".
2755 (m4_ifelse): Fetch built-in name properly for diagnostic.
2756 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
2757 (m4_regexp): Add const to `msg' declaration.
2758 (m4_patsubst): Add const to `msg' declaration.
2759 * debug.c: Protoized, save for varargs.
2760 * eval.c: Protoized.
2761 * format.c: Protoized.
2762 * input.c: Protoized.
2763 * m4.c: Protoized, save for varargs. Then:
2764 (xfree): Accept void * instead of char *.
2765 (xmalloc): Return void * instead of char *.
2766 (xrealloc): Accept and return void * instead of char *.
2767 * macro.c: Protoized.
2768 * output.c: Protoized.
2769 * path.c: Protoized. Then cast some (char *) over xmalloc's.
2770 * symtab.c: Protoized.
2772 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
2774 * m4.texinfo: Remove directory from diagnostics in 30.include,
2775 51.eval, 56.errprint and 57.m4exit tests.
2777 * m4.h: Remove declarations for int or void system functions, they
2778 cause more conflicting trouble than they make good.
2780 * configure.in: Avoid configuration header file. Add some tests.
2781 * m4.h: Remove #include "config.h".
2782 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
2783 Then, rewritten for better compliance with GNU standards.
2785 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
2787 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
2788 because of a misplaced #endif.
2790 * Many *.[hc] files: Correct intra-line spacing here and there,
2791 according to GNU indent 1.6 advice.
2793 * configure.in: New, using Autoconf 1.2.
2794 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
2795 * Delete old configure.in, configure, etc/configure.in,
2796 etc/configure, lib/configure.in, lib/configure and config/*.
2797 Reported by Jason Merrill.

2803 etc/nextvers.sh. Release numbers will be edited `by hand'.
2804 * version.h: De-automatize, force value in.
2806 * m4.c: Changes in order to use a newer getopt.h.
2807 Reported by David MacKenzie.
2809 * checks/: New name for examples/.
2810 * checks/get_them: New location for etc/get_examples.
