1124 MinGW awk cannot handle 0xFF, and on MinGW, the test does the

1209 Cover more potentially problemtic file names. Use the new
1210 functions.
1212 Properly handle funny file names for headers in config.status.
1213 The test suite did not cover this bug because the code was not
1214 quoting properly the arguments of `rm -f' (which "fails" silently)
1215 as well as the arguments of `diff' (whose output was redirected to
1216 /dev/null so we couldn't see its error message).
1217 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
1218 file names passed to `rm' and `diff'.
1219 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1333 detection...
1334 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1335 argument.
1336 <DEFAULTS>: Delay computation of variables based on $at_dir...

1363 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help

1430 Optimize AC_REQUIRE.

1461 * tests/m4sh.at (LINENO): Quote $0.
1463 Fix testsuite program wrapper for whitespace in `pwd`.
1464 The problem here is that the usual mantra is that command
1465 variables can contain arguments, thus we cannot just escape
1466 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1467 $top_builddir/tests directory early in $PATH, so that the
1468 wrappers are found by their plain name.
1469 * tests/wrapper.as: Put $testdir early in $PATH.
1470 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1472 Proper config.status --file/--header and $srcdir escaping.
1473 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1474 characters in $ac_file_inputs.
1475 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1476 accordingly.
1477 * tests/torture.at (datarootdir workaround): Adjust.
1478 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1480 Fix Autotest for whitespace in `pwd`.
1481 * lib/autotest/general.m4 (AT_INIT)
1482 <at_func_create_debugging_script, Driver Loop>:
1483 Quote $at_group_dir.
1484 * tests/autotest.at (whitespace in absolute testdir): New test.
1486 * lib/autom4te.in: Quote @datadir@.
1488 Proper file name escaping in Autoconf programs and Perl modules.
1489 This includes escaping of characters special to the shell
1490 as well as special to Perl, e.g., leading `<' or `>'.
1491 For example, when $file starts with `>', `open ">$file"'
1492 wrongly tries to append to a different file.
1493 * bin/autoconf.as: Fix quoting for autom4te options.
1494 * lib/Autom4te/General.pm (shell_quote): New function, taken
1495 from coreutils, written by Jim Meyering.
1496 (mktmpdir): Use it.
1497 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1498 and open_quote.
1499 * bin/autoreconf.in (parse_args): Likewise.
1500 * bin/autoscan.in (main): Likewise.
1501 * bin/autoupdate.in (main): Likewise.
1502 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1503 * bin/ifnames.in: Likewise, XFile usage fixes.
1504 * tests/tools.at (autom4te and whitespace in file names): Extend
1505 test. Test twice, with special characters allowed on w32, and the
1506 rest. Test leading and trailing whitespace, for `open_quote'.
1507 (autotools and whitespace in file names): New, analogous test.
1508 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1509 by Russ Allbery and Eric Blake.
1511 Sync from Automake.
1512 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1513 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1514 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1515 (update_file, contents): Use it.
1517 * Makefile.am (autom4te-update): Rewrite for git.
1519 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1521 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1523 Fix copyright years.
1524 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1525 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1527 2007-12-04 Eric Blake <ebb9@byu.net>
1529 Manually resync with gnulib, since 'make cvs-update' no longer works.
1530 * build-aux/config.guess: New upstream version.
1531 * build-aux/config.sub: Likewise.
1533 When using older automake, don't downgrade build-aux/texinfo.tex.
1534 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1535 * doc/Makefile.am (TEXINFO_TEX): Add.
1537 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1539 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1540 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1541 #undef as this runs afoul of our new way of creating config.h.
1542 Problem reported by Jim Meyering in
1543 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1548 * bin/autom4te.in (files_to_options): Quote active characters
1549 for the shell.
1550 * tests/tools.at (autom4te and white space in file names):
1551 New test.
1553 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1554 Document that Tru64 awk always splits $0.
1556 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1558 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1559 `#AT_STOP_...' line at the end of each test.
1561 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1563 * lib/autotest/general.m4 (AT_INIT): For awk line number
1564 extraction script, ensure `$at_group' has a defined value
1565 even for the empty set, and properly quote its usage inside
1566 the awk script.
1568 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1570 * doc/autoconf.texi (Shell Functions): New chapter. Document
1571 IRIX sh $0 issue in functions, move content from ...
1572 (Portable Shell): ... here.
1573 (Shell Script Compiler): Note that shell functions are not
1574 totally unportable any more.
1576 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1577 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1579 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1580 extracting the line numbers of the last needed test.
1582 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1584 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1585 Fix quoting.
1587 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1589 Fix IRIX testsuite debugging failures: $0 in functions.
1590 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1591 Do not use $0 inside a function, as IRIX sh will set that to the
1592 function name rather than the script invocation name.
1594 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1595 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1597 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1598 to extract test scripts.
1599 (AT_INIT): Extract and cache test script line numbers.
1601 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1603 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1604 subsequent fixups; the awk -> here-document conversion trashes
1605 performance too much with AIX sh.
1607 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1609 * tests/local.at: Do not test m4, perl with AT_TESTED.
1611 Diagnose and guard against write errors dealing with config.status.
1612 The general idea is this: all write failures from `configure'
1613 writing `config.status' are indicated by $ac_write_error, which
1614 is only checked at the end. This is safe because config.status
1615 code is not executed before the file is complete. Other write
1616 failures, be they inside config.status, or in sub shell/awk
1617 scripts spawned from configure or config.status, typically need
1618 earlier checking, as their results are used right afterwards.
1619 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1620 before writing config.status, check afterwards.
1621 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1622 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1623 Set `ac_write_error' for write failures to config.status. Barf
1624 upon write failures to temporary files.
1625 Adjust note about closing and reopening the here-document.
1626 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1627 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1628 reopening the here-document.
1629 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1630 Ensure `ac_write_error' does not escape into config.status.
1631 Also, add a couple of code paths not yet exercised in the test
1632 suite: a config file with input from stdin, and a config header
1633 output to stdout.
1634 Suggestion for catching write errors by Bruno Haible.
1636 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1638 Avoid error with Tru64 awk and testsuite lines with many words.
1639 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1640 reads the testsuite, set the field separator to an unusual value,
1641 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1642 even splits the input if $i, i>0, was never accessed in the script.
1644 Revert 2007-10-17 change.
1645 * TODO: Multiline args in config files and headers mean something
1646 different and are not fixed, see
1647 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1648 Report by Stepan Kasal.
1650 * doc/autoconf.texi (Generic Programs): Fix typo.
1652 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1654 AC_*_TOOL does not canonicalize the prefix
1655 * doc/autoconf.texi (Generic Programs): Do not say that
1656 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1658 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1660 Diagnose write errors in config.status instantiations.
1661 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1662 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1663 on write errors.
1664 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1665 Extend test to also check for some write error failures, using...
1666 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1667 Report by Bruno Haible.
1669 Indentation fixups.
1670 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1671 indentation.
1672 (_AT_CHECK): Use less indentation, to save space.
1674 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1676 Add witness macro for @top_build_prefix@ substitution.
1677 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1678 (_AC_OUTPUT_FILE): Mention it here.
1680 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1681 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1683 * lib/autotest/general.m4 (at_func_test): Remove.
1684 (AT_INIT): Pre-extract test groups into separate files.
1685 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1686 Remove at-test-source files together with the $at_group_dir.
1687 * tests/autotest.at (Long test source lines): New test.
1689 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1691 Shell functions and variables may share a namespace.
1692 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1693 limitation.
1695 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1697 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1698 gnulib.
1700 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1702 * lib/autoconf/status.m4: Fix a couple of comment typos.
1704 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1706 2007-11-13 Jim Meyering <meyering@redhat.com>
1708 Clean up the rule to create "expr".
1709 * tests/Makefile.am (expr): Don't redirect directly to target.
1710 Redirect just once, not for each echo statement.
1711 Use $@, not literal "expr".
1713 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1715 Don't worry about preprocessor when testing long long.
1716 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1717 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1718 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1719 These no longer check for preprocessor flaws.
1720 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1721 Do not check for preprocessor flaws.
1723 2007-11-13 Jim Meyering <meyering@redhat.com>
1725 Adapt dependencies, now that a version change doesn't modify configure.ac
1726 * GNUmakefile: Remove "make clean" kludge.
1727 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1728 configure.ac.
1729 Don't redirect directly to target.
1730 Use $@, not literal "version.m4".
1732 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1734 * doc/autoconf.texi (Making testsuite Scripts): Document
1735 ":;{" shorthand as in previous patch.
1737 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1739 * doc/autoconf.texi (Limitations of Builtins): Document problem
1740 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1741 for the workaround.
1742 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1743 Use ":;{" shorthand.
1744 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1746 2007-11-12 Jim Meyering <meyering@redhat.com>
1748 Add more non-srcdir build support.
1749 * GNUmakefile (dummy): Split a long line.
1750 Add -v option to autoreconf invocation.
1752 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1753 * GNUmakefile (dummy): Remove INSTALL.
1755 Remove racy commands to build scripts in bin/ and tests/.
1756 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1757 are guaranteed to be built, remove the rules that tried to build
1758 them. Before, with a parallel build, these rules could lead to
1759 two processes writing tests/wrapper.in concurrently.
1761 Build in man/ only *after* building in bin/ and tests/.
1762 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1763 in both bin/ and tests/.
1765 Accommodate non-srcdir build-from-checkout.
1766 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1767 Use git's --git-dir=$srcdir/.git option.
1768 Add quotes, in case tarball_version_file contains shell meta-characters.
1769 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1770 * configure.ac: Pass "." to git-version-gen.
1772 Avoid spurious test failures due to version skew.
1773 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1775 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1777 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1778 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1779 Remove conftest.dSYM directory.
1780 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1781 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1782 Remove `conftest.*' recursively.

1784 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1785 Likewise.
1786 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.

1797 Document that $((expression)) is not portable.
1798 * doc/autoconf.texi (Shell Substitutions): Here.
1800 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1802 Ignore configure --help* errors due to LINENO-impaired shells.
1803 * tests/torture.at (Configuring subdirectories, Deep Package):
1804 In the --help* tests in read-only trees, make `.' temporarily
1805 writable again for the `stderr' file, and ignore errors due to
1806 the attempt to write configure.lineno.
1807 Report by Patrick Welche.
1809 2007-11-10 Jim Meyering <meyering@redhat.com>
1811 Generate package.m4 in build-dir, not srcdir.
1812 * tests/Makefile.am (package.m4): Adjust target.
1813 Don't redirect directly to $@.
1814 (CLEANFILES): Add package.m4.
1815 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1816 in $(srcdir).
1817 When running $(AUTOTEST), search "." before searching $(srcdir).
1819 Avoid a race condition that would make parallel "distclean" fail.
1820 * tests/Makefile.am (distclean-generic): Replace the default,
1821 automake-provided rule with an identical one, but with an additional
1822 dependency on distclean-local. Simply adding the dependency would
1823 cause automake not to emit the rule at all.
1824 * BUGS: Building with -jN works, now.
1826 Distribute git-version-gen.
1827 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1828 since GNUmakefile is distributed, and requires it for dist* rules.
1830 Remove two more generated files from version control.
1831 * INSTALL: Remove generated file.
1832 * lib/autoscan/autoscan.list: Remove generated file.
1834 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1836 * GNUmakefile (PATH): Remove stray apostrophes; they become
1837 part of PATH, which isn't wanted here.
1839 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1841 New config files output variable `top_build_prefix'.
1842 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1843 `top_build_prefix'.
1844 * doc/autoconf.texi (Preset Output Variables): Document it.
1845 * NEWS: Update.
1846 Report by Bob Friesenhahn.
1848 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1849 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1850 function, to parametrize arithmetic with expr vs. the shell.
1851 Use it where possible.
1852 Suggestion by Benoit Sigoure.
1854 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1856 Adjust the documentation of autotest WRT atlocal.
1857 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1858 when using Automake, to write a rule to produce atlocal, since it's
1859 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1860 distributed, not atconfig.in.
1862 2007-11-04 Eric Blake <ebb9@byu.net>
1864 Update list information.
1865 * README: Mention new autoconf-commit list.

1880 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1881 * build-aux/git-version-gen: This syncs from coreutils.
1883 Adjust the build procedure so "make check" works reliably.
1884 * README-hacking: Include an extra step between "make" and
1885 "make check" to ensure that the latter passes.
1887 Use just-built tools, when possible.
1888 * GNUmakefile (PATH): Set and export here, ...
1889 (dummy): ... rather than here.

1910 workaround.
1912 2007-11-03 Eric Blake <ebb9@byu.net>
1914 Support m4 1.4.5 in testsuite.
1915 * tests/torture.at (Define a newline): Exclude line numbers in

1934 * doc/autoconf.texi (Number processing Macros)
1935 <m4_version_compare>: Document this change.
1936 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1938 2007-10-30 Bruno Haible <bruno@clisp.org>
1940 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1941 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1942 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1943 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in

1957 Suggestions from Ralf Wildenhues.
1959 2007-10-28 Jim Meyering <meyering@redhat.com>
1961 Make inter-release --version output more useful.
1963 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1964 which indicates that it is built using the 19th change set
1965 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1966 is a prefix of the commit SHA1.
1967 * build-aux/git-version-gen: New file.
1968 * configure.ac: Run it to set the version.
1969 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1970 * Makefile.am (dist-hook): Arrange so that .version appears only
1971 in distribution tarballs, never in a checked-out repository.
1972 * .gitignore: Add .version here, too. Just in case.
1973 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1974 not configure.ac, now that the version number changes automatically.
1976 Ensure that $(VERSION) is up to date for dist-related targets.
1977 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1978 git-version-gen doesn't match $(VERSION), but only for dist targets.

2024 Use -1ull rather than -1u, since that causes problems with gnulib; see
2025 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

2049 this resolution. Fixes test failure on FreeBSD.
2051 Fix config header generation with AIX awk.
2052 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

3234 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

3254 for C++; this drops support for anonymous struct and union types,
3255 which were problematic anyway.

3275 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3276 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3277 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3278 works but the latter doesn't, then it's a valid type.
3279 This lets people use function types and so forth.
3280 For C++ there doesn't seem to be a simple solution, so leave it alone.
3281 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3282 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3283 AC_CHECK_TYPE; that wasn't documented or necessary.

3344 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3346 * doc/autoconf.texi (Specifying Names): `--host' does not

3361 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
3362 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3363 universal binaries. Problem reported by Elias Pipping.
3365 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3367 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3368 * doc/autoconf.texi (C Compiler): Document this. There is a new
3369 extra argument ACTION-IF-UNIVERSAL.
3370 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3371 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3372 Reindent for sanity's sake.
3374 2007-02-24 Eric Blake <ebb9@byu.net>
3376 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3377 copyright.
3378 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
3379 * lib/autotest/general.m4 (AT_INIT): Likewise.
3380 (_AT_DECIDE_TRACEABLE): Fix syntax highlighting.
3382 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3384 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3385 status of rm so we know when it failed.
3386 If cleaning of test dir failed before running the test, warn.
3387 Output the line separator in verbose mode before the warning
3388 to make clear the warning belongs to the following test.
3390 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3392 * doc/autoconf.texi (Parentheses): Mention problem with (( in
3393 shells.

3399 errors introduced in last change.
3401 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3403 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
3404 an actual carriage return. Use "ac_cr" to contain the actual
3405 carriage return.
3406 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3407 with traditional Awk and begin.
3408 * tests/torture.at (Limitations of Builtins): Document the problem
3409 with Bash 2.03 printf.
3410 (Substitute and define special characters):
3411 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
3413 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3415 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3416 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3417 will not wait for input with a script containing only a BEGIN
3418 rule.
3420 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3422 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

3440 * THANKS (people): Update.
3442 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3444 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3445 latest version.
3446 (Shell Substitutions): Note problems with @{var:=value} etc.
3447 Add a new section for problems with @{#var} etc. Problem noted
3448 by Ralf Wildenhues. See:

3451 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3453 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3454 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3455 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3456 substitution will still be done by the special code.
3457 Report by Jim Meyering.
3459 * doc/autoconf.texi (File System Conventions): Mention that
3460 $PATH_SEPARATOR is for the build system only.
3461 Report by Keith Marshall.

3471 Test all 8 bit non-NUL characters.
3472 Report against Automake by Patrick Welche.
3474 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3476 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3478 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3480 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3481 early on the reader side, drop stderr of the input to avoid
3482 `broken pipe' error output; this may happen even with shell
3483 builtin `echo' of some bash versions. Reports by Ian Macdonald
3484 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3486 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3488 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3489 separate items of `ac_user_opts', to avoid long lines.
3490 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3492 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3494 * doc/autoconf.texi: Fix some typos.
3496 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3498 Fix some wording problems noted by Paolo Bonzini in:
3499 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3500 * doc/autoconf.texi (Signed Overflow Examples): Give more
3501 discussion about the allow_superuser_privileges example,
3502 and change it a bit to make things clearer.
3503 (Optimization and Wraparound): Clarify whether the compiler
3504 will generate an infinite loop for the example derived from
3505 Autoconf's mktime test.
3506 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3507 Also, clarify unsigned multiplication overflow.
3509 2007-01-04 Eric Blake <ebb9@byu.net>
3511 * bin/Makefile.am (RELEASE_YEAR): New macro.
3512 (edit): Use it to supply correct copyright year to scripts.
3513 * bin/autoconf.as (version): Use it.
3514 * bin/autoheader.in ($version): Likewise.
3515 * bin/autom4te.in ($version): Likewise.
3516 * bin/autoreconf.in ($version): Likewise.
3517 * bin/autoscan.in ($version): Likewise.
3518 * bin/autoupdate.in ($version): Likewise.
3519 * bin/ifnames.in ($version): Likewise.
3521 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3523 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3524 feedback. The most important changes document what happens when
3525 you convert an out-of-range value to a signed integer type, and
3526 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3527 a + b.
3529 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3530 rewrite, taking notions from the recent discussion on the gcc and
3531 autoconf mailing lists; please see
3532 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3533 and follow the many links.
3534 (Integer Overflow Basics, Signed Overflow Examples):
3535 (Optimization and Wraparound, Signed Overflow Advice):
3536 (Signed Integer Division): New sections.
3538 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3540 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3541 preprocessor macro arguments in traced name.
3542 * doc/autoconf.texi (Defining symbols): Document longstanding
3543 support for AC_DEFINE-ing macros with arguments, and document
3544 behavior when the same variable has multiple AC_DEFINEs.
3545 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3546 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3547 macros directly, giving much shorter and simpler code.
3549 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3551 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3552 space before "$ac_configure_args" to prevent a 'config.status
3553 --recheck' failure if ac_configure_args doesn't contain a leading
3554 space. This works around a problem with the XEmacs configure.ac,
3555 which uses the (undocumented) ac_configure_args variable
3556 inconsistently with Autoconf.
3558 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3560 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3561 Include <limits.h>, and use its INT_MAX to rewrite the
3562 j loop so that it does not overflow 'int'. Problem reported by
3563 Ralf Wildenhues in
3564 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3565 Play it safe by shifting left by 1 rather than multiplying by 2,
3566 as GCC is less likely to optimize this away when the value
3567 is signed (when it assumes overflow leads to undefined behavior).
3568 Also, don't assume time_t uses two's complement.
3570 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3572 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3573 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3574 dumps core on it. Report by Tim Rice.
3576 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3578 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3579 --disable-option-checking to --help output even when
3580 AC_PRESERVE_HELP_ORDER is not used.
3581 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3582 --with argument, rather than argument with [-.] replaced by
3583 underscores.
3584 * NEWS: Fix typo in previous change; the news was in the
3585 wrong section.
3587 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3589 * NEWS: Warnings are now generated by default for unknown
3590 --enable-* and --with-* options.
3591 * doc/autoconf.texi (Option Checking): Renamed from
3592 (Configure Option Checking). Tighten up the wording a bit.
3593 (External Software, Package Options): Cross-reference to Option
3594 Checking, and use this to shorten our section.
3595 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3596 "$x" to test "x$foo" != x.
3597 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3598 Don't warn if $enable_option_checking is "no".
3599 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3600 ac_unrecognized_opts to the empty string.
3601 Don't echo the unrecognized opts, as this might mishandle
3602 backslashes or leading -.
3603 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3604 usage next to the other --disable-FEATURE options in the
3605 help string.
3607 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3609 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3610 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3611 Print warning for unrecognized --with and --enable options
3612 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3613 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3614 Disable option checking when subdirs are configured.
3615 (AC_OUTPUT): If warnings are enabled, print warning about
3616 unrecognized --with and --enable options at the end of
3617 the configure output (as well as at the beginning).
3618 * doc/autoconf.texi (Option Checking): New node.
3619 Document new option warning functionality.
3621 2006-12-16 Eric Blake <ebb9@byu.net>
3623 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3624 * NEWS: Start news for current version.
3626 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3628 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3629 Define HAVE_GETMNTENT to 1, not to the empty string.
3630 Problem originally reported by Jochen Friedrich in
3631 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3633 This change prompted by a problem report by Andrey Simonenko in
3634 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3635 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3636 object-like macros only, in the traditional portable character
3637 set.
3638 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3639 Warn about attempts to define things that are not identifiers.
3640 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3641 awful hack that AC_DEFINEd macro names containing parentheses.
3643 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3645 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3646 too drastic, even if Texinfo in theory requires it for info mode.
3648 (config.status Invocation): Renamed back from Recreating a
3649 Configuration).
3650 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3651 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3653 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3655 * NEWS: Version 2.61a.
3657 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3658 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3660 * NEWS: Document changes with echo and printf, and the lack
3661 of limits on the total size of multi-line values of substituted
3662 variables, and the AC_FUNC_FSEEKO fix.
3664 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3666 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3667 Writing configure.ac.
3668 (Autoconf Input Layout): Renamed from configure.ac Layout.
3669 (Recreating a Configuration): Renamed from config.status Invocation.
3670 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3671 (acconfig Header): Renamed from acconfig.h.
3672 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3673 (Writing Testsuites): Renamed from Writing testsuite.at.
3674 (Autom4te Cache): Renamed from autom4te.cache.
3676 * BUGS: Remove mention of VPATH problem, since it's now documented
3677 not to be a bug in the Autoconf build procedure itself, but rather
3678 a problem with the proprietary `make' programs.
3680 * doc/autoconf.texi (Build Directories): Add a cross reference
3681 to VPATH and Make.
3683 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3684 * doc/standards.texi: Sync from gnulib.
3686 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3687 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3688 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3689 generated automatically.
3691 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3693 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3694 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3695 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3697 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3699 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3700 `CEOF$ac_eof' special marker, the awk script cannot contain a
3701 line matching `^CEOF', so this is not needed any more.
3702 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3703 special marker in the test.
3705 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3707 * tests/tools.at (autom4te preselections): Use `find -newer';
3708 remove one of the sleeps.
3710 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3711 more readable, using ...
3712 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3714 * doc/autoconf.texi (autoheader Invocation): Do not double-
3715 quote the parameter of `AH_BOTTOM' in the example.
3717 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3719 * doc/autoconf.texi (Configuration Headers): Remove the
3720 example with multiple input files.
3721 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3722 multiple input files.
3724 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3726 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3727 creating the awk substitution script, handle one input line at a
3728 time, so that the maximum length of a substituted (multi-line)
3729 value is not limited by the size of the sed pattern space.
3730 The trade-off is a slightly repetitive sed script.
3731 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3732 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3733 * tests/torture.at (Substitute a 2000-byte string): Increase the
3734 test with several long lines, they should not be caught by sed
3735 limits any more.
3737 * tests/tools.at (autom4te preselections): New test, to flag
3738 entries missing from autom4te.cfg.
3739 Report by David Byron <dbyron@hheld.com>.
3741 * tests/torture.at (Substitute a 2000-byte string): Actually use
3742 AC_PROG_AWK, so the last change works as intended.
3743 (Substitute and define special characters): Likewise.
3744 (Substitute a newline): Likewise.
3746 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3747 instead of `awk' consistently.
3748 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3749 * tests/torture.at (Torturing config.status): Test both the
3750 result of AC_PROG_AWK and plain awk.
3751 (Substitute a 2000-byte string): Likewise.
3752 (Substitute and define special characters): Likewise.
3753 (Substitute a newline): Likewise.
3755 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3757 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3758 can be assigned to a function pointer. Problem reported by
3759 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3760 part of a patch by Ralf Wildenhues in that same bug report.
3762 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3764 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3765 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3767 2006-12-01 Eric Blake <ebb9@byu.net>
3769 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3770 cross-compiling from cygwin to mingw.
3771 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3772 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3773 to lib/autoconf/c.m4.
3775 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3777 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3778 string for more reliable failure. Wrap the entire test that
3779 causes the broken Solaris printf to dump core, in a subshell,
3780 so the segmentation fault message is reliably suppressed.
3781 Fix shell expansion errors by using /usr/ucb/echo always;
3782 avoid an error on systems without it by another subshell.
3783 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3784 subshell-$as_echo to `as_echo', for better error message.
3786 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3788 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3789 `BASH_SOURCE' contain a newline, set them to empty, as they may
3790 not be unset.
3792 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3794 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3795 years and is too hard to maintain now. The last straw was
3796 reported by Jerker Baeck in
3797 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3798 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3799 * doc/autoconf.texi (Particular Functions): Move
3800 AC_FUNC_SETVBUF_REVERSED from here...
3801 (Obsolete Macros): ... to here. Say that it does nothing now.
3802 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3803 Turn into (almost) a no-op.
3805 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3806 (AC_C_VOLATILE):
3807 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3808 These macros are obsolescent and new applications shouldn't need them.
3809 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):

3820 Ralf Wildenhues.
3821 * NEWS: Mention this.
3823 * Makefile.am: Put only a single '#' into the copyright notice,

3839 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3841 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3842 in the sed script that mangles the awk script: delete up to the
3843 first exclamation mark only.
3844 * tests/torture.at (Substitute and define special characters):
3845 Test '!' too.
3847 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3849 Rewrite config files generation: avoid quadratic growth in
3850 the number of substituted variables by using awk instead of sed
3851 for the bulk of the substitutions.
3852 * NEWS: Mention this.
3853 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3854 forbidden in the output (and thus input) file.
3855 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3856 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3857 generate just one large awk script for substitutions,
3858 eliminating much of the earlier complexity, while adding some
3859 new complexity. Only expand the substitution templates at
3860 configure time, for smaller configure script size. If
3861 _AC_SUBST_FILES are used, test 'awk' for working getline support
3862 at config.status time. If absent, interpolate through the
3863 shell. The awk script was written with much help
3864 from Paolo Bonzini and Paul Eggert.
3865 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.

3870 * tests/torture.at (Substitute a 2000-byte string): Also
3871 substitute a line with 1000 words, and a variable with several
3872 long lines.
3873 (Substitute and define special characters): Test awk special
3874 characters, and put substitution input strings `@foo@' in the
3875 output, to test that no recursion happens; test several other
3876 combinations from Paolo Bonzini.
3878 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3880 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3881 that replaced echo with AS_ECHO where this wasn't necessary.
3882 Problem reportd by Ralf Wildenhues.
3883 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3884 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3885 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3887 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3889 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3891 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3893 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3894 that traditional Awk lacks 3-arg "split". It has it.
3895 Mention that FS must be a single character, and a few other
3896 99-byte limits of traditional Awk.
3897 Mention that if (i in a) doesn't work with traditional Awk.

3906 Use printf '%s\n' instead of echo, for portability to hosts
3907 where echo interprets backslashes. This will break on hosts
3908 that lack printf, but for now let's assume all such hosts
3909 are dead (if not, we should get reports of test failures).
3911 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3913 'echo' has some portability problems, when given a first argument
3914 with a leading '-', or when given any argument containing '\'.
3915 Avoid using 'echo' in these cases.

3950 use AS_ECHO.
3951 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3952 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use

4094 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4095 and Stepan Kasal <kasal@ucw.cz>
4097 Handle special characters in test case titles correctly.
4098 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4099 properly.
4100 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4101 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4102 argument. Extend to check titles printed by ./micro-suite and
4103 ./micro-suite -l and the title in micro-suite.log.
4104 (Backquote in a test title,
4105 Single-quote in a test title,
4106 Double-quote in a test title): Don't expect failure anymore.
4107 (Backslash in a test title): Put a non-whitespace character after the
4108 backslash so that Bourne shells might actually see it as an escape
4109 sequence.
4110 (Brackets in a test title,
4111 Pound in a test title,
4112 Comma in a test title,
4113 Quoted Macro in a test title,

4120 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4121 The visible effect was a stray [] in the testsuite output.
4123 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4125 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4126 `trap ... 0' inside a function, for AIX sh.
4128 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4130 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4131 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4132 5363) simply issues a warning when dividing by zero at compile
4133 time. Problem reported by Elias Pipping.
4135 2006-10-26 Eric Blake <ebb9@byu.net>
4137 * THANKS: Update.
4138 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4139 show effect on macros that expand with commas.
4140 Reported by Joel E. Denny.

4168 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4169 reported by Nelson H. F. Beebe for Coreutils 6.4.
4171 * tests/tools.at (autoconf --trace: user macros): Remove test
4172 for tracing multiline macros, since m4 1.4.7a uses a different
4173 way to number lines. Problem reported by Ralf Wildenhues.
4175 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4177 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4178 /dev/null since the heuristics for interactive behaviour was
4179 fixed in CVS m4.
4181 * bin/autom4te.in: With --force, always refresh the output
4182 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

4204 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4206 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4249 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4251 (Imported from Automake.)
4252 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4253 which incorrectly sets the mode of an existing destination
4254 directory. In some cases the unpatched install-sh could do the
4255 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4256 system. We hope this is rare in practice, but it's clearly worth
4257 fixing. Problem reported by Alex Unleashed in
4258 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4259 Also, don't bother to check for -m bugs unless we're using -m;
4260 suggested by Stepan Kasal.

4321 by Ralf Wildenhues.
4323 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4325 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4326 AC_PROG_CC.
4327 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4329 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4331 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4332 the NonStop platform.
4333 * doc/autoconf.texi (Posix Variants): Likewise.
4334 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4336 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4337 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4338 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4339 Use a better substitute, by inspecting the output of "ls"
4340 rather than just using ":".
4341 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4342 rather than AS_EXECUTABLE_P, since we needn't worry about
4343 non-regular files here.
4345 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4346 due to configuration hassles with this. See Tonya Underwood's report
4347 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4348 * doc/autoconf.texi (Special Shell Variables): Likewise.
4350 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4351 Stepan Kasal <kasal@ucw.cz>
4353 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4354 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4356 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4358 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4359 initialization which is not inherited through the environment
4360 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4361 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4363 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4365 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4366 problems with mkdir -p -m.
4368 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4370 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4371 comment about ac_cpp_err; it was incorrect, and anyway
4372 ac_cpp_err is being removed below.
4373 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4374 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4375 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4376 nobody uses it.
4377 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4378 with werror_flag and conftest.err and so forth. This is more
4379 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4380 and anyway the user shouldn't normally want to see this gorp logged.
4381 Problem reported by Ralf Wildenhues.
4382 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4383 empty, not 'no', since the rest of the code uses 'test -z'.
4385 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4387 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4388 Use a single call to AC_DO_TOKENS rather than multiple, for
4389 efficiency.
4390 (_AC_LINK_IFELSE): Test that resulting file is executable.
4391 Problem reported by mwoehlke in
4392 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4394 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4395 than creating a file to use with test -x; this is much faster.
4397 2006-10-02 Bruno Haible <bruno@clisp.org>
4399 * lib/autom4te.in (Automake-preselections): Add
4400 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4402 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4404 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4405 standard error, `experr' should be used, not `expout'.
4407 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4409 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4410 fseeko testing program twice; just use the earlier result.
4411 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4412 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4413 still doesn't let the program compile.
4414 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4415 failed.
4417 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4418 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4419 include it, without including anything else.
4420 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4421 expressions.
4422 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4424 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4426 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4427 `error.h', and include it, for a `error_at_line' prototype.
4428 Use a nonempty format string in the link test.
4429 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4430 for a declaration of wait3.
4432 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4434 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4435 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4436 can apply to constants too, and that it checks for macro defns.
4437 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4438 and simply cast the identifier to void. This handles structure
4439 values. Problem reported by Ralf Wildenhues.
4440 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4442 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4444 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
4445 structure, and function symbols.
4447 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4449 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
4450 member.
4452 2006-09-25 Paul Eggert <eggert@cs.ucla.edu>

4461 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
4462 warnings (uninitialized value).
4463 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
4464 present.
4465 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

4474 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.
4475 Report by Olly Betts.
4477 2006-09-19 Eric Blake <ebb9@byu.net>

4495 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
4496 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
4497 --error-output, to avoid warnings with M4 2.0.
4499 2006-09-19 Stepan Kasal <kasal@ucw.cz>
4501 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
4502 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
4503 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
4505 2006-09-15 Stepan Kasal <kasal@ucw.cz>
4507 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Eliminate the
4508 expansion of AC_CHECK_FUNCS.
4510 2006-09-14 Stepan Kasal <kasal@ucw.cz>
4512 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
4513 mistaken comment: the path has to be relative; do not use
4514 the path at runtime.
4516 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4518 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the
4519 argument to `--prefix' for sub-configure scripts.

4522 for both changes.
4523 * doc/autoconf.texi (Setting Output Variables): Fix example to
4524 not show `--silent' being passed to a `configure' re-run.
4526 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4528 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
4529 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
4530 for the existence of the directory at configure-time. That's
4531 too late, anyway. Problem reported by Stefan Seefeld.
4533 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4534 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4535 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4537 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4539 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4540 works with GNU M4 1.4.3 again; make the normalized form
4541 match the current m4 message; fix the description.
4542 * test/tools.at (autom4te cache): Adapt to the change.
4544 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4546 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4547 to catch glibc bug 2821
4548 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4550 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4551 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4552 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4553 assume C89.
4555 2006-09-08 Stepan Kasal <kasal@ucw.cz>
4557 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

4573 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4575 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4576 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4577 accept files with extension `.f'. For consistency, also prefer
4578 xlf over f77.
4579 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4580 from last patch.
4582 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

4597 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
4599 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
4600 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
4601 except the first two arguments are reversed.
4602 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4603 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4604 caches nor outputs a diagnostic. Suggested by Bruno Haible.
4605 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
4606 equivalent to the old AC_COMPUTE_INT.
4607 (AC_COMPUTE_INT): No longer caches or reports. New signature.
4608 All uses changed to AC_CACHE_CHECK_INT.
4609 * tests/base.at (AC_CACHE_CHECK_INT): New test.
4610 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
4612 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
4614 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4615 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4616 programs should use their Gnulib counterparts.
4617 * doc/autoconf.texi (Particular Functions): Likewise.
4618 (Macro Names, testsuite Invocation): Replace uses of these
4619 obsolete macros with uses of non-obsolete macros.
4621 2006-08-29 Eric Blake <ebb9@byu.net>
4623 * configure.ac (AC_INIT): Bump to 2.60b.
4624 * NEWS: Update.

4647 Fix Lex library problem reported to us by Julio Garvia.
4648 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
4649 for the default, which the user can override.
4650 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4651 deal with LEXLIB.
4652 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4653 didn't work if some values were cached but not others. Test for
4654 broken lex libraries like native ia64-hp-hpux11.22; see
4655 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4656 work around the problem by preferring an empty LEXLIB to -lfl or
4657 -ll. Let the user set LEXLIB='' to indicate no library needed.
4659 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4660 * README: Likewise.
4661 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4722 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
4723 Also check for -Wpointer-arith.
4724 (WGET, WGETFLAGS, tgz-md5, tgz-sha1, bz2-md5, bz2-sha1):
4725 (xdelta-md5, xdelta-sha1, tgz-size, bz2-size, xd-size, rel-check):

4756 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
4757 64-bit preprocessor ints. Check for static initialization of
4758 long long. Remove unnecessary casts.
4760 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4762 * doc/autoconf.texi (Particular Programs): Mention that
4763 @INSTALL@ and @MKDIR_P@ may vary for different output files.
4764 Reported by Alexandre Duret-Lutz.
4766 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
4768 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
4769 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
4770 Bill Northcott in
4771 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
4773 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
4775 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
4776 pacify insanely picky compilers. Problem reported by Eric Blake.
4778 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
4779 longer supported by Sun.
4781 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
4783 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4784 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4785 -Wundef -Werror". Problem reported by David Fang in
4786 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

4802 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
4803 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
4804 this.
4806 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
4808 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
4809 problems with arg script text that doesn't end in newline, and
4810 with '-e a...'. Problems reported by Ralf Wildenhues.
4812 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4814 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
4815 check for libXt by a check for libX11.
4817 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4819 * doc/autoconf.texi (config.status Invocation): Adjust according
4820 to last change.
4822 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4824 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
4825 --help' should mention that `--version' outputs configuration
4826 settings. Report by Bruno Haible.
4828 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4830 Fix test suite failures reported by Pierre in
4831 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
4832 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
4833 the compiler created a file "b.out" when it didn't create anything
4834 at all.
4835 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
4836 Discard stderr too, when invoking the test script.
4838 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
4840 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
4841 in the restoring of the werror flag.
4843 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4845 * doc/autoconf.texi (Volatile Objects): Be even a little
4846 less skeptical about "volatile", after discussion with
4847 Bruno Haible on bug-gnulib.
4848 (Limitations of Usual Tools): Warn about sed stripping
4849 leading white space from text. From Bruno Haible.
4851 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4853 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4854 compiler complains about it, even if things works after the
4855 complaint. Problem reported by Peter O'Gorman.
4857 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4858 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4859 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4861 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4863 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4864 after -R regardless of host. Patrick Welche reports that this
4865 fixes things on NetBSD 3.99.

4871 to match M4 1.4.5.
4873 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4875 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4876 under AC_C_VOLATILE.
4877 (Volatile Objects): Be a little less skeptical about what
4878 "volatile" means. Derived from thoughts by Ben Pfaff in
4879 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4881 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4883 * doc/autoconf.texi: Fix some typos.
4885 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4887 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4888 more globally, since the 2006-06-30 patch didn't suffice. Problem
4889 reported by Keith Marshall. Also, don't bother with builddir2,
4890 since it shouldn't be needed any more.
4892 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4894 * doc/autoconf.texi (Generic compiler characteristics):
4895 Document AC_COMPUTE_INT. Fix wrong statements on Default
4896 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
4898 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
4899 (_AC_COMPUTE_INT): Add obsoletion warnings.

4901 AC_COMPUTE_INT.
4903 * NEWS: Document change.
4905 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
4907 * doc/autoconf.texi (Volatile Objects): New section.
4909 * NEWS: Document previous change.
4911 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4913 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4914 Require that long long int be at least 64 bits wide. C99 requires
4915 this and enough programs depend on it so we should check for it.
4916 Bruno Haible reports in
4917 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4918 that long long int is 32 bits wide with some nonstandard compilers.
4919 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4921 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4923 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4924 to a nonexistent file, so that we don't have to worry about
4925 a local site configuration that doesn't use /usr/local.
4926 Problem reported by Keith Marshall in
4927 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4929 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4931 * doc/autoconf.texi: Be more consistent about using @acronym with
4932 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4933 quite right (it talked about "OSF/Tru64", even though the
4934 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4935 and it even mentioned "OSF 4"!) and at this point there's little
4936 reason to talk about OSF any more, since it died in 1994.
4937 (Specific Compiler Characteristics): Simplify example of
4938 negative-size array.
4939 (File Descriptors): Reorder to make the text flow better.
4940 Remove joke about "appreciate the various levels"; I didn't get it.
4941 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4942 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4943 (File Descriptors, Limitations of Usual Tools):
4944 Tone down the advice against renaming or removing open files.
4945 (Limitations of Usual Tools): Add a new section, on 'rm'.
4947 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4949 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4950 -lXt in LIBS, idea from Karsten Hopp; this was due since
4951 this change:
4953 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4954 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4955 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4956 (which belong to Xt, not X itself). See Debian bug 327655.
4958 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4960 * configure.ac (AC_INIT): Bump to 2.60a.
4961 * NEWS: Update.
4963 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4965 Version 2.60.
4967 * configure.ac, NEWS: Update.
4969 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4971 * config/texinfo.tex: Sync from upstream.
4973 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4974 quadrigraph correctly in traces.
4976 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4977 Fix typos.
4979 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4980 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4981 not defined.
4982 * doc/autoconf.texi (Changed Directory Variables): New node,
4983 to document the whole `datarootdir' business a bit better.
4984 * NEWS: Update.
4985 * tests/torture.at (datarootdir workaround): Extend test.
4986 Prompted by report by Alexandre Julliard.
4988 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4990 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4991 when using default mode of IBM C 6 for AIX. Problem and two-line
4992 fix reported by Larry Jones.
4994 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4996 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4997 about literal '${datarootdir}' if a definition is found in the
4998 output file.
5000 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5002 * NEWS: Use "M4" rather than "m4" when appropriate.
5003 Problem reported by Eric Blake.
5004 * doc/autoconf.texi: Likewise.
5005 Use @acronym around BSD, GCC, and GNU when appropriate.
5006 (Why GNU M4): Renamed from "Why GNU m4".
5007 (Redefined M4 Macros): Mention that Posix
5008 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5009 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5010 to int.
5012 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5014 * bin/autom4te.in (handle_output): Do not forbid the empty
5015 pattern.
5016 * tests/tools.at (autoconf: the empty token): New test.
5018 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5020 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5021 calls, so that we do not care whether they are LIFO or FIFO;
5022 in the m4_wrap, do not check which diversion is the topmost
5023 one, just check that the stack is balanced at the end.
5024 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5025 base diversion forever--pop the previous diversion before
5026 opening the new one; consequently, remove the m4_wrap call.
5027 * lib/autotest/general.m4 (AT_INIT): Likewise.
5028 * tests/m4sugar.at: Do not use
5029 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5031 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5032 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5034 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5035 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5036 Rework example of m4wrap token-pasting trouble so that it doesn't
5037 care whether it's LIFO or FIFO.
5038 Fix some "contrary to"s that are awkward in English.
5040 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5042 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5043 to `yes' instead of `int$1_t' if the type is found, for more
5044 consistent configure output (where $1 is the number of bits).
5045 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5046 Suggested by Bruno Haible.
5048 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5049 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5050 with system headers. Report by Bruno Haible.
5052 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5054 * config/config.guess, config/config.sub: Sync from upstream.
5056 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5057 in order to avoid picking up an older installed frozen m4sh.m4f.
5058 Besides an outdated shell startup, this could have been created
5059 by an earlier M4 version with incompatible frozen file format.
5061 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5063 * README: Recommend m4 1.4.4 instead of 1.4.3..
5064 * doc/autoconf.texi: Likewise.
5065 (Special Chars in Names): Say that $(.FOO) is portable, as
5066 suggested by Stepan Kasal.
5067 (Installation Directory Variables, Build Directories):
5068 (Automatic Remaking, Subdirectories, Fortran Compiler):
5069 (Making testsuite Scripts, Defining Directories):
5070 Quote variable usages better.
5071 (Making testsuite Scripts): Add clean-local rule to makefile
5072 snippet, by Eric Blake.
5073 (Installation Directory Variables): Fix table item font.
5074 Reword slightly to clarify. Generalize advice about
5075 not using special characters to include all file-related
5076 vars, not just VPATH.
5077 (Special Chars in Variables): Warn about special characters in
5078 $(srcdir) too.
5079 (Assignments): Clarify default-value example as suggested by
5080 Ralf Wildenhues in
5081 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5082 (Special Shell Variables): Note leading ./ or ../, as suggested
5083 by Eric Blake.
5084 (Limitations of Builtins): Under cd, warn about CDPATH.
5085 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5086 Ralf Wildenhues.
5088 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5090 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5091 `@var', for texi2html.
5092 (Systemology): Some more word wrapping, for DVI output.
5093 (autom4te Invocation): The short option for `--melt' is `-M',
5094 not `-m'.
5096 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5098 * doc/autoconf.texi: More formatting and English tweaks,
5099 many suggested by Ralf Wildenhues.
5100 Reword to avoid "@code{...}'s" and the like, since it's ugly
5101 with Emacs info mode. discontents -> woes.
5102 Put a few "will"s back. time stamp -> timestamp.
5103 side-effect -> side effect.
5105 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5107 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5108 Warn about $@ not persisting. Problem reported by Julien Danjou in
5109 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5110 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5111 Mention other special chars, too.
5113 2006-06-14 Eric Blake <ebb9@byu.net>
5115 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5117 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5119 * doc/autoconf.texi: Some systematic minor improvements, as
5120 follows. Use "makefile" when talking about makefiles
5121 generally (which might be named "makefile" or "Makefile" or even
5122 "foo.mk"), "Makefile" when talking about a specific makefile
5123 called "Makefile". This unclutters the text from weird quotes
5124 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5125 values" rather than "@var{foo}s" and similar constructs containing
5126 "}s". Use "Make rules" rather than "Makefile rules". Minor
5127 English-language improvements. Change the prefix "sub-" to "sub"
5128 and "re-" to "re".
5129 Put blank lines around examples more consistently.
5130 Avoid "rather" and "very" as intensifiers.
5131 Avoid "will" as an auxiliary.
5132 (Limitations of Make): Split this node into....
5133 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5134 (Leading _ in Macro Names, Backslash-Newline-Newline):
5135 (Backslash-Newline Comments, Long Lines in Makefiles):
5136 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5137 (obj/ and Make, make -k Status, VPATH and Make):
5138 (VPATH and Double-colon, $< in Explicit Rules):
5139 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5140 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5141 New nodes, resulting from splitup of Limitations of Make.
5142 All cross-references changed. Raise the top node from
5143 a section to a chapter, and all subnodes accordingly.
5144 Redo the introductory wording to match the new organization.
5145 (Installation Directory Variables): Use an example that is
5146 closer to what Autoconf actually does. Mention that VPATH's
5147 value should not contain metacharacters or white space.
5148 (Fortran Compiler): Fix a VPATH bug in an example.
5149 (Leading _ in Macro Names): Mention that this problem is no longer
5150 of practical concern.
5151 (VPATH and Make): Reword the advice to make it clearer
5152 that Autoconf and Automake support VPATH in non-GNU make, but
5153 many packages have bugs in this area.
5154 ($< in Explicit Rules): Refer to Build Directories rather
5155 than using a (non-VPATH-safe) example.
5156 (Automatic Rule Rewriting): Mention the sort of disaster that
5157 can ensue with Solaris-style rule rewriting with VPATH.
5159 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5161 * doc/install.texi (Compilers and Options): Weaken the
5162 suggestion to use GNU make for VPATH builds.
5164 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5165 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5167 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5168 in regular expression.
5170 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5172 * doc/autoconf.texi (Installation Directory Variables):
5173 Drop extra @samp from `@table @samp' item.
5174 (Limitations of Usual Tools): Comment fix.
5175 Do not nest @samp just to point to other table items.
5176 (Writing testsuite.at) <AT_CHECK>: The second argument to
5177 `@dvar' is already @samp'ed.
5178 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5179 do not use @var in the second argument.
5181 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5183 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5184 $as_shell.exe too. Problem reported by Andreas Buening in
5185 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5187 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5189 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5190 `unused variable' compiler warning, for `-Wall -Werror'.
5191 Reported by Jaap Haitsma in
5192 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5194 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5196 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5197 case the compiler dumps core. Problem reported for
5198 OpenServer 5.0.7 by Tim Rice in
5199 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5200 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5201 Likewise.
5203 2006-06-06 Tim Rice <tim@multitalents.net>.
5205 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5206 "ERROR" only shows up in "make check" output if there is an
5207 error.
5209 2006-06-06 Eric Blake <ebb9@byu.net>
5211 * tests/tools.at (automatically allowed tokens): Fix typo.
5213 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5215 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5217 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5218 typically overflows on x86 CPUs, even though the C standard
5219 requires otherwise.
5221 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5223 * configure.ac (AC_INIT): Bump to 2.59e.
5224 * NEWS: Update.
5226 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5228 Version 2.59d.
5230 * config/texinfo.tex: Sync from upstream.
5232 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5233 seen, invoke libtoolize with `--ltdl' argument.
5234 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5235 * NEWS: Update.
5236 Suggested by Eric Blake.
5238 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5240 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5241 reported by Ralf Wildenhues.
5242 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5244 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5246 * THANKS: Update.
5248 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5250 * doc/autoconf.texi: Modernize some of the references to Solaris.
5252 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5254 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5255 message issued by AC_REQUIRE.
5256 * tests/m4sugar.at: Check m4_require's error message.
5257 * tests/base.at: Check AC_REQUIRE's error message.
5258 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5259 to...
5260 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5261 AT_CHECK_M4.
5262 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5263 `expout' as the last parameter.
5264 * tests/tools.at: Adapt to the above change.
5266 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5268 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5269 information about race-free implementations of mkdir.

5276 * doc/autoconf.texi (autom4te Invocation): Likewise.
5278 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5280 * NEWS: GNU make now recommended for VPATH builds.
5281 Mention that some macros are now documented to be obsolescent.
5282 * doc/autoconf.texi:
5283 Prefer "current" to "modern" to describe
5284 currently-used (albeit perhaps old-fashioned) hosts.
5285 Mention which ancient features no longer need to be worried about.
5286 setgid -> set-group-ID
5287 setuid -> set-user-ID (these are the Posix terms)
5288 Fix some misuses of "only".
5289 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5290 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5291 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5292 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5293 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5294 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5295 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5296 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5297 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5298 Mention that these macros are obsolescent.
5299 (Installation Directory Variables): shall -> should
5300 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5301 Mention that it's now safe to use 3 and 4.
5302 (Limitations of Usual Tools): cp -r is now specified by Posix.
5303 Omit longwinded and obsolescent discussion of cp -f.
5304 Modernize discussion of expr, ls.
5305 (Limitations of Make): Modernize discussion of VPATH builds.
5306 Mention $? as a workaround in some cases.
5307 * doc/install.texi (Basic Installation):
5308 Mention "./configure; make; make install" first. Be more
5309 specific about why this file is generic. Remove unnecessary
5310 parens. Remove misleading "only". Remove obsolete advice
5311 about csh. Don't say "configure" takes awhile; say it
5312 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5313 and CC=c99 rather than CC=c89, as these are blessed by current
5314 Posix. Recommend GNU make if doing a VPATH build.
5316 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5318 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5319 examples involving shell prompts.
5321 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5322 and Paul Eggert <eggert@cs.ucla.edu>
5324 * doc/autoconf.texi (Here-Documents): Add details about the
5325 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5326 use "here-documents" instead of "here documents".
5328 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5330 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5332 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5334 * doc/autoconf.texi (File System Conventions): Warn about ":"
5335 anywhere in directory names.
5337 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5339 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5340 about quoting the case statement, just in case.
5341 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5342 was fixed in ksh93g; reported by Ralf Wildenhues.
5344 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5346 * doc/autoconf.texi (System Services): Do not document
5347 overriding EXEEXT via ac_cv_exeext=ext.
5348 (Particular Programs) <AC_PROG_MKDIR_P>:
5349 Document that ${MKDIR_P} understands --.
5350 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5351 comment.
5353 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5355 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5356 argument with leading hyphen. Problem reported by Paul Eggert.
5358 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5360 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5361 about quoting ac_try: quote all of it, if any of it seems suspicious.
5362 This means we don't have to worry about ${ or sed any more.
5363 Also, double-quote the case statement, to work around misuses via
5364 underquoting as reported by Ralf Wildenhues in
5365 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5366 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5367 undocumented and dangerous macro.
5368 Problem reported by Ralf Wildenhues in
5369 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5371 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5373 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5374 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5375 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5377 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5379 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5380 since evidently some packages rely on the old, broken behavior.
5381 Problem reported by Ralf Wildenhues in
5382 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5383 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5384 pre-2006-05-26 definitions, but leave in the comments that
5385 these macros are dangerous and should not be used.
5386 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5387 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5388 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5389 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5390 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5392 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5394 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5395 the use of 'tr', since this is our only use of 'tr'.
5397 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5398 and Paul Eggert <eggert@cs.ucla.edu>
5400 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5401 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5403 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5405 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5406 the output file in the `${datarootdir}' test.
5408 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5409 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5411 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5412 mention of `datarootdir' in the input file(s), but literal
5413 `${datarootdir}' in the output file, and we haven't warned yet,
5414 then warn as well: the user may have (erroneously) used
5415 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5416 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5417 * tests/torture.at (datarootdir workaround): Extend this test.
5418 * NEWS: Update.
5420 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5421 and Paul Eggert <eggert@cs.ucla.edu>
5423 * doc/autoconf.texi (autoheader Invocation): The first argument to
5424 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5425 alternatives and clear up the language a bit.
5427 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5429 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5430 ac_config_guess, ac_config_sub, ac_configure.
5431 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5432 Fix typo that prevented an unnecessary space from being removed.
5433 Problems reported by Ralf Wildenhues in:
5434 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5436 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5438 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5439 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5440 Don't use the term "thread-safe" to talk about mkdir race
5441 conditions, since the problem is more a process than a thread
5442 issue. Problem reported by Stepan Kasal in:
5443 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5444 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5445 the test for 'install' more closely. Look at MKDIR_P first.
5446 Look in the PATH, and at /opt/sfw/bin.
5447 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5448 Don't bother to try mkdir -p, since we already check mkdir --version;
5449 just look at the version number. (There's no easy way to check
5450 for race-free implementations.)
5451 * tests/tools.at (autoconf: subdirectories): Adjust to above
5452 changes, since MKDIR_P now might end in "/mkdir -p".
5454 * doc/autoconf.texi (autoheader Invocation): Mention that the
5455 first arg of AC_DEFINE_UNQUOTED must be a literal.
5456 Problem reported by Ben Pfaff in
5457 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5459 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5460 * doc/autoconf.texi (Special Chars in Variables): New section.
5461 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5462 (Installation Directory Variables): Quote $(datadir) better.
5463 (Limitations of Builtins): Describe some of eval's trickiness.
5465 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5466 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5467 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5468 in front of every arg, not just trailing args. Quote apostrophes.
5469 (_AC_EVAL_ECHO): New macro.
5470 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5471 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5472 removed.
5473 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5474 exposed by quoting of eval argument. Put the command on line line
5475 so it logs better.
5476 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5477 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5478 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5479 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5480 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5481 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5482 Use eval more safely.
5483 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5484 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5485 to be replaced.
5486 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5487 lines, exposed by quoting of eval argument.
5489 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5490 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5492 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5493 initialization of `ac_cv_exeext', do not override it if it was
5494 already set, unless it was set to `no', for compatibility with
5495 Autoconf-2.13, and comment this.
5496 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5497 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5498 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5499 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5500 Document that this test may be overridden by setting
5501 `ac_cv_exeext'.
5503 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5505 Revert these two patches:
5507 2006-04-06 Eric Blake <ebb9@byu.net>
5508 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5509 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5510 2006-04-01.
5512 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5513 Clean up _AC_COMPILER_EXEEXT* macros.
5514 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5515 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5516 ac_file to the name of the default output file and call
5517 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5518 initial `rm' of the candidate files...
5519 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5520 the same list in subsequent `rm' calls, and for the temporary
5521 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5522 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5523 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5524 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5525 no longer needed) by libtool. Make it a cache check.
5526 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5527 copied here by mistake.
5528 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5529 _AC_COMPILER_EXEEXT.
5530 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5531 _AC_COMPILER_OBJEXT directly.
5532 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5534 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5536 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5537 Fix description of how the buggy `sed' works.
5539 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5541 Sync from Automake:
5543 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5544 ENOLCK. Only mention `make -j' when applicable. Only raise
5545 fatal errors when `make -j' is involved. Improve error message.
5547 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5549 * doc/autoconf.texi (Here-Documents): We now know more about
5550 the variable expansion in here documents bug.
5551 Thanks to Tim Rice and Stepan Kasal.
5553 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5554 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5556 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5558 * tests/autotest.at (Multiline command from M4 expansion):
5559 No failure to be expected if the shell quotes newlines in
5560 commands in the `set -x' output. Report by Tim Rice.
5561 * THANKS: Update.
5563 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5565 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5566 expansion in the here-documents used by config.status, as that
5567 runs afoul of the Korn shell version M-12/28/93d bug described in
5568 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5569 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5570 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5572 2006-05-23 Jim Meyering <jim@meyering.net>
5574 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5575 Fix typo introduced with 2006-04-02 change. It reversed the sense
5576 of the test.
5578 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5580 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5581 ac_dB slightly, to save bytes in the script.
5582 Max out at 50 lines, rather than 96; this is more likely
5583 (though not guaranteed) to avoid obscure 'sed' failures.
5585 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5587 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5588 `tr -d -' as bad option argument. Work around this by deleting
5589 an unrelated character.
5590 Report by Tim Rice <tim@multitalents.net>.
5592 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5593 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5594 Stepan Kasal <kasal@ucw.cz>
5596 * doc/autoconf.texi (Particular Programs): Do not promise that
5597 we always prefer the GNU version of the program, and that we
5598 search according to PATH; both rules can have exceptions.
5599 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5600 AC_PROG_SED. Move descriptions of limitations
5601 to the Limitations of Usual Tools section.
5602 (Limitations of Usual Tools) <sed>: Mention script length
5603 limitations with Solaris /usr/ucb/sed.
5604 <grep>: Fix wording for empty alternative. Mention that -c and
5605 -l should not be combined, and that -E and -F should not be
5606 combined.
5608 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5609 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5611 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5612 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5614 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5616 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5617 AC_DEFINE is now passed to m4_pattern_allow.
5618 * NEWS: Mention that; likewise for AC_SUBST.
5619 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5620 the parameter to m4_pattern_allow.
5621 * tests/tools.at: Add a check for that.
5623 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5625 * lib/autoconf/status.m4: Fix typos.
5627 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5629 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5630 only the files that this macro generates.
5632 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5634 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5635 the HP-UX sed limitation of 99 commands, labels do not count.
5636 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5637 in the comment.
5638 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5640 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5642 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5643 Import the following fix from coreutils:
5645 2006-01-13 Jim Meyering <jim@meyering.net>
5647 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5648 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5649 not double-quote uses of that variable, to accommodate the rare
5650 case in which getmntent is available in none of the libraries
5651 checked. This happens at least on FreeBSD 5.0.
5653 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5655 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5656 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5657 some other programs unwisely rely on these undocumented vars.
5658 But put in warning comments about them.
5659 Problem reported by Ralf Wildenhues in
5660 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5661 * NEWS: Document that these variables are intended to go away.
5663 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5665 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5666 and set the language to C++ (analogous to the equivalent Fortran
5667 tests).
5669 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5670 * doc/autoconf.texi (C++ Compiler): Document it.
5671 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5672 * NEWS: Update.
5674 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5676 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5677 that caused config.status to generate 100-command sed scripts; the
5678 portable limit is 99.
5680 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5682 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5683 variable `ac_d' instead of `d' to avoid infringing namespace.
5684 Report by Ralf Menzel.
5686 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5688 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5689 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5690 * tests/tools.at (autoconf: subdirectories): New test, taken from
5691 the corresponding problem report by Ralf Wildenhues in:
5692 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5694 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5695 Quote some uses of shell variables if they might suffer unexpected
5696 globbing. This doesn't fix all instances of quoting problems that
5697 I found, just the easy ones that look safe.
5698 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5699 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5700 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5701 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5702 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5703 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5704 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5705 Likewise.
5706 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5707 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5709 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5711 * bin/autoreconf.in ($help): Reword according to the manual.
5712 Suggested by Olly Betts.
5714 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5715 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5717 * bin/autoreconf.in: Pass the directory argument to
5718 `require_configure_ac'. Fix comment.
5719 * tests/torture.at (Configuring subdirectories): Expose this.
5720 Reported by Olly Betts.
5722 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5724 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5725 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5726 Automake as follows:
5728 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5729 `$configure_in' instead of `configure.in', to preserve
5730 directory component.
5732 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5734 * config/config.guess, config/config.sub, config/texinfo.tex,
5735 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5737 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5739 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5740 test for C99 conformance; (bool) 0.5 is an integer constant
5741 expression, but (bool) -0.5 is not. Problem reported by Fedor
5742 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5744 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5746 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5747 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5748 Warn about obsolete install-sh files. Remove stray sentence
5749 fragment and fix cross reference.
5750 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5751 install -d; this undoes the 2006-05-10 change.
5752 (MKDIR_P): Mark with AN_MAKEVAR.
5753 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5754 that we don't require $INSTALL to be thread-safe. Move comments
5755 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5756 of AC_PROG_INSTALL. Output a message saying that we're checking
5757 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5758 MKDIR_P instead of AC_SUBST.
5759 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5760 Special magic for MKDIR_P, too.
5761 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5762 a dnl.
5763 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5765 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5767 Sync from Automake, as follows:
5769 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5770 * config/install-sh: Initialize IFS, so field splitting isn't
5771 turned off later.
5772 * config/mkinstalldirs: Likewise.
5773 * config/missing: Remove superfluous quotes. Replace all uses of
5774 `[' by `test', for consistency, and for..
5775 * config/missing (sed_minuso, sed_output): New variables.
5776 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5777 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5778 Fixes `missing' to detect `--output' for help2man. Fixes
5779 PR automake/483. Report by Dennis J. Linse.
5780 (autom4te): Document in `missing --help'.
5782 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5784 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5785 * config/install-sh: Don't use 'path' to talk about file names,
5786 as per GNU coding standards. Close a race condition reported by Ralf
5787 Wildenhues and Stepan Kasal. There is still a race condition
5788 on hosts that predate Posix 1003.1-1992, but we can't help this.
5789 Don't mishandle weird characters like space on pre-Posix hosts.
5790 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5791 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5792 AC_PROG_MKDIR_P from AS_MKDIR_P.
5793 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5794 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5795 earlier editions are not (including Automake 1.8.3).
5796 Do not suggest mkinstalldirs for thread-safety.
5797 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5798 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5799 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5800 presence of special characters and race conditions.
5801 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5802 in Autoconf's name space.
5804 2006-05-10 Bruno Haible <bruno@clisp.org>
5805 and Paul Eggert <eggert@cs.ucla.edu>
5807 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5808 from Automake with minor changes.
5809 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5811 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5813 * config/install-sh: Update to Automake CVS version, as follows:
5814 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5815 * lib/install-sh: Simplify the expr implementation of dirname.
5816 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5817 * lib/install-sh: Handle --, and diagnose unknown options.
5819 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5821 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5822 `./autom4te' to create `./testsuite', since the `all' target
5823 will ensure its presence, but `installcheck' should not create
5824 the uninstalled wrappers.
5826 * tests/torture.at (Unusual Automake input files): Skip if we
5827 detect automake < 1.8.
5829 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5831 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5832 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5833 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5834 * NEWS: Update.
5836 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5838 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5839 munge (multiple) white space and other oddities.
5840 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5841 single quotes in variable assignment.
5842 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5843 and similar failures by adding multiple spaces, tabs, and other
5844 special characters.
5845 Report and different test suggested by Francesco Romani
5846 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5848 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5849 single quotes, we only need to search for single quotes; this
5850 both simplifies the search pattern, and makes us less
5851 susceptible to `echo' variations for arguments not containing
5852 single quotes.
5853 (_AC_ARG_VAR_VALIDATE): Likewise.
5855 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5857 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5858 `$*' and IFS concatenation issue with traditional shells and
5859 bash-2.04. Report by Seanster@Seanster.com.
5861 2006-05-03 Bruno Haible <bruno@clisp.org>
5863 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5864 precisely which Mac OS X versions have the od problem.
5866 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5868 * doc/autoconf.texi: Use @option systematically.
5870 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5871 and Bruno Haible <bruno@clisp.org>
5873 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5874 about 'od'.
5875 (Integer Overflow): Mention the special case of integer division
5876 overflow.
5878 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5880 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5881 traditional shells like the Solaris one that do not use the
5882 first IFS character for assembling `$*'.
5883 Prompted by a related report from autoconf_bug@nro.ca.
5885 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5886 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5888 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5889 Mention more problems with the -e option.
5891 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5893 * NEWS: Typo.
5894 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5896 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5897 in URLs to improve DVI formatted output (requires texinfo 4.6).
5898 (System Services, Systemology, Shellology): Likewise.
5899 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5900 output.
5902 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5903 continuous text.
5904 (Runtime): Fix macro argument names to match description:
5905 `action-if-found' -> `action-if-true' and similarly.
5906 (Obsolete Macros): Likewise.
5907 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5908 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5909 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5911 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5913 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5915 * ChangeLog: Typo.
5916 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5917 DVI output.
5919 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5924 * tests/local.at: Likewise.
5926 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5928 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5929 (Integer Overflow, Null Pointers, Buffer Overruns):
5930 (Floating Point Portability, Exiting Portably): New sections.
5931 (Writing Test Programs): Fix some langauge. Recommend exiting
5932 with status 1, not merely nonzero. Clarify exit declaration.
5933 (Run Time): Move C exit status stuff to new Exiting Portably section.
5934 (Systemology): Mention Posix and levenez. Update v7 reference.
5935 (Portable Shell): Mention the Posix shell.
5937 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5939 * bin/autoconf.as (me): Replace by as_me.
5941 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5943 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5944 since as_me isn't set yet.
5946 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5948 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5949 a few minor bugs in this area.
5951 * doc/autoconf.texi (Programming in M4sh): Comment out the
5952 documentation of AS_BASENAME, for now.
5953 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5954 (Limitations of Builtins) <basename>: Do not refer to
5955 AS_BASENAME.
5956 * bin/autoconf.as (me): Don't use AS_BASENAME.
5957 (dir): Remove the unused variable.
5958 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5959 AS_DETECT_REQUIRED. All uses changed.

5961 All uses changed.
5962 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

5965 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5966 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5967 (_AS_DIRNAME_PREPARE): Likewise.
5968 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5969 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5970 (AS_DIRNAME): Use "dirname --".
5972 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5974 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5975 of "run time" and "run-time" changed to "runtime", for consistency.

5982 with more accuracy and detail.
5984 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5986 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5987 Archive is not officially `GNU' any more. Update URL.
5988 (Defining Directories): Likewise
5989 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5991 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5993 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5994 newline from the `trap' code to finish `config.log'; the NetBSD
5995 /bin/sh resets the exit status after an empty command, as
5996 documented in doc/autoconf.texi.
5997 Reported by Dalibor Topic <robilad@kaffe.org>.
5999 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6001 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6002 Suggested by Bruno Haible.
6004 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6006 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6007 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6008 Instead, just list the shells that we know work.
6009 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6010 changed. Be more cautious about the _cv_ variable.
6011 * tests/tools.at (Syntax of the shell scripts): Check the
6012 _cv_ variable once, at first, to avoid an internal autoconf error
6013 when sh -n does not work.
6015 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6017 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6019 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6021 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6022 use ">&-" since we're only 99.999% sure that this is portable,
6023 and since the MinGW bug is fixed in a different way.
6024 * lib/autotest/general.m4 (AT_INIT): Likewise.
6026 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6028 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6029 before opening config.log, to avoid hitting a bug on MinGW.
6031 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6033 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6034 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6035 This works around a MinGW bug reported by Eric Paire.
6036 Make sure that all writes to the log file append to it,
6037 rather than possibly losing data.
6038 * lib/autotest/general.m4 (AT_INIT): Likewise.
6040 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6042 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6043 description.
6045 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6047 * NEWS: Update.
6049 * configure.ac (AC_INIT): Bump to 2.59d.
6051 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6053 Version 2.59c.
6055 * Makefile.maint (news-date-check): Do not require a leading `*'
6056 before the release date in NEWS.
6058 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6059 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6061 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6062 the instantiated file do not contain the string 'datarootdir'
6063 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6064 @mandir@, replace the reference '${datarootdir}' by the value.
6065 * tests/torture.at (datarootdir workaround): New test.
6066 * NEWS: Advertise this temporary fixup.
6067 Based on a patch by Bruno Haible, reported and analyzed by
6068 Paul Eggert and Noah Misch.
6070 2006-04-12 Eric Blake <ebb9@byu.net>
6072 * tests/autotest.at (Debugging a failed test): Fix comment.
6074 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6076 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6077 all the changes since 2006-04-07.
6079 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6081 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6082 succeeded, but `ln -s file dir' failed, take care to remove the
6083 leftover target before the next test, to prevent its spurious
6084 failure; also make sure `ln file dir' works before selecting it.
6085 Thanks to Keith Marshall for pointing this out.
6086 * THANKS: Update.
6088 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6089 assignments in `at_debug_args', so that we put them correctly
6090 in the `run' script.
6091 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6092 Reported by Eric Blake.
6094 2006-04-11 Eric Blake <ebb9@byu.net>
6096 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6097 top-level tests after micro-suite has been run. Used in...
6098 (Debugging a successful test, Debugging script and environment),
6099 (Debugging a failed test): ...these new tests. The first of these
6100 is fixed by...
6101 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6102 macro, split out from...
6103 (AT_INIT): ...here, so that using -d also generates a run script.
6104 Document that -d inhibits top-level logging.
6105 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6106 inhibits top-level logging; debug scripts are created.
6108 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6109 check.
6110 * tests/autotest.at (Empty test, Empty check): New test to check it.
6112 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6113 from gcc.
6115 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6117 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6118 the files if a problem appears. Make the empty *.at files
6119 read-only, too. Proposed by Ralf Wildenhues.
6121 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6123 * config/Makefile.am: Add comment to force updated Makefile.in.
6125 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6126 space only patch to this file, this patch causes the Makefile.in
6127 files that include freeze.mk to be updated, and thus have a
6128 newer time stamp again, which in turn makes a pristine CVS
6129 checkout have correct time stamps.
6131 * Makefile.maint (cvs-sv): New macro, to be used..
6132 (config.guess-url_prefix, config.sub-url_prefix)
6133 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6134 point to CVS text checkout of Gnulib files.
6135 (copyright-check): Bump current year.
6136 (announcement): Do not hard-wire `./announce-gen'.
6137 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6138 correctly.
6139 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6140 `chmod +x'.
6141 (wget_files): Update config.guess, config.sub, texinfo.tex by
6142 `wget-update', now that their URLs work again.
6144 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6146 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6147 Problem noted by Paul D. Smith.
6149 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6151 * doc/autoconf.texi: Remove unused words from word list.
6152 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6153 .x-sc_trailing_space: New files.
6155 * doc/standards.texi: Sync from gnulib.
6157 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6158 `LIBOBJDIR' as experimental.
6160 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6161 with a target directory; it's internally implemented as `cp'
6162 anyway, but since Autoconf advertises the possibility to use
6163 a target directory when LN_S is `ln -s', we need to find out.
6164 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6165 analyzed by Keith Marshall <keith.marshall@total.com>.
6167 * THANKS: Update.
6169 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6171 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6172 confdefs.h as-is. In general, if it has backslash-newline or the
6173 like, then it doesn't work either to sort or to remove empty
6174 lines.
6176 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6178 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6180 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6182 * lib/autom4te.in (Automake-preselections): Preselect
6183 _AM_SUBST_NOTMAKE.
6185 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6187 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6188 apostrophe within a single-quoted string, as this is the usual
6189 tradition and is easier to read than '"'"'. Don't rely on the
6190 shell treating "$/" like '$/'. Use a more-consistent indenting
6191 style for the trap.
6193 2006-04-09 Eric Blake <ebb9@byu.net>
6195 * tests/autotest.at (Backquote command substitution),
6196 (Multiline backquote command substitution): Remove mistaken
6197 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6198 applied...
6199 (Parenthetical command substitution, Multiline parenthetical
6200 command substitution): here.
6202 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6204 Import macros from gnulib (often changing their name).
6206 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

6218 (Pointers): Add Gnulib URL.
6219 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6220 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6221 Gnulib section.
6222 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6223 suggest a #define rather than a typedef for _Bool, and mention
6224 Gnulib rather than trying to substitute stdbool code.
6225 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6226 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6227 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

6230 headers too.
6231 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6232 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6233 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6234 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6235 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6236 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6237 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6238 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6239 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6240 (Coding Style). Don't mention m4_expand_once.
6241 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6242 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6243 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6244 (AC_CHECK_FUNCS): Use it.

6248 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6249 (AC_HEADER_ASSERT): New macro.
6250 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6251 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6252 Catch a bug in an HP-UX C compiler.
6253 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6254 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6255 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
6256 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
6257 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
6258 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6259 New macros.
6261 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6262 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6264 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6266 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6267 of the warning introduced by the 2001-08-28 change.
6269 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6270 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6272 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6273 variables shall be overriden by the cache.
6274 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6275 that contains braces.
6277 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6279 Revert the patch from 2006-04-01 and only improve
6280 _AS_DETECT_BETTER_SHELL:
6282 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6283 skip nonexistent directories.
6284 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6285 only shell candidates which exist.
6286 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6287 * lib/autotest/general.m4 (AT_INIT): No need to give three
6288 parameters to _AS_PATH_WALK.
6290 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6291 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6293 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6294 distinguish m4sugar macros.
6295 * tests/tools.at (autoupdating with aclocal and m4_include):
6296 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6297 test case by Noah Misch <noah@cs.caltech.edu>.
6299 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6301 Revert my change from 2006-03-17, in other words:
6302 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6303 and DUALCASE=1.
6304 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6305 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6306 it is set.
6308 2006-04-07 Eric Blake <ebb9@byu.net>
6310 * doc/autoconf.texi (Programming in M4sh): Document that
6311 AS_MKDIR_P exits the script on failure.
6312 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6314 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6316 * config/elisp-comp, config/install-sh, config/mdate-sh,
6317 config/missing, config/mkinstalldirs: Sync from Automake.
6319 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6320 from Automake.
6322 * doc/make-stds.texi: Sync from gnulib.
6324 2006-04-06 Eric Blake <ebb9@byu.net>
6326 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6327 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6328 2006-04-01.
6330 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6331 Eric Blake <ebb9@byu.net>,
6332 Paul Eggert <eggert@cs.ucla.edu>,
6333 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6335 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6336 whether `set' quotes correctly: redirect stderr of the tested
6337 `set', and use a subshell, for Ultrix; use `sed' instead of
6338 `grep' for zsh `set' which may write binary output; match only
6339 at the beginning of a line, to avoid false positives.
6340 In order to avoid false positives by unrelated variables with
6341 multiline content, put the dump algorithm in a subshell and
6342 unset all variables containing newlines (except some which are
6343 special to the shell). Warn about cache variables that are
6344 unset.
6346 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6348 * config/config.guess, config/config.sub, config/texinfo.tex:
6349 Sync from upstream.
6351 * tests/mktests.sh: Reword comments.
6353 * tests/mktests.sh: Only skip internal macros starting with
6354 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6355 Update exclusion lists for the test suite to this end:
6356 (AC_ARG_VAR): Do test this now.
6357 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6358 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6359 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6360 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6362 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6363 shell issue with double-quoted command substitutions of native
6364 commands.
6365 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6366 Marshall.
6368 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
6369 no file matches the glob, discard the warning, set `nullglob'.
6370 (syntax-check): Likewise.
6371 (sc_cast_of_x_alloc_return_value): Likewise.
6372 (sc_cast_of_alloca_return_value, sc_error_exit_success)
6373 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
6374 (m4-check): Likewise.
6375 (sc_system_h_headers): Do not print rule on execution.
6376 (sc_tight_scope): Do not fail for non-existing `src' directory.
6377 (sc_changelog): Skip the Copyright footer.
6378 * lib/autoconf/lang.m4: Remove trailing space.
6380 * lib/autoconf/status.m4: More replacements to
6381 <tab><space> where this makes sense.
6383 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6385 * tests/Makefile.am (maintainer-check-posix):
6386 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6388 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6389 ac_config_<foo>s again, sometimes normalized, sometimes not.
6390 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6391 (AC_CONFIG_COMMANDS): Do not do so here.
6392 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6393 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6394 2005-07-25 rewrite. Noticed by Noah Misch.
6396 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6397 _AC_PRESERVE_HELP_ORDER, ...
6398 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6400 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6401 inside m4_expand_once; it is redundant.
6403 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6404 for --help from Cygnus `configure.'
6406 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6408 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6409 on a patch proposed by Ralf Wildenhues.
6411 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6413 * lib/autoconf/status.m4: Replace <space>''<tab> with
6414 <tab><space> where this makes sense.
6416 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6417 Noah Misch <noah@cs.caltech.edu>
6419 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6420 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6421 * doc/autoconf.texi (Help Formatting): New node.
6422 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6424 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6426 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6427 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6428 lib/autoconf/types.m4, lib/autotest/general.m4,
6429 tests/mktests.sh, tests/torture.at: White space cleanup:
6430 remove some SPACE before TAB, or add quoting ('' or @&t@).
6432 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6434 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6436 2006-04-05 Eric Blake <ebb9@byu.net>
6438 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6439 empty test suite works.
6440 * tests/autotest.at (Empty test suite): Remove xfail.
6442 2006-04-05 Noah Misch <noah@cs.caltech.edu>
6444 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
6445 TAGS to ac_config_<foo>s.
6446 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6447 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6448 normalizing it, consistent it with previous releases.
6449 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6451 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6453 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6454 Use simplified args that Eric Blake originally suggested.
6456 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6458 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6459 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6460 Use 'comm' rather than N instances of grep; this also fixes a bug
6461 whereby substrings were incorrectly matched, causing us to not
6462 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6463 (exclude_list): Exclude empty macros.

6549 ac_file to the name of the default output file and call
6550 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6551 initial `rm' of the candidate files...
6552 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6553 the same list in subsequent `rm' calls, and for the temporary
6554 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6555 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6556 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6557 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

6637 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6638 switch all of them on and of when necessary. Fixes the bug when
6639 m4sugar macros (e.g., m4_define) were expanded after the first
6640 automatic update (e.g., after AC_PREREQ or AC_INIT).
6642 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6844 example. Do not emphasize `$%', it is hardly new and special.
6845 Reported by Edouard Bechetoille <ebecheto@ens-lyon.fr>.

6875 the obsolescent AC_HEADER_STDC.
6876 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

6894 HP-UX sed is 99 commands, not 100.
6895 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
6896 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
6897 newline for portability.
6898 * tests/torture.at (Torturing config.status): Also test 100

7392 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7394 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7395 calls, so that the final expansion of this macro is shorter.
7396 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7397 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7398 the cleanup there. Use AS_VAR_* macros, to be more general.
7399 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7401 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7403 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7425 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7426 "if $undefined_var;" succeeds with my shell.
7428 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7429 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7430 but change the m4_divert_text to m4_divert_once.
7432 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7434 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7435 Work around bug in Solaris /usr/xpg4/bin/awk.
7436 The bug is present in at least Solaris 8 through 10.
7438 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7440 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7441 some evil values and relying on the fact that $* concatenates the
7442 parameters by the first character from IFS.
7444 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7445 Stepan Kasal <kasal@ucw.cz>

7449 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7450 Update limitations about when to call AC_CONFIG_HEADERS.
7451 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7452 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7453 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7454 ``Configuration Actions''; fix their index entries.
7456 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7457 options correctly. Process N-M as M-N if M is smaller than N.
7458 Process ranges correctly so that N-N will run only N.
7459 Sort and uniquify the tests that will be run. If there is more
7460 than one test, reinsert the banners for the tests.

7466 before passing the macro name to AH_TEMPLATE.

7491 When building in place, set srcdir="."; suggested by Tim Van Holder.
7493 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize

7496 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

7513 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7515 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7516 was pushdef'ed twice while popped only once. Push it only once.
7517 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7519 2005-07-26 Stepan Kasal <kasal@ucw.cz>

7528 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7529 "<tab>" in comment, so that the point is understandable.
7531 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7533 Rewrite substantial part of lib/autoconf/status.m4.
7534 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7535 and CONFIG_COMMANDS are not processed in four separate loops.
7536 Instead, there is one main loop. This alows that the common code
7537 is expanded only once, thus config.status (and configure) is smaller.
7539 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7540 the AC_LIST_FILES and cousins macros are no longer used.
7542 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7543 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7544 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7545 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7546 contain the initialization, nor the for loop, nor the associated
7547 commands; all these go to ...
7548 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7549 _AC_OUTPUT_CONFIG_STATUS.
7550 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7551 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7552 (_AC_OUTPUT_FILE): The creation of the sed script ...
7553 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7554 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7555 _AC_OUTPUT_MAIN_LOOP.
7556 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7557 _AC_CONFIG_COMMANDS): Use ...
7558 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7559 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7560 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7561 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7562 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7563 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7564 ... new macros.
7565 (_AC_CONFIG_UNIQUE): Update.
7566 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7567 Replaced by this ...
7568 (_AC_LIST_TAGS): ... new common macro.
7569 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7570 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7571 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7572 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7573 this didn't belong to the `config commands' section.
7574 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7575 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7576 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7577 to the `config commands' section either.
7578 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7579 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7581 ... and many changes to the comments nearby.
7583 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7584 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7585 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7586 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7587 (#define header templates): The comment at the top of the generated
7588 header now includes the name(s) of the source file(s).
7590 Several unrelated small changes:
7592 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7593 parameter to AC_DIAGNOSE.
7594 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7595 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7596 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7597 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7598 with AU::AC_OUTPUT.
7599 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7600 in AC_OUTPUT doesn't double-quote it either.
7601 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7602 parameters.
7604 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7606 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7607 versions of Portland Group compiler produce single- and double-quoted
7608 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7609 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7611 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7613 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7614 This is a corrected version of yesterday's patch.
7616 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7618 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7619 path, too; insert a "===" to emphasize the line.
7621 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7622 ac_cv_build_alias to ac_build_alias.
7623 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7625 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7626 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7627 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7628 (AC_ARG_VAR): ... here.
7629 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7630 target_alias.
7632 Keep a list of all precious variables and process them with one simple
7633 for loop, instead of expanding all commands, or, OTOH, complicated
7634 processing of output of "set".
7635 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7636 variable names in new macro...
7637 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7638 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7639 a loop to assign all ac_env_* and ac_cv_env_* variables.
7640 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7641 to INIT_PREPARE.
7642 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7643 its value to shell variable ac_precious_vars and call
7644 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7645 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7646 _AC_ARG_VAR_VALIDATE.
7648 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7649 and the AC_SUBSTs ...
7650 (AC_INIT): ... here.
7652 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
7653 the ac_subst_files section in config.log.
7655 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
7657 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

7666 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7667 They are generated by the Tru64 v5.1B shell.
7669 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7671 Fix my changes from 2005-07-01; reported by Noah Misch.
7672 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7673 description, the macro now accepts only a single tag.
7674 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7676 Fix cases when the varsions of Autoconf and Autotest don't match.
7677 Reported by Noah Misch.
7678 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7679 at_top_builddir, for compatibility with older autotest.
7680 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7681 is not set, use at_top_builddir, for compatibility with older
7682 versions of autoconf.
7684 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7686 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7687 Problem reported by Patrick Welche.
7689 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7691 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7692 sed substitution command, so that we allow | in program prefixes
7693 and program suffixes. (& is a problem anyway; we're not fixing
7694 that here.)
7695 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7696 configure_input, top_builddir, srcdir, etc.
7697 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7698 PATH_SEPARATOR in AUTOTEST_PATH.
7700 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7702 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7703 for loop over config.site files using `set', to allow
7704 directory names containing IFS characters.
7706 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7708 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7709 directories with weird names. Apparently some people like living
7710 on the edge. However, improve the test that "pwd" actually does
7711 report a name for the working directory.
7712 * NEWS: Remove the claim that we test for funny chars in dir names.
7714 2005-07-01 Stepan Kasal <kasal@ucw.cz>

7730 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7731 document to output the default config_* lists to config.status.
7732 Don't recognize option --file, if the functionality is not there.
7733 Likewise for --header; moreover, recognize --he and --h as shortcuts
7734 for --help in that case.
7736 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7737 matches the order of execution. No code changed.

7758 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
7759 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7760 (AC_SUBST): Call it.
7761 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7762 the directory specific variables; but don't call it for configure_input.
7764 2005-06-28 Derek Price <derek@ximbiot.com>
7766 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7767 addition.
7769 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7771 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7772 directory have inherent problems with special characters like spaces,
7773 due to limitations in Make syntax. Problem reported by Alexandre
7774 Duret-Lutz.
7775 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7788 from Justace Clutter.
7789 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7790 variable into diagnostic. Make the diagnostic an error, not a warning,
7791 because we really don't support spaces and suchlike in dir names.
7792 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7793 Don't worry about backslashes in srcdir; it can't happen now.

7795 Simplify ac_optarg handling.
7796 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

7804 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
7806 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7807 that '\|' is not allowed in BREs; recommend using newline separated
7808 list of patterns instead of multiple -e options.
7810 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
7812 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

7818 2005-06-21 Stepan Kasal <kasal@ucw.cz>
7820 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7821 b, t, r, w commands require single space, while : cannot have any.
7822 (Special Shell Variables): Fix sed code this in the example.
7823 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7824 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7826 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7827 expand to the empty list. Don't use two pairs of m4_changequote,
7828 it's not necessary.
7830 2005-06-20 Derek Price <derek@ximbiot.com>
7832 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7834 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7836 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7837 * doc/autoconf.texi:
7838 Don't mention Solaris versions so much, if a
7839 problem is common to all extant versions of Solaris. Say "SunOS
7840 4" instead of "SunOS" for SunOS 4.
7841 (awk): Mention more of the limitations of traditional Awk.
7842 (cat): Don't talk about cat -v.
7844 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
7846 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
7847 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
7848 but the implementation is entirely different and is designed
7849 to be compatible with glibc strverscmp.
7850 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7852 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7853 on Mac OS X 10.4 reported by Peter O'Gorman in:
7854 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
7855 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
7856 Use shell builtins rather than 'expr', to work around expr bug.
7858 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7860 * doc/autoconf.texi: "filesystem" -> "file system".
7861 "behaviour" -> "behavior".
7862 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
7863 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7864 as per POSIX.
7865 * lib/m4sugar/m4sh.m4: Likewise.
7866 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
7867 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7869 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7870 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7871 to update the man page. That way, we don't have to check in new
7872 man pages every month.
7874 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7875 quotes and backslashes. Patch from Derek Price.

7880 AS_TR_SH.
7882 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7884 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7885 -u, since it outputs chatter if the input files are the same.
7886 Problem reported by Ralf Menzel.
7888 2005-06-08 Derek Price <derek@ximbiot.com>
7890 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7891 renaming them since they are about to be redefined anyhow.
7893 2005-06-08 Derek Price <derek@ximbiot.com>
7895 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7896 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7897 Move m4_undefine to alphabetical order.
7899 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7901 * README: Recommend GNU M4 1.4.3 or later.
7902 * doc/autoconf.texi (Introduction): Likewise.
7903 Reword to avoid some formatting glitches.
7904 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7905 Clarify explanation of HP compiler bug.
7906 Redo example output tp match current CVS snapshot.
7907 Use @example.org in email addresses when the examples
7908 might get inadvertently cut-and-pasted into user code.
7909 Remove example of autom4te usage that doesn't seem to work now.
7910 Use modern AC_INIT (except when the example is meant to be
7911 shown with Autoconf 2.13).
7912 Update ksh info for Solaris 9 and later.
7913 KB -> kB.
7914 Modernize description of Automake versions a bit.
7915 Don't claim a future version of Autoconf is near.
7916 * doc/install.texi: Reword to avoid some formatting glitches.
7918 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7920 * doc/autoconf.texi: Add [] to examples, so that the manual
7921 follows its own advice about quoting better.
7922 Reword to avoid some formatting glitches.
7923 * doc/installt.exi: Reword to avoid some formatting glitches.
7925 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7926 Tru64 ksh pattern matching bug. Reported against Libtool by
7927 Albert Chin <libtool@mlists.thewrittenword.com> and
7928 Nicolas Joly <njoly@pasteur.fr>.
7930 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7932 m4_cdr of one-member list was [[]] (one-member list containing an
7933 empty string) instead of [] (an empty list. Callers were skewed to
7934 match this misbehaviour. As a consequence of this:
7935 - m4_foreach([x], [], [foo]) expanded to `foo', while
7936 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7937 This bug has been fixed:
7939 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7940 expand to an empty string; print error msg if called without
7941 an argument list.
7942 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7943 misbehaviour; handle [] and [[]] correctly.
7945 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7947 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7948 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7949 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7951 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7953 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7954 swallow records with more than 99 fields.
7955 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7956 parse the long line.
7958 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7960 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7961 swallow literals longer than 399. Reported by Ralf Wildenhues.
7962 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7963 to workaround this limitation.
7965 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7967 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7968 to gfortran, and make these the first two compiler names
7969 checked (following the general autoconf preference for gcc).
7971 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7973 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7974 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7975 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7977 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7979 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7980 expression of unbounded size when processing the --list
7981 option. This runs afoul of a limit of 399 bytes per regular
7982 expression on AIX. Problem reported by Ralf Wildenhues.
7984 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7986 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7987 * doc/autoconf.texi (Particular Headers): Reword example
7988 for multiline stdbool replacement.
7989 (Setting Output Variables): Reword text a bit. Don't
7990 give all the details about |#_!!_#|.
7991 Reword description of line replacement.
7993 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7995 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7996 now contain newlines, and substituted files must be referenced on
7997 a line alone; the sed scripts to substitute them are now very
7998 different.
7999 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8000 commands can be put in a sed script portably.
8001 * doc/autoconf.texi (Setting Output Variables): Document above
8002 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8003 use of multiline substitution.
8004 * tests/torture.at: No longer expect substitution of newline to fail.
8006 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>

8009 From Ralf Menzel (trivial change).
8011 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8013 * tests/local.at: Don't attempt to check for negated character
8014 classes in shell scripts. The test was too brittle.
8016 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8018 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8019 * doc/autoconf.texi (Limitations of Builtins): Document this
8020 limitation.
8022 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8024 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8025 common code; used in many places in the tree.
8026 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8027 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8029 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
8031 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
8032 messages when ac_unique_file is not found.
8033 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8034 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8035 commands, for consistency with AC_MSG_ERROR and such.
8037 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8039 * bin/Makefile.am: Merge the two rules for creating scripts.
8041 2005-05-23 Stepan Kasal <kasal@ucw.cz>
8043 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
8044 obsolete; it was never documented.
8045 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
8047 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8049 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8050 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8051 (ac_top_builddir): ... this ...
8052 (ac_top_build_prefix): ... to this; the old name is also kept, for
8053 backward compatibility.
8054 (ac_top_builddir_sub): New variable, without the trailing slash,
8055 always nonempty.
8056 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8057 * doc/autoconf.texi (Configuration Actions): Rename
8058 ac_top_builddir to ac_top_build_prefix.
8059 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8060 at_top_builddir to at_top_build_prefix.

8063 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8066 of confdefs.h .
8068 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8070 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8071 argument to m4_foreach. I guess it was necessary in the past,
8072 but I think it's a no-op now.
8074 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8076 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8077 ``cat <<_ACEOF'' commands to one.
8078 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8079 * lib/autoconf/status.m4: On various places, use expr instead of
8080 ``echo|sed.''
8081 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8082 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8083 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8084 a range.
8085 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8086 the wrong patterns between ``case'' and ``esac.'' The previous
8087 code had false positives.
8089 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8091 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8092 as on 2005-05-02.
8093 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8094 Mention LIBOBJDIR.

8155 * doc/autoconf.texi (Autoconf Language): Be more precise about
8156 quoting rules. Problems noted by Stepan Kasal.
8157 Also, throughout this document, be more careful about white space.
8158 "blank", "white space", and "space" all have different meanings
8159 and we should be careful to say what we mean.
8161 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8163 Fix C++ related problems reported by Werner Lemberg.
8164 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

8196 not newline.
8198 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8199 by AC_DEFINE; it was a mistake.
8200 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8202 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8204 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8206 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8208 * doc/autoconf.texi (External Software): Quadrigraphs are not

8210 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8211 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8212 comment and reduce m4_default([foo], []) to [foo].
8213 (m4_strip): Update the explanation.
8215 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8217 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8218 Remove core.conftest.* too; it's generated by Tru64 5.1.
8219 Problem reported by Jennis Pruett.
8220 * lib/autoconf/functions.m4
8221 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8222 Don't bother to remove core files; AC_RUN_IFELSE should do that
8223 for you.
8225 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8227 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8269 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):

8273 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8275 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8277 * NEWS: The configure command now warns you if you attempt to use
8278 a directory whose name contains a special character like space,
8279 newline, or "\".
8280 * doc/autoconf.texi (Installation Directory Variables): Allow
8281 "," in file names. Do not use \@; it's not a portable regexp.

8289 * doc/autoconf.texi (File System Conventions): Warn about
8290 unportable file names.
8291 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8292 (AC_INIT): Use it.
8293 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8294 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8295 ac_pwd, and quote srcdir.
8296 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8298 * doc/autoconf.texi: Fix some systematic formatting problems.
8299 ".)" needs a following @: if not at the end of a sentence, and
8300 similarly for "!)". "etc." should be preceded by a comma.
8301 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8303 2005-03-22 Bruno Haible <bruno@clisp.org>
8305 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8306 argument is often called 'build-aux'.
8308 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8310 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8311 macro AC_TRY_LINK is obsolete.
8312 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8313 `AC_CONFIG_FILES'.
8315 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8317 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8318 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8319 from a Common Lisp's `cl'.
8320 (AC_PROG_CXX): Behave according to the documentation: don't
8321 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8322 make the variable CCC precious; use `cl.exe', not `cl'.
8324 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8325 Alexandre Duret-Lutz <adl@gnu.org>
8327 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8328 /dev/null, as "configure" shouldn't read stdin, and this insulates
8329 us from problems (e.g., when testing for "cl"). Also, do this
8330 redirection before invoking "hostname" or "uname", and keep the
8331 original input stream available via...
8332 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8333 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8334 bother with "</dev/null" since it's now done at the top of
8335 'configure'.
8336 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8337 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8343 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8345 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8346 newline if neither \c nor -n work, as that would output two
8347 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8349 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8351 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8352 This causes that any required macros inside will get before the if.
8353 * doc/autoconf.texi (autom4te.cache): A typo.
8355 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8357 Undo previous change, except keep the change to
8358 lib/autoconf/programs.m4 that replaced grep with shell
8359 pattern-matching. This is because net-snmp configure reads stdin.
8360 Reported by Noah Misch.
8362 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8364 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8365 from /dev/null, as "configure" shouldn't read stdin, and this
8366 insulates us from problems (e.g., when testing for "cl").
8367 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8368 before invoking "hostname" or "uname".
8369 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8370 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8371 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8372 "</dev/null" since it's now done at the top of 'configure'.
8373 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8374 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8375 Also, replace grep with shell pattern-matching, to save a process.
8377 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8379 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8380 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8381 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8382 compiler.
8384 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8386 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8387 grep -q isn't portable. Improve grep -s explanation.
8388 Problem reported by Dan Manthey.
8390 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8392 * doc/autoconf.texi (Special Shell Variables): Clarify
8393 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8395 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8397 * doc/autoconf.texi: Use @acronym for DJGPP.
8398 Fix some @code's that should have been @env's, and vice versa.
8399 Sort environment variable names.
8400 Mention that shells no longer inherit IFS.
8401 Don't recommend PATH_SEPARATOR=';' so strongly.
8402 Mention that $RANDOM might expand to the empty string.
8403 "symlink" and "soft link" -> "symbolic link".
8404 Improve mktemp description (reported by Bruno Haible).
8406 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8408 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8409 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8410 Likewise.
8411 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):

8414 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8416 * NEWS: Mention AT_COPYRIGHT.
8418 * tests/local.at (AT_CMP): Use diff directly on input files rather
8419 than copying them.
8421 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8422 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8424 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8425 and Paul Eggert <eggert@cs.ucla.edu>

8434 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8435 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8436 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8437 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8438 (Standard regular expressions): New test.
8439 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8440 excess test name quoting.
8441 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8442 CPPFLAGS to `configure' instead of setting it in `configure'.
8444 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8445 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8446 on some platforms.
8448 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8449 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8451 * tests/local.at (AT_CMP): New macro.
8452 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

8456 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8457 * tests/c.at (Extensions): Do not exit early.

8477 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8479 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8480 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8482 Try not to generated lines of unlimited length, as POSIX places a
8483 2047-byte limit on line length of portable text files.
8484 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8485 Use newline as a separator, not space.
8486 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8487 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8488 space.
8490 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8492 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8493 as_func_*. Add test to check whether positional parameters
8494 are restored after function return.
8496 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8498 * doc/autoconf.texi (Special Shell Variables): Mention _,
8499 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8500 if they contain a lower-case letter. The DUALCASE problem was
8501 reported by Ralf Wildenhues.
8503 * bin/autoconf.as: Don't exit with status 0 after write failure
8504 with --help or --version.
8505 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

8511 Unicos 9 sed limitations.
8512 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

8516 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8518 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8519 care to echo the commands, so the user knows what's going on.
8520 Modified from a suggestion by Stepan Kasal.
8522 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

8530 Based on a proposed patch by Ralf Wildenhues.
8532 * man/Makefile.am (.x.1): Make sure the required generated files
8533 are up to date. Problem and original solution proposed by Stepan Kasal.
8534 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
8535 implicit-man-prerequisites): New rules, used by the above.

8541 2005-01-29 Stepan Kasal <kasal@ucw.cz>
8543 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8544 Update the long comment explaining it.
8546 m4_require no longer writes an ``is required by'' line to the
8547 execution stack. It contains only one bit of non-redundant
8548 information: that the macro was required, not called. And even
8549 this bit is useless in most situations: have you ever met a macro
8550 which both calls and requires the same macro?
8552 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8553 (_m4_defun_pro_outer): ... only via this macro, for the outermost
8554 macro.
8555 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
8556 (m4_expansion_stack_pop): Remove the misplaced comment.
8557 (m4_require): Don't put the ``is required by'' line to the
8558 execution stack; slightly improve the out-of-a-defun error message.
8559 (_m4_divert_grow): New macro, counter for the temporary diversions.
8560 (_m4_require_call): Use it.
8561 * tests/m4sugar.at (m4_require): Expect output without the
8562 ``is required by'' messages.
8564 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8566 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8567 rather than x for expr.
8569 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8570 this is safe.
8571 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8572 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8582 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
8583 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
8584 from masters, so that FileUtils.pm's update_file provide --force
8585 support.
8586 * bin/autoheader.in: Pass $force to update_file so that
8587 config.h.in is always recreated when --force.
8589 2005-01-24 Stepan Kasal <kasal@ucw.cz>
8591 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
8593 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8595 * doc/autoconf.texi (Limitations of Builtins): Clarify that
8596 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
8598 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8600 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8601 Warn about newline stripping in `` and $(). Update Solaris
8602 version to 9.
8603 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8604 X insulates us from future changes to Posix.
8605 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8606 stripping.
8608 2005-01-19 Stepan Kasal <kasal@ucw.cz>
8610 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

8613 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
8615 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

8626 ulongval to be static, to avoid unwanted GCC warning. Problem
8627 reported by Michael Jennings via Daniel Reed; see
8628 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8630 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8632 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8634 datadir, infodir, and mandir. Adjust argument parsing code.
8635 (_AC_INIT_HELP): Update help text.

8637 new variables.
8639 2005-01-04 Noah Misch <noah@cs.caltech.edu>
8641 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
8642 not seem to work, assume it does set $(MAKE).
8643 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
8645 2005-01-03 Stepan Kasal <kasal@ucw.cz>
8647 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

8653 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
8654 (_m4_divert_n_stack): New macro; the expansion is
8655 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8656 otherwise.
8657 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8658 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8659 stored in _m4_divert_diversion or _m4_divert_dump.
8660 (m4_divert_pop): When the parameter is given, compare the symbolic
8661 name with the last diversion pushed on the stack. Previously, the
8662 current diversion was compared with the numeric value of the
8663 diversion given as the parameter.
8664 (m4_require): If the macro hasn't been expanded yet, call ...
8665 (_m4_require_call): this new macro.
8667 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8698 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
8699 signals that the package uses Automake; a `Makefile.am' is typical but
8700 not essential. Reported by Magnus Therning.
8701 * tests/torture.at (autoreconf.): New banner.
8702 (autoreconf and non-AC configure): Rename to `Non-Autoconf
8703 AC_CONFIG_SUBDIRS'.

8972 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8973 "char c = '\200';" rather than "char c = 0x80;" as the

8978 to -qlanglvl=ansi. We don't want to disable extensions.

9091 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9092 "/usr/include", clear ac_x_includes instead of leaving it as "no"

9187 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9188 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9189 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9191 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9193 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9194 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9195 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9196 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9197 * lib/autom4te.in (Automake-preselections): Preselect
9198 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9200 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9202 * lib/autom4te.in (Automake-preselections): Preselect
9203 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9204 trace them.
9206 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9208 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9209 Tru64.
9210 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9211 Document problem with "`""`" in pdksh POSIX mode.
9213 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9215 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9216 with pdksh, too. Problem reported by Patrick Welche via
9217 Gary V. Vaughan.
9218 * doc/autoconf.texi (Shellology): Note that set -o posix is
9219 useful for pkdsh, too.
9221 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9223 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9224 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9225 Don't fail if ENV or BASH_ENV is readonly.
9226 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9227 etc. are read only. Problem reported by Ludovic Courtes.
9229 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9231 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9232 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9233 (trivial change)
9235 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9237 * doc/autoconf.texi (File System Conventions): Warn about
9238 names like "aux". Problem reported by Eric Blake.
9240 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9241 by zero instead of array size, so that we can use any arithmetic
9242 constant expression (instead of requiring an integer constant
9243 expression). This allows us to test expressions like DBL_MAX <
9244 LDBL_MAX, which didn't conform to the C standard using the old
9245 method.
9246 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9247 now that we can do floating-point tests at compile time.
9249 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9251 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9252 and LDBL_EPSILON, as the resulting expression isn't an
9253 integer constant expression and violates the C standard.
9254 Problem reported by Nelson H. F. Beebe. Also, check
9255 for "L" suffix, and check that long double doesn't have
9256 worse range or precision than double, that mixed-mode
9257 arithmetic doesn't generate a diagnostic, that double
9258 constants fit in long double.
9260 2004-06-03 Kevin Ryde <user42@zip.com.au>
9262 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9263 malloc(0) and realloc(NULL,size).
9265 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9266 Bob Proulx.
9268 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9270 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9271 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9272 by Jim Meyering.
9274 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9276 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9277 can be rewritten using if-then-else. Suggested by Bruno Haible.
9279 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9281 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9282 Problem reported by Stepan Kasal.
9284 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9286 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9287 change). Patch reported by Ralf Wildenhues in
9288 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9290 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9291 function F exists if the compiler and linker let you compile an
9292 expression like (F != 0). Recent versions of GCC optimize away
9293 the reference to F in that case, since every function address must
9294 be nonzero, so the link succeeds even if F does not exist.
9295 Problem reported by Manu in
9296 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9298 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9299 "Unix". Many uses changed.
9300 (Limitations of Builtins): Explain better why the ! command isn't
9301 portable.
9303 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9305 * lib/autom4te.in (Automake-preselections): Preselect
9306 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9308 2004-05-19 Kevin Ryde <user42@zip.com.au>
9310 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9311 referencing AC_FUNC_STRERROR_R.
9313 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9314 note pessimistic assumption when cross compiling.
9316 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9318 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9319 (until 2004) invoked subcommands with sh -e, contra POSIX.
9320 Reported by Kevin Ryde.
9322 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9324 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9325 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9326 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9327 `test -f " /usr/bin/grep"', which _always_ failed.
9328 (AC_PROG_SED): Ditto bogus PATH fix.
9329 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9330 requires that grep correctly supports _multiple_ `-e' options, rather
9331 than stating only that grep should accept `-e'.
9333 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9335 Port to C99, which requires that 'exit' be declared.
9337 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9338 to ensure that stdlib.h is included.
9339 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9340 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9341 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9342 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9343 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9344 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9345 when using 'exit' in a test; C99 requires that 'exit' be declared.
9347 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9349 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9350 now prefers 'grep' implementations that accept -e.
9351 (Limitations of Usual Tools): Describe problems of traditional
9352 egrep and fgrep with long input lines, and of traditional grep
9353 with -e.
9354 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9355 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9356 All callers changed. Append /usr/xpg4/bin to the PATH, for
9357 Solaris.
9358 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9359 the user with complaints about multiple -e options.
9360 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9361 Define it with AC_PROG_GREP.
9362 * configure.ac (AC_PROG_GREP): Add.
9363 * lib/freeze.mk (GREP): New macro.
9365 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9367 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9368 a possible candidate only after all others fail, rather than
9369 consulting it first. This improves backward compatibility by
9370 better reflecting the way shell selection occurred in previous
9371 versions of Autoconf, and should help to avoid triggering latent
9372 problems in other packages, such as the one in Automake where zsh
9373 is not handled robustly:
9374 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9375 Although it is not Autoconf's responsibility to work around
9376 problems in Automake, it nevertheless makes sense to avoid
9377 introducing unnecessary incompatibilites.
9379 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9380 Gary V. Vaughan <gary@gnu.org>
9382 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9383 how deeply nested we are when a suitable tool is found, set the
9384 ac_path_TOOL_found flag.
9385 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9386 nested we are in this macro. Break out of all 3 nested loops if
9387 ac_path_TOOL_found is set.
9389 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9391 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9392 of the _AS_PATH_WALK loop too if GNU flavor is found.
9394 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9396 * doc/autoconf.texi (Limitations of Make): Update documentation
9397 for `$<'. New entry `Long lines', based on a report from Simon
9398 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9399 paragraph about DJGPP, based on a mail from Richard Dawe.
9401 2004-04-20 Paul Eggert <eggert@twinsun.com>
9403 * tests/c.at (C keywords): Don't assume that GCC supports
9404 "restrict" and "inline", as sufficiently-old GCC versions do not
9405 (also, GCC configured to be in pedantic C89 mode does not).
9406 Problem reported by Sumit Pandya in:
9407 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9409 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9410 consider -g to work if it generates warnings when plain compiles
9411 don't. Problem reported by Braden McDaniel in:
9412 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9414 * doc/autoconf.texi (Slashes): New section, to document a problem
9415 reported by Jim Meyering in:
9416 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9418 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9419 linker output files before linking, to work around IRIX 6 linker bug.
9420 Problem reported by Rainer Orth in:
9421 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9423 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9425 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9426 best tool so far counter rely on the tool path variable name to
9427 avoid checks for one tool being affected by the results of running
9428 the length check on a previous tool.
9430 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9431 match expression argument, as different greps have different
9432 regular expression flavours.
9433 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9434 literals.
9435 (AC_PROG_EGREP): Pass 'EGREP$'.
9436 (AC_PROG_GREP): Pass 'GREP$'.
9438 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9440 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9441 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9443 2004-03-29 Paul Eggert <eggert@twinsun.com>
9445 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9446 Types, Specific Compiler Characteristics, System Services,
9447 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9448 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9449 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9450 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9451 Likewise.
9452 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9453 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9454 AC_TYPE_OFF_T): Likewise.
9455 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9456 Likewise.
9458 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9459 pacify libtool 1.5.2. Fix quoting problems in sed command.
9461 2004-03-28 Paul Eggert <eggert@twinsun.com>
9463 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9464 now defines HAVE_DECL_TZNAME if it is declared, when
9465 HAVE_STRUCT_TM_TM_ZONE is not defined.
9466 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9467 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9468 for HAVE_TZNAME.
9470 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9472 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9473 superfluous backslashing of quotes (") in sed expressions;
9474 thanks to Paul Eggert.
9476 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9478 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9479 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9480 H. F. Beebe for the bug report.
9482 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9484 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9485 quoted -cmdline argument in Portland Group compiler (bug
9486 reported by Jeffrey J. Barteet).
9488 2004-03-25 Kevin Ryde <user42@zip.com.au>
9490 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9491 (Run Time): ... here, where it's now mentioned.
9493 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
9495 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9496 inherits from language Autoconf-without-aclocal-m4.
9497 (Customizing autom4te): Adjust example; the cache must now be
9498 disabled for language Autoconf-without-aclocal-m4.
9500 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
9501 Nathanael Nerode <neroden@twcny.rr.com>

9511 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
9512 AC_CHECK_TOOLS.
9513 (Specifying Names): Document the reason for these future
9514 behavioral changes.
9515 * tests/mktests.sh: Do not generate tests for the
9516 new macros.
9517 * NEWS: Document these changes.
9519 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9520 they make TeX hang up.
9522 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9524 * NEWS: New macro AC_CHECK_ALIGNOF.
9525 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9526 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9527 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9528 vowel.
9529 (AC_CHECK_ALIGNOF): New macro.
9530 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9531 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9532 those for sizeof.
9534 2004-03-03 Paul Eggert <eggert@twinsun.com>
9536 * bin/Makefile.am (edit): Don't use $< in a context where
9537 POSIX doesn't require support for it. Use $@.in instead.
9538 Problem reported by Anthony N. Frasso in
9539 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9540 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9542 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9544 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9545 from the next generation of Libtool.
9546 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9548 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9550 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

9553 2004-02-18 Paul Eggert <eggert@twinsun.com>
9555 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9556 problem on QNX reported by Stephen Rasku in
9557 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9559 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9560 $(m4sh_m4f_dependencies); this removes a FIXME.
9561 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9562 (MAINTAINERCLEANFILES): Split into pieces,
9563 one per related section. Add $(srcdir)/wrapper.in.
9565 2004-02-09 Paul Eggert <eggert@twinsun.com>
9567 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9568 AC_SUBST provides no portable way to escape literal newlines.
9570 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9571 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9572 Darwin uses -lcrt2.o and there's little point to cataloging all
9573 the system variants. Partial fix reported by Andreas Waechter in:
9574 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9575 for bug reported by Nelson H. F. Beebe in:

9583 acobsolete.m4, suggested by Alexandre Duret-Lutz.
9585 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
9587 * bin/autoupdate.in: Define __file__ so that warnings
9588 refer to the correct file.
9589 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9590 the behavior of the third argument.
9591 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9592 correctly the behavior of the third argument. Document
9593 what the three macros that AU_DEFUN defines do. Fix
9594 warning message when the third argument includes $0
9595 (reported by Alexandre Duret-Lutz).
9597 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9598 Eric Sunshine <sunshine@sunshineco.com>
9599 Paul Eggert <eggert@twinsun.com>
9601 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9602 (AS_INIT): Output shell initialization there. Removed optional
9603 parameter. Expand _AS_SHELL_FN_SPY.
9604 (AS_INIT_WITH_SHELL_FN): Removed.
9605 (_AS_SHELL_FN_SPY): New macro.
9606 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9607 macros.
9608 (AS_SHELL_SANITIZE): Remove loop to find better shell
9609 and documentation for the parameter.
9610 (_AS_DETECT_BETTER_SHELL): Move it here.
9611 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
9612 (_AS_RUN): Move it here, support testing with eval.
9613 (AS_REQUIRE_SHELL_FN): Require shell functions when
9614 it is used.
9615 (_AS_LINENO_WORKS): Put around braces, we do not
9616 trigger the bash bug anymore.
9617 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9618 use AS_INIT_WITH_SHELL_FN.
9619 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9621 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9623 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
9624 * doc/autoconf.texi: Don't say that the third parameter
9625 is broken.
9626 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
9627 (AU_DEFUN): Honor the third parameter, create autoupdate
9628 macros with AU_DEFINE.
9629 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,

9643 of autoupdate.

9649 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

9651 the 2003-05-22 change, which removed the older years from the list.
9652 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9654 2004-01-27 Gary V. Vaughan <gary@gnu.org>

9659 possible.
9660 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
9661 AC_PROG_GREP.
9662 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
9663 egrep and fgrep respectively if $GREP -E/-F don't work.
9664 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9665 _AC_PROG_GREP, and AC_PROG_SED.
9666 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9667 longest input length accepted by a command.
9668 (AC_PROG_SED): Use it.
9669 * doc/autoconf.texi (Particular Programs): Document the changes.

9672 2004-01-27 Paul Eggert <eggert@twinsun.com>
9674 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

9676 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9677 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9679 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9680 bin/autoconf.in, config/Makefile.in, config/config.guess,
9681 config/config.sub, config/install-sh, config/mdate-sh,

9696 2004-01-26 Paul Eggert <eggert@twinsun.com>
9698 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9699 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9700 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9701 not <inttypes.h>. Problem reported by Tim Mooney in
9702 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9703 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9704 Likewise.
9706 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9707 otherwise "make check" fails because it forbids cmp (I guess
9708 because cmp treats files as binary on DOS-like systems).
9710 * tests/mktests.sh: Update copyright date to 2004, since some tests
9711 have changed in 2004.
9713 2004-01-23 Gary V. Vaughan <gary@gnu.org>

9716 non-truncating sed or gsed program in PATH.

9719 * NEWS: Updated.
9721 2004-01-15 Paul Eggert <eggert@twinsun.com>
9723 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9724 -std1 disables some useful extensions on Tru64. Problem reported
9725 by N. Lichtmaier in
9726 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9728 2004-01-14 Paul Eggert <eggert@twinsun.com>
9730 * doc/autoconf.texi (Programming in M4sh): Document that
9731 AS_MKDIR_P succeeds if the destination is a symbolic link
9732 to an existing directory.
9733 (Limitations of Usual Tools): Note that mkdir -p might not
9734 succeed on symlinks to directories.
9736 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9738 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9739 * bin/autoheader.in: Grammar fix in message.
9740 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9741 Test for dir before calling mkdir -p. (trivial changes)
9743 2004-01-13 Eric Blake <ebb9@byu.net>
9745 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9746 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9748 2004-01-10 Jim Meyering <jim@meyering.net>
9750 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9752 2004-01-09 Paul Eggert <eggert@twinsun.com>
9754 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9755 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9756 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9757 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9758 AC_COMPILE_IFELSE, since we now assume our caller invokes
9759 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9760 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9761 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9762 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9764 2004-01-07 Paul Eggert <eggert@twinsun.com>
9766 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9767 `"'...'"`, as it's confusing (and I suspect it may not work on
9768 some platforms). The code was incorrect anyway, as it assumed
9769 that \$ evaluated to itself in that context. Reported by
9770 Alexandre Duret-Lutz.
9772 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9774 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9780 example, and add more examples. Reported by Eric Sunshine.
9782 2004-01-05 Paul Eggert <eggert@twinsun.com>
9784 * doc/autoconf.texi (Limitations of Usual Tools):
9785 Remove warning against "rm -fr" introduced yesterday; it
9786 was a false alarm.
9788 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9789 autoscan, autoupdate, ifnames): Don't use chmod -w.
9790 * lib/Makefile.am (autom4te.cfg): Likewise.
9791 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9792 "chmod -w".

9795 Paolo Bonzini <bonzini@gnu.org>
9797 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9798 by doing lineno substitution only on lines containing "$LINENO".
9800 2004-01-04 Paul Eggert <eggert@twinsun.com>
9802 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9803 Use "rm -f" to remove conftest.sed, not plain "rm".
9804 Bug reported by David Relson in
9805 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9807 * Makefile.am (autom4te-update):
9808 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9809 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9810 * doc/autoconf.texi (Guidelines): Likewise.

9816 * tests/Makefile.am (clean-local): Likewise.
9817 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9818 srcdir): Likewise.
9819 * doc/autoconf.texi (Limitations of Usual Tools):
9820 Warn against "rm -fr".
9822 2004-01-03 Paul Eggert <eggert@twinsun.com>
9824 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9825 -c -o might not work. From a suggestion by Kevin Ryde.
9826 (C Compiler, Generating Sources, Limitations
9827 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9828 Don't put '-o' after non-options, as POSIX doesn't allow this.
9829 Mention that cc's name might be gcc or c89 or whatever.
9831 2004-01-04 Kevin Ryde <user42@zip.com.au>
9833 * doc/autoconf.texi: Add various further index entries.
9835 2003-12-29 Paul Eggert <eggert@twinsun.com>
9837 * bin/autoreconf.in (autoreconf_current_directory):
9838 Fix typo: mkdir without umask arg.
9840 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9842 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9843 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9844 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9845 explanation clearer.
9847 2003-12-24 Andreas Schwab <schwab@suse.de>
9849 * doc/autoconf.texi (Default Includes): Fix misspelling of
9850 AC_INCLUDES_DEFAULT.

9854 * configure.ac: Test if sh -n works.
9855 * configure: Regenerate.
9856 * tests/atlocal.in: Store the result here.
9857 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
9858 tools.at, looking in atlocal's ac_cv_sh_n_works instead
9859 of explicitly testing.
9860 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
9861 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
9862 * tests/tools.at (Syntax of the shell scripts): Simplify
9863 using AT_CHECK_SHELL_SYNTAX.
9864 (Syntax of the Perl scripts): Remove definition of
9865 AT_CHECK_PERL_SYNTAX.

9877 Extracted from AS_SHELL_SANITIZE.
9878 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
9879 macros.
9880 (AS_SHELL_SANITIZE): Move reinvocation code from
9881 _AS_LINENO_WORKS, use it to find out if shell
9882 functions work.
9883 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
9884 does not work.
9885 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
9886 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

9904 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

9947 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
9948 than $target since the latter is not usual, add guidelines on when to

9953 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10109 cross test.
10111 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
10113 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
10114 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10116 2003-10-10 Andreas Schwab <schwab@suse.de>
10118 * bin/autoheader.in: Avoid empty first line in --version and
10119 --help output.

10130 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10131 -mGLOB_options_string stuff for Intel ifc, which can cause
10132 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10133 pattern-matching instead of grep.
10135 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10137 * doc/autoconf.texi: Document new FC Fortran macros.

10145 * NEWS: Updated.
10147 2003-10-06 Gary V. Vaughan <gary@gnu.org>
10149 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
10150 -lcrtbegin.o to list of ignored flags and fix underquoting of
10151 -lcrt[01].o.
10153 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10155 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10156 cache variable instead of $G77 to decide whether to include -O2,
10157 since $G77 is specific to Fortran 77.
10159 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10161 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10162 free" flag. Re-order flags tested into rough order of popularity.
10164 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10166 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10167 arguments so that it can be used with syntax identical to
10168 AC_PROG_F77, and so that we can more easily decide to
10169 remove/deprecate the DIALECT optional argument in the future if it
10170 proves troublesome.
10171 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10172 non-freeform-supporting compilers. Document freeform flags.
10174 2003-10-03 Akim Demaille <akim@epita.fr>
10176 * configure.ac: Look for emacs, not macs.
10177 Reported by Eric Sunshine.
10179 2003-10-03 Akim Demaille <akim@epita.fr>
10181 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10182 * bin/autoreconf.in (autoreconf_current_directory): Create the
10183 AUX_DIR if needed, for sake of automake --add-missing etc.
10184 Suggested by Alexandre Duret-Lutz.
10186 2003-10-03 Akim Demaille <akim@epita.fr>
10188 * configure.ac: Quotation and formatting changes.
10189 (EMACS): Don't set it if it is not recent enough to support

10211 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
10213 2003-09-30 Akim Demaille <akim@epita.fr>
10215 * config/announce-gen (&print_news_deltas): Extracted from...
10216 (&print_changelog_deltas): here.
10217 (&news_file): Rename as...
10218 (@news_file): this.
10220 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10222 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10223 have been created when invoking the compiler.
10224 * tests/fortran.at (GNU Fortran 77): Quote $G77.
10226 2003-09-29 Akim Demaille <akim@epita.fr>
10228 Version 2.57e.

10235 Problem reported by Lars J. Aas in
10236 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10237 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10238 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10239 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10241 2003-09-26 Akim Demaille <akim@epita.fr>
10243 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10244 directory for AC_CONFIG_COMMANDS' first argument exists.
10245 This makes valid the invocation of _AC_SRCPATH that follows.
10246 Reported by Eric Sunshine.
10247 * doc/autoconf.texi (Configuration Commands): Adjust.
10249 2003-09-26 Akim Demaille <akim@epita.fr>
10251 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10252 Reported by Ralf Corsepius.
10254 2003-09-26 Akim Demaille <akim@epita.fr>
10256 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10257 arguments.
10258 Actually, use AU_ALIAS.
10259 From Bruno Haible.
10261 2003-09-26 Paul Eggert <eggert@twinsun.com>
10263 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

10268 2003-09-26 Akim Demaille <akim@epita.fr>
10270 The test suite are sometimes assigning timings incorrectly.
10271 Reported by Henk Krus.
10272 Diagnosed by Nicolas Joly.
10274 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10275 AT_help_all.
10276 Instead of making AT_help a sequence of assignments to grow
10277 $at_help_all, just make AT_help_all be the growing contents of
10278 $at_help_all, and make a single assignment in...
10279 (AT_INIT): here.
10280 (at_times_skip): Flip the meaning and rename as...
10281 (at_times_p): this.
10282 (AT_INIT): When summarizing the test that ran, remove
10283 $at_times_file after use, and check it is present before trying to
10284 use it.
10286 2003-09-25 Akim Demaille <akim@epita.fr>
10288 Version 2.57d.
10290 * bin/Makefile.am (edit): Handle '@configure_input@'.
10291 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10292 (ifnames): chmod -w.
10293 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10294 executables, not bin/ executables! Otherwise all the magic needed
10295 to find non installed files is turned off. This caused a failure
10296 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10297 as found in its environment (sent by tests/autoreconf): pointing
10298 to bin/autom4te that could not find its files.
10299 * tests/mktests.sh: Force the replacement of generated files, for
10300 the sake of "mv" program that are interactive when overwriting a
10301 -w file.
10302 * config/install-sh: Upgrade from CVS Automake.
10304 2003-09-23 Paul Eggert <eggert@twinsun.com>

10307 versus test -L issues.
10309 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10310 Paul Eggert <eggert@twinsun.com>
10312 Trivial change to support GCC's configuration procedure.
10313 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10314 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10315 about inconsistency if the preprocessor is set to give errors for
10316 any warning.

10333 from masters.
10335 2003-09-12 Akim Demaille <akim@epita.fr>
10337 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
10338 not asm/types.h.
10340 2003-09-11 Akim Demaille <akim@epita.fr>
10342 * doc/autoconf.texi (Header Portability): linux/random.h.
10343 From Peter Hendrickson.
10345 2003-09-10 Akim Demaille <akim@epita.fr>
10347 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10348 willing to edit the output files.
10350 2003-09-10 Akim Demaille <akim@epita.fr>
10352 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10353 and AC_FC_FREEFORM.
10354 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10355 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10357 2003-09-09 Akim Demaille <akim@epita.fr>

10366 trailing files.
10368 2003-09-07 Paul Eggert <eggert@twinsun.com>
10370 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10371 Improve the accuracy of the wording about obsolescence.
10372 From a suggestion by Ian Lance Taylor in
10373 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10375 2003-09-05 Paul Eggert <eggert@twinsun.com>
10377 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10378 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10380 2003-09-04 Akim Demaille <akim@epita.fr>
10382 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10383 AC_FUNC_WAIT3.
10385 2003-09-04 Akim Demaille <akim@epita.fr>
10387 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10388 (freeze): When exiting, use $exit_code.
10389 * lib/autoconf/fortran.m4: Comment changes.
10391 2003-09-04 Akim Demaille <akim@epita.fr>
10393 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10395 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10397 Add support for newer Fortran dialects. The F77 interface is
10398 unchanged, and continues to support Fortran 77. New FC macros
10399 correspond to all the old F77 macros, with output variables FC,
10400 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10401 available dialect, but older dialects can be specified. There are
10402 new macros AC_FC_SRCEXT to set the source extension, and
10403 AC_FC_FREEFORM to accept free-form source files.
10405 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10406 New macros.
10407 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10408 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10409 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
10410 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

10418 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
10419 AC_FC_SRCEXT, AC_FC_FREEFORM):
10420 New macros.
10421 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
10422 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10423 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10424 Rewrite in terms of the above.
10425 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10426 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
10427 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
10428 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10430 2003-09-02 Paul Eggert <eggert@twinsun.com>
10432 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10433 Document problems with timestamp resolution that 'make', 'cp -p', and
10434 'touch -r' have.
10436 2003-08-27 Akim Demaille <akim@epita.fr>
10438 * tests/m4sugar.at (cross_warning): Make sure to enable the
10439 output, so that we can track spurious m4sugar output.
10440 * tests/local.at: Require 2.57.
10441 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10442 are defaulted by AT_CHECK anyway.
10443 Use AT_CHECK_AUTOM4TE.
10444 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10445 missing dnl.
10447 2003-08-27 Akim Demaille <akim@epita.fr>
10449 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10450 when -Wobsolete is set.
10451 Set it on by default.
10452 Suggested by Klee Dienes.
10454 2003-08-27 Akim Demaille <akim@epita.fr>
10456 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

10498 Output stack traces in warnings.
10500 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10501 Replace the former...
10502 (m4_warn): Pass the call stack to _m4_warn.
10503 * bin/autom4te.in: Adjust to output the call stack.
10504 * tests/m4sugar.at (m4@&t@_warn): Adjust.

10524 &parse_WARNINGS.
10525 ($help): Use Autom4te::ChannelDefs::usage.
10526 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10527 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10529 2003-08-21 Akim Demaille <akim@epita.fr>
10531 First stab at preserving warnings between calls to autom4te,
10532 including when the cache is used.
10534 There are still several issues: (i) there are too many runs of m4
10535 (one for include, one for warnings, and some more), (ii) warnings
10536 spreading on several lines are not handled gracefully, (iii) the
10537 code meant to have the call stack display for errors does not work
10538 (its handling should move from m4 to autom4te).
10540 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10541 Use them.
10542 (@preselect): Add m4_warn.
10543 ($exit_status): Remove, use $exit_code.
10544 ($help): Use Autom4te::ChannelDefs::usage.
10545 (&handle_m4): No longer define the m4_warnings.
10546 At each run, extract and report the warnings.
10547 Always cache the result, including if the exit status is on
10548 failure, since if nothing changes, we should result in the same
10549 failure, hence we can use the cache.
10550 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10551 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10552 Remove.
10553 (m4_warn): Redefine as a do-nothing: it is its invocation that
10554 matters, as warnings are now reported via traces.
10555 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10556 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10557 the latter reveals calls to the former.
10559 Adjust the tests.
10561 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10563 2003-08-21 Akim Demaille <akim@epita.fr>

10594 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10595 * bin/autom4te: Adjust.
10596 In particular, be Autoconf tools are really silent when properly
10597 working, bind the verbosity of the 'note' channel to $verbose.
10598 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10599 (&xsystem, &contents): Remove, since they are exported by...
10600 * lib/Autom4te/FileUtils.pm: this.
10601 More perldoc.
10602 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10603 * lib/Autom4te/FileUtils.pm: here.
10605 2003-08-20 Akim Demaille <akim@epita.fr>
10607 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10608 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10609 from CVS Automake.
10611 2003-08-20 Akim Demaille <akim@epita.fr>
10613 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10614 (autom4te-update): New.

10637 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

10660 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10661 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10662 shorter column three. Add DESCRIPTION to log file content.
10664 2003-08-13 Derek Price <derek@ximbiot.com>
10666 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10667 output.
10669 2003-08-12 Derek Price <derek@ximbiot.com>
10671 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10672 (AT_CHECK_NOESCAPE): Move core functionality to...
10673 (_AT_CHECK): ...this new macro.
10675 2003-08-07 Derek Price <derek@ximbiot.com>
10677 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10678 (AT_CHECK_NOESCAPE): ...to this new macro.
10680 2003-07-31 Paul Eggert <eggert@twinsun.com>
10682 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10683 in Bash 2.01. Problem reported by Brian Gough in
10684 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10686 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10688 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10689 -lcrt1.o, for OS X. (trivial change)
10691 2003-07-07 Paul Eggert <eggert@twinsun.com>
10693 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10694 inside '#ifndef __cplusplus'. Problem reported by
10695 Bob Friesenhahn.
10697 2003-07-06 Bill Clarke <llib@computer.org>
10699 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10700 'long', not 'int', for benefit of Sun's recent C++ compilers
10701 (trivial change). See:
10702 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10703 (This really should be 'intptr_t', not 'long', but that would
10704 take more work.)
10706 2003-06-25 Akim Demaille <akim@epita.fr>
10708 * lib/Makefile.am (autom4te.cfg): Make it read only.
10709 Depend on Makefile since it contains substitutions.
10710 From Paolo Bonzini.
10711 * lib/autom4te.in (args): Add local.at? for Autotest args.
10712 This change was made on autom4te.cfg which is generated.
10713 Reported by Raja R. Harinath.
10715 2003-06-25 Akim Demaille <akim@epita.fr>
10717 * doc/autoconf.texi (Header Portability): sys/mount.h.
10718 From Gareth McCaughan.
10720 2003-06-23 Akim Demaille <akim@epita.fr>
10722 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10723 not all of them. This fixes 1. the fact that when testing
10724 Autoconf there are many many config.log, 2. the incorrect use of
10725 top_srcdir to find config.log.
10726 Don't mix the detailed output of failed test with the summary of
10727 failures. Rather, append detailed log afterwards.
10729 2003-06-23 Akim Demaille <akim@epita.fr>
10731 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10732 always run: output config.log on $at_group_log.
10734 2003-06-23 Akim Demaille <akim@epita.fr>
10736 * tests/torture.at (#define header templates): Don't use quotes in
10737 C++ comments as it puzzles Emacs' sh font-lock-mode.
10739 2003-06-23 Akim Demaille <akim@epita.fr>
10741 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10742 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10743 * tests/atspecific.m4: Rename as...
10744 * tests/local.at: This.
10745 * tests/suite.at: Move the globals into...
10746 * tests/local.at: here.
10747 * tests/Makefile.am: Adjust.
10748 * doc/autoconf.texi (testsuite Scripts): Adjust.
10750 2003-06-21 Kevin Ryde <user42@zip.com.au>
10752 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10753 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10754 ensuring we add -std1 for full-ANSI.
10756 * doc/autoconf.texi (hdrindex): New macro.
10757 Add index entries for portability of various standard header files.
10759 2003-06-20 Akim Demaille <akim@epita.fr>
10761 * configure.ac: Bump to 2.57b.
10763 2003-06-20 Akim Demaille <akim@epita.fr>
10765 Version 2.57a.
10767 2003-06-20 Akim Demaille <akim@epita.fr>
10769 * bin/autom4te.in: Don't rely on $HOME being defined.
10770 Reported by Marc Espie as PR/233.
10772 2003-06-20 Akim Demaille <akim@epita.fr>
10774 * lib/autotest/general.m4: Use at_times_file only if used.
10775 From Nicolas Joly.
10777 2003-06-20 Akim Demaille <akim@epita.fr>
10779 * config/config.guess, config/config.sub, config/elisp-comp,
10780 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
10781 Update from masters.
10783 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10785 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10786 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10787 (TEST_SCRIPT): New diversion.
10788 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10789 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10790 (AT_INIT): Support for expected failures.
10792 2003-06-02 Akim Demaille <akim@epita.fr>
10794 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10795 changes.
10796 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10797 Autoconf nor Automake.
10798 (&contents): New, from Automake.
10799 PODify.
10801 2003-05-28 Paul Eggert <eggert@twinsun.com>
10803 * NEWS, doc/autoconf.texi (Particular Functions),
10804 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10805 is the inverse of localtime.
10807 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10809 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10810 (handle_exec_errors): New function. Work around $! being
10811 altered by WEXITSTATUS.
10812 (xqx, xsystem): Use handle_exec_errors.
10814 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10816 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10817 Do not call `_exit()', simply modify `$?'.
10818 (xsystem): Reset $! before running system, and check it afterward.
10819 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10820 63 for version mismatches.
10822 2003-05-23 Akim Demaille <akim@epita.fr>
10824 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10825 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10826 the middle of a line).
10827 * lib/m4sugar/m4sugar.m4: Likewise.
10828 Remove useless spaces in comments.
10830 2003-05-23 Akim Demaille <akim@epita.fr>
10832 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10833 exit 63, so that we (or Automake's "missing") can tell the
10834 difference with a plain failure.
10835 * doc/autoconf.texi (Notices): Adjust.
10837 2003-05-23 Akim Demaille <akim@epita.fr>
10839 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10840 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10841 White spaces cleanup.
10843 2003-05-22 Jim Meyering <jim@meyering.net>
10844 Paul Eggert <eggert@twinsun.com>
10846 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10847 Remove `#include <stdlib.h>' from the list; we should never
10848 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10849 resulting namespace pollution would cause other tests to fail.
10850 Configure scripts run with some older versions of g++ and HP's
10851 aCC would fail due to such an #include. Problems reported by
10852 Matthew Mueller in <http://bugs.debian.org/120704> and by
10853 Keith Bostic in
10854 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10855 In the test, use the test declaration before including <stdlib.h>,
10856 as that's closer to how it'll be used.
10858 2003-05-23 Akim Demaille <akim@epita.fr>
10860 * doc/autoconf.texi (Header Portability): ucred.h.
10861 From Ian Redfern.
10863 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10865 Overhaul Autotest's logging: generate separate log files
10866 in testsuite.dir/NNN/testsuite.log, and append them to
10867 testsuite.log instead of re-running the test verbosely.
10869 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10870 file descriptor, write 0 to at_status_file instead of setting
10871 at_status=0, initialize some new variables (at_status_file,
10872 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10873 to rerun the tests, instead append the at_group_log to the
10874 at_suite_log when a test fails.
10875 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10876 with the AS_MESSAGE_LOG_FD redirected to stdout.
10877 (AT_CLEANUP): save the output status in $at_status_file
10878 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10879 its original place.
10880 (AT_CHECK): since tests are run with a redirected stdout,
10881 and used to be re-run in verbose mode, turn some $at_verbose
10882 into echo, and don't redirect the output of testing stdout
10883 and stderr.
10885 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10886 the name of the debugging directory and information about
10887 its contents.
10889 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10891 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10892 parameter.
10894 2003-05-22 Akim Demaille <akim@epita.fr>
10896 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
10897 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
10898 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4
10899 * lib/autoconf/status.m4: Fix and adjust copyright notices.

10914 Whitespace clean up.
10915 Suggested by Jim Meyering.
10917 2003-05-22 Akim Demaille <akim@epita.fr>
10919 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
10920 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
10921 Reported by Jim Meyering.
10923 2003-05-22 Akim Demaille <akim@epita.fr>
10925 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
10926 Add AC_HELP_STRING to the obsolete macros section.
10927 Typos.
10928 Use '@.' for sentences that ended in a capital letter.
10929 From Art Haas.

10947 2003-05-19 Paul Eggert <eggert@twinsun.com>
10949 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:
10950 Remove non-ASCII characters.
10952 2003-05-18 Paolo Bonzini <bonzini@gnu.org>
10954 * tests/semantics.at (AC_SEARCH_LIBS): New test.
10955 * tests/semantics.at (AC_CHECK_HEADERS_OLD,
10956 AC_CHECK_HEADERS_NEW): New tests.
10958 2003-05-17 Akim Demaille <akim@epita.fr>
10960 * lib/autoconf/functions.m4: Use the default includes so that
10961 memcmp be declared before being tested.
10962 Reported by Sander Niemeijer.
10963 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
10964 * doc/autoconf.texi (Default Includes): Document
10965 AC_INCLUDES_DEFAULT.
10967 2003-05-17 Akim Demaille <akim@epita.fr>
10969 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
10970 * doc/autoconf.texi (Obsolete Macros): Adjust.
10971 Reported by Werner LEMBERG and Debian Bug 190886.
10973 2003-05-16 Akim Demaille <akim@epita.fr>
10975 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
10976 user name space clashes.
10977 Reported by Bruno Haible.
10979 2003-05-16 Akim Demaille <akim@epita.fr>
10981 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10982 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
10983 them uniform, and more robust to Perl special characters.
10984 Reported by Martin Mokrejs.
10986 2003-05-14 Akim Demaille <akim@epita.fr>

11004 and truncate.
11006 2003-05-06 Akim Demaille <akim@epita.fr>
11008 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11009 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11010 by aclocal.m4 is changed it might require the importing of another
11011 m4 extension file, i.e., aclocal must be run.
11013 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11014 (&parse_args): Use --force with aclocal if required and supported.
11015 (&autoreconf_current_directory): Use &run_aclocal.

11028 2003-04-29 Derek Price <derek@ximbiot.com>
11030 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11031 seperator with m4_append_uniq(). It doesn't work.
11032 (AT_CLEANUP): Add `;' to end of at_help_all.
11033 (AT_INIT): Allow --keywords to be specified more than once. When
11034 grepping $at_help_all for keywords, use the field and keyword
11035 seperators to ensure a complete keyword match. Alter at_prev handling
11036 to support the new --keywords behavior.
11038 2003-04-27 Karl Berry <karl@freefriends.org>
11040 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11041 align better with others. I also made some of the individual
11042 entries on one line, for brevity and to make it easier for me to
11043 sort my dir-example file in the Texinfo distribution :).

11083 New.
11084 Use them.
11085 * doc/Makefile.am (CLEANFILES): Adjust.

11114 * tests/torture.at (Configuring subdirectories): Require aclocal
11115 1.4, otherwise the test fails, as it does support configure.ac.
11116 This fixes the "test 40 failed" bug reports.
11118 2003-03-28 Akim Demaille <akim@epita.fr>
11120 * doc/autoconf.texi (C Compiler): `#line' portability.

11126 layout in order to allow scripting around test groups.
11128 2003-03-27 Derek Price <derek@ximbiot.com>
11130 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
11131 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
11132 use new diversions in preparation for accepting new arguments and

11146 2003-03-26 Derek Price <derek@ximbiot.com>
11148 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11149 sense. Verbosify the diversion definitions comment.
11151 2003-03-26 Derek Price <derek@ximbiot.com>
11153 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
11154 AS_PREPARE.

11175 file name for the m4 program, when it has an "exe" file extension.
11176 DJGPP's error messages include the error code in brackets -
11177 remove the error code during normalization.

11187 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11188 Tru64 make in the "target lookup" section.
11189 (Automake): Automake 1.5+ no longer requires special tools to be
11190 present on the developer's host.
11192 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11194 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
11195 to a shell that can handle redirection or quoting correctly.

11206 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
11207 to cope with DOS-style absolute paths, when constructing
11208 ${ac_make}.
11210 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11211 When constructing paths with IFS=:, quote the path. If we're
11212 constructing a DOS-style absolute path, we don't want to split it
11213 on the colon.
11215 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11216 in description.
11218 2003-02-25 Pavel Roskin <proski@gnu.org>
11220 * bin/autoheader.in: Add missing newline when printing
11221 suggestion how change AC_DEFINE call.
11223 2003-02-24 Paul Eggert <eggert@twinsun.com>
11225 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
11226 2002-09-01 patch by replacing "test -n" with "test -z".
11227 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
11228 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
11230 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11231 to fix a mismatch between example and discussion.
11233 2003-02-24 Kevin Ryde <user42@zip.com.au>
11235 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11236 format starting with "-".
11238 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11240 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11241 is not portable inside Makefile.
11243 2003-02-20 Akim Demaille <akim@epita.fr>
11245 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11246 compiler says yeah, but preproc says nope, compiler is right.
11247 Conversely, prompt the reader to send a bug report to the
11248 maintainers of the package, not of Autoconf.
11250 2003-02-20 Klee Dienes <kdienes@apple.com>
11252 * bin/autoreconf.in (autoreconf_current_directory): Properly
11253 handle an empty aclocal.m4.

11263 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11264 innocuous variant befor including <limits.h> or <assert.h>. This
11265 works around a bug reported by Albert Chin: HP-UX 11i
11266 (and earlier versions) have a <limits.h> that declares
11267 gettimeofday and many other functions.
11269 2002-12-03 Paul Eggert <eggert@twinsun.com>
11271 Version 2.57.
11273 * NEWS, configure.ac: Update version.
11275 * doc/fdl.texi: Upgrade to FDL version 1.2.
11277 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11278 nontrivially in main's body, so that f's external declaration is
11279 not optimized away in AIX. This should fix the bug reported by
11280 Martin Frydl in
11281 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11283 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11284 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11285 defined, to support freestanding compilers. This should fix the
11286 bug reported by Momchil Velkov in
11287 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11289 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11290 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11291 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11292 by Simon Josefsson in
11293 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11295 * Makefile.maint (www-gnu): New macro.
11296 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11297 the location has moved.
11299 2002-12-02 Martin Frydl <martin@systinet.com>
11301 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11302 \(.*\) match is too long and there is something more to be checked.
11303 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11305 2002-11-15 Akim Demaille <akim@epita.fr>
11307 Version 2.56.
11309 * config/install-sh: chmod +x.
11310 From Paul Eggert.
11311 * config/move-if-change: Indenting changes.
11312 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11313 * configure.ac (AM_INIT_AUTOMAKE): here.
11314 Require 1.7.1.
11316 2002-11-14 Akim Demaille <akim@epita.fr>
11318 Version 2.55.
11320 * config/config.guess, config/config.sub, config/install-sh:
11321 Update from masters.
11323 2002-11-14 Akim Demaille <akim@epita.fr>
11325 * Makefile.maint: Sync with Bison, i.e.:
11326 (po-check): Scan .l and .y files instead of the
11327 .c and the .h files that they generate. This fixes the bug
11328 reported by Tim Van Holder in:
11329 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11330 Look for N_ as well as for _. Try to avoid matching #define for
11331 N_ and _.
11332 From Paul Eggert.
11334 2002-11-14 Akim Demaille <akim@epita.fr>
11336 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11337 From Paul Eggert and Albert Chin-A-Young.
11339 2002-11-14 Akim Demaille <akim@epita.fr>
11341 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11342 From Paul Eggert and Albert Chin-A-Young.
11344 2002-11-14 Kevin Ryde <user42@zip.com.au>
11346 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11347 than assigning in main, to avoid HP cc +O3 optimizing it away.
11349 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11351 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11352 option. Process --recheck after parsing all options. Pass -q
11353 option to configure on --recheck.
11354 (AC_OUTPUT): Pass -q from configure to config.status.
11355 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11356 arguments to record.
11357 * doc/autoconf.texi (config.status Invocation): Document
11358 config.status -q option.
11360 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11362 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11363 Makefile.in if Makefile.am exists.
11364 (output): Strip `.am' from Makefiles. Don't
11365 output AC_CONFIG_FILES if no Makefiles were found.
11367 2002-11-07 Akim Demaille <akim@epita.fr>
11369 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

11374 2002-11-06 Akim Demaille <akim@epita.fr>
11376 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11377 declaration in extern "C" too.
11378 Reported by Roberto Bagnara.
11380 2002-11-06 Akim Demaille <akim@epita.fr>
11382 * tests/torture.at (Configuring subdirectories): Don't use grep
11383 -w.
11384 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
11385 Reported by Ezra Peisach.

11389 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11390 Remove.
11391 We _have_ to stop using the old compatibility scheme that tried to
11392 avoid useless backslashes because Libtool 1.4.3 contains a
11393 AC_DEFINE([error_t], [int],
11394 [Define to a type to use for \`error_t' if it is not
11395 otherwise available.])
11396 We _have_ to quote the single quote and backslashes with \. The
11397 old compatibility scheme saw that ` was backslashed, and therefore
11398 did not quote the single quote. Hence before this patch, Autoconf
11399 was not compatible with Libtool.
11401 2002-11-04 Paul Eggert <eggert@twinsun.com>
11403 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11404 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11405 LC_NAME, LC_PAPER, LC_TELEPHONE.

11408 2002-11-04 Akim Demaille <akim@epita.fr>
11410 Version 2.54c.
11412 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11413 New.
11414 * config/texinfo.tex: Update.
11416 2002-11-03 Akim Demaille <akim@epita.fr>
11418 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11419 from...
11420 (&autoreconf): here.
11421 ($help, $make, &parse_args, &autoreconf_current_directory):
11422 Support -m/--make.
11423 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11425 2002-10-31 Bruno Haible <bruno@clisp.org>

11431 to ac_cv_func_realloc_0_nonnull.
11432 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
11434 2002-10-31 Akim Demaille <akim@epita.fr>
11436 The test suite was no longer checking for trailing envvars and files.
11438 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
11439 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11441 2002-10-31 Akim Demaille <akim@epita.fr>
11443 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11444 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11445 Make variable, not a shell variable.
11446 Suggested by Bruno Haible.
11448 2002-10-31 Akim Demaille <akim@epita.fr>
11450 * bin/autom4te.in (load_configuration): Reject #args out of any
11451 language.
11453 2002-10-31 Akim Demaille <akim@epita.fr>
11455 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
11456 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
11457 (_AC_RUN_IFELSE): Use it.
11458 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
11459 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
11460 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
11461 inline it.
11463 2002-10-30 Akim Demaille <akim@epita.fr>
11465 * bin/autom4te.in (&parse_args, $help): Support --no-cache.
11466 * doc/autoconf.texi (autom4te Invocation): Adjust.
11467 Suggested by Tim van Holder.
11469 2002-10-29 Paul Eggert <eggert@twinsun.com>
11471 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11472 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11473 Problem reported by Bruno Haible.
11475 2002-10-29 Akim Demaille <akim@epita.fr>
11477 * doc/autoconf.texi (Header Templates): Put also in words what the
11478 pictures says to assist free style readers.
11479 (Customizing autom4te): s/--cache=/--cache /.
11481 2002-10-29 Akim Demaille <akim@epita.fr>

11731 2002-10-22 Akim Demaille <akim@epita.fr>
11733 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

11744 (_AS_QUOTE): Accept $2 as list of characters to quote.
11745 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11746 Quote for Perl, not sh.
11747 * bin/autoheader.in: When $debug, report the file which is

11784 (ansi2knr.c-url_prefix): Remove.
11786 2002-10-16 Akim Demaille <akim@epita.fr>
11788 Because of caching, some files that no longer exist and are no
11789 longer required can still cause errors.
11790 Reported by Alexandre Duret-Lutz.
11792 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11793 to frozen files in @ARGV, as @ARGV must remain being a list of

11796 (&freeze): Use &error.
11797 (&up_to_date): If a file that was included according to the cache
11798 is no longer there, then the output is out dated.

11800 --force is given.
11801 * tests/tools.at (autom4te cache): New.
11803 2002-10-16 Akim Demaille <akim@epita.fr>

11806 * bin/autoupdate.in (&parse_args): Kill old options.
11807 * bin/autoreconf.in (&parse_args): Remove dead options.
11808 Factor some code.
11809 (&autoreconf): Report the directories we enter *and leave*, so
11810 that error messages can be easily located, and use GNU Make
11811 format, so that Emacs' compile mode understands us.
11812 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11813 if some file was changed instead of `print'.
11814 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11815 (&parse_args): Remove the dead options.

11828 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

11843 of `precious'.
11845 2002-10-11 Akim Demaille <akim@epita.fr>
11847 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11848 file name to enable parallel executions.
11849 From Sam Varshavchik.
11851 2002-10-08 Akim Demaille <akim@epita.fr>
11853 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11854 aclocal invocation, as Gettext macros might not be visible to
11855 aclocal.
11856 Instead of blindly running autopoint, scan configure.ac (not the
11857 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11858 Reported by Paul D. Smith.
11860 2002-10-08 Paul Eggert <eggert@twinsun.com>
11862 Work around problems found when POSIXLY_CORRECT=1 is set.
11863 None of this seems to have anything to do with POSIX, really,
11864 but it's how Perl getopt works.
11865 * bin/autom4te.in (parse_args): Configure GetOpt with
11866 "permute", too.
11867 * doc/autoconf.texi (Invoking autom4te):
11868 --warning -> --warnings.
11869 * lib/autom4te.in: --warning -> --warnings.

11888 2002-09-28 Akim Demaille <akim@epita.fr>
11890 * tests/torture.at (Configuring subdirectories): Be robust to
11891 users who use config.site to require for a cache: in this case,
11892 the two last configure runs, using two different sets of
11893 arguments, trigger a legitimate error.
11895 2002-09-28 Akim Demaille <akim@epita.fr>
11897 * tests/m4sh.at (Functions Support, Functions and return Support):
11898 New.

11906 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11908 2002-09-28 Akim Demaille <akim@epita.fr>
11910 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11911 (tm_zone): Move their rules to...
11912 * lib/autoconf/types.m4: here, using AN_ macros.
11913 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11914 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11915 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

11928 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11929 (.m4.m4f): Don't pass --prepend-include, since that's done by
11930 tests/autom4te itself.
11931 * lib/autoscan/Makefile.am: Include freeze.mk.
11932 (autoscan.list): New target --this file is no longer a source.
11933 (autoscan.pre): New file.
11935 2002-09-28 Akim Demaille <akim@epita.fr>
11937 * bin/autoscan.in (@kinds): Make them singular.
11938 Adjust all uses.
11939 (&init_tables): When --debug, report the list of rules to ease
11940 tracking changes in autoscan.list.
11941 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11943 2002-09-28 Akim Demaille <akim@epita.fr>

11949 * bin/autoscan.in (&init_tables): Adjust.
11951 2002-09-28 Akim Demaille <akim@epita.fr>
11953 * lib/autoscan/functions, lib/autoscan/headers,
11954 * lib/autoscan/identifiers, lib/autoscan/makevars,
11955 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11956 `functions' line is now prefixed with `function:'.
11957 * bin/autoscan.in (&init_tables): Adjust.
11959 2002-09-28 Akim Demaille <akim@epita.fr>
11961 From now on, autoscan files must always map a macro name to a
11962 word: there is no `default' macro for autoscan.
11964 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11965 all.
11966 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11967 explicit.
11969 2002-09-28 Akim Demaille <akim@epita.fr>
11971 * bin/autoscan.in (%c_keywords): Remove.
11972 (&used): Keep only track of the words we might be interested in.
11973 (&output_kind): It is no longer needed to look for non active
11974 checks.
11976 2002-09-27 Akim Demaille <akim@epita.fr>
11978 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11979 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11980 * lib/autoscan/functions: Adjust.
11981 * doc/autoconf.texi (Particular Functions): Adjust.
11983 2002-09-27 Akim Demaille <akim@epita.fr>
11985 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11986 from /tmp.
11987 Thanks to Bill Moseley and Paul Eggert.
11988 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11989 the tmpdir must be created.
11990 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp

11995 * bin/autoscan.in: Improve the comments.
11996 (&parse_args): Drop obsolete undocumented options.

12001 2002-09-26 Akim Demaille <akim@epita.fr>
12003 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12004 Reported by Ralf Corsepius.
12005 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12007 2002-09-26 Akim Demaille <akim@epita.fr>
12009 Single suffix rules and seperated dependencies are not portable.

12013 Separated Dependencies'.
12014 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12015 (ifnames, autoscan, autom4te): Un-factor into several rules.
12017 2002-09-25 Paul Eggert <eggert@twinsun.com>
12019 * BUGS (Interoperability bugs): New section. Mention libtool
12020 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12022 2002-09-24 Paul Eggert <eggert@twinsun.com>
12024 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12025 make handles suffix-rules differently from GNU make.
12027 * bin/Makefile.am (SUFFIXES, .in): Remove.
12028 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12029 Move the body of the old .in rule here.
12031 2002-09-16 Akim Demaille <akim@epita.fr>
12033 i960 compilers create `b.out' files by default.
12034 Reported by Ralf Corsepius.
12036 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12037 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12039 2002-09-13 Paul Eggert <eggert@twinsun.com>
12041 * doc/autoconf.texi (Particular Headers): Remove obsolete
12042 reference to `struct timezone' in the description of
12043 AC_HEADER_TIME.
12045 2002-09-13 Akim Demaille <akim@epita.fr>
12047 Version 2.54.
12049 * config/config.sub, config/config.guess: Update.
12050 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12051 * Makefile.am: Adjust.
12053 2002-09-13 Akim Demaille <akim@epita.fr>
12055 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12056 reading config.log when the compiler is rejected.
12057 Suggested by Guido Draheim.
12059 2002-09-13 Akim Demaille <akim@epita.fr>
12061 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12062 (chdir_init) might hang when stat'ing mounted directories.
12063 Reported by Vance Shipley.
12065 2002-09-12 Akim Demaille <akim@epita.fr>
12067 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12068 the lists.
12070 2002-09-12 Akim Demaille <akim@epita.fr>
12072 * doc/autoconf.texi (Defining Symbols): Present two different
12073 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12074 difference between 1 argument calls, and 2-3 argument calls.
12076 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12078 * doc/autoconf.texi: Review grammar and punctuation.
12080 2002-09-11 Paul Eggert <eggert@twinsun.com>
12082 * doc/autoconf.texi: Fix minor formatting, spelling, and
12083 grammatical typos.
12084 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12085 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12086 is obsolescent.
12088 2002-09-11 Akim Demaille <akim@epita.fr>
12090 * doc/autoconf.texi (Questions): Rename as...
12091 (FAQ): this.
12092 (Defining Directories): New.
12094 2002-09-09 Akim Demaille <akim@epita.fr>
12096 * doc/autoconf.texi (Making testsuite Scripts): Update.
12097 Suggested by Nishio Futoshi.
12099 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12101 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12102 plain `@' is wanted.
12104 2002-09-09 Akim Demaille <akim@epita.fr>
12106 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12107 `duplicates', since the algorithm was too naive and could keep
12108 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12109 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12110 Reported by Ralf Corsepius.
12111 * tests/torture.at (Configuring subdirectories): Exercise these
12112 cases.
12114 2002-09-09 Akim Demaille <akim@epita.fr>
12116 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12117 looking for a replacement file.
12118 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12119 directory is relative.
12120 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12121 directory definition.
12122 Reported by Andreas Schwab and Jim Meyering.
12124 2002-09-06 Akim Demaille <akim@epita.fr>
12126 * doc/autoconf.texi (Setting Output Variables): Clarify what
12127 precious variables are.
12128 Suggested by Pontus Skoeld.
12130 2002-09-05 Akim Demaille <akim@epita.fr>
12132 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12133 (ifnames, autoscan, autom4te): Since we don't only depend on
12134 configure.ac variables (such as VERSION etc.), but also on prefix
12135 and so forth, depend on Makefile, not configure.ac.
12136 Reported by Alexandre Duret-Lutz.
12137 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12139 2002-09-05 Kevin Ryde <user42@zip.com.au>
12141 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12142 doesn't seem to be confined to ia64, just say "some versions".
12144 2002-09-04 Akim Demaille <akim@epita.fr>
12146 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12147 Automake 1.6c.
12148 * Makefile.am (maintainer-clean-local): Remove.
12149 (MAINTAINERCLEANFILES): Remove COPYING.
12151 2002-09-03 Paul Eggert <eggert@twinsun.com>
12153 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12154 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12155 Brinkmann.
12157 2002-09-03 Akim Demaille <akim@epita.fr>
12159 * configure.ac: Bump to 2.53d.
12160 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12161 as of today, on Automake's team suggestion.
12163 2002-09-03 Akim Demaille <akim@epita.fr>
12165 Version 2.53c.
12167 2002-09-02 Akim Demaille <akim@epita.fr>
12169 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12170 SITE_MACRO_DIR.
12171 * configure.ac: Disable SITE_MACRO_DIR.
12173 2002-09-02 Jim Meyering <meyering@lucent.com>
12175 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12176 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12177 Also, tweak grammar: s/make sure to/be sure to/.
12179 2002-09-02 Paul Eggert <eggert@twinsun.com>
12181 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12182 directory names are generally preferable to physical names.
12184 2002-09-02 Akim Demaille <akim@epita.fr>
12186 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12187 Reported by Raja R. Harinath.
12188 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12189 * bin/autoupdate.in: Use error instead of die.
12191 2002-09-01 Paul Eggert <eggert@twinsun.com>
12193 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12194 ordinary shell concatenation rather than echo+tr+sed command that
12195 runs afoul of a long-line-related sed bug in Solaris 8.
12197 * bin/autoheader.in (parse_args): --warning -> --warnings.
12199 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12200 stdout, as traditional "ls" does.
12201 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12202 _AC_COMPILER_EXEEXT_O): Likewise.
12203 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12205 * bin/autoconf.as: Add --prepend-include option. This patch was
12206 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12207 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12209 * bin/autoconf.in, configure: Regenerate.
12211 * doc/autoconf.texi (Special Shell Variables): Mention
12212 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12214 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12215 MAILPATH and set PS1, PS2, PS4 to default values, to work
12216 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12217 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12218 the Autoconf documentation specifies; fall back to "unset" only if
12219 this fails. Use a shell for-loop for this rather than an m4 loop,
12220 to shorten the output script.
12222 2002-08-30 Paul Eggert <eggert@twinsun.com>
12224 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12225 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12226 for the CDPATH problem. Document PWD.
12227 (Limitations of Builtins): Document the problem that "cd $foo" and
12228 "ls $foo" may refer to different directories in shells conforming
12229 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12230 example, since the old example is now out of date.
12232 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12233 FOO" and "ls FOO" talk about different directories; this catches
12234 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12235 spaghetti.
12237 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12238 of rolling our own unset.
12239 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12240 in practice we needn't worry about CDPATH if unset doesn't work.
12242 * Makefile.in, aclocal.m4, bin/Makefile.in,
12243 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12244 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12245 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12246 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12247 tests/Makefile.in: Regenerate with Automake 1.6.3.
12249 * config/config.guess, config/config.sub, config/mkinstalldirs:
12250 Update.
12252 * configure: Regenerate with self.
12254 2002-08-30 Kevin Ryde <user42@zip.com.au>
12256 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12257 default output.
12259 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12261 * bin/autom4te.in (Request::load): Correctly test for "do" read
12262 failure.
12264 2002-08-29 Akim Demaille <akim@epita.fr>
12266 * lib/Autom4te/General.pm (&xqx): New.
12267 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12268 hand, which is not portable.
12269 (&error): New.
12270 * bin/autom4te.in: Use them.
12271 Use &error instead of die.
12272 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12273 Adjust.
12275 2002-08-17 Paul Eggert <eggert@twinsun.com>
12277 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12278 default list of compilers to try, since it was long ago superseded
12279 by the ksh fc builtin. Suggested by Steven G. Johnson.
12281 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12283 * doc/autoconf.texi (Invoking autom4te): End the option table,
12284 fixing a bug introduced by the previous patch.
12285 (Limitations of Make): Add a 'target lookup' subentry in the
12286 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12288 2002-07-29 Mark D. Roth <roth@feep.net>
12290 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12291 options and use $AUTOM4TE_PATH.
12292 * doc/autoconf.texi: Remove documentation of autom4te
12293 --include-envvar and --site-macro-subdir options and document
12294 use of $AUTOM4TE_PATH.
12295 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12296 arguments from each language section.
12298 2002-07-29 Paul Eggert <eggert@twinsun.com>
12300 * doc/install.texi: Include copyright symbol in copyright notice.
12302 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12303 Replace with:
12304 (AM_MAKEINFOFLAGS): New macro.
12305 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12306 * Makefile.am (INSTALL): Use the new macros.
12307 Use -o rather than --output, since "missing" does not grok --output.
12309 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12311 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12312 comments do not always work. Never trust the exit status of
12313 `make -k'.
12315 2002-07-24 Kevin Ryde <user42@zip.com.au>
12317 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12318 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12320 2002-07-23 Paul Eggert <eggert@twinsun.com>
12322 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12323 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12324 apparently treats PATH="nonexistent" as if it contained ".".
12325 Bug reported by Stefan `Sec' Zehl.
12327 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12329 * doc/autoconf.texi (Limitations of Make): Mention the special
12330 handling of the obj/ directory by BSD make.
12332 2002-07-20 Kevin Ryde <user42@zip.com.au>
12334 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
12335 backslashes.
12337 2002-07-19 Akim Demaille <akim@epita.fr>

12340 (Programming in M4sh): Ethymology of M4sh.
12342 2002-07-19 Akim Demaille <akim@epita.fr>
12344 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
12346 2002-07-18 Akim Demaille <akim@epita.fr>
12348 Version 2.53b.
12350 2002-07-18 Akim Demaille <akim@epita.fr>
12352 * config/config.guess, config/config.sub: Update.
12354 2002-07-18 Akim Demaille <akim@epita.fr>
12356 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
12357 Automake's parts.
12359 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
12360 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
12361 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
12363 2002-07-18 Akim Demaille <akim@epita.fr>,
12364 Alexandre Duret-Lutz <duret_g@epita.fr>
12366 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
12367 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
12369 2002-07-17 Russ Allbery <rra@stanford.edu>
12371 * doc/autoconf.texi (Initializing configure): Clarify the
12372 description of the tarname default.
12374 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12376 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12377 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12378 latter was not run.
12380 2002-07-17 Akim Demaille <akim@epita.fr>
12382 * lib/Autom4te/General.pm (find_file): Browse the directories in
12383 the order they are given.
12385 2002-07-17 Akim Demaille <akim@epita.fr>

12388 * tests/wrapper.as: this.
12389 * tests/Makefile.am, configure.ac: Adjust.
12391 2002-07-17 Mark D. Roth <roth@feep.net>
12393 * configure.ac: Add --enable-site-macro-dir option.

12402 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
12403 macro directory, remove note that include path directories are
12404 used in reverse order, and document --prepend-include option.
12405 * lib/autom4te.in: Use --prepend-include instead of --include.
12406 * tests/wrapsh.in: Use --prepend-include instead of --include.
12408 2002-07-17 Akim Demaille <akim@epita.fr>
12410 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
12411 tarnames.

12414 2002-07-17 Akim Demaille <akim@epita.fr>

12451 2002-06-27 Paul Eggert <eggert@twinsun.com>
12453 * config/install-sh: Quote $src. Prefer || to test's -o option,
12454 as per "Limitations of Builtins".

12459 "Limitations of Builtins".
12461 2002-06-15 Paul Eggert <eggert@twinsun.com>
12463 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12464 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12465 so that we consistently test the just-built programs.
12466 * tests/wrappl.as: Likewise.
12468 2002-06-12 Paul Eggert <eggert@twinsun.com>
12470 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

12484 * doc/autoconf.texi: Add more dir entries.
12486 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12488 * bin/autom4te.in ($cache): Don't define using `$me', the name
12489 of the cache should not depend on the name under which autom4te
12490 was installed.
12492 2002-06-07 Akim Demaille <akim@epita.fr>
12494 * tests/tools.at (autoconf: forbidden tokens, basic)

12507 (AC_REPLACE_FNMATCH): this.
12508 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12509 AC_FUNC_FNMATCH_GNU.
12511 2002-06-07 Akim Demaille <akim@epita.fr>
12513 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
12514 Rosetta Stone for Unix.
12516 2002-06-07 Akim Demaille <akim@epita.fr>
12518 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12519 suggest m4_pattern_allow.
12520 Suggested by Adam J. Richter.
12522 2002-06-07 Akim Demaille <akim@epita.fr>
12524 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12525 ac_config_libobj_dir.
12526 (AC_CONFIG_LIBOBJ_DIR): New.
12527 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12528 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.

12534 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
12535 * tests/mktests.sh (ac_exclude_list): Don't check
12536 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
12538 2002-06-06 Paul Eggert <eggert@twinsun.com>
12540 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12541 if ln doesn't work.

12583 2002-05-22 Paul Eggert <eggert@twinsun.com>
12585 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12586 from the default list of compilers to try. Suggested by
12587 Kate Hedstrom.
12588 * NEWS: Document the above.
12589 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12591 2002-05-17 Paul Eggert <eggert@twinsun.com>
12593 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12594 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12595 This improves on an earlier suggestion by H. Peter Anvin.
12597 2002-05-16 Paul Eggert <eggert@twinsun.com>
12599 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12600 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12601 Both macros now accept an optional source-dir arg.
12602 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12604 * NEWS: Document this.
12605 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12607 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12608 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12609 not for GNU extensions; this undoes part of the 2000-11-03 change,
12610 reverting to 2.13-compatible behavior.
12611 Add new optional argument DIR.
12612 (AC_FUNC_FNMATCH_GNU): New macro.
12614 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12616 2002-05-08 Paul Eggert <eggert@twinsun.com>
12618 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12619 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12620 and it causes a 'test' syntax error if it fails.
12621 Bug reported by Stephen Gildea.
12623 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12624 If prototypes are supported, use them to check this at compile-time,
12625 instead of trying to check it at run-time. If we must do a run-time
12626 check, assume that setvbuf is standard when cross-compiling, as
12627 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12628 Bug reported by Paul D. Smith.
12630 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12631 argument specifying location of getloadavg.c. This removes a
12632 FIXME. This idea was taken from Jim Meyering's implementation in
12633 textutils.
12634 * doc/autoconf.texi (Particular Functions): Document this.
12635 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12636 that's what the code does; this fixes a bug reported by
12637 Paul D. Smith.
12639 2002-05-03 Akim Demaille <akim@epita.fr>
12641 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12642 autopoint instead of gettextize.
12643 ($uses_alocal): Rename as...
12644 ($uses_aclocal): this.
12645 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12646 Suggested by Bruno Haible.
12648 2002-05-03 Akim Demaille <akim@epita.fr>
12650 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12652 2002-04-29 Paul Eggert <eggert@twinsun.com>
12654 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12655 files to be 1 second older; just set them to be the same time.
12656 Also, sleep 1 second after the first aclocal, to work around
12657 problems with sub-second time stamps on the input files.
12659 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12661 * doc/autoconf.texi: Mention "set -e -x" lossage
12662 under node "Limitations of Builtins".
12664 2002-04-29 Akim Demaille <akim@epita.fr>
12666 * doc/install.texi: Better wording for setting variables when
12667 running configure.
12668 From Christian Cornelssen.
12670 2002-04-29 Akim Demaille <akim@epita.fr>
12672 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12673 of lack of $LINENO support, then the test will compare the $LINENO
12674 in testsuite vs. the lineno in the test file. This is wrong, of
12675 course.
12676 Be sure to protect it.
12677 Reported by Patrick Welche.
12679 2002-04-25 Akim Demaille <akim@epita.fr>
12681 * doc/autoconf.texi (Obsolete Macros): Typo.
12682 Reported by Vladimir Volovich.
12684 2002-04-25 Akim Demaille <akim@epita.fr>
12686 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12687 than some of the input files, hence, on the second run of aclocal,
12688 if some of its input are younger, make them older.
12689 Suggested by Paul Eggert.
12691 2002-04-25 Akim Demaille <akim@epita.fr>
12693 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12694 Thanks to Paul Eggert.
12696 2002-04-25 Akim Demaille <akim@epita.fr>
12698 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12699 and ac_subst_vars be sh variables containing the list of
12700 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12701 DEFAULT diversion.
12702 (_AC_INIT_PREPARE): Use them to log them.
12703 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12704 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12705 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12706 _AC_SUBST_FILES and _AC_SUBST_VARS.
12707 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12709 2002-04-24 Akim Demaille <akim@epita.fr>
12711 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12712 autoheader, so that automake does not complain about a missing
12713 config.h.in that was to be created.
12715 2002-04-23 Akim Demaille <akim@epita.fr>
12717 * bin/autoheader.in (parse_args): --warning takes an argument.
12718 Fixes PR/220.
12720 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12722 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
12723 and bb.out when cleaning up.
12725 2002-04-22 Akim Demaille <akim@epita.fr>

12739 2002-04-22 Akim Demaille <akim@epita.fr>
12741 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
12742 Fixes false failures on Darwin.

12767 Minor spelling and grammar fixes.
12769 * doc/autoconf.texi: Follow the outline suggested in the GNU
12770 Sample Texts sections of the Texinfo 4.2 manual. Most
12771 importantly, this makes sure that the copyright notices appear in
12772 all output formats. You probably need Texinfo 4.2 to generate
12773 the manual now.
12775 Fix some bugs when using "$@" when there might be zero positional

12824 Adjust Autoconf and Autotest.
12826 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12827 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12828 * lib/autotest/general.m4 (AT_INIT): Likewise.
12829 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

12876 (AC_CONFIG_LINKS): here.
12877 Adjust.
12878 Don't use the KILL diversion, as it kills spurious output, which
12879 results in failures being hidden.
12880 Use m4_defn where appropriate.

12882 after the second argument.
12883 Use m4_defn.
12884 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning

12893 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12894 aclocal.
12896 2002-04-03 Akim Demaille <akim@epita.fr>
12898 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
12899 (_AC_COMPILER_EXEEXT_REJECT): New.
12900 Also recognize *.bb and *.bbg as compilation byproducts.
12901 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12902 (_AC_COMPILER_OBJEXT): Use them.
12903 Fixes Debian #138666.
12905 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12907 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12909 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12910 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12911 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12912 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12913 (AC_C_CONST): Same.
12914 (AC_C_INLINE): Same.
12915 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12916 * doc/autoconf.texi, NEWS: Document.
12917 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12918 AC_C_CROSS.
12920 2002-04-02 Akim Demaille <akim@epita.fr>
12922 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
12923 _AS_MKDIR_P_PREPARE.
12925 2002-03-28 Kevin Ryde <user42@zip.com.au>
12927 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12928 to avoid versions of HP C which don't allow that.
12930 2002-03-27 Paul Eggert <eggert@twinsun.com>
12932 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12933 (AS_SHELL_SANITIZE): Invoke it.
12934 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12936 2002-03-26 Akim Demaille <akim@epita.fr>
12938 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12940 2002-03-26 Akim Demaille <akim@epita.fr>
12942 * doc/autoconf.texi (Introduction): The GNATS base moved.
12944 2002-03-25 Paul Eggert <eggert@twinsun.com>
12946 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12947 as POSIX requires, as it doesn't work with Zsh.
12948 * doc/autoconf.texi (Assignments): Document the problem.
12950 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12952 * doc/autoconf.texi (Limitations of Make): Mention more issue
12953 about VPATH, overriding of macros in sub-makes, and handling of
12954 SHELL.
12956 2002-03-21 Paul Eggert <eggert@twinsun.com>
12958 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12959 problem with here-document buffer boundaries.
12961 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12962 when reinvoking the shell, to work around problems with installers
12963 who put strange things like "cd" commands in their environments.
12965 2002-03-19 Akim Demaille <akim@epita.fr>
12967 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12968 From Aaron Ucko.
12970 2002-03-19 Akim Demaille <akim@epita.fr>
12972 * bin/autoscan.in (scan_file): Specify the location in `&used'
12973 invocations.
12974 From Nicolas Joly.
12976 2002-03-19 Akim Demaille <akim@epita.fr>
12978 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12979 From Nishio Futoshi.
12981 2002-03-19 Akim Demaille <akim@epita.fr>
12983 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12985 2002-03-18 Paul Eggert <eggert@twinsun.com>
12987 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12988 (Limitations of Usual Tools): Add mkdir section.
12990 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12991 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12992 back on AS_DIRNAME to compute prefixes otherwise; this is
12993 roughly what mkinstalldirs does. That way, we need not have
12994 our own filename disassembler. The old disassembler did not
12995 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12997 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12998 Create at_test_all by a series of assignments,
12999 not by a single assignment of a long string. The latter causes ksh
13000 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13001 presumably because of a buffer overrun.
13003 2002-03-14 Paul Eggert <eggert@twinsun.com>
13005 * lib/autotest/general.m4 (at_times_skip):
13006 Renamed from at_times. Now a boolean.
13007 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13008 says 'times: not found'.
13010 2002-03-14 Akim Demaille <akim@epita.fr>
13012 * bin/autoreconf.in (&study_gettextize): New.
13013 (&autoreconf): Handle newest gettextize.
13014 Rerun aclocal if needed.
13015 Suggested by Andreas Schwab.
13017 2002-03-13 Akim Demaille <akim@epita.fr>
13019 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13021 2002-03-13 Akim Demaille <akim@epita.fr>
13023 * doc/autoconf.texi (Header Portability): New.
13024 Add information about stdint.h and inttypes.h from Paul Eggert.
13026 2002-03-13 Akim Demaille <akim@epita.fr>
13028 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13029 -p'.
13030 From Bob Proulx.
13032 2002-03-12 Akim Demaille <akim@epita.fr>
13034 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13035 m4_require.
13037 2002-03-11 Andreas Schwab <schwab@suse.de>
13039 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13040 does not do it if --with-lispdir is given.
13042 2002-03-08 Akim Demaille <akim@epita.fr>
13044 Version 2.53.
13046 2002-03-08 Akim Demaille <akim@epita.fr>
13048 * doc/autoconf.texi (Subdirectories): Clarify that the
13049 subdirectory should exist.
13051 2002-03-08 Akim Demaille <akim@epita.fr>
13053 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13055 2002-03-08 Akim Demaille <akim@epita.fr>
13057 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13058 aliases the actual variables, and modifications of the former
13059 affect the latter.
13061 2002-03-08 Akim Demaille <akim@epita.fr>
13063 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13064 because of C-c: have m4 output in tmp files, then mv them.
13066 2002-03-08 Akim Demaille <akim@epita.fr>
13068 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13069 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13070 * bin/ifnames.in: Copyright update.
13072 2002-03-08 Akim Demaille <akim@epita.fr>
13074 * doc/autoconf.texi (Invoking autom4te): New.
13076 2002-03-05 Akim Demaille <akim@epita.fr>
13078 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13079 Kevin Ryde.
13081 2002-03-05 Akim Demaille <akim@epita.fr>
13083 Version 2.52i.
13085 2002-03-04 Akim Demaille <akim@epita.fr>
13087 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13088 * lib/autoconf/general.m4 (AC_INIT): More informative error
13089 message for LIBOBJ.
13091 2002-03-04 Akim Demaille <akim@epita.fr>
13093 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13094 parallel builds.
13096 2002-03-04 Akim Demaille <akim@epita.fr>
13098 * doc/autoconf.texi (Transforming Names): Equality between target
13099 and host is irrelevant.
13100 (Specifying Names, Canonicalizing): Remove all references to the
13101 backward compatibility hooks. Rather, collect them all into...
13102 (Hosts and Cross-Compilation): this new section.
13103 * doc/install.texi (System Type): Ditto.
13104 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13105 that `--host' implies cross-compilation.
13107 2002-03-04 Akim Demaille <akim@epita.fr>
13109 * doc/autoconf.texi (Evaluation Macros): New.
13110 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13111 useless.
13112 (_m4_foreach): Define the variant with immediate evaluation so
13113 that it contains exactly the items, not an expression which
13114 evaluation is the current item.
13115 (m4_re_string, m4_re_word): Don't over quote them.
13117 2002-03-04 Akim Demaille <akim@epita.fr>
13119 Instead of having stacking `shift's evaluated at the end, let
13120 `foreach' loops immediately evaluate them.
13122 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13123 $*. This is the n-th time I change my mind, but hopefully this is
13124 the last...
13125 (m4_lquote): New.
13126 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13127 efficient.
13128 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13129 it was only a hack for m4_text_wrap.
13130 (m4_car2): Remove, replaced by...
13131 (m4_cdr): New.
13132 (_m4_foreach): Adjust.
13133 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13134 m4_bpatsubst for clarification.
13136 2002-03-04 Akim Demaille <akim@epita.fr>
13138 * doc/autoconf.texi (Changequote is Evil): New.
13140 2002-03-03 Kevin Ryde <user42@zip.com.au>
13142 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
13143 on old systems like SunOS.

13165 From Akinori Musha.
13167 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
13169 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
13170 translate \r\n to \n.
13172 2002-02-07 Akim Demaille <akim@epita.fr>
13174 Version 2.52h.
13176 2002-02-07 Akim Demaille <akim@epita.fr>
13178 Fix Autoconf PR/209.
13179 Also reported by Frank Denis.
13181 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13183 2002-02-07 Akim Demaille <akim@epita.fr>
13185 Fix Autoconf PR/207:
13186 AC_PREFIX_PROGRAM fails with dashed program names
13188 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13189 variable when looking for the prefix program.
13190 Now it also works for shell variables.
13192 2002-02-07 Akim Demaille <akim@epita.fr>
13194 * doc/autoconf.texi (Limitations of Builtins): More about
13195 case/esac.

13200 case/esac, some shells don't support it.
13201 Reported by Zack Weinberg.
13202 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
13204 2002-02-06 Akim Demaille <akim@epita.fr>
13206 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
13207 sure not to introduce newlines in at_groups.
13208 * lib/autotest/Makefile.am (autotest.m4f): Typo.
13210 2002-02-06 Akim Demaille <akim@epita.fr>
13212 * tests/torture.at (Configuring subdirectories): Skip if aclocal
13213 is not available.
13215 2002-02-05 Paul Eggert <eggert@twinsun.com>
13217 * doc/autoconf.texi (Specific Compiler Characteristics):
13218 Describe HP-UX cc bug workaround more accurately.
13219 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13220 not unsigned long.
13221 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13222 cross-compilers, too. This undoes some of the most recent change
13223 to this file.
13225 2002-02-05 Akim Demaille <akim@epita.fr>
13227 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13228 to make sure they are up to date when `check' is run.

13232 * doc/autoconf.texi (Making testsuite Scripts): Document

13237 * lib/freeze.mk: New.
13239 2002-02-05 Akim Demaille <akim@epita.fr>
13241 Implement `autom4te --freeze'.
13243 * bin/autom4te.in (&freeze): New.
13244 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13245 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13247 2002-02-05 Akim Demaille <akim@epita.fr>
13249 * bin/autom4te.in (&parse_args): Implement `frozen files are
13250 optional are the sum of the previous files on the command line'.
13251 Also, pass `--reload-state=' on them, so...
13252 (handle_m4): don't.
13253 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13254 (M4sh): Rely on M4sugar.
13255 (Autotest, M4sh, M4sugar): Use frozen files.
13257 2002-01-31 Akim Demaille <akim@epita.fr>
13259 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13260 * doc/autoconf.texi (Initializing configure): Adjust.
13262 2002-01-30 Akim Demaille <akim@epita.fr>
13264 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13265 alphanumeric to `-' instead of `_'.
13267 2002-01-30 Akim Demaille <akim@epita.fr>
13269 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13270 for plain code, the other for cross-compilation code. The latter
13271 is now run with GCC only.
13272 * doc/autoconf.texi (Compilers and Preprocessors): New.
13274 2002-01-30 Akim Demaille <akim@epita.fr>
13276 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13277 values.
13278 * doc/autoconf.texi (Initializing configure): Explain how to
13279 change AC_INIT default values.
13281 2002-01-29 Akim Demaille <akim@epita.fr>
13283 * tests/torture.at (Configuring subdirectories): Use configure.in,
13284 so that aclocal 1.4 works.
13285 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13287 2002-01-28 Akim Demaille <akim@epita.fr>
13289 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13290 needs an argument.
13292 2002-01-28 Akim Demaille <akim@epita.fr>
13294 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13295 AUTOTEST_PATH *after* it was set.
13296 Don't put `.' in the PATH: the user should be precise and `./' if
13297 needed. In addition, given that the test suite does some `cd', if
13298 `.' is in the path, the `tested programs' sections will report
13299 programs found in the test suite's directory, while during the
13300 tests (performed in their own directory), these programs are no
13301 longer visible. In other words, the results is confusing and
13302 useless.
13303 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13305 2002-01-24 Akim Demaille <akim@epita.fr>

13316 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13317 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13318 Bourne. Use /bin/sh.
13319 From Andreas Buening.
13321 2002-01-24 Akim Demaille <akim@epita.fr>

13333 Automake.
13335 2002-01-24 Akim Demaille <akim@epita.fr>
13337 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13338 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13339 Reported by Geir Ove Myhr.
13341 2002-01-21 Akim Demaille <akim@epita.fr>
13343 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13345 2002-01-21 Akim Demaille <akim@epita.fr>
13347 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13348 message on invalid options.
13349 * bin/autom4te.in (parse_args): Don't use
13350 Autoconf::General::getopt with non valid options.
13352 2002-01-17 Jim Meyering <meyering@lucent.com>
13354 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13355 $ac_cv_exeext so we don't use an old, invalid, cached value.
13357 2002-01-11 Akim Demaille <akim@epita.fr>
13359 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13360 Meyering.

13362 limitation.
13363 (Particular Functions): Document AC_FUNC_STRNLEN.
13364 * lib/autoscan/functions: Adjust.
13366 2002-01-06 Akim Demaille <akim@epita.fr>
13368 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13369 package.m4, since is really depends upon configure.ac, not
13370 configure.
13371 * doc/autoconf.texi (testsuite Scripts): Adjust.
13372 * tests/Makefile.am (package.m4): New.
13373 EXTRA_DIST it since its a source.
13375 2002-01-06 Akim Demaille <akim@epita.fr>
13377 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13378 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13379 and PACKAGE_BUGREPORT from here...
13380 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13381 arguments.
13382 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13383 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13384 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13385 * tests/tools.at (autoheader): Adjust.
13386 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13388 2002-01-06 Akim Demaille <akim@epita.fr>
13390 * bin/autoscan.in (scan_file): Use `&used'.
13392 2002-01-03 Akim Demaille <akim@epita.fr>
13394 * doc/autoconf.texi (Output): Improved wording regarding use of
13395 AC_OUTPUT.
13396 From Olly Betts.
13398 2001-12-18 Kevin Ryde <user42@zip.com.au>
13400 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13401 sometimes needing writable input.
13403 2001-12-17 Jim Meyering <meyering@lucent.com>
13405 * doc/autoconf.texi (New Macros): Tweak wording.
13407 2001-12-14 Akim Demaille <akim@epita.fr>
13409 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13410 trailing files, don't apply `-rf' to files which might not be
13411 created by configure (core, core.*, and *.core), but just `rm -f'.
13412 Suggested by Jonathan Kamens.
13414 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13416 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13418 2001-12-14 Akim Demaille <akim@epita.fr>
13420 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13422 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13424 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13425 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13426 abs_srcdir, top_srcpath to abs_top_srcdir.
13427 (_AC_OUTPUT_FILES): Adjust.
13428 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13429 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13430 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13432 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13434 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13435 C/Fortran linking on HP/UX, by extracting the Fortran library
13436 search path from the LPATH line in the $F77 -v output.
13438 2001-12-12 Kevin Ryde <user42@zip.com.au>
13440 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13441 forbidden file descriptors table.
13443 2001-11-26 Akim Demaille <akim@epita.fr>
13445 * bin/autoscan.in (%c_keywords): Build it at top level.
13446 Map to 1 in order to simplify its uses.
13448 2001-11-26 Akim Demaille <akim@epita.fr>
13450 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13451 Remove $filepath, useless.
13452 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13453 variables, they are really part of the tokens.
13454 Split the input line on spaces and then look for tokens.
13455 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13456 because of `lex$U.$(OBJEXT)'.
13457 (&scan_files): Use "@list" instead of join.
13458 * doc/Makefile.am (CLEANFILES): Add *.fns.
13460 2001-11-26 Akim Demaille <akim@epita.fr>
13462 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13463 Remove, replaced by...
13464 * tests/wrappl.in: Be common for all the Perl executables.
13465 In particular autoscan and autoheader want -I.
13466 * configure.ac: Adjust.
13467 * lib/autoscan/headers: errno.h is portable.
13469 2001-11-26 Akim Demaille <akim@epita.fr>
13471 * bin/autoscan.in (used): New.
13472 Use it.
13474 2001-11-26 Akim Demaille <akim@epita.fr>
13476 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13477 directives.
13478 (&scan_sh_file): Remove a duplicate pattern.
13479 (&check_configure_ac): Use long options.
13480 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13482 2001-11-26 Akim Demaille <akim@epita.fr>
13484 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13485 Before, having a line containing the opening of a multi line
13486 comment made the whole line be ignored.
13488 2001-11-26 Akim Demaille <akim@epita.fr>
13490 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13491 (testsuite Scripts): Be one of its subsection.
13492 (Autotest Logs): New.
13494 2001-11-26 Akim Demaille <akim@epita.fr>
13496 Test groups are now run two directories deeper.
13498 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13499 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13500 at_top_builddir.
13501 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13502 top_srcdir, builddir and top_builddir.
13503 Use `at_*dir' relatively to the directory containing the
13504 suite, use `*dir' when relatively to the current group dir.
13506 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13508 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13509 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13510 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13511 spelling errors.
13513 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13515 * doc/autoconf.texi (Using System Type): Add an example of `case
13516 $host' usage so people quit using `case $target' everywhere.
13518 2001-11-22 Akim Demaille <akim@epita.fr>
13520 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13521 spotted by Jim Meyering.
13523 2001-11-16 Paul Eggert <eggert@twinsun.com>
13525 This patch implements a `long double' suggestion by Oliver Kiddle.
13527 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13528 static, to catch errors if the value isn't known at compile-time
13529 and the compiler supports dynamic arrays. Change its name from
13530 `_array_' to `test_array' to avoid potential name clashes.
13531 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13532 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13533 better than double. Catch a bug in GCC 2.95.2 x86.
13534 * doc/autoconf.texi (C Compiler): Document the above.
13535 * NEWS: Likewise.
13537 2001-11-13 Akim Demaille <akim@epita.fr>
13539 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13540 hand.
13541 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13543 2001-11-13 Akim Demaille <akim@epita.fr>
13545 * lib/autotest/general.m4 (AT_INIT): After having run the test
13546 group, go back to the initial directory, not to at_suite_dir.
13548 2001-11-13 Akim Demaille <akim@epita.fr>
13550 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13551 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13552 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13553 option.
13554 (AT_CHECK_CONFIGURE): Use absolute paths.
13555 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13556 The problem is still the old one: there is no means in M4 (that I
13557 know about) to create a defining macro, because there is no means
13558 to create `$1' etc., therefore, the defining macro ``swallows''
13559 all the arguments meant to the defined macro.
13561 2001-11-13 Akim Demaille <akim@epita.fr>
13563 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13564 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13565 configure.ac.
13566 * tests/aclocal.m4: Remove, as it is no longer used.
13568 2001-11-13 Akim Demaille <akim@epita.fr>
13570 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13571 variable names when referring to a single test group, or to
13572 `suite' when referring to the whole test suite.
13573 `at_last_test' is removed: m4 compute at_format itself.
13574 (at_stdout, at_stder1, at_stderr): New variables.
13575 (AT_CHECK): Use them.
13577 2001-11-13 Akim Demaille <akim@epita.fr>
13579 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13580 in PATH.
13581 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13582 Do it as soon as a test fails, don't wait till the end of the test
13583 suite.
13584 Don't remove $as_me.[0-9]*, since these files no longer exist.
13586 2001-11-13 Akim Demaille <akim@epita.fr>
13588 * tests/tools.at: Use absolute paths, since we are no longer run
13589 in place.
13591 2001-11-13 Akim Demaille <akim@epita.fr>
13593 Now that tests are running in their own private dir, there is no
13594 need to list the files to remove at the end of tests groups.
13596 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13597 (AT_data_files, at_data_files): Remove.
13598 (AT_CLEANUP, AT_DATA): Simplify.
13599 (AT_INIT): Adjust.
13600 Remove the group dir if !debug && !failed.
13601 * tests/atspecific.m4: Adjust.
13603 2001-11-13 Akim Demaille <akim@epita.fr>
13605 Start a new layout for Autotest: `testsuite' creates
13606 `testsuite.dir' in which the at-check-line etc. files are to be
13607 found, and `testsuite.dir/003' where the test group 3 is run.
13609 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13610 at_check_line_file, at_format, at_test_normalized, at_group_dir
13611 are new variables.
13612 Create the directories.
13613 Use absolute paths for at- files.
13614 (AT_CHECK): Adjust.
13616 2001-11-11 Michael Matz <matz@kde.org>
13618 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13619 (m4_car2): New.
13620 (m4_car): Properly quote arguments.
13622 2001-11-13 Akim Demaille <akim@epita.fr>
13624 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13625 with stricter rules on LIBOBJS.
13627 2001-11-12 Paul Eggert <eggert@twinsun.com>
13629 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13630 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13631 __PROTOTYPES too.
13633 2001-11-12 Akim Demaille <akim@epita.fr>
13635 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13637 2001-11-12 Akim Demaille <akim@epita.fr>
13639 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13640 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13641 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13642 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13643 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13644 specify to what the macro should be defined (typically to 1).
13646 2001-11-12 Akim Demaille <akim@epita.fr>
13648 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13649 From Jim Meyering.
13651 2001-11-12 Akim Demaille <akim@epita.fr>
13653 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13654 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13655 definition used by Automake where LEX is +/- "${missing} lex" and
13656 `missing' itself contains variables.
13658 2001-11-12 Akim Demaille <akim@epita.fr>
13660 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13661 Now that M4sh pushes BODY, the comments were output at the end of
13662 the test suites.
13664 2001-11-08 Akim Demaille <akim@epita.fr>
13666 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13667 that we can trace macros from aclocal.m4.
13668 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13669 obsoleted, and redirect to the former anyway.
13670 Reported by Ralf Corsepius.
13672 2001-11-08 Akim Demaille <akim@epita.fr>
13674 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13675 processed only if present.
13676 * tests/torture.at (Configuring subdirectories): Use autoreconf
13677 instead of successive calls to autoconf.
13678 Add a nonexistent subdirectory to exercise the patch above.
13679 Reported by Ralf Corsepius.
13681 2001-11-08 Kevin Ryde <user42@zip.com.au>
13683 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13684 doesn't accept .S files.
13686 2001-11-07 Akim Demaille <akim@epita.fr>
13688 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13689 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13690 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13691 * bin/autom4te.in (warn_forbidden): New.
13692 (handle_output): Use it.
13693 Read m4_pattern_forbid with messages.
13695 2001-11-05 Akim Demaille <akim@epita.fr>
13697 * bin/autom4te.in (--normalize): Remove.
13698 * lib/autom4te.in: Adjust.
13700 2001-11-05 Akim Demaille <akim@epita.fr>
13702 * tests/Makefile.am (testsuite): Rename this target as...
13703 ($(TESTSUITE)): this.
13704 From Nicolas Joly.
13706 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13708 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13709 the --prefix option, also remove it's argument.
13711 2001-11-05 Akim Demaille <akim@epita.fr>
13713 * doc/autoconf.texi (testsuite Invocation): Update.
13714 (Writing testsuite.at): Update.
13716 2001-11-03 Akim Demaille <akim@epita.fr>
13718 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13720 2001-11-03 Akim Demaille <akim@epita.fr>
13722 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13723 (&file_name_is_absolute): New, wrappers around routines from
13724 File::Spec.
13725 Use and export them.
13726 (&find_configure_ac): Optionally take a directory where to look at.
13727 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13728 the arguments.
13729 Default @ARGV to `.', not find_configure_ac.
13730 (&autoreconf): Argument is a directory.
13731 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13732 * doc/autoconf.texi (autoreconf Invocation): Update.
13734 2001-11-03 Akim Demaille <akim@epita.fr>
13736 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13737 (@export_forward_subs): New.
13738 Add basename, dirname, and fileparse.
13739 (@EXPORT): Adjust.
13740 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13741 Don't look for aclocal flags if we already know aclocal is not
13742 used.
13743 Move aclocal.m4t only if it exists.
13744 Reported by Ezra Peisach.
13746 2001-11-03 Akim Demaille <akim@epita.fr>
13748 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13749 passed on command line, defaulting to ./configure.ac if present.
13750 (&maybe_autoreconf, File::Find): Remove, unused.
13751 (&autoreconf): If autoconf is not used, don't try to trace.
13753 2001-11-02 Akim Demaille <akim@epita.fr>
13755 * configure.ac: Bump to 2.52g.
13757 2001-11-02 Akim Demaille <akim@epita.fr>
13759 Version 2.52f.
13761 2001-11-02 Akim Demaille <akim@epita.fr>
13763 * config/config.guess, config/config.sub, doc/standards.texi:
13764 * config/lispdir.m4: Update from masters.
13765 * configure.ac: Bump to 2.52f.
13767 2001-11-02 Akim Demaille <akim@epita.fr>
13769 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13770 Don't run aclocal when aclocal.m4 is not from aclocal.
13771 From Ezra Peisach.
13772 Don't run libtoolize and gettextize if --install is not given.
13774 2001-11-01 Paul Eggert <eggert@twinsun.com>
13776 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13777 be invoked before _AS_LINENO_PREPARE.
13778 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13779 than character ranges.
13781 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13782 invoking AS_BASENAME. Set the locale variables to 'C' if
13783 possible, as POSIX requires this to get the traditional
13784 behavior.
13785 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13787 2001-10-31 Paul Eggert <eggert@twinsun.com>
13789 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13790 with {}, as that triggers a bug in Bash 2.05.
13792 (_AS_LINENO_PREPARE): Use Sed rather than
13793 Awk. Fix the sed prepass to work even if there are multiple
13794 instances of $LINENO on the same line. Do not substitute for
13795 other variables like $LINENOT. Do not check file dates; such a
13796 check is unreliable on sufficiently fast machines, and removing
13797 the check makes the code simpler and more reliable. Check for
13798 output and chmod failures.
13800 * doc/autoconf.texi (Special Shell Variables): Document
13801 the above.
13803 2001-10-31 Akim Demaille <akim@epita.fr>
13805 * tests/Makefile.am (atconfig): Remove this target, Automake
13806 handles it now.
13808 2001-10-31 Akim Demaille <akim@epita.fr>
13810 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13811 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13812 provided, while it is optional.
13813 * configure.ac: Adjust.
13815 2001-10-26 Paul Eggert <eggert@twinsun.com>
13817 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13818 lib/Autom4te/Struct.pm:
13819 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13820 with 5.005_02.
13822 * doc/autoconf.texi (Special Shell Variables): Document some
13823 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13825 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13826 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13827 eval $LINENO is not portable in practice.
13829 2001-10-24 Akim Demaille <akim@epita.fr>
13831 * lib/Autom4te/General.pm (backname): New.
13833 2001-10-24 Akim Demaille <akim@epita.fr>
13835 * m4/: Remove, merged into...
13836 * config/: here.
13838 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13840 * doc/autoconf.texi (Shellology): Mention the problems with bash
13841 2.05's use of ANSI quoting in its `set' builtin.
13843 2001-10-22 Paul Eggert <eggert@twinsun.com>
13845 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13846 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13847 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13848 POSIX decided to standardize on the int flavor of strerror_r.
13849 Always do char* test, as there's no reason not to.

14300 * lib/autoconf/autotest.m4: Create `package.m4'.
14301 * tests/Makefile.am (package.m4): Remove.
14303 2001-09-22 Akim Demaille <akim@epita.fr>
14305 Rely on `$LINENO' when possible instead of `__oline__'.
14307 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14308 `$LINENO' support replacement when not supported.
14309 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14310 them explicitly to be sure they are not output before this section
14311 (via m4_require). Cosmetic only.
14312 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14313 * lib/autoconf/programs.m4: Replace all the occurrences of
14314 `__oline__' with `$LINENO'.
14315 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
14317 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14319 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14320 character (u: -> ue) in a code comment.
14321 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14322 it works.
14324 2001-09-21 Akim Demaille <akim@epita.fr>
14326 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14327 Suggested by Jim Meyering.
14329 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14331 * lib/autoconf/programs.m4: Use extensions listed in
14332 $ac_executable_extensions when looking for programs.
14334 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14336 * lib/autoconf/general.m4: Fix a small Englisho.
14337 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14338 setting up ac_dir_suffix and ac_top_builddir.
14339 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14341 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14343 * doc/autoconf.texi (File System Conventions): Clarify the use of
14344 PATH_SEPARATOR.
14345 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14346 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14347 be used instead of ':'.
14348 * lib/autotest/general.m4: Replace occurrences of ':' in
14349 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14351 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14353 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14354 arguments. Fixed a typo.
14356 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14358 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14359 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14361 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14363 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14364 * bin/autoupdate.in: Ditto.
14365 * bin/autoheader.in: Reworded a few comments.
14366 * bin/autoconf.in: Reworded help text for a few options.
14367 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14368 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14370 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14372 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14373 already have $file). Set output files to binary mode (helps avoid
14374 CR issues on DOSish systems).
14376 2001-09-19 Akim Demaille <akim@epita.fr>
14378 * lib/autotest/general.m4: Englishoes.
14379 From Tim Van Holder and Alexey Mahotkin.
14381 2001-09-18 Paul Eggert <eggert@twinsun.com>
14383 * doc/autoconf.texi (Common Shell Constructs): New node,
14384 documenting AS_DIRNAME.
14385 (Limitations of Usual Tools): Refer to it when discussing dirname.
14386 Also, update discussion of POSIX standard to reflect latest draft.
14388 * lib/autoconf/c.m4:
14389 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14391 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14392 Do not pass a first argument with leading '-'
14393 to expr, by parenthesizing initial integers that might be negative.
14395 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14396 now merely checks whether it is an error to pass an argument
14397 to getpgrp.
14399 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14400 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14401 whether it is a (compile-time) error to pass an argument to
14402 getpgrp. This simpler test supports the revised documentation,
14403 and is all that AC_FUNC_GETPGRP's users really need.
14405 2001-09-18 Akim Demaille <akim@epita.fr>
14407 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14409 2001-09-18 Akim Demaille <akim@epita.fr>
14411 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14412 `{}'.
14413 * lib/autotest/general.m4 (AT_INIT): Adjust.
14415 2001-09-18 Paul Wagland <paul@wagland.net>
14417 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14418 correctly.
14419 Add test for AS_BASENAME.
14420 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14421 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14422 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14423 * tests/base.at: Fixed the expected responses. The old ones were
14424 one line out...
14425 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14426 the documentation claims it should (and how it behaved in 2.13).
14428 2001-09-18 Akim Demaille <akim@epita.fr>
14430 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14431 the AC_CONFIG_COMMANDS invocation.
14432 This also solves the name clash problems.
14433 Don't set the package's ID.
14434 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14435 No longer to be shipped.
14436 (version.in): Remove.
14437 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14438 * lib/autoconf/status.m4: Adjust.
14439 Use `m4_PACKAGE_STRING'.
14440 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14441 the only optional argument is the name of the test suite.
14442 Expect `package.m4' to define the package signature.
14443 * lib/autom4te.in (Autotest): Add `package.m4?'.
14444 * tests/Makefile.am (package.m4): New.
14445 * tests/suite.at: ifnames is a victim.
14447 2001-09-18 Akim Demaille <akim@epita.fr>
14449 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14450 AC_LIBSOURCE, AC_CONFIG_FILES.
14451 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14452 program version string doesn't match the package's.
14453 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14454 after `(cached)'.
14456 2001-09-17 Paul Eggert <eggert@twinsun.com>
14458 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14459 Allow expression to return any value that can fit into unsigned long
14460 (not int, as before). Check for output errors.
14462 2001-09-17 Bruno Haible <haible@ilog.fr>
14464 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14465 Always include <stdio.h> and <stdlib.h>. Evaluate
14466 the expression in an extra function before these includes. Call
14467 fprintf "%d" only after ensuring the argument is of type 'int'.
14468 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14470 2001-09-17 Paul Eggert <eggert@twinsun.com>
14472 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14473 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14474 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14475 when they don't exist.
14477 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14478 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14479 need it.
14481 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14482 version with the version used by fileutils 4.1, except use
14483 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14484 we don't need it.
14486 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14488 2001-09-13 Akim Demaille <akim@epita.fr>
14490 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14491 _first_.
14492 Reported by Gerrit P. Haase.
14494 2001-09-13 Akim Demaille <akim@epita.fr>
14496 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14497 m4_defn'ing is valid.

14503 Use it.

14511 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14512 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14513 Likewise.
14514 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14515 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14516 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14517 AT_tests_all for consistency.
14518 Set at_victims.
14519 (AT_VICTIMS): Similar to AT_KEYWORDS.
14520 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14522 2001-09-13 Akim Demaille <akim@epita.fr>
14524 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14526 2001-09-13 Akim Demaille <akim@epita.fr>
14528 * lib/autotest/general.m4 (AT_INIT): Create and remove
14529 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14530 test suites can cohabit.
14532 2001-09-13 Akim Demaille <akim@epita.fr>
14534 * tests/mktests.sh: Don't output banners for empty test files.
14536 2001-09-13 Akim Demaille <akim@epita.fr>
14538 Test suites can be run independently of configure.
14540 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
14541 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.
14542 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust: AC_SUBST

14576 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
14577 No longer fill the HELP diversion.
14578 (AT_CLEANUP): Use them.
14579 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
14580 (m4_list_append): Remove.
14582 Spread a few keywords in the Autoconf test suite.
14584 2001-09-10 Akim Demaille <akim@epita.fr>
14586 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14602 2001-09-07 Akim Demaille <akim@epita.fr>
14604 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5

14606 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
14607 related variables into `at_package_*'.

14619 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
14620 in addition, it introduces useless differences in logs.
14621 (AT_INIT): Let atconfig and atlocal be both optional.
14622 Adjust PATH computation.
14623 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

14634 From Uwe Seimet.
14636 2001-09-05 Akim Demaille <akim@epita.fr>
14638 * bin/autom4te.in: --language is -l, not -s.
14640 2001-09-05 Akim Demaille <akim@epita.fr>
14642 Be ready to handle filenames as stupid as `dnl.at', for if even
14643 the maintainer is dumb enough to do that...
14645 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14646 excellence in M4 quotation: consider `__file__' is active.
14648 And BTW, when invoking m4, pass the --include in the right order:

14674 2001-09-05 Akim Demaille <akim@epita.fr>

14679 New, extracted from main.
14680 Use IO::File wherever possible.
14681 (input.m4): Be constant, use -I instead of hard coding $tmp.
14682 Therefore be a quoted heredoc.
14683 Don't invoke `_au_disable', since ac was not loaded, but just
14684 `unm4.m4'.
14686 2001-08-31 Akim Demaille <akim@epita.fr>
14688 Version 2.52d.

14709 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
14711 2001-08-31 Akim Demaille <akim@epita.fr>
14713 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14714 (testsuite Scripts): There is no such thing as `atconfig.in'.
14715 And actually one diagram is missing: test suite runtime.
14717 2001-08-31 Akim Demaille <akim@epita.fr>
14719 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14720 inverse order.
14722 2001-08-31 Akim Demaille <akim@epita.fr>
14724 * bin/autoupdate.in (@include): `installcheck' revealed the path
14725 to m4sugar was lacking!
14727 2001-08-31 Akim Demaille <akim@epita.fr>
14729 * man/Makefile.am (.x.1): We really have to pass
14730 autom4te_perllibdir.
14732 2001-08-31 Akim Demaille <akim@epita.fr>
14734 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14735 debug scripts, in particular passing explicitly listed tests to
14736 run is stupid.
14738 2001-08-31 Akim Demaille <akim@epita.fr>
14740 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14741 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14742 Use directly autom4te, not autoconf.
14743 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.

14756 * bin/autom4te.in (&parse_args): Die on unknown languages.
14757 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14758 need for autoconf.
14759 Promote --include over --macrodir and other obsolete options.
14761 2001-08-31 Akim Demaille <akim@epita.fr>
14763 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
14764 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
14765 * bin/autom4te.in ($autoconf): Pass --force.
14766 `print $out' doesn't print `$_' but `$out'.
14767 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14768 (autoheader): Pass --force since the test suite goes too fast for
14769 the time stamps.
14770 Adjust to the new autoheader messages.
14772 2001-08-31 Akim Demaille <akim@epita.fr>
14774 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14775 Check the completeness of the #template.
14776 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
14777 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
14778 invocation.
14780 2001-08-31 Akim Demaille <akim@epita.fr>
14782 * lib/Autom4te/General.pm (&find_file, &update_file): New.
14783 * bin/autoupdate.in, bin/autoheader.in: Adjust.
14784 Drop AC_MACRODIR dead for real.
14785 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14786 `autoheader: `config.hin' is created'.
14787 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14789 2001-08-31 Akim Demaille <akim@epita.fr>
14791 * bin/autoheader.in: Rewrite in Perl.
14792 * tests/autoheader: Adjust.
14794 2001-08-31 Akim Demaille <akim@epita.fr>
14796 * bin/autoconf.in (--include, -I): New option.
14797 Map --localdir, --autoconf-dir onto it.
14798 Forward autom4te's options instead of interpreting them.
14799 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14800 There is no such envvar since the inception of autom4te.cfg.
14801 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14802 * bin/autoupdate.in: Adjust, and perform more control.
14803 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
14804 * tests/autoconf: Dittowise.
14806 2001-08-31 Akim Demaille <akim@epita.fr>
14808 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14809 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14810 optionally `FILE'.
14811 Use -e, not -f, since /dev/null for instance is OK.
14812 (&parse_args): Adjust.
14813 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14815 2001-08-31 Akim Demaille <akim@epita.fr>
14817 * configure.ac: Also find tested executables in bin.
14818 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14819 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14820 installed peer executables, only PATH is allowed to resolve it.
14821 Pass `autoconf_dir' via options, not via invisible envvars.
14822 * lib/Autom4te/General.pm (&find_peer): Remove.
14823 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14824 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14825 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14826 find the executables for it.
14827 * tests/Makefile.am: Major cleanup. Too lazy to document...
14828 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14829 We only need PERL.
14830 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14831 indeed related to running the test suite, while passing
14832 --autoconf-dir and others is related to running non installed
14833 Autoconf executables. So don't do that, leave it to...
14834 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14835 * tests/autoscan: New.
14836 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14837 refer to library files: rely on --language.
14839 2001-08-29 Akim Demaille <akim@epita.fr>
14841 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
14842 s/--set/--language/.
14844 2001-08-29 Akim Demaille <akim@epita.fr>
14846 * doc/autoconf.texi: Strip the @nodes.
14847 Suggested by Paul Eggert.

14850 2001-08-29 Akim Demaille <akim@epita.fr>
14852 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14853 Suggested by Paul Eggert.
14855 2001-08-29 Akim Demaille <akim@epita.fr>
14857 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14858 download in a tmp dir.
14860 2001-08-29 Akim Demaille <akim@epita.fr>
14862 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
14863 case insensitive OSes out there :(

14873 (&parse_args): Support --mode, --set, and --melt.
14874 * bin/autoconf.in: Simplify and adjust.
14875 * tests/Makefile.am (AUTOMAKE): Use --set.
14876 * tests/atlocal.in: Adjust.
14877 * BUGS: distcheck and check are weak.
14879 2001-08-29 Akim Demaille <akim@epita.fr>
14881 * lib/autotest/general.m4: Use
14882 foo=`(command) 2>/dev/null`
14883 not
14884 foo=`command` 2>/dev/null
14885 (at-devnull): Rename as...
14886 (AT-devnull): this.
14887 (--clean): Remove AT-* files too.
14888 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14889 Reported by Nicolas Joly.

14905 Support test ranges as arguments to the testsuite.
14906 Have -e imply -d as the help text suggested.
14908 2001-08-27 Akim Demaille <akim@epita.fr>
14910 * Makefile.maint: Formatting changes.
14911 (do-po-update, po-update, cvs-update, update): New targets.

14923 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14924 Support `VAR=VAL' as arguments.

14930 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
14931 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
14932 first the build dirs, then the src dirs.

14944 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14945 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14946 readable.
14947 Adjust callers.
14948 * doc/autoconf.texi (Configuration Actions): Document the vars
14949 available in commands.
14950 Emphasize the risks of collisions in init-cmds.

14981 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
14982 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
14983 -> ac_dir).
14984 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
14985 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

15013 (AMTAR): Help automake define it.

15015 needed, 1.5 can have a macro and a target with the same name.
15016 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15017 * m4/strip.m4: New.

15030 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
15031 Adjust callers.
15032 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15033 the name of the directory they're in, instead of the filename,
15034 since version.m4 is now in m4sugar, but m4_acversion must not be
15035 classified as an Autoconf macro.
15036 ($input_m4): Don't qualify the path to m4sugar.
15037 Rather, pass autoconf_dir to m4.
15038 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15039 * tests/suite.at: Require 2.52c.
15041 2001-08-27 Akim Demaille <akim@epita.fr>

15055 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15056 for config.status'.
15057 Open the log as soon as possible.
15058 Use the same log introduction as configure's.
15060 2001-08-22 Paul Eggert <eggert@twinsun.com>
15062 * doc/autoconf.texi (Indices): New node.
15063 Move indices out of the top level menu and into this submenu.
15065 2001-08-22 Akim Demaille <akim@epita.fr>
15067 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
15068 AC_TRY_COMMAND.
15069 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
15071 2001-08-22 Akim Demaille <akim@epita.fr>
15073 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

15110 * configure.ac (AT_CONFIG): Fix the path.
15111 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
15112 can be used.
15114 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
15116 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
15117 program with AC_LANG_PROGRAM before feeding it to
15118 AC_COMPILE_IFELSE. Cleanup grep usage.
15120 2001-08-20 Akim Demaille <akim@epita.fr>
15122 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15123 * NEWS, README, README-alpha, TODO, tests/README: This package is
15124 `Autoconf', not `autoconf' (the executable).
15126 2001-08-20 Akim Demaille <akim@epita.fr>
15128 Info readers seem to need `Index' in the index node title :(
15130 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15131 simplified index node names.
15133 2001-08-20 Akim Demaille <akim@epita.fr>
15135 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
15136 arguments are not literals.
15137 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
15138 Specify the output variables, and macros defined.
15140 2001-08-20 Akim Demaille <akim@epita.fr>
15142 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
15143 (Examining Syntax) <AC_TRY_COMPILE>
15144 (Examining Libraries) <AC_TRY_LINK>
15145 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
15146 their arguments.
15147 Reported by Werner Lemberg.
15149 2001-08-20 Akim Demaille <akim@epita.fr>
15151 * lib/autotest/general.m4 (AT_INIT): Compute top_builddir,
15152 top_srcdir and srcdir from at_topbuild_2_topsrc and at_testdir.
15153 Load atlocal late enough to dump it in the log.

15164 2001-08-20 Akim Demaille <akim@epita.fr>
15166 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
15167 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
15168 test suite lives.
15169 Create `atconfig' automagically.
15170 Configure atlocal.in if present.
15171 * tests/atconfig.in: Remove.
15172 * tests/atlocal.in: New.
15173 * tests/Makefile.am: Adjust.
15175 2001-08-20 Akim Demaille <akim@epita.fr>
15177 Huh!?!?! There are still some user EOF tags used, which prevents
15178 their use in AC_CONFIG_COMMANDS for instance...
15180 * lib/autoconf/general.m4, lib/autoconf/specific.m4,

15262 * doc/autoconf.texi: Work around Texinfo buglets.
15263 (Transformation Rules): One example is enough, users are expected
15264 to have their brains on. And BTW, use DESTDIR.
15265 (dvar): New macro. Use it.

15317 (cvs-dist): depends upon it.
15319 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15321 * tests/Makefile.am: Use a clean-local rule to remove
15322 autom4te.cache (it's a directory, not a file.
15323 * Makefile.am: Ditto (but maintainer-clean-local).
15325 2001-08-15 Akim Demaille <akim@epita.fr>
15327 * bin/autom4te.in (@m4_warning): New.
15328 (&handle_m4): Use it.
15329 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15330 warnings are issued at each run.
15331 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15332 is in the src tree.
15334 2001-08-15 Akim Demaille <akim@epita.fr>

15337 don't waste time running `autoupdate --version' works.
15338 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15340 2001-08-13 Akim Demaille <akim@epita.fr>

15399 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15401 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15402 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15403 * doc/autoconf.texi (C Compiler Characteristics): Update
15404 documentation for AC_C_BIGENDIAN.
15406 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15408 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15409 magic values from an object file when cross-compiling.
15410 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15412 2001-08-10 Akim Demaille <akim@epita.fr>
15414 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15415 effects.
15416 Suggested by Russ Allbery.
15418 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15420 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15421 current $prefix to the sub-configures.
15423 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15425 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15426 extension (needed on BeOS). Reported by Guido van Rossum.
15428 2001-08-09 Akim Demaille <akim@epita.fr>
15430 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15432 2001-08-07 Akim Demaille <akim@epita.fr>
15434 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15435 removed.
15436 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15437 No need to remove the files before and after the each test, before
15438 each test and at the end of the suite is enough.
15439 Display only the children `times', not the shell's.
15440 If the test failed or was skipped, at-times is not available.
15442 2001-08-07 Akim Demaille <akim@epita.fr>
15444 Always produce testsuite.log, including when there are no
15445 failures. This helps getting information on skipped tests, and
15446 duration of the tests. Err, implement the latter btw.
15448 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15449 Dump information on the first run of each test.
15450 (AT_CLEANUP): Create `at-times' containing the duration of the
15451 test group.
15453 2001-08-07 Akim Demaille <akim@epita.fr>
15455 The use of `dumpstat' revealed that `len' was used although it
15456 should not. m4_text_wrap was using it, but in the Autoconf world
15457 where it is legal. Hence (i) test M4sh in its own world, not
15458 Autoconf's, and (ii), ahem, fix the bug :)
15460 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15461 does not like `' instead of [].
15462 (AT_INIT): Forbid `^_?AT_'.
15463 And don't output such tokens.
15464 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15465 `script.as', and `autom4te.cache'.
15466 Remove `empty' and `macro' which are no longer used.
15467 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15468 * tests/m4sugar.at: Use it.
15469 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15471 2001-08-07 Akim Demaille <akim@epita.fr>
15473 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15475 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15477 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15479 2001-08-04 Akim Demaille <akim@epita.fr>
15481 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15482 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15483 AC_TRY_LINK.
15484 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15485 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15486 (AC_F77_MAIN): Likewise.
15488 2001-08-04 Akim Demaille <akim@epita.fr>
15490 Don't rely on M4sugar outputting the patterns in files, since we
15491 might process the output _without_ running m4, hence without these
15492 files.
15494 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15495 * bin/autom4te.in (@Request::includes): Remove, unused.
15496 (@Request::source): Rename as...
15497 (@Request::input): this.
15498 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15499 (&handle_output): Fetch the patterns from the traces.
15500 `$forbidden' and `$allowed' are constant: use m//o.
15501 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15502 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15504 2001-08-04 Akim Demaille <akim@epita.fr>
15506 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15507 autoconf', i.e., in addition to caching traces, cache the output.
15509 * bin/autom4te.in (Request::cache): Rename as...
15510 (Request::id): this.
15511 ($cache, $icache, $tcache, $ocache): New.
15512 (&handle_m4): Save M4 output in the cache instead of $tmp.
15513 (&handle_output): Adjust.
15514 (&up_to_date_p): Check that the output cache is up to date too.
15515 (top level): Run `&handle_m4' iff force or the cache is invalid.
15516 Run `&handle_output' if the output cache is more recent.
15518 2001-08-04 Akim Demaille <akim@epita.fr>
15520 * bin/autom4te.in ($force): New.
15521 (&parse_args, &print_usage): -f, --force is a new option.
15522 (&handle_output): CPP directives might have spaces after `#'.
15523 (&parse_args): The first file only can be frozen.
15525 2001-08-04 Akim Demaille <akim@epita.fr>
15527 Don't let autom4te compute the `include' traces several times:
15528 first check that the trace cache file is up to date, and then
15529 compare its timestamp with that of the output.
15531 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15532 the preamble. Don't require 5.005 as Autom4te::General does it,
15533 and better yet (use `use', not `require'!).
15534 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15535 Class::Struct as Autom4te::Struct.
15536 * lib/Autom4te/General.pm (File::stat): Use it.
15537 (&mtime): New, export it.
15538 * bin/autom4te.in: Use it.
15539 Declare `$req' is invalid if it is outdated.
15540 Don't declare it valid before saving it if something went wrong.
15542 2001-08-04 Akim Demaille <akim@epita.fr>
15544 Autom4te shall not encode Autoconf data, and preselecting traces
15545 must be proposed to the users.
15547 * bin/autom4te.in (@required_trace): Remove.
15548 (@preselect): New.
15549 (&parse_args, &print_usage): -p, --preselect is a new option.
15550 (&up_to_date_p): Adjust.
15551 * bin/autoconf.in: Preselect some Autoconf macros.
15553 2001-08-04 Akim Demaille <akim@epita.fr>
15555 * tests/tools.at (autoconf --trace: user macros): Check traces on
15556 macros invoked without arguments, and macros invoked with multiple
15557 lines arguments.
15559 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15561 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15562 arguments.
15564 2001-08-03 Akim Demaille <akim@epita.fr>
15566 * bin/autoconf.in ($@): Work around the usual sh bug.
15567 From Nicolas Joly.
15569 2001-08-03 Akim Demaille <akim@epita.fr>
15571 Clean up the handling of the M4 builtins tracing exception.
15573 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15574 trace requests.

15578 (&parse_args): Complete the trace requests with alternate names.
15579 (&handle_traces): Hence no longer do it here.
15580 (&trace_requests): Remove, unused.
15582 2001-08-03 Akim Demaille <akim@epita.fr>
15584 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15585 m4_if, and m4_wrap.
15587 2001-08-03 Akim Demaille <akim@epita.fr>
15589 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15590 (m4_divert_pop): Dump the whole diversion stack when a diversion
15591 mismatch happens.
15592 * bin/autom4te.in (&handle_output): Remember of the first
15593 occurrence of a possibly undefined macro, not the last.
15594 Complain about the possibly undefined macros in the same order as
15595 the appear in the output.
15596 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15597 * tests/tools.at (autoconf: forbidden tokens, basic)
15598 (autoconf: forbidden tokens, exceptions): No longer sort
15599 autoconf's stderr, as it is now deterministic.
15600 Check that `dnl' is caught.
15602 2001-08-01 Akim Demaille <akim@epita.fr>
15604 * configure.ac: Bump to 2.52c.

15618 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
15619 `die'.
15620 (&END): New.
15621 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
15622 `END', as `Autom4te::General::END' will be triggered.
15623 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15624 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

16016 compiler, not the preprocessor.
16017 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

16023 2001-07-03 Akim Demaille <akim@epita.fr>

16053 dummy alternate main is required even if the user provides her own
16054 'main'.

16056 provide an alternate 'main' function name, using the 'main' from
16057 the Fortran libraries.
16058 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
16059 cross-language link tests can be performed successfully.
16060 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
16061 after $LIBS, for consistency; this should be the general rule since

16065 2001-06-29 Pavel Roskin <proski@gnu.org>
16067 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
16068 at-stdout and at-stderr instead of removing the newline
16069 from the echo output, which is not guaranteed to work.
16071 2001-06-28 Jens Petersen <petersen@redhat.com>
16073 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
