905 2005-02-03 Gary V. Vaughan <gary@gnu.org>

1023 empty file rather than to a nonexistent file. This closes a common
1024 security hole.
1025 * src/builtin.c (m4_maketemp): Implement the above, by using
1026 mkstemp rather than mktemp. (trivial change)
1028 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1030 * src/builtin.c (expand_ranges): Added break after trailing dash.

1035 * Release 1.4.
1037 * doc/Makefile.in (realclean): Also remove stamp-vti.

1043 be opened, return immediately after producing the error message.
1044 Reported by Andreas Schwab.
1046 * configure.in: Check for const only after having found possible
1047 ANSIfying compiler flags, this is of no use to check it before.
1048 Reported by Alexander Lehmann.
1050 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
1052 * src/macro.c (collect_arguments): Cast obstack arguments to
1053 (voidstar), so avoiding compiler warnings.
1054 Reported by Joseph E. Sacco.

1075 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1076 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1077 defines __STDC__ to 0, for indicating it is *not* ANSI!
1078 Reported by Kaveh R. Ghazi.
1080 * configure.in: Added obsolescent tests for AIX and Minix.
1082 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,

1094 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1095 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1096 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1097 of $U, put underline in extensions rather than in basenames. Use
1098 implicit rules, now that regularity makes this possible.
1099 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1100 of ansi2knr whenever it is needed.
1101 * configure.in: Adjusted for correct STACKOVF substitution.
1102 * src/debug.c (trace_format): When not __STDC__, use (...) as a
1103 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
1104 Reported by David MacKenzie.
1106 * Makefile.in: Remove binprefix. Use transform_name instead.
1107 Reported by David MacKenzie.

1114 * Makefile.in (all, install, uninstall): Depend on Makefile.
1116 * Makefile.in: For actions invoking $(MAKE) from within compound

1187 calling $(MAKE) for the -local part, allow parallel execution of
1188 -recursive and -local, only delay the removal of config.status,
1189 which is repeated in both goals.
1190 \f

1193 * Release 1.3.
1195 * Makefile.in: Group all *clean-recursive goals in one, using sed
1196 to remove `-recursive' while calling make recursively. Also, use

1200 * src/m4.h (memcpy): Define with bcopy for BSD systems.
1201 Reported by Kaveh R. Ghazi.
1203 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1204 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1205 specify it.
1207 * configure.in: Use date instead of touch for stamp-h.
1208 * Makefile.in (stamp-h.in): Idem.
1210 * Makefile.in (distclean, realclean): Force serial execution of

1238 Reported by Jim Meyering.
1240 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)
1242 * configure.in: Correct stack overflow detection logic, taking
1243 care of systems having only incomplete implementations (like for
1244 Pyramid 9820 OSx 5.0d).
1245 Reported by Kaveh R. Ghazi.
1247 * src/Makefile.in (TAGS): Remote -t from etags call.
1249 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)

1259 Reported by Jim Meyering.
1261 Solidify frozen files with respect to -P:
1262 * src/m4.c: Have -P set prefix_all_buitins variable instead of
1263 calling a function by that name. Declare the variable.
1264 * src/m4.h: Adjust declaration for prefix_all_buitins.
1265 * src/builtin.c (builtin_init): Merge in functionality from
1266 previous prefix_all_buitins function, while making entries in the
1267 symbol table, but not modifying the builtin description itself.
1269 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1270 because *many* compilers do not accept an empty `default:'.
1271 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1272 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1274 * configure.in: Use AC_TYPE_SIGNAL.
1275 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
1276 Reported by Robert Bernstein.
1278 * checks/Makefile.in (check): Modify PATH so check-them will find
1279 m4 in the src directory.
1280 * Makefile.in (check): Don't.
1281 Reported by Akiko Matsushita and Jim Meyering.
1283 * src/output.c (make_room_for, output_character_helper): New
1284 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
1285 a per buffer MAXIMUM_BUFFER_SIZE.
1287 * src/output.c (output_text): New function, for optimizing the

1292 * doc, src: New directories reorganizing the distribution.
1293 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
1294 files.
1295 * Makefile.in: Adjusted.
1296 * configure.in: Configure new Makefiles.
1298 * m4.h: Declare STRING typedef. Use it for comment and quote
1299 strings, adjusting all references. (This is the rudiments of a
1300 beginning for the eventual withdrawal of NUL terminated strings.)
1301 * output.c (shipout_text): Accept a length parameter, and use it.
1302 All callers adjusted.
1304 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)

1326 * output.c (freeze_diversions): New function.
1327 * m4.h: Declare freeze_diversions.

1332 frozen. Do not call builtin_init when reloading frozen state.
1334 Speed up diversion processing:
1335 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
1336 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
1337 structure and variables, cached variables out of output_diversion,
1338 reallocate_diversion_for and OUTPUT_CHARACTER.
1339 (shipout_text, make_diversion, insert_diversion): Adapted to new
1340 structures.
1341 (insert_file): Use better buffering.
1342 Reported by David MacKenzie.
1344 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
1346 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
1347 dist works from another build directory.
1349 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
1351 * symtab.c (hack_all_symbols): Use hash_table_size instead of
1352 constant HASHMAX, for -H option to work better.
1354 * builtin.c (DECLARE): Simplify by using _ ().
1356 * freeze.c: New file.
1357 * Makefile.in: Compile it, distribute it.
1358 * m4.c: Recognize, document and process --freeze-state (-F) and
1359 --reload-state (-R) options. Pass a true flag to builtin_init
1360 only if no reloading some state.
1361 * builtin.c (define_builtin): Remove static specifier.

1426 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
1428 * configure.in: Check for sigaction and sigvec. Add a new delayed
1429 check for RLIMIT_STACK, combine in the checking for getrlimit.
1430 All those things are not universally available.
1431 * stackovf.c: Split setting up the trap handler and catching
1432 signals, for better taking care of various configure outcomes.
1433 * examples/stackovf.sh: Correct a typo.
1434 Reported by Eric Backus, Jim Avera and Jim Meyering.
1436 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)

1444 Reported by Jim Meyering.
1446 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
1448 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
1449 error message, for when no code possibility exists. Even if this
1450 line is completely #ifdef'ed out, it brings a syntax error.
1451 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
1453 * Makefile.in (install): Have install depend on all too, for lib
1454 to be remade as needed.

1460 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
1462 * Makefile.in (check): Have it depend on all instead of m4. In
1463 this way, a change in lib will be detected and processed.
1465 * builtin.c (numeric_arg): Use strtol and verify the conversion,
1466 instead of using sscanf which stops as soon as there is a
1467 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
1468 and divert(1xyzzy) were all accepted without any warning or error
1469 messages.
1470 * m4.h: Declare strtol as long if not including stdlib.h.
1471 * configure.in: Check for limits.h, and replace strtol if missing.
1472 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
1473 * lib/strtol.c: New file, from elsewhere.
1474 Reported by Andreas Schwab.

1479 assigning it to traced.
1480 Reported by Tom McConnell.
1482 * Makefile.in (m4): Always make all in lib first.
1483 Reported by Jim Meyering.
1485 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
1487 * stackovf.c: Isolated OS-dependent sections; Improved portability,
1488 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
1489 handlers), and a default error message if the fault address is not
1490 available (when neither siginfo.h nor BSD sigcontext are supported).
1491 * configure.in: Changes for stackovf.h: Check for sigcontext,
1492 sigaction, sigstack, and define rlim_t as int if necessary.
1493 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
1494 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
1495 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
1497 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
1499 * configure.in: Use AC_SET_MAKE.
1500 * Makefile.in: Use @SET_MAKE@.
1501 Reported by Jim Meyering.
1503 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
1504 Reported by Ian Taylor.
1506 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
1508 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
1509 because siginfo.h is unrelated to standard headers, and siginfo.h
1510 is already checked for.
1511 Reported by Joseph E. Sacco.
1513 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
1514 PROTOTYPES.
1515 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
1516 AC_PROTOTYPES.
1518 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
1520 * builtin.c (substitute): Use \& to represent this part of the
1521 string which was matched by the whole regexp, instead of
1522 representing the whole string. Any usage of \0 issues a warning
1523 and acts like \&, it will disappear in some subsequent release.
1525 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
1527 * m4.c: Complete prototype for forwarded declaration of usage.
1529 * input.c (init_macro_token): Correct own reference in error
1530 message. Previous name get_macro_func was referred to instead.
1531 (next_char): Correct own reference in error message. Previous
1532 name advance_input was referred to instead.
1534 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
1535 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
1536 and_term, not_term, logical_not_term, cmp_term, shift_term,
1537 add_term, mult_term, exp_term, unary_term, simple_term): Add
1538 prototype to forwarded declarations. Declare parameter v1 as
1539 eval_t * instead of int *. Same for local variable v2 in dyadic
1540 functions. Same for result in exp_term.
1541 * builtin.c (m4_eval): Declare value as eval_t instead of int.
1542 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
1543 unsigned_eval_t instead of unsigned int. Change casts accordingly.
1544 (shipout_int): Cast first argument of ntoa to eval_t.
1545 Reported by Thorsten Ohl.
1547 * macro.c: Complete the prototypes of forwarded expand_macro and
1548 expand_token.
1549 Reported by Thorsten Ohl.
1551 * m4.h: Define voidstar as void * or char * depending on __STDC__.
1552 The Ultrix 3.1 compiler cannot do much with void pointers.
1554 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
1555 * m4.c (xfree): Replace void * by voidstar.
1556 Reported by Tom McConnell.
1558 * ansi2knr.1: New, from elsewhere.
1559 * Makefile.in (DISTFILES): Distribute ansi2knr.1
1561 * Makefile.in (stamp-h.in): Avoid running ./config.status if
1562 stamp-h does not exist yet. This avoids running it a second time
1563 just after the initial ./configure.
1564 Reported by David MacKenzie and Tom McConnell.
1566 * m4.h: Replace the enum debug_info declaration with a series of
1567 #define's. The Ultrix 3.1 compiler would otherwise need casting
1568 (int) to most references, when used in expressions.
1569 Reported by Tom McConnell.
1571 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
1573 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
1574 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
1575 calls the compiler. Previously, FP_PROTOTYPES was only calling
1576 the preprocessor; by not being subject to CFLAGS, this was
1577 discouraging those flags asking for ANSI compilation.
1578 * acconfig.h: Document HAVE_PROTOTYPES.
1579 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
1580 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
1581 Reported by Eric Backus.
1583 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
1584 from the environment. Default CFLAGS to -g if not set.
1585 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
1586 * lib/Makefile.in: Have CFLAGS substituted from configure.
1587 Reported by Eric Backus and Tom McConnell.
1589 * configure.in: m4_undefine changeword before using AC_ENABLE.
1591 * m4.h: Declare prototypes for error (for ANSI compilers only),
1592 prefix_all_builtins and reference_error.
1593 Reported by Tom McConnell.
1595 * input.c (set_word_regexp): Do not try to initialize the array
1596 test from a string, this does not work with non-ANSI compilers.
1597 Reported by Eric Backus.
1599 * Makefile.in (dist): Clean examples/ before saving it.
1600 (distclean-local): Also remove stamp-h.
1601 Reported by Eric Backus.
1603 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
1604 non ANSI compilers.
1605 Reported by Tom McConnell.
1607 * checks/Makefile.in (clean): Depends on mostlyclean.
1608 (mostlyclean): New goal.
1610 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
1612 * Makefile.in (DISTFILES): Distribute install.sh.
1613 * install.sh: New file, copied from elsewhere.
1614 Reported by Assar Westerlund and Kaveh R. Ghazi.
1616 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
1618 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
1619 * acconfig.h: Explain ENABLE_CHANGEWORD.
1621 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
1622 from code provided by Pete Chown]
1623 * m4.h: Add original_text field to u_t variant of union u.
1624 Declare TOKEN_DATA_FUNC macro.
1625 * builtin.c: Declare changeword.
1626 (m4_changeword): New function.
1627 * input.c: Include "regex.h", define variables with word regexps.
1628 (input_init): Initialize the word regexp.
1629 (set_word_regexp): New.
1630 (next_token): Declare local variables, use the previous code if
1631 default_word_regexp is true. Else, match using a new code. Save
1632 the original text.
1633 * macro.c (expand_token): Ship out original text if not a macro
1634 name.
1635 Reported by Krste Asanovic and Pete Chown.
1637 [These modifs all depend upon ENABLE_CHANGEWORD]
1638 * m4.h: Declare external user_word_regexp.
1639 * m4.c: Declare user_word_regexp, and initialize it from
1640 --word-regexp or -W, or NULL if not specified.
1641 * input.c: Use user_word_regexp if specified, instead of
1642 DEFAULT_WORD_REGEXP.
1644 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
1645 agree with it.
1647 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
1648 * checks/Makefile.in: Empty the suffix list.
1649 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
1651 * m4.c: Declare nesting_limit and initialize it to 250.
1652 Implement -LNUMBER or --nesting-limit=NUMBER to change its
1653 value.
1654 * m4.h: Declare nesting_limit as external.
1655 * macro.c (expand_macro): Stop execution whenever nesting limit
1656 is exceeded.
1657 Reported by Bengt Mertensson.
1659 * eval.c (evaluate): Diagnose excess characters in eval input.
1660 Things like `eval(08)' used to return 0 with no diagnostic.
1662 * m4.h: Capitalize first letter of all macro arguments in
1663 definitions.
1665 * m4.c: Declare warning_status, initialize it to 0. Add new
1666 option -E, or --fatal-warnings, which sets warning_status to
1667 EXIT_FAILURE instead.
1668 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
1669 EXIT_FAILURE if not otherwise done by header files.
1670 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
1671 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
1672 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
1673 argument of all M4ERROR calls.
1674 Reported by Noah Friedman.

1677 * examples/include.m4: Include incl-test.m4 instead of
1678 incl_test.m4.
1679 * examples/multiquotes.m4: Renamed from multi-quotes.m.
1681 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
1683 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
1684 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
1685 also tested it on a Sun Sparc workstation running SunOS 4.x.
1687 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
1688 49.format check, abusing a `union values' argument with sprintf
1689 without selecting the proper field. Now, save the formatting type
1690 first, delaying the fetch of the corresponding argument.
1691 Reported by Joseph E. Sacco and Tom Quinn.
1693 * format.c (format): Remove const from char *fmt declaration when
1694 not HAVE_EFGCVT, because a NUL may be forced into it.
1696 * m4.h: Declare atof() when not STDC_HEADERS.
1697 Reported by Joseph E. Sacco.
1699 * Regenerate configure using Autoconf 1.11, this corrects a
1700 problem about an incorrect cpp seting on NeXT 3.1.
1701 Reported by Alexander Lehmann.
1703 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
1705 * m4.h (_): Change argument from `x' to `Args'.
1707 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
1709 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
1710 bringing more evil than good on a few systems.
1711 Reported by Greg A. Woods.
1713 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
1715 * m4.h: Rename Args() to _().

1720 * stackovf.c: New file implementing stack-overflow detection.
1721 * configure.in: Check for getrlimit, sigaction. If all of
1722 standard headers, getrlimit and sigaction, define USE_STACKOVF and
1723 substitute ${U}stackovf.o for STACKOVF.
1724 * acconfig.h: Declare USE_STACKOVF.
1725 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
1726 * m4.h: Declare setup_stackovf_trap().
1727 * m4.c: Call setup_stackovf_trap().
1728 * tests/stackovf_test.sh: New file.
1730 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
1732 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
1734 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
1736 Sun Jan 30 14:24:19 1994 (pinard at icule)
1738 * m4.h: Remove definition of volatile, not used anymore.
1739 Reported by Jim Meyering and Joseph E. Sacco.
1741 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
1742 of `if ... else /* nothing */' for if macros.
1743 Reported by Jim Meyering.
1745 * builtin.c (m4_regexp): Reorganize the code for avoiding a
1746 warning from gcc about `repl' possibly used before defined.
1747 Reported by Jim Meyering.
1749 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
1750 Reported by Jim Meyering.
1752 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
1754 * m4.h: Move the conditional definition of volatile after the
1755 inclusion of system files, because they may define it first.
1757 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
1759 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
1760 get around a problem with Alpha make seeing a syntax error, there.
1761 Reported by Vern Paxson.
1763 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
1765 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
1766 Reported by Richard Stallman.
1768 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)

1771 instead of AC_HAVE_FUNCS.
1772 Reported by Noah Friedman.
1774 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
1776 * m4.c: Initialize show_help and show_version to zero.
1778 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
1779 Use them in exit() and usage() calls.
1781 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
1783 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
1784 syserr() macro. Delete errref, add reference_error and M4ERROR.
1785 * m4.c: Replace errref, which was returning an input reference
1786 string, with reference_error, which prints it on standard error.
1787 * builtin.c, output.c: Use errno as second parameter to error,
1788 instead of using syserr() with %s.
1789 * *.c: Use M4ERROR instead of error: no more errref() with %s.
1790 Doing so, the program name appears after the input reference
1791 instead of before, which eases M-x next-error processing.
1793 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
1795 * checks/get-them: Escape braces with backslashes in patterns,
1796 because HPUX-9.01 awk needs this.

1805 Declare xrealloc, for use in errref().
1806 * m4.c: Delete error_message_prefix() function, add errref().
1807 * *.c: Use error() systematically in place of all error macros,
1808 now that error() flushes stdout first. Make needed adjustments.
1810 * m4.h: Remove const in sys_errlist[] declaration, it creates
1811 conflicts on SGI and Alpha.
1812 Reported by Kaveh R. Ghazi.
1814 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
1816 * m4.c: Include <getopt.h> instead of "getopt.h".

1820 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
1821 use them wherever appropriate. Also use -I. for compilations.
1822 * lib/Makefile.in: Use -I.. for compilations.

1825 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
1826 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
1828 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
1830 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
1832 * input.c (input_init): Initialize quote and comment strings
1833 explicitely instead of calling set_quotes and set_comment: by
1834 doing so, we ensure we do not free uninitialized variables.
1836 * checks/check-them: Reverse arguments to both diff, so the
1837 expected is on the left and the obtained on the right.
1839 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
1840 macros. Delete declarations for m4error, warning, fatal and
1841 internal_error, add declaration for error_message_prefix.
1842 * m4.c: Delete m4error, warning, fatal and internal_error
1843 routines, add error_message_prefix routine.
1844 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
1845 warning with WARNING*, fatal with FATAL* and internal_error with
1846 INTERNAL_ERROR*.
1847 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
1848 this is not needed anymore.
1850 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
1851 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
1852 and debug_message, add declaration for debug_message_prefix.
1853 * debug.c: Remove static specifier for FILE *debug declaration.
1854 Delete debug_print and debug_message routines, add
1855 debug_message_prefix routine.
1856 * builtin.c, debug.c: Replace debug_print routine calls with
1857 DEBUG_PRINT* macro calls.

1862 * debug.c: Include <stdarg.h> or <varargs.h>.
1863 (trace_format): Use stdarg instead of varargs if __STDC__.
1865 * configure.in: Remove checks for vfprintf and _doprnt. These
1866 implementations use varargs tricks which are not portable enough.
1867 * lib/vfprintf.c: Deleted.
1868 * lib/_doprnt.c: Deleted.
1869 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
1870 Reported by Joel Sherrill.

1888 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
1889 Reported by Joel Sherrill.
1891 * builtin.c (prefix_all_builtins): Instead of the table size, use
1892 the null entry at end for stopping the loop. It was overwritten.
1893 Reported by Andreas Schwab and Jim Meyering.
1895 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
1896 Reported by Kaveh R. Ghazi.

1932 Reported by Tom McConnell.
1934 * Makefile.in (Makefile): Use $(SHELL).
1935 (config.status): Use $(SHELL). Use "config.status --recheck"
1936 instead of "configure --no-create", which is obsolete.
1937 Reported by Tom McConnell.
1939 Fri Nov 5 09:49:30 1993 Francois Pinard (pinard@compy.IRO.UMontreal.CA)
1941 * m4.c (usage): Use "%s" instead of "m4" in format string.

2147 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
2149 * Release 1.0.3
2150 This is still a beta release for the future GNU m4 version 1.1.
2152 * lib/alloca.c: New, from elsewhere.
2153 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2155 * m4.h: Do not define index/rindex if already defined. If
2156 FALSE/TRUE are already defined, do not redefine them, but merely
2157 define boolean typedef to int.
2159 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2160 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2161 because some C compilers do not like connectives with #ifdef.
2162 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2163 __GNUC__ and once for __STDC__.
2164 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2166 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2167 Makefile dependencies. Without it, make keeps destroying and
2168 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2170 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2171 to diversion/DIVERSION, this was a spelling error.
2173 * m4.c: Declare version[], remove #include "version.h".
2174 * version.h: Deleted.
2175 * Makefile.in: Remove references to version.h.
2177 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2178 production, by using a simpler and more robust algorithm. This
2179 solves the problem of synclines sometimes written in the middle of
2180 an output line. Delete sync_line() and output_lines variable.
2181 * m4.h: Remove sync_line prototype and output_lines declaration.
2182 * input.c (next_char), output.c (shipout_text): Remove references
2183 to output_lines.
2184 * input.c (push_file, pop_file): Merely put the value -1 in
2185 output_current_line instead of calling sync_line, for delaying a
2186 single `#line NUM FILE' before next output line. Do not test
2187 for sync_output, because this is unnecessary clutter.
2188 * output.c (make_divertion, insert_divertion): Idem.
2189 * input.c: Rename must_advance_line to start_of_input_line, for
2190 consistency.
2192 * debug.c (trace_header): Select a new debug line format, which
2193 better complies with GNU standards for formatting error messages.
2194 With option `-dfl', M-x next-error might be used on the output.
2195 * m4.c (vmesg): Adjust format of error output to GNU standards.
2196 * m4.texinfo: Adjust examples for `make check' to work.
2198 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2199 case for enum debug_info constants, which were all lower case.
2201 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2202 re_search_2.
2203 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2204 collected patches. I tried a few times using newer regex.[ch], it
2205 mysteriously stopped aborting with this one. Insecure feeling...
2206 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2208 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2210 * m4.c: Change `--no-warnings' to `--silent'.
2211 Reported by David MacKenzie.
2213 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2214 leave it off for now. See comment in m4.c for justification.
2215 Reported by David MacKenzie.
2217 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2218 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2220 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2222 * Makefile.in: Ensure recursive cleaning is done before local
2223 cleaning for all clean goals.
2225 * builtin.c (ntoa): Ensure the value is always interpreted as a
2226 signed quantity, whatever the radix is.
2228 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2230 * builtin.c, format.c, input.c: Split long lines.
2231 * m4.c: Use typedef macro_definition instead of struct
2232 macro_definition.
2233 * symtab.c: Use typedef symbol instead of struct symbol.
2235 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2237 * *.[ch]: Remove all trailing whitespace, in code and comments.
2239 * configure.in: Find some awk.
2240 * Makefile.in: Add $(AWK) to MDEFINES.
2241 * checks/Makefile.in: Transmit $(AWK) to get_them.
2242 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2243 awk script when switching files, because without this, mawk runs
2244 out of file descriptors.
2246 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2248 * Makefile.in (realclean): Delete m4.info*.
2249 Reported by Jim Meyering.
2251 * Makefile.in: Adjust and link with checks/Makefile.
2252 * checks/Makefile.in: New.
2253 * configure.in: Output checks/Makefile.
2255 * checks/get_them: Have the dnl header of each test more
2256 recognizable by next-error, also use a better message.
2258 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2260 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2261 And use that only if __GNUC__ since we're using it's GCC-specific
2262 semantics that tell the compiler the associated function doesn't
2263 return.
2265 * builtin.c (substitute): Don't use character as an array index.
2266 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2267 warnings with gcc -W -Wall on systems with qsort prototype.
2268 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2269 from gcc -W -Wall.
2271 * eval.c (most functions): Add parentheses to assignments used
2272 as truth values go avoid warnings from gcc -Wall.
2274 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2275 any functions that don't need external scope.
2277 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2278 (many functions and arrays): Declare `const'.
2280 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2282 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2283 removing the declaration from m4.h. Also rename false to FALSE
2284 and true to TRUE.
2286 * lib/Makefile.in (Makefile): New goal.
2288 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2289 so heavily loaded. It gets more easily overridable, calling make.
2290 Reported by Jim Meyering.
2292 * Makefile.in (dist): Get .fname from the current directory name,
2293 instead of from version.h. I need updating many files manually,
2294 when the version changes, version.h is just one of them.
2296 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2298 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2299 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2300 Reported by Tom McConnell.
2302 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2304 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2305 39.cleardiv, which were describing missing or spurious newlines.
2306 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2307 do not depend on machine word size, `/bin/false' implementation,
2308 or `wc' output format. `make check' is more dependable, now.
2310 * checks/check_them: Summarize the failed tests by listing their
2311 name, at end. If none, issue `All checks successful'. Output
2312 `Checking' instead of `Input file:'.
2314 * checks/get_them, checks/check_them: Reindented.
2316 * Makefile.in (dist): chmod a+r before making the tar file.
2318 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2320 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2322 * input.c (next_token): Reinitialize token_buttom just after using
2323 it as a watermark with obstack_free. Or else, a future token, big
2324 enough for triggering reallocation of the obstack chunk, could
2325 void the initialized value of token_buttom, later causing panic in
2326 obstack_free. Rename token_buttom to token_bottom everywhere.
2328 * m4.h: Before declaring errno, first include <errno.h> and
2329 ensure that it does not define errno.
2330 Reported by Richard Stallman.
2332 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
2334 * builtin.c: Define and use DECLARE macro for builtins.
2336 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
2337 argument, this is a common idiom for introducing long comments.
2339 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
2340 arguments. The last argument was silently ignored.
2342 * m4.c (cmd_error): Add a missing semicolon before va_end().
2344 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
2346 * Makefile.in: Now handle protoized sources. Define and use U.
2347 Compile and use ansi2knr with old compilers. Update DISTFILES.
2348 Add `aclocal.m4' to `configure' dependencies.
2349 * ansi2knr.c: New, from Ghostscript distribution.
2350 * configure.in: Define U through FP_PROTOTYPES for old compilers.
2351 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
2352 * aclocal.m4: New, provide FP_PROTOTYPES.
2353 * m4.h: Conditionnaly protoized through Args, save for varags.
2354 * builtin.c: Protoized. Then:
2355 Include <sys/types.h> if size_t is not defined, before "regex.h".
2356 (m4_ifelse): Fetch built-in name properly for diagnostic.
2357 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
2358 (m4_regexp): Add const to `msg' declaration.
2359 (m4_patsubst): Add const to `msg' declaration.
2360 * debug.c: Protoized, save for varargs.
2361 * eval.c: Protoized.
2362 * format.c: Protoized.
2363 * input.c: Protoized.
2364 * m4.c: Protoized, save for varargs. Then:
2365 (xfree): Accept void * instead of char *.
2366 (xmalloc): Return void * instead of char *.
2367 (xrealloc): Accept and return void * instead of char *.
2368 * macro.c: Protoized.
2369 * output.c: Protoized.
2370 * path.c: Protoized. Then cast some (char *) over xmalloc's.
2371 * symtab.c: Protoized.
2373 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
2375 * m4.texinfo: Remove directory from diagnostics in 30.include,
2376 51.eval, 56.errprint and 57.m4exit tests.
2378 * m4.h: Remove declarations for int or void system functions, they
2379 cause more conflicting trouble than they make good.
2381 * configure.in: Avoid configuration header file. Add some tests.
2382 * m4.h: Remove #include "config.h".
2383 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
2384 Then, rewritten for better compliance with GNU standards.
2386 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
2388 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
2389 because of a misplaced #endif.
2391 * Many *.[hc] files: Correct intra-line spacing here and there,
2392 according to GNU indent 1.6 advice.
2394 * configure.in: New, using Autoconf 1.2.

2401 Reported by Jason Merrill.
2403 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
2404 etc/nextvers.sh. Release numbers will be edited `by hand'.
2405 * version.h: De-automatize, force value in.
2407 * m4.c: Changes in order to use a newer getopt.h.
2408 Reported by David MacKenzie.
2410 * checks/: New name for examples/.
2411 * checks/get_them: New location for etc/get_examples.
2412 * checks/check_them: New location for etc/check_examples.

2415 * Delete empty etc/.
2416 * examples/: New name for test/.
2418 Tue Mar 10 00:29:46 1992 Francois Pinard (pinard at icule)
2420 * Makefile.in (check): Add m4 as dependency.
2422 * m4.c: Accept --no-warnings instead of --no_warnings, and
2423 --no-gnu-extensions instead of --no_gnu_extensions. Make the
2424 usage message more informative.
2425 Reported by David MacKenzie.

2441 Reported by Richard Stallman.
2443 * config/hmake-unicos, config/s-unicos.h: New files.
2444 Reported by Hal Peterson.
2446 * eval.c (exp_term): Have N^0 return 1.
2447 Reported by Michael Fetterman.

2481 * The builtins incr and decr are now implemented without use of
2482 eval.
2484 * The builtin indir is added, to allow for indirect macro calls
2485 (allows use of "illegal" macro names).
2487 * The debugging and tracing facilities has been enhanced
2488 considerably. See the manual for details.
2490 * The -tMACRO option is added, marks MACRO for tracing as soon
2491 as it is defined.
2493 * Builtins are traced after renaming iff they were before.
2495 * Named files can now be undiverted.
2497 * The -Nnum option can be used to increase the number of
2498 divertions available.
