1039 * src/output.c (insert_file): Don't assume errno has a valid
1040 value simply because fread returns zero. This fixes a
1041 portability bug reported by Marion Hakanson in
1042 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

1093 mkstemp rather than mktemp. (trivial change)
1095 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1097 * src/builtin.c (expand_ranges): Added break after trailing dash.

1164 of $U, put underline in extensions rather than in basenames. Use
1165 implicit rules, now that regularity makes this possible.
1166 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation

1168 * configure.in: Adjusted for correct STACKOVF substitution.
1169 * src/debug.c (trace_format): When not __STDC__, use (...) as a

1268 Reported by Kaveh R. Ghazi.
1270 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1271 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1272 specify it.
1274 * configure.in: Use date instead of touch for stamp-h.

1326 Reported by Jim Meyering.
1328 Solidify frozen files with respect to -P:
1329 * src/m4.c: Have -P set prefix_all_buitins variable instead of
1330 calling a function by that name. Declare the variable.
1331 * src/m4.h: Adjust declaration for prefix_all_buitins.
1332 * src/builtin.c (builtin_init): Merge in functionality from
1333 previous prefix_all_buitins function, while making entries in the

1337 because *many* compilers do not accept an empty `default:'.
1338 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1339 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1341 * configure.in: Use AC_TYPE_SIGNAL.

1423 * freeze.c: New file.
1424 * Makefile.in: Compile it, distribute it.
1425 * m4.c: Recognize, document and process --freeze-state (-F) and

1533 instead of using sscanf which stops as soon as there is a
1534 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
1535 and divert(1xyzzy) were all accepted without any warning or error
1536 messages.
1537 * m4.h: Declare strtol as long if not including stdlib.h.
1538 * configure.in: Check for limits.h, and replace strtol if missing.
1539 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
1540 * lib/strtol.c: New file, from elsewhere.
1541 Reported by Andreas Schwab.
1543 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
1545 * macro.c (expand_macro): Cast value to (boolean) prior to
1546 assigning it to traced.
1547 Reported by Tom McConnell.
1549 * Makefile.in (m4): Always make all in lib first.
1550 Reported by Jim Meyering.
1552 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
1554 * stackovf.c: Isolated OS-dependent sections; Improved portability,
1555 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
1556 handlers), and a default error message if the fault address is not
1557 available (when neither siginfo.h nor BSD sigcontext are supported).
1558 * configure.in: Changes for stackovf.h: Check for sigcontext,
1559 sigaction, sigstack, and define rlim_t as int if necessary.
1560 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
1561 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
1562 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
1564 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
1566 * configure.in: Use AC_SET_MAKE.
1567 * Makefile.in: Use @SET_MAKE@.
1568 Reported by Jim Meyering.
1570 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
1571 Reported by Ian Taylor.
1573 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
1575 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
1576 because siginfo.h is unrelated to standard headers, and siginfo.h
1577 is already checked for.
1578 Reported by Joseph E. Sacco.
1580 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
1581 PROTOTYPES.
1582 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
1583 AC_PROTOTYPES.
1585 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
1587 * builtin.c (substitute): Use \& to represent this part of the
1588 string which was matched by the whole regexp, instead of
1589 representing the whole string. Any usage of \0 issues a warning
1590 and acts like \&, it will disappear in some subsequent release.
1592 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
1594 * m4.c: Complete prototype for forwarded declaration of usage.
1596 * input.c (init_macro_token): Correct own reference in error
1597 message. Previous name get_macro_func was referred to instead.
1598 (next_char): Correct own reference in error message. Previous
1599 name advance_input was referred to instead.
1601 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
1602 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
1603 and_term, not_term, logical_not_term, cmp_term, shift_term,
1604 add_term, mult_term, exp_term, unary_term, simple_term): Add
1605 prototype to forwarded declarations. Declare parameter v1 as
1606 eval_t * instead of int *. Same for local variable v2 in dyadic
1607 functions. Same for result in exp_term.
1608 * builtin.c (m4_eval): Declare value as eval_t instead of int.
1609 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
1610 unsigned_eval_t instead of unsigned int. Change casts accordingly.
1611 (shipout_int): Cast first argument of ntoa to eval_t.
1612 Reported by Thorsten Ohl.
1614 * macro.c: Complete the prototypes of forwarded expand_macro and
1615 expand_token.
1616 Reported by Thorsten Ohl.
1618 * m4.h: Define voidstar as void * or char * depending on __STDC__.
1619 The Ultrix 3.1 compiler cannot do much with void pointers.
1621 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
1622 * m4.c (xfree): Replace void * by voidstar.
1623 Reported by Tom McConnell.
1625 * ansi2knr.1: New, from elsewhere.
1626 * Makefile.in (DISTFILES): Distribute ansi2knr.1
1628 * Makefile.in (stamp-h.in): Avoid running ./config.status if
1629 stamp-h does not exist yet. This avoids running it a second time
1630 just after the initial ./configure.
1631 Reported by David MacKenzie and Tom McConnell.
1633 * m4.h: Replace the enum debug_info declaration with a series of
1634 #define's. The Ultrix 3.1 compiler would otherwise need casting
1635 (int) to most references, when used in expressions.
1636 Reported by Tom McConnell.
1638 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
1640 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
1641 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
1642 calls the compiler. Previously, FP_PROTOTYPES was only calling
1643 the preprocessor; by not being subject to CFLAGS, this was
1644 discouraging those flags asking for ANSI compilation.
1645 * acconfig.h: Document HAVE_PROTOTYPES.
1646 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
1647 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
1648 Reported by Eric Backus.
1650 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
1651 from the environment. Default CFLAGS to -g if not set.
1652 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
1653 * lib/Makefile.in: Have CFLAGS substituted from configure.
1654 Reported by Eric Backus and Tom McConnell.
1656 * configure.in: m4_undefine changeword before using AC_ENABLE.
1658 * m4.h: Declare prototypes for error (for ANSI compilers only),
1659 prefix_all_builtins and reference_error.
1660 Reported by Tom McConnell.
1662 * input.c (set_word_regexp): Do not try to initialize the array
1663 test from a string, this does not work with non-ANSI compilers.
1664 Reported by Eric Backus.
1666 * Makefile.in (dist): Clean examples/ before saving it.
1667 (distclean-local): Also remove stamp-h.
1668 Reported by Eric Backus.
1670 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
1671 non ANSI compilers.
1672 Reported by Tom McConnell.
1674 * checks/Makefile.in (clean): Depends on mostlyclean.
1675 (mostlyclean): New goal.
1677 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
1679 * Makefile.in (DISTFILES): Distribute install.sh.
1680 * install.sh: New file, copied from elsewhere.
1681 Reported by Assar Westerlund and Kaveh R. Ghazi.
1683 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
1685 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
1686 * acconfig.h: Explain ENABLE_CHANGEWORD.
1688 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
1689 from code provided by Pete Chown]
1690 * m4.h: Add original_text field to u_t variant of union u.
1691 Declare TOKEN_DATA_FUNC macro.
1692 * builtin.c: Declare changeword.
1693 (m4_changeword): New function.
1694 * input.c: Include "regex.h", define variables with word regexps.
1695 (input_init): Initialize the word regexp.
1696 (set_word_regexp): New.
1697 (next_token): Declare local variables, use the previous code if
1698 default_word_regexp is true. Else, match using a new code. Save
1699 the original text.
1700 * macro.c (expand_token): Ship out original text if not a macro
1701 name.
1702 Reported by Krste Asanovic and Pete Chown.
1704 [These modifs all depend upon ENABLE_CHANGEWORD]
1705 * m4.h: Declare external user_word_regexp.
1706 * m4.c: Declare user_word_regexp, and initialize it from
1707 --word-regexp or -W, or NULL if not specified.
1708 * input.c: Use user_word_regexp if specified, instead of
1709 DEFAULT_WORD_REGEXP.
1711 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
1712 agree with it.
1714 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
1715 * checks/Makefile.in: Empty the suffix list.
1716 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
1718 * m4.c: Declare nesting_limit and initialize it to 250.
1719 Implement -LNUMBER or --nesting-limit=NUMBER to change its
1720 value.
1721 * m4.h: Declare nesting_limit as external.
1722 * macro.c (expand_macro): Stop execution whenever nesting limit
1723 is exceeded.
1724 Reported by Bengt Mertensson.
1726 * eval.c (evaluate): Diagnose excess characters in eval input.
1727 Things like `eval(08)' used to return 0 with no diagnostic.
1729 * m4.h: Capitalize first letter of all macro arguments in
1730 definitions.
1732 * m4.c: Declare warning_status, initialize it to 0. Add new
1733 option -E, or --fatal-warnings, which sets warning_status to
1734 EXIT_FAILURE instead.
1735 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
1736 EXIT_FAILURE if not otherwise done by header files.
1737 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
1738 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
1739 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
1740 argument of all M4ERROR calls.
1741 Reported by Noah Friedman.
1743 * examples/incl-test.m4: Renamed from incl_test.m4.
1744 * examples/include.m4: Include incl-test.m4 instead of
1745 incl_test.m4.
1746 * examples/multiquotes.m4: Renamed from multi-quotes.m.
1748 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
1750 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
1751 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
1752 also tested it on a Sun Sparc workstation running SunOS 4.x.
1754 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
1755 49.format check, abusing a `union values' argument with sprintf
1756 without selecting the proper field. Now, save the formatting type
1757 first, delaying the fetch of the corresponding argument.
1758 Reported by Joseph E. Sacco and Tom Quinn.
1760 * format.c (format): Remove const from char *fmt declaration when
1761 not HAVE_EFGCVT, because a NUL may be forced into it.
1763 * m4.h: Declare atof() when not STDC_HEADERS.
1764 Reported by Joseph E. Sacco.
1766 * Regenerate configure using Autoconf 1.11, this corrects a
1767 problem about an incorrect cpp seting on NeXT 3.1.
1768 Reported by Alexander Lehmann.
1770 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
1772 * m4.h (_): Change argument from `x' to `Args'.
1774 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
1776 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
1777 bringing more evil than good on a few systems.
1778 Reported by Greg A. Woods.
1780 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
1782 * m4.h: Rename Args() to _().
1783 * m4.h: Remove extern specifier from all function declarations.
1785 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
1787 * stackovf.c: New file implementing stack-overflow detection.
1788 * configure.in: Check for getrlimit, sigaction. If all of
1789 standard headers, getrlimit and sigaction, define USE_STACKOVF and
1790 substitute ${U}stackovf.o for STACKOVF.
1791 * acconfig.h: Declare USE_STACKOVF.
1792 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
1793 * m4.h: Declare setup_stackovf_trap().
1794 * m4.c: Call setup_stackovf_trap().
1795 * tests/stackovf_test.sh: New file.
1797 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
1799 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
1801 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
1803 Sun Jan 30 14:24:19 1994 (pinard at icule)
1805 * m4.h: Remove definition of volatile, not used anymore.
1806 Reported by Jim Meyering and Joseph E. Sacco.
1808 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
1809 of `if ... else /* nothing */' for if macros.
1810 Reported by Jim Meyering.
1812 * builtin.c (m4_regexp): Reorganize the code for avoiding a
1813 warning from gcc about `repl' possibly used before defined.
1814 Reported by Jim Meyering.
1816 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
1817 Reported by Jim Meyering.
1819 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
1821 * m4.h: Move the conditional definition of volatile after the
1822 inclusion of system files, because they may define it first.
1824 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
1826 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
1827 get around a problem with Alpha make seeing a syntax error, there.
1828 Reported by Vern Paxson.
1830 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
1832 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
1833 Reported by Richard Stallman.
1835 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
1837 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
1838 instead of AC_HAVE_FUNCS.
1839 Reported by Noah Friedman.
1841 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
1843 * m4.c: Initialize show_help and show_version to zero.
1845 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
1846 Use them in exit() and usage() calls.
1848 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
1850 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
1851 syserr() macro. Delete errref, add reference_error and M4ERROR.
1852 * m4.c: Replace errref, which was returning an input reference
1853 string, with reference_error, which prints it on standard error.
1854 * builtin.c, output.c: Use errno as second parameter to error,
1855 instead of using syserr() with %s.
1856 * *.c: Use M4ERROR instead of error: no more errref() with %s.
1857 Doing so, the program name appears after the input reference
1858 instead of before, which eases M-x next-error processing.
1860 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
1862 * checks/get-them: Escape braces with backslashes in patterns,
1863 because HPUX-9.01 awk needs this.
1864 Reported by Jim Meyering.
1866 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
1868 * builtin.c: Declare "FILE *popen ();".
1870 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
1871 macros, replace error_message_prefix() declaration by errref()'s.
1872 Declare xrealloc, for use in errref().
1873 * m4.c: Delete error_message_prefix() function, add errref().
1874 * *.c: Use error() systematically in place of all error macros,
1875 now that error() flushes stdout first. Make needed adjustments.
1877 * m4.h: Remove const in sys_errlist[] declaration, it creates
1878 conflicts on SGI and Alpha.
1879 Reported by Kaveh R. Ghazi.
1881 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
1883 * m4.c: Include <getopt.h> instead of "getopt.h".
1885 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
1886 * acconfig.h: New, for documenting HAVE_EFGCVT.
1887 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
1888 use them wherever appropriate. Also use -I. for compilations.
1889 * lib/Makefile.in: Use -I.. for compilations.
1890 * *.c: Include <config.h> or "config.h".
1892 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
1893 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
1895 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
1897 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
1899 * input.c (input_init): Initialize quote and comment strings
1900 explicitely instead of calling set_quotes and set_comment: by
1901 doing so, we ensure we do not free uninitialized variables.
1903 * checks/check-them: Reverse arguments to both diff, so the
1904 expected is on the left and the obtained on the right.
1906 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
1907 macros. Delete declarations for m4error, warning, fatal and
1908 internal_error, add declaration for error_message_prefix.
1909 * m4.c: Delete m4error, warning, fatal and internal_error
1910 routines, add error_message_prefix routine.
1911 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
1912 warning with WARNING*, fatal with FATAL* and internal_error with
1913 INTERNAL_ERROR*.
1914 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
1915 this is not needed anymore.
1917 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
1918 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
1919 and debug_message, add declaration for debug_message_prefix.
1920 * debug.c: Remove static specifier for FILE *debug declaration.
1921 Delete debug_print and debug_message routines, add
1922 debug_message_prefix routine.
1923 * builtin.c, debug.c: Replace debug_print routine calls with
1924 DEBUG_PRINT* macro calls.
1925 * input.c, path.c: Replace debug_message routine calls with
1926 DEBUG_MESSAGE* macro calls.
1928 * m4.h: Remove inclusion of <varargs.h>.
1929 * debug.c: Include <stdarg.h> or <varargs.h>.
1930 (trace_format): Use stdarg instead of varargs if __STDC__.
1932 * configure.in: Remove checks for vfprintf and _doprnt. These
1933 implementations use varargs tricks which are not portable enough.
1934 * lib/vfprintf.c: Deleted.
1935 * lib/_doprnt.c: Deleted.
1936 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
1937 Reported by Joel Sherrill.
1939 * path.c (add_include_directory): Use xstrdup.
1941 * builtin.c (find_builtin_by_name): Declare static.
1943 * *.[ch]: Add const to a few "char *" declarations.

1946 * debug.c: Remove comments about HAVE_FILENO and HAVE_FSTAT.
1948 * debug.c (debug_flush_files): New.
1949 * m4.h: Declares it.
1950 * builtin.c (m4_syscmd, m4_esyscmd): Use it.
1951 Reported by Nicolas Pioch.
1953 Fri Nov 12 10:02:26 1993 Francois Pinard (pinard@icule)
1955 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
1956 Reported by Joel Sherrill.
1958 * builtin.c (prefix_all_builtins): Instead of the table size, use
1959 the null entry at end for stopping the loop. It was overwritten.
1960 Reported by Andreas Schwab and Jim Meyering.
1962 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
1963 Reported by Kaveh R. Ghazi.
1965 * macro.c (call_macro): Add * in (*SYMBOL_FUNC (sym)) (...).
1966 Reported by Karl Vogel.
1968 Tue Nov 9 09:31:47 1993 Francois Pinard (pinard@icule)
1970 * m4.h: Do not define volatile if already defined.
1971 Reported by Rene' Seindal.
1973 * lib/Makefile.in: Add a forgotten ALLOCA=@ALLOCA@. Grrr!
1975 Reported by Bernhard Daeubler, Eric Backus, Hal Peterson, Hoang
1976 Uong, Ian Taylor, Kaveh R. Ghazi, Tom McConnell and Walter Wong.
1978 Mon Nov 8 21:11:44 1993 Francois Pinard (pinard@icule)
1980 * m4.h: Define strchr and strrchr in terms of index and rindex,
1981 instead of the other way around.
1982 * builtin.c, m4.c, path.c: Use strchr instead of index.
1984 * input.c (next_char): Remove a "break;" after a "return ...;".
1985 Reported by Tom McConnell.
1986 \f
1987 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
1989 * Release 1.1
1991 * configure.in: Do not copy check files in the build hierarchy.
1992 * checks/check-them: Identify the m4 version being checked. For
1993 finding m4, look in $PATH instead of in the parent directory.
1994 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
1995 * checks/Makefile.in (.all-stamp): Always create check files in
1996 the source hierarchy, not anymore in the build hierarchy.
1997 (check): cd to the source hierarchy before performing checks.
1998 Do not copy nor clean COPYING anymore, take it from `..'.
1999 Reported by Tom McConnell.
2001 * Makefile.in (Makefile): Use $(SHELL).
2002 (config.status): Use $(SHELL). Use "config.status --recheck"
2003 instead of "configure --no-create", which is obsolete.
2004 Reported by Tom McConnell.
2006 Fri Nov 5 09:49:30 1993 Francois Pinard (pinard@compy.IRO.UMontreal.CA)
2008 * m4.c (usage): Use "%s" instead of "m4" in format string.
2009 Reported by Jim Meyering.
2011 * Makefile.in: Distribute mkinstalldirs.
2012 Reported by Pierre Gaumond.
2013 Reported by Jim Meyering.
2014 Reported by Tom McConnell.
2015 Reported by Andreas Gustafsson.
2017 * checks/check-them: Renamed from checks/check_them.
2018 * checks/get-them: Renamed from checks/get_them.
2019 * checks/.all-stamp: Renamed from checks/.all_stamp.
2020 * checks/Makefile.in: Changed accordingly.
2021 Reported by Jim Meyering.
2023 Thu Nov 4 13:50:52 1993 Francois Pinard (pinard@lagrande.IRO.UMontreal.CA)

2190 macro.c, output.c, path.c, symtab.c: Change Copyright from
2191 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.

2201 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
2203 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
2204 might well use CFLAGS is s/he needs it.
2206 * Makefile.in: Allow installation of info files from a separate
2207 build directory.
2208 Reported by Jason Merrill.
2209 Reported by David MacKenzie.
2210 Reported by Skip Montanaro.

2214 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
2216 * Release 1.0.3
2217 This is still a beta release for the future GNU m4 version 1.1.
2219 * lib/alloca.c: New, from elsewhere.
2220 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2222 * m4.h: Do not define index/rindex if already defined. If
2223 FALSE/TRUE are already defined, do not redefine them, but merely
2224 define boolean typedef to int.
2226 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2227 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2228 because some C compilers do not like connectives with #ifdef.
2229 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2230 __GNUC__ and once for __STDC__.
2231 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2233 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2234 Makefile dependencies. Without it, make keeps destroying and
2235 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2237 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2238 to diversion/DIVERSION, this was a spelling error.
2240 * m4.c: Declare version[], remove #include "version.h".
2241 * version.h: Deleted.
2242 * Makefile.in: Remove references to version.h.
2244 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2245 production, by using a simpler and more robust algorithm. This
2246 solves the problem of synclines sometimes written in the middle of
2247 an output line. Delete sync_line() and output_lines variable.
2248 * m4.h: Remove sync_line prototype and output_lines declaration.
2249 * input.c (next_char), output.c (shipout_text): Remove references
2250 to output_lines.
2251 * input.c (push_file, pop_file): Merely put the value -1 in
2252 output_current_line instead of calling sync_line, for delaying a
2253 single `#line NUM FILE' before next output line. Do not test
2254 for sync_output, because this is unnecessary clutter.
2255 * output.c (make_divertion, insert_divertion): Idem.
2256 * input.c: Rename must_advance_line to start_of_input_line, for
2257 consistency.
2259 * debug.c (trace_header): Select a new debug line format, which
2260 better complies with GNU standards for formatting error messages.
2261 With option `-dfl', M-x next-error might be used on the output.
2262 * m4.c (vmesg): Adjust format of error output to GNU standards.
2263 * m4.texinfo: Adjust examples for `make check' to work.
2265 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2266 case for enum debug_info constants, which were all lower case.
2268 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2269 re_search_2.
2270 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2271 collected patches. I tried a few times using newer regex.[ch], it
2272 mysteriously stopped aborting with this one. Insecure feeling...
2273 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2275 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2277 * m4.c: Change `--no-warnings' to `--silent'.
2278 Reported by David MacKenzie.
2280 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2281 leave it off for now. See comment in m4.c for justification.
2282 Reported by David MacKenzie.
2284 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2285 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2287 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2289 * Makefile.in: Ensure recursive cleaning is done before local
2290 cleaning for all clean goals.
2292 * builtin.c (ntoa): Ensure the value is always interpreted as a
2293 signed quantity, whatever the radix is.
2295 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2297 * builtin.c, format.c, input.c: Split long lines.
2298 * m4.c: Use typedef macro_definition instead of struct
2299 macro_definition.
2300 * symtab.c: Use typedef symbol instead of struct symbol.
2302 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2304 * *.[ch]: Remove all trailing whitespace, in code and comments.
2306 * configure.in: Find some awk.
2307 * Makefile.in: Add $(AWK) to MDEFINES.
2308 * checks/Makefile.in: Transmit $(AWK) to get_them.
2309 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2310 awk script when switching files, because without this, mawk runs
2311 out of file descriptors.
2313 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2315 * Makefile.in (realclean): Delete m4.info*.
2316 Reported by Jim Meyering.
2318 * Makefile.in: Adjust and link with checks/Makefile.
2319 * checks/Makefile.in: New.
2320 * configure.in: Output checks/Makefile.
2322 * checks/get_them: Have the dnl header of each test more
2323 recognizable by next-error, also use a better message.
2325 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2327 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2328 And use that only if __GNUC__ since we're using it's GCC-specific
2329 semantics that tell the compiler the associated function doesn't
2330 return.
2332 * builtin.c (substitute): Don't use character as an array index.
2333 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2334 warnings with gcc -W -Wall on systems with qsort prototype.
2335 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2336 from gcc -W -Wall.
2338 * eval.c (most functions): Add parentheses to assignments used
2339 as truth values go avoid warnings from gcc -Wall.
2341 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2342 any functions that don't need external scope.
2344 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2345 (many functions and arrays): Declare `const'.
2347 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2349 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2350 removing the declaration from m4.h. Also rename false to FALSE
2351 and true to TRUE.
2353 * lib/Makefile.in (Makefile): New goal.
2355 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2356 so heavily loaded. It gets more easily overridable, calling make.
2357 Reported by Jim Meyering.
2359 * Makefile.in (dist): Get .fname from the current directory name,
2360 instead of from version.h. I need updating many files manually,
2361 when the version changes, version.h is just one of them.
2363 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2365 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2366 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2367 Reported by Tom McConnell.
2369 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2371 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2372 39.cleardiv, which were describing missing or spurious newlines.
2373 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2374 do not depend on machine word size, `/bin/false' implementation,
2375 or `wc' output format. `make check' is more dependable, now.
2377 * checks/check_them: Summarize the failed tests by listing their
2378 name, at end. If none, issue `All checks successful'. Output
2379 `Checking' instead of `Input file:'.
2381 * checks/get_them, checks/check_them: Reindented.
2383 * Makefile.in (dist): chmod a+r before making the tar file.
2385 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2387 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2389 * input.c (next_token): Reinitialize token_buttom just after using
2390 it as a watermark with obstack_free. Or else, a future token, big
2391 enough for triggering reallocation of the obstack chunk, could
2392 void the initialized value of token_buttom, later causing panic in
2393 obstack_free. Rename token_buttom to token_bottom everywhere.
2395 * m4.h: Before declaring errno, first include <errno.h> and
2396 ensure that it does not define errno.
2397 Reported by Richard Stallman.
2399 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
2401 * builtin.c: Define and use DECLARE macro for builtins.
2403 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
2404 argument, this is a common idiom for introducing long comments.
2406 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
2407 arguments. The last argument was silently ignored.
2409 * m4.c (cmd_error): Add a missing semicolon before va_end().
2411 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
2413 * Makefile.in: Now handle protoized sources. Define and use U.
2414 Compile and use ansi2knr with old compilers. Update DISTFILES.
2415 Add `aclocal.m4' to `configure' dependencies.
2416 * ansi2knr.c: New, from Ghostscript distribution.
2417 * configure.in: Define U through FP_PROTOTYPES for old compilers.
2418 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
2419 * aclocal.m4: New, provide FP_PROTOTYPES.
2420 * m4.h: Conditionnaly protoized through Args, save for varags.
2421 * builtin.c: Protoized. Then:
2422 Include <sys/types.h> if size_t is not defined, before "regex.h".

2428 * eval.c: Protoized.
2429 * format.c: Protoized.

2432 (xfree): Accept void * instead of char *.
2433 (xmalloc): Return void * instead of char *.
2434 (xrealloc): Accept and return void * instead of char *.
2435 * macro.c: Protoized.
2436 * output.c: Protoized.
2437 * path.c: Protoized. Then cast some (char *) over xmalloc's.
2438 * symtab.c: Protoized.
2440 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
2442 * m4.texinfo: Remove directory from diagnostics in 30.include,
2443 51.eval, 56.errprint and 57.m4exit tests.
2445 * m4.h: Remove declarations for int or void system functions, they
2446 cause more conflicting trouble than they make good.
2448 * configure.in: Avoid configuration header file. Add some tests.
2449 * m4.h: Remove #include "config.h".
2450 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.

2453 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
2455 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
2456 because of a misplaced #endif.

2478 * checks/get_them: New location for etc/get_examples.
2479 * checks/check_them: New location for etc/check_examples.

2487 * Makefile.in (check): Add m4 as dependency.
2489 * m4.c: Accept --no-warnings instead of --no_warnings, and
2490 --no-gnu-extensions instead of --no_gnu_extensions. Make the
2491 usage message more informative.
2492 Reported by David MacKenzie.

2511 Reported by Hal Peterson.
2513 * eval.c (exp_term): Have N^0 return 1.
2514 Reported by Michael Fetterman.

2520 \f
2521 Thu Oct 24 15:18:46 1991 Rene' Seindal (seindal at diku.dk)
2523 * Release 1.0. Many thanks to those, who provided me with bug
2524 reports and feedback.
2526 * Uses GNU configure, taken from the gdb distribution.
2528 * Uses GNU getopt(), with long option names.
2530 * The -Q/+quiet option is added, which suppresses warnings about
2531 missing or superflous arguments to built-in macros.
