1199 (web-manual): Rewritten to use gendoc for multiformat manuals.

1201 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1202 preserving, but case insensitive, so generating html docs per node
1203 clashes between Index.html, the node file, and index.html, the
1204 top-level of the document tree...
1205 (Index macro): ...so renamed to this. Changed all references.

1267 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1269 Modernise the configury a little to prevent spurious errors from
1270 Autoconf-2.59's autoreconf:

1295 * src/output.c (mkstemp): Make non-static, and build regardless of

1299 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1301 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
1302 changes from your editor buffer first.
1304 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.

1335 value simply because fread returns zero. This fixes a
1336 portability bug reported by Marion Hakanson in
1337 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

1457 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1458 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1459 of $U, put underline in extensions rather than in basenames. Use
1460 implicit rules, now that regularity makes this possible.
1461 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1462 of ansi2knr whenever it is needed.
1463 * configure.in: Adjusted for correct STACKOVF substitution.
1464 * src/debug.c (trace_format): When not __STDC__, use (...) as a

1481 Reported by Jim Kingdon.
1483 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1485 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

1548 * Makefile.in (distclean, realclean): Instead of recursively
1549 calling $(MAKE) for the -local part, allow parallel execution of

1557 * Makefile.in: Group all *clean-recursive goals in one, using sed

1563 Reported by Kaveh R. Ghazi.

1569 * configure.in: Use date instead of touch for stamp-h.
1570 * Makefile.in (stamp-h.in): Idem.
1572 * Makefile.in (distclean, realclean): Force serial execution of

1625 calling a function by that name. Declare the variable.
1626 * src/m4.h: Adjust declaration for prefix_all_buitins.
1627 * src/builtin.c (builtin_init): Merge in functionality from
1628 previous prefix_all_buitins function, while making entries in the
1629 symbol table, but not modifying the builtin description itself.
1631 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1632 because *many* compilers do not accept an empty `default:'.
1633 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1634 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.

1642 * Makefile.in (check): Don't.
1643 Reported by Akiko Matsushita and Jim Meyering.
1645 * src/output.c (make_room_for, output_character_helper): New
1646 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
1647 a per buffer MAXIMUM_BUFFER_SIZE.
1649 * src/output.c (output_text): New function, for optimizing the
1650 output of strings of characters. Use it.

1657 * Makefile.in: Adjusted.
1658 * configure.in: Configure new Makefiles.
1660 * m4.h: Declare STRING typedef. Use it for comment and quote
1661 strings, adjusting all references. (This is the rudiments of a
1662 beginning for the eventual withdrawal of NUL terminated strings.)
1663 * output.c (shipout_text): Accept a length parameter, and use it.
1664 All callers adjusted.
1666 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
1668 * m4.h: Include <unistd.h> if it exists.

1685 Reported by David MacKenzie.
1688 * output.c (freeze_diversions): New function.
1689 * m4.h: Declare freeze_diversions.
1690 * freeze.c: Document frozen file format, revise it, call
1691 freeze_diversions to add diversions to frozen format, and code to
1692 reload them properly.
1693 * m4.c: Do not undivert automatically at end when status being
1694 frozen. Do not call builtin_init when reloading frozen state.
1696 Speed up diversion processing:
1697 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
1698 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
1699 structure and variables, cached variables out of output_diversion,
1700 reallocate_diversion_for and OUTPUT_CHARACTER.
1701 (shipout_text, make_diversion, insert_diversion): Adapted to new

1708 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
1709 dist works from another build directory.
1711 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
1713 * symtab.c (hack_all_symbols): Use hash_table_size instead of
1714 constant HASHMAX, for -H option to work better.
1716 * builtin.c (DECLARE): Simplify by using _ ().
1718 * freeze.c: New file.
1719 * Makefile.in: Compile it, distribute it.
1720 * m4.c: Recognize, document and process --freeze-state (-F) and
1721 --reload-state (-R) options. Pass a true flag to builtin_init
1722 only if no reloading some state.
1723 * builtin.c (define_builtin): Remove static specifier.
1724 (find_builtin_by_name): Remove static specifier.
1725 (builtin_init): Accept and obey a flag argument.

1740 Reported by Akiko Matsushita.
1742 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
1744 * m4.h: Include <sys/types.h>.
1745 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
1746 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
1748 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
1750 * builtin.c (dump_args): Declare len as size_t, not int.
1752 * debug.c: Prototype the forward declaration of debug_set_file.
1754 * builtin.c (m4_undivert): Replace div by file, for avoiding the
1755 shadowing of this variable.
1756 * output.c (insert_diversion): Idem.
1758 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
1759 (input_init): Duplicate default quote and comment strings.
1760 (set_quotes): Free previous quote strings in all cases. Duplicate
1761 even default quote strings.
1762 (set_comment): Free previous comment strings in all cases.

1768 * m4.c (usage): Reorganize the --help output by topic. Include a
1769 description for debugging flags.
1771 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
1773 * configure.in: If sigaction is available and SA_ONSTACK defined,
1774 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
1775 defined, use sigvec. Else don't compile stackovf.c.
1776 * stackovf.c (setup_stackovf_trap): Idem.
1777 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
1780 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
1782 * m4.c (usage): Replace printf par fputs.
1784 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
1788 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
1790 * configure.in: Check for sigaction and sigvec. Add a new delayed
1791 check for RLIMIT_STACK, combine in the checking for getrlimit.
1792 All those things are not universally available.
1793 * stackovf.c: Split setting up the trap handler and catching
1794 signals, for better taking care of various configure outcomes.
1795 * examples/stackovf.sh: Correct a typo.
1796 Reported by Eric Backus, Jim Avera and Jim Meyering.
1798 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
1800 * ansi2knr.c: New version sent by its author, Peter Deutsch.
1802 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
1804 * Makefile.in: Modify so parallel make will not try making
1805 lib/libm4.a twice simultaneously.
1806 Reported by Jim Meyering.
1808 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
1810 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
1811 error message, for when no code possibility exists. Even if this
1812 line is completely #ifdef'ed out, it brings a syntax error.
1813 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
1815 * Makefile.in (install): Have install depend on all too, for lib
1816 to be remade as needed.
1818 * examples/stackovf.sh: Try ksh, bsh and bash for shells
1819 providing ulimit, instead of using only ksh.
1820 Reported by Jim Avera and Joseph E. Sacco.
1822 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
1824 * Makefile.in (check): Have it depend on all instead of m4. In
1825 this way, a change in lib will be detected and processed.
1827 * builtin.c (numeric_arg): Use strtol and verify the conversion,
1828 instead of using sscanf which stops as soon as there is a
1829 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
1830 and divert(1xyzzy) were all accepted without any warning or error
1832 * m4.h: Declare strtol as long if not including stdlib.h.
1833 * configure.in: Check for limits.h, and replace strtol if missing.
1834 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
1835 * lib/strtol.c: New file, from elsewhere.
1836 Reported by Andreas Schwab.
1838 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
1840 * macro.c (expand_macro): Cast value to (boolean) prior to
1841 assigning it to traced.
1842 Reported by Tom McConnell.
1844 * Makefile.in (m4): Always make all in lib first.
1845 Reported by Jim Meyering.
1847 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
1849 * stackovf.c: Isolated OS-dependent sections; Improved portability,
1850 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
1851 handlers), and a default error message if the fault address is not
1852 available (when neither siginfo.h nor BSD sigcontext are supported).
1853 * configure.in: Changes for stackovf.h: Check for sigcontext,
1854 sigaction, sigstack, and define rlim_t as int if necessary.
1855 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
1856 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
1857 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
1859 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
1861 * configure.in: Use AC_SET_MAKE.
1862 * Makefile.in: Use @SET_MAKE@.
1863 Reported by Jim Meyering.
1865 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
1866 Reported by Ian Taylor.
1868 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
1870 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
1871 because siginfo.h is unrelated to standard headers, and siginfo.h
1872 is already checked for.
1873 Reported by Joseph E. Sacco.
1875 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
1877 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
1880 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
1882 * builtin.c (substitute): Use \& to represent this part of the
1883 string which was matched by the whole regexp, instead of
1884 representing the whole string. Any usage of \0 issues a warning
1885 and acts like \&, it will disappear in some subsequent release.
1887 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
1889 * m4.c: Complete prototype for forwarded declaration of usage.
1891 * input.c (init_macro_token): Correct own reference in error
1892 message. Previous name get_macro_func was referred to instead.
1893 (next_char): Correct own reference in error message. Previous
1894 name advance_input was referred to instead.
1896 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
1897 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
1898 and_term, not_term, logical_not_term, cmp_term, shift_term,
1899 add_term, mult_term, exp_term, unary_term, simple_term): Add
1900 prototype to forwarded declarations. Declare parameter v1 as
1901 eval_t * instead of int *. Same for local variable v2 in dyadic
1902 functions. Same for result in exp_term.
1903 * builtin.c (m4_eval): Declare value as eval_t instead of int.
1904 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
1905 unsigned_eval_t instead of unsigned int. Change casts accordingly.
1906 (shipout_int): Cast first argument of ntoa to eval_t.
1907 Reported by Thorsten Ohl.
1909 * macro.c: Complete the prototypes of forwarded expand_macro and
1911 Reported by Thorsten Ohl.
1913 * m4.h: Define voidstar as void * or char * depending on __STDC__.
1914 The Ultrix 3.1 compiler cannot do much with void pointers.
1916 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
1917 * m4.c (xfree): Replace void * by voidstar.
1918 Reported by Tom McConnell.
1920 * ansi2knr.1: New, from elsewhere.
1921 * Makefile.in (DISTFILES): Distribute ansi2knr.1
1923 * Makefile.in (stamp-h.in): Avoid running ./config.status if
1924 stamp-h does not exist yet. This avoids running it a second time
1925 just after the initial ./configure.
1926 Reported by David MacKenzie and Tom McConnell.
1928 * m4.h: Replace the enum debug_info declaration with a series of
1929 #define's. The Ultrix 3.1 compiler would otherwise need casting
1930 (int) to most references, when used in expressions.
1931 Reported by Tom McConnell.
1933 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
1935 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
1936 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
1937 calls the compiler. Previously, FP_PROTOTYPES was only calling
1938 the preprocessor; by not being subject to CFLAGS, this was
1939 discouraging those flags asking for ANSI compilation.
1940 * acconfig.h: Document HAVE_PROTOTYPES.
1941 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
1942 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
1943 Reported by Eric Backus.
1945 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
1946 from the environment. Default CFLAGS to -g if not set.
1947 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
1948 * lib/Makefile.in: Have CFLAGS substituted from configure.
1949 Reported by Eric Backus and Tom McConnell.
1951 * configure.in: m4_undefine changeword before using AC_ENABLE.
1953 * m4.h: Declare prototypes for error (for ANSI compilers only),
1954 prefix_all_builtins and reference_error.
1955 Reported by Tom McConnell.
1957 * input.c (set_word_regexp): Do not try to initialize the array
1958 test from a string, this does not work with non-ANSI compilers.
1959 Reported by Eric Backus.
1961 * Makefile.in (dist): Clean examples/ before saving it.
1962 (distclean-local): Also remove stamp-h.
1963 Reported by Eric Backus.
1965 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
1967 Reported by Tom McConnell.
1969 * checks/Makefile.in (clean): Depends on mostlyclean.
1970 (mostlyclean): New goal.
1972 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
1974 * Makefile.in (DISTFILES): Distribute install.sh.
1975 * install.sh: New file, copied from elsewhere.
1976 Reported by Assar Westerlund and Kaveh R. Ghazi.
1978 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
1980 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
1981 * acconfig.h: Explain ENABLE_CHANGEWORD.
1983 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
1984 from code provided by Pete Chown]
1985 * m4.h: Add original_text field to u_t variant of union u.
1986 Declare TOKEN_DATA_FUNC macro.
1987 * builtin.c: Declare changeword.
1988 (m4_changeword): New function.
1989 * input.c: Include "regex.h", define variables with word regexps.
1990 (input_init): Initialize the word regexp.
1991 (set_word_regexp): New.
1992 (next_token): Declare local variables, use the previous code if
1993 default_word_regexp is true. Else, match using a new code. Save
1995 * macro.c (expand_token): Ship out original text if not a macro
1997 Reported by Krste Asanovic and Pete Chown.
1999 [These modifs all depend upon ENABLE_CHANGEWORD]
2000 * m4.h: Declare external user_word_regexp.
2001 * m4.c: Declare user_word_regexp, and initialize it from
2002 --word-regexp or -W, or NULL if not specified.
2003 * input.c: Use user_word_regexp if specified, instead of
2004 DEFAULT_WORD_REGEXP.
2006 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2009 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2010 * checks/Makefile.in: Empty the suffix list.
2011 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2013 * m4.c: Declare nesting_limit and initialize it to 250.
2014 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2016 * m4.h: Declare nesting_limit as external.
2017 * macro.c (expand_macro): Stop execution whenever nesting limit
2019 Reported by Bengt Mertensson.
2021 * eval.c (evaluate): Diagnose excess characters in eval input.
2022 Things like `eval(08)' used to return 0 with no diagnostic.
2024 * m4.h: Capitalize first letter of all macro arguments in
2027 * m4.c: Declare warning_status, initialize it to 0. Add new
2028 option -E, or --fatal-warnings, which sets warning_status to
2029 EXIT_FAILURE instead.
2030 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2031 EXIT_FAILURE if not otherwise done by header files.
2032 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2033 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2034 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2035 argument of all M4ERROR calls.
2036 Reported by Noah Friedman.
2038 * examples/incl-test.m4: Renamed from incl_test.m4.
2039 * examples/include.m4: Include incl-test.m4 instead of
2041 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2043 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2045 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2046 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2047 also tested it on a Sun Sparc workstation running SunOS 4.x.
2049 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2050 49.format check, abusing a `union values' argument with sprintf
2051 without selecting the proper field. Now, save the formatting type
2052 first, delaying the fetch of the corresponding argument.
2053 Reported by Joseph E. Sacco and Tom Quinn.
2055 * format.c (format): Remove const from char *fmt declaration when
2056 not HAVE_EFGCVT, because a NUL may be forced into it.
2058 * m4.h: Declare atof() when not STDC_HEADERS.
2059 Reported by Joseph E. Sacco.
2061 * Regenerate configure using Autoconf 1.11, this corrects a
2062 problem about an incorrect cpp seting on NeXT 3.1.
2063 Reported by Alexander Lehmann.
2065 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2067 * m4.h (_): Change argument from `x' to `Args'.
2069 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2071 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2072 bringing more evil than good on a few systems.
2073 Reported by Greg A. Woods.

2082 * stackovf.c: New file implementing stack-overflow detection.
2083 * configure.in: Check for getrlimit, sigaction. If all of
2084 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2085 substitute ${U}stackovf.o for STACKOVF.
2086 * acconfig.h: Declare USE_STACKOVF.
2087 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2088 * m4.h: Declare setup_stackovf_trap().
2089 * m4.c: Call setup_stackovf_trap().
2090 * tests/stackovf_test.sh: New file.
2092 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2094 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2096 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2098 Sun Jan 30 14:24:19 1994 (pinard at icule)
2100 * m4.h: Remove definition of volatile, not used anymore.
2101 Reported by Jim Meyering and Joseph E. Sacco.
2103 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2104 of `if ... else /* nothing */' for if macros.
2105 Reported by Jim Meyering.
2107 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2108 warning from gcc about `repl' possibly used before defined.
2109 Reported by Jim Meyering.
2111 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2112 Reported by Jim Meyering.
2114 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2116 * m4.h: Move the conditional definition of volatile after the
2117 inclusion of system files, because they may define it first.
2119 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2121 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2122 get around a problem with Alpha make seeing a syntax error, there.
2123 Reported by Vern Paxson.
2125 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2127 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2128 Reported by Richard Stallman.
2130 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2132 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2133 instead of AC_HAVE_FUNCS.
2134 Reported by Noah Friedman.

2138 * m4.c: Initialize show_help and show_version to zero.
2140 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2141 Use them in exit() and usage() calls.
2143 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2145 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2146 syserr() macro. Delete errref, add reference_error and M4ERROR.
2147 * m4.c: Replace errref, which was returning an input reference
2148 string, with reference_error, which prints it on standard error.
2149 * builtin.c, output.c: Use errno as second parameter to error,
2150 instead of using syserr() with %s.
2151 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2152 Doing so, the program name appears after the input reference
2153 instead of before, which eases M-x next-error processing.
2155 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2157 * checks/get-them: Escape braces with backslashes in patterns,
2158 because HPUX-9.01 awk needs this.

2167 Declare xrealloc, for use in errref().
2168 * m4.c: Delete error_message_prefix() function, add errref().
2169 * *.c: Use error() systematically in place of all error macros,
2170 now that error() flushes stdout first. Make needed adjustments.
2172 * m4.h: Remove const in sys_errlist[] declaration, it creates
2173 conflicts on SGI and Alpha.
2174 Reported by Kaveh R. Ghazi.
2176 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

2192 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2194 * input.c (input_init): Initialize quote and comment strings
2195 explicitely instead of calling set_quotes and set_comment: by
2196 doing so, we ensure we do not free uninitialized variables.
2198 * checks/check-them: Reverse arguments to both diff, so the
2199 expected is on the left and the obtained on the right.
2201 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2202 macros. Delete declarations for m4error, warning, fatal and
2203 internal_error, add declaration for error_message_prefix.
2204 * m4.c: Delete m4error, warning, fatal and internal_error
2205 routines, add error_message_prefix routine.
2206 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2207 warning with WARNING*, fatal with FATAL* and internal_error with
2209 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
2210 this is not needed anymore.
2212 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
2213 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
2214 and debug_message, add declaration for debug_message_prefix.

2216 Delete debug_print and debug_message routines, add
2217 debug_message_prefix routine.
2218 * builtin.c, debug.c: Replace debug_print routine calls with
2219 DEBUG_PRINT* macro calls.

2225 (trace_format): Use stdarg instead of varargs if __STDC__.
2227 * configure.in: Remove checks for vfprintf and _doprnt. These
2228 implementations use varargs tricks which are not portable enough.
2229 * lib/vfprintf.c: Deleted.
2230 * lib/_doprnt.c: Deleted.
2231 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
2232 Reported by Joel Sherrill.

2250 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
2251 Reported by Joel Sherrill.
2253 * builtin.c (prefix_all_builtins): Instead of the table size, use
2254 the null entry at end for stopping the loop. It was overwritten.
2255 Reported by Andreas Schwab and Jim Meyering.
2257 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
2258 Reported by Kaveh R. Ghazi.

2280 Reported by Tom McConnell.
2282 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
2286 * configure.in: Do not copy check files in the build hierarchy.
2287 * checks/check-them: Identify the m4 version being checked. For
2288 finding m4, look in $PATH instead of in the parent directory.
2289 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
2290 * checks/Makefile.in (.all-stamp): Always create check files in
2291 the source hierarchy, not anymore in the build hierarchy.

2336 * configure.in: Add (commented) checks for fileno and fstat.
2337 Reported by Jim Avera.
2339 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,

2514 * lib/alloca.c: New, from elsewhere.
2515 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2517 * m4.h: Do not define index/rindex if already defined. If
2518 FALSE/TRUE are already defined, do not redefine them, but merely
2519 define boolean typedef to int.
2521 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2522 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2523 because some C compilers do not like connectives with #ifdef.
2524 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2525 __GNUC__ and once for __STDC__.
2526 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2528 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2529 Makefile dependencies. Without it, make keeps destroying and
2530 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2532 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2533 to diversion/DIVERSION, this was a spelling error.
2535 * m4.c: Declare version[], remove #include "version.h".
2536 * version.h: Deleted.
2537 * Makefile.in: Remove references to version.h.
2539 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2540 production, by using a simpler and more robust algorithm. This
2541 solves the problem of synclines sometimes written in the middle of
2542 an output line. Delete sync_line() and output_lines variable.
2543 * m4.h: Remove sync_line prototype and output_lines declaration.
2544 * input.c (next_char), output.c (shipout_text): Remove references
2546 * input.c (push_file, pop_file): Merely put the value -1 in
2547 output_current_line instead of calling sync_line, for delaying a
2548 single `#line NUM FILE' before next output line. Do not test
2549 for sync_output, because this is unnecessary clutter.
2550 * output.c (make_divertion, insert_divertion): Idem.
2551 * input.c: Rename must_advance_line to start_of_input_line, for
2554 * debug.c (trace_header): Select a new debug line format, which
2555 better complies with GNU standards for formatting error messages.
2556 With option `-dfl', M-x next-error might be used on the output.
2557 * m4.c (vmesg): Adjust format of error output to GNU standards.
2558 * m4.texinfo: Adjust examples for `make check' to work.
2560 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2561 case for enum debug_info constants, which were all lower case.
2563 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2565 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2566 collected patches. I tried a few times using newer regex.[ch], it
2567 mysteriously stopped aborting with this one. Insecure feeling...
2568 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2570 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2572 * m4.c: Change `--no-warnings' to `--silent'.
2573 Reported by David MacKenzie.
2575 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2576 leave it off for now. See comment in m4.c for justification.
2577 Reported by David MacKenzie.
2579 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2580 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2582 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2584 * Makefile.in: Ensure recursive cleaning is done before local
2585 cleaning for all clean goals.
2587 * builtin.c (ntoa): Ensure the value is always interpreted as a
2588 signed quantity, whatever the radix is.
2590 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2592 * builtin.c, format.c, input.c: Split long lines.
2593 * m4.c: Use typedef macro_definition instead of struct
2595 * symtab.c: Use typedef symbol instead of struct symbol.
2597 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2599 * *.[ch]: Remove all trailing whitespace, in code and comments.
2601 * configure.in: Find some awk.
2602 * Makefile.in: Add $(AWK) to MDEFINES.
2603 * checks/Makefile.in: Transmit $(AWK) to get_them.
2604 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2605 awk script when switching files, because without this, mawk runs
2606 out of file descriptors.
2608 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2610 * Makefile.in (realclean): Delete m4.info*.
2611 Reported by Jim Meyering.
2613 * Makefile.in: Adjust and link with checks/Makefile.
2614 * checks/Makefile.in: New.
2615 * configure.in: Output checks/Makefile.
2617 * checks/get_them: Have the dnl header of each test more
2618 recognizable by next-error, also use a better message.
2620 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2622 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2623 And use that only if __GNUC__ since we're using it's GCC-specific
2624 semantics that tell the compiler the associated function doesn't
2627 * builtin.c (substitute): Don't use character as an array index.
2628 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2629 warnings with gcc -W -Wall on systems with qsort prototype.
2630 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2633 * eval.c (most functions): Add parentheses to assignments used
2634 as truth values go avoid warnings from gcc -Wall.
2636 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2637 any functions that don't need external scope.
2639 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2640 (many functions and arrays): Declare `const'.
2642 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2644 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2645 removing the declaration from m4.h. Also rename false to FALSE
2648 * lib/Makefile.in (Makefile): New goal.
2650 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2651 so heavily loaded. It gets more easily overridable, calling make.
2652 Reported by Jim Meyering.
2654 * Makefile.in (dist): Get .fname from the current directory name,
2655 instead of from version.h. I need updating many files manually,
2656 when the version changes, version.h is just one of them.
2658 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2660 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2661 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2662 Reported by Tom McConnell.
2664 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2666 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2667 39.cleardiv, which were describing missing or spurious newlines.
2668 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2669 do not depend on machine word size, `/bin/false' implementation,
2670 or `wc' output format. `make check' is more dependable, now.
2672 * checks/check_them: Summarize the failed tests by listing their
2673 name, at end. If none, issue `All checks successful'. Output
2674 `Checking' instead of `Input file:'.
2676 * checks/get_them, checks/check_them: Reindented.
2678 * Makefile.in (dist): chmod a+r before making the tar file.
2680 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2682 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2684 * input.c (next_token): Reinitialize token_buttom just after using
2685 it as a watermark with obstack_free. Or else, a future token, big
2686 enough for triggering reallocation of the obstack chunk, could
2687 void the initialized value of token_buttom, later causing panic in
2688 obstack_free. Rename token_buttom to token_bottom everywhere.
2690 * m4.h: Before declaring errno, first include <errno.h> and
2691 ensure that it does not define errno.
2692 Reported by Richard Stallman.
2694 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
2696 * builtin.c: Define and use DECLARE macro for builtins.
2698 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
2699 argument, this is a common idiom for introducing long comments.
2701 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
2702 arguments. The last argument was silently ignored.
2704 * m4.c (cmd_error): Add a missing semicolon before va_end().
2706 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
2708 * Makefile.in: Now handle protoized sources. Define and use U.
2709 Compile and use ansi2knr with old compilers. Update DISTFILES.
2710 Add `aclocal.m4' to `configure' dependencies.
2711 * ansi2knr.c: New, from Ghostscript distribution.
2712 * configure.in: Define U through FP_PROTOTYPES for old compilers.
2713 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
2714 * aclocal.m4: New, provide FP_PROTOTYPES.
2715 * m4.h: Conditionnaly protoized through Args, save for varags.
2716 * builtin.c: Protoized. Then:
2717 Include <sys/types.h> if size_t is not defined, before "regex.h".

2720 (m4_regexp): Add const to `msg' declaration.
2721 (m4_patsubst): Add const to `msg' declaration.
2722 * debug.c: Protoized, save for varargs.
2723 * eval.c: Protoized.
2724 * format.c: Protoized.
2725 * input.c: Protoized.
2726 * m4.c: Protoized, save for varargs. Then:
2727 (xfree): Accept void * instead of char *.
2728 (xmalloc): Return void * instead of char *.
2729 (xrealloc): Accept and return void * instead of char *.
2730 * macro.c: Protoized.
2731 * output.c: Protoized.
2732 * path.c: Protoized. Then cast some (char *) over xmalloc's.
2733 * symtab.c: Protoized.
2735 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
2737 * m4.texinfo: Remove directory from diagnostics in 30.include,
2738 51.eval, 56.errprint and 57.m4exit tests.
2740 * m4.h: Remove declarations for int or void system functions, they
2741 cause more conflicting trouble than they make good.
2743 * configure.in: Avoid configuration header file. Add some tests.
2744 * m4.h: Remove #include "config.h".
2745 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
2746 Then, rewritten for better compliance with GNU standards.
2748 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
2750 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
2751 because of a misplaced #endif.

2767 * version.h: De-automatize, force value in.
2769 * m4.c: Changes in order to use a newer getopt.h.
2770 Reported by David MacKenzie.
2772 * checks/: New name for examples/.
2773 * checks/get_them: New location for etc/get_examples.
2774 * checks/check_them: New location for etc/check_examples.

2803 Reported by Richard Stallman.
2805 * config/hmake-unicos, config/s-unicos.h: New files.
2806 Reported by Hal Peterson.
2808 * eval.c (exp_term): Have N^0 return 1.
2809 Reported by Michael Fetterman.
2811 * eval.c, input.c, m4.h: Remove last comma in enums.

2830 * The built-in format can now be configured to use sprintf as
2831 the formatting engine, for systems without [efg]cvt(3).
2833 * GNU library code is moved to the ./lib subdirectory; other
2834 utility files are now in ./etc.
