1509 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
1510 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
1512 Also, some of the files here were never updated from the previous
1513 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
1514 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.
1516 2005-03-31 Mike Frysinger <vapier@gentoo.org>
1518 * Makefile.in (bindir, infodir): Substitute from configure rather
1519 than hardcode.
1520 * doc/Makefile.in (infodir): Ditto.
1521 * src/Makefile.in (bindir): Ditto.
1522 * NEWS: Updated.
1524 2005-03-31 Gary V. Vaughan <gary@gnu.org>
1526 Changes needed to automate the release process for 1.4.3:
1528 * Makefile.in (dist): Make .tar.bz2 tarball too.
1529 * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
1530 (cvs-news): Look 1 line further down for NEWS release number.
1531 (cvs-dist): We don't use automake, so make dist is fine.
1532 Remove double . before suffixes.
1533 (cvs-release): Don't mention manual.html.
1534 (fetch): Get latest gendocs files.
1535 (web-manual): Rewritten to use gendoc for multiformat manuals.
1536 * doc/gendocs.sh: Don't save an old version in m4 CVS!
1537 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1538 preserving, but case insensitive, so generating html docs per node
1539 clashes between Index.html, the node file, and index.html, the
1540 top-level of the document tree...
1541 (Index macro): ...so renamed to this. Changed all references.
1543 2005-03-31 Gary V. Vaughan <gary@gnu.org> (tiny change)

1559 canonical versions.
1561 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)
1563 * doc/m4.texinfo (Patsubst): Re-add trailing space required by
1564 checks/47.patsubst, with a redundant @comment to prevent emacs
1565 from removing it accidentally again.
1566 * checks/get-them: Allow for trailing spaces tucked behind
1567 @comment marks.
1569 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

1595 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
1596 recognition macros.
1597 * src/freeze.c (produce_frozen_state): Use \n line-endings even
1598 on Windows, so that the frozen file reader will work.
1599 Reported by Josef T. Burger.
1601 * src/m4.c (main): Modernise the --version output.
1603 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1605 Modernise the configury a little to prevent spurious errors from
1606 Autoconf-2.59's autoreconf:
1608 * config.h.in: Renamed to...
1609 * config-h.in: ...this to better support DOS 8.3 file systems.
1610 * acconfig.h: Removed.
1611 * configure.in: Renamed to...
1612 * configure.ac: ...this, and AC_DEFINE used to declare config.h
1613 entry comments. Slight reorganisation and reformatting.
1614 * aclocal.m4: Use third argument to AC_DEFINE to declare config.h
1615 entry comments.
1616 (AC_INIT): Use a modern 3 argument call.

1619 s/PRODUCT/PACKAGE/g.
1620 * Makefile.in (DISTFILES): Removed acconfig.h, configure.in,
1621 config.h.in. Added configure.ac, config-h.in.
1622 (stamp-h.in): Removed acconfig.h from dependencies.
1623 (configure): Depends on configure.ac, not configure.in.
1624 * doc/Makefile.in (stamp-vti): Ditto.
1625 * src/freeze.c (produce_frozen_state), src/m4.c (main): Adjust for
1626 difference between PRODUCT="m4" and PACKAGE="GNU M4".
1627 * configure: Regenerated.
1629 2005-02-03 Noah Misch <noah@cs.caltech.edu>
1631 * src/output.c (mkstemp): Make non-static, and build regardless of
1632 HAVE_TMPFILE; src/builtin.c also needs this replacement.
1633 * NEWS: Update.
1635 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1637 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
1638 changes from your editor buffer first.
1640 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
1641 * src/m4.c: And include them as appropriate.
1642 * NEWS: Updated.
1644 2004-09-09 Andreas Schwab <schwab@suse.de>
1646 Refactoring of the string read case in next_char provides about a
1647 20% speedup of M4 as typically used by autoconf:
1649 * src/input.c (next_char_1): Renamed from next_char.
1650 (next_char): New macro.

1661 * configure.in (VERSION): Bump to 1.4.2.
1662 * News: Describe 1.4.2's changes.
1664 * src/m4.c (reference_error): Preserve errno, since M4ERROR
1665 relies on this.
1666 * src/builtin.c (m4_esyscmd): Clear errno before calling popen.
1667 (m4_maketemp): Clear errno before calling mkstemp.
1668 * src/path.c (path_search): Don't let "free" trash errno when
1669 returning NULL.
1670 * src/output.c (insert_file): Don't assume errno has a valid
1671 value simply because fread returns zero. This fixes a
1672 portability bug reported by Marion Hakanson in
1673 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
1675 2004-06-09 Gary V. Vaughan <gary@gnu.org>

1691 to pacify Texinfo 4.7.
1692 * doc/Makefile.in (info): Remove info-1, info-2, info-3.
1694 * src/m4.h, src/debug.c: Use #ifdef __STDC__, not #if __STDC__, to

1697 2003-09-28 Akim Demaille <akim@epita.fr>
1699 * src/symtab.c (lookup_symbol): Fix an uninitialized-variable

1717 2001-02-01 Matt Kraai <kraai@debian.org>
1719 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
1720 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1721 empty file rather than to a nonexistent file. This closes a common
1722 security hole.
1723 * src/builtin.c (m4_maketemp): Implement the above, by using
1724 mkstemp rather than mktemp. (trivial change)
1726 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1728 * src/builtin.c (expand_ranges): Added break after trailing dash.
1729 This caused misbehaviors on some systems.

1741 be opened, return immediately after producing the error message.
1742 Reported by Andreas Schwab.
1744 * configure.in: Check for const only after having found possible
1745 ANSIfying compiler flags, this is of no use to check it before.
1746 Reported by Alexander Lehmann.
1748 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
1750 * src/macro.c (collect_arguments): Cast obstack arguments to
1751 (voidstar), so avoiding compiler warnings.
1752 Reported by Joseph E. Sacco.
1754 * src/freeze.c (produce_frozen_state): Cast printed lengths to
1755 (int) so they correspond to %d format items.
1756 Reported by Joseph E. Sacco.
1758 * src/m4.c (main): Cast the argument to xfree to (voidstar).
1759 * src/symtab.c (free_symbol): Idem.
1760 Reported by Karl Vogel.
1762 Mon Oct 31 02:11:19 1994 Francois Pinard (pinard@icule)

1771 Sun Oct 30 08:13:03 1994 Francois Pinard (pinard@icule)
1773 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1774 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1775 defines __STDC__ to 0, for indicating it is *not* ANSI!
1776 Reported by Kaveh R. Ghazi.
1778 * configure.in: Added obsolescent tests for AIX and Minix.
1780 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,
1781 which texclean does not exist anymore.
1782 Reported by Eric Backus, Jim Meyering, John David Anglin and
1783 Joseph E. Sacco.

1790 * src/ansi2knr.c: New version, sent by Peter Deutsch.
1791 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
1792 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1793 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1794 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1795 of $U, put underline in extensions rather than in basenames. Use
1796 implicit rules, now that regularity makes this possible.
1797 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1798 of ansi2knr whenever it is needed.
1799 * configure.in: Adjusted for correct STACKOVF substitution.
1800 * src/debug.c (trace_format): When not __STDC__, use (...) as a
1801 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
1802 Reported by David MacKenzie.
1804 * Makefile.in: Remove binprefix. Use transform_name instead.
1805 Reported by David MacKenzie.
1807 * doc/Makefile.in: Create version.texi, use it, clean it.

1812 * Makefile.in (all, install, uninstall): Depend on Makefile.
1814 * Makefile.in: For actions invoking $(MAKE) from within compound
1815 sh statements, exit non-zero if the sub-make fails. Otherwise,
1816 the top-level make may exit successfully when it should fail.
1817 Reported by Jim Kingdon.
1819 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1821 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
1822 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
1823 * configure.in: Substitute PRODUCT and VERSION.
1825 * {,*/}Makefile.in (dist): Always try a hard link before a copy.
1827 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
1829 * Makefile.in (mostlyclean-local): Do not remove *~.
1830 * */Makefile.in (mostlyclean): Idem.
1831 Reported by Robert E. Brown and Richard Stallman.
1833 Sun Oct 9 08:30:13 1994 Francois Pinard (pinard@icule)

1840 * aclocal.m4 (fp_C_PROTOTYPES): Substitute @kr@ by kr or empty.
1841 Reported by David MacKenzie.
1843 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)
1845 * configure.in: Do not add -O to CFLAGS for GNU C, now that
1846 configure does it automatically.
1847 Reported by Jim Meyering.
1849 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
1851 * src/stackovf.c: Declare the handler_t typedef earlier in the
1852 code, use it for stackovf_handler.
1853 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
1854 casting sigsegv_handler.
1855 Reported by Robert Bernstein.
1857 * src/m4.c (main): Initialize program_name to argv[0] without
1858 basename'ing it.
1859 Reported by Karl Berry.
1861 Sun Sep 18 11:42:50 1994 Francois Pinard (pinard@icule)
1863 * src/Makefile.in (TAGS): Include a ../lib/TAGS reference.

1874 unreacheable and useless.
1876 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
1878 * lib/Makefile.in (DISTFILES): Distribute TAGS.
1879 (distclean): Do not remove TAGS.
1880 (realclean): Remove it.
1881 * Makefile.in: Make TAGS in lib also, not just in src.
1882 Reported by Karl Berry.
1884 * Makefile.in (distclean, realclean): Instead of recursively
1885 calling $(MAKE) for the -local part, allow parallel execution of
1886 -recursive and -local, only delay the removal of config.status,
1887 which is repeated in both goals.
1888 \f
1889 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
1891 * Release 1.3.
1893 * Makefile.in: Group all *clean-recursive goals in one, using sed
1894 to remove `-recursive' while calling make recursively. Also, use
1895 a subshell for each recursive $(MAKE).
1896 Reported by Jim Meyering.
1898 * src/m4.h (memcpy): Define with bcopy for BSD systems.
1899 Reported by Kaveh R. Ghazi.
1901 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1902 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1903 specify it.
1905 * configure.in: Use date instead of touch for stamp-h.
1906 * Makefile.in (stamp-h.in): Idem.
1908 * Makefile.in (distclean, realclean): Force serial execution of
1909 both goals, in case parallel makes are being used.
1910 Reported by Jim Meyering.

1913 (distclean): Do not remove TAGS.
1914 (realclean): Remove it.

1922 Thu Sep 8 15:07:27 1994 Francois Pinard (pinard@icule)
1924 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
1925 ./install.sh will not be correctly referred to in sub-Makefiles.
1926 Reported by John David Anglin.
1928 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.
1929 Reported by Eric Backus.
1931 * Makefile.in, checks/Makefile.in, doc/Makefile.in,
1932 examples/Makefile.in, lib/Makefile.in, src/Makefile.in: Limit

1936 Reported by Jim Meyering.
1938 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)

1941 care of systems having only incomplete implementations (like for
1942 Pyramid 9820 OSx 5.0d).
1943 Reported by Kaveh R. Ghazi.
1945 * src/Makefile.in (TAGS): Remote -t from etags call.
1947 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)
1949 * lib/Makefile.in (install): Depend on all.

1954 Reported by Jim Meyering and John David Anglin.
1956 * Makefile.in (distclean-local): Delete config.log.
1957 Reported by Jim Meyering.
1959 Solidify frozen files with respect to -P:
1960 * src/m4.c: Have -P set prefix_all_buitins variable instead of
1961 calling a function by that name. Declare the variable.
1962 * src/m4.h: Adjust declaration for prefix_all_buitins.
1963 * src/builtin.c (builtin_init): Merge in functionality from
1964 previous prefix_all_buitins function, while making entries in the
1965 symbol table, but not modifying the builtin description itself.
1967 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1968 because *many* compilers do not accept an empty `default:'.
1969 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1970 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1972 * configure.in: Use AC_TYPE_SIGNAL.
1973 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
1974 Reported by Robert Bernstein.
1976 * checks/Makefile.in (check): Modify PATH so check-them will find
1977 m4 in the src directory.
1978 * Makefile.in (check): Don't.
1979 Reported by Akiko Matsushita and Jim Meyering.
1981 * src/output.c (make_room_for, output_character_helper): New
1982 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
1983 a per buffer MAXIMUM_BUFFER_SIZE.
1985 * src/output.c (output_text): New function, for optimizing the
1986 output of strings of characters. Use it.
1988 Tue Aug 30 01:44:29 1994 Francois Pinard (pinard@icule)

1991 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
1992 files.
1993 * Makefile.in: Adjusted.
1994 * configure.in: Configure new Makefiles.
1996 * m4.h: Declare STRING typedef. Use it for comment and quote
1997 strings, adjusting all references. (This is the rudiments of a
1998 beginning for the eventual withdrawal of NUL terminated strings.)
1999 * output.c (shipout_text): Accept a length parameter, and use it.
2000 All callers adjusted.
2002 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
2004 * m4.h: Include <unistd.h> if it exists.
2005 * stackovf.c: Don't.
2007 Clean up for current_diversion variable:
2008 * output.c: Move current_diversion from builtin.c.

2023 Freeze diversions:
2024 * output.c (freeze_diversions): New function.
2025 * m4.h: Declare freeze_diversions.
2026 * freeze.c: Document frozen file format, revise it, call
2027 freeze_diversions to add diversions to frozen format, and code to
2028 reload them properly.
2029 * m4.c: Do not undivert automatically at end when status being
2030 frozen. Do not call builtin_init when reloading frozen state.
2032 Speed up diversion processing:
2033 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2034 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2035 structure and variables, cached variables out of output_diversion,
2036 reallocate_diversion_for and OUTPUT_CHARACTER.
2037 (shipout_text, make_diversion, insert_diversion): Adapted to new
2038 structures.
2039 (insert_file): Use better buffering.
2040 Reported by David MacKenzie.
2042 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
2044 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
2045 dist works from another build directory.
2047 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2049 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2050 constant HASHMAX, for -H option to work better.
2052 * builtin.c (DECLARE): Simplify by using _ ().
2054 * freeze.c: New file.
2055 * Makefile.in: Compile it, distribute it.
2056 * m4.c: Recognize, document and process --freeze-state (-F) and
2057 --reload-state (-R) options. Pass a true flag to builtin_init
2058 only if no reloading some state.
2059 * builtin.c (define_builtin): Remove static specifier.
2060 (find_builtin_by_name): Remove static specifier.
2061 (builtin_init): Accept and obey a flag argument.

2064 Wed Aug 24 16:14:19 1994 Francois Pinard (pinard@icule)
2066 * builtin.c (dumpdef_cmp): Rewrite so the cast protect the const
2067 specifier.
2069 * configure.in: Implement --with-dmalloc.
2070 * acconfig.h: Document WITH_DMALLOC.
2071 * m4.h: Add code for when WITH_DMALLOC.
2073 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2075 * m4.c (long_options): Use "error-output", the dash was missing.
2076 Reported by Akiko Matsushita.
2078 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2080 * m4.h: Include <sys/types.h>.
2081 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2082 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2083 int.
2084 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2085 as size_t, not int.
2086 * builtin.c (dump_args): Declare len as size_t, not int.
2088 * debug.c: Prototype the forward declaration of debug_set_file.
2090 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2091 shadowing of this variable.
2092 * output.c (insert_diversion): Idem.
2094 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2095 (input_init): Duplicate default quote and comment strings.

2099 Duplicate even default comment strings.
2101 * configure.in: Updated for Autoconf 2.0.
2102 * Makefile.in (distclean-local): Also delete config.cache.
2104 * m4.c (usage): Reorganize the --help output by topic. Include a
2105 description for debugging flags.
2107 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2109 * configure.in: If sigaction is available and SA_ONSTACK defined,
2110 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2111 defined, use sigvec. Else don't compile stackovf.c.
2112 * stackovf.c (setup_stackovf_trap): Idem.
2113 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2114 and Simon Leinen.
2116 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2118 * m4.c (usage): Replace printf par fputs.
2119 \f
2120 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2122 * Release 1.2
2124 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2126 * configure.in: Check for sigaction and sigvec. Add a new delayed
2127 check for RLIMIT_STACK, combine in the checking for getrlimit.
2128 All those things are not universally available.
2129 * stackovf.c: Split setting up the trap handler and catching
2130 signals, for better taking care of various configure outcomes.
2131 * examples/stackovf.sh: Correct a typo.
2132 Reported by Eric Backus, Jim Avera and Jim Meyering.
2134 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2136 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2138 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2140 * Makefile.in: Modify so parallel make will not try making
2141 lib/libm4.a twice simultaneously.
2142 Reported by Jim Meyering.
2144 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2146 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2147 error message, for when no code possibility exists. Even if this
2148 line is completely #ifdef'ed out, it brings a syntax error.
2149 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2151 * Makefile.in (install): Have install depend on all too, for lib
2152 to be remade as needed.
2154 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2155 providing ulimit, instead of using only ksh.
2156 Reported by Jim Avera and Joseph E. Sacco.
2158 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2160 * Makefile.in (check): Have it depend on all instead of m4. In
2161 this way, a change in lib will be detected and processed.
2163 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2164 instead of using sscanf which stops as soon as there is a
2165 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2166 and divert(1xyzzy) were all accepted without any warning or error
2167 messages.
2168 * m4.h: Declare strtol as long if not including stdlib.h.
2169 * configure.in: Check for limits.h, and replace strtol if missing.
2170 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2171 * lib/strtol.c: New file, from elsewhere.
2172 Reported by Andreas Schwab.
2174 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2176 * macro.c (expand_macro): Cast value to (boolean) prior to
2177 assigning it to traced.
2178 Reported by Tom McConnell.
2180 * Makefile.in (m4): Always make all in lib first.
2181 Reported by Jim Meyering.
2183 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2185 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2186 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2187 handlers), and a default error message if the fault address is not
2188 available (when neither siginfo.h nor BSD sigcontext are supported).
2189 * configure.in: Changes for stackovf.h: Check for sigcontext,
2190 sigaction, sigstack, and define rlim_t as int if necessary.
2191 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2192 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2193 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2195 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2197 * configure.in: Use AC_SET_MAKE.
2198 * Makefile.in: Use @SET_MAKE@.
2199 Reported by Jim Meyering.
2201 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2202 Reported by Ian Taylor.
2204 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2206 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2207 because siginfo.h is unrelated to standard headers, and siginfo.h
2208 is already checked for.
2209 Reported by Joseph E. Sacco.
2211 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2212 PROTOTYPES.
2213 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2214 AC_PROTOTYPES.
2216 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2218 * builtin.c (substitute): Use \& to represent this part of the
2219 string which was matched by the whole regexp, instead of
2220 representing the whole string. Any usage of \0 issues a warning
2221 and acts like \&, it will disappear in some subsequent release.
2223 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2225 * m4.c: Complete prototype for forwarded declaration of usage.
2227 * input.c (init_macro_token): Correct own reference in error
2228 message. Previous name get_macro_func was referred to instead.
2229 (next_char): Correct own reference in error message. Previous
2230 name advance_input was referred to instead.
2232 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2233 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2234 and_term, not_term, logical_not_term, cmp_term, shift_term,
2235 add_term, mult_term, exp_term, unary_term, simple_term): Add
2236 prototype to forwarded declarations. Declare parameter v1 as
2237 eval_t * instead of int *. Same for local variable v2 in dyadic
2238 functions. Same for result in exp_term.
2239 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2240 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2241 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2242 (shipout_int): Cast first argument of ntoa to eval_t.
2243 Reported by Thorsten Ohl.
2245 * macro.c: Complete the prototypes of forwarded expand_macro and
2246 expand_token.
2247 Reported by Thorsten Ohl.
2249 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2250 The Ultrix 3.1 compiler cannot do much with void pointers.
2252 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2253 * m4.c (xfree): Replace void * by voidstar.
2254 Reported by Tom McConnell.
2256 * ansi2knr.1: New, from elsewhere.
2257 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2259 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2260 stamp-h does not exist yet. This avoids running it a second time
2261 just after the initial ./configure.
2262 Reported by David MacKenzie and Tom McConnell.
2264 * m4.h: Replace the enum debug_info declaration with a series of
2265 #define's. The Ultrix 3.1 compiler would otherwise need casting
2266 (int) to most references, when used in expressions.
2267 Reported by Tom McConnell.
2269 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2271 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2272 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2273 calls the compiler. Previously, FP_PROTOTYPES was only calling
2274 the preprocessor; by not being subject to CFLAGS, this was
2275 discouraging those flags asking for ANSI compilation.
2276 * acconfig.h: Document HAVE_PROTOTYPES.
2277 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2278 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2279 Reported by Eric Backus.
2281 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2282 from the environment. Default CFLAGS to -g if not set.
2283 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2284 * lib/Makefile.in: Have CFLAGS substituted from configure.
2285 Reported by Eric Backus and Tom McConnell.
2287 * configure.in: m4_undefine changeword before using AC_ENABLE.
2289 * m4.h: Declare prototypes for error (for ANSI compilers only),
2290 prefix_all_builtins and reference_error.
2291 Reported by Tom McConnell.
2293 * input.c (set_word_regexp): Do not try to initialize the array
2294 test from a string, this does not work with non-ANSI compilers.
2295 Reported by Eric Backus.
2297 * Makefile.in (dist): Clean examples/ before saving it.
2298 (distclean-local): Also remove stamp-h.
2299 Reported by Eric Backus.
2301 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2302 non ANSI compilers.
2303 Reported by Tom McConnell.
2305 * checks/Makefile.in (clean): Depends on mostlyclean.
2306 (mostlyclean): New goal.
2308 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2310 * Makefile.in (DISTFILES): Distribute install.sh.
2311 * install.sh: New file, copied from elsewhere.
2312 Reported by Assar Westerlund and Kaveh R. Ghazi.
2314 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2316 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2317 * acconfig.h: Explain ENABLE_CHANGEWORD.
2319 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2320 from code provided by Pete Chown]
2321 * m4.h: Add original_text field to u_t variant of union u.
2322 Declare TOKEN_DATA_FUNC macro.
2323 * builtin.c: Declare changeword.
2324 (m4_changeword): New function.
2325 * input.c: Include "regex.h", define variables with word regexps.
2326 (input_init): Initialize the word regexp.
2327 (set_word_regexp): New.
2328 (next_token): Declare local variables, use the previous code if
2329 default_word_regexp is true. Else, match using a new code. Save
2330 the original text.
2331 * macro.c (expand_token): Ship out original text if not a macro
2332 name.
2333 Reported by Krste Asanovic and Pete Chown.
2335 [These modifs all depend upon ENABLE_CHANGEWORD]
2336 * m4.h: Declare external user_word_regexp.
2337 * m4.c: Declare user_word_regexp, and initialize it from
2338 --word-regexp or -W, or NULL if not specified.
2339 * input.c: Use user_word_regexp if specified, instead of
2340 DEFAULT_WORD_REGEXP.
2342 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2343 agree with it.
2345 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2346 * checks/Makefile.in: Empty the suffix list.
2347 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2349 * m4.c: Declare nesting_limit and initialize it to 250.
2350 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2351 value.
2352 * m4.h: Declare nesting_limit as external.
2353 * macro.c (expand_macro): Stop execution whenever nesting limit
2354 is exceeded.
2355 Reported by Bengt Mertensson.
2357 * eval.c (evaluate): Diagnose excess characters in eval input.
2358 Things like `eval(08)' used to return 0 with no diagnostic.
2360 * m4.h: Capitalize first letter of all macro arguments in
2361 definitions.
2363 * m4.c: Declare warning_status, initialize it to 0. Add new
2364 option -E, or --fatal-warnings, which sets warning_status to
2365 EXIT_FAILURE instead.
2366 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2367 EXIT_FAILURE if not otherwise done by header files.
2368 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2369 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2370 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2371 argument of all M4ERROR calls.
2372 Reported by Noah Friedman.
2374 * examples/incl-test.m4: Renamed from incl_test.m4.
2375 * examples/include.m4: Include incl-test.m4 instead of
2376 incl_test.m4.
2377 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2379 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2381 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2382 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2383 also tested it on a Sun Sparc workstation running SunOS 4.x.
2385 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2386 49.format check, abusing a `union values' argument with sprintf
2387 without selecting the proper field. Now, save the formatting type
2388 first, delaying the fetch of the corresponding argument.
2389 Reported by Joseph E. Sacco and Tom Quinn.
2391 * format.c (format): Remove const from char *fmt declaration when
2392 not HAVE_EFGCVT, because a NUL may be forced into it.
2394 * m4.h: Declare atof() when not STDC_HEADERS.
2395 Reported by Joseph E. Sacco.
2397 * Regenerate configure using Autoconf 1.11, this corrects a
2398 problem about an incorrect cpp seting on NeXT 3.1.
2399 Reported by Alexander Lehmann.
2401 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2403 * m4.h (_): Change argument from `x' to `Args'.
2405 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2407 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2408 bringing more evil than good on a few systems.
2409 Reported by Greg A. Woods.
2411 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2413 * m4.h: Rename Args() to _().
2414 * m4.h: Remove extern specifier from all function declarations.
2416 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
2418 * stackovf.c: New file implementing stack-overflow detection.
2419 * configure.in: Check for getrlimit, sigaction. If all of
2420 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2421 substitute ${U}stackovf.o for STACKOVF.
2422 * acconfig.h: Declare USE_STACKOVF.
2423 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2424 * m4.h: Declare setup_stackovf_trap().
2425 * m4.c: Call setup_stackovf_trap().
2426 * tests/stackovf_test.sh: New file.
2428 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2430 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2432 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2434 Sun Jan 30 14:24:19 1994 (pinard at icule)
2436 * m4.h: Remove definition of volatile, not used anymore.
2437 Reported by Jim Meyering and Joseph E. Sacco.
2439 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2440 of `if ... else /* nothing */' for if macros.
2441 Reported by Jim Meyering.
2443 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2444 warning from gcc about `repl' possibly used before defined.
2445 Reported by Jim Meyering.
2447 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2448 Reported by Jim Meyering.
2450 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2452 * m4.h: Move the conditional definition of volatile after the
2453 inclusion of system files, because they may define it first.
2455 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2457 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2458 get around a problem with Alpha make seeing a syntax error, there.
2459 Reported by Vern Paxson.
2461 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2463 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2464 Reported by Richard Stallman.
2466 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2468 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2469 instead of AC_HAVE_FUNCS.
2470 Reported by Noah Friedman.
2472 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2474 * m4.c: Initialize show_help and show_version to zero.
2476 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2477 Use them in exit() and usage() calls.
2479 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2481 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2482 syserr() macro. Delete errref, add reference_error and M4ERROR.
2483 * m4.c: Replace errref, which was returning an input reference
2484 string, with reference_error, which prints it on standard error.
2485 * builtin.c, output.c: Use errno as second parameter to error,
2486 instead of using syserr() with %s.
2487 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2488 Doing so, the program name appears after the input reference
2489 instead of before, which eases M-x next-error processing.
2491 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2493 * checks/get-them: Escape braces with backslashes in patterns,
2494 because HPUX-9.01 awk needs this.
2495 Reported by Jim Meyering.
2497 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
2499 * builtin.c: Declare "FILE *popen ();".
2501 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
2502 macros, replace error_message_prefix() declaration by errref()'s.
2503 Declare xrealloc, for use in errref().
2504 * m4.c: Delete error_message_prefix() function, add errref().
2505 * *.c: Use error() systematically in place of all error macros,
2506 now that error() flushes stdout first. Make needed adjustments.
2508 * m4.h: Remove const in sys_errlist[] declaration, it creates
2509 conflicts on SGI and Alpha.
2510 Reported by Kaveh R. Ghazi.
2512 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
2514 * m4.c: Include <getopt.h> instead of "getopt.h".

2528 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2530 * input.c (input_init): Initialize quote and comment strings
2531 explicitely instead of calling set_quotes and set_comment: by
2532 doing so, we ensure we do not free uninitialized variables.
2534 * checks/check-them: Reverse arguments to both diff, so the
2535 expected is on the left and the obtained on the right.
2537 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

2586 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
2587 Reported by Joel Sherrill.
2589 * builtin.c (prefix_all_builtins): Instead of the table size, use
2590 the null entry at end for stopping the loop. It was overwritten.
2591 Reported by Andreas Schwab and Jim Meyering.
2593 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).

2787 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
2789 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),

2821 macro.c, output.c, path.c, symtab.c: Change Copyright from
2822 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.

2839 Reported by Jason Merrill.
2840 Reported by David MacKenzie.

2848 This is still a beta release for the future GNU m4 version 1.1.
2850 * lib/alloca.c: New, from elsewhere.
2851 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2853 * m4.h: Do not define index/rindex if already defined. If
2854 FALSE/TRUE are already defined, do not redefine them, but merely
2855 define boolean typedef to int.
2857 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2858 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2859 because some C compilers do not like connectives with #ifdef.
2860 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2861 __GNUC__ and once for __STDC__.
2862 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2864 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2865 Makefile dependencies. Without it, make keeps destroying and
2866 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2868 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2869 to diversion/DIVERSION, this was a spelling error.
2871 * m4.c: Declare version[], remove #include "version.h".
2872 * version.h: Deleted.
2873 * Makefile.in: Remove references to version.h.
2875 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2876 production, by using a simpler and more robust algorithm. This
2877 solves the problem of synclines sometimes written in the middle of
2878 an output line. Delete sync_line() and output_lines variable.
2879 * m4.h: Remove sync_line prototype and output_lines declaration.
2880 * input.c (next_char), output.c (shipout_text): Remove references
2881 to output_lines.
2882 * input.c (push_file, pop_file): Merely put the value -1 in
2883 output_current_line instead of calling sync_line, for delaying a
2884 single `#line NUM FILE' before next output line. Do not test
2885 for sync_output, because this is unnecessary clutter.
2886 * output.c (make_divertion, insert_divertion): Idem.
2887 * input.c: Rename must_advance_line to start_of_input_line, for
2888 consistency.
2890 * debug.c (trace_header): Select a new debug line format, which
2891 better complies with GNU standards for formatting error messages.
2892 With option `-dfl', M-x next-error might be used on the output.
2893 * m4.c (vmesg): Adjust format of error output to GNU standards.
2894 * m4.texinfo: Adjust examples for `make check' to work.
2896 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2897 case for enum debug_info constants, which were all lower case.
2899 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2900 re_search_2.
2901 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2902 collected patches. I tried a few times using newer regex.[ch], it
2903 mysteriously stopped aborting with this one. Insecure feeling...
2904 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2906 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2908 * m4.c: Change `--no-warnings' to `--silent'.
2909 Reported by David MacKenzie.
2911 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2912 leave it off for now. See comment in m4.c for justification.
2913 Reported by David MacKenzie.
2915 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2916 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2918 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2920 * Makefile.in: Ensure recursive cleaning is done before local
2921 cleaning for all clean goals.
2923 * builtin.c (ntoa): Ensure the value is always interpreted as a
2924 signed quantity, whatever the radix is.
2926 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2928 * builtin.c, format.c, input.c: Split long lines.
2929 * m4.c: Use typedef macro_definition instead of struct
2930 macro_definition.
2931 * symtab.c: Use typedef symbol instead of struct symbol.
2933 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2935 * *.[ch]: Remove all trailing whitespace, in code and comments.
2937 * configure.in: Find some awk.
2938 * Makefile.in: Add $(AWK) to MDEFINES.
2939 * checks/Makefile.in: Transmit $(AWK) to get_them.
2940 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2941 awk script when switching files, because without this, mawk runs
2942 out of file descriptors.
2944 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2946 * Makefile.in (realclean): Delete m4.info*.
2947 Reported by Jim Meyering.
2949 * Makefile.in: Adjust and link with checks/Makefile.
2950 * checks/Makefile.in: New.
2951 * configure.in: Output checks/Makefile.
2953 * checks/get_them: Have the dnl header of each test more
2954 recognizable by next-error, also use a better message.
2956 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2958 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2959 And use that only if __GNUC__ since we're using it's GCC-specific
2960 semantics that tell the compiler the associated function doesn't
2961 return.
2963 * builtin.c (substitute): Don't use character as an array index.
2964 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2965 warnings with gcc -W -Wall on systems with qsort prototype.
2966 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2967 from gcc -W -Wall.
2969 * eval.c (most functions): Add parentheses to assignments used
2970 as truth values go avoid warnings from gcc -Wall.
2972 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2973 any functions that don't need external scope.
2975 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2976 (many functions and arrays): Declare `const'.
2978 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2980 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2981 removing the declaration from m4.h. Also rename false to FALSE
2982 and true to TRUE.
2984 * lib/Makefile.in (Makefile): New goal.
2986 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2987 so heavily loaded. It gets more easily overridable, calling make.
2988 Reported by Jim Meyering.
2990 * Makefile.in (dist): Get .fname from the current directory name,
2991 instead of from version.h. I need updating many files manually,
2992 when the version changes, version.h is just one of them.
2994 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2996 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2997 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2998 Reported by Tom McConnell.
3000 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3002 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3003 39.cleardiv, which were describing missing or spurious newlines.
3004 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3005 do not depend on machine word size, `/bin/false' implementation,
3006 or `wc' output format. `make check' is more dependable, now.
3008 * checks/check_them: Summarize the failed tests by listing their
3009 name, at end. If none, issue `All checks successful'. Output
3010 `Checking' instead of `Input file:'.
3012 * checks/get_them, checks/check_them: Reindented.
3014 * Makefile.in (dist): chmod a+r before making the tar file.
3016 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3018 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3020 * input.c (next_token): Reinitialize token_buttom just after using
3021 it as a watermark with obstack_free. Or else, a future token, big
3022 enough for triggering reallocation of the obstack chunk, could
3023 void the initialized value of token_buttom, later causing panic in
3024 obstack_free. Rename token_buttom to token_bottom everywhere.
3026 * m4.h: Before declaring errno, first include <errno.h> and
3027 ensure that it does not define errno.
3028 Reported by Richard Stallman.
