1106 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1107 empty file rather than to a nonexistent file. This closes a common
1109 * src/builtin.c (m4_maketemp): Implement the above, by using
1110 mkstemp rather than mktemp. (trivial change)
1112 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1114 * src/builtin.c (expand_ranges): Added break after trailing dash.

1127 be opened, return immediately after producing the error message.
1128 Reported by Andreas Schwab.
1130 * configure.in: Check for const only after having found possible
1131 ANSIfying compiler flags, this is of no use to check it before.

1159 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1160 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1161 defines __STDC__ to 0, for indicating it is *not* ANSI!
1162 Reported by Kaveh R. Ghazi.

1178 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1179 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1180 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1181 of $U, put underline in extensions rather than in basenames. Use
1182 implicit rules, now that regularity makes this possible.
1183 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1184 of ansi2knr whenever it is needed.
1185 * configure.in: Adjusted for correct STACKOVF substitution.
1186 * src/debug.c (trace_format): When not __STDC__, use (...) as a

1205 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1207 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

1281 a subshell for each recursive $(MAKE).
1282 Reported by Jim Meyering.
1284 * src/m4.h (memcpy): Define with bcopy for BSD systems.
1285 Reported by Kaveh R. Ghazi.
1287 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1288 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1291 * configure.in: Use date instead of touch for stamp-h.
1292 * Makefile.in (stamp-h.in): Idem.
1294 * Makefile.in (distclean, realclean): Force serial execution of

1347 calling a function by that name. Declare the variable.
1348 * src/m4.h: Adjust declaration for prefix_all_buitins.
1349 * src/builtin.c (builtin_init): Merge in functionality from
1350 previous prefix_all_buitins function, while making entries in the
1351 symbol table, but not modifying the builtin description itself.
1353 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1354 because *many* compilers do not accept an empty `default:'.
1355 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1356 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1358 * configure.in: Use AC_TYPE_SIGNAL.
1359 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.

1379 * Makefile.in: Adjusted.
1380 * configure.in: Configure new Makefiles.
1382 * m4.h: Declare STRING typedef. Use it for comment and quote
1383 strings, adjusting all references. (This is the rudiments of a

1385 * output.c (shipout_text): Accept a length parameter, and use it.
1386 All callers adjusted.
1388 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)

1411 * m4.h: Declare freeze_diversions.
1412 * freeze.c: Document frozen file format, revise it, call
1413 freeze_diversions to add diversions to frozen format, and code to
1414 reload them properly.
1415 * m4.c: Do not undivert automatically at end when status being
1416 frozen. Do not call builtin_init when reloading frozen state.
1418 Speed up diversion processing:
1419 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
1420 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
1421 structure and variables, cached variables out of output_diversion,
1422 reallocate_diversion_for and OUTPUT_CHARACTER.
1423 (shipout_text, make_diversion, insert_diversion): Adapted to new

1433 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
1435 * symtab.c (hack_all_symbols): Use hash_table_size instead of
1436 constant HASHMAX, for -H option to work better.
1438 * builtin.c (DECLARE): Simplify by using _ ().
1440 * freeze.c: New file.
1441 * Makefile.in: Compile it, distribute it.
1442 * m4.c: Recognize, document and process --freeze-state (-F) and
1443 --reload-state (-R) options. Pass a true flag to builtin_init
1444 only if no reloading some state.
1445 * builtin.c (define_builtin): Remove static specifier.
1446 (find_builtin_by_name): Remove static specifier.
1447 (builtin_init): Accept and obey a flag argument.

1510 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
1512 * configure.in: Check for sigaction and sigvec. Add a new delayed
1513 check for RLIMIT_STACK, combine in the checking for getrlimit.
1514 All those things are not universally available.
1515 * stackovf.c: Split setting up the trap handler and catching
1516 signals, for better taking care of various configure outcomes.
1517 * examples/stackovf.sh: Correct a typo.
1518 Reported by Eric Backus, Jim Avera and Jim Meyering.

1528 Reported by Jim Meyering.
1530 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
1532 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
1533 error message, for when no code possibility exists. Even if this
1534 line is completely #ifdef'ed out, it brings a syntax error.
1535 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
1537 * Makefile.in (install): Have install depend on all too, for lib
1538 to be remade as needed.
1540 * examples/stackovf.sh: Try ksh, bsh and bash for shells

1544 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
1546 * Makefile.in (check): Have it depend on all instead of m4. In
1547 this way, a change in lib will be detected and processed.
1549 * builtin.c (numeric_arg): Use strtol and verify the conversion,
1550 instead of using sscanf which stops as soon as there is a
1551 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
1552 and divert(1xyzzy) were all accepted without any warning or error
1554 * m4.h: Declare strtol as long if not including stdlib.h.
1555 * configure.in: Check for limits.h, and replace strtol if missing.
1556 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
1557 * lib/strtol.c: New file, from elsewhere.

1567 Reported by Jim Meyering.
1569 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
1571 * stackovf.c: Isolated OS-dependent sections; Improved portability,
1572 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
1573 handlers), and a default error message if the fault address is not
1574 available (when neither siginfo.h nor BSD sigcontext are supported).
1575 * configure.in: Changes for stackovf.h: Check for sigcontext,
1576 sigaction, sigstack, and define rlim_t as int if necessary.
1577 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
1578 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.

1581 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
1583 * configure.in: Use AC_SET_MAKE.
1584 * Makefile.in: Use @SET_MAKE@.
1585 Reported by Jim Meyering.

1588 Reported by Ian Taylor.
1590 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
1592 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
1593 because siginfo.h is unrelated to standard headers, and siginfo.h
1594 is already checked for.
1595 Reported by Joseph E. Sacco.
1597 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
1599 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
1602 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
1604 * builtin.c (substitute): Use \& to represent this part of the
1605 string which was matched by the whole regexp, instead of
1606 representing the whole string. Any usage of \0 issues a warning
1607 and acts like \&, it will disappear in some subsequent release.
1609 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
1611 * m4.c: Complete prototype for forwarded declaration of usage.
1613 * input.c (init_macro_token): Correct own reference in error
1614 message. Previous name get_macro_func was referred to instead.
1615 (next_char): Correct own reference in error message. Previous
1616 name advance_input was referred to instead.
1618 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
1619 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
1620 and_term, not_term, logical_not_term, cmp_term, shift_term,
1621 add_term, mult_term, exp_term, unary_term, simple_term): Add
1622 prototype to forwarded declarations. Declare parameter v1 as
1623 eval_t * instead of int *. Same for local variable v2 in dyadic
1624 functions. Same for result in exp_term.
1625 * builtin.c (m4_eval): Declare value as eval_t instead of int.
1626 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
1627 unsigned_eval_t instead of unsigned int. Change casts accordingly.
1628 (shipout_int): Cast first argument of ntoa to eval_t.
1629 Reported by Thorsten Ohl.
1631 * macro.c: Complete the prototypes of forwarded expand_macro and
1633 Reported by Thorsten Ohl.
1635 * m4.h: Define voidstar as void * or char * depending on __STDC__.
1636 The Ultrix 3.1 compiler cannot do much with void pointers.
1638 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
1639 * m4.c (xfree): Replace void * by voidstar.
1640 Reported by Tom McConnell.
1642 * ansi2knr.1: New, from elsewhere.
1643 * Makefile.in (DISTFILES): Distribute ansi2knr.1
1645 * Makefile.in (stamp-h.in): Avoid running ./config.status if
1646 stamp-h does not exist yet. This avoids running it a second time
1647 just after the initial ./configure.
1648 Reported by David MacKenzie and Tom McConnell.
1650 * m4.h: Replace the enum debug_info declaration with a series of
1651 #define's. The Ultrix 3.1 compiler would otherwise need casting
1652 (int) to most references, when used in expressions.
1653 Reported by Tom McConnell.
1655 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
1657 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
1658 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
1659 calls the compiler. Previously, FP_PROTOTYPES was only calling
1660 the preprocessor; by not being subject to CFLAGS, this was
1661 discouraging those flags asking for ANSI compilation.
1662 * acconfig.h: Document HAVE_PROTOTYPES.
1663 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
1664 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
1665 Reported by Eric Backus.
1667 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
1668 from the environment. Default CFLAGS to -g if not set.
1669 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
1670 * lib/Makefile.in: Have CFLAGS substituted from configure.
1671 Reported by Eric Backus and Tom McConnell.
1673 * configure.in: m4_undefine changeword before using AC_ENABLE.
1675 * m4.h: Declare prototypes for error (for ANSI compilers only),
1676 prefix_all_builtins and reference_error.
1677 Reported by Tom McConnell.
1679 * input.c (set_word_regexp): Do not try to initialize the array
1680 test from a string, this does not work with non-ANSI compilers.
1681 Reported by Eric Backus.
1683 * Makefile.in (dist): Clean examples/ before saving it.
1684 (distclean-local): Also remove stamp-h.
1685 Reported by Eric Backus.
1687 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
1689 Reported by Tom McConnell.
1691 * checks/Makefile.in (clean): Depends on mostlyclean.
1692 (mostlyclean): New goal.

1696 * Makefile.in (DISTFILES): Distribute install.sh.
1697 * install.sh: New file, copied from elsewhere.
1698 Reported by Assar Westerlund and Kaveh R. Ghazi.

1702 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
1703 * acconfig.h: Explain ENABLE_CHANGEWORD.
1705 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
1706 from code provided by Pete Chown]
1707 * m4.h: Add original_text field to u_t variant of union u.
1708 Declare TOKEN_DATA_FUNC macro.
1709 * builtin.c: Declare changeword.
1710 (m4_changeword): New function.
1711 * input.c: Include "regex.h", define variables with word regexps.
1712 (input_init): Initialize the word regexp.
1713 (set_word_regexp): New.
1714 (next_token): Declare local variables, use the previous code if
1715 default_word_regexp is true. Else, match using a new code. Save
1717 * macro.c (expand_token): Ship out original text if not a macro
1719 Reported by Krste Asanovic and Pete Chown.
1721 [These modifs all depend upon ENABLE_CHANGEWORD]
1722 * m4.h: Declare external user_word_regexp.
1723 * m4.c: Declare user_word_regexp, and initialize it from
1724 --word-regexp or -W, or NULL if not specified.
1725 * input.c: Use user_word_regexp if specified, instead of
1726 DEFAULT_WORD_REGEXP.
1728 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
1731 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
1732 * checks/Makefile.in: Empty the suffix list.
1733 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.

1736 Implement -LNUMBER or --nesting-limit=NUMBER to change its
1738 * m4.h: Declare nesting_limit as external.
1739 * macro.c (expand_macro): Stop execution whenever nesting limit
1741 Reported by Bengt Mertensson.
1743 * eval.c (evaluate): Diagnose excess characters in eval input.
1744 Things like `eval(08)' used to return 0 with no diagnostic.
1746 * m4.h: Capitalize first letter of all macro arguments in
1749 * m4.c: Declare warning_status, initialize it to 0. Add new
1750 option -E, or --fatal-warnings, which sets warning_status to
1751 EXIT_FAILURE instead.
1752 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
1753 EXIT_FAILURE if not otherwise done by header files.
1754 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
1755 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
1756 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
1757 argument of all M4ERROR calls.
1758 Reported by Noah Friedman.
1760 * examples/incl-test.m4: Renamed from incl_test.m4.
1761 * examples/include.m4: Include incl-test.m4 instead of
1763 * examples/multiquotes.m4: Renamed from multi-quotes.m.
1765 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
1767 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
1768 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
1769 also tested it on a Sun Sparc workstation running SunOS 4.x.
1771 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
1772 49.format check, abusing a `union values' argument with sprintf
1773 without selecting the proper field. Now, save the formatting type
1774 first, delaying the fetch of the corresponding argument.
1775 Reported by Joseph E. Sacco and Tom Quinn.
1777 * format.c (format): Remove const from char *fmt declaration when
1778 not HAVE_EFGCVT, because a NUL may be forced into it.
1780 * m4.h: Declare atof() when not STDC_HEADERS.
1781 Reported by Joseph E. Sacco.
1783 * Regenerate configure using Autoconf 1.11, this corrects a
1784 problem about an incorrect cpp seting on NeXT 3.1.
1785 Reported by Alexander Lehmann.
1787 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
1789 * m4.h (_): Change argument from `x' to `Args'.
1791 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
1793 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
1794 bringing more evil than good on a few systems.
1795 Reported by Greg A. Woods.

1807 substitute ${U}stackovf.o for STACKOVF.
1808 * acconfig.h: Declare USE_STACKOVF.
1809 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
1810 * m4.h: Declare setup_stackovf_trap().
1811 * m4.c: Call setup_stackovf_trap().
1812 * tests/stackovf_test.sh: New file.

1816 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
1818 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
1820 Sun Jan 30 14:24:19 1994 (pinard at icule)
1822 * m4.h: Remove definition of volatile, not used anymore.
1823 Reported by Jim Meyering and Joseph E. Sacco.
1825 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
1826 of `if ... else /* nothing */' for if macros.
1827 Reported by Jim Meyering.
1829 * builtin.c (m4_regexp): Reorganize the code for avoiding a
1830 warning from gcc about `repl' possibly used before defined.
1831 Reported by Jim Meyering.
1833 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
1834 Reported by Jim Meyering.
1836 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
1838 * m4.h: Move the conditional definition of volatile after the
1839 inclusion of system files, because they may define it first.
1841 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
1843 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
1844 get around a problem with Alpha make seeing a syntax error, there.
1845 Reported by Vern Paxson.
1847 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
1849 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
1850 Reported by Richard Stallman.
1852 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)

1855 instead of AC_HAVE_FUNCS.
1856 Reported by Noah Friedman.
1858 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
1860 * m4.c: Initialize show_help and show_version to zero.
1862 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
1863 Use them in exit() and usage() calls.
1865 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
1867 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
1868 syserr() macro. Delete errref, add reference_error and M4ERROR.
1869 * m4.c: Replace errref, which was returning an input reference
1870 string, with reference_error, which prints it on standard error.
1871 * builtin.c, output.c: Use errno as second parameter to error,
1872 instead of using syserr() with %s.
1873 * *.c: Use M4ERROR instead of error: no more errref() with %s.
1874 Doing so, the program name appears after the input reference
1875 instead of before, which eases M-x next-error processing.
1877 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
1879 * checks/get-them: Escape braces with backslashes in patterns,
1880 because HPUX-9.01 awk needs this.

1889 Declare xrealloc, for use in errref().
1890 * m4.c: Delete error_message_prefix() function, add errref().
1891 * *.c: Use error() systematically in place of all error macros,
1892 now that error() flushes stdout first. Make needed adjustments.
1894 * m4.h: Remove const in sys_errlist[] declaration, it creates
1895 conflicts on SGI and Alpha.
1896 Reported by Kaveh R. Ghazi.
1898 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

1914 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
1916 * input.c (input_init): Initialize quote and comment strings
1917 explicitely instead of calling set_quotes and set_comment: by
1918 doing so, we ensure we do not free uninitialized variables.
1920 * checks/check-them: Reverse arguments to both diff, so the
1921 expected is on the left and the obtained on the right.
1923 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
1924 macros. Delete declarations for m4error, warning, fatal and
1925 internal_error, add declaration for error_message_prefix.
1926 * m4.c: Delete m4error, warning, fatal and internal_error
1927 routines, add error_message_prefix routine.
1928 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
1929 warning with WARNING*, fatal with FATAL* and internal_error with
1931 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
1932 this is not needed anymore.
1934 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
1935 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
1936 and debug_message, add declaration for debug_message_prefix.

1938 Delete debug_print and debug_message routines, add
1939 debug_message_prefix routine.
1940 * builtin.c, debug.c: Replace debug_print routine calls with
1941 DEBUG_PRINT* macro calls.

1947 (trace_format): Use stdarg instead of varargs if __STDC__.
1949 * configure.in: Remove checks for vfprintf and _doprnt. These
1950 implementations use varargs tricks which are not portable enough.
1951 * lib/vfprintf.c: Deleted.
1952 * lib/_doprnt.c: Deleted.
1953 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
1954 Reported by Joel Sherrill.

1973 Reported by Joel Sherrill.
1975 * builtin.c (prefix_all_builtins): Instead of the table size, use
1976 the null entry at end for stopping the loop. It was overwritten.
1977 Reported by Andreas Schwab and Jim Meyering.
1979 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
1980 Reported by Kaveh R. Ghazi.

2167 Sat Feb 6 14:59:22 1993 Francois Pinard (pinard@icule)
2169 * Makefile.in, lib/Makefile.in, check/Makefile.in: In dist goals,

2173 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
2175 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
2176 so the installer can override automatically configured choices.
2177 Reported by Karl Berry.
2179 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
2181 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The
2182 previous version was not working properly on m68k-hp-bsd4.3.
2183 Reported by Roland McGrath.
2185 * lib/_doprnt.c: Stolen from Oleo distribution.
2186 * configure.in: Check for _doprnt.c if vfprintf.c selected.

2188 Do not distribute regex.[ch].old anymore.
2190 Fri Jan 1 19:42:23 1993 Francois Pinard (pinard at icule)
2192 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
2193 Richard wants it there.

2197 * Makefile.in: Add DEFS to MDEFINES.
2198 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
2199 (libm4.a): Remove the library before creating it.
2200 (distclean): Remove tags and TAGS too.
2202 Wed Dec 23 12:46:55 1992 Francois Pinard (pinard at icule)
2204 * Makefile.in (dvi, m4.dvi): New goals.
2206 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
2207 macro.c, output.c, path.c, symtab.c: Change Copyright from
2208 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
2210 * examples/divert.m4: Deleted, this bug has been corrected.
2212 * Makefile.in (texclean, mostlyclean): New goals.
2214 * Makefile.in (clean): Remove clutter from ansi2knr.
2215 Reported by Pierre Gaumond.
2216 Reported by Greg A. Woods.
2218 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
2220 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
2221 might well use CFLAGS is s/he needs it.
2223 * Makefile.in: Allow installation of info files from a separate

2226 Reported by David MacKenzie.
2227 Reported by Skip Montanaro.

2231 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
2234 This is still a beta release for the future GNU m4 version 1.1.
2236 * lib/alloca.c: New, from elsewhere.
2237 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2239 * m4.h: Do not define index/rindex if already defined. If
2240 FALSE/TRUE are already defined, do not redefine them, but merely
2241 define boolean typedef to int.
2243 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2244 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2245 because some C compilers do not like connectives with #ifdef.
2246 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2247 __GNUC__ and once for __STDC__.
2248 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2250 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2251 Makefile dependencies. Without it, make keeps destroying and
2252 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2254 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2255 to diversion/DIVERSION, this was a spelling error.
2257 * m4.c: Declare version[], remove #include "version.h".
2258 * version.h: Deleted.
2259 * Makefile.in: Remove references to version.h.
2261 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2262 production, by using a simpler and more robust algorithm. This
2263 solves the problem of synclines sometimes written in the middle of
2264 an output line. Delete sync_line() and output_lines variable.
2265 * m4.h: Remove sync_line prototype and output_lines declaration.
2266 * input.c (next_char), output.c (shipout_text): Remove references
2268 * input.c (push_file, pop_file): Merely put the value -1 in
2269 output_current_line instead of calling sync_line, for delaying a
2270 single `#line NUM FILE' before next output line. Do not test
2271 for sync_output, because this is unnecessary clutter.
2272 * output.c (make_divertion, insert_divertion): Idem.
2273 * input.c: Rename must_advance_line to start_of_input_line, for
2276 * debug.c (trace_header): Select a new debug line format, which
2277 better complies with GNU standards for formatting error messages.
2278 With option `-dfl', M-x next-error might be used on the output.
2279 * m4.c (vmesg): Adjust format of error output to GNU standards.
2280 * m4.texinfo: Adjust examples for `make check' to work.
2282 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2283 case for enum debug_info constants, which were all lower case.
2285 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2287 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2288 collected patches. I tried a few times using newer regex.[ch], it
2289 mysteriously stopped aborting with this one. Insecure feeling...
2290 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2292 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2294 * m4.c: Change `--no-warnings' to `--silent'.
2295 Reported by David MacKenzie.
2297 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2298 leave it off for now. See comment in m4.c for justification.
2299 Reported by David MacKenzie.
2301 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2302 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2304 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2306 * Makefile.in: Ensure recursive cleaning is done before local
2307 cleaning for all clean goals.
2309 * builtin.c (ntoa): Ensure the value is always interpreted as a
2310 signed quantity, whatever the radix is.
2312 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2314 * builtin.c, format.c, input.c: Split long lines.
2315 * m4.c: Use typedef macro_definition instead of struct
2317 * symtab.c: Use typedef symbol instead of struct symbol.
2319 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2321 * *.[ch]: Remove all trailing whitespace, in code and comments.
2323 * configure.in: Find some awk.
2324 * Makefile.in: Add $(AWK) to MDEFINES.
2325 * checks/Makefile.in: Transmit $(AWK) to get_them.
2326 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2327 awk script when switching files, because without this, mawk runs
2328 out of file descriptors.
2330 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2332 * Makefile.in (realclean): Delete m4.info*.
2333 Reported by Jim Meyering.
2335 * Makefile.in: Adjust and link with checks/Makefile.
2336 * checks/Makefile.in: New.
2337 * configure.in: Output checks/Makefile.
2339 * checks/get_them: Have the dnl header of each test more
2340 recognizable by next-error, also use a better message.
2342 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2344 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2345 And use that only if __GNUC__ since we're using it's GCC-specific
2346 semantics that tell the compiler the associated function doesn't
2349 * builtin.c (substitute): Don't use character as an array index.
2350 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2351 warnings with gcc -W -Wall on systems with qsort prototype.
2352 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2355 * eval.c (most functions): Add parentheses to assignments used
2356 as truth values go avoid warnings from gcc -Wall.
2358 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2359 any functions that don't need external scope.
2361 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2362 (many functions and arrays): Declare `const'.
2364 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2366 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2367 removing the declaration from m4.h. Also rename false to FALSE
2370 * lib/Makefile.in (Makefile): New goal.
2372 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2373 so heavily loaded. It gets more easily overridable, calling make.
2374 Reported by Jim Meyering.
2376 * Makefile.in (dist): Get .fname from the current directory name,
2377 instead of from version.h. I need updating many files manually,
2378 when the version changes, version.h is just one of them.
2380 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2382 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2383 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2384 Reported by Tom McConnell.
2386 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2388 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2389 39.cleardiv, which were describing missing or spurious newlines.
2390 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2391 do not depend on machine word size, `/bin/false' implementation,
2392 or `wc' output format. `make check' is more dependable, now.
2394 * checks/check_them: Summarize the failed tests by listing their
2395 name, at end. If none, issue `All checks successful'. Output
2396 `Checking' instead of `Input file:'.
2398 * checks/get_them, checks/check_them: Reindented.
2400 * Makefile.in (dist): chmod a+r before making the tar file.
2402 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2404 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2406 * input.c (next_token): Reinitialize token_buttom just after using
2407 it as a watermark with obstack_free. Or else, a future token, big
2408 enough for triggering reallocation of the obstack chunk, could
2409 void the initialized value of token_buttom, later causing panic in
2410 obstack_free. Rename token_buttom to token_bottom everywhere.
2412 * m4.h: Before declaring errno, first include <errno.h> and
2413 ensure that it does not define errno.
2414 Reported by Richard Stallman.
2416 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
2418 * builtin.c: Define and use DECLARE macro for builtins.
2420 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
2421 argument, this is a common idiom for introducing long comments.
2423 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
2424 arguments. The last argument was silently ignored.
2426 * m4.c (cmd_error): Add a missing semicolon before va_end().
2428 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
2430 * Makefile.in: Now handle protoized sources. Define and use U.
2431 Compile and use ansi2knr with old compilers. Update DISTFILES.
2432 Add `aclocal.m4' to `configure' dependencies.
2433 * ansi2knr.c: New, from Ghostscript distribution.
2434 * configure.in: Define U through FP_PROTOTYPES for old compilers.
2435 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
2436 * aclocal.m4: New, provide FP_PROTOTYPES.
2437 * m4.h: Conditionnaly protoized through Args, save for varags.
2438 * builtin.c: Protoized. Then:
2439 Include <sys/types.h> if size_t is not defined, before "regex.h".
2440 (m4_ifelse): Fetch built-in name properly for diagnostic.
2441 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
2442 (m4_regexp): Add const to `msg' declaration.
2443 (m4_patsubst): Add const to `msg' declaration.
2444 * debug.c: Protoized, save for varargs.
2445 * eval.c: Protoized.
2446 * format.c: Protoized.
2447 * input.c: Protoized.
2448 * m4.c: Protoized, save for varargs. Then:
2449 (xfree): Accept void * instead of char *.
2450 (xmalloc): Return void * instead of char *.
2451 (xrealloc): Accept and return void * instead of char *.
2452 * macro.c: Protoized.
2453 * output.c: Protoized.
2454 * path.c: Protoized. Then cast some (char *) over xmalloc's.
2455 * symtab.c: Protoized.
2457 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
2459 * m4.texinfo: Remove directory from diagnostics in 30.include,
2460 51.eval, 56.errprint and 57.m4exit tests.
2462 * m4.h: Remove declarations for int or void system functions, they
2463 cause more conflicting trouble than they make good.
2465 * configure.in: Avoid configuration header file. Add some tests.
2466 * m4.h: Remove #include "config.h".
2467 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
2468 Then, rewritten for better compliance with GNU standards.
2470 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
2472 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
2473 because of a misplaced #endif.
2475 * Many *.[hc] files: Correct intra-line spacing here and there,
2476 according to GNU indent 1.6 advice.
2478 * configure.in: New, using Autoconf 1.2.
2479 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.

2489 * version.h: De-automatize, force value in.
2491 * m4.c: Changes in order to use a newer getopt.h.
2492 Reported by David MacKenzie.
2494 * checks/: New name for examples/.
2495 * checks/get_them: New location for etc/get_examples.
2496 * checks/check_them: New location for etc/check_examples.

2504 * Makefile.in (check): Add m4 as dependency.
2506 * m4.c: Accept --no-warnings instead of --no_warnings, and
2507 --no-gnu-extensions instead of --no_gnu_extensions. Make the
2508 usage message more informative.
2509 Reported by David MacKenzie.

2525 Reported by Richard Stallman.
2527 * config/hmake-unicos, config/s-unicos.h: New files.
2528 Reported by Hal Peterson.
2530 * eval.c (exp_term): Have N^0 return 1.
2531 Reported by Michael Fetterman.
2533 * eval.c, input.c, m4.h: Remove last comma in enums.
2534 Reported by Mike Lijewski.

2552 * The built-in format can now be configured to use sprintf as
2553 the formatting engine, for systems without [efg]cvt(3).
