1061 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
1062 choice, since that's what we do with --enable-largefile etc.
1063 Redo indenting and assignments to simplify things a bit, and make
1064 the parens work with Emacs.
1066 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo
1067 in my previous change: AC_C_OPENMP -> AC_OPENMP. Reported by Bruno

1166 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
1167 for a.* when searching for executables, as this prevents users

1181 AC_CHECK_TYPE, AC_CHECK_TYPES.
1182 * doc/autoconf.texi (Generic types): C types must be type-names
1183 (the C terminology), not type-ids (the C++ term). C++ types
1184 must not be anonymous.
1185 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
1186 for C++; this drops support for anonymous struct and union types,
1187 which were problematic anyway.
1188 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
1189 for C++.
1191 2007-04-12 Jim Meyering <jim@meyering.net>

1204 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
1205 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
1206 with objects too. Document the restrictions on its use.
1207 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1208 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1209 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1210 works but the latter doesn't, then it's a valid type.
1211 This lets people use function types and so forth.
1212 For C++ there doesn't seem to be a simple solution, so leave it alone.
1213 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1214 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1215 AC_CHECK_TYPE; that wasn't documented or necessary.

1267 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
1268 nonstandard grep R.E. escape sequences.
1270 2007-03-17 Jim Meyering <jim@meyering.net>
1272 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
1273 (Limitations of Usual Tools): Also list \< and \>, and mention that
1274 HP-UX's grep, like the one from Solaris, does not support that syntax.
1276 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1278 * doc/autoconf.texi (Specifying Names): `--host' does not
1279 change the build type.

1294 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
1295 universal binaries. Problem reported by Elias Pipping.

1383 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1385 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1386 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1387 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1388 substitution will still be done by the special code.
1389 Report by Jim Meyering.
1391 * doc/autoconf.texi (File System Conventions): Mention that
1392 $PATH_SEPARATOR is for the build system only.

1412 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1413 early on the reader side, drop stderr of the input to avoid
1414 `broken pipe' error output; this may happen even with shell
1415 builtin `echo' of some bash versions. Reports by Ian Macdonald
1416 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1418 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1434 and change it a bit to make things clearer.
1435 (Optimization and Wraparound): Clarify whether the compiler
1436 will generate an infinite loop for the example derived from
1437 Autoconf's mktime test.
1438 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1439 Also, clarify unsigned multiplication overflow.
1441 2007-01-04 Eric Blake <ebb9@byu.net>

1455 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1456 feedback. The most important changes document what happens when
1457 you convert an out-of-range value to a signed integer type, and
1458 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1459 a + b.
1461 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1462 rewrite, taking notions from the recent discussion on the gcc and
1463 autoconf mailing lists; please see
1464 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1465 and follow the many links.
1466 (Integer Overflow Basics, Signed Overflow Examples):
1467 (Optimization and Wraparound, Signed Overflow Advice):
1468 (Signed Integer Division): New sections.
1470 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1472 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1473 preprocessor macro arguments in traced name.
1474 * doc/autoconf.texi (Defining symbols): Document longstanding
1475 support for AC_DEFINE-ing macros with arguments, and document
1476 behavior when the same variable has multiple AC_DEFINEs.
1477 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1478 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1479 macros directly, giving much shorter and simpler code.
1481 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1483 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1484 space before "$ac_configure_args" to prevent a 'config.status
1485 --recheck' failure if ac_configure_args doesn't contain a leading
1486 space. This works around a problem with the XEmacs configure.ac,
1487 which uses the (undocumented) ac_configure_args variable
1488 inconsistently with Autoconf.
1490 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1492 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1493 Include <limits.h>, and use its INT_MAX to rewrite the
1494 j loop so that it does not overflow 'int'. Problem reported by
1495 Ralf Wildenhues in
1496 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1497 Play it safe by shifting left by 1 rather than multiplying by 2,
1498 as GCC is less likely to optimize this away when the value
1499 is signed (when it assumes overflow leads to undefined behavior).
1500 Also, don't assume time_t uses two's complement.
1502 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1504 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1505 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1506 dumps core on it. Report by Tim Rice.
1508 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1510 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1511 --disable-option-checking to --help output even when
1512 AC_PRESERVE_HELP_ORDER is not used.
1513 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1514 --with argument, rather than argument with [-.] replaced by
1515 underscores.
1516 * NEWS: Fix typo in previous change; the news was in the
1517 wrong section.
1519 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1521 * NEWS: Warnings are now generated by default for unknown
1522 --enable-* and --with-* options.
1523 * doc/autoconf.texi (Option Checking): Renamed from
1524 (Configure Option Checking). Tighten up the wording a bit.
1525 (External Software, Package Options): Cross-reference to Option
1526 Checking, and use this to shorten our section.
1527 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1528 "$x" to test "x$foo" != x.
1529 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1530 Don't warn if $enable_option_checking is "no".
1531 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1532 ac_unrecognized_opts to the empty string.
1533 Don't echo the unrecognized opts, as this might mishandle
1534 backslashes or leading -.
1535 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1536 usage next to the other --disable-FEATURE options in the
1537 help string.
1539 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1541 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1542 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1543 Print warning for unrecognized --with and --enable options
1544 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1545 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1546 Disable option checking when subdirs are configured.
1547 (AC_OUTPUT): If warnings are enabled, print warning about
1548 unrecognized --with and --enable options at the end of
1549 the configure output (as well as at the beginning).
1550 * doc/autoconf.texi (Option Checking): New node.
1551 Document new option warning functionality.
1553 2006-12-16 Eric Blake <ebb9@byu.net>
1555 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1556 * NEWS: Start news for current version.
1558 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1560 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1561 Define HAVE_GETMNTENT to 1, not to the empty string.
1562 Problem originally reported by Jochen Friedrich in
1563 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1565 This change prompted by a problem report by Andrey Simonenko in
1566 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1567 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1568 object-like macros only, in the traditional portable character
1569 set.
1570 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1571 Warn about attempts to define things that are not identifiers.
1572 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1573 awful hack that AC_DEFINEd macro names containing parentheses.
1575 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1577 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1578 too drastic, even if Texinfo in theory requires it for info mode.
1580 (config.status Invocation): Renamed back from Recreating a
1581 Configuration).
1582 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1583 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1585 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1587 * NEWS: Version 2.61a.
1589 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1590 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1592 * NEWS: Document changes with echo and printf, and the lack
1593 of limits on the total size of multi-line values of substituted
1594 variables, and the AC_FUNC_FSEEKO fix.
1596 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1598 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1599 Writing configure.ac.
1600 (Autoconf Input Layout): Renamed from configure.ac Layout.
1601 (Recreating a Configuration): Renamed from config.status Invocation.
1602 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1603 (acconfig Header): Renamed from acconfig.h.
1604 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1605 (Writing Testsuites): Renamed from Writing testsuite.at.
1606 (Autom4te Cache): Renamed from autom4te.cache.
1608 * BUGS: Remove mention of VPATH problem, since it's now documented
1609 not to be a bug in the Autoconf build procedure itself, but rather
1610 a problem with the proprietary `make' programs.
1612 * doc/autoconf.texi (Build Directories): Add a cross reference
1613 to VPATH and Make.
1615 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1616 * doc/standards.texi: Sync from gnulib.
1618 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1619 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1620 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1621 generated automatically.
1623 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1625 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1626 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1627 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1629 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1631 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1632 `CEOF$ac_eof' special marker, the awk script cannot contain a
1633 line matching `^CEOF', so this is not needed any more.
1634 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1635 special marker in the test.
1637 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1639 * tests/tools.at (autom4te preselections): Use `find -newer';
1640 remove one of the sleeps.
1642 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1643 more readable, using ...
1644 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1646 * doc/autoconf.texi (autoheader Invocation): Do not double-
1647 quote the parameter of `AH_BOTTOM' in the example.
1649 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1651 * doc/autoconf.texi (Configuration Headers): Remove the
1652 example with multiple input files.
1653 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1654 multiple input files.
1656 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1658 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1659 creating the awk substitution script, handle one input line at a
1660 time, so that the maximum length of a substituted (multi-line)
1661 value is not limited by the size of the sed pattern space.
1662 The trade-off is a slightly repetitive sed script.
1663 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1664 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1665 * tests/torture.at (Substitute a 2000-byte string): Increase the
1666 test with several long lines, they should not be caught by sed
1667 limits any more.
1669 * tests/tools.at (autom4te preselections): New test, to flag
1670 entries missing from autom4te.cfg.
1671 Report by David Byron <dbyron@hheld.com>.
1673 * tests/torture.at (Substitute a 2000-byte string): Actually use
1674 AC_PROG_AWK, so the last change works as intended.
1675 (Substitute and define special characters): Likewise.
1676 (Substitute a newline): Likewise.
1678 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1679 instead of `awk' consistently.
1680 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1681 * tests/torture.at (Torturing config.status): Test both the
1682 result of AC_PROG_AWK and plain awk.
1683 (Substitute a 2000-byte string): Likewise.
1684 (Substitute and define special characters): Likewise.
1685 (Substitute a newline): Likewise.
1687 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1689 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1690 can be assigned to a function pointer. Problem reported by
1691 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1692 part of a patch by Ralf Wildenhues in that same bug report.
1694 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1696 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1697 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1699 2006-12-01 Eric Blake <ebb9@byu.net>
1701 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1702 cross-compiling from cygwin to mingw.
1703 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1704 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1705 to lib/autoconf/c.m4.
1707 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1709 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1710 string for more reliable failure. Wrap the entire test that
1711 causes the broken Solaris printf to dump core, in a subshell,
1712 so the segmentation fault message is reliably suppressed.
1713 Fix shell expansion errors by using /usr/ucb/echo always;
1714 avoid an error on systems without it by another subshell.
1715 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1716 subshell-$as_echo to `as_echo', for better error message.
1718 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1720 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1721 `BASH_SOURCE' contain a newline, set them to empty, as they may
1722 not be unset.
1724 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1726 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1727 years and is too hard to maintain now. The last straw was
1728 reported by Jerker Baeck in
1729 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1730 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1731 * doc/autoconf.texi (Particular Functions): Move
1732 AC_FUNC_SETVBUF_REVERSED from here...
1733 (Obsolete Macros): ... to here. Say that it does nothing now.
1734 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1735 Turn into (almost) a no-op.
1737 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1738 (AC_C_VOLATILE):
1739 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1740 These macros are obsolescent and new applications shouldn't need them.
1741 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1742 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1743 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1744 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1745 (AC_FUNC_VPRINTF): Likewise.
1746 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1747 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1748 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1750 * doc/autoconf.texi (Setting Output Variables): Mention that
1751 @VAR1@VAR2 has unspecified behavior. Problem reported by
1752 Ralf Wildenhues.
1753 * NEWS: Mention this.
1755 * Makefile.am: Put only a single '#' into the copyright notice,
1756 so that it's also present in the output file. Standardize wording
1757 in makefile copyright notices to match GNU coding standards.
1758 * bin/Makefile.am: Likewise.
1759 * doc/Makefile.am: Likewise.
1760 * lib/Makefile.am: Likewise.
1761 * lib/freeze.mk: Likewise.
1762 * lib/autoconf/Makefile.am: Likewise.
1763 * lib/autoscan/Makefile.am: Likewise.
1764 * lib/autotest/Makefile.am: Likewise.
1765 * lib/m4sugar/Makefile.am: Likewise.
1766 * man/Makefile.am: Likewise.
1767 * tests/Makefile.am: Likewise.
1768 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1769 one-line file.
1771 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1773 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1774 in the sed script that mangles the awk script: delete up to the
1775 first exclamation mark only.
1776 * tests/torture.at (Substitute and define special characters):
1777 Test '!' too.
1779 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1781 Rewrite config files generation: avoid quadratic growth in
1782 the number of substituted variables by using awk instead of sed
1783 for the bulk of the substitutions.
1784 * NEWS: Mention this.
1785 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1786 forbidden in the output (and thus input) file.
1787 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1788 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1789 generate just one large awk script for substitutions,
1790 eliminating much of the earlier complexity, while adding some
1791 new complexity. Only expand the substitution templates at
1792 configure time, for smaller configure script size. If
1793 _AC_SUBST_FILES are used, test 'awk' for working getline support
1794 at config.status time. If absent, interpolate through the
1795 shell. The awk script was written with much help
1796 from Paolo Bonzini and Paul Eggert.
1797 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1798 (_AC_SED_FRAG_NUM): Likewise.
1799 (_AC_SUBST_CMDS): Renamed from...
1800 (_AC_SED_CMDS): ...this.
1801 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1802 * tests/torture.at (Substitute a 2000-byte string): Also
1803 substitute a line with 1000 words, and a variable with several
1804 long lines.
1805 (Substitute and define special characters): Test awk special
1806 characters, and put substitution input strings `@foo@' in the
1807 output, to test that no recursion happens; test several other
1808 combinations from Paolo Bonzini.
1810 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1812 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1813 that replaced echo with AS_ECHO where this wasn't necessary.
1814 Problem reportd by Ralf Wildenhues.
1815 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1816 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1817 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1819 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1821 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1823 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1825 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1826 that traditional Awk lacks 3-arg "split". It has it.
1827 Mention that FS must be a single character, and a few other
1828 99-byte limits of traditional Awk.
1829 Mention that if (i in a) doesn't work with traditional Awk.
1831 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1833 * tests/autotest.at (BSx641-newline in command):
1834 (BS-BS-newline in command, BSx640-newline in command):
1835 (Newline-CODE-BS-newline in command):
1836 (Single-quote-BS-newline in command):
1837 (Single-quote-newline-BS-newline in command):
1838 Use printf '%s\n' instead of echo, for portability to hosts
1839 where echo interprets backslashes. This will break on hosts
1840 that lack printf, but for now let's assume all such hosts
1841 are dead (if not, we should get reports of test failures).
1843 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1845 'echo' has some portability problems, when given a first argument
1846 with a leading '-', or when given any argument containing '\'.
1847 Avoid using 'echo' in these cases.
1848 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
1849 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
1850 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1851 * lib/autotest/general.m4 (AT_INIT): Likewise.
1852 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
1853 argument might be unportable.
1854 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
1855 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
1856 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
1857 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
1858 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
1859 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
1860 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
1861 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
1862 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

1871 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
1872 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1873 * bin/autoconf.as: Redo verbose flag implementation, as the old
1874 scheme wouldn't work with AS_ECHO.
1875 * lib/autotest/general.m4 (AT_INIT): Likewise.
1876 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1877 Don't use ECHO_T, since ECHO_N is now reliable.
1878 * lib/autotest/general.m4 (AT_INIT): Likewise.
1879 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1880 rather than using a here-document to put the script into a file.
1881 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1882 use AS_ECHO.
1883 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1884 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1885 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
1886 bug, but we might as well stop using ECHO_N and ECHO_C internally.
1887 * lib/autotest/general.m4 (AT_SETUP): Likewise.
1888 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
1889 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1890 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
1891 operand, as AS_ECHO requires. Avoid double file name expansion.
1892 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1893 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

1895 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1896 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1897 Double-quote strings that would otherwise contain M4 comments.
1898 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1900 * configure.ac (AC_INIT): Bump to 2.61a.
1901 * NEWS: Likewise.
1903 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>

1907 * configure.ac (AC_INIT): Bump to 2.61.
1908 * NEWS: Likewise.
1910 * tests/autotest.at (Macro with backslash in a test title):
1911 Comment out for now, as this tests neither fails nor passes
1912 reliably. Problem reported by Ralf Wildenhues.
1914 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1916 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
1917 in previous change, which caused test failures.
1919 2006-11-16 Stepan Kasal <kasal@ucw.cz>
1921 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
1922 code for --enable, --disable, --with, and --without to...
1923 (_AC_INIT_PARSE_ENABLE): ... a new macro.
1924 * doc/autoconf.texi (Package Options):
1925 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
1927 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

1960 on a char value; thanks to Paul Eggert for the code.
1961 Both of these suggestions from Eugene Y. Vasserman.
1964 Import these changes from texinfo via gnulib:
1966 2006-11-08 Karl Berry <karl@gnu.org>
1968 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
1969 as well as pdf images, since they are supported in pdftex with
1970 no further ado.
1972 2006-11-05 Karl Berry <karl@gnu.org>
1974 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

1988 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
1990 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
1991 benefit of platforms like Solaris+GCC where it is common to have a
1992 non-working g++ installation.
1994 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1995 and Joel E. Denny <jdenny@ces.clemson.edu>
1996 and Paul Eggert <eggert@cs.ucla.edu>

2004 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2005 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2006 Imported from a similar patch to gnulib by Bruno Haible.
2008 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2010 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
2011 * doc/autoconf.texi (C Compiler): Document them.
2012 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
2013 New macros, taken from gnulib.
2015 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

2024 Automake 1.10 nor future Automake 11.1 (sic).
2026 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
2027 and Stepan Kasal <kasal@ucw.cz>
2029 Handle special characters in test case titles correctly.

2034 argument. Extend to check titles printed by ./micro-suite and
2035 ./micro-suite -l and the title in micro-suite.log.
2036 (Backquote in a test title,
2037 Single-quote in a test title,
2038 Double-quote in a test title): Don't expect failure anymore.
2039 (Backslash in a test title): Put a non-whitespace character after the
2040 backslash so that Bourne shells might actually see it as an escape
2041 sequence.
2042 (Brackets in a test title,
2043 Pound in a test title,
2044 Comma in a test title,
2045 Quoted Macro in a test title,
2046 Macro in a test title,

2049 Macro with double-quote in a test title,
2050 Macro with backslash in a test title): New tests expected to fail.
2051 * tests/torture.at (#define header templates): M4-quote this title in
2052 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2053 The visible effect was a stray [] in the testsuite output.
2055 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2057 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2058 `trap ... 0' inside a function, for AIX sh.
2060 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2062 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2063 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2064 5363) simply issues a warning when dividing by zero at compile
2065 time. Problem reported by Elias Pipping.
2067 2006-10-26 Eric Blake <ebb9@byu.net>
2069 * THANKS: Update.
2070 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2071 show effect on macros that expand with commas.
2072 Reported by Joel E. Denny.
2074 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
2075 Also work with M4 1.4.8.

2089 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

2096 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2098 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2099 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2100 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2101 reported by Nelson H. F. Beebe for Coreutils 6.4.
2103 * tests/tools.at (autoconf --trace: user macros): Remove test
2104 for tracing multiline macros, since m4 1.4.7a uses a different
2105 way to number lines. Problem reported by Ralf Wildenhues.
2107 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2109 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2110 /dev/null since the heuristics for interactive behaviour was
2111 fixed in CVS m4.
2113 * bin/autom4te.in: With --force, always refresh the output
2114 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
2116 * bin/autoconf.as: Fix the verbose message at the end.
2118 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

2134 AC_CACHE_CHECK_INT, since it's no longer public.
2135 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
2136 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
2138 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2140 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
2142 2006-10-19 Eric Blake <ebb9@byu.net>
2144 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.

2146 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
2147 m4_mkstemp.
2148 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

2156 Standards.

2164 2006-10-14 Stepan Kasal <kasal@ucw.cz>
2166 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
2167 looking for special shell characters.
2168 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
2169 macro defined by AS_VAR_PUSHDEF before passing it as a
2170 parameter.
2171 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
2172 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

2181 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2183 (Imported from Automake.)
2184 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2185 which incorrectly sets the mode of an existing destination
2186 directory. In some cases the unpatched install-sh could do the
2187 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2188 system. We hope this is rare in practice, but it's clearly worth
2189 fixing. Problem reported by Alex Unleashed in
2190 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2191 Also, don't bother to check for -m bugs unless we're using -m;
2192 suggested by Stepan Kasal.
2194 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2196 Import this change from Automake:
2198 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
2199 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
2200 is enabled by default with gnu and gnits strictness.
2201 Report from Bruno Haible.
2203 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
2204 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
2205 gnu and gnits modes.
2207 Import this change from Config:
2209 2006-09-20 Ben Elliston <bje@gnu.org>
2210 * build-aux/config.sub (score, score-*): New.
2212 Import this change from Gnulib:
2214 2006-09-16 Karl Berry <karl@gnu.org>
2215 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
2216 to avoid sectioning errors.
2218 Import these changes from Texinfo:
2220 2006-10-04 Karl Berry <karl@gnu.org>
2221 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
2222 (\quoteexpand): rename to \rquoteexpand.
2223 (\codequoteleft): new def, to look for @set codequotebacktick.
2224 (\lquoteexpand, \quoteexpand): new defs.
2225 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
2226 (\code): must use new \...Char values, since now ` is active.
2228 2006-08-26 Karl Berry <karl@gnu.org>
2229 * build-aux/texinfo.tex (\textdegree): New command.
2231 2006-08-12 Karl Berry <karl@gnu.org>
2232 * build-aux/texinfo.tex (error \box0): smaller font.
2234 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2236 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
2238 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2240 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2241 added to the template can get mangled.
2243 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2245 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2246 include the default headers, and redefine obstack_chunk_alloc
2247 and obstack_chunk_free. Fixes false failure with glibc.
2249 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2251 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
2252 for backward compatibility with Libtool 1.5.22. Problem reported
2253 by Ralf Wildenhues.
2255 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2257 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
2258 AC_PROG_CC.
2259 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
2261 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2263 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
2264 the NonStop platform.
2265 * doc/autoconf.texi (Posix Variants): Likewise.
2266 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
2268 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2269 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2270 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2271 Use a better substitute, by inspecting the output of "ls"
2272 rather than just using ":".
2273 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2274 rather than AS_EXECUTABLE_P, since we needn't worry about
2275 non-regular files here.
2277 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2278 due to configuration hassles with this. See Tonya Underwood's report
2279 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
2280 * doc/autoconf.texi (Special Shell Variables): Likewise.
2282 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2283 Stepan Kasal <kasal@ucw.cz>
2285 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
2286 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
2288 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2290 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2291 initialization which is not inherited through the environment
2292 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2293 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2295 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2297 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2298 problems with mkdir -p -m.
2300 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2302 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2303 comment about ac_cpp_err; it was incorrect, and anyway
2304 ac_cpp_err is being removed below.
2305 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2306 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2307 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2308 nobody uses it.
2309 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2310 with werror_flag and conftest.err and so forth. This is more
2311 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2312 and anyway the user shouldn't normally want to see this gorp logged.
2313 Problem reported by Ralf Wildenhues.
2314 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2315 empty, not 'no', since the rest of the code uses 'test -z'.
2317 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2319 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2320 Use a single call to AC_DO_TOKENS rather than multiple, for
2321 efficiency.
2322 (_AC_LINK_IFELSE): Test that resulting file is executable.
2323 Problem reported by mwoehlke in
2324 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2326 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2327 than creating a file to use with test -x; this is much faster.
2329 2006-10-02 Bruno Haible <bruno@clisp.org>
2331 * lib/autom4te.in (Automake-preselections): Add
2332 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2334 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2336 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2337 standard error, `experr' should be used, not `expout'.
2339 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2341 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2342 fseeko testing program twice; just use the earlier result.
2343 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2344 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2345 still doesn't let the program compile.
2346 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2347 failed.
2349 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2350 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2351 include it, without including anything else.
2352 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant

2482 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2483 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2484 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2485 assume C89.

2583 deal with LEXLIB.
2584 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2585 didn't work if some values were cached but not others. Test for
2586 broken lex libraries like native ia64-hp-hpux11.22; see
2587 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2588 work around the problem by preferring an empty LEXLIB to -lfl or
2589 -ll. Let the user set LEXLIB='' to indicate no library needed.

2790 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2791 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2793 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2795 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2796 after -R regardless of host. Patrick Welche reports that this
2797 fixes things on NetBSD 3.99.
2799 * NEWS: Recommend M4 1.4.5.
2800 * README: Likewise.
2801 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
2802 * tests/tools.at (autom4te cache): Update wording of diagnostic
2803 to match M4 1.4.5.
2805 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2807 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2808 under AC_C_VOLATILE.
2809 (Volatile Objects): Be a little less skeptical about what
2810 "volatile" means. Derived from thoughts by Ben Pfaff in
2811 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2813 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2815 * doc/autoconf.texi: Fix some typos.
2817 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2819 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2820 more globally, since the 2006-06-30 patch didn't suffice. Problem
2821 reported by Keith Marshall. Also, don't bother with builddir2,
2822 since it shouldn't be needed any more.
2824 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2826 * doc/autoconf.texi (Generic compiler characteristics):
2827 Document AC_COMPUTE_INT. Fix wrong statements on Default
2828 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
2830 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
2831 (_AC_COMPUTE_INT): Add obsoletion warnings.
2832 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
2833 AC_COMPUTE_INT.
2835 * NEWS: Document change.
2837 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
2839 * doc/autoconf.texi (Volatile Objects): New section.
2841 * NEWS: Document previous change.
2843 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2845 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2846 Require that long long int be at least 64 bits wide. C99 requires
2847 this and enough programs depend on it so we should check for it.
2848 Bruno Haible reports in
2849 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2850 that long long int is 32 bits wide with some nonstandard compilers.
2851 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2853 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2855 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2856 to a nonexistent file, so that we don't have to worry about
2857 a local site configuration that doesn't use /usr/local.
2858 Problem reported by Keith Marshall in
2859 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2861 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2863 * doc/autoconf.texi: Be more consistent about using @acronym with
2864 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2865 quite right (it talked about "OSF/Tru64", even though the
2866 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2867 and it even mentioned "OSF 4"!) and at this point there's little
2868 reason to talk about OSF any more, since it died in 1994.
2869 (Specific Compiler Characteristics): Simplify example of
2870 negative-size array.
2871 (File Descriptors): Reorder to make the text flow better.
2872 Remove joke about "appreciate the various levels"; I didn't get it.
2873 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2874 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2875 (File Descriptors, Limitations of Usual Tools):
2876 Tone down the advice against renaming or removing open files.
2877 (Limitations of Usual Tools): Add a new section, on 'rm'.
2879 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2881 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2882 -lXt in LIBS, idea from Karsten Hopp; this was due since
2883 this change:
2885 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2886 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2887 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2888 (which belong to Xt, not X itself). See Debian bug 327655.
2890 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2892 * configure.ac (AC_INIT): Bump to 2.60a.
2893 * NEWS: Update.
2895 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2897 Version 2.60.
2899 * configure.ac, NEWS: Update.
2901 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2903 * config/texinfo.tex: Sync from upstream.
2905 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2906 quadrigraph correctly in traces.
2908 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2909 Fix typos.
2911 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2912 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2913 not defined.
2914 * doc/autoconf.texi (Changed Directory Variables): New node,
2915 to document the whole `datarootdir' business a bit better.
2916 * NEWS: Update.
2917 * tests/torture.at (datarootdir workaround): Extend test.
2918 Prompted by report by Alexandre Julliard.
2920 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2922 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2923 when using default mode of IBM C 6 for AIX. Problem and two-line
2924 fix reported by Larry Jones.
2926 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2928 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2929 about literal '${datarootdir}' if a definition is found in the
2930 output file.
2932 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2934 * NEWS: Use "M4" rather than "m4" when appropriate.
2935 Problem reported by Eric Blake.
2936 * doc/autoconf.texi: Likewise.
2937 Use @acronym around BSD, GCC, and GNU when appropriate.
2938 (Why GNU M4): Renamed from "Why GNU m4".
2939 (Redefined M4 Macros): Mention that Posix
2940 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2941 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2942 to int.
2944 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2946 * bin/autom4te.in (handle_output): Do not forbid the empty
2947 pattern.
2948 * tests/tools.at (autoconf: the empty token): New test.
2950 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2952 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2953 calls, so that we do not care whether they are LIFO or FIFO;
2954 in the m4_wrap, do not check which diversion is the topmost
2955 one, just check that the stack is balanced at the end.
2956 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2957 base diversion forever--pop the previous diversion before
2958 opening the new one; consequently, remove the m4_wrap call.
2959 * lib/autotest/general.m4 (AT_INIT): Likewise.
2960 * tests/m4sugar.at: Do not use
2961 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2963 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2964 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2966 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2967 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2968 Rework example of m4wrap token-pasting trouble so that it doesn't
2969 care whether it's LIFO or FIFO.
2970 Fix some "contrary to"s that are awkward in English.
2972 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2974 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2975 to `yes' instead of `int$1_t' if the type is found, for more
2976 consistent configure output (where $1 is the number of bits).
2977 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2978 Suggested by Bruno Haible.
2980 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2981 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2982 with system headers. Report by Bruno Haible.
2984 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2986 * config/config.guess, config/config.sub: Sync from upstream.
2988 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2989 in order to avoid picking up an older installed frozen m4sh.m4f.
2990 Besides an outdated shell startup, this could have been created
2991 by an earlier M4 version with incompatible frozen file format.
2993 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2995 * README: Recommend m4 1.4.4 instead of 1.4.3..
2996 * doc/autoconf.texi: Likewise.
2997 (Special Chars in Names): Say that $(.FOO) is portable, as
2998 suggested by Stepan Kasal.
2999 (Installation Directory Variables, Build Directories):
3000 (Automatic Remaking, Subdirectories, Fortran Compiler):
3001 (Making testsuite Scripts, Defining Directories):
3002 Quote variable usages better.
3003 (Making testsuite Scripts): Add clean-local rule to makefile
3004 snippet, by Eric Blake.
3005 (Installation Directory Variables): Fix table item font.
3006 Reword slightly to clarify. Generalize advice about
3007 not using special characters to include all file-related
3008 vars, not just VPATH.
3009 (Special Chars in Variables): Warn about special characters in
3010 $(srcdir) too.
3011 (Assignments): Clarify default-value example as suggested by
3012 Ralf Wildenhues in
3013 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3014 (Special Shell Variables): Note leading ./ or ../, as suggested
3015 by Eric Blake.
3016 (Limitations of Builtins): Under cd, warn about CDPATH.
3017 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3018 Ralf Wildenhues.
3020 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3022 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3023 `@var', for texi2html.
3024 (Systemology): Some more word wrapping, for DVI output.
3025 (autom4te Invocation): The short option for `--melt' is `-M',
3026 not `-m'.
3028 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3030 * doc/autoconf.texi: More formatting and English tweaks,
3031 many suggested by Ralf Wildenhues.
3032 Reword to avoid "@code{...}'s" and the like, since it's ugly
3033 with Emacs info mode. discontents -> woes.
3034 Put a few "will"s back. time stamp -> timestamp.
3035 side-effect -> side effect.
3037 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3039 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3040 Warn about $@ not persisting. Problem reported by Julien Danjou in
3041 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3042 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3043 Mention other special chars, too.
3045 2006-06-14 Eric Blake <ebb9@byu.net>
3047 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3049 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3051 * doc/autoconf.texi: Some systematic minor improvements, as
3052 follows. Use "makefile" when talking about makefiles
3053 generally (which might be named "makefile" or "Makefile" or even
3054 "foo.mk"), "Makefile" when talking about a specific makefile
3055 called "Makefile". This unclutters the text from weird quotes
3056 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3057 values" rather than "@var{foo}s" and similar constructs containing
3058 "}s". Use "Make rules" rather than "Makefile rules". Minor
3059 English-language improvements. Change the prefix "sub-" to "sub"
3060 and "re-" to "re".
3061 Put blank lines around examples more consistently.
3062 Avoid "rather" and "very" as intensifiers.
3063 Avoid "will" as an auxiliary.
3064 (Limitations of Make): Split this node into....
3065 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3066 (Leading _ in Macro Names, Backslash-Newline-Newline):
3067 (Backslash-Newline Comments, Long Lines in Makefiles):
3068 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3069 (obj/ and Make, make -k Status, VPATH and Make):
3070 (VPATH and Double-colon, $< in Explicit Rules):
3071 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3072 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3073 New nodes, resulting from splitup of Limitations of Make.
3074 All cross-references changed. Raise the top node from
3075 a section to a chapter, and all subnodes accordingly.
3076 Redo the introductory wording to match the new organization.
3077 (Installation Directory Variables): Use an example that is
3078 closer to what Autoconf actually does. Mention that VPATH's
3079 value should not contain metacharacters or white space.
3080 (Fortran Compiler): Fix a VPATH bug in an example.
3081 (Leading _ in Macro Names): Mention that this problem is no longer
3082 of practical concern.
3083 (VPATH and Make): Reword the advice to make it clearer
3084 that Autoconf and Automake support VPATH in non-GNU make, but
3085 many packages have bugs in this area.
3086 ($< in Explicit Rules): Refer to Build Directories rather
3087 than using a (non-VPATH-safe) example.
3088 (Automatic Rule Rewriting): Mention the sort of disaster that
3089 can ensue with Solaris-style rule rewriting with VPATH.
3091 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3093 * doc/install.texi (Compilers and Options): Weaken the
3094 suggestion to use GNU make for VPATH builds.
3096 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3097 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3099 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3100 in regular expression.
3102 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3104 * doc/autoconf.texi (Installation Directory Variables):
3105 Drop extra @samp from `@table @samp' item.
3106 (Limitations of Usual Tools): Comment fix.
3107 Do not nest @samp just to point to other table items.
3108 (Writing testsuite.at) <AT_CHECK>: The second argument to
3109 `@dvar' is already @samp'ed.
3110 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3111 do not use @var in the second argument.
3113 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3115 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3116 $as_shell.exe too. Problem reported by Andreas Buening in
3117 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3119 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3121 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3122 `unused variable' compiler warning, for `-Wall -Werror'.
3123 Reported by Jaap Haitsma in
3124 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3126 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3128 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3129 case the compiler dumps core. Problem reported for
3130 OpenServer 5.0.7 by Tim Rice in
3131 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3132 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3133 Likewise.
3135 2006-06-06 Tim Rice <tim@multitalents.net>.
3137 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3138 "ERROR" only shows up in "make check" output if there is an
3139 error.
3141 2006-06-06 Eric Blake <ebb9@byu.net>
3143 * tests/tools.at (automatically allowed tokens): Fix typo.
3145 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3147 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3149 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3150 typically overflows on x86 CPUs, even though the C standard
3151 requires otherwise.
3153 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3155 * configure.ac (AC_INIT): Bump to 2.59e.
3156 * NEWS: Update.
3158 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3160 Version 2.59d.
3162 * config/texinfo.tex: Sync from upstream.
3164 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3165 seen, invoke libtoolize with `--ltdl' argument.
3166 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3167 * NEWS: Update.
3168 Suggested by Eric Blake.
3170 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3172 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3173 reported by Ralf Wildenhues.
3174 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
3176 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3190 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3191 to...
3192 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3193 AT_CHECK_M4.
3194 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3195 `expout' as the last parameter.
3196 * tests/tools.at: Adapt to the above change.
3198 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3200 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3201 information about race-free implementations of mkdir.
3203 2006-06-04 Eric Blake <ebb9@byu.net>
3205 * bin/autoreconf.in (help): Document M4 environment variable.
3206 * bin/autoconf.as (Usage): Likewise.
3207 * bin/autom4te.in (help): Likewise.
3208 * doc/autoconf.texi (autom4te Invocation): Likewise.
3210 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3212 * NEWS: GNU make now recommended for VPATH builds.
3213 Mention that some macros are now documented to be obsolescent.
3214 * doc/autoconf.texi:
3215 Prefer "current" to "modern" to describe
3216 currently-used (albeit perhaps old-fashioned) hosts.
3217 Mention which ancient features no longer need to be worried about.
3218 setgid -> set-group-ID
3219 setuid -> set-user-ID (these are the Posix terms)
3220 Fix some misuses of "only".
3221 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3222 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3223 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3224 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3225 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3226 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3227 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3228 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3229 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3230 Mention that these macros are obsolescent.
3231 (Installation Directory Variables): shall -> should
3232 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3233 Mention that it's now safe to use 3 and 4.
3234 (Limitations of Usual Tools): cp -r is now specified by Posix.
3235 Omit longwinded and obsolescent discussion of cp -f.
3236 Modernize discussion of expr, ls.
3237 (Limitations of Make): Modernize discussion of VPATH builds.
3238 Mention $? as a workaround in some cases.
3239 * doc/install.texi (Basic Installation):
3240 Mention "./configure; make; make install" first. Be more
3241 specific about why this file is generic. Remove unnecessary
3242 parens. Remove misleading "only". Remove obsolete advice
3243 about csh. Don't say "configure" takes awhile; say it
3244 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3245 and CC=c99 rather than CC=c89, as these are blessed by current
3246 Posix. Recommend GNU make if doing a VPATH build.
3248 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3250 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3251 examples involving shell prompts.
3253 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3254 and Paul Eggert <eggert@cs.ucla.edu>
3256 * doc/autoconf.texi (Here-Documents): Add details about the
3257 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3258 use "here-documents" instead of "here documents".
3260 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3262 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3264 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3266 * doc/autoconf.texi (File System Conventions): Warn about ":"
3267 anywhere in directory names.
3269 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3271 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3272 about quoting the case statement, just in case.
3273 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3274 was fixed in ksh93g; reported by Ralf Wildenhues.
3276 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3278 * doc/autoconf.texi (System Services): Do not document
3279 overriding EXEEXT via ac_cv_exeext=ext.
3280 (Particular Programs) <AC_PROG_MKDIR_P>:
3281 Document that ${MKDIR_P} understands --.
3282 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3283 comment.
3285 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3287 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3288 argument with leading hyphen. Problem reported by Paul Eggert.
3290 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3292 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3293 about quoting ac_try: quote all of it, if any of it seems suspicious.
3294 This means we don't have to worry about ${ or sed any more.
3295 Also, double-quote the case statement, to work around misuses via
3296 underquoting as reported by Ralf Wildenhues in
3297 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3298 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3299 undocumented and dangerous macro.
3300 Problem reported by Ralf Wildenhues in
3301 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3303 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3305 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3306 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3307 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3309 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3311 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3312 since evidently some packages rely on the old, broken behavior.
3313 Problem reported by Ralf Wildenhues in
3314 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3315 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3316 pre-2006-05-26 definitions, but leave in the comments that
3317 these macros are dangerous and should not be used.
3318 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3319 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3320 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3321 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3322 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3324 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3326 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3327 the use of 'tr', since this is our only use of 'tr'.
3329 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3330 and Paul Eggert <eggert@cs.ucla.edu>
3332 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3333 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3335 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3337 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3338 the output file in the `${datarootdir}' test.
3340 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3341 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3343 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3344 mention of `datarootdir' in the input file(s), but literal
3345 `${datarootdir}' in the output file, and we haven't warned yet,
3346 then warn as well: the user may have (erroneously) used
3347 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3348 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3349 * tests/torture.at (datarootdir workaround): Extend this test.
3350 * NEWS: Update.
3352 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3353 and Paul Eggert <eggert@cs.ucla.edu>
3355 * doc/autoconf.texi (autoheader Invocation): The first argument to
3356 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3357 alternatives and clear up the language a bit.
3359 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3361 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3362 ac_config_guess, ac_config_sub, ac_configure.
3363 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3364 Fix typo that prevented an unnecessary space from being removed.
3365 Problems reported by Ralf Wildenhues in:
3366 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3368 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3370 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3371 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3372 Don't use the term "thread-safe" to talk about mkdir race
3373 conditions, since the problem is more a process than a thread
3374 issue. Problem reported by Stepan Kasal in:
3375 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3376 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3377 the test for 'install' more closely. Look at MKDIR_P first.
3378 Look in the PATH, and at /opt/sfw/bin.
3379 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3380 Don't bother to try mkdir -p, since we already check mkdir --version;
3381 just look at the version number. (There's no easy way to check
3382 for race-free implementations.)
3383 * tests/tools.at (autoconf: subdirectories): Adjust to above
3384 changes, since MKDIR_P now might end in "/mkdir -p".
3386 * doc/autoconf.texi (autoheader Invocation): Mention that the
3387 first arg of AC_DEFINE_UNQUOTED must be a literal.
3388 Problem reported by Ben Pfaff in
3389 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3391 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3392 * doc/autoconf.texi (Special Chars in Variables): New section.
3393 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3394 (Installation Directory Variables): Quote $(datadir) better.
3395 (Limitations of Builtins): Describe some of eval's trickiness.
3397 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3398 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3399 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3400 in front of every arg, not just trailing args. Quote apostrophes.
3401 (_AC_EVAL_ECHO): New macro.
3402 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3403 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3404 removed.
3405 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3406 exposed by quoting of eval argument. Put the command on line line
3407 so it logs better.
3408 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3409 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3410 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3411 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3412 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3413 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3414 Use eval more safely.
3415 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3416 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3417 to be replaced.
3418 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3419 lines, exposed by quoting of eval argument.
3421 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3422 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3424 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3425 initialization of `ac_cv_exeext', do not override it if it was
3426 already set, unless it was set to `no', for compatibility with
3427 Autoconf-2.13, and comment this.
3428 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3429 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3430 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3431 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3432 Document that this test may be overridden by setting
3433 `ac_cv_exeext'.
3435 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3437 Revert these two patches:
3439 2006-04-06 Eric Blake <ebb9@byu.net>
3440 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3441 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3442 2006-04-01.
3444 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3445 Clean up _AC_COMPILER_EXEEXT* macros.
3446 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3447 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3448 ac_file to the name of the default output file and call
3449 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3450 initial `rm' of the candidate files...
3451 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3452 the same list in subsequent `rm' calls, and for the temporary
3453 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3454 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3455 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3456 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3457 no longer needed) by libtool. Make it a cache check.
3458 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3459 copied here by mistake.
3460 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3461 _AC_COMPILER_EXEEXT.
3462 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3463 _AC_COMPILER_OBJEXT directly.
3464 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3466 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3468 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3469 Fix description of how the buggy `sed' works.
3471 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3473 Sync from Automake:
3475 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3476 ENOLCK. Only mention `make -j' when applicable. Only raise
3477 fatal errors when `make -j' is involved. Improve error message.
3479 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3481 * doc/autoconf.texi (Here-Documents): We now know more about
3482 the variable expansion in here documents bug.
3483 Thanks to Tim Rice and Stepan Kasal.
3485 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3486 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3488 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3490 * tests/autotest.at (Multiline command from M4 expansion):
3491 No failure to be expected if the shell quotes newlines in
3492 commands in the `set -x' output. Report by Tim Rice.
3493 * THANKS: Update.
3495 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3497 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3498 expansion in the here-documents used by config.status, as that
3499 runs afoul of the Korn shell version M-12/28/93d bug described in
3500 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3501 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3502 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3504 2006-05-23 Jim Meyering <jim@meyering.net>
3506 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3507 Fix typo introduced with 2006-04-02 change. It reversed the sense
3508 of the test.
3510 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3512 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3513 ac_dB slightly, to save bytes in the script.
3514 Max out at 50 lines, rather than 96; this is more likely
3515 (though not guaranteed) to avoid obscure 'sed' failures.
3517 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3519 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3520 `tr -d -' as bad option argument. Work around this by deleting
3521 an unrelated character.
3522 Report by Tim Rice <tim@multitalents.net>.
3524 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3525 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3526 Stepan Kasal <kasal@ucw.cz>
3528 * doc/autoconf.texi (Particular Programs): Do not promise that
3529 we always prefer the GNU version of the program, and that we
3530 search according to PATH; both rules can have exceptions.
3531 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3532 AC_PROG_SED. Move descriptions of limitations
3533 to the Limitations of Usual Tools section.
3534 (Limitations of Usual Tools) <sed>: Mention script length
3535 limitations with Solaris /usr/ucb/sed.
3536 <grep>: Fix wording for empty alternative. Mention that -c and
3537 -l should not be combined, and that -E and -F should not be
3538 combined.
3540 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3541 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3543 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3544 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3546 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3548 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3549 AC_DEFINE is now passed to m4_pattern_allow.
3550 * NEWS: Mention that; likewise for AC_SUBST.
3551 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3552 the parameter to m4_pattern_allow.
3553 * tests/tools.at: Add a check for that.
3555 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3557 * lib/autoconf/status.m4: Fix typos.
3559 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3561 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3562 only the files that this macro generates.
3564 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3566 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3567 the HP-UX sed limitation of 99 commands, labels do not count.
3568 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3569 in the comment.
3570 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3572 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3574 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3575 Import the following fix from coreutils:
3577 2006-01-13 Jim Meyering <jim@meyering.net>
3579 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3580 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3581 not double-quote uses of that variable, to accommodate the rare
3582 case in which getmntent is available in none of the libraries
3583 checked. This happens at least on FreeBSD 5.0.
3585 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3587 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3588 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3589 some other programs unwisely rely on these undocumented vars.
3590 But put in warning comments about them.
3591 Problem reported by Ralf Wildenhues in
3592 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3593 * NEWS: Document that these variables are intended to go away.
3595 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3597 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3598 and set the language to C++ (analogous to the equivalent Fortran
3599 tests).
3601 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3602 * doc/autoconf.texi (C++ Compiler): Document it.
3603 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3604 * NEWS: Update.
3606 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3608 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3609 that caused config.status to generate 100-command sed scripts; the
3610 portable limit is 99.
3612 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3614 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3615 variable `ac_d' instead of `d' to avoid infringing namespace.
3616 Report by Ralf Menzel.
3618 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3620 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3621 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3622 * tests/tools.at (autoconf: subdirectories): New test, taken from
3623 the corresponding problem report by Ralf Wildenhues in:
3624 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3626 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3627 Quote some uses of shell variables if they might suffer unexpected
3628 globbing. This doesn't fix all instances of quoting problems that
3629 I found, just the easy ones that look safe.
3630 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3631 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3632 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3633 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3634 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3635 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3636 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3637 Likewise.
3638 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3639 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3641 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3643 * bin/autoreconf.in ($help): Reword according to the manual.
3644 Suggested by Olly Betts.
3646 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3647 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3649 * bin/autoreconf.in: Pass the directory argument to
3650 `require_configure_ac'. Fix comment.
3651 * tests/torture.at (Configuring subdirectories): Expose this.
3652 Reported by Olly Betts.
3654 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3656 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3657 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3658 Automake as follows:
3660 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3661 `$configure_in' instead of `configure.in', to preserve
3662 directory component.
3664 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3666 * config/config.guess, config/config.sub, config/texinfo.tex,
3667 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3669 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3671 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3672 test for C99 conformance; (bool) 0.5 is an integer constant
3673 expression, but (bool) -0.5 is not. Problem reported by Fedor
3674 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3676 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3678 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3679 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3680 Warn about obsolete install-sh files. Remove stray sentence
3681 fragment and fix cross reference.
3682 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3683 install -d; this undoes the 2006-05-10 change.
3684 (MKDIR_P): Mark with AN_MAKEVAR.
3685 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3686 that we don't require $INSTALL to be thread-safe. Move comments
3687 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3688 of AC_PROG_INSTALL. Output a message saying that we're checking
3689 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3690 MKDIR_P instead of AC_SUBST.
3691 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3692 Special magic for MKDIR_P, too.
3693 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3694 a dnl.
3695 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3697 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3699 Sync from Automake, as follows:
3701 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3702 * config/install-sh: Initialize IFS, so field splitting isn't
3703 turned off later.
3704 * config/mkinstalldirs: Likewise.
3705 * config/missing: Remove superfluous quotes. Replace all uses of
3706 `[' by `test', for consistency, and for..
3707 * config/missing (sed_minuso, sed_output): New variables.
3708 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3709 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3710 Fixes `missing' to detect `--output' for help2man. Fixes
3711 PR automake/483. Report by Dennis J. Linse.
3712 (autom4te): Document in `missing --help'.
3714 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3716 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3717 * config/install-sh: Don't use 'path' to talk about file names,
3718 as per GNU coding standards. Close a race condition reported by Ralf
3719 Wildenhues and Stepan Kasal. There is still a race condition
3720 on hosts that predate Posix 1003.1-1992, but we can't help this.
3721 Don't mishandle weird characters like space on pre-Posix hosts.
3722 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3723 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3724 AC_PROG_MKDIR_P from AS_MKDIR_P.
3725 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3726 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3727 earlier editions are not (including Automake 1.8.3).
3728 Do not suggest mkinstalldirs for thread-safety.
3729 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3730 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3731 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3732 presence of special characters and race conditions.
3733 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3734 in Autoconf's name space.
3736 2006-05-10 Bruno Haible <bruno@clisp.org>
3737 and Paul Eggert <eggert@cs.ucla.edu>
3739 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3740 from Automake with minor changes.
3741 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3743 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3745 * config/install-sh: Update to Automake CVS version, as follows:
3746 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3747 * lib/install-sh: Simplify the expr implementation of dirname.
3748 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3749 * lib/install-sh: Handle --, and diagnose unknown options.
3751 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3753 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3754 `./autom4te' to create `./testsuite', since the `all' target
3755 will ensure its presence, but `installcheck' should not create
3756 the uninstalled wrappers.
3758 * tests/torture.at (Unusual Automake input files): Skip if we
3759 detect automake < 1.8.
3761 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3763 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3764 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3765 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3766 * NEWS: Update.
3768 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3770 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3771 munge (multiple) white space and other oddities.
3772 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3773 single quotes in variable assignment.
3774 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3775 and similar failures by adding multiple spaces, tabs, and other
3776 special characters.
3777 Report and different test suggested by Francesco Romani
3778 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3780 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3781 single quotes, we only need to search for single quotes; this
3782 both simplifies the search pattern, and makes us less
3783 susceptible to `echo' variations for arguments not containing
3784 single quotes.
3785 (_AC_ARG_VAR_VALIDATE): Likewise.
3787 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3789 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3790 `$*' and IFS concatenation issue with traditional shells and
3791 bash-2.04. Report by Seanster@Seanster.com.
3793 2006-05-03 Bruno Haible <bruno@clisp.org>
3795 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3796 precisely which Mac OS X versions have the od problem.
3798 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3800 * doc/autoconf.texi: Use @option systematically.
3802 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3803 and Bruno Haible <bruno@clisp.org>
3805 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3806 about 'od'.
3807 (Integer Overflow): Mention the special case of integer division
3808 overflow.
3810 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3812 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3813 traditional shells like the Solaris one that do not use the
3814 first IFS character for assembling `$*'.
3815 Prompted by a related report from autoconf_bug@nro.ca.
3817 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3818 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3820 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3821 Mention more problems with the -e option.
3823 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3825 * NEWS: Typo.
3826 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3828 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3829 in URLs to improve DVI formatted output (requires texinfo 4.6).
3830 (System Services, Systemology, Shellology): Likewise.
3831 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3832 output.
3834 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3835 continuous text.
3836 (Runtime): Fix macro argument names to match description:
3837 `action-if-found' -> `action-if-true' and similarly.
3838 (Obsolete Macros): Likewise.
3839 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3840 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3841 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3843 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3845 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3847 * ChangeLog: Typo.
3848 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3849 DVI output.
3851 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3853 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
3854 /bin/sh set unsorted output.
3855 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3856 * tests/local.at: Likewise.
3858 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3860 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3861 (Integer Overflow, Null Pointers, Buffer Overruns):
3862 (Floating Point Portability, Exiting Portably): New sections.
3863 (Writing Test Programs): Fix some langauge. Recommend exiting
3864 with status 1, not merely nonzero. Clarify exit declaration.
3865 (Run Time): Move C exit status stuff to new Exiting Portably section.
3866 (Systemology): Mention Posix and levenez. Update v7 reference.
3867 (Portable Shell): Mention the Posix shell.
3869 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3871 * bin/autoconf.as (me): Replace by as_me.
3873 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3875 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3876 since as_me isn't set yet.
3878 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3880 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3881 a few minor bugs in this area.
3883 * doc/autoconf.texi (Programming in M4sh): Comment out the
3884 documentation of AS_BASENAME, for now.
3885 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3886 (Limitations of Builtins) <basename>: Do not refer to
3887 AS_BASENAME.
3888 * bin/autoconf.as (me): Don't use AS_BASENAME.
3889 (dir): Remove the unused variable.
3890 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3891 AS_DETECT_REQUIRED. All uses changed.
3892 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
3893 All uses changed.
3894 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3895 (AS_BASENAME): Use "basename --" to protect against leading "-".
3896 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3897 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3898 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3899 (_AS_DIRNAME_PREPARE): Likewise.
3900 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3901 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3902 (AS_DIRNAME): Use "dirname --".
3904 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3906 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3907 of "run time" and "run-time" changed to "runtime", for consistency.
3908 * lib/autoconf/fortran.m4: Likewise (in comment).
3909 * lib/autoconf/functions.m4: Likewise.
3910 * lib/autoconf/general.m4: Likewise.
3911 * lib/autoconf/headers.m4: Likewise.
3913 * doc/autoconf.texi (Run Time): Document the exit status situation
3914 with more accuracy and detail.
3916 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3918 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3919 Archive is not officially `GNU' any more. Update URL.
3920 (Defining Directories): Likewise
3921 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3923 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3925 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3926 newline from the `trap' code to finish `config.log'; the NetBSD
3927 /bin/sh resets the exit status after an empty command, as
3928 documented in doc/autoconf.texi.
3929 Reported by Dalibor Topic <robilad@kaffe.org>.
3931 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3933 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3934 Suggested by Bruno Haible.
3936 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3938 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3939 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3940 Instead, just list the shells that we know work.
3941 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3942 changed. Be more cautious about the _cv_ variable.
3943 * tests/tools.at (Syntax of the shell scripts): Check the
3944 _cv_ variable once, at first, to avoid an internal autoconf error
3945 when sh -n does not work.
3947 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3949 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3951 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3953 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3954 use ">&-" since we're only 99.999% sure that this is portable,
3955 and since the MinGW bug is fixed in a different way.
3956 * lib/autotest/general.m4 (AT_INIT): Likewise.
3958 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3960 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3961 before opening config.log, to avoid hitting a bug on MinGW.
3963 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3965 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3966 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3967 This works around a MinGW bug reported by Eric Paire.
3968 Make sure that all writes to the log file append to it,
3969 rather than possibly losing data.
3970 * lib/autotest/general.m4 (AT_INIT): Likewise.
3972 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3974 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3975 description.
3977 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3979 * NEWS: Update.
3981 * configure.ac (AC_INIT): Bump to 2.59d.
3983 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3985 Version 2.59c.
3987 * Makefile.maint (news-date-check): Do not require a leading `*'
3988 before the release date in NEWS.
3990 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3991 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3993 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3994 the instantiated file do not contain the string 'datarootdir'
3995 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3996 @mandir@, replace the reference '${datarootdir}' by the value.
3997 * tests/torture.at (datarootdir workaround): New test.
3998 * NEWS: Advertise this temporary fixup.
3999 Based on a patch by Bruno Haible, reported and analyzed by
4000 Paul Eggert and Noah Misch.
4002 2006-04-12 Eric Blake <ebb9@byu.net>
4004 * tests/autotest.at (Debugging a failed test): Fix comment.
4006 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4008 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4009 all the changes since 2006-04-07.
4011 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4013 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4014 succeeded, but `ln -s file dir' failed, take care to remove the
4015 leftover target before the next test, to prevent its spurious
4016 failure; also make sure `ln file dir' works before selecting it.
4017 Thanks to Keith Marshall for pointing this out.
4018 * THANKS: Update.
4020 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4021 assignments in `at_debug_args', so that we put them correctly
4022 in the `run' script.
4023 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4024 Reported by Eric Blake.
4026 2006-04-11 Eric Blake <ebb9@byu.net>
4028 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4029 top-level tests after micro-suite has been run. Used in...
4030 (Debugging a successful test, Debugging script and environment),
4031 (Debugging a failed test): ...these new tests. The first of these
4032 is fixed by...
4033 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4034 macro, split out from...
4035 (AT_INIT): ...here, so that using -d also generates a run script.
4036 Document that -d inhibits top-level logging.
4037 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4038 inhibits top-level logging; debug scripts are created.
4040 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4041 check.
4042 * tests/autotest.at (Empty test, Empty check): New test to check it.
4044 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4045 from gcc.
4047 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4049 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4050 the files if a problem appears. Make the empty *.at files
4051 read-only, too. Proposed by Ralf Wildenhues.
4053 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4055 * config/Makefile.am: Add comment to force updated Makefile.in.
4057 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4058 space only patch to this file, this patch causes the Makefile.in
4059 files that include freeze.mk to be updated, and thus have a
4060 newer time stamp again, which in turn makes a pristine CVS
4061 checkout have correct time stamps.
4063 * Makefile.maint (cvs-sv): New macro, to be used..
4064 (config.guess-url_prefix, config.sub-url_prefix)
4065 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4066 point to CVS text checkout of Gnulib files.
4067 (copyright-check): Bump current year.
4068 (announcement): Do not hard-wire `./announce-gen'.
4069 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4070 correctly.
4071 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4072 `chmod +x'.
4073 (wget_files): Update config.guess, config.sub, texinfo.tex by
4074 `wget-update', now that their URLs work again.
4076 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4078 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4079 Problem noted by Paul D. Smith.
4081 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4083 * doc/autoconf.texi: Remove unused words from word list.
4084 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4085 .x-sc_trailing_space: New files.
4087 * doc/standards.texi: Sync from gnulib.
4089 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4090 `LIBOBJDIR' as experimental.
4092 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4093 with a target directory; it's internally implemented as `cp'
4094 anyway, but since Autoconf advertises the possibility to use
4095 a target directory when LN_S is `ln -s', we need to find out.
4096 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4097 analyzed by Keith Marshall <keith.marshall@total.com>.
4099 * THANKS: Update.
4101 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4103 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4104 confdefs.h as-is. In general, if it has backslash-newline or the
4105 like, then it doesn't work either to sort or to remove empty
4106 lines.
4108 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4110 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4112 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4114 * lib/autom4te.in (Automake-preselections): Preselect
4115 _AM_SUBST_NOTMAKE.
4117 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4119 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4120 apostrophe within a single-quoted string, as this is the usual
4121 tradition and is easier to read than '"'"'. Don't rely on the
4122 shell treating "$/" like '$/'. Use a more-consistent indenting
4123 style for the trap.
4125 2006-04-09 Eric Blake <ebb9@byu.net>
4127 * tests/autotest.at (Backquote command substitution),
4128 (Multiline backquote command substitution): Remove mistaken
4129 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4130 applied...

4212 _AS_DETECT_BETTER_SHELL:
4214 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4215 skip nonexistent directories.
4216 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4217 only shell candidates which exist.
4218 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4219 * lib/autotest/general.m4 (AT_INIT): No need to give three

4222 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4223 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4225 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4226 distinguish m4sugar macros.
4227 * tests/tools.at (autoupdating with aclocal and m4_include):

4229 test case by Noah Misch <noah@cs.caltech.edu>.
4231 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4233 Revert my change from 2006-03-17, in other words:
4234 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4235 and DUALCASE=1.
4236 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4237 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4238 it is set.
4240 2006-04-07 Eric Blake <ebb9@byu.net>
4242 * doc/autoconf.texi (Programming in M4sh): Document that
4243 AS_MKDIR_P exits the script on failure.
4244 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4246 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4248 * config/elisp-comp, config/install-sh, config/mdate-sh,
4249 config/missing, config/mkinstalldirs: Sync from Automake.

4265 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4267 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4268 whether `set' quotes correctly: redirect stderr of the tested
4269 `set', and use a subshell, for Ultrix; use `sed' instead of
4270 `grep' for zsh `set' which may write binary output; match only
4271 at the beginning of a line, to avoid false positives.
4272 In order to avoid false positives by unrelated variables with
4273 multiline content, put the dump algorithm in a subshell and
4274 unset all variables containing newlines (except some which are
4275 special to the shell). Warn about cache variables that are
4276 unset.
4278 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4280 * config/config.guess, config/config.sub, config/texinfo.tex:

4289 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4290 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4291 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4292 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4294 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4295 shell issue with double-quoted command substitutions of native
4296 commands.
4297 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4298 Marshall.
4300 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

4317 * tests/Makefile.am (maintainer-check-posix):
4318 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4320 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4321 ac_config_<foo>s again, sometimes normalized, sometimes not.
4322 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4323 (AC_CONFIG_COMMANDS): Do not do so here.
4324 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4325 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4326 2005-07-25 rewrite. Noticed by Noah Misch.
4328 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4329 _AC_PRESERVE_HELP_ORDER, ...
4330 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4332 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4333 inside m4_expand_once; it is redundant.
4335 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4336 for --help from Cygnus `configure.'
4338 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

4351 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4352 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4353 * doc/autoconf.texi (Help Formatting): New node.
4354 * NEWS: Announce AC_PRESERVE_HELP_ORDER.

4378 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4379 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4380 normalizing it, consistent it with previous releases.
4381 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
4383 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4385 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
4386 Use simplified args that Eric Blake originally suggested.
4388 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
4390 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4391 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4392 Use 'comm' rather than N instances of grep; this also fixes a bug
4393 whereby substrings were incorrectly matched, causing us to not
4394 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4395 (exclude_list): Exclude empty macros.

4408 a subdirectory subject to Cygnus `configure'.
4409 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
4411 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
4412 report request when we have no AC_PACKAGE_BUGREPORT.
4414 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4416 * THANKS: Update.

4479 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4480 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4481 ac_file to the name of the default output file and call
4482 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4483 initial `rm' of the candidate files...
4484 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4485 the same list in subsequent `rm' calls, and for the temporary

4488 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4489 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4490 no longer needed) by libtool. Make it a cache check.
4491 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4492 copied here by mistake.
4493 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4494 _AC_COMPILER_EXEEXT.

4528 Autoconf version number despite a zero- or one-argument AC_INIT.
4530 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
4531 subordinate tools.
4532 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4533 * doc/autoconf.texi (autoreconf Invocation): Document it.
4535 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

4547 the correct lines of the input file by subtracting..
4548 (_au__first_line): ..this new definition.
4550 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer

5268 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5269 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5270 by the function rather than ignoring it.
5271 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5272 comparing its address. Intel's interprocedural optimization was
5273 outsmarting the old heuristic. Problem reported by

5288 before removing it (chmod -R u+rwx); there are three instances of this.
5290 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5291 Stepan Kasal <kasal@ucw.cz>
5293 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5294 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5295 make its content writable before removing it. Remove an errorneous
5296 comment from the end, where the logs of the failed tests are copied
5297 to the main log file.
5299 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5301 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

5306 problems if the testsuite were running too fast.
5308 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5310 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5311 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5312 (which belong to Xt, not X itself). See Debian bug 327655.
5313 * NEWS: Mention this.
5315 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5317 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5319 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5321 * config/move-if-change: Don't output "$2 is unchanged";
5322 suggested by Ben Elliston. Handle weird characters correctly.
5324 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5326 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5327 calls, so that the final expansion of this macro is shorter.
5328 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5329 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5330 the cleanup there. Use AS_VAR_* macros, to be more general.
5331 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5333 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5335 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

5348 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5350 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5351 The previous patch didn't work, so try a better one.
5353 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5355 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5356 in the example. Reported by Bruno Haible.
5357 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5358 "if $undefined_var;" succeeds with my shell.
5360 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5361 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5362 but change the m4_divert_text to m4_divert_once.
5364 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5366 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5367 Work around bug in Solaris /usr/xpg4/bin/awk.
5368 The bug is present in at least Solaris 8 through 10.

5372 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5373 some evil values and relying on the fact that $* concatenates the
5374 parameters by the first character from IFS.
5376 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5377 Stepan Kasal <kasal@ucw.cz>
5379 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5380 first header appears, define AH_HEADER.
5381 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5382 Update limitations about when to call AC_CONFIG_HEADERS.
5383 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5384 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5385 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5386 ``Configuration Actions''; fix their index entries.
5388 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5389 options correctly. Process N-M as M-N if M is smaller than N.
5390 Process ranges correctly so that N-N will run only N.
5391 Sort and uniquify the tests that will be run. If there is more
5392 than one test, reinsert the banners for the tests.

5398 before passing the macro name to AH_TEMPLATE.
5400 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5401 now opens log after option processing; in particular, --version
5402 and --help do not touch config.log.

5414 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
5415 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5416 Language cleanup.
5418 * doc/autoconf.texi (Defining Symbols, Changed Results):
5419 Prepend to LIBS, not append, in examples.
5421 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5423 When building in place, set srcdir="."; suggested by Tim Van Holder.
5425 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5426 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5427 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5428 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5429 does not mean "no --srcdir option".
5431 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5433 * tests/autoscan.at (autoscan): New file.
5434 * tests/suite.at: Use it.
5435 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
5436 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5438 * tests/autotest.at (Keywords): Test keywords combinations.
5440 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5442 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5443 add "2>&1"; gzip 1.2.4 prints help on stderr.
5445 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5447 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5448 was pushdef'ed twice while popped only once. Push it only once.
5449 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5451 2005-07-26 Stepan Kasal <kasal@ucw.cz>

5460 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5461 "<tab>" in comment, so that the point is understandable.
5463 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5465 Rewrite substantial part of lib/autoconf/status.m4.
5466 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5467 and CONFIG_COMMANDS are not processed in four separate loops.
5468 Instead, there is one main loop. This alows that the common code
5469 is expanded only once, thus config.status (and configure) is smaller.
5471 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5472 the AC_LIST_FILES and cousins macros are no longer used.
5474 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5475 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5476 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5477 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5478 contain the initialization, nor the for loop, nor the associated
5479 commands; all these go to ...
5480 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5481 _AC_OUTPUT_CONFIG_STATUS.
5482 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5483 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5484 (_AC_OUTPUT_FILE): The creation of the sed script ...
5485 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5486 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5487 _AC_OUTPUT_MAIN_LOOP.
5488 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5489 _AC_CONFIG_COMMANDS): Use ...
5490 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...

5496 ... new macros.
5497 (_AC_CONFIG_UNIQUE): Update.
5498 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):

5503 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5504 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5505 this didn't belong to the `config commands' section.
5506 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5507 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5508 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5509 to the `config commands' section either.
5510 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5511 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.

5525 parameter to AC_DIAGNOSE.
5526 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.

5528 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5529 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5530 with AU::AC_OUTPUT.
5531 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5532 in AC_OUTPUT doesn't double-quote it either.
5533 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5534 parameters.

5558 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5559 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5560 (AC_ARG_VAR): ... here.

5571 a loop to assign all ac_env_* and ac_cv_env_* variables.
5572 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5573 to INIT_PREPARE.
5574 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5575 its value to shell variable ac_precious_vars and call
5576 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5577 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5578 _AC_ARG_VAR_VALIDATE.

5616 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5618 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

5623 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5624 sed substitution command, so that we allow | in program prefixes

5627 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5628 configure_input, top_builddir, srcdir, etc.
5629 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5630 PATH_SEPARATOR in AUTOTEST_PATH.
5632 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

5640 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5641 directories with weird names. Apparently some people like living

5662 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5663 document to output the default config_* lists to config.status.
5664 Don't recognize option --file, if the functionality is not there.
5665 Likewise for --header; moreover, recognize --he and --h as shortcuts
5666 for --help in that case.
5668 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5669 matches the order of execution. No code changed.

5691 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5692 (AC_SUBST): Call it.
5693 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5694 the directory specific variables; but don't call it for configure_input.
5696 2005-06-28 Derek Price <derek@ximbiot.com>
5698 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5699 addition.
5701 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5703 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5704 directory have inherent problems with special characters like spaces,
5705 due to limitations in Make syntax. Problem reported by Alexandre
5706 Duret-Lutz.
5707 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

5722 variable into diagnostic. Make the diagnostic an error, not a warning,
5723 because we really don't support spaces and suchlike in dir names.
5724 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5725 Don't worry about backslashes in srcdir; it can't happen now.
5726 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5727 Simplify ac_optarg handling.

5742 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5744 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

5752 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5753 b, t, r, w commands require single space, while : cannot have any.
5754 (Special Shell Variables): Fix sed code this in the example.
5755 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5756 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5758 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5759 expand to the empty list. Don't use two pairs of m4_changequote,
5760 it's not necessary.
5762 2005-06-20 Derek Price <derek@ximbiot.com>
5764 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

5768 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5769 * doc/autoconf.texi:
5770 Don't mention Solaris versions so much, if a
5771 problem is common to all extant versions of Solaris. Say "SunOS
5772 4" instead of "SunOS" for SunOS 4.
5773 (awk): Mention more of the limitations of traditional Awk.
5774 (cat): Don't talk about cat -v.
5776 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

5784 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5785 on Mac OS X 10.4 reported by Peter O'Gorman in:

5787 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5788 Use shell builtins rather than 'expr', to work around expr bug.
5790 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5792 * doc/autoconf.texi: "filesystem" -> "file system".
5793 "behaviour" -> "behavior".

5806 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5807 quotes and backslashes. Patch from Derek Price.

5814 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5816 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5817 -u, since it outputs chatter if the input files are the same.
5818 Problem reported by Ralf Menzel.
5820 2005-06-08 Derek Price <derek@ximbiot.com>
5822 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5823 renaming them since they are about to be redefined anyhow.
5825 2005-06-08 Derek Price <derek@ximbiot.com>
5827 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5828 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5829 Move m4_undefine to alphabetical order.
5831 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5833 * README: Recommend GNU M4 1.4.3 or later.
5834 * doc/autoconf.texi (Introduction): Likewise.
5835 Reword to avoid some formatting glitches.
5836 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5837 Clarify explanation of HP compiler bug.
5838 Redo example output tp match current CVS snapshot.
5839 Use @example.org in email addresses when the examples
5840 might get inadvertently cut-and-pasted into user code.
5841 Remove example of autom4te usage that doesn't seem to work now.
5842 Use modern AC_INIT (except when the example is meant to be
5843 shown with Autoconf 2.13).
5844 Update ksh info for Solaris 9 and later.
5845 KB -> kB.
5846 Modernize description of Automake versions a bit.
5847 Don't claim a future version of Autoconf is near.

5854 Reword to avoid some formatting glitches.
5855 * doc/installt.exi: Reword to avoid some formatting glitches.
5857 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5858 Tru64 ksh pattern matching bug. Reported against Libtool by
5859 Albert Chin <libtool@mlists.thewrittenword.com> and
5860 Nicolas Joly <njoly@pasteur.fr>.
5862 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5864 m4_cdr of one-member list was [[]] (one-member list containing an
5865 empty string) instead of [] (an empty list. Callers were skewed to
5866 match this misbehaviour. As a consequence of this:
5867 - m4_foreach([x], [], [foo]) expanded to `foo', while
5868 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5869 This bug has been fixed:
5871 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5872 expand to an empty string; print error msg if called without
5873 an argument list.
5874 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5875 misbehaviour; handle [] and [[]] correctly.

5883 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5885 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5886 swallow records with more than 99 fields.
5887 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5888 parse the long line.
5890 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5892 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5893 swallow literals longer than 399. Reported by Ralf Wildenhues.
5894 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

5897 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5899 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5900 to gfortran, and make these the first two compiler names
5901 checked (following the general autoconf preference for gcc).
5903 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5905 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5906 (DISTCLEANFILES): Remove $(check_SCRIPTS).

5911 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5912 expression of unbounded size when processing the --list
5913 option. This runs afoul of a limit of 399 bytes per regular
5914 expression on AIX. Problem reported by Ralf Wildenhues.

5925 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5927 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5928 now contain newlines, and substituted files must be referenced on
5929 a line alone; the sed scripts to substitute them are now very
5930 different.
5931 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5932 commands can be put in a sed script portably.
5933 * doc/autoconf.texi (Setting Output Variables): Document above

5941 From Ralf Menzel (trivial change).
5943 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
5945 * tests/local.at: Don't attempt to check for negated character
5946 classes in shell scripts. The test was too brittle.
5948 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5950 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5951 * doc/autoconf.texi (Limitations of Builtins): Document this
5952 limitation.
5954 2005-05-24 Stepan Kasal <kasal@ucw.cz>
5956 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
5957 common code; used in many places in the tree.
5958 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
5959 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
5961 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
5963 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
5964 messages when ac_unique_file is not found.
5965 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5966 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5967 commands, for consistency with AC_MSG_ERROR and such.
5969 * bin/autoconf.as: Make more use of "shift 2" in option processing.
5971 * bin/Makefile.am: Merge the two rules for creating scripts.
5973 2005-05-23 Stepan Kasal <kasal@ucw.cz>
5975 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
5976 obsolete; it was never documented.
5977 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
5979 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5981 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5982 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5983 (ac_top_builddir): ... this ...
5984 (ac_top_build_prefix): ... to this; the old name is also kept, for
5985 backward compatibility.
5986 (ac_top_builddir_sub): New variable, without the trailing slash,
5987 always nonempty.
5988 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5989 * doc/autoconf.texi (Configuration Actions): Rename
5990 ac_top_builddir to ac_top_build_prefix.
5991 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5992 at_top_builddir to at_top_build_prefix.
5993 * lib/autotest/general.m4 (AT_INIT): Likewise.
5995 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5997 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5998 of confdefs.h .
6000 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6002 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6003 argument to m4_foreach. I guess it was necessary in the past,
6004 but I think it's a no-op now.
6006 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6008 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6009 ``cat <<_ACEOF'' commands to one.
6010 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6011 * lib/autoconf/status.m4: On various places, use expr instead of
6012 ``echo|sed.''
6013 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6014 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6015 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6016 a range.
6017 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6018 the wrong patterns between ``case'' and ``esac.'' The previous
6019 code had false positives.
6021 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6023 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
6024 as on 2005-05-02.
6025 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
6026 Mention LIBOBJDIR.

6066 2005-05-13 Stepan Kasal <kasal@ucw.cz>
6068 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
6069 check.
6070 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
6071 enough arguments, similarly as in m4_bpatsubsts.
6073 2005-05-12 Stepan Kasal <kasal@ucw.cz>
6075 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
6076 of absolute paths.
6078 2005-05-11 Stepan Kasal <kasal@ucw.cz>
6080 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6081 for absolute directory names in one loop.
6082 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
6083 abbreviations of --version and --debug.
6085 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6087 * doc/autoconf.texi (Autoconf Language): Be more precise about
6088 quoting rules. Problems noted by Stepan Kasal.
6089 Also, throughout this document, be more careful about white space.
6090 "blank", "white space", and "space" all have different meanings
6091 and we should be careful to say what we mean.
6093 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6095 Fix C++ related problems reported by Werner Lemberg.
6096 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
6097 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
6098 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6099 avoid problems with C++ and throw.
6100 * tests/compile.at: .cpp, not .cc.
6102 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6104 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6106 * doc/autoconf.texi (Generic Functions): Typos.
6108 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6110 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6111 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6112 set by latest automake.
6114 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6116 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6117 outputs 0 on GNU/Linux these days.
6119 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6121 * doc/autoconf.texi (Autoconf Language): Add more description
6122 about quoting heuristics.
6123 (Limitations of Builtins): Describe "set -" problems.
6125 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6127 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6128 not newline.
6130 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6131 by AC_DEFINE; it was a mistake.
6132 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6134 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6136 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6138 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6140 * doc/autoconf.texi (External Software): Quadrigraphs are not
6141 processed correctly in AS_HELP_STRING; avoid this in the examples.
6142 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6143 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6144 comment and reduce m4_default([foo], []) to [foo].
6145 (m4_strip): Update the explanation.
6147 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6149 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6150 Remove core.conftest.* too; it's generated by Tru64 5.1.
6151 Problem reported by Jennis Pruett.
6152 * lib/autoconf/functions.m4
6153 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6154 Don't bother to remove core files; AC_RUN_IFELSE should do that
6155 for you.
6157 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6159 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6161 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
6163 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
6164 Report from Horst Wente.
6166 2005-04-15 Stepan Kasal <kasal@ucw.cz>
6168 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
6169 the comment.
6171 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
6173 * doc/autoconf.texi (External Software, Package Options): Add
6174 examples showing how to implement --with-* and --enable-* options.
6176 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6178 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6179 as well as configure.in. Problem reported by Gregorio Guidi.
6181 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6183 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6184 pattern for alloca snippet.
6186 2005-04-04 Stepan Kasal <kasal@ucw.cz>
6188 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
6190 2005-04-01 Stepan Kasal <kasal@ucw.cz>
6192 * doc/autoconf.texi (Generic Programs): Fix a typo.
6194 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
6196 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6197 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6199 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6201 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6202 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6203 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6204 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6205 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6207 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6209 * NEWS: The configure command now warns you if you attempt to use
6210 a directory whose name contains a special character like space,
6211 newline, or "\".
6212 * doc/autoconf.texi (Installation Directory Variables): Allow
6213 "," in file names. Do not use \@; it's not a portable regexp.
6214 * bin/Makefile.am (edit): Likewise.
6215 * lib/Makefile.am (edit): Likewise.
6216 * tests/Makefile.am (edit): Likewise.
6217 * tests/semantics.at: Likewise.
6218 * tests/torture.at: Likewise.
6219 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
6220 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6221 * doc/autoconf.texi (File System Conventions): Warn about
6222 unportable file names.
6223 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6224 (AC_INIT): Use it.
6225 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6226 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6227 ac_pwd, and quote srcdir.
6228 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6230 * doc/autoconf.texi: Fix some systematic formatting problems.
6231 ".)" needs a following @: if not at the end of a sentence, and
6232 similarly for "!)". "etc." should be preceded by a comma.
6233 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6235 2005-03-22 Bruno Haible <bruno@clisp.org>
6237 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6238 argument is often called 'build-aux'.
6240 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6242 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6243 macro AC_TRY_LINK is obsolete.
6244 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6245 `AC_CONFIG_FILES'.
6247 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6249 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6250 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6251 from a Common Lisp's `cl'.
6252 (AC_PROG_CXX): Behave according to the documentation: don't
6253 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6254 make the variable CCC precious; use `cl.exe', not `cl'.
6256 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6257 Alexandre Duret-Lutz <adl@gnu.org>
6259 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6260 /dev/null, as "configure" shouldn't read stdin, and this insulates
6261 us from problems (e.g., when testing for "cl"). Also, do this
6262 redirection before invoking "hostname" or "uname", and keep the
6263 original input stream available via...
6264 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6265 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6266 bother with "</dev/null" since it's now done at the top of
6267 'configure'.
6268 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6269 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6270 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6271 * doc/autoconf.texi (File Descriptor Macros): New section.
6272 (Printing Messages): Mention it.
6273 * tests/base.at (Input/Output): New test.
6275 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6277 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6278 newline if neither \c nor -n work, as that would output two
6279 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6281 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6283 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6284 This causes that any required macros inside will get before the if.
6285 * doc/autoconf.texi (autom4te.cache): A typo.
6287 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6289 Undo previous change, except keep the change to
6290 lib/autoconf/programs.m4 that replaced grep with shell
6291 pattern-matching. This is because net-snmp configure reads stdin.
6292 Reported by Noah Misch.
6294 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6296 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6297 from /dev/null, as "configure" shouldn't read stdin, and this
6298 insulates us from problems (e.g., when testing for "cl").
6299 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6300 before invoking "hostname" or "uname".
6301 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6302 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6303 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6304 "</dev/null" since it's now done at the top of 'configure'.
6305 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6306 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6307 Also, replace grep with shell pattern-matching, to save a process.
6309 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6311 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6312 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6313 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6314 compiler.
6316 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6318 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6319 grep -q isn't portable. Improve grep -s explanation.
6320 Problem reported by Dan Manthey.
6322 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6324 * doc/autoconf.texi (Special Shell Variables): Clarify
6325 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6327 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6329 * doc/autoconf.texi: Use @acronym for DJGPP.
6330 Fix some @code's that should have been @env's, and vice versa.
6331 Sort environment variable names.
6332 Mention that shells no longer inherit IFS.
6333 Don't recommend PATH_SEPARATOR=';' so strongly.
6334 Mention that $RANDOM might expand to the empty string.
6335 "symlink" and "soft link" -> "symbolic link".
6336 Improve mktemp description (reported by Bruno Haible).
6338 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6340 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6341 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6342 Likewise.
6343 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6344 Likewise.
6346 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6348 * NEWS: Mention AT_COPYRIGHT.
6350 * tests/local.at (AT_CMP): Use diff directly on input files rather
6351 than copying them.
6353 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6354 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6356 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6357 and Paul Eggert <eggert@cs.ucla.edu>
6359 * tests/autotest.at (Empty test suite): New test.
6360 * tests/torture.at (Substitute and define special characters)
6361 (Substitute a 2000-byte string, Define to a 2000-byte string)
6362 (Substitute a newline, Define a newline): New tests.
6364 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6366 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6367 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6368 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6369 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6370 (Standard regular expressions): New test.
6371 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6372 excess test name quoting.
6373 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6374 CPPFLAGS to `configure' instead of setting it in `configure'.
6376 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6377 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6378 on some platforms.

6412 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6414 Try not to generated lines of unlimited length, as POSIX places a
6415 2047-byte limit on line length of portable text files.
6416 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6417 Use newline as a separator, not space.

6475 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6476 Update the long comment explaining it.
6478 m4_require no longer writes an ``is required by'' line to the
6479 execution stack. It contains only one bit of non-redundant
6480 information: that the macro was required, not called. And even
6481 this bit is useless in most situations: have you ever met a macro
6482 which both calls and requires the same macro?
6484 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6485 (_m4_defun_pro_outer): ... only via this macro, for the outermost

6492 (_m4_require_call): Use it.
6493 * tests/m4sugar.at (m4_require): Expect output without the
6494 ``is required by'' messages.
6496 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6498 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6499 rather than x for expr.
6501 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6502 this is safe.
6503 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6504 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6519 config.h.in is always recreated when --force.

6525 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6527 * doc/autoconf.texi (Limitations of Builtins): Clarify that

6530 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6532 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6533 Warn about newline stripping in `` and $(). Update Solaris
6534 version to 9.
6535 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6536 X insulates us from future changes to Posix.
6537 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6538 stripping.
6540 2005-01-19 Stepan Kasal <kasal@ucw.cz>

6560 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6562 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6564 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

6586 (_m4_divert_n_stack): New macro; the expansion is
6587 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6588 otherwise.
6589 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6590 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6591 stored in _m4_divert_diversion or _m4_divert_dump.
6592 (m4_divert_pop): When the parameter is given, compare the symbolic
6593 name with the last diversion pushed on the stack. Previously, the
6594 current diversion was compared with the numeric value of the
6595 diversion given as the parameter.
6596 (m4_require): If the macro hasn't been expanded yet, call ...
6597 (_m4_require_call): this new macro.

6630 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

6632 not essential. Reported by Magnus Therning.
6633 * tests/torture.at (autoreconf.): New banner.
6634 (autoreconf and non-AC configure): Rename to `Non-Autoconf

6683 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
6684 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

6846 * doc/autoconf.texi (Libraries): Clarify problems with AC_CHECK_LIB
6847 and suggest AC_SEARCH_LIBS. Suggested by Noah Misch and Stepan Kasal.
6849 2004-12-08 Noah Misch <noah@cs.caltech.edu>
6851 * configure.ac (test suite): Cease to generate wrapper scripts.

6856 (wrapper.in): Generate it in the build directory.
6857 (MAINTAINERCLEANFILES): Delete wrapper.in.
6858 (CLEANFILES): Add wrapper.in.
6859 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
6860 the output. Replace each $as_me with a @wrap_program@.
6861 * tests/wrapper.in: Delete it; we always build it.
6863 * bin/Makefile.am (autoconf.in): Generate it in the build directory.

6876 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
6878 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
6879 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
6880 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
6881 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
6883 2004-12-07 Stepan Kasal <kasal@ucw.cz>
6885 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

6897 out the common code to ...
6898 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
6899 value of the #define--default to 1, iff the macro was called
6900 with exactly one parameter.
6902 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6904 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6905 "char c = '\200';" rather than "char c = 0x80;" as the
6906 latter doesn't conform to the strict C standard due to
6907 overflow on signed char hosts.
6909 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6910 to -qlanglvl=ansi. We don't want to disable extensions.

6970 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
6971 the $1_found variable, don't test whether the file is executable;

7010 Problem reported by Stepan Kasal.
7012 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
7014 Fix problems reported by Andreas Buening in:
7015 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
7016 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
7017 in test makefile.
7018 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
7019 readable; it's not true in OS/2-emx.
7021 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
7023 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7024 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7025 (trivial change). Problem and patch reported by Andrew Church in:
7026 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7028 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
7030 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

7055 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7056 texinfo.tex for now (done by hand now).
7057 * Makefile.maint (wget_files, cvs_files):
7058 Remove ansi2knr.c; nobody uses it.
7059 (ansi2knr.c-url_prefix): Remove.
7060 (cvs-update): Fix test for failure. I don't know why it ever
7061 worked...
7063 * doc/autoconf.texi: Update URLs, some of which went stale.
7064 Use @uref rather than @href.
7066 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7067 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7069 * config/config.guess, config/config.sub, config/elisp-comp,
7070 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7071 doc/fdl.texi, doc/standards.texi: Sync with master copy.
7073 * NEWS, TODO, configure.ac, bin/autoscan.in,
7074 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
7075 doc/install.texi, lib/Autom4te/Configure_ac.pm,

7079 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7080 tests/tools.at, tests/torture.at:
7081 Use "file name" rather than "filename" or "path",
7082 to be consistent with the terminology of the GNU coding standards.
7084 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7086 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7087 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7088 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7089 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7091 More fixes to support spaces in the name of the build directory.
7092 This isn't a complete fix but it's an improvement.
7094 * bin/autoconf.as (autom4te_options): New var.
7095 Use it instead of appending to AUTOM4TE, so that we can allow
7096 spaces in the build directory's absolute name.
7097 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7098 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

7109 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
7111 * doc/autoconf.texi (Function Portability): Document isinf and
7112 and isnan. From a suggestion by Kevin Ryde.
7114 * lib/Autom4te/General.pm (END): Return correct exit status even
7115 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7117 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7119 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7120 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7121 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7123 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7125 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7126 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7127 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7128 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7129 * lib/autom4te.in (Automake-preselections): Preselect
7130 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7132 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7134 * lib/autom4te.in (Automake-preselections): Preselect
7135 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7136 trace them.
7138 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7140 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7141 Tru64.
7142 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7143 Document problem with "`""`" in pdksh POSIX mode.
7145 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7147 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7148 with pdksh, too. Problem reported by Patrick Welche via
7149 Gary V. Vaughan.
7150 * doc/autoconf.texi (Shellology): Note that set -o posix is
7151 useful for pkdsh, too.
7153 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7155 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7156 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7157 Don't fail if ENV or BASH_ENV is readonly.
7158 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7159 etc. are read only. Problem reported by Ludovic Courtes.
7161 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7163 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7164 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7165 (trivial change)
7167 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7169 * doc/autoconf.texi (File System Conventions): Warn about
7170 names like "aux". Problem reported by Eric Blake.
7172 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7173 by zero instead of array size, so that we can use any arithmetic
7174 constant expression (instead of requiring an integer constant
7175 expression). This allows us to test expressions like DBL_MAX <
7176 LDBL_MAX, which didn't conform to the C standard using the old
7177 method.
7178 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7179 now that we can do floating-point tests at compile time.
7181 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7183 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7184 and LDBL_EPSILON, as the resulting expression isn't an
7185 integer constant expression and violates the C standard.
7186 Problem reported by Nelson H. F. Beebe. Also, check
7187 for "L" suffix, and check that long double doesn't have
7188 worse range or precision than double, that mixed-mode
7189 arithmetic doesn't generate a diagnostic, that double
7190 constants fit in long double.
7192 2004-06-03 Kevin Ryde <user42@zip.com.au>
7194 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7195 malloc(0) and realloc(NULL,size).
7197 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7198 Bob Proulx.
7200 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7202 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7203 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7204 by Jim Meyering.
7206 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7208 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7209 can be rewritten using if-then-else. Suggested by Bruno Haible.
7211 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7213 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7214 Problem reported by Stepan Kasal.
7216 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7218 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7219 change). Patch reported by Ralf Wildenhues in
7220 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7222 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7223 function F exists if the compiler and linker let you compile an
7224 expression like (F != 0). Recent versions of GCC optimize away
7225 the reference to F in that case, since every function address must
7226 be nonzero, so the link succeeds even if F does not exist.
7227 Problem reported by Manu in
7228 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7230 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7231 "Unix". Many uses changed.
7232 (Limitations of Builtins): Explain better why the ! command isn't
7233 portable.
7235 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7237 * lib/autom4te.in (Automake-preselections): Preselect
7238 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7240 2004-05-19 Kevin Ryde <user42@zip.com.au>
7242 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7243 referencing AC_FUNC_STRERROR_R.
7245 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7246 note pessimistic assumption when cross compiling.
7248 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7250 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7251 (until 2004) invoked subcommands with sh -e, contra POSIX.
7252 Reported by Kevin Ryde.
7254 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7256 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7257 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7258 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7259 `test -f " /usr/bin/grep"', which _always_ failed.
7260 (AC_PROG_SED): Ditto bogus PATH fix.
7261 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7262 requires that grep correctly supports _multiple_ `-e' options, rather
7263 than stating only that grep should accept `-e'.
7265 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7267 Port to C99, which requires that 'exit' be declared.
7269 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7270 to ensure that stdlib.h is included.
7271 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7272 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7273 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7274 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7275 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7276 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7277 when using 'exit' in a test; C99 requires that 'exit' be declared.
7279 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7281 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7282 now prefers 'grep' implementations that accept -e.
7283 (Limitations of Usual Tools): Describe problems of traditional
7284 egrep and fgrep with long input lines, and of traditional grep
7285 with -e.
7286 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7287 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7288 All callers changed. Append /usr/xpg4/bin to the PATH, for
7289 Solaris.
7290 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7291 the user with complaints about multiple -e options.
7292 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7293 Define it with AC_PROG_GREP.
7294 * configure.ac (AC_PROG_GREP): Add.
7295 * lib/freeze.mk (GREP): New macro.
7297 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7299 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7300 a possible candidate only after all others fail, rather than
7301 consulting it first. This improves backward compatibility by
7302 better reflecting the way shell selection occurred in previous
7303 versions of Autoconf, and should help to avoid triggering latent
7304 problems in other packages, such as the one in Automake where zsh
7305 is not handled robustly:
7306 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7307 Although it is not Autoconf's responsibility to work around
7308 problems in Automake, it nevertheless makes sense to avoid
7309 introducing unnecessary incompatibilites.
7311 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7312 Gary V. Vaughan <gary@gnu.org>
7314 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7315 how deeply nested we are when a suitable tool is found, set the
7316 ac_path_TOOL_found flag.
7317 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7318 nested we are in this macro. Break out of all 3 nested loops if
7319 ac_path_TOOL_found is set.
7321 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7323 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7324 of the _AS_PATH_WALK loop too if GNU flavor is found.
7326 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7328 * doc/autoconf.texi (Limitations of Make): Update documentation
7329 for `$<'. New entry `Long lines', based on a report from Simon
7330 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7331 paragraph about DJGPP, based on a mail from Richard Dawe.
7333 2004-04-20 Paul Eggert <eggert@twinsun.com>
7335 * tests/c.at (C keywords): Don't assume that GCC supports
7336 "restrict" and "inline", as sufficiently-old GCC versions do not
7337 (also, GCC configured to be in pedantic C89 mode does not).
7338 Problem reported by Sumit Pandya in:
7339 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7341 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7342 consider -g to work if it generates warnings when plain compiles
7343 don't. Problem reported by Braden McDaniel in:
7344 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7346 * doc/autoconf.texi (Slashes): New section, to document a problem
7347 reported by Jim Meyering in:
7348 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7350 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7351 linker output files before linking, to work around IRIX 6 linker bug.
7352 Problem reported by Rainer Orth in:
7353 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7355 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7357 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7358 best tool so far counter rely on the tool path variable name to
7359 avoid checks for one tool being affected by the results of running
7360 the length check on a previous tool.
7362 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7363 match expression argument, as different greps have different
7364 regular expression flavours.
7365 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7366 literals.
7367 (AC_PROG_EGREP): Pass 'EGREP$'.
7368 (AC_PROG_GREP): Pass 'GREP$'.
7370 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7372 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7373 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7375 2004-03-29 Paul Eggert <eggert@twinsun.com>
7377 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7378 Types, Specific Compiler Characteristics, System Services,
7379 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7380 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7381 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7382 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7383 Likewise.
7384 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7385 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,

7387 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7388 Likewise.

7391 pacify libtool 1.5.2. Fix quoting problems in sed command.
7393 2004-03-28 Paul Eggert <eggert@twinsun.com>
7395 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7396 now defines HAVE_DECL_TZNAME if it is declared, when
7397 HAVE_STRUCT_TM_TM_ZONE is not defined.
7398 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7399 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7400 for HAVE_TZNAME.
7402 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7404 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7405 superfluous backslashing of quotes (") in sed expressions;
7406 thanks to Paul Eggert.
7408 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7410 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7411 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7412 H. F. Beebe for the bug report.
7414 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7416 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7417 quoted -cmdline argument in Portland Group compiler (bug
7418 reported by Jeffrey J. Barteet).
7420 2004-03-25 Kevin Ryde <user42@zip.com.au>
7422 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7423 (Run Time): ... here, where it's now mentioned.
7425 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7427 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7428 inherits from language Autoconf-without-aclocal-m4.
7429 (Customizing autom4te): Adjust example; the cache must now be
7430 disabled for language Autoconf-without-aclocal-m4.
7432 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7433 Nathanael Nerode <neroden@twcny.rr.com>

7441 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7442 AC_CHECK_TARGET_TOOLS, and warn for future changes
7443 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7444 AC_CHECK_TOOLS.
7445 (Specifying Names): Document the reason for these future
7446 behavioral changes.
7447 * tests/mktests.sh: Do not generate tests for the
7448 new macros.
7449 * NEWS: Document these changes.
7451 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7452 they make TeX hang up.
7454 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7456 * NEWS: New macro AC_CHECK_ALIGNOF.
7457 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7458 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7459 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7460 vowel.
7461 (AC_CHECK_ALIGNOF): New macro.
7462 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7463 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7464 those for sizeof.
7466 2004-03-03 Paul Eggert <eggert@twinsun.com>
7468 * bin/Makefile.am (edit): Don't use $< in a context where
7469 POSIX doesn't require support for it. Use $@.in instead.
7470 Problem reported by Anthony N. Frasso in
7471 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7472 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7474 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7476 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7477 from the next generation of Libtool.
7478 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7480 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7482 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7483 is not always thread-safe. Report from Nathanael Nerode.
7485 2004-02-18 Paul Eggert <eggert@twinsun.com>
7487 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7488 problem on QNX reported by Stephen Rasku in
7489 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7491 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7492 $(m4sh_m4f_dependencies); this removes a FIXME.
7493 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7494 (MAINTAINERCLEANFILES): Split into pieces,
7495 one per related section. Add $(srcdir)/wrapper.in.
7497 2004-02-09 Paul Eggert <eggert@twinsun.com>
7499 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7500 AC_SUBST provides no portable way to escape literal newlines.
7502 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7503 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7504 Darwin uses -lcrt2.o and there's little point to cataloging all
7505 the system variants. Partial fix reported by Andreas Waechter in:
7506 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7507 for bug reported by Nelson H. F. Beebe in:

7510 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
7512 * doc/autoconf.texi (AU_DEFUN): Fix English,
7513 suggested by Paul Eggert.
7514 * lib/autoconf/autoupdate.m4: Correct reference to
7515 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7517 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7519 * bin/autoupdate.in: Define __file__ so that warnings
7520 refer to the correct file.
7521 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7522 the behavior of the third argument.
7523 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7524 correctly the behavior of the third argument. Document
7525 what the three macros that AU_DEFUN defines do. Fix
7526 warning message when the third argument includes $0
7527 (reported by Alexandre Duret-Lutz).
7529 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7530 Eric Sunshine <sunshine@sunshineco.com>
7531 Paul Eggert <eggert@twinsun.com>
7533 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7534 (AS_INIT): Output shell initialization there. Removed optional
7535 parameter. Expand _AS_SHELL_FN_SPY.
7536 (AS_INIT_WITH_SHELL_FN): Removed.
7537 (_AS_SHELL_FN_SPY): New macro.
7538 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7539 macros.
7540 (AS_SHELL_SANITIZE): Remove loop to find better shell
7541 and documentation for the parameter.
7542 (_AS_DETECT_BETTER_SHELL): Move it here.
7543 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7544 (_AS_RUN): Move it here, support testing with eval.
7545 (AS_REQUIRE_SHELL_FN): Require shell functions when
7546 it is used.
7547 (_AS_LINENO_WORKS): Put around braces, we do not
7548 trigger the bash bug anymore.
7549 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7550 use AS_INIT_WITH_SHELL_FN.
7551 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7553 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7555 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
7556 * doc/autoconf.texi: Don't say that the third parameter
7557 is broken.
7558 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
7559 (AU_DEFUN): Honor the third parameter, create autoupdate
7560 macros with AU_DEFINE.
7561 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7562 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

7569 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
7570 * lib/autoconf/status.m4: Remove FIXME.
7571 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
7572 that the macro is not present anymore in the updated
7573 configure.ac.
7574 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
7575 of autoupdate.
7577 2004-01-28 Paul Eggert <eggert@twinsun.com>
7579 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
7580 copyright years.
7581 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7582 2003 (except 1997) to the list of copyright years. This undoes
7583 the 2003-05-22 change, which removed the older years from the list.
7584 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7586 2004-01-27 Gary V. Vaughan <gary@gnu.org>
7587 Albert Chin-A-Young <china@thewrittenword.com>

7590 grep or ggrep program in PATH that accepts as long lines as
7591 possible.
7592 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7593 AC_PROG_GREP.
7594 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7595 egrep and fgrep respectively if $GREP -E/-F don't work.
7596 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7597 _AC_PROG_GREP, and AC_PROG_SED.
7598 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7599 longest input length accepted by a command.
7600 (AC_PROG_SED): Use it.
7601 * doc/autoconf.texi (Particular Programs): Document the changes.
7602 * NEWS: Updated.
7604 2004-01-27 Paul Eggert <eggert@twinsun.com>
7606 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

7608 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7609 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7611 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7612 bin/autoconf.in, config/Makefile.in, config/config.guess,
7613 config/config.sub, config/install-sh, config/mdate-sh,

7626 sources.
7628 2004-01-26 Paul Eggert <eggert@twinsun.com>
7630 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7631 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7632 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7633 not <inttypes.h>. Problem reported by Tim Mooney in
7634 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7635 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7636 Likewise.
7638 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7639 otherwise "make check" fails because it forbids cmp (I guess
7640 because cmp treats files as binary on DOS-like systems).
7642 * tests/mktests.sh: Update copyright date to 2004, since some tests
7643 have changed in 2004.
7645 2004-01-23 Gary V. Vaughan <gary@gnu.org>
7647 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
7648 non-truncating sed or gsed program in PATH.
7649 * tests/acprograms.at: Add it.
7650 * doc/autoconf.texi (Particular Programs): Document it.
7651 * NEWS: Updated.
7653 2004-01-15 Paul Eggert <eggert@twinsun.com>
7655 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7656 -std1 disables some useful extensions on Tru64. Problem reported
7657 by N. Lichtmaier in
7658 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7660 2004-01-14 Paul Eggert <eggert@twinsun.com>
7662 * doc/autoconf.texi (Programming in M4sh): Document that
7663 AS_MKDIR_P succeeds if the destination is a symbolic link
7664 to an existing directory.
7665 (Limitations of Usual Tools): Note that mkdir -p might not
7666 succeed on symlinks to directories.
7668 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7670 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7671 * bin/autoheader.in: Grammar fix in message.
7672 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7673 Test for dir before calling mkdir -p. (trivial changes)
7675 2004-01-13 Eric Blake <ebb9@byu.net>
7677 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7678 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7680 2004-01-10 Jim Meyering <jim@meyering.net>
7682 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7684 2004-01-09 Paul Eggert <eggert@twinsun.com>
7686 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7687 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7688 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7689 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7690 AC_COMPILE_IFELSE, since we now assume our caller invokes
7691 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7692 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7693 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7694 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7696 2004-01-07 Paul Eggert <eggert@twinsun.com>
7698 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7699 `"'...'"`, as it's confusing (and I suspect it may not work on
7700 some platforms). The code was incorrect anyway, as it assumed
7701 that \$ evaluated to itself in that context. Reported by
7702 Alexandre Duret-Lutz.
7704 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7706 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7707 and _LT_AC_TAGCONFIG.
7709 2004-01-06 Paul Eggert <eggert@twinsun.com>
7711 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7712 example, and add more examples. Reported by Eric Sunshine.
7714 2004-01-05 Paul Eggert <eggert@twinsun.com>
7716 * doc/autoconf.texi (Limitations of Usual Tools):

8207 AT_help_all.
8208 Instead of making AT_help a sequence of assignments to grow
8209 $at_help_all, just make AT_help_all be the growing contents of
8210 $at_help_all, and make a single assignment in...
8211 (AT_INIT): here.
8212 (at_times_skip): Flip the meaning and rename as...
8213 (at_times_p): this.
8214 (AT_INIT): When summarizing the test that ran, remove
8215 $at_times_file after use, and check it is present before trying to
8216 use it.
8218 2003-09-25 Akim Demaille <akim@epita.fr>
8220 Version 2.57d.
8222 * bin/Makefile.am (edit): Handle '@configure_input@'.
8223 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8224 (ifnames): chmod -w.
8225 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8226 executables, not bin/ executables! Otherwise all the magic needed
8227 to find non installed files is turned off. This caused a failure
8228 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8229 as found in its environment (sent by tests/autoreconf): pointing
8230 to bin/autom4te that could not find its files.
8231 * tests/mktests.sh: Force the replacement of generated files, for
8232 the sake of "mv" program that are interactive when overwriting a
8233 -w file.
8234 * config/install-sh: Upgrade from CVS Automake.
8236 2003-09-23 Paul Eggert <eggert@twinsun.com>

8239 versus test -L issues.
8241 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8242 Paul Eggert <eggert@twinsun.com>
8244 Trivial change to support GCC's configuration procedure.
8245 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8246 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8247 about inconsistency if the preprocessor is set to give errors for
8248 any warning.
8249 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8251 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

8264 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
8265 from masters.
8267 2003-09-12 Akim Demaille <akim@epita.fr>
8269 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
8270 not asm/types.h.
8272 2003-09-11 Akim Demaille <akim@epita.fr>
8274 * doc/autoconf.texi (Header Portability): linux/random.h.
8275 From Peter Hendrickson.
8277 2003-09-10 Akim Demaille <akim@epita.fr>
8279 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8280 willing to edit the output files.
8282 2003-09-10 Akim Demaille <akim@epita.fr>
8284 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8285 and AC_FC_FREEFORM.
8286 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8287 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8289 2003-09-09 Akim Demaille <akim@epita.fr>
8291 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
8292 Reported by Gary Vaughan.
8293 * bin/autom4te.in (handle_m4): Likewise.
8295 2003-09-09 Akim Demaille <akim@epita.fr>

8298 trailing files.
8300 2003-09-07 Paul Eggert <eggert@twinsun.com>
8302 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8303 Improve the accuracy of the wording about obsolescence.
8304 From a suggestion by Ian Lance Taylor in
8305 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8307 2003-09-05 Paul Eggert <eggert@twinsun.com>
8309 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8310 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8312 2003-09-04 Akim Demaille <akim@epita.fr>
8314 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8315 AC_FUNC_WAIT3.
8317 2003-09-04 Akim Demaille <akim@epita.fr>
8319 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8320 (freeze): When exiting, use $exit_code.
8321 * lib/autoconf/fortran.m4: Comment changes.
8323 2003-09-04 Akim Demaille <akim@epita.fr>

8327 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8329 Add support for newer Fortran dialects. The F77 interface is
8330 unchanged, and continues to support Fortran 77. New FC macros
8331 correspond to all the old F77 macros, with output variables FC,
8332 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8333 available dialect, but older dialects can be specified. There are
8334 new macros AC_FC_SRCEXT to set the source extension, and
8335 AC_FC_FREEFORM to accept free-form source files.
8337 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8338 New macros.
8339 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8340 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

8342 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

8354 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8355 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8356 Rewrite in terms of the above.
8357 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8358 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
8359 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
8360 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8362 2003-09-02 Paul Eggert <eggert@twinsun.com>
8364 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8365 Document problems with timestamp resolution that 'make', 'cp -p', and
8366 'touch -r' have.
8368 2003-08-27 Akim Demaille <akim@epita.fr>
8370 * tests/m4sugar.at (cross_warning): Make sure to enable the
8371 output, so that we can track spurious m4sugar output.
8372 * tests/local.at: Require 2.57.
8373 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8374 are defaulted by AT_CHECK anyway.
8375 Use AT_CHECK_AUTOM4TE.
8376 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8377 missing dnl.
8379 2003-08-27 Akim Demaille <akim@epita.fr>
8381 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8382 when -Wobsolete is set.
8383 Set it on by default.
8384 Suggested by Klee Dienes.

8395 after AC_OUTPUT.
8397 2003-08-25 Akim Demaille <akim@epita.fr>
8399 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
8400 CVS Bison.

8435 * bin/autom4te.in: Adjust to output the call stack.
8436 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8438 2003-08-22 Akim Demaille <akim@epita.fr>
8440 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8441 * bin/autom4te.in: Adjust.
8443 2003-08-21 Akim Demaille <akim@epita.fr>
8445 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8446 (&verbose): Remove.
8447 (&getopt): Adjust the note and verb channels, depending upon
8448 --verbose.
8449 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8450 * bin/autoupdate.in: Adjust.
8451 Use &verb, not &verbose.
8453 2003-08-21 Akim Demaille <akim@epita.fr>
8455 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8456 &parse_WARNINGS.
8457 ($help): Use Autom4te::ChannelDefs::usage.
8458 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8459 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8461 2003-08-21 Akim Demaille <akim@epita.fr>
8463 First stab at preserving warnings between calls to autom4te,
8464 including when the cache is used.
8466 There are still several issues: (i) there are too many runs of m4
8467 (one for include, one for warnings, and some more), (ii) warnings
8468 spreading on several lines are not handled gracefully, (iii) the
8469 code meant to have the call stack display for errors does not work
8470 (its handling should move from m4 to autom4te).
8472 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8473 Use them.
8474 (@preselect): Add m4_warn.
8475 ($exit_status): Remove, use $exit_code.
8476 ($help): Use Autom4te::ChannelDefs::usage.
8477 (&handle_m4): No longer define the m4_warnings.
8478 At each run, extract and report the warnings.
8479 Always cache the result, including if the exit status is on
8480 failure, since if nothing changes, we should result in the same
8481 failure, hence we can use the cache.
8482 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8483 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8484 Remove.
8485 (m4_warn): Redefine as a do-nothing: it is its invocation that
8486 matters, as warnings are now reported via traces.
8487 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8488 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8489 the latter reveals calls to the former.
8491 Adjust the tests.
8493 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8495 2003-08-21 Akim Demaille <akim@epita.fr>
8497 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8498 Use them.
8500 2003-08-21 Akim Demaille <akim@epita.fr>
8502 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8503 forward order.
8504 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8505 (&parse_warnings): Accept a list of warning requests.
8506 (&usage): Return a string, not a side effect.
8507 (cross): New warning category.
8509 2003-08-21 Akim Demaille <akim@epita.fr>
8511 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8512 (&require_configure_ac): Accept an optional directory argument.
8513 ($configure_ac): Remove.
8514 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8515 (&catfile): Remove.
8516 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8517 * bin/autoscan.in: Adjust.
8519 2003-08-20 Akim Demaille <akim@epita.fr>
8521 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8522 Reported by Alexandre Duret-Lutz.
8524 2003-08-20 Akim Demaille <akim@epita.fr>
8526 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8527 * bin/autom4te: Adjust.
8528 In particular, be Autoconf tools are really silent when properly
8529 working, bind the verbosity of the 'note' channel to $verbose.
8530 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8531 (&xsystem, &contents): Remove, since they are exported by...
8532 * lib/Autom4te/FileUtils.pm: this.
8533 More perldoc.
8534 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8535 * lib/Autom4te/FileUtils.pm: here.
8537 2003-08-20 Akim Demaille <akim@epita.fr>
8539 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8540 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8541 from CVS Automake.
8543 2003-08-20 Akim Demaille <akim@epita.fr>

8546 (autom4te-update): New.
8547 * Makefile.cfg (update): Bind autom4te-update.
8549 2003-08-19 Derek Price <derek@ximbiot.com>
8551 * lib/autotest/general.m4: Comment various HELP_* diversions.
8552 (PARSE_ARGS_BEGIN): New section for option parsing related

8561 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
8563 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8565 * lib/autom4te.in (Automake-preselections): Preselect
8566 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
8567 and m4_sinclude.
8569 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8571 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
8572 (Autoconf-without-aclocal-m4): ... this new language.
8573 * doc/autoconf.texi (autom4te Invocation): Mention
8574 Autoconf-without-aclocal-m4.
8576 2003-08-18 Derek Price <derek@ximbiot.com>
8578 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
8579 RUN-IF-PASS optional arguments.

8590 2003-08-14 Derek Price <derek@ximbiot.com>
8592 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8593 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8594 shorter column three. Add DESCRIPTION to log file content.
8596 2003-08-13 Derek Price <derek@ximbiot.com>
8598 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8599 output.
8601 2003-08-12 Derek Price <derek@ximbiot.com>
8603 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8604 (AT_CHECK_NOESCAPE): Move core functionality to...
8605 (_AT_CHECK): ...this new macro.
8607 2003-08-07 Derek Price <derek@ximbiot.com>
8609 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8610 (AT_CHECK_NOESCAPE): ...to this new macro.
8612 2003-07-31 Paul Eggert <eggert@twinsun.com>
8614 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8615 in Bash 2.01. Problem reported by Brian Gough in
8616 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8618 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8620 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8621 -lcrt1.o, for OS X. (trivial change)
8623 2003-07-07 Paul Eggert <eggert@twinsun.com>
8625 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8626 inside '#ifndef __cplusplus'. Problem reported by
8627 Bob Friesenhahn.
8629 2003-07-06 Bill Clarke <llib@computer.org>
8631 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8632 'long', not 'int', for benefit of Sun's recent C++ compilers
8633 (trivial change). See:
8634 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8635 (This really should be 'intptr_t', not 'long', but that would
8636 take more work.)
8638 2003-06-25 Akim Demaille <akim@epita.fr>
8640 * lib/Makefile.am (autom4te.cfg): Make it read only.
8641 Depend on Makefile since it contains substitutions.
8642 From Paolo Bonzini.

8644 This change was made on autom4te.cfg which is generated.
8645 Reported by Raja R. Harinath.
8647 2003-06-25 Akim Demaille <akim@epita.fr>
8649 * doc/autoconf.texi (Header Portability): sys/mount.h.
8650 From Gareth McCaughan.
8652 2003-06-23 Akim Demaille <akim@epita.fr>
8654 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8655 not all of them. This fixes 1. the fact that when testing
8656 Autoconf there are many many config.log, 2. the incorrect use of
8657 top_srcdir to find config.log.
8658 Don't mix the detailed output of failed test with the summary of
8659 failures. Rather, append detailed log afterwards.
8661 2003-06-23 Akim Demaille <akim@epita.fr>
8663 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8664 always run: output config.log on $at_group_log.
8666 2003-06-23 Akim Demaille <akim@epita.fr>
8668 * tests/torture.at (#define header templates): Don't use quotes in
8669 C++ comments as it puzzles Emacs' sh font-lock-mode.
8671 2003-06-23 Akim Demaille <akim@epita.fr>
8673 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8674 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8675 * tests/atspecific.m4: Rename as...
8676 * tests/local.at: This.
8677 * tests/suite.at: Move the globals into...
8678 * tests/local.at: here.
8679 * tests/Makefile.am: Adjust.
8680 * doc/autoconf.texi (testsuite Scripts): Adjust.
8682 2003-06-21 Kevin Ryde <user42@zip.com.au>
8684 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8685 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8686 ensuring we add -std1 for full-ANSI.
8688 * doc/autoconf.texi (hdrindex): New macro.

8731 PODify.
8733 2003-05-28 Paul Eggert <eggert@twinsun.com>
8735 * NEWS, doc/autoconf.texi (Particular Functions),
8736 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8737 is the inverse of localtime.
8739 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8741 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8742 (handle_exec_errors): New function. Work around $! being
8743 altered by WEXITSTATUS.

8746 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8748 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8749 Do not call `_exit()', simply modify `$?'.
8750 (xsystem): Reset $! before running system, and check it afterward.
8751 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8752 63 for version mismatches.
8754 2003-05-23 Akim Demaille <akim@epita.fr>
8756 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8757 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8758 the middle of a line).
8759 * lib/m4sugar/m4sugar.m4: Likewise.
8760 Remove useless spaces in comments.
8762 2003-05-23 Akim Demaille <akim@epita.fr>
8764 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8765 exit 63, so that we (or Automake's "missing") can tell the
8766 difference with a plain failure.
8767 * doc/autoconf.texi (Notices): Adjust.
8769 2003-05-23 Akim Demaille <akim@epita.fr>

8775 2003-05-22 Jim Meyering <jim@meyering.net>
8776 Paul Eggert <eggert@twinsun.com>
8778 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8779 Remove `#include <stdlib.h>' from the list; we should never
8780 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8781 resulting namespace pollution would cause other tests to fail.
8782 Configure scripts run with some older versions of g++ and HP's
8783 aCC would fail due to such an #include. Problems reported by
8784 Matthew Mueller in <http://bugs.debian.org/120704> and by
8785 Keith Bostic in
8786 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8787 In the test, use the test declaration before including <stdlib.h>,
8788 as that's closer to how it'll be used.
8790 2003-05-23 Akim Demaille <akim@epita.fr>
8792 * doc/autoconf.texi (Header Portability): ucred.h.
8793 From Ian Redfern.
8795 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8797 Overhaul Autotest's logging: generate separate log files
8798 in testsuite.dir/NNN/testsuite.log, and append them to
8799 testsuite.log instead of re-running the test verbosely.
8801 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8802 file descriptor, write 0 to at_status_file instead of setting
8803 at_status=0, initialize some new variables (at_status_file,
8804 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8805 to rerun the tests, instead append the at_group_log to the
8806 at_suite_log when a test fails.
8807 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8808 with the AS_MESSAGE_LOG_FD redirected to stdout.
8809 (AT_CLEANUP): save the output status in $at_status_file
8810 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8811 its original place.
8812 (AT_CHECK): since tests are run with a redirected stdout,
8813 and used to be re-run in verbose mode, turn some $at_verbose
8814 into echo, and don't redirect the output of testing stdout
8815 and stderr.
8817 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8818 the name of the debugging directory and information about
8819 its contents.
8821 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8823 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8824 parameter.

8936 and truncate.
8938 2003-05-06 Akim Demaille <akim@epita.fr>
8940 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8941 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8942 by aclocal.m4 is changed it might require the importing of another
8943 m4 extension file, i.e., aclocal must be run.
8945 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8946 (&parse_args): Use --force with aclocal if required and supported.
8947 (&autoreconf_current_directory): Use &run_aclocal.

8954 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8955 argument instead of a file name, so that the request file remains
8956 open during the whole autom4te run.
8957 ($icache_file): New.
8958 (&freeze): Lock the $icache_file.
8960 2003-04-29 Derek Price <derek@ximbiot.com>
8962 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8963 seperator with m4_append_uniq(). It doesn't work.
8964 (AT_CLEANUP): Add `;' to end of at_help_all.
8965 (AT_INIT): Allow --keywords to be specified more than once. When
8966 grepping $at_help_all for keywords, use the field and keyword
8967 seperators to ensure a complete keyword match. Alter at_prev handling
8968 to support the new --keywords behavior.
8970 2003-04-27 Karl Berry <karl@freefriends.org>
8972 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8973 align better with others. I also made some of the individual
8974 entries on one line, for brevity and to make it easier for me to
8975 sort my dir-example file in the Texinfo distribution :).
8977 2003-04-12 Jim Meyering <jim@meyering.net>

9029 that starts a GUI.
9030 From Ilya Zakharevich.
9032 2003-03-29 Akim Demaille <akim@epita.fr>

9042 header causes problems.
9044 2003-03-28 Akim Demaille <akim@epita.fr>
9046 * tests/torture.at (Configuring subdirectories): Require aclocal
9047 1.4, otherwise the test fails, as it does support configure.ac.
9048 This fixes the "test 40 failed" bug reports.
9050 2003-03-28 Akim Demaille <akim@epita.fr>
9052 * doc/autoconf.texi (C Compiler): `#line' portability.

9173 is not portable inside Makefile.
9175 2003-02-20 Akim Demaille <akim@epita.fr>
9177 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9178 compiler says yeah, but preproc says nope, compiler is right.
9179 Conversely, prompt the reader to send a bug report to the
9180 maintainers of the package, not of Autoconf.
9182 2003-02-20 Klee Dienes <kdienes@apple.com>
9184 * bin/autoreconf.in (autoreconf_current_directory): Properly
9185 handle an empty aclocal.m4.
9187 2003-02-20 Akim Demaille <akim@epita.fr>
9189 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
9190 $ac_prefix_program.
9191 From Larry Jones.
9193 2002-12-23 Paul Eggert <eggert@twinsun.com>
9195 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9196 innocuous variant befor including <limits.h> or <assert.h>. This
9197 works around a bug reported by Albert Chin: HP-UX 11i
9198 (and earlier versions) have a <limits.h> that declares
9199 gettimeofday and many other functions.
9201 2002-12-03 Paul Eggert <eggert@twinsun.com>
9203 Version 2.57.
9205 * NEWS, configure.ac: Update version.
9207 * doc/fdl.texi: Upgrade to FDL version 1.2.
9209 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9210 nontrivially in main's body, so that f's external declaration is
9211 not optimized away in AIX. This should fix the bug reported by
9212 Martin Frydl in
9213 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9215 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9216 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9217 defined, to support freestanding compilers. This should fix the
9218 bug reported by Momchil Velkov in
9219 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9221 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9222 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9223 obsolete AC_CHECK_TYPE. The missing empty arg was reported
9224 by Simon Josefsson in
9225 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
9227 * Makefile.maint (www-gnu): New macro.
9228 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9229 the location has moved.
9231 2002-12-02 Martin Frydl <martin@systinet.com>
9233 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9234 \(.*\) match is too long and there is something more to be checked.
9235 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9237 2002-11-15 Akim Demaille <akim@epita.fr>

9243 * config/move-if-change: Indenting changes.
9244 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9245 * configure.ac (AM_INIT_AUTOMAKE): here.
9246 Require 1.7.1.
9248 2002-11-14 Akim Demaille <akim@epita.fr>
9250 Version 2.55.
9252 * config/config.guess, config/config.sub, config/install-sh:
9253 Update from masters.
9255 2002-11-14 Akim Demaille <akim@epita.fr>
9257 * Makefile.maint: Sync with Bison, i.e.:
9258 (po-check): Scan .l and .y files instead of the
9259 .c and the .h files that they generate. This fixes the bug
9260 reported by Tim Van Holder in:
9261 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9262 Look for N_ as well as for _. Try to avoid matching #define for
9263 N_ and _.
9264 From Paul Eggert.
9266 2002-11-14 Akim Demaille <akim@epita.fr>
9268 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9269 From Paul Eggert and Albert Chin-A-Young.
9271 2002-11-14 Akim Demaille <akim@epita.fr>
9273 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9274 From Paul Eggert and Albert Chin-A-Young.
9276 2002-11-14 Kevin Ryde <user42@zip.com.au>
9278 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9279 than assigning in main, to avoid HP cc +O3 optimizing it away.
9281 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9283 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9284 option. Process --recheck after parsing all options. Pass -q
9285 option to configure on --recheck.
9286 (AC_OUTPUT): Pass -q from configure to config.status.
9287 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9288 arguments to record.
9289 * doc/autoconf.texi (config.status Invocation): Document
9290 config.status -q option.
9292 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9294 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9295 Makefile.in if Makefile.am exists.
9296 (output): Strip `.am' from Makefiles. Don't
9297 output AC_CONFIG_FILES if no Makefiles were found.
9299 2002-11-07 Akim Demaille <akim@epita.fr>
9301 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

9308 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9309 declaration in extern "C" too.
9310 Reported by Roberto Bagnara.
9312 2002-11-06 Akim Demaille <akim@epita.fr>
9314 * tests/torture.at (Configuring subdirectories): Don't use grep
9315 -w.
9316 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9317 Reported by Ezra Peisach.
9319 2002-11-05 Akim Demaille <akim@epita.fr>
9321 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9322 Remove.
9323 We _have_ to stop using the old compatibility scheme that tried to
9324 avoid useless backslashes because Libtool 1.4.3 contains a
9325 AC_DEFINE([error_t], [int],
9326 [Define to a type to use for \`error_t' if it is not
9327 otherwise available.])
9328 We _have_ to quote the single quote and backslashes with \. The
9329 old compatibility scheme saw that ` was backslashed, and therefore
9330 did not quote the single quote. Hence before this patch, Autoconf
9331 was not compatible with Libtool.
9333 2002-11-04 Paul Eggert <eggert@twinsun.com>
9335 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
9336 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
9337 LC_NAME, LC_PAPER, LC_TELEPHONE.

9340 2002-11-04 Akim Demaille <akim@epita.fr>
9342 Version 2.54c.
9344 * Makefile.maint (update, cvs-update, po-update, do-po-update):

9346 * config/texinfo.tex: Update.
9348 2002-11-03 Akim Demaille <akim@epita.fr>
9350 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9351 from...
9352 (&autoreconf): here.
9353 ($help, $make, &parse_args, &autoreconf_current_directory):
9354 Support -m/--make.
9355 * doc/autoconf.texi (autoreconf Invocation): Adjust.

9371 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9373 2002-10-31 Akim Demaille <akim@epita.fr>
9375 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9376 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9377 Make variable, not a shell variable.
9378 Suggested by Bruno Haible.
9380 2002-10-31 Akim Demaille <akim@epita.fr>
9382 * bin/autom4te.in (load_configuration): Reject #args out of any
9383 language.
9385 2002-10-31 Akim Demaille <akim@epita.fr>

9399 Suggested by Tim van Holder.
9401 2002-10-29 Paul Eggert <eggert@twinsun.com>
9403 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
9404 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
9405 Problem reported by Bruno Haible.
9407 2002-10-29 Akim Demaille <akim@epita.fr>
9409 * doc/autoconf.texi (Header Templates): Put also in words what the
9410 pictures says to assist free style readers.
9411 (Customizing autom4te): s/--cache=/--cache /.
9413 2002-10-29 Akim Demaille <akim@epita.fr>
9415 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
9416 sys/wait.h.

9674 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
9675 characters is a syntax warning now.
9676 (_AS_QUOTE): Accept $2 as list of characters to quote.
9677 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
9678 Quote for Perl, not sh.
9679 * bin/autoheader.in: When $debug, report the file which is
9680 `do'ne.
9681 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
9682 `@', to tickle Perl's lists.
9683 Reported by Carlos Velasco.
9685 2002-10-18 Akim Demaille <akim@epita.fr>
9687 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
9688 missing included files _are_ errors.
9689 Thanks to Alexandre Duret-Lutz.
9690 * tests/tools.at (autom4te cache): Adjust.
9691 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

9693 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9694 Adjust.
9695 * tests/tools.at (autom4te): Now it does exit 1.
9697 2002-10-17 Akim Demaille <akim@epita.fr>
9699 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
9700 Fixes the `AC_ARG_VAR' test failures.
9701 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
9702 * lib/freeze.mk (check-forbidden-patterns): New.
9703 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
9704 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
9705 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
9706 /dev/null.
9707 Reported months ago by H. Merijn Brand.
9709 2002-10-17 Akim Demaille <akim@epita.fr>

9716 (ansi2knr.c-url_prefix): Remove.
9718 2002-10-16 Akim Demaille <akim@epita.fr>
9720 Because of caching, some files that no longer exist and are no
9721 longer required can still cause errors.
9722 Reported by Alexandre Duret-Lutz.
9724 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9725 to frozen files in @ARGV, as @ARGV must remain being a list of
9726 files. Rather, at M4 call sites, use this...
9727 (&files_to_options): New function.
9728 (&freeze): Use &error.
9729 (&up_to_date): If a file that was included according to the cache
9730 is no longer there, then the output is out dated.
9731 (&main): Don't even check whether a file is up to date is anyway
9732 --force is given.
9733 * tests/tools.at (autom4te cache): New.
9735 2002-10-16 Akim Demaille <akim@epita.fr>
9737 * bin/autoconf.as: Kill dead options.
9738 * bin/autoupdate.in (&parse_args): Kill old options.
9739 * bin/autoreconf.in (&parse_args): Remove dead options.
9740 Factor some code.
9741 (&autoreconf): Report the directories we enter *and leave*, so
9742 that error messages can be easily located, and use GNU Make
9743 format, so that Emacs' compile mode understands us.
9744 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9745 if some file was changed instead of `print'.
9746 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
9747 (&parse_args): Remove the dead options.
9748 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
9749 autoheader's quiet mode.

9754 2002-10-11 Akim Demaille <akim@epita.fr>
9756 No longer use CPP to check for the existing of headers: use CC to
9757 check for compilability.
9759 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
9760 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
9761 (_AC_CHECK_HEADER_NEW): Rename as...
9762 (AC_CHECK_HEADER): this.
9764 * lib/autotest/general.m4 (AT_INIT): Include the failed test
9765 numbers in the Subject suggestion.
9767 2002-10-11 Akim Demaille <akim@epita.fr>
9769 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.

9775 of `precious'.
9777 2002-10-11 Akim Demaille <akim@epita.fr>
9779 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
9780 file name to enable parallel executions.
9781 From Sam Varshavchik.
9783 2002-10-08 Akim Demaille <akim@epita.fr>
9785 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9786 aclocal invocation, as Gettext macros might not be visible to
9787 aclocal.
9788 Instead of blindly running autopoint, scan configure.ac (not the
9789 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9790 Reported by Paul D. Smith.
9792 2002-10-08 Paul Eggert <eggert@twinsun.com>
9794 Work around problems found when POSIXLY_CORRECT=1 is set.
9795 None of this seems to have anything to do with POSIX, really,
9796 but it's how Perl getopt works.
9797 * bin/autom4te.in (parse_args): Configure GetOpt with
9798 "permute", too.
9799 * doc/autoconf.texi (Invoking autom4te):
9800 --warning -> --warnings.
9801 * lib/autom4te.in: --warning -> --warnings.
9803 2002-09-28 Akim Demaille <akim@epita.fr>

9813 2002-09-28 Akim Demaille <akim@epita.fr>
9815 * lib/autoscan/autoscan.pre: Move all the remaining rules to...

9820 2002-09-28 Akim Demaille <akim@epita.fr>
9822 * tests/torture.at (Configuring subdirectories): Be robust to
9823 users who use config.site to require for a cache: in this case,
9824 the two last configure runs, using two different sets of
9825 arguments, trigger a legitimate error.
9827 2002-09-28 Akim Demaille <akim@epita.fr>
9829 * tests/m4sh.at (Functions Support, Functions and return Support):
9830 New.

9838 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9840 2002-09-28 Akim Demaille <akim@epita.fr>
9842 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
9843 (tm_zone): Move their rules to...
9844 * lib/autoconf/types.m4: here, using AN_ macros.
9845 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
9846 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9847 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9848 * lib/autoconf/programs.m4: here.
9849 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
9850 (ETAGS_FOR_AUTOCONF): New.
9851 Use it.
9853 2002-09-28 Akim Demaille <akim@epita.fr>

9856 * lib/autoconf/autoconf.m4: Include it.

9858 that were listed in the original autoscan.list.
9859 * lib/autoconf/headers.m4: Similarly with headers.
9860 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9861 (.m4.m4f): Don't pass --prepend-include, since that's done by
9862 tests/autom4te itself.
9863 * lib/autoscan/Makefile.am: Include freeze.mk.
9864 (autoscan.list): New target --this file is no longer a source.
9865 (autoscan.pre): New file.
9867 2002-09-28 Akim Demaille <akim@epita.fr>
9869 * bin/autoscan.in (@kinds): Make them singular.
9870 Adjust all uses.
9871 (&init_tables): When --debug, report the list of rules to ease
9872 tracking changes in autoscan.list.
9873 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9875 2002-09-28 Akim Demaille <akim@epita.fr>
9877 * lib/autoscan/functions, lib/autoscan/headers,
9878 * lib/autoscan/identifiers, lib/autoscan/makevars,
9879 * lib/autoscan/programs: Merge into...
9880 * lib/autoscan/autoscan.list: this.
9881 * bin/autoscan.in (&init_tables): Adjust.
9883 2002-09-28 Akim Demaille <akim@epita.fr>
9885 * lib/autoscan/functions, lib/autoscan/headers,
9886 * lib/autoscan/identifiers, lib/autoscan/makevars,
9887 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
9888 `functions' line is now prefixed with `function:'.
9889 * bin/autoscan.in (&init_tables): Adjust.
9891 2002-09-28 Akim Demaille <akim@epita.fr>
9893 From now on, autoscan files must always map a macro name to a
9894 word: there is no `default' macro for autoscan.
9896 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9897 all.
9898 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9899 explicit.
9901 2002-09-28 Akim Demaille <akim@epita.fr>
9903 * bin/autoscan.in (%c_keywords): Remove.
9904 (&used): Keep only track of the words we might be interested in.
9905 (&output_kind): It is no longer needed to look for non active
9906 checks.

9935 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
9936 Reported by Ralf Corsepius.
9937 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9939 2002-09-26 Akim Demaille <akim@epita.fr>
9941 Single suffix rules and seperated dependencies are not portable.
9943 * doc/autoconf.texi (Installation Directory Variables): Update.
9944 (Limitations of Make): Some about `Single Suffix Rules and
9945 Separated Dependencies'.
9946 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9947 (ifnames, autoscan, autom4te): Un-factor into several rules.
9949 2002-09-25 Paul Eggert <eggert@twinsun.com>
9951 * BUGS (Interoperability bugs): New section. Mention libtool
9952 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
9954 2002-09-24 Paul Eggert <eggert@twinsun.com>
9956 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
9957 make handles suffix-rules differently from GNU make.
9959 * bin/Makefile.am (SUFFIXES, .in): Remove.
9960 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
9961 Move the body of the old .in rule here.
9963 2002-09-16 Akim Demaille <akim@epita.fr>
9965 i960 compilers create `b.out' files by default.
9966 Reported by Ralf Corsepius.
9968 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
9969 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
9971 2002-09-13 Paul Eggert <eggert@twinsun.com>
9973 * doc/autoconf.texi (Particular Headers): Remove obsolete
9974 reference to `struct timezone' in the description of
9975 AC_HEADER_TIME.
9977 2002-09-13 Akim Demaille <akim@epita.fr>
9979 Version 2.54.
9981 * config/config.sub, config/config.guess: Update.
9982 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9983 * Makefile.am: Adjust.
9985 2002-09-13 Akim Demaille <akim@epita.fr>
9987 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9988 reading config.log when the compiler is rejected.
9989 Suggested by Guido Draheim.
9991 2002-09-13 Akim Demaille <akim@epita.fr>
9993 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9994 (chdir_init) might hang when stat'ing mounted directories.
9995 Reported by Vance Shipley.
9997 2002-09-12 Akim Demaille <akim@epita.fr>
9999 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10000 the lists.
10002 2002-09-12 Akim Demaille <akim@epita.fr>
10004 * doc/autoconf.texi (Defining Symbols): Present two different
10005 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10006 difference between 1 argument calls, and 2-3 argument calls.
10008 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10010 * doc/autoconf.texi: Review grammar and punctuation.
10012 2002-09-11 Paul Eggert <eggert@twinsun.com>
10014 * doc/autoconf.texi: Fix minor formatting, spelling, and
10015 grammatical typos.
10016 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10017 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10018 is obsolescent.
10020 2002-09-11 Akim Demaille <akim@epita.fr>
10022 * doc/autoconf.texi (Questions): Rename as...
10023 (FAQ): this.

10029 Suggested by Nishio Futoshi.
10031 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>

10034 plain `@' is wanted.
10036 2002-09-09 Akim Demaille <akim@epita.fr>
10038 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10039 `duplicates', since the algorithm was too naive and could keep
10040 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10041 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10042 Reported by Ralf Corsepius.
10043 * tests/torture.at (Configuring subdirectories): Exercise these
10044 cases.
10046 2002-09-09 Akim Demaille <akim@epita.fr>
10048 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10049 looking for a replacement file.
10050 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10051 directory is relative.
10052 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10053 directory definition.
10054 Reported by Andreas Schwab and Jim Meyering.

10058 * doc/autoconf.texi (Setting Output Variables): Clarify what
10059 precious variables are.
10060 Suggested by Pontus Skoeld.
10062 2002-09-05 Akim Demaille <akim@epita.fr>
10064 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10065 (ifnames, autoscan, autom4te): Since we don't only depend on
10066 configure.ac variables (such as VERSION etc.), but also on prefix
10067 and so forth, depend on Makefile, not configure.ac.
10068 Reported by Alexandre Duret-Lutz.
10069 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10071 2002-09-05 Kevin Ryde <user42@zip.com.au>
10073 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10074 doesn't seem to be confined to ia64, just say "some versions".
10076 2002-09-04 Akim Demaille <akim@epita.fr>
10078 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10079 Automake 1.6c.

10086 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10087 Brinkmann.
10089 2002-09-03 Akim Demaille <akim@epita.fr>
10091 * configure.ac: Bump to 2.53d.
10092 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10093 as of today, on Automake's team suggestion.
10095 2002-09-03 Akim Demaille <akim@epita.fr>
10097 Version 2.53c.
10099 2002-09-02 Akim Demaille <akim@epita.fr>
10101 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10102 SITE_MACRO_DIR.
10103 * configure.ac: Disable SITE_MACRO_DIR.
10105 2002-09-02 Jim Meyering <meyering@lucent.com>
10107 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10108 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10109 Also, tweak grammar: s/make sure to/be sure to/.
10111 2002-09-02 Paul Eggert <eggert@twinsun.com>
10113 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10114 directory names are generally preferable to physical names.
10116 2002-09-02 Akim Demaille <akim@epita.fr>
10118 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10119 Reported by Raja R. Harinath.
10120 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10121 * bin/autoupdate.in: Use error instead of die.
10123 2002-09-01 Paul Eggert <eggert@twinsun.com>
10125 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10126 ordinary shell concatenation rather than echo+tr+sed command that
10127 runs afoul of a long-line-related sed bug in Solaris 8.
10129 * bin/autoheader.in (parse_args): --warning -> --warnings.
10131 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10132 stdout, as traditional "ls" does.
10133 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10134 _AC_COMPILER_EXEEXT_O): Likewise.
10135 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10137 * bin/autoconf.as: Add --prepend-include option. This patch was
10138 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10139 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10141 * bin/autoconf.in, configure: Regenerate.
10143 * doc/autoconf.texi (Special Shell Variables): Mention
10144 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10146 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10147 MAILPATH and set PS1, PS2, PS4 to default values, to work
10148 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10149 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10150 the Autoconf documentation specifies; fall back to "unset" only if
10151 this fails. Use a shell for-loop for this rather than an m4 loop,
10152 to shorten the output script.
10154 2002-08-30 Paul Eggert <eggert@twinsun.com>
10156 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10157 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10158 for the CDPATH problem. Document PWD.
10159 (Limitations of Builtins): Document the problem that "cd $foo" and
10160 "ls $foo" may refer to different directories in shells conforming
10161 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10162 example, since the old example is now out of date.
10164 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10165 FOO" and "ls FOO" talk about different directories; this catches
10166 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10167 spaghetti.
10169 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10170 of rolling our own unset.
10171 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10172 in practice we needn't worry about CDPATH if unset doesn't work.
10174 * Makefile.in, aclocal.m4, bin/Makefile.in,
10175 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10176 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10177 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10178 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10179 tests/Makefile.in: Regenerate with Automake 1.6.3.
10181 * config/config.guess, config/config.sub, config/mkinstalldirs:
10182 Update.
10184 * configure: Regenerate with self.
10186 2002-08-30 Kevin Ryde <user42@zip.com.au>
10188 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10189 default output.
10191 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10193 * bin/autom4te.in (Request::load): Correctly test for "do" read
10194 failure.
10196 2002-08-29 Akim Demaille <akim@epita.fr>
10198 * lib/Autom4te/General.pm (&xqx): New.
10199 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10200 hand, which is not portable.
10201 (&error): New.
10202 * bin/autom4te.in: Use them.
10203 Use &error instead of die.
10204 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10205 Adjust.
10207 2002-08-17 Paul Eggert <eggert@twinsun.com>
10209 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10210 default list of compilers to try, since it was long ago superseded
10211 by the ksh fc builtin. Suggested by Steven G. Johnson.
10213 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10215 * doc/autoconf.texi (Invoking autom4te): End the option table,
10216 fixing a bug introduced by the previous patch.
10217 (Limitations of Make): Add a 'target lookup' subentry in the
10218 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10220 2002-07-29 Mark D. Roth <roth@feep.net>
10222 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10223 options and use $AUTOM4TE_PATH.
10224 * doc/autoconf.texi: Remove documentation of autom4te
10225 --include-envvar and --site-macro-subdir options and document
10226 use of $AUTOM4TE_PATH.
10227 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10228 arguments from each language section.
10230 2002-07-29 Paul Eggert <eggert@twinsun.com>
10232 * doc/install.texi: Include copyright symbol in copyright notice.
10234 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10235 Replace with:
10236 (AM_MAKEINFOFLAGS): New macro.
10237 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10238 * Makefile.am (INSTALL): Use the new macros.
10239 Use -o rather than --output, since "missing" does not grok --output.
10241 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10243 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10244 comments do not always work. Never trust the exit status of
10245 `make -k'.
10247 2002-07-24 Kevin Ryde <user42@zip.com.au>
10249 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10250 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10252 2002-07-23 Paul Eggert <eggert@twinsun.com>
10254 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10255 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10256 apparently treats PATH="nonexistent" as if it contained ".".
10257 Bug reported by Stefan `Sec' Zehl.
10259 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10261 * doc/autoconf.texi (Limitations of Make): Mention the special
10262 handling of the obj/ directory by BSD make.

10278 2002-07-18 Akim Demaille <akim@epita.fr>
10280 Version 2.53b.
10282 2002-07-18 Akim Demaille <akim@epita.fr>
10284 * config/config.guess, config/config.sub: Update.
10286 2002-07-18 Akim Demaille <akim@epita.fr>
10288 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
10289 Automake's parts.

10308 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10309 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the

10314 * lib/Autom4te/General.pm (find_file): Browse the directories in
10315 the order they are given.

10337 * lib/autom4te.in: Use --prepend-include instead of --include.
10338 * tests/wrapsh.in: Use --prepend-include instead of --include.

10374 * doc/autoconf.texi: Use @enddots{} or @dots{} where appropriate.
10376 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
10378 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10379 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
10380 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
10381 so that Emacs setups GNU style for perl-mode and cperl-mode.
10383 2002-06-27 Paul Eggert <eggert@twinsun.com>
10385 * config/install-sh: Quote $src. Prefer || to test's -o option,
10386 as per "Limitations of Builtins".
10387 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
10388 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10390 * tests/mktests.sh: Use grep instead of fgrep, as per
10391 "Limitations of Builtins".
10393 2002-06-15 Paul Eggert <eggert@twinsun.com>
10395 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
10396 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
10397 so that we consistently test the just-built programs.
10398 * tests/wrappl.as: Likewise.
10400 2002-06-12 Paul Eggert <eggert@twinsun.com>
10402 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
10403 name, so that symlinks to 'autoconf' work properly. Bug reported
10404 by Bruno Haible.
10405 * bin/autoheader.in (AUTOM4TE): Likewise.
10406 * bin/autoreconf.in (autoconf, autoheader): Likewise.
10407 * bin/autoscan.in (autom4te): Likewise.
10408 * bin/autoupdate.in (autom4te): Likewise.
10410 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
10411 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
10412 on Solaris 2.5.1.
10414 2002-06-11 Andreas Schwab <schwab@suse.de>
10416 * doc/autoconf.texi: Add more dir entries.
10418 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10420 * bin/autom4te.in ($cache): Don't define using `$me', the name
10421 of the cache should not depend on the name under which autom4te
10422 was installed.
10424 2002-06-07 Akim Demaille <akim@epita.fr>
10426 * tests/tools.at (autoconf: forbidden tokens, basic)
10427 (autoconf: forbidden tokens, exceptions): Adjust to the change of
10428 words in autom4te.in.
10430 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

10435 2002-06-07 Akim Demaille <akim@epita.fr>
10437 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
10438 rename as...
10439 (AC_REPLACE_FNMATCH): this.
10440 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
10441 AC_FUNC_FNMATCH_GNU.
10443 2002-06-07 Akim Demaille <akim@epita.fr>
10445 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
10446 Rosetta Stone for Unix.
10448 2002-06-07 Akim Demaille <akim@epita.fr>
10450 * bin/autom4te.in (warn_forbidden): When rejecting a token,
10451 suggest m4_pattern_allow.
10452 Suggested by Adam J. Richter.
10454 2002-06-07 Akim Demaille <akim@epita.fr>
10456 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10457 ac_config_libobj_dir.
10458 (AC_CONFIG_LIBOBJ_DIR): New.
10459 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
10460 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
10461 Use ac_config_libobj_dir to find the replacement files.
10462 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
10463 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
10464 (AC_REPLACE_FNMATCH_GNU): these.
10465 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
10466 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
10467 * tests/mktests.sh (ac_exclude_list): Don't check
10468 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
10470 2002-06-06 Paul Eggert <eggert@twinsun.com>
10472 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
10473 if ln doesn't work.
10474 * NEWS: Likewise.
10475 * doc/autoconf.texi (Configuration Links): Likewise.
10476 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
10478 2002-06-05 Paul Eggert <eggert@twinsun.com>
10480 * config/config.guess, config/config.sub, config/texinfo.tex:
10481 Update from masters.
10483 2002-05-29 Paul Eggert <eggert@twinsun.com>
10485 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
10486 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
10487 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

10494 * lib/m4sugar/Makefile.am (check-local): Likewise.
10495 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
10496 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
10498 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
10499 * doc/autoconf.texi (Particular Programs): Document them.

10501 * NEWS: Likewise.
10503 2002-05-27 Paul Eggert <eggert@twinsun.com>
10505 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
10506 * NEWS, doc/autoconf.texi (Particular Types): Document it.
10507 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
10508 instead of AC_MBSTATE_T, which never existed.
10510 2002-05-23 Akim Demaille <akim@epita.fr>
10512 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
10513 version of Autoconf that is discussed.
10515 2002-05-22 Paul Eggert <eggert@twinsun.com>
10517 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10518 from the default list of compilers to try. Suggested by
10519 Kate Hedstrom.
10520 * NEWS: Document the above.
10521 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10523 2002-05-17 Paul Eggert <eggert@twinsun.com>
10525 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10526 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10527 This improves on an earlier suggestion by H. Peter Anvin.
10529 2002-05-16 Paul Eggert <eggert@twinsun.com>
10531 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10532 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10533 Both macros now accept an optional source-dir arg.
10534 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10536 * NEWS: Document this.
10537 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10539 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10540 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10541 not for GNU extensions; this undoes part of the 2000-11-03 change,
10542 reverting to 2.13-compatible behavior.
10543 Add new optional argument DIR.
10544 (AC_FUNC_FNMATCH_GNU): New macro.
10546 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10548 2002-05-08 Paul Eggert <eggert@twinsun.com>
10550 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10551 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10552 and it causes a 'test' syntax error if it fails.
10553 Bug reported by Stephen Gildea.
10555 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10556 If prototypes are supported, use them to check this at compile-time,
10557 instead of trying to check it at run-time. If we must do a run-time
10558 check, assume that setvbuf is standard when cross-compiling, as
10559 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10560 Bug reported by Paul D. Smith.
10562 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10563 argument specifying location of getloadavg.c. This removes a
10564 FIXME. This idea was taken from Jim Meyering's implementation in
10565 textutils.
10566 * doc/autoconf.texi (Particular Functions): Document this.
10567 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10568 that's what the code does; this fixes a bug reported by
10569 Paul D. Smith.
10571 2002-05-03 Akim Demaille <akim@epita.fr>
10573 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10574 autopoint instead of gettextize.
10575 ($uses_alocal): Rename as...
10576 ($uses_aclocal): this.
10577 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10578 Suggested by Bruno Haible.
10580 2002-05-03 Akim Demaille <akim@epita.fr>
10582 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10584 2002-04-29 Paul Eggert <eggert@twinsun.com>
10586 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10587 files to be 1 second older; just set them to be the same time.
10588 Also, sleep 1 second after the first aclocal, to work around
10589 problems with sub-second time stamps on the input files.
10591 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10593 * doc/autoconf.texi: Mention "set -e -x" lossage
10594 under node "Limitations of Builtins".
10596 2002-04-29 Akim Demaille <akim@epita.fr>
10598 * doc/install.texi: Better wording for setting variables when
10599 running configure.
10600 From Christian Cornelssen.
10602 2002-04-29 Akim Demaille <akim@epita.fr>
10604 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10605 of lack of $LINENO support, then the test will compare the $LINENO
10606 in testsuite vs. the lineno in the test file. This is wrong, of
10607 course.
10608 Be sure to protect it.
10609 Reported by Patrick Welche.
10611 2002-04-25 Akim Demaille <akim@epita.fr>
10613 * doc/autoconf.texi (Obsolete Macros): Typo.

10618 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10619 than some of the input files, hence, on the second run of aclocal,
10620 if some of its input are younger, make them older.
10621 Suggested by Paul Eggert.
10623 2002-04-25 Akim Demaille <akim@epita.fr>
10625 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10626 Thanks to Paul Eggert.
10628 2002-04-25 Akim Demaille <akim@epita.fr>
10630 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10631 and ac_subst_vars be sh variables containing the list of
10632 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10633 DEFAULT diversion.
10634 (_AC_INIT_PREPARE): Use them to log them.
10635 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10636 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10637 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10638 _AC_SUBST_FILES and _AC_SUBST_VARS.
10639 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10641 2002-04-24 Akim Demaille <akim@epita.fr>
10643 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10644 autoheader, so that automake does not complain about a missing
10645 config.h.in that was to be created.
10647 2002-04-23 Akim Demaille <akim@epita.fr>
10649 * bin/autoheader.in (parse_args): --warning takes an argument.

10671 2002-04-22 Akim Demaille <akim@epita.fr>
10673 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

10699 Minor spelling and grammar fixes.
10701 * doc/autoconf.texi: Follow the outline suggested in the GNU
10702 Sample Texts sections of the Texinfo 4.2 manual. Most
10703 importantly, this makes sure that the copyright notices appear in
10704 all output formats. You probably need Texinfo 4.2 to generate
10705 the manual now.
10707 Fix some bugs when using "$@" when there might be zero positional
10708 arguments in cases where this matters.
10710 * bin/autoconf.as: Rewrite so that the problem does not come up.

10726 * tests/atgeneral.m4 (AT_INIT): Likewise.
10728 * tests/c.at: We can't have zero arguments, so remove workaround
10729 that is not portable to Zsh.
10731 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
10733 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

10742 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
10743 workaround for ${1+"$@"}.
10744 * doc/autoconf.texi (Shell Substitutions): Explain it.
10745 From Oliver Kiddle and Peter Stephenson.
10747 Have M4sh perform minimal shell sanitizing.
10749 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
10750 part into...
10751 (_AS_PREPARE): this new macro.
10752 (AS_PREPARE): New.
10753 (AS_INIT): Invoke AS_SHELL_SANITIZE.
10754 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10756 Adjust Autoconf and Autotest.
10758 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10759 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10760 * lib/autotest/general.m4 (AT_INIT): Likewise.
10761 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10762 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10763 AS_SHELL_SANITIZE.
10765 Use this M4sh to generate Autoconf's shell scripts.
10767 * tests/wrapsh.as: New, precursor of wrapsh.in.
10768 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10769 on Autotest and M4sh.
10770 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
10771 (wrapsh.in): New target.
10772 * bin/autoconf.as: New, precursor of autoconf.in.
10773 (autoconf.in): New target.
10775 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

10778 with indented comments in rules.
10780 2002-04-09 Andreas Schwab <schwab@suse.de>
10782 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
10783 ac_top_builddir when setting ac_abs_top_builddir.
10785 2002-04-06 Kevin Ryde <user42@zip.com.au>
10787 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
10788 (Portable Shell): Cross reference to Systemology.
10790 2002-04-05 Akim Demaille <akim@epita.fr>
10792 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
10793 directories when descending in a SUBDIRS.
10794 Reported by Ezra Peisach.
10796 2002-04-04 Andreas Schwab <schwab@suse.de>
10798 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
10799 contains no literal separators.
10801 2002-04-03 Akim Demaille <akim@epita.fr>
10803 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10804 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10805 Use dnl, not the KILL diversion.
10806 Extracted from...
10807 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10808 (AC_CONFIG_LINKS): here.
10809 Adjust.
10810 Don't use the KILL diversion, as it kills spurious output, which
10811 results in failures being hidden.
10812 Use m4_defn where appropriate.
10813 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10814 after the second argument.
10815 Use m4_defn.
10816 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10817 syntax, as it is provided by M4sugar.
10818 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10820 2002-04-03 Andreas Schwab <schwab@suse.de>
10822 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10823 expanded if $# <= 2.
10825 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10826 aclocal.
10828 2002-04-03 Akim Demaille <akim@epita.fr>

10831 (_AC_COMPILER_EXEEXT_REJECT): New.
10832 Also recognize *.bb and *.bbg as compilation byproducts.
10833 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10834 (_AC_COMPILER_OBJEXT): Use them.
10835 Fixes Debian #138666.
10837 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10839 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10841 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10842 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10843 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10844 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10845 (AC_C_CONST): Same.
10846 (AC_C_INLINE): Same.
10847 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10848 * doc/autoconf.texi, NEWS: Document.
10849 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10850 AC_C_CROSS.
10852 2002-04-02 Akim Demaille <akim@epita.fr>

10855 _AS_MKDIR_P_PREPARE.
10857 2002-03-28 Kevin Ryde <user42@zip.com.au>
10859 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10860 to avoid versions of HP C which don't allow that.
10862 2002-03-27 Paul Eggert <eggert@twinsun.com>
10864 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10865 (AS_SHELL_SANITIZE): Invoke it.
10866 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
10868 2002-03-26 Akim Demaille <akim@epita.fr>
10870 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10872 2002-03-26 Akim Demaille <akim@epita.fr>
10874 * doc/autoconf.texi (Introduction): The GNATS base moved.
10876 2002-03-25 Paul Eggert <eggert@twinsun.com>
10878 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10879 as POSIX requires, as it doesn't work with Zsh.
10880 * doc/autoconf.texi (Assignments): Document the problem.
10882 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10884 * doc/autoconf.texi (Limitations of Make): Mention more issue
10885 about VPATH, overriding of macros in sub-makes, and handling of
10886 SHELL.
10888 2002-03-21 Paul Eggert <eggert@twinsun.com>
10890 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10891 problem with here-document buffer boundaries.
10893 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10894 when reinvoking the shell, to work around problems with installers
10895 who put strange things like "cd" commands in their environments.
10897 2002-03-19 Akim Demaille <akim@epita.fr>
10899 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
10900 From Aaron Ucko.
10902 2002-03-19 Akim Demaille <akim@epita.fr>
10904 * bin/autoscan.in (scan_file): Specify the location in `&used'
10905 invocations.
10906 From Nicolas Joly.
10908 2002-03-19 Akim Demaille <akim@epita.fr>
10910 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10911 From Nishio Futoshi.
10913 2002-03-19 Akim Demaille <akim@epita.fr>
10915 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
10917 2002-03-18 Paul Eggert <eggert@twinsun.com>
10919 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10920 (Limitations of Usual Tools): Add mkdir section.
10922 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10923 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10924 back on AS_DIRNAME to compute prefixes otherwise; this is
10925 roughly what mkinstalldirs does. That way, we need not have
10926 our own filename disassembler. The old disassembler did not
10927 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10929 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10930 Create at_test_all by a series of assignments,
10931 not by a single assignment of a long string. The latter causes ksh
10932 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10933 presumably because of a buffer overrun.
10935 2002-03-14 Paul Eggert <eggert@twinsun.com>
10937 * lib/autotest/general.m4 (at_times_skip):
10938 Renamed from at_times. Now a boolean.
10939 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10940 says 'times: not found'.
10942 2002-03-14 Akim Demaille <akim@epita.fr>
10944 * bin/autoreconf.in (&study_gettextize): New.
10945 (&autoreconf): Handle newest gettextize.
10946 Rerun aclocal if needed.
10947 Suggested by Andreas Schwab.
10949 2002-03-13 Akim Demaille <akim@epita.fr>
10951 * doc/autoconf.texi (Special Shell Variables): More about IFS.

10955 * doc/autoconf.texi (Header Portability): New.
10956 Add information about stdint.h and inttypes.h from Paul Eggert.
10958 2002-03-13 Akim Demaille <akim@epita.fr>
10960 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
10961 -p'.
10962 From Bob Proulx.
10964 2002-03-12 Akim Demaille <akim@epita.fr>
10966 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10967 m4_require.
10969 2002-03-11 Andreas Schwab <schwab@suse.de>
10971 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
10972 does not do it if --with-lispdir is given.
10974 2002-03-08 Akim Demaille <akim@epita.fr>
10976 Version 2.53.
10978 2002-03-08 Akim Demaille <akim@epita.fr>
10980 * doc/autoconf.texi (Subdirectories): Clarify that the
10981 subdirectory should exist.
10983 2002-03-08 Akim Demaille <akim@epita.fr>
10985 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10987 2002-03-08 Akim Demaille <akim@epita.fr>
10989 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10990 aliases the actual variables, and modifications of the former
10991 affect the latter.
10993 2002-03-08 Akim Demaille <akim@epita.fr>
10995 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10996 because of C-c: have m4 output in tmp files, then mv them.
10998 2002-03-08 Akim Demaille <akim@epita.fr>
11000 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
11001 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
11002 * bin/ifnames.in: Copyright update.

11008 2002-03-05 Akim Demaille <akim@epita.fr>
11010 * doc/autoconf.texi (Specifying Names): Clarification suggested by
11011 Kevin Ryde.
11013 2002-03-05 Akim Demaille <akim@epita.fr>
11015 Version 2.52i.
11017 2002-03-04 Akim Demaille <akim@epita.fr>
11019 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11020 * lib/autoconf/general.m4 (AC_INIT): More informative error
11021 message for LIBOBJ.
11023 2002-03-04 Akim Demaille <akim@epita.fr>
11025 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11026 parallel builds.
11028 2002-03-04 Akim Demaille <akim@epita.fr>
11030 * doc/autoconf.texi (Transforming Names): Equality between target
11031 and host is irrelevant.
11032 (Specifying Names, Canonicalizing): Remove all references to the
11033 backward compatibility hooks. Rather, collect them all into...
11034 (Hosts and Cross-Compilation): this new section.
11035 * doc/install.texi (System Type): Ditto.
11036 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11037 that `--host' implies cross-compilation.
11039 2002-03-04 Akim Demaille <akim@epita.fr>
11041 * doc/autoconf.texi (Evaluation Macros): New.
11042 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11043 useless.
11044 (_m4_foreach): Define the variant with immediate evaluation so
11045 that it contains exactly the items, not an expression which
11046 evaluation is the current item.
11047 (m4_re_string, m4_re_word): Don't over quote them.
11049 2002-03-04 Akim Demaille <akim@epita.fr>
11051 Instead of having stacking `shift's evaluated at the end, let
11052 `foreach' loops immediately evaluate them.
11054 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11055 $*. This is the n-th time I change my mind, but hopefully this is
11056 the last...
11057 (m4_lquote): New.
11058 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11059 efficient.
11060 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11061 it was only a hack for m4_text_wrap.
11062 (m4_car2): Remove, replaced by...
11063 (m4_cdr): New.
11064 (_m4_foreach): Adjust.
11065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11066 m4_bpatsubst for clarification.
11068 2002-03-04 Akim Demaille <akim@epita.fr>
11070 * doc/autoconf.texi (Changequote is Evil): New.

11083 of messages.
11085 2002-02-28 Akim Demaille <akim@epita.fr>
11087 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
11088 message to be sent.
11090 2002-02-28 Kevin Ryde <user42@zip.com.au>

11097 From Akinori Musha.
11099 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
11101 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
11102 translate \r\n to \n.
11104 2002-02-07 Akim Demaille <akim@epita.fr>
11106 Version 2.52h.
11108 2002-02-07 Akim Demaille <akim@epita.fr>

11115 2002-02-07 Akim Demaille <akim@epita.fr>
11117 Fix Autoconf PR/207:
11118 AC_PREFIX_PROGRAM fails with dashed program names
11120 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11121 variable when looking for the prefix program.
11122 Now it also works for shell variables.
11124 2002-02-07 Akim Demaille <akim@epita.fr>
11126 * doc/autoconf.texi (Limitations of Builtins): More about
11127 case/esac.
11129 2002-02-06 Akim Demaille <akim@epita.fr>
11131 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
11132 case/esac, some shells don't support it.
11133 Reported by Zack Weinberg.
11134 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
11136 2002-02-06 Akim Demaille <akim@epita.fr>
11138 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
11139 sure not to introduce newlines in at_groups.
11140 * lib/autotest/Makefile.am (autotest.m4f): Typo.
11142 2002-02-06 Akim Demaille <akim@epita.fr>
11144 * tests/torture.at (Configuring subdirectories): Skip if aclocal
11145 is not available.
11147 2002-02-05 Paul Eggert <eggert@twinsun.com>
11149 * doc/autoconf.texi (Specific Compiler Characteristics):
11150 Describe HP-UX cc bug workaround more accurately.
11151 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
11152 not unsigned long.
11153 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11154 cross-compilers, too. This undoes some of the most recent change
11155 to this file.
11157 2002-02-05 Akim Demaille <akim@epita.fr>
11159 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
11160 to make sure they are up to date when `check' is run.
11162 2002-02-05 Akim Demaille <akim@epita.fr>
11164 * doc/autoconf.texi (Making testsuite Scripts): Document
11165 package.m4.
11167 2002-02-05 Akim Demaille <akim@epita.fr>
11169 * lib/freeze.mk: New.
11171 2002-02-05 Akim Demaille <akim@epita.fr>
11173 Implement `autom4te --freeze'.
11175 * bin/autom4te.in (&freeze): New.
11176 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11177 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11179 2002-02-05 Akim Demaille <akim@epita.fr>
11181 * bin/autom4te.in (&parse_args): Implement `frozen files are
11182 optional are the sum of the previous files on the command line'.
11183 Also, pass `--reload-state=' on them, so...
11184 (handle_m4): don't.
11185 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11186 (M4sh): Rely on M4sugar.
11187 (Autotest, M4sh, M4sugar): Use frozen files.
11189 2002-01-31 Akim Demaille <akim@epita.fr>
11191 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11192 * doc/autoconf.texi (Initializing configure): Adjust.
11194 2002-01-30 Akim Demaille <akim@epita.fr>
11196 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11197 alphanumeric to `-' instead of `_'.
11199 2002-01-30 Akim Demaille <akim@epita.fr>
11201 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11202 for plain code, the other for cross-compilation code. The latter
11203 is now run with GCC only.
11204 * doc/autoconf.texi (Compilers and Preprocessors): New.
11206 2002-01-30 Akim Demaille <akim@epita.fr>
11208 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11209 values.
11210 * doc/autoconf.texi (Initializing configure): Explain how to
11211 change AC_INIT default values.
11213 2002-01-29 Akim Demaille <akim@epita.fr>
11215 * tests/torture.at (Configuring subdirectories): Use configure.in,
11216 so that aclocal 1.4 works.
11217 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11219 2002-01-28 Akim Demaille <akim@epita.fr>
11221 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11222 needs an argument.
11224 2002-01-28 Akim Demaille <akim@epita.fr>
11226 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11227 AUTOTEST_PATH *after* it was set.
11228 Don't put `.' in the PATH: the user should be precise and `./' if
11229 needed. In addition, given that the test suite does some `cd', if
11230 `.' is in the path, the `tested programs' sections will report
11231 programs found in the test suite's directory, while during the
11232 tests (performed in their own directory), these programs are no
11233 longer visible. In other words, the results is confusing and
11234 useless.
11235 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11237 2002-01-24 Akim Demaille <akim@epita.fr>
11239 Version 2.52g.
11241 2002-01-24 Akim Demaille <akim@epita.fr>
11243 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
11244 * doc/autoconf.texi: Finally add Akim as an author.
11246 2002-01-24 Akim Demaille <akim@epita.fr>
11248 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11249 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11250 Bourne. Use /bin/sh.
11251 From Andreas Buening.
11253 2002-01-24 Akim Demaille <akim@epita.fr>
11255 * config/config.guess, config/config.sub, config/texinfo.tex:

11263 * config/missing.m4, config/sanity.m4, config/select.m4,
11264 * config/strip.m4: Remove, to ease sync'ing with any version of
11265 Automake.
11267 2002-01-24 Akim Demaille <akim@epita.fr>
11269 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11270 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
11271 Reported by Geir Ove Myhr.
11273 2002-01-21 Akim Demaille <akim@epita.fr>
11275 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11277 2002-01-21 Akim Demaille <akim@epita.fr>
11279 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11280 message on invalid options.
11281 * bin/autom4te.in (parse_args): Don't use
11282 Autoconf::General::getopt with non valid options.
11284 2002-01-17 Jim Meyering <meyering@lucent.com>
11286 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11287 $ac_cv_exeext so we don't use an old, invalid, cached value.
11289 2002-01-11 Akim Demaille <akim@epita.fr>
11291 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11292 Meyering.

11294 limitation.

11298 2002-01-06 Akim Demaille <akim@epita.fr>
11300 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11301 package.m4, since is really depends upon configure.ac, not
11302 configure.
11303 * doc/autoconf.texi (testsuite Scripts): Adjust.
11304 * tests/Makefile.am (package.m4): New.
11305 EXTRA_DIST it since its a source.
11307 2002-01-06 Akim Demaille <akim@epita.fr>
11309 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11310 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11311 and PACKAGE_BUGREPORT from here...
11312 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11313 arguments.
11314 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11315 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11316 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11317 * tests/tools.at (autoheader): Adjust.
11318 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
11320 2002-01-06 Akim Demaille <akim@epita.fr>

11326 * doc/autoconf.texi (Output): Improved wording regarding use of
11327 AC_OUTPUT.
11328 From Olly Betts.
11330 2001-12-18 Kevin Ryde <user42@zip.com.au>
11332 * doc/autoconf.texi (Function Portability): Add notes on sscanf
11333 sometimes needing writable input.
11335 2001-12-17 Jim Meyering <meyering@lucent.com>
11337 * doc/autoconf.texi (New Macros): Tweak wording.
11339 2001-12-14 Akim Demaille <akim@epita.fr>
11341 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11342 trailing files, don't apply `-rf' to files which might not be
11343 created by configure (core, core.*, and *.core), but just `rm -f'.
11344 Suggested by Jonathan Kamens.
11346 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11348 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11350 2001-12-14 Akim Demaille <akim@epita.fr>
11352 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11354 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11356 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11357 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11358 abs_srcdir, top_srcpath to abs_top_srcdir.
11359 (_AC_OUTPUT_FILES): Adjust.
11360 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11361 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11362 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11364 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11366 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11367 C/Fortran linking on HP/UX, by extracting the Fortran library
11368 search path from the LPATH line in the $F77 -v output.
11370 2001-12-12 Kevin Ryde <user42@zip.com.au>
11372 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11373 forbidden file descriptors table.
11375 2001-11-26 Akim Demaille <akim@epita.fr>
11377 * bin/autoscan.in (%c_keywords): Build it at top level.
11378 Map to 1 in order to simplify its uses.
11380 2001-11-26 Akim Demaille <akim@epita.fr>
11382 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11383 Remove $filepath, useless.
11384 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11385 variables, they are really part of the tokens.
11386 Split the input line on spaces and then look for tokens.
11387 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11388 because of `lex$U.$(OBJEXT)'.
11389 (&scan_files): Use "@list" instead of join.
11390 * doc/Makefile.am (CLEANFILES): Add *.fns.
11392 2001-11-26 Akim Demaille <akim@epita.fr>
11394 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11395 Remove, replaced by...
11396 * tests/wrappl.in: Be common for all the Perl executables.
11397 In particular autoscan and autoheader want -I.
11398 * configure.ac: Adjust.
11399 * lib/autoscan/headers: errno.h is portable.
11401 2001-11-26 Akim Demaille <akim@epita.fr>
11403 * bin/autoscan.in (used): New.
11404 Use it.
11406 2001-11-26 Akim Demaille <akim@epita.fr>
11408 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11409 directives.
11410 (&scan_sh_file): Remove a duplicate pattern.
11411 (&check_configure_ac): Use long options.
11412 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11414 2001-11-26 Akim Demaille <akim@epita.fr>
11416 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11417 Before, having a line containing the opening of a multi line
11418 comment made the whole line be ignored.
11420 2001-11-26 Akim Demaille <akim@epita.fr>
11422 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11423 (testsuite Scripts): Be one of its subsection.
11424 (Autotest Logs): New.
11426 2001-11-26 Akim Demaille <akim@epita.fr>
11428 Test groups are now run two directories deeper.
11430 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11431 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11432 at_top_builddir.
11433 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11434 top_srcdir, builddir and top_builddir.
11435 Use `at_*dir' relatively to the directory containing the
11436 suite, use `*dir' when relatively to the current group dir.
11438 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11440 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11441 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11442 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11443 spelling errors.
11445 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11447 * doc/autoconf.texi (Using System Type): Add an example of `case
11448 $host' usage so people quit using `case $target' everywhere.
11450 2001-11-22 Akim Demaille <akim@epita.fr>
11452 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11453 spotted by Jim Meyering.
11455 2001-11-16 Paul Eggert <eggert@twinsun.com>
11457 This patch implements a `long double' suggestion by Oliver Kiddle.
11459 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11460 static, to catch errors if the value isn't known at compile-time
11461 and the compiler supports dynamic arrays. Change its name from
11462 `_array_' to `test_array' to avoid potential name clashes.
11463 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11464 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11465 better than double. Catch a bug in GCC 2.95.2 x86.
11466 * doc/autoconf.texi (C Compiler): Document the above.
11467 * NEWS: Likewise.
11469 2001-11-13 Akim Demaille <akim@epita.fr>
11471 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11472 hand.
11473 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11475 2001-11-13 Akim Demaille <akim@epita.fr>
11477 * lib/autotest/general.m4 (AT_INIT): After having run the test
11478 group, go back to the initial directory, not to at_suite_dir.
11480 2001-11-13 Akim Demaille <akim@epita.fr>
11482 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11483 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11484 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11485 option.
11486 (AT_CHECK_CONFIGURE): Use absolute paths.
11487 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11488 The problem is still the old one: there is no means in M4 (that I
11489 know about) to create a defining macro, because there is no means
11490 to create `$1' etc., therefore, the defining macro ``swallows''
11491 all the arguments meant to the defined macro.
11493 2001-11-13 Akim Demaille <akim@epita.fr>
11495 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11496 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11497 configure.ac.
11498 * tests/aclocal.m4: Remove, as it is no longer used.
11500 2001-11-13 Akim Demaille <akim@epita.fr>
11502 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11503 variable names when referring to a single test group, or to
11504 `suite' when referring to the whole test suite.
11505 `at_last_test' is removed: m4 compute at_format itself.
11506 (at_stdout, at_stder1, at_stderr): New variables.
11507 (AT_CHECK): Use them.
11509 2001-11-13 Akim Demaille <akim@epita.fr>
11511 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11512 in PATH.
11513 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11514 Do it as soon as a test fails, don't wait till the end of the test
11515 suite.
11516 Don't remove $as_me.[0-9]*, since these files no longer exist.
11518 2001-11-13 Akim Demaille <akim@epita.fr>
11520 * tests/tools.at: Use absolute paths, since we are no longer run
11521 in place.
11523 2001-11-13 Akim Demaille <akim@epita.fr>
11525 Now that tests are running in their own private dir, there is no
11526 need to list the files to remove at the end of tests groups.
11528 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11529 (AT_data_files, at_data_files): Remove.
11530 (AT_CLEANUP, AT_DATA): Simplify.
11531 (AT_INIT): Adjust.
11532 Remove the group dir if !debug && !failed.
11533 * tests/atspecific.m4: Adjust.
11535 2001-11-13 Akim Demaille <akim@epita.fr>
11537 Start a new layout for Autotest: `testsuite' creates
11538 `testsuite.dir' in which the at-check-line etc. files are to be
11539 found, and `testsuite.dir/003' where the test group 3 is run.
11541 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11542 at_check_line_file, at_format, at_test_normalized, at_group_dir
11543 are new variables.
11544 Create the directories.
11545 Use absolute paths for at- files.
11546 (AT_CHECK): Adjust.
11548 2001-11-11 Michael Matz <matz@kde.org>
11550 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11551 (m4_car2): New.
11552 (m4_car): Properly quote arguments.
11554 2001-11-13 Akim Demaille <akim@epita.fr>
11556 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11557 with stricter rules on LIBOBJS.
11559 2001-11-12 Paul Eggert <eggert@twinsun.com>
11561 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11562 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11563 __PROTOTYPES too.
11565 2001-11-12 Akim Demaille <akim@epita.fr>
11567 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11569 2001-11-12 Akim Demaille <akim@epita.fr>
11571 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11572 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11573 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11574 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11575 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11576 specify to what the macro should be defined (typically to 1).
11578 2001-11-12 Akim Demaille <akim@epita.fr>
11580 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11581 From Jim Meyering.
11583 2001-11-12 Akim Demaille <akim@epita.fr>
11585 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11586 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11587 definition used by Automake where LEX is +/- "${missing} lex" and
11588 `missing' itself contains variables.
11590 2001-11-12 Akim Demaille <akim@epita.fr>
11592 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11593 Now that M4sh pushes BODY, the comments were output at the end of
11594 the test suites.
11596 2001-11-08 Akim Demaille <akim@epita.fr>
11598 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11599 that we can trace macros from aclocal.m4.
11600 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11601 obsoleted, and redirect to the former anyway.
11602 Reported by Ralf Corsepius.
11604 2001-11-08 Akim Demaille <akim@epita.fr>
11606 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11607 processed only if present.
11608 * tests/torture.at (Configuring subdirectories): Use autoreconf
11609 instead of successive calls to autoconf.
11610 Add a nonexistent subdirectory to exercise the patch above.
11611 Reported by Ralf Corsepius.
11613 2001-11-08 Kevin Ryde <user42@zip.com.au>
11615 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11616 doesn't accept .S files.

11624 (handle_output): Use it.
11625 Read m4_pattern_forbid with messages.
11627 2001-11-05 Akim Demaille <akim@epita.fr>
11629 * bin/autom4te.in (--normalize): Remove.
11630 * lib/autom4te.in: Adjust.
11632 2001-11-05 Akim Demaille <akim@epita.fr>
11634 * tests/Makefile.am (testsuite): Rename this target as...
11635 ($(TESTSUITE)): this.
11636 From Nicolas Joly.
11638 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11640 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11641 the --prefix option, also remove it's argument.
11643 2001-11-05 Akim Demaille <akim@epita.fr>
11645 * doc/autoconf.texi (testsuite Invocation): Update.
11646 (Writing testsuite.at): Update.

11654 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11655 (&file_name_is_absolute): New, wrappers around routines from
11656 File::Spec.
11657 Use and export them.
11658 (&find_configure_ac): Optionally take a directory where to look at.
11659 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11660 the arguments.
11661 Default @ARGV to `.', not find_configure_ac.
11662 (&autoreconf): Argument is a directory.
11663 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11664 * doc/autoconf.texi (autoreconf Invocation): Update.
11666 2001-11-03 Akim Demaille <akim@epita.fr>
11668 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11669 (@export_forward_subs): New.
11670 Add basename, dirname, and fileparse.
11671 (@EXPORT): Adjust.
11672 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11673 Don't look for aclocal flags if we already know aclocal is not
11674 used.
11675 Move aclocal.m4t only if it exists.
11676 Reported by Ezra Peisach.
11678 2001-11-03 Akim Demaille <akim@epita.fr>
11680 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11681 passed on command line, defaulting to ./configure.ac if present.
11682 (&maybe_autoreconf, File::Find): Remove, unused.
11683 (&autoreconf): If autoconf is not used, don't try to trace.
11685 2001-11-02 Akim Demaille <akim@epita.fr>
11687 * configure.ac: Bump to 2.52g.
11689 2001-11-02 Akim Demaille <akim@epita.fr>
11691 Version 2.52f.
11693 2001-11-02 Akim Demaille <akim@epita.fr>
11695 * config/config.guess, config/config.sub, doc/standards.texi:
11696 * config/lispdir.m4: Update from masters.
11697 * configure.ac: Bump to 2.52f.
11699 2001-11-02 Akim Demaille <akim@epita.fr>
11701 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11702 Don't run aclocal when aclocal.m4 is not from aclocal.
11703 From Ezra Peisach.
11704 Don't run libtoolize and gettextize if --install is not given.
11706 2001-11-01 Paul Eggert <eggert@twinsun.com>
11708 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11709 be invoked before _AS_LINENO_PREPARE.
11710 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11711 than character ranges.
11713 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11714 invoking AS_BASENAME. Set the locale variables to 'C' if
11715 possible, as POSIX requires this to get the traditional
11716 behavior.
11717 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11719 2001-10-31 Paul Eggert <eggert@twinsun.com>
11721 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11722 with {}, as that triggers a bug in Bash 2.05.
11724 (_AS_LINENO_PREPARE): Use Sed rather than
11725 Awk. Fix the sed prepass to work even if there are multiple
11726 instances of $LINENO on the same line. Do not substitute for
11727 other variables like $LINENOT. Do not check file dates; such a
11728 check is unreliable on sufficiently fast machines, and removing
11729 the check makes the code simpler and more reliable. Check for
11730 output and chmod failures.
11732 * doc/autoconf.texi (Special Shell Variables): Document
11733 the above.
11735 2001-10-31 Akim Demaille <akim@epita.fr>
11737 * tests/Makefile.am (atconfig): Remove this target, Automake
11738 handles it now.
11740 2001-10-31 Akim Demaille <akim@epita.fr>
11742 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11743 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11744 provided, while it is optional.
11745 * configure.ac: Adjust.
11747 2001-10-26 Paul Eggert <eggert@twinsun.com>
11749 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11750 lib/Autom4te/Struct.pm:
11751 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11752 with 5.005_02.
11754 * doc/autoconf.texi (Special Shell Variables): Document some
11755 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11757 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11758 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11759 eval $LINENO is not portable in practice.
11761 2001-10-24 Akim Demaille <akim@epita.fr>
11763 * lib/Autom4te/General.pm (backname): New.
11765 2001-10-24 Akim Demaille <akim@epita.fr>
11767 * m4/: Remove, merged into...
11768 * config/: here.
11770 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11772 * doc/autoconf.texi (Shellology): Mention the problems with bash
11773 2.05's use of ANSI quoting in its `set' builtin.
11775 2001-10-22 Paul Eggert <eggert@twinsun.com>
11777 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11778 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11779 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11780 POSIX decided to standardize on the int flavor of strerror_r.
11781 Always do char* test, as there's no reason not to.
11782 Assign to a char* var, to catch strerror_r that returns int*.
11784 * doc/autoconf.texi (Particular Functions):
11785 Document the above changes. Also, document the fact that
11786 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11788 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11790 2001-10-20 Akim Demaille <akim@epita.fr>
11792 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11793 the executable was missing from the log.

11797 * lib/Autom4te/General.pm (&update_file): If destination is
11798 unchanged, remove the source.
11799 (&up_to_date_p): Don't be verbose, be debug.
11800 * bin/autoreconf.in: No longer support --m4dir.
11801 (&autoreconf): Display the full path of the configure.ac we are
11802 studying.
11803 Trace it only once.
11804 Be sure to honor --force with gettextize.
11805 Always run aclocal.
11806 * doc/autoconf.texi: Adjust.
11808 2001-10-20 Akim Demaille <akim@epita.fr>
11810 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11811 Remove, dead.
11812 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11813 `intl' is already present, as it refuses unless --force.
11814 (&parse_args): Use -I, --include instead of the old Autoconf
11815 options.
11816 ($localdir, $autoconf_dir): Remove.
11817 (@include): New.
11818 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11820 2001-10-19 Jens Petersen <petersen@redhat.com>

11829 Don't mention `automatically' in addition to `generated'.
11830 * tests/torture.at (#define header templates): Adjust.
11832 2001-10-19 Akim Demaille <akim@epita.fr>
11834 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11835 comment, explain how to install automatic mode selection.
11836 From Russ Allbery.
11838 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11840 * bin/autoreconf.in (autoreconf): Display the path to the
11841 configure.ac being studied.
11843 2001-10-18 Paul Eggert <eggert@twinsun.com>
11845 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11846 long, to work around a bug in the HP C compiler version HP92453-01
11847 B.11.11.23709.GP.
11849 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11850 (AS_BASENAME_EXPR): New macro.
11851 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11852 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11853 and fall back on 'sed' only if the other two fail. This makes
11854 AS_BASENAME act more like AS_DIRNAME.
11855 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11856 contains white space.
11857 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11858 Use AS_DIRNAME, since I think it's now DOS-friendly.
11859 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11860 Allow "dirname //FOO" to return either / or //, as POSIX allows
11861 either behavior.

11865 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

11867 From Eric Sharkey.

11871 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
11872 m4_define, since...

11966 2001-10-08 Akim Demaille <akim@epita.fr>
11968 Use `add-log-current-defun-function' for ChangeLog creation.

11990 * tests/tools.at (AT_DATA_FORBIDDEN): New.

12001 empty, and if we can find a shell that does support LINENO,
12002 then set CONFIG_SHELL to that shell and then re-execute
12003 ourselves with CONFIG_SHELL.
12005 2001-10-05 Paul Eggert <eggert@twinsun.com>
12007 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
12008 doesn't exist. Remove *.tmp, as a .tmp file is created during the
12009 build of $(TESTSUITE).
12011 2001-10-05 Akim Demaille <akim@epita.fr>
12013 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

12033 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
12034 (AS_SHELL_SANITIZE): here. Use it.
12035 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
12036 From Paul Eggert.
12038 2001-10-04 Akim Demaille <akim@epita.fr>
12040 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
12041 combination of Awk and sed to replace $LINENO.
12043 2001-10-02 Paul Eggert <eggert@twinsun.com>
12045 * doc/autoconf.texi (Limitations of Builtins): You can't use
12046 "source"; it's not portable. Remove confusing and
12047 somewhat-incorrect example involving "." and "/".
12049 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
12050 compatibility with POSIX shells.
12052 2001-10-02 Akim Demaille <akim@epita.fr>
12054 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
12055 instead of exec'ing to preserve $0 and $@.
12057 2001-10-01 Akim Demaille <akim@epita.fr>
12059 * tests/testsuite (AT_INIT) <at_pass_list>: New.

12078 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
12079 Don't use nested parenthesization. This patch was originally
12080 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
12081 but somehow it didn't get incorporated then.
12082 * doc/autoconf.texi (Limitations of Usual Tools):
12083 Clarify remark about sed and nested parenthesization.
12085 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
12086 Report an error if the size cannot be determined even though
12087 the type exists.
12088 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12089 Check for `expr' arithmetic overflow, and for compilation failure,
12090 and invoke a new argument $4 if either is discovered.
12091 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
12092 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
12094 2001-09-28 Akim Demaille <akim@epita.fr>

12102 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
12103 (AT_TESTED): this.

12105 Output `AT_tested' only when existing.
12106 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
12108 2001-09-27 Akim Demaille <akim@epita.fr>
12110 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
12111 generates too many bug reports.
12113 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
12114 status when executing the ACTION-IF-FALSE.

12123 (Broken/missing compilers, AC_PROG_CPP with warnings)
12124 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
12125 (AC_PROG_CPP requires AC_PROG_CC): here and...
12126 * tests/fortran.at (GNU Fortran 77): there.
12127 * doc/autoconf.texi (autoconf Invocation): Fix the example:
12128 AC_TRY_RUN is about compilation, not shell commands.
12129 (Test Programs): AC_TRY_RUN works as used to be advertised.
12131 2001-09-27 Akim Demaille <akim@epita.fr>
12133 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
12134 Raja R Harinath:
12135 Be sure to detect when $LINENO always returns the same value.
12136 Look for the original script, basename($0) is certainly not
12137 enough.
12138 Pass the CLI arguments to `$as_me.lineno'.
12140 2001-09-25 Akim Demaille <akim@epita.fr>
12142 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

12150 of --language now.
12152 2001-09-23 Akim Demaille <akim@epita.fr>
12154 * doc/autoconf.texi (Top): Wrap in @ifnottex.
12156 2001-09-23 Akim Demaille <akim@epita.fr>
12158 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
12159 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
12160 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
12161 builddir, buildpath, top_builddir, and top_buildpath.
12162 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
12163 the current directory.

12168 variables.
12170 * lib/autotest/general.m4: Do not reset AT_victims.
12171 Don't compute at_srcdir nor at_top_srcdir.
12173 * tests/tools.at: Hence use top_srcdir.
12175 * tests/Makefile.am, tests/autoconf, tests/autoheader,
12176 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
12177 Remove.

12179 * tests/wrapsh.in, tests/autoupdate.in: New.
12180 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
12181 * configure.ac: Build the position independent wrappers.
12183 * man/Makefile.am: Now that test wrappers are position
12184 independent, use them and drop dark envvar magic.
12186 2001-09-23 Akim Demaille <akim@epita.fr>
12188 * doc/autoconf.texi (Common Shell Constructs): Rename as...
12189 (Programming in M4sh): this.

12219 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
12221 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

12232 * lib/autoconf/autotest.m4: Create `package.m4'.
12233 * tests/Makefile.am (package.m4): Remove.
12235 2001-09-22 Akim Demaille <akim@epita.fr>
12237 Rely on `$LINENO' when possible instead of `__oline__'.
12239 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
12240 `$LINENO' support replacement when not supported.
12241 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
12242 them explicitly to be sure they are not output before this section
12243 (via m4_require). Cosmetic only.
12244 * lib/autoconf/c.m4, lib/autoconf/general.m4,
12245 * lib/autoconf/programs.m4: Replace all the occurrences of
12246 `__oline__' with `$LINENO'.
12247 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
12249 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
12251 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
12252 character (u: -> ue) in a code comment.
12253 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
12254 it works.
12256 2001-09-21 Akim Demaille <akim@epita.fr>
12258 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
12259 Suggested by Jim Meyering.
12261 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12263 * lib/autoconf/programs.m4: Use extensions listed in
12264 $ac_executable_extensions when looking for programs.
12266 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12268 * lib/autoconf/general.m4: Fix a small Englisho.
12269 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
12270 setting up ac_dir_suffix and ac_top_builddir.
12271 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
12273 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

12276 PATH_SEPARATOR.
12277 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
12278 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
12279 be used instead of ':'.
12280 * lib/autotest/general.m4: Replace occurrences of ':' in
12281 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
12283 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12285 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12286 arguments. Fixed a typo.
12288 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12290 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12291 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12293 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12295 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12296 * bin/autoupdate.in: Ditto.
12297 * bin/autoheader.in: Reworded a few comments.
12298 * bin/autoconf.in: Reworded help text for a few options.
12299 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12300 * bin/autoscan.in, bin/autoupdate.in: Ditto.
12302 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12304 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12305 already have $file). Set output files to binary mode (helps avoid
12306 CR issues on DOSish systems).
12308 2001-09-19 Akim Demaille <akim@epita.fr>
12310 * lib/autotest/general.m4: Englishoes.
12311 From Tim Van Holder and Alexey Mahotkin.
12313 2001-09-18 Paul Eggert <eggert@twinsun.com>
12315 * doc/autoconf.texi (Common Shell Constructs): New node,
12316 documenting AS_DIRNAME.
12317 (Limitations of Usual Tools): Refer to it when discussing dirname.
12318 Also, update discussion of POSIX standard to reflect latest draft.
12320 * lib/autoconf/c.m4:
12321 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12323 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12324 Do not pass a first argument with leading '-'
12325 to expr, by parenthesizing initial integers that might be negative.
12327 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12328 now merely checks whether it is an error to pass an argument
12329 to getpgrp.
12331 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12332 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12333 whether it is a (compile-time) error to pass an argument to
12334 getpgrp. This simpler test supports the revised documentation,
12335 and is all that AC_FUNC_GETPGRP's users really need.
12337 2001-09-18 Akim Demaille <akim@epita.fr>
12339 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12341 2001-09-18 Akim Demaille <akim@epita.fr>

12344 `{}'.
12345 * lib/autotest/general.m4 (AT_INIT): Adjust.
12347 2001-09-18 Paul Wagland <paul@wagland.net>
12349 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12350 correctly.
12351 Add test for AS_BASENAME.
12352 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12353 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12354 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12355 * tests/base.at: Fixed the expected responses. The old ones were
12356 one line out...
12357 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12358 the documentation claims it should (and how it behaved in 2.13).
12360 2001-09-18 Akim Demaille <akim@epita.fr>
12362 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12363 the AC_CONFIG_COMMANDS invocation.
12364 This also solves the name clash problems.
12365 Don't set the package's ID.
12366 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12367 No longer to be shipped.
12368 (version.in): Remove.
12369 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12370 * lib/autoconf/status.m4: Adjust.
12371 Use `m4_PACKAGE_STRING'.
12372 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12373 the only optional argument is the name of the test suite.
12374 Expect `package.m4' to define the package signature.
12375 * lib/autom4te.in (Autotest): Add `package.m4?'.
12376 * tests/Makefile.am (package.m4): New.
12377 * tests/suite.at: ifnames is a victim.
12379 2001-09-18 Akim Demaille <akim@epita.fr>
12381 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12382 AC_LIBSOURCE, AC_CONFIG_FILES.
12383 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12384 program version string doesn't match the package's.
12385 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12386 after `(cached)'.
12388 2001-09-17 Paul Eggert <eggert@twinsun.com>
12390 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12391 Allow expression to return any value that can fit into unsigned long
12392 (not int, as before). Check for output errors.
12394 2001-09-17 Bruno Haible <haible@ilog.fr>
12396 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12397 Always include <stdio.h> and <stdlib.h>. Evaluate
12398 the expression in an extra function before these includes. Call
12399 fprintf "%d" only after ensuring the argument is of type 'int'.
12400 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12402 2001-09-17 Paul Eggert <eggert@twinsun.com>
12404 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12405 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12406 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12407 when they don't exist.
12409 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12410 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12411 need it.
12413 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12414 version with the version used by fileutils 4.1, except use
12415 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12416 we don't need it.
12418 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12420 2001-09-13 Akim Demaille <akim@epita.fr>
12422 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12423 _first_.
12424 Reported by Gerrit P. Haase.
12426 2001-09-13 Akim Demaille <akim@epita.fr>
12428 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
12429 m4_defn'ing is valid.
12431 2001-09-13 Akim Demaille <akim@epita.fr>
12433 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
12434 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
12435 Use it.
12437 2001-09-13 Akim Demaille <akim@epita.fr>
12439 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
12440 m4_match.
12441 (m4_re_escape): New.
12442 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
12443 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
12444 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
12445 Likewise.
12446 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
12447 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
12448 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
12449 AT_tests_all for consistency.
12450 Set at_victims.
12451 (AT_VICTIMS): Similar to AT_KEYWORDS.
12452 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12454 2001-09-13 Akim Demaille <akim@epita.fr>
12456 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12458 2001-09-13 Akim Demaille <akim@epita.fr>
12460 * lib/autotest/general.m4 (AT_INIT): Create and remove
12461 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12462 test suites can cohabit.
12464 2001-09-13 Akim Demaille <akim@epita.fr>
12466 * tests/mktests.sh: Don't output banners for empty test files.
12468 2001-09-13 Akim Demaille <akim@epita.fr>
12470 Test suites can be run independently of configure.
12472 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
12473 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

12572 2001-09-05 Akim Demaille <akim@epita.fr>
12574 Be ready to handle filenames as stupid as `dnl.at', for if even
12575 the maintainer is dumb enough to do that...
12577 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12578 excellence in M4 quotation: consider `__file__' is active.
12580 And BTW, when invoking m4, pass the --include in the right order:
12581 the wrong one.
12583 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12584 4m.

12608 CVS GNU M4 doesn't like `undefine(undefined)'.
12610 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
12611 New, extracted from main.
12612 Use IO::File wherever possible.
12613 (input.m4): Be constant, use -I instead of hard coding $tmp.
12614 Therefore be a quoted heredoc.
12615 Don't invoke `_au_disable', since ac was not loaded, but just
12616 `unm4.m4'.
12618 2001-08-31 Akim Demaille <akim@epita.fr>
12620 Version 2.52d.

12643 2001-08-31 Akim Demaille <akim@epita.fr>
12645 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12646 (testsuite Scripts): There is no such thing as `atconfig.in'.
12647 And actually one diagram is missing: test suite runtime.
12649 2001-08-31 Akim Demaille <akim@epita.fr>
12651 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12652 inverse order.
12654 2001-08-31 Akim Demaille <akim@epita.fr>
12656 * bin/autoupdate.in (@include): `installcheck' revealed the path
12657 to m4sugar was lacking!
12659 2001-08-31 Akim Demaille <akim@epita.fr>
12661 * man/Makefile.am (.x.1): We really have to pass
12662 autom4te_perllibdir.
12664 2001-08-31 Akim Demaille <akim@epita.fr>
12666 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12667 debug scripts, in particular passing explicitly listed tests to
12668 run is stupid.
12670 2001-08-31 Akim Demaille <akim@epita.fr>
12672 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12673 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12674 Use directly autom4te, not autoconf.
12675 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12677 2001-08-31 Akim Demaille <akim@epita.fr>
12679 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

12688 * bin/autom4te.in (&parse_args): Die on unknown languages.
12689 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12690 need for autoconf.
12691 Promote --include over --macrodir and other obsolete options.
12693 2001-08-31 Akim Demaille <akim@epita.fr>
12695 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

12697 * bin/autom4te.in ($autoconf): Pass --force.
12698 `print $out' doesn't print `$_' but `$out'.
12699 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12700 (autoheader): Pass --force since the test suite goes too fast for
12701 the time stamps.
12702 Adjust to the new autoheader messages.
12704 2001-08-31 Akim Demaille <akim@epita.fr>
12706 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12707 Check the completeness of the #template.

12716 Drop AC_MACRODIR dead for real.
12717 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12718 `autoheader: `config.hin' is created'.
12719 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12721 2001-08-31 Akim Demaille <akim@epita.fr>
12723 * bin/autoheader.in: Rewrite in Perl.
12724 * tests/autoheader: Adjust.
12726 2001-08-31 Akim Demaille <akim@epita.fr>
12728 * bin/autoconf.in (--include, -I): New option.
12729 Map --localdir, --autoconf-dir onto it.
12730 Forward autom4te's options instead of interpreting them.
12731 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12732 There is no such envvar since the inception of autom4te.cfg.
12733 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12734 * bin/autoupdate.in: Adjust, and perform more control.
12735 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12736 * tests/autoconf: Dittowise.
12738 2001-08-31 Akim Demaille <akim@epita.fr>
12740 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
12741 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12742 optionally `FILE'.
12743 Use -e, not -f, since /dev/null for instance is OK.
12744 (&parse_args): Adjust.
12745 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12747 2001-08-31 Akim Demaille <akim@epita.fr>
12749 * configure.ac: Also find tested executables in bin.
12750 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12751 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12752 installed peer executables, only PATH is allowed to resolve it.
12753 Pass `autoconf_dir' via options, not via invisible envvars.
12754 * lib/Autom4te/General.pm (&find_peer): Remove.
12755 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12756 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12757 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12758 find the executables for it.
12759 * tests/Makefile.am: Major cleanup. Too lazy to document...
12760 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12761 We only need PERL.
12762 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12763 indeed related to running the test suite, while passing
12764 --autoconf-dir and others is related to running non installed
12765 Autoconf executables. So don't do that, leave it to...
12766 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12767 * tests/autoscan: New.
12768 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12769 refer to library files: rely on --language.
12771 2001-08-29 Akim Demaille <akim@epita.fr>
12773 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

12776 2001-08-29 Akim Demaille <akim@epita.fr>
12778 * doc/autoconf.texi: Strip the @nodes.
12779 Suggested by Paul Eggert.

12782 2001-08-29 Akim Demaille <akim@epita.fr>
12784 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12785 Suggested by Paul Eggert.
12787 2001-08-29 Akim Demaille <akim@epita.fr>
12789 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
12790 download in a tmp dir.
12792 2001-08-29 Akim Demaille <akim@epita.fr>
12794 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

12806 * bin/autoconf.in: Simplify and adjust.
12807 * tests/Makefile.am (AUTOMAKE): Use --set.
12808 * tests/atlocal.in: Adjust.
12809 * BUGS: distcheck and check are weak.
12811 2001-08-29 Akim Demaille <akim@epita.fr>
12813 * lib/autotest/general.m4: Use
12814 foo=`(command) 2>/dev/null`
12815 not
12816 foo=`command` 2>/dev/null
12817 (at-devnull): Rename as...
12818 (AT-devnull): this.
12819 (--clean): Remove AT-* files too.
12820 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
12821 Reported by Nicolas Joly.

12855 * lib/autotest/general.m4 (AT_INIT): Log the command line.
12856 Support `VAR=VAL' as arguments.

12876 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
12877 `ac_top_builddir' to mimic Automake's vocabulary, which much more
12878 readable.
12879 Adjust callers.
12880 * doc/autoconf.texi (Configuration Actions): Document the vars
12881 available in commands.
12882 Emphasize the risks of collisions in init-cmds.

12917 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
12919 2001-08-27 Akim Demaille <akim@epita.fr>

12965 the name of the directory they're in, instead of the filename,

13257 2001-08-15 Akim Demaille <akim@epita.fr>

13346 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13347 effects.

13367 removed.
13368 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13369 No need to remove the files before and after the each test, before
13370 each test and at the end of the suite is enough.
13371 Display only the children `times', not the shell's.
13372 If the test failed or was skipped, at-times is not available.
13374 2001-08-07 Akim Demaille <akim@epita.fr>
13376 Always produce testsuite.log, including when there are no
13377 failures. This helps getting information on skipped tests, and
13378 duration of the tests. Err, implement the latter btw.
13380 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13381 Dump information on the first run of each test.
13382 (AT_CLEANUP): Create `at-times' containing the duration of the
13383 test group.
13385 2001-08-07 Akim Demaille <akim@epita.fr>
13387 The use of `dumpstat' revealed that `len' was used although it
13388 should not. m4_text_wrap was using it, but in the Autoconf world
13389 where it is legal. Hence (i) test M4sh in its own world, not
13390 Autoconf's, and (ii), ahem, fix the bug :)
13392 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13393 does not like `' instead of [].
13394 (AT_INIT): Forbid `^_?AT_'.
13395 And don't output such tokens.
13396 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13397 `script.as', and `autom4te.cache'.
13398 Remove `empty' and `macro' which are no longer used.
13399 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13400 * tests/m4sugar.at: Use it.
13401 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13403 2001-08-07 Akim Demaille <akim@epita.fr>
13405 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

13409 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13411 2001-08-04 Akim Demaille <akim@epita.fr>
13413 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13414 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13415 AC_TRY_LINK.
13416 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13417 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13418 (AC_F77_MAIN): Likewise.
13420 2001-08-04 Akim Demaille <akim@epita.fr>
13422 Don't rely on M4sugar outputting the patterns in files, since we
13423 might process the output _without_ running m4, hence without these
13424 files.
13426 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13427 * bin/autom4te.in (@Request::includes): Remove, unused.
13428 (@Request::source): Rename as...
13429 (@Request::input): this.

13431 (&handle_output): Fetch the patterns from the traces.
13432 `$forbidden' and `$allowed' are constant: use m//o.
13433 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13434 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13436 2001-08-04 Akim Demaille <akim@epita.fr>
13438 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13439 autoconf', i.e., in addition to caching traces, cache the output.
13441 * bin/autom4te.in (Request::cache): Rename as...
13442 (Request::id): this.
13443 ($cache, $icache, $tcache, $ocache): New.

13452 * bin/autom4te.in ($force): New.
13453 (&parse_args, &print_usage): -f, --force is a new option.
13454 (&handle_output): CPP directives might have spaces after `#'.
13455 (&parse_args): The first file only can be frozen.
13457 2001-08-04 Akim Demaille <akim@epita.fr>
13459 Don't let autom4te compute the `include' traces several times:
13460 first check that the trace cache file is up to date, and then
13461 compare its timestamp with that of the output.
13463 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13464 the preamble. Don't require 5.005 as Autom4te::General does it,
13465 and better yet (use `use', not `require'!).
13466 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13467 Class::Struct as Autom4te::Struct.
13468 * lib/Autom4te/General.pm (File::stat): Use it.
13469 (&mtime): New, export it.
13470 * bin/autom4te.in: Use it.
13471 Declare `$req' is invalid if it is outdated.
13472 Don't declare it valid before saving it if something went wrong.
13474 2001-08-04 Akim Demaille <akim@epita.fr>

13477 must be proposed to the users.

13487 * tests/tools.at (autoconf --trace: user macros): Check traces on
13488 macros invoked without arguments, and macros invoked with multiple
13489 lines arguments.
13491 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13493 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13494 arguments.
13496 2001-08-03 Akim Demaille <akim@epita.fr>
13498 * bin/autoconf.in ($@): Work around the usual sh bug.
13499 From Nicolas Joly.

13523 mismatch happens.
13524 * bin/autom4te.in (&handle_output): Remember of the first
13525 occurrence of a possibly undefined macro, not the last.
13526 Complain about the possibly undefined macros in the same order as
13527 the appear in the output.
13528 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13529 * tests/tools.at (autoconf: forbidden tokens, basic)

13531 autoconf's stderr, as it is now deterministic.
13532 Check that `dnl' is caught.
13534 2001-08-01 Akim Demaille <akim@epita.fr>
13536 * configure.ac: Bump to 2.52c.

13988 provide an alternate 'main' function name, using the 'main' from
13989 the Fortran libraries.
13990 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
13991 cross-language link tests can be performed successfully.
13992 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
13993 after $LIBS, for consistency; this should be the general rule since
