1217 Cover more potentially problemtic file names. Use the new
1220 Properly handle funny file names for headers in config.status.
1221 The test suite did not cover this bug because the code was not
1222 quoting properly the arguments of `rm -f' (which "fails" silently)
1223 as well as the arguments of `diff' (whose output was redirected to
1224 /dev/null so we couldn't see its error message).

1342 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1344 <DEFAULTS>: Delay computation of variables based on $at_dir...
1345 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1346 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1347 <PARSE_ARGS>: Parse new option.
1348 <HELP_TUNING>: Document it.

1364 * doc/autoconf.texi (Particular Programs): Do not mention the
1365 Autoconf version in which the AC_PROG_INSTALL change was done.
1366 Suggested by Paul Eggert.
1368 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1370 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1371 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1372 mode, we change to the source directory, also set $ac_pwd so we
1373 do not go back to the build tree for the next config subdir.
1374 * tests/torture.at (Deep Package): Extend test to contain two
1375 config subdirs on the top level.
1377 Fix parallel `maintainer-check'.
1378 * Makefile.am (maintainer-check-tests): Depend on `all'.
1379 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

1406 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1408 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1409 check_SCRIPTS. Building the wrappers for `all' allows help2man
1410 to use them for the manpages.
1411 Report by Benoit Sigoure.
1413 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1415 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1417 Fix some write failure cases in Autotest.

1429 (m4_require): Use m4_do, not m4_join.
1431 Fix some whitespace tests on cygwin.

1436 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1438 Optimize AC_REQUIRE.

1441 (m4_require): Avoid extra macro calls.

1445 * tests/torture.at (srcdir): Fix quoting.

1448 * tests/autotest.at (srcdir propagation): Copy install-sh to

1451 * tests/base.at (Input/Output): Likewise.
1452 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1453 config.guess, and config.sub to test source tree.
1454 Drop AC_CONFIG_AUX_DIR setting.
1455 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1456 * tests/torture.at (Substitute a 2000-byte string): Drop
1457 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1458 (Substitute a newline, datarootdir workaround): Likewise.
1459 (Define a newline): Adjust for linenumber changes in configure.ac.
1460 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1467 * tests/tools.at (Syntax of the shell scripts): Likewise.
1469 * tests/m4sh.at (LINENO): Quote $0.
1471 Fix testsuite program wrapper for whitespace in `pwd`.
1472 The problem here is that the usual mantra is that command
1473 variables can contain arguments, thus we cannot just escape
1474 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1475 $top_builddir/tests directory early in $PATH, so that the
1476 wrappers are found by their plain name.
1477 * tests/wrapper.as: Put $testdir early in $PATH.
1478 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

1490 <at_func_create_debugging_script, Driver Loop>:
1491 Quote $at_group_dir.
1492 * tests/autotest.at (whitespace in absolute testdir): New test.
1494 * lib/autom4te.in: Quote @datadir@.
1496 Proper file name escaping in Autoconf programs and Perl modules.
1497 This includes escaping of characters special to the shell
1498 as well as special to Perl, e.g., leading `<' or `>'.
1499 For example, when $file starts with `>', `open ">$file"'
1500 wrongly tries to append to a different file.
1501 * bin/autoconf.as: Fix quoting for autom4te options.
1502 * lib/Autom4te/General.pm (shell_quote): New function, taken
1503 from coreutils, written by Jim Meyering.
1505 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1507 * bin/autoreconf.in (parse_args): Likewise.
1508 * bin/autoscan.in (main): Likewise.

1511 * bin/ifnames.in: Likewise, XFile usage fixes.
1512 * tests/tools.at (autom4te and whitespace in file names): Extend
1513 test. Test twice, with special characters allowed on w32, and the
1514 rest. Test leading and trailing whitespace, for `open_quote'.
1515 (autotools and whitespace in file names): New, analogous test.
1516 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1517 by Russ Allbery and Eric Blake.
1520 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1521 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1522 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1523 (update_file, contents): Use it.
1525 * Makefile.am (autom4te-update): Rewrite for git.

1529 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1531 Fix copyright years.
1532 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1533 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1535 2007-12-04 Eric Blake <ebb9@byu.net>
1537 Manually resync with gnulib, since 'make cvs-update' no longer works.
1538 * build-aux/config.guess: New upstream version.
1539 * build-aux/config.sub: Likewise.
1541 When using older automake, don't downgrade build-aux/texinfo.tex.
1542 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1543 * doc/Makefile.am (TEXINFO_TEX): Add.
1545 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1547 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1548 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1549 #undef as this runs afoul of our new way of creating config.h.
1550 Problem reported by Jim Meyering in
1551 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1553 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1555 Fix autom4te for unusual characters in input file names.
1556 * bin/autom4te.in (files_to_options): Quote active characters
1558 * tests/tools.at (autom4te and white space in file names):
1561 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1562 Document that Tru64 awk always splits $0.
1564 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1566 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1567 `#AT_STOP_...' line at the end of each test.
1569 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1571 * lib/autotest/general.m4 (AT_INIT): For awk line number
1572 extraction script, ensure `$at_group' has a defined value
1573 even for the empty set, and properly quote its usage inside
1576 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1578 * doc/autoconf.texi (Shell Functions): New chapter. Document
1579 IRIX sh $0 issue in functions, move content from ...
1580 (Portable Shell): ... here.
1581 (Shell Script Compiler): Note that shell functions are not
1582 totally unportable any more.
1584 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1585 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1587 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1588 extracting the line numbers of the last needed test.
1590 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1592 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1595 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1597 Fix IRIX testsuite debugging failures: $0 in functions.
1598 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1599 Do not use $0 inside a function, as IRIX sh will set that to the
1600 function name rather than the script invocation name.
1602 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1603 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1605 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1606 to extract test scripts.
1607 (AT_INIT): Extract and cache test script line numbers.
1609 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1611 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1612 subsequent fixups; the awk -> here-document conversion trashes
1613 performance too much with AIX sh.
1615 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1617 * tests/local.at: Do not test m4, perl with AT_TESTED.
1619 Diagnose and guard against write errors dealing with config.status.
1620 The general idea is this: all write failures from `configure'
1621 writing `config.status' are indicated by $ac_write_error, which
1622 is only checked at the end. This is safe because config.status
1623 code is not executed before the file is complete. Other write
1624 failures, be they inside config.status, or in sub shell/awk
1625 scripts spawned from configure or config.status, typically need
1626 earlier checking, as their results are used right afterwards.
1627 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1628 before writing config.status, check afterwards.
1629 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1630 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1631 Set `ac_write_error' for write failures to config.status. Barf
1632 upon write failures to temporary files.
1633 Adjust note about closing and reopening the here-document.
1634 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1635 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1636 reopening the here-document.
1637 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1638 Ensure `ac_write_error' does not escape into config.status.
1639 Also, add a couple of code paths not yet exercised in the test
1640 suite: a config file with input from stdin, and a config header
1642 Suggestion for catching write errors by Bruno Haible.
1644 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1646 Avoid error with Tru64 awk and testsuite lines with many words.
1647 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1648 reads the testsuite, set the field separator to an unusual value,
1649 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1650 even splits the input if $i, i>0, was never accessed in the script.
1652 Revert 2007-10-17 change.
1653 * TODO: Multiline args in config files and headers mean something
1654 different and are not fixed, see
1655 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1656 Report by Stepan Kasal.
1658 * doc/autoconf.texi (Generic Programs): Fix typo.
1660 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1662 AC_*_TOOL does not canonicalize the prefix
1663 * doc/autoconf.texi (Generic Programs): Do not say that
1664 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1666 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1668 Diagnose write errors in config.status instantiations.
1669 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1670 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1672 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1673 Extend test to also check for some write error failures, using...
1674 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1675 Report by Bruno Haible.
1678 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1680 (_AT_CHECK): Use less indentation, to save space.
1682 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1684 Add witness macro for @top_build_prefix@ substitution.
1685 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1686 (_AC_OUTPUT_FILE): Mention it here.
1688 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1689 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1691 * lib/autotest/general.m4 (at_func_test): Remove.
1692 (AT_INIT): Pre-extract test groups into separate files.
1693 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1694 Remove at-test-source files together with the $at_group_dir.
1695 * tests/autotest.at (Long test source lines): New test.
1697 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1699 Shell functions and variables may share a namespace.
1700 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1703 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1705 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1708 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1710 * lib/autoconf/status.m4: Fix a couple of comment typos.
1712 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1714 2007-11-13 Jim Meyering <meyering@redhat.com>
1716 Clean up the rule to create "expr".
1717 * tests/Makefile.am (expr): Don't redirect directly to target.
1718 Redirect just once, not for each echo statement.
1719 Use $@, not literal "expr".
1721 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1723 Don't worry about preprocessor when testing long long.
1724 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1725 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1726 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1727 These no longer check for preprocessor flaws.
1728 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1729 Do not check for preprocessor flaws.
1731 2007-11-13 Jim Meyering <meyering@redhat.com>
1733 Adapt dependencies, now that a version change doesn't modify configure.ac
1734 * GNUmakefile: Remove "make clean" kludge.
1735 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1737 Don't redirect directly to target.
1738 Use $@, not literal "version.m4".
1740 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1742 * doc/autoconf.texi (Making testsuite Scripts): Document
1743 ":;{" shorthand as in previous patch.
1745 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1747 * doc/autoconf.texi (Limitations of Builtins): Document problem
1748 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1750 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1751 Use ":;{" shorthand.
1752 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1754 2007-11-12 Jim Meyering <meyering@redhat.com>
1756 Add more non-srcdir build support.
1757 * GNUmakefile (dummy): Split a long line.
1758 Add -v option to autoreconf invocation.
1760 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1761 * GNUmakefile (dummy): Remove INSTALL.
1763 Remove racy commands to build scripts in bin/ and tests/.
1764 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1765 are guaranteed to be built, remove the rules that tried to build
1766 them. Before, with a parallel build, these rules could lead to
1767 two processes writing tests/wrapper.in concurrently.
1769 Build in man/ only *after* building in bin/ and tests/.
1770 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1771 in both bin/ and tests/.
1773 Accommodate non-srcdir build-from-checkout.
1774 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1775 Use git's --git-dir=$srcdir/.git option.
1776 Add quotes, in case tarball_version_file contains shell meta-characters.
1777 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1778 * configure.ac: Pass "." to git-version-gen.
1780 Avoid spurious test failures due to version skew.
1781 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1783 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1785 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1786 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1787 Remove conftest.dSYM directory.
1788 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1789 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1790 Remove `conftest.*' recursively.
1791 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1792 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1794 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1796 Report and analysis by Jeff Squyres and Peter O'Gorman.
1798 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1800 Fix typos in variable names.
1801 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1803 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1805 Document that $((expression)) is not portable.
1806 * doc/autoconf.texi (Shell Substitutions): Here.
1808 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1810 Ignore configure --help* errors due to LINENO-impaired shells.
1811 * tests/torture.at (Configuring subdirectories, Deep Package):
1812 In the --help* tests in read-only trees, make `.' temporarily
1813 writable again for the `stderr' file, and ignore errors due to
1814 the attempt to write configure.lineno.
1815 Report by Patrick Welche.
1817 2007-11-10 Jim Meyering <meyering@redhat.com>
1819 Generate package.m4 in build-dir, not srcdir.
1820 * tests/Makefile.am (package.m4): Adjust target.
1821 Don't redirect directly to $@.
1822 (CLEANFILES): Add package.m4.
1823 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1825 When running $(AUTOTEST), search "." before searching $(srcdir).
1827 Avoid a race condition that would make parallel "distclean" fail.
1828 * tests/Makefile.am (distclean-generic): Replace the default,
1829 automake-provided rule with an identical one, but with an additional
1830 dependency on distclean-local. Simply adding the dependency would
1831 cause automake not to emit the rule at all.
1832 * BUGS: Building with -jN works, now.
1834 Distribute git-version-gen.
1835 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1836 since GNUmakefile is distributed, and requires it for dist* rules.
1838 Remove two more generated files from version control.
1839 * INSTALL: Remove generated file.
1840 * lib/autoscan/autoscan.list: Remove generated file.
1842 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1844 * GNUmakefile (PATH): Remove stray apostrophes; they become
1845 part of PATH, which isn't wanted here.
1847 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1849 New config files output variable `top_build_prefix'.
1850 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1852 * doc/autoconf.texi (Preset Output Variables): Document it.
1854 Report by Bob Friesenhahn.
1856 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1857 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1858 function, to parametrize arithmetic with expr vs. the shell.
1859 Use it where possible.
1860 Suggestion by Benoit Sigoure.
1862 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1864 Adjust the documentation of autotest WRT atlocal.
1865 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1866 when using Automake, to write a rule to produce atlocal, since it's
1867 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1868 distributed, not atconfig.in.
1870 2007-11-04 Eric Blake <ebb9@byu.net>
1872 Update list information.
1873 * README: Mention new autoconf-commit list.
1874 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1876 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1878 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1880 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1882 * build-aux/.gitignore: Ignore mkinstalldirs.
1884 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1886 2007-11-03 Jim Meyering <meyering@redhat.com>
1888 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1889 * build-aux/git-version-gen: This syncs from coreutils.
1891 Adjust the build procedure so "make check" works reliably.
1892 * README-hacking: Include an extra step between "make" and
1893 "make check" to ensure that the latter passes.
1895 Use just-built tools, when possible.
1896 * GNUmakefile (PATH): Set and export here, ...
1897 (dummy): ... rather than here.
1899 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1900 and Andreas Schwab <schwab@suse.de>
1902 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1905 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1907 * configure.ac (AC_PREREQ): Require version 2.60, for
1908 AC_PROG_SED, AC_PROG_GREP.
1910 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1911 and Jim Meyering <meyering@redhat.com>

1920 2007-11-03 Eric Blake <ebb9@byu.net>
1922 Support m4 1.4.5 in testsuite.
1923 * tests/torture.at (Define a newline): Exclude line numbers in
1925 Reported by Ralf Wildenhues.
1927 2007-11-03 Jim Meyering <meyering@redhat.com>
1929 Remove automake-provided files from version control.
1930 * build-aux/elisp-comp: Remove file.
1931 * build-aux/install-sh: Remove file.
1932 * build-aux/missing: Remove file.
1933 * build-aux/mdate-sh: Remove file.
1934 * build-aux/.gitignore: New file.
1935 Suggestion from Ralf Wildenhues.
1937 2007-11-03 Eric Blake <ebb9@byu.net>
1939 Adjust version comparison to account for git snapshot numbers.
1940 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1941 component separator.

1943 <m4_version_compare>: Document this change.
1944 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1946 2007-10-30 Bruno Haible <bruno@clisp.org>
1948 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1949 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1950 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1951 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1952 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1953 Suggested by Paul Eggert.
1955 2007-10-28 Jim Meyering <meyering@redhat.com>
1957 * README-hacking: Autoconf, Automake, and Perl are required to build.
1958 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1960 2007-10-28 Jim Meyering <meyering@redhat.com>
1962 README-hacking: Recommend running autoreconf -vi.
1963 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1964 so that we use just-built tools when they're available.
1965 Suggestions from Ralf Wildenhues.
1967 2007-10-28 Jim Meyering <meyering@redhat.com>
1969 Make inter-release --version output more useful.
1971 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1972 which indicates that it is built using the 19th change set
1973 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1974 is a prefix of the commit SHA1.
1975 * build-aux/git-version-gen: New file.
1976 * configure.ac: Run it to set the version.
1977 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1978 * Makefile.am (dist-hook): Arrange so that .version appears only
1979 in distribution tarballs, never in a checked-out repository.
1980 * .gitignore: Add .version here, too. Just in case.
1981 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1982 not configure.ac, now that the version number changes automatically.
1984 Ensure that $(VERSION) is up to date for dist-related targets.
1985 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1986 git-version-gen doesn't match $(VERSION), but only for dist targets.
1988 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1996 Remove all generated files from version control.
1997 * aclocal.m4: Remove.
1998 * configure: Remove.
1999 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2000 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.

2005 Improve corner case of m4_expand.
2006 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

3262 for C++; this drops support for anonymous struct and union types,
3263 which were problematic anyway.

3283 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3284 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3285 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3286 works but the latter doesn't, then it's a valid type.
3287 This lets people use function types and so forth.
3288 For C++ there doesn't seem to be a simple solution, so leave it alone.
3289 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3290 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3291 AC_CHECK_TYPE; that wasn't documented or necessary.

3500 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3502 * doc/autoconf.texi: Fix some typos.
3504 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3506 Fix some wording problems noted by Paolo Bonzini in:
3507 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3508 * doc/autoconf.texi (Signed Overflow Examples): Give more
3509 discussion about the allow_superuser_privileges example,
3510 and change it a bit to make things clearer.
3511 (Optimization and Wraparound): Clarify whether the compiler
3512 will generate an infinite loop for the example derived from
3513 Autoconf's mktime test.
3514 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3515 Also, clarify unsigned multiplication overflow.
3517 2007-01-04 Eric Blake <ebb9@byu.net>
3519 * bin/Makefile.am (RELEASE_YEAR): New macro.
3520 (edit): Use it to supply correct copyright year to scripts.
3521 * bin/autoconf.as (version): Use it.
3522 * bin/autoheader.in ($version): Likewise.
3523 * bin/autom4te.in ($version): Likewise.
3524 * bin/autoreconf.in ($version): Likewise.
3525 * bin/autoscan.in ($version): Likewise.
3526 * bin/autoupdate.in ($version): Likewise.
3527 * bin/ifnames.in ($version): Likewise.
3529 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3531 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3532 feedback. The most important changes document what happens when
3533 you convert an out-of-range value to a signed integer type, and
3534 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3537 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3538 rewrite, taking notions from the recent discussion on the gcc and
3539 autoconf mailing lists; please see
3540 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3541 and follow the many links.
3542 (Integer Overflow Basics, Signed Overflow Examples):
3543 (Optimization and Wraparound, Signed Overflow Advice):
3544 (Signed Integer Division): New sections.
3546 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3548 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3549 preprocessor macro arguments in traced name.
3550 * doc/autoconf.texi (Defining symbols): Document longstanding
3551 support for AC_DEFINE-ing macros with arguments, and document
3552 behavior when the same variable has multiple AC_DEFINEs.
3553 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3554 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3555 macros directly, giving much shorter and simpler code.
3557 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3559 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3560 space before "$ac_configure_args" to prevent a 'config.status
3561 --recheck' failure if ac_configure_args doesn't contain a leading
3562 space. This works around a problem with the XEmacs configure.ac,
3563 which uses the (undocumented) ac_configure_args variable
3564 inconsistently with Autoconf.
3566 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3568 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3569 Include <limits.h>, and use its INT_MAX to rewrite the
3570 j loop so that it does not overflow 'int'. Problem reported by
3572 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3573 Play it safe by shifting left by 1 rather than multiplying by 2,
3574 as GCC is less likely to optimize this away when the value
3575 is signed (when it assumes overflow leads to undefined behavior).
3576 Also, don't assume time_t uses two's complement.
3578 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3580 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3581 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3582 dumps core on it. Report by Tim Rice.
3584 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3586 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3587 --disable-option-checking to --help output even when
3588 AC_PRESERVE_HELP_ORDER is not used.
3589 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3590 --with argument, rather than argument with [-.] replaced by
3592 * NEWS: Fix typo in previous change; the news was in the
3595 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3597 * NEWS: Warnings are now generated by default for unknown
3598 --enable-* and --with-* options.
3599 * doc/autoconf.texi (Option Checking): Renamed from
3600 (Configure Option Checking). Tighten up the wording a bit.
3601 (External Software, Package Options): Cross-reference to Option
3602 Checking, and use this to shorten our section.
3603 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3604 "$x" to test "x$foo" != x.
3605 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3606 Don't warn if $enable_option_checking is "no".
3607 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3608 ac_unrecognized_opts to the empty string.
3609 Don't echo the unrecognized opts, as this might mishandle
3610 backslashes or leading -.
3611 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3612 usage next to the other --disable-FEATURE options in the
3615 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3617 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3618 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3619 Print warning for unrecognized --with and --enable options
3620 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3621 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3622 Disable option checking when subdirs are configured.
3623 (AC_OUTPUT): If warnings are enabled, print warning about
3624 unrecognized --with and --enable options at the end of
3625 the configure output (as well as at the beginning).
3626 * doc/autoconf.texi (Option Checking): New node.
3627 Document new option warning functionality.
3629 2006-12-16 Eric Blake <ebb9@byu.net>
3631 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3632 * NEWS: Start news for current version.
3634 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3636 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3637 Define HAVE_GETMNTENT to 1, not to the empty string.
3638 Problem originally reported by Jochen Friedrich in
3639 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3641 This change prompted by a problem report by Andrey Simonenko in
3642 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3643 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3644 object-like macros only, in the traditional portable character
3646 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3647 Warn about attempts to define things that are not identifiers.
3648 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3649 awful hack that AC_DEFINEd macro names containing parentheses.
3651 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3653 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3654 too drastic, even if Texinfo in theory requires it for info mode.
3656 (config.status Invocation): Renamed back from Recreating a
3658 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3659 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3661 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3663 * NEWS: Version 2.61a.
3665 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3666 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3668 * NEWS: Document changes with echo and printf, and the lack
3669 of limits on the total size of multi-line values of substituted
3670 variables, and the AC_FUNC_FSEEKO fix.
3672 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3674 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3675 Writing configure.ac.
3676 (Autoconf Input Layout): Renamed from configure.ac Layout.
3677 (Recreating a Configuration): Renamed from config.status Invocation.
3678 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3679 (acconfig Header): Renamed from acconfig.h.
3680 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3681 (Writing Testsuites): Renamed from Writing testsuite.at.
3682 (Autom4te Cache): Renamed from autom4te.cache.
3684 * BUGS: Remove mention of VPATH problem, since it's now documented
3685 not to be a bug in the Autoconf build procedure itself, but rather
3686 a problem with the proprietary `make' programs.
3688 * doc/autoconf.texi (Build Directories): Add a cross reference
3691 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3692 * doc/standards.texi: Sync from gnulib.
3694 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3695 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3696 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3697 generated automatically.
3699 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3701 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3702 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3703 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3705 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3707 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3708 `CEOF$ac_eof' special marker, the awk script cannot contain a
3709 line matching `^CEOF', so this is not needed any more.
3710 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3711 special marker in the test.
3713 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3715 * tests/tools.at (autom4te preselections): Use `find -newer';
3716 remove one of the sleeps.
3718 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3719 more readable, using ...
3720 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3722 * doc/autoconf.texi (autoheader Invocation): Do not double-
3723 quote the parameter of `AH_BOTTOM' in the example.
3725 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3727 * doc/autoconf.texi (Configuration Headers): Remove the
3728 example with multiple input files.
3729 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3730 multiple input files.
3732 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3734 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3735 creating the awk substitution script, handle one input line at a
3736 time, so that the maximum length of a substituted (multi-line)
3737 value is not limited by the size of the sed pattern space.
3738 The trade-off is a slightly repetitive sed script.
3739 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3740 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3741 * tests/torture.at (Substitute a 2000-byte string): Increase the
3742 test with several long lines, they should not be caught by sed
3745 * tests/tools.at (autom4te preselections): New test, to flag
3746 entries missing from autom4te.cfg.
3747 Report by David Byron <dbyron@hheld.com>.
3749 * tests/torture.at (Substitute a 2000-byte string): Actually use
3750 AC_PROG_AWK, so the last change works as intended.
3751 (Substitute and define special characters): Likewise.
3752 (Substitute a newline): Likewise.
3754 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3755 instead of `awk' consistently.
3756 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3757 * tests/torture.at (Torturing config.status): Test both the
3758 result of AC_PROG_AWK and plain awk.
3759 (Substitute a 2000-byte string): Likewise.
3760 (Substitute and define special characters): Likewise.
3761 (Substitute a newline): Likewise.
3763 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3765 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3766 can be assigned to a function pointer. Problem reported by
3767 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3768 part of a patch by Ralf Wildenhues in that same bug report.
3770 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3772 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3773 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3775 2006-12-01 Eric Blake <ebb9@byu.net>
3777 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3778 cross-compiling from cygwin to mingw.
3779 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3780 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3781 to lib/autoconf/c.m4.
3783 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3785 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3786 string for more reliable failure. Wrap the entire test that
3787 causes the broken Solaris printf to dump core, in a subshell,
3788 so the segmentation fault message is reliably suppressed.
3789 Fix shell expansion errors by using /usr/ucb/echo always;
3790 avoid an error on systems without it by another subshell.
3791 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3792 subshell-$as_echo to `as_echo', for better error message.
3794 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3796 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3797 `BASH_SOURCE' contain a newline, set them to empty, as they may
3800 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3802 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3803 years and is too hard to maintain now. The last straw was
3804 reported by Jerker Baeck in
3805 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3806 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3807 * doc/autoconf.texi (Particular Functions): Move
3808 AC_FUNC_SETVBUF_REVERSED from here...
3809 (Obsolete Macros): ... to here. Say that it does nothing now.
3810 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3811 Turn into (almost) a no-op.
3813 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3815 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3816 These macros are obsolescent and new applications shouldn't need them.
3817 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3818 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3819 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3820 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3821 (AC_FUNC_VPRINTF): Likewise.
3822 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3823 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3824 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3826 * doc/autoconf.texi (Setting Output Variables): Mention that
3827 @VAR1@VAR2 has unspecified behavior. Problem reported by
3829 * NEWS: Mention this.
3831 * Makefile.am: Put only a single '#' into the copyright notice,
3832 so that it's also present in the output file. Standardize wording
3833 in makefile copyright notices to match GNU coding standards.
3834 * bin/Makefile.am: Likewise.

3847 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3849 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3850 in the sed script that mangles the awk script: delete up to the
3851 first exclamation mark only.
3852 * tests/torture.at (Substitute and define special characters):
3855 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3857 Rewrite config files generation: avoid quadratic growth in
3858 the number of substituted variables by using awk instead of sed
3859 for the bulk of the substitutions.
3860 * NEWS: Mention this.
3861 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3862 forbidden in the output (and thus input) file.
3863 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3864 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3865 generate just one large awk script for substitutions,
3866 eliminating much of the earlier complexity, while adding some
3867 new complexity. Only expand the substitution templates at
3868 configure time, for smaller configure script size. If
3869 _AC_SUBST_FILES are used, test 'awk' for working getline support
3870 at config.status time. If absent, interpolate through the
3871 shell. The awk script was written with much help
3872 from Paolo Bonzini and Paul Eggert.
3873 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3874 (_AC_SED_FRAG_NUM): Likewise.
3875 (_AC_SUBST_CMDS): Renamed from...
3876 (_AC_SED_CMDS): ...this.
3877 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3878 * tests/torture.at (Substitute a 2000-byte string): Also
3879 substitute a line with 1000 words, and a variable with several
3881 (Substitute and define special characters): Test awk special
3882 characters, and put substitution input strings `@foo@' in the
3883 output, to test that no recursion happens; test several other
3884 combinations from Paolo Bonzini.
3886 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3888 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3889 that replaced echo with AS_ECHO where this wasn't necessary.
3890 Problem reportd by Ralf Wildenhues.
3891 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3892 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3893 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3895 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3897 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3899 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3901 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3902 that traditional Awk lacks 3-arg "split". It has it.
3903 Mention that FS must be a single character, and a few other
3904 99-byte limits of traditional Awk.
3905 Mention that if (i in a) doesn't work with traditional Awk.
3907 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3909 * tests/autotest.at (BSx641-newline in command):
3910 (BS-BS-newline in command, BSx640-newline in command):
3911 (Newline-CODE-BS-newline in command):
3912 (Single-quote-BS-newline in command):
3913 (Single-quote-newline-BS-newline in command):
3914 Use printf '%s\n' instead of echo, for portability to hosts
3915 where echo interprets backslashes. This will break on hosts
3916 that lack printf, but for now let's assume all such hosts
3917 are dead (if not, we should get reports of test failures).
3919 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3921 'echo' has some portability problems, when given a first argument
3922 with a leading '-', or when given any argument containing '\'.
3923 Avoid using 'echo' in these cases.

3944 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
3945 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
3946 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
3947 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3948 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3949 * bin/autoconf.as: Redo verbose flag implementation, as the old
3950 scheme wouldn't work with AS_ECHO.
3951 * lib/autotest/general.m4 (AT_INIT): Likewise.
3952 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3953 Don't use ECHO_T, since ECHO_N is now reliable.
3954 * lib/autotest/general.m4 (AT_INIT): Likewise.
3955 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3956 rather than using a here-document to put the script into a file.

3960 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3961 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3962 bug, but we might as well stop using ECHO_N and ECHO_C internally.

3965 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

3967 operand, as AS_ECHO requires. Avoid double file name expansion.
3968 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3969 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3970 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3971 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

3973 Double-quote strings that would otherwise contain M4 comments.
3974 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3976 * configure.ac (AC_INIT): Bump to 2.61a.
3979 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3983 * configure.ac (AC_INIT): Bump to 2.61.
3986 * tests/autotest.at (Macro with backslash in a test title):
3987 Comment out for now, as this tests neither fails nor passes
3988 reliably. Problem reported by Ralf Wildenhues.
3990 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3992 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

4071 and Joel E. Denny <jdenny@ces.clemson.edu>
4072 and Paul Eggert <eggert@cs.ucla.edu>
4074 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4075 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4078 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4080 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4081 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4082 Imported from a similar patch to gnulib by Bruno Haible.
4084 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4086 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4103 and Stepan Kasal <kasal@ucw.cz>
4105 Handle special characters in test case titles correctly.

4108 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4109 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4110 argument. Extend to check titles printed by ./micro-suite and

4113 Single-quote in a test title,
4114 Double-quote in a test title): Don't expect failure anymore.
4115 (Backslash in a test title): Put a non-whitespace character after the
4116 backslash so that Bourne shells might actually see it as an escape
4118 (Brackets in a test title,
4119 Pound in a test title,
4120 Comma in a test title,
4121 Quoted Macro in a test title,
4122 Macro in a test title,

4124 (Macro with backquote in a test title,
4125 Macro with double-quote in a test title,
4126 Macro with backslash in a test title): New tests expected to fail.
4127 * tests/torture.at (#define header templates): M4-quote this title in
4128 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4129 The visible effect was a stray [] in the testsuite output.
4131 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4133 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4134 `trap ... 0' inside a function, for AIX sh.
4136 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4138 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4139 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4140 5363) simply issues a warning when dividing by zero at compile
4141 time. Problem reported by Elias Pipping.
4143 2006-10-26 Eric Blake <ebb9@byu.net>
4146 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4147 show effect on macros that expand with commas.

4170 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
4172 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4174 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4175 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4176 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4177 reported by Nelson H. F. Beebe for Coreutils 6.4.
4179 * tests/tools.at (autoconf --trace: user macros): Remove test
4180 for tracing multiline macros, since m4 1.4.7a uses a different
4181 way to number lines. Problem reported by Ralf Wildenhues.
4183 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4185 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4186 /dev/null since the heuristics for interactive behaviour was

4190 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

4207 * NEWS: Remove AC_CACHE_CHECK_INT.
4208 * doc/autoconf.texi (Caching Results): Likewise.
4209 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4210 AC_CACHE_CHECK_INT, since it's no longer public.
4211 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4212 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4240 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4242 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4243 looking for special shell characters.
4244 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4245 macro defined by AS_VAR_PUSHDEF before passing it as a

4257 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4259 (Imported from Automake.)
4260 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4261 which incorrectly sets the mode of an existing destination
4262 directory. In some cases the unpatched install-sh could do the
4263 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4264 system. We hope this is rare in practice, but it's clearly worth
4265 fixing. Problem reported by Alex Unleashed in
4266 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4267 Also, don't bother to check for -m bugs unless we're using -m;
4268 suggested by Stepan Kasal.
4270 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4272 Import this change from Automake:
4274 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4275 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4276 is enabled by default with gnu and gnits strictness.
4277 Report from Bruno Haible.
4279 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4280 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4281 gnu and gnits modes.
4283 Import this change from Config:
4285 2006-09-20 Ben Elliston <bje@gnu.org>

4288 Import this change from Gnulib:
4290 2006-09-16 Karl Berry <karl@gnu.org>
4291 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4292 to avoid sectioning errors.
4294 Import these changes from Texinfo:
4296 2006-10-04 Karl Berry <karl@gnu.org>
4297 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4298 (\quoteexpand): rename to \rquoteexpand.
4299 (\codequoteleft): new def, to look for @set codequotebacktick.
4300 (\lquoteexpand, \quoteexpand): new defs.
4301 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4302 (\code): must use new \...Char values, since now ` is active.
4304 2006-08-26 Karl Berry <karl@gnu.org>
4305 * build-aux/texinfo.tex (\textdegree): New command.
4307 2006-08-12 Karl Berry <karl@gnu.org>

4312 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4314 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4316 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4317 added to the template can get mangled.
4319 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4321 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4322 include the default headers, and redefine obstack_chunk_alloc
4323 and obstack_chunk_free. Fixes false failure with glibc.
4325 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4327 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4328 for backward compatibility with Libtool 1.5.22. Problem reported
4331 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4333 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require

4337 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4339 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4340 the NonStop platform.
4341 * doc/autoconf.texi (Posix Variants): Likewise.
4342 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4344 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4345 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4346 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4347 Use a better substitute, by inspecting the output of "ls"
4348 rather than just using ":".
4349 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4350 rather than AS_EXECUTABLE_P, since we needn't worry about
4351 non-regular files here.
4353 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4354 due to configuration hassles with this. See Tonya Underwood's report
4355 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4356 * doc/autoconf.texi (Special Shell Variables): Likewise.
4358 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4359 Stepan Kasal <kasal@ucw.cz>
4361 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4362 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4364 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4366 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4367 initialization which is not inherited through the environment
4368 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4369 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4371 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4373 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4374 problems with mkdir -p -m.
4376 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4378 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4379 comment about ac_cpp_err; it was incorrect, and anyway
4380 ac_cpp_err is being removed below.
4381 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4382 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4383 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4385 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4386 with werror_flag and conftest.err and so forth. This is more
4387 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4388 and anyway the user shouldn't normally want to see this gorp logged.
4389 Problem reported by Ralf Wildenhues.
4390 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4391 empty, not 'no', since the rest of the code uses 'test -z'.
4393 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4395 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4396 Use a single call to AC_DO_TOKENS rather than multiple, for
4398 (_AC_LINK_IFELSE): Test that resulting file is executable.
4399 Problem reported by mwoehlke in
4400 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4402 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4403 than creating a file to use with test -x; this is much faster.
4405 2006-10-02 Bruno Haible <bruno@clisp.org>
4407 * lib/autom4te.in (Automake-preselections): Add
4408 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4410 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4412 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4413 standard error, `experr' should be used, not `expout'.
4415 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>

4869 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4871 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4872 after -R regardless of host. Patrick Welche reports that this
4873 fixes things on NetBSD 3.99.
4875 * NEWS: Recommend M4 1.4.5.
4877 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
4878 * tests/tools.at (autom4te cache): Update wording of diagnostic
4881 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4883 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4884 under AC_C_VOLATILE.
4885 (Volatile Objects): Be a little less skeptical about what
4886 "volatile" means. Derived from thoughts by Ben Pfaff in
4887 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4889 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4891 * doc/autoconf.texi: Fix some typos.
4893 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4895 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4896 more globally, since the 2006-06-30 patch didn't suffice. Problem
4897 reported by Keith Marshall. Also, don't bother with builddir2,
4898 since it shouldn't be needed any more.
4900 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4902 * doc/autoconf.texi (Generic compiler characteristics):
4903 Document AC_COMPUTE_INT. Fix wrong statements on Default
4904 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
4906 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
4907 (_AC_COMPUTE_INT): Add obsoletion warnings.
4908 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
4911 * NEWS: Document change.
4913 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
4915 * doc/autoconf.texi (Volatile Objects): New section.
4917 * NEWS: Document previous change.
4919 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4921 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4922 Require that long long int be at least 64 bits wide. C99 requires
4923 this and enough programs depend on it so we should check for it.
4924 Bruno Haible reports in
4925 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4926 that long long int is 32 bits wide with some nonstandard compilers.
4927 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4929 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4931 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4932 to a nonexistent file, so that we don't have to worry about
4933 a local site configuration that doesn't use /usr/local.
4934 Problem reported by Keith Marshall in
4935 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4937 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4939 * doc/autoconf.texi: Be more consistent about using @acronym with
4940 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4941 quite right (it talked about "OSF/Tru64", even though the
4942 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4943 and it even mentioned "OSF 4"!) and at this point there's little
4944 reason to talk about OSF any more, since it died in 1994.
4945 (Specific Compiler Characteristics): Simplify example of
4946 negative-size array.
4947 (File Descriptors): Reorder to make the text flow better.
4948 Remove joke about "appreciate the various levels"; I didn't get it.
4949 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4950 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4951 (File Descriptors, Limitations of Usual Tools):
4952 Tone down the advice against renaming or removing open files.
4953 (Limitations of Usual Tools): Add a new section, on 'rm'.
4955 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4957 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4958 -lXt in LIBS, idea from Karsten Hopp; this was due since
4961 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4962 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4963 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4964 (which belong to Xt, not X itself). See Debian bug 327655.
4966 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4968 * configure.ac (AC_INIT): Bump to 2.60a.
4971 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4975 * configure.ac, NEWS: Update.
4977 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4979 * config/texinfo.tex: Sync from upstream.
4981 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4982 quadrigraph correctly in traces.
4984 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4987 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4988 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4990 * doc/autoconf.texi (Changed Directory Variables): New node,
4991 to document the whole `datarootdir' business a bit better.
4993 * tests/torture.at (datarootdir workaround): Extend test.
4994 Prompted by report by Alexandre Julliard.
4996 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4998 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4999 when using default mode of IBM C 6 for AIX. Problem and two-line
5000 fix reported by Larry Jones.
5002 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5004 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5005 about literal '${datarootdir}' if a definition is found in the
5008 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5010 * NEWS: Use "M4" rather than "m4" when appropriate.
5011 Problem reported by Eric Blake.
5012 * doc/autoconf.texi: Likewise.
5013 Use @acronym around BSD, GCC, and GNU when appropriate.
5014 (Why GNU M4): Renamed from "Why GNU m4".
5015 (Redefined M4 Macros): Mention that Posix
5016 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5017 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5020 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5022 * bin/autom4te.in (handle_output): Do not forbid the empty
5024 * tests/tools.at (autoconf: the empty token): New test.
5026 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5028 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5029 calls, so that we do not care whether they are LIFO or FIFO;
5030 in the m4_wrap, do not check which diversion is the topmost
5031 one, just check that the stack is balanced at the end.
5032 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5033 base diversion forever--pop the previous diversion before
5034 opening the new one; consequently, remove the m4_wrap call.
5035 * lib/autotest/general.m4 (AT_INIT): Likewise.
5036 * tests/m4sugar.at: Do not use
5037 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5039 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5040 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5042 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5043 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5044 Rework example of m4wrap token-pasting trouble so that it doesn't
5045 care whether it's LIFO or FIFO.
5046 Fix some "contrary to"s that are awkward in English.
5048 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5050 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5051 to `yes' instead of `int$1_t' if the type is found, for more
5052 consistent configure output (where $1 is the number of bits).
5053 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5054 Suggested by Bruno Haible.
5056 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5057 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5058 with system headers. Report by Bruno Haible.
5060 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5062 * config/config.guess, config/config.sub: Sync from upstream.
5064 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5065 in order to avoid picking up an older installed frozen m4sh.m4f.
5066 Besides an outdated shell startup, this could have been created
5067 by an earlier M4 version with incompatible frozen file format.
5069 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5071 * README: Recommend m4 1.4.4 instead of 1.4.3..
5072 * doc/autoconf.texi: Likewise.
5073 (Special Chars in Names): Say that $(.FOO) is portable, as
5074 suggested by Stepan Kasal.
5075 (Installation Directory Variables, Build Directories):
5076 (Automatic Remaking, Subdirectories, Fortran Compiler):
5077 (Making testsuite Scripts, Defining Directories):
5078 Quote variable usages better.
5079 (Making testsuite Scripts): Add clean-local rule to makefile
5080 snippet, by Eric Blake.
5081 (Installation Directory Variables): Fix table item font.
5082 Reword slightly to clarify. Generalize advice about
5083 not using special characters to include all file-related
5084 vars, not just VPATH.
5085 (Special Chars in Variables): Warn about special characters in
5087 (Assignments): Clarify default-value example as suggested by
5089 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5090 (Special Shell Variables): Note leading ./ or ../, as suggested
5092 (Limitations of Builtins): Under cd, warn about CDPATH.
5093 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5096 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5098 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5099 `@var', for texi2html.
5100 (Systemology): Some more word wrapping, for DVI output.
5101 (autom4te Invocation): The short option for `--melt' is `-M',
5104 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5106 * doc/autoconf.texi: More formatting and English tweaks,
5107 many suggested by Ralf Wildenhues.
5108 Reword to avoid "@code{...}'s" and the like, since it's ugly
5109 with Emacs info mode. discontents -> woes.
5110 Put a few "will"s back. time stamp -> timestamp.
5111 side-effect -> side effect.
5113 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5115 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5116 Warn about $@ not persisting. Problem reported by Julien Danjou in
5117 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5118 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5119 Mention other special chars, too.
5121 2006-06-14 Eric Blake <ebb9@byu.net>
5123 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5125 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5127 * doc/autoconf.texi: Some systematic minor improvements, as
5128 follows. Use "makefile" when talking about makefiles
5129 generally (which might be named "makefile" or "Makefile" or even
5130 "foo.mk"), "Makefile" when talking about a specific makefile
5131 called "Makefile". This unclutters the text from weird quotes
5132 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5133 values" rather than "@var{foo}s" and similar constructs containing
5134 "}s". Use "Make rules" rather than "Makefile rules". Minor
5135 English-language improvements. Change the prefix "sub-" to "sub"
5137 Put blank lines around examples more consistently.
5138 Avoid "rather" and "very" as intensifiers.
5139 Avoid "will" as an auxiliary.
5140 (Limitations of Make): Split this node into....
5141 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5142 (Leading _ in Macro Names, Backslash-Newline-Newline):
5143 (Backslash-Newline Comments, Long Lines in Makefiles):
5144 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5145 (obj/ and Make, make -k Status, VPATH and Make):
5146 (VPATH and Double-colon, $< in Explicit Rules):
5147 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5148 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5149 New nodes, resulting from splitup of Limitations of Make.
5150 All cross-references changed. Raise the top node from
5151 a section to a chapter, and all subnodes accordingly.
5152 Redo the introductory wording to match the new organization.
5153 (Installation Directory Variables): Use an example that is
5154 closer to what Autoconf actually does. Mention that VPATH's
5155 value should not contain metacharacters or white space.
5156 (Fortran Compiler): Fix a VPATH bug in an example.
5157 (Leading _ in Macro Names): Mention that this problem is no longer
5158 of practical concern.
5159 (VPATH and Make): Reword the advice to make it clearer
5160 that Autoconf and Automake support VPATH in non-GNU make, but
5161 many packages have bugs in this area.
5162 ($< in Explicit Rules): Refer to Build Directories rather
5163 than using a (non-VPATH-safe) example.
5164 (Automatic Rule Rewriting): Mention the sort of disaster that
5165 can ensue with Solaris-style rule rewriting with VPATH.
5167 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5169 * doc/install.texi (Compilers and Options): Weaken the
5170 suggestion to use GNU make for VPATH builds.
5172 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5173 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5175 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5176 in regular expression.
5178 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5180 * doc/autoconf.texi (Installation Directory Variables):
5181 Drop extra @samp from `@table @samp' item.
5182 (Limitations of Usual Tools): Comment fix.
5183 Do not nest @samp just to point to other table items.
5184 (Writing testsuite.at) <AT_CHECK>: The second argument to
5185 `@dvar' is already @samp'ed.
5186 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5187 do not use @var in the second argument.
5189 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5191 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5192 $as_shell.exe too. Problem reported by Andreas Buening in
5193 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5195 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5197 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5198 `unused variable' compiler warning, for `-Wall -Werror'.
5199 Reported by Jaap Haitsma in
5200 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5202 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5204 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5205 case the compiler dumps core. Problem reported for
5206 OpenServer 5.0.7 by Tim Rice in
5207 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5208 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5211 2006-06-06 Tim Rice <tim@multitalents.net>.
5213 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5214 "ERROR" only shows up in "make check" output if there is an
5217 2006-06-06 Eric Blake <ebb9@byu.net>
5219 * tests/tools.at (automatically allowed tokens): Fix typo.
5221 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5223 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5225 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5226 typically overflows on x86 CPUs, even though the C standard
5229 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5231 * configure.ac (AC_INIT): Bump to 2.59e.
5234 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5238 * config/texinfo.tex: Sync from upstream.
5240 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5241 seen, invoke libtoolize with `--ltdl' argument.
5242 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5244 Suggested by Eric Blake.
5246 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5248 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5249 reported by Ralf Wildenhues.

5263 message issued by AC_REQUIRE.
5264 * tests/m4sugar.at: Check m4_require's error message.
5265 * tests/base.at: Check AC_REQUIRE's error message.
5266 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5268 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5270 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5271 `expout' as the last parameter.
5272 * tests/tools.at: Adapt to the above change.
5274 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5276 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5277 information about race-free implementations of mkdir.

5286 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5288 * NEWS: GNU make now recommended for VPATH builds.
5289 Mention that some macros are now documented to be obsolescent.
5290 * doc/autoconf.texi:
5291 Prefer "current" to "modern" to describe
5292 currently-used (albeit perhaps old-fashioned) hosts.
5293 Mention which ancient features no longer need to be worried about.
5294 setgid -> set-group-ID
5295 setuid -> set-user-ID (these are the Posix terms)
5296 Fix some misuses of "only".
5297 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5298 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5299 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

5308 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5309 Mention that it's now safe to use 3 and 4.
5310 (Limitations of Usual Tools): cp -r is now specified by Posix.
5311 Omit longwinded and obsolescent discussion of cp -f.
5312 Modernize discussion of expr, ls.
5313 (Limitations of Make): Modernize discussion of VPATH builds.
5314 Mention $? as a workaround in some cases.
5315 * doc/install.texi (Basic Installation):
5316 Mention "./configure; make; make install" first. Be more
5317 specific about why this file is generic. Remove unnecessary
5318 parens. Remove misleading "only". Remove obsolete advice
5319 about csh. Don't say "configure" takes awhile; say it
5320 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5321 and CC=c99 rather than CC=c89, as these are blessed by current
5322 Posix. Recommend GNU make if doing a VPATH build.
5324 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5326 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5327 examples involving shell prompts.

5343 anywhere in directory names.
5345 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5347 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5348 about quoting the case statement, just in case.
5349 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5350 was fixed in ksh93g; reported by Ralf Wildenhues.
5352 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5354 * doc/autoconf.texi (System Services): Do not document
5355 overriding EXEEXT via ac_cv_exeext=ext.
5356 (Particular Programs) <AC_PROG_MKDIR_P>:
5357 Document that ${MKDIR_P} understands --.
5358 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5361 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5363 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5364 argument with leading hyphen. Problem reported by Paul Eggert.
5366 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5368 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5369 about quoting ac_try: quote all of it, if any of it seems suspicious.
5370 This means we don't have to worry about ${ or sed any more.
5371 Also, double-quote the case statement, to work around misuses via
5372 underquoting as reported by Ralf Wildenhues in
5373 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5374 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5375 undocumented and dangerous macro.
5376 Problem reported by Ralf Wildenhues in
5377 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5379 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5381 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5382 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5383 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5385 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5387 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5388 since evidently some packages rely on the old, broken behavior.
5389 Problem reported by Ralf Wildenhues in
5390 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5391 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5392 pre-2006-05-26 definitions, but leave in the comments that
5393 these macros are dangerous and should not be used.
5394 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5395 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5396 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5397 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5398 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5400 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5402 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5403 the use of 'tr', since this is our only use of 'tr'.
5405 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5406 and Paul Eggert <eggert@cs.ucla.edu>
5408 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5409 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5411 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5413 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5414 the output file in the `${datarootdir}' test.
5416 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5417 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5419 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5420 mention of `datarootdir' in the input file(s), but literal
5421 `${datarootdir}' in the output file, and we haven't warned yet,
5422 then warn as well: the user may have (erroneously) used
5423 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5424 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5425 * tests/torture.at (datarootdir workaround): Extend this test.
5428 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5429 and Paul Eggert <eggert@cs.ucla.edu>
5431 * doc/autoconf.texi (autoheader Invocation): The first argument to
5432 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5433 alternatives and clear up the language a bit.
5435 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5437 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5438 ac_config_guess, ac_config_sub, ac_configure.
5439 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5440 Fix typo that prevented an unnecessary space from being removed.
5441 Problems reported by Ralf Wildenhues in:
5442 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5444 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5446 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5447 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5448 Don't use the term "thread-safe" to talk about mkdir race
5449 conditions, since the problem is more a process than a thread
5450 issue. Problem reported by Stepan Kasal in:
5451 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5452 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5453 the test for 'install' more closely. Look at MKDIR_P first.
5454 Look in the PATH, and at /opt/sfw/bin.
5455 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5456 Don't bother to try mkdir -p, since we already check mkdir --version;
5457 just look at the version number. (There's no easy way to check
5458 for race-free implementations.)
5459 * tests/tools.at (autoconf: subdirectories): Adjust to above
5460 changes, since MKDIR_P now might end in "/mkdir -p".
5462 * doc/autoconf.texi (autoheader Invocation): Mention that the
5463 first arg of AC_DEFINE_UNQUOTED must be a literal.
5464 Problem reported by Ben Pfaff in
5465 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5467 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5468 * doc/autoconf.texi (Special Chars in Variables): New section.
5469 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5470 (Installation Directory Variables): Quote $(datadir) better.
5471 (Limitations of Builtins): Describe some of eval's trickiness.
5473 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5474 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5475 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5476 in front of every arg, not just trailing args. Quote apostrophes.
5477 (_AC_EVAL_ECHO): New macro.
5478 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5479 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5481 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5482 exposed by quoting of eval argument. Put the command on line line
5484 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5485 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5486 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5487 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5488 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5489 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5490 Use eval more safely.
5491 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5492 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5494 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5495 lines, exposed by quoting of eval argument.
5497 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5498 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5500 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5501 initialization of `ac_cv_exeext', do not override it if it was
5502 already set, unless it was set to `no', for compatibility with
5503 Autoconf-2.13, and comment this.
5504 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5505 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5506 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5507 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5508 Document that this test may be overridden by setting
5511 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5513 Revert these two patches:
5515 2006-04-06 Eric Blake <ebb9@byu.net>
5516 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5517 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5520 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5521 Clean up _AC_COMPILER_EXEEXT* macros.
5522 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5523 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5524 ac_file to the name of the default output file and call
5525 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5526 initial `rm' of the candidate files...
5527 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5528 the same list in subsequent `rm' calls, and for the temporary
5529 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5530 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5531 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5532 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5533 no longer needed) by libtool. Make it a cache check.
5534 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5535 copied here by mistake.
5536 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5537 _AC_COMPILER_EXEEXT.
5538 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5539 _AC_COMPILER_OBJEXT directly.
5540 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5542 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5544 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5545 Fix description of how the buggy `sed' works.
5547 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5551 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5552 ENOLCK. Only mention `make -j' when applicable. Only raise
5553 fatal errors when `make -j' is involved. Improve error message.
5555 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5557 * doc/autoconf.texi (Here-Documents): We now know more about
5558 the variable expansion in here documents bug.
5559 Thanks to Tim Rice and Stepan Kasal.
5561 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5562 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5564 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5566 * tests/autotest.at (Multiline command from M4 expansion):
5567 No failure to be expected if the shell quotes newlines in
5568 commands in the `set -x' output. Report by Tim Rice.
5571 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5573 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5574 expansion in the here-documents used by config.status, as that
5575 runs afoul of the Korn shell version M-12/28/93d bug described in
5576 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5577 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5578 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5580 2006-05-23 Jim Meyering <jim@meyering.net>
5582 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5583 Fix typo introduced with 2006-04-02 change. It reversed the sense
5586 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5588 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5589 ac_dB slightly, to save bytes in the script.
5590 Max out at 50 lines, rather than 96; this is more likely
5591 (though not guaranteed) to avoid obscure 'sed' failures.
5593 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5595 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5596 `tr -d -' as bad option argument. Work around this by deleting
5597 an unrelated character.
5598 Report by Tim Rice <tim@multitalents.net>.
5600 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5601 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5602 Stepan Kasal <kasal@ucw.cz>
5604 * doc/autoconf.texi (Particular Programs): Do not promise that
5605 we always prefer the GNU version of the program, and that we
5606 search according to PATH; both rules can have exceptions.
5607 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5608 AC_PROG_SED. Move descriptions of limitations
5609 to the Limitations of Usual Tools section.
5610 (Limitations of Usual Tools) <sed>: Mention script length
5611 limitations with Solaris /usr/ucb/sed.
5612 <grep>: Fix wording for empty alternative. Mention that -c and
5613 -l should not be combined, and that -E and -F should not be
5616 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5617 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5619 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5620 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5622 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5624 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5625 AC_DEFINE is now passed to m4_pattern_allow.
5626 * NEWS: Mention that; likewise for AC_SUBST.
5627 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5628 the parameter to m4_pattern_allow.
5629 * tests/tools.at: Add a check for that.
5631 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5633 * lib/autoconf/status.m4: Fix typos.
5635 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5637 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5638 only the files that this macro generates.
5640 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5642 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5643 the HP-UX sed limitation of 99 commands, labels do not count.
5644 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5646 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5648 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5650 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5651 Import the following fix from coreutils:
5653 2006-01-13 Jim Meyering <jim@meyering.net>
5655 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5656 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5657 not double-quote uses of that variable, to accommodate the rare
5658 case in which getmntent is available in none of the libraries
5659 checked. This happens at least on FreeBSD 5.0.
5661 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5663 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5664 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5665 some other programs unwisely rely on these undocumented vars.
5666 But put in warning comments about them.
5667 Problem reported by Ralf Wildenhues in
5668 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5669 * NEWS: Document that these variables are intended to go away.
5671 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5673 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5674 and set the language to C++ (analogous to the equivalent Fortran
5677 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5678 * doc/autoconf.texi (C++ Compiler): Document it.
5679 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5682 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5684 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5685 that caused config.status to generate 100-command sed scripts; the
5686 portable limit is 99.
5688 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5690 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5691 variable `ac_d' instead of `d' to avoid infringing namespace.
5692 Report by Ralf Menzel.
5694 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5696 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5697 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5698 * tests/tools.at (autoconf: subdirectories): New test, taken from
5699 the corresponding problem report by Ralf Wildenhues in:
5700 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5702 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5703 Quote some uses of shell variables if they might suffer unexpected
5704 globbing. This doesn't fix all instances of quoting problems that
5705 I found, just the easy ones that look safe.
5706 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5707 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5708 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5709 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5710 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5711 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5712 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5714 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5715 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5717 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5719 * bin/autoreconf.in ($help): Reword according to the manual.
5720 Suggested by Olly Betts.
5722 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5723 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5725 * bin/autoreconf.in: Pass the directory argument to
5726 `require_configure_ac'. Fix comment.
5727 * tests/torture.at (Configuring subdirectories): Expose this.
5728 Reported by Olly Betts.
5730 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5732 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5733 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5734 Automake as follows:
5736 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5737 `$configure_in' instead of `configure.in', to preserve
5738 directory component.
5740 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5742 * config/config.guess, config/config.sub, config/texinfo.tex,
5743 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5745 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5747 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5748 test for C99 conformance; (bool) 0.5 is an integer constant
5749 expression, but (bool) -0.5 is not. Problem reported by Fedor
5750 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5752 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5754 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5755 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5756 Warn about obsolete install-sh files. Remove stray sentence
5757 fragment and fix cross reference.
5758 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5759 install -d; this undoes the 2006-05-10 change.
5760 (MKDIR_P): Mark with AN_MAKEVAR.
5761 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5762 that we don't require $INSTALL to be thread-safe. Move comments
5763 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5764 of AC_PROG_INSTALL. Output a message saying that we're checking
5765 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5766 MKDIR_P instead of AC_SUBST.
5767 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5768 Special magic for MKDIR_P, too.
5769 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5771 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5773 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5775 Sync from Automake, as follows:
5777 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5778 * config/install-sh: Initialize IFS, so field splitting isn't
5780 * config/mkinstalldirs: Likewise.
5781 * config/missing: Remove superfluous quotes. Replace all uses of
5782 `[' by `test', for consistency, and for..
5783 * config/missing (sed_minuso, sed_output): New variables.
5784 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5785 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5786 Fixes `missing' to detect `--output' for help2man. Fixes
5787 PR automake/483. Report by Dennis J. Linse.
5788 (autom4te): Document in `missing --help'.
5790 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5792 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5793 * config/install-sh: Don't use 'path' to talk about file names,
5794 as per GNU coding standards. Close a race condition reported by Ralf
5795 Wildenhues and Stepan Kasal. There is still a race condition
5796 on hosts that predate Posix 1003.1-1992, but we can't help this.
5797 Don't mishandle weird characters like space on pre-Posix hosts.
5798 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5799 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5800 AC_PROG_MKDIR_P from AS_MKDIR_P.
5801 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5802 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5803 earlier editions are not (including Automake 1.8.3).
5804 Do not suggest mkinstalldirs for thread-safety.
5805 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5806 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5807 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5808 presence of special characters and race conditions.
5809 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5810 in Autoconf's name space.
5812 2006-05-10 Bruno Haible <bruno@clisp.org>
5813 and Paul Eggert <eggert@cs.ucla.edu>
5815 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5816 from Automake with minor changes.
5817 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5819 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5821 * config/install-sh: Update to Automake CVS version, as follows:
5822 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5823 * lib/install-sh: Simplify the expr implementation of dirname.
5824 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5825 * lib/install-sh: Handle --, and diagnose unknown options.
5827 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5829 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5830 `./autom4te' to create `./testsuite', since the `all' target
5831 will ensure its presence, but `installcheck' should not create
5832 the uninstalled wrappers.
5834 * tests/torture.at (Unusual Automake input files): Skip if we
5835 detect automake < 1.8.
5837 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5839 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5840 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5841 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5844 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5846 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5847 munge (multiple) white space and other oddities.
5848 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5849 single quotes in variable assignment.
5850 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5851 and similar failures by adding multiple spaces, tabs, and other
5853 Report and different test suggested by Francesco Romani
5854 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5856 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5857 single quotes, we only need to search for single quotes; this
5858 both simplifies the search pattern, and makes us less
5859 susceptible to `echo' variations for arguments not containing
5861 (_AC_ARG_VAR_VALIDATE): Likewise.
5863 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5865 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5866 `$*' and IFS concatenation issue with traditional shells and
5867 bash-2.04. Report by Seanster@Seanster.com.
5869 2006-05-03 Bruno Haible <bruno@clisp.org>
5871 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5872 precisely which Mac OS X versions have the od problem.
5874 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5876 * doc/autoconf.texi: Use @option systematically.
5878 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5879 and Bruno Haible <bruno@clisp.org>
5881 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5883 (Integer Overflow): Mention the special case of integer division
5886 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5888 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5889 traditional shells like the Solaris one that do not use the
5890 first IFS character for assembling `$*'.
5891 Prompted by a related report from autoconf_bug@nro.ca.
5893 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5894 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5896 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5897 Mention more problems with the -e option.

5902 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5904 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5905 in URLs to improve DVI formatted output (requires texinfo 4.6).
5906 (System Services, Systemology, Shellology): Likewise.
5907 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5910 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5912 (Runtime): Fix macro argument names to match description:
5913 `action-if-found' -> `action-if-true' and similarly.
5914 (Obsolete Macros): Likewise.
5915 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5916 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5917 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5919 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5921 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5924 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5927 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5929 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5930 /bin/sh set unsorted output.

5936 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5937 (Integer Overflow, Null Pointers, Buffer Overruns):
5938 (Floating Point Portability, Exiting Portably): New sections.
5939 (Writing Test Programs): Fix some langauge. Recommend exiting
5940 with status 1, not merely nonzero. Clarify exit declaration.
5941 (Run Time): Move C exit status stuff to new Exiting Portably section.
5942 (Systemology): Mention Posix and levenez. Update v7 reference.
5943 (Portable Shell): Mention the Posix shell.
5945 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5947 * bin/autoconf.as (me): Replace by as_me.
5949 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5951 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5952 since as_me isn't set yet.
5954 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5956 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5957 a few minor bugs in this area.
5959 * doc/autoconf.texi (Programming in M4sh): Comment out the
5960 documentation of AS_BASENAME, for now.
5961 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5962 (Limitations of Builtins) <basename>: Do not refer to
5964 * bin/autoconf.as (me): Don't use AS_BASENAME.
5965 (dir): Remove the unused variable.
5966 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5967 AS_DETECT_REQUIRED. All uses changed.
5968 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5970 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5971 (AS_BASENAME): Use "basename --" to protect against leading "-".
5972 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5973 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5974 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5975 (_AS_DIRNAME_PREPARE): Likewise.
5976 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5977 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5978 (AS_DIRNAME): Use "dirname --".
5980 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5982 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5983 of "run time" and "run-time" changed to "runtime", for consistency.
5984 * lib/autoconf/fortran.m4: Likewise (in comment).
5985 * lib/autoconf/functions.m4: Likewise.
5986 * lib/autoconf/general.m4: Likewise.
5987 * lib/autoconf/headers.m4: Likewise.
5989 * doc/autoconf.texi (Run Time): Document the exit status situation
5990 with more accuracy and detail.
5992 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5994 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5995 Archive is not officially `GNU' any more. Update URL.
5996 (Defining Directories): Likewise
5997 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5999 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6001 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6002 newline from the `trap' code to finish `config.log'; the NetBSD
6003 /bin/sh resets the exit status after an empty command, as
6004 documented in doc/autoconf.texi.
6005 Reported by Dalibor Topic <robilad@kaffe.org>.
6007 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6009 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6010 Suggested by Bruno Haible.
6012 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6014 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6015 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6016 Instead, just list the shells that we know work.
6017 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6018 changed. Be more cautious about the _cv_ variable.
6019 * tests/tools.at (Syntax of the shell scripts): Check the
6020 _cv_ variable once, at first, to avoid an internal autoconf error
6021 when sh -n does not work.
6023 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6025 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6027 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6029 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6030 use ">&-" since we're only 99.999% sure that this is portable,
6031 and since the MinGW bug is fixed in a different way.
6032 * lib/autotest/general.m4 (AT_INIT): Likewise.
6034 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6036 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6037 before opening config.log, to avoid hitting a bug on MinGW.
6039 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6041 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6042 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6043 This works around a MinGW bug reported by Eric Paire.
6044 Make sure that all writes to the log file append to it,
6045 rather than possibly losing data.
6046 * lib/autotest/general.m4 (AT_INIT): Likewise.
6048 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6050 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6053 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6057 * configure.ac (AC_INIT): Bump to 2.59d.
6059 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6063 * Makefile.maint (news-date-check): Do not require a leading `*'
6064 before the release date in NEWS.
6066 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6067 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6069 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6070 the instantiated file do not contain the string 'datarootdir'
6071 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6072 @mandir@, replace the reference '${datarootdir}' by the value.
6073 * tests/torture.at (datarootdir workaround): New test.
6074 * NEWS: Advertise this temporary fixup.
6075 Based on a patch by Bruno Haible, reported and analyzed by
6076 Paul Eggert and Noah Misch.
6078 2006-04-12 Eric Blake <ebb9@byu.net>
6080 * tests/autotest.at (Debugging a failed test): Fix comment.
6082 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6084 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6085 all the changes since 2006-04-07.
6087 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6089 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6090 succeeded, but `ln -s file dir' failed, take care to remove the
6091 leftover target before the next test, to prevent its spurious
6092 failure; also make sure `ln file dir' works before selecting it.
6093 Thanks to Keith Marshall for pointing this out.
6096 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6097 assignments in `at_debug_args', so that we put them correctly
6098 in the `run' script.
6099 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6100 Reported by Eric Blake.
6102 2006-04-11 Eric Blake <ebb9@byu.net>
6104 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6105 top-level tests after micro-suite has been run. Used in...
6106 (Debugging a successful test, Debugging script and environment),
6107 (Debugging a failed test): ...these new tests. The first of these
6109 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6110 macro, split out from...
6111 (AT_INIT): ...here, so that using -d also generates a run script.
6112 Document that -d inhibits top-level logging.
6113 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6114 inhibits top-level logging; debug scripts are created.
6116 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6118 * tests/autotest.at (Empty test, Empty check): New test to check it.
6120 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6123 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6125 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6126 the files if a problem appears. Make the empty *.at files
6127 read-only, too. Proposed by Ralf Wildenhues.
6129 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6131 * config/Makefile.am: Add comment to force updated Makefile.in.
6133 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6134 space only patch to this file, this patch causes the Makefile.in
6135 files that include freeze.mk to be updated, and thus have a
6136 newer time stamp again, which in turn makes a pristine CVS
6137 checkout have correct time stamps.
6139 * Makefile.maint (cvs-sv): New macro, to be used..
6140 (config.guess-url_prefix, config.sub-url_prefix)
6141 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6142 point to CVS text checkout of Gnulib files.
6143 (copyright-check): Bump current year.
6144 (announcement): Do not hard-wire `./announce-gen'.
6145 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6147 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6149 (wget_files): Update config.guess, config.sub, texinfo.tex by
6150 `wget-update', now that their URLs work again.
6152 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6154 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6155 Problem noted by Paul D. Smith.
6157 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6159 * doc/autoconf.texi: Remove unused words from word list.
6160 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6161 .x-sc_trailing_space: New files.
6163 * doc/standards.texi: Sync from gnulib.
6165 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6166 `LIBOBJDIR' as experimental.
6168 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6169 with a target directory; it's internally implemented as `cp'
6170 anyway, but since Autoconf advertises the possibility to use
6171 a target directory when LN_S is `ln -s', we need to find out.
6172 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6173 analyzed by Keith Marshall <keith.marshall@total.com>.
6177 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6179 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6180 confdefs.h as-is. In general, if it has backslash-newline or the
6181 like, then it doesn't work either to sort or to remove empty
6184 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6186 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6188 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6190 * lib/autom4te.in (Automake-preselections): Preselect
6193 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6195 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6196 apostrophe within a single-quoted string, as this is the usual
6197 tradition and is easier to read than '"'"'. Don't rely on the
6198 shell treating "$/" like '$/'. Use a more-consistent indenting
6201 2006-04-09 Eric Blake <ebb9@byu.net>
6203 * tests/autotest.at (Backquote command substitution),
6204 (Multiline backquote command substitution): Remove mistaken
6205 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6207 (Parenthetical command substitution, Multiline parenthetical
6208 command substitution): here.
6210 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6212 Import macros from gnulib (often changing their name).
6214 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6215 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6216 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6222 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6223 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6224 The manual mentions Gnulib more prominently.
6225 * doc/autoconf.texi (Gnulib): New node.
6226 (Pointers): Add Gnulib URL.
6227 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6228 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6230 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6231 suggest a #define rather than a typedef for _Bool, and mention
6232 Gnulib rather than trying to substitute stdbool code.
6233 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6234 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6235 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

6304 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6305 test case by Noah Misch <noah@cs.caltech.edu>.

6341 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6343 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6344 whether `set' quotes correctly: redirect stderr of the tested
6345 `set', and use a subshell, for Ultrix; use `sed' instead of
6346 `grep' for zsh `set' which may write binary output; match only
6347 at the beginning of a line, to avoid false positives.
6348 In order to avoid false positives by unrelated variables with
6349 multiline content, put the dump algorithm in a subshell and
6350 unset all variables containing newlines (except some which are
6351 special to the shell). Warn about cache variables that are

6397 ac_config_<foo>s again, sometimes normalized, sometimes not.
6398 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

6400 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6401 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6402 2005-07-25 rewrite. Noticed by Noah Misch.
6404 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6405 _AC_PRESERVE_HELP_ORDER, ...

6412 for --help from Cygnus `configure.'
6414 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6466 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6467 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

6558 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6559 initial `rm' of the candidate files...
6560 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6561 the same list in subsequent `rm' calls, and for the temporary

6564 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6565 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6566 no longer needed) by libtool. Make it a cache check.

6645 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6646 switch all of them on and of when necessary. Fixes the bug when
6647 m4sugar macros (e.g., m4_define) were expanded after the first
6648 automatic update (e.g., after AC_PREREQ or AC_INIT).

7196 (Particular Programs): Likewise.
7197 (Coding Style): y is like s with respect to / and ,.
7198 (Limitations of Usual Tools): Document the weird restrictions
7199 that Posix has about { }. Use better quoting.

7287 Factor functionality to..
7288 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7289 `AC_SUBST($1)' in the public version.
7290 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7291 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7316 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7317 conftest.o, to see whether the compiler really obeys; rm the object
7318 file before and after the test and register it with ac_clean_files.

7342 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7343 the inner workings of AC_LANG_FUNC_LINK_TRY.
7344 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7345 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7346 by the function rather than ignoring it.
7347 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7348 comparing its address. Intel's interprocedural optimization was
7349 outsmarting the old heuristic. Problem reported by
7352 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7354 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7356 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7358 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7359 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7361 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7363 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7364 before removing it (chmod -R u+rwx); there are three instances of this.
7366 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7367 Stepan Kasal <kasal@ucw.cz>
7369 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7370 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7371 make its content writable before removing it. Remove an errorneous
7372 comment from the end, where the logs of the failed tests are copied
7373 to the main log file.
7375 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7377 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7378 in case the computer is too quick. Double quote the configure.ac
7381 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7382 problems if the testsuite were running too fast.
7384 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7386 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7387 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7388 (which belong to Xt, not X itself). See Debian bug 327655.
7389 * NEWS: Mention this.
7391 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7393 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7395 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7397 * config/move-if-change: Don't output "$2 is unchanged";
7398 suggested by Ben Elliston. Handle weird characters correctly.
7400 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7402 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7403 calls, so that the final expansion of this macro is shorter.
7404 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7405 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7406 the cleanup there. Use AS_VAR_* macros, to be more general.
7407 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7409 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7411 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7413 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7415 * doc/autoconf.texi (Configuration Headers): Add an index entry
7418 2005-08-26 Pavel Roskin <proski@gnu.org>

7421 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7424 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7426 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7427 The previous patch didn't work, so try a better one.
7429 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7431 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7432 in the example. Reported by Bruno Haible.
7433 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7434 "if $undefined_var;" succeeds with my shell.
7436 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7437 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7438 but change the m4_divert_text to m4_divert_once.
7440 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7442 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7443 Work around bug in Solaris /usr/xpg4/bin/awk.
7444 The bug is present in at least Solaris 8 through 10.
7446 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7448 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7449 some evil values and relying on the fact that $* concatenates the
7450 parameters by the first character from IFS.
7452 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7453 Stepan Kasal <kasal@ucw.cz>
7455 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7456 first header appears, define AH_HEADER.
7457 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7458 Update limitations about when to call AC_CONFIG_HEADERS.
7459 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7460 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7461 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7462 ``Configuration Actions''; fix their index entries.
7464 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7465 options correctly. Process N-M as M-N if M is smaller than N.
7466 Process ranges correctly so that N-N will run only N.
7467 Sort and uniquify the tests that will be run. If there is more
7468 than one test, reinsert the banners for the tests.
7469 * tests/autotest.at (Keywords): Unmark XFAIL.
7471 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7473 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7474 before passing the macro name to AH_TEMPLATE.
7476 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7477 now opens log after option processing; in particular, --version
7478 and --help do not touch config.log.
7480 * Makefile.maint: Revert the change from 2005-08-12.
7482 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7484 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7486 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7488 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7490 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7491 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7494 * doc/autoconf.texi (Defining Symbols, Changed Results):
7495 Prepend to LIBS, not append, in examples.
7497 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7499 When building in place, set srcdir="."; suggested by Tim Van Holder.
7501 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7502 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7503 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7504 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7505 does not mean "no --srcdir option".
7507 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7509 * tests/autoscan.at (autoscan): New file.
7510 * tests/suite.at: Use it.
7511 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7512 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7514 * tests/autotest.at (Keywords): Test keywords combinations.
7516 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7518 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7519 add "2>&1"; gzip 1.2.4 prints help on stderr.
7521 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7523 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7524 was pushdef'ed twice while popped only once. Push it only once.
7525 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7527 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7529 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7530 prefixed by mere "===", not "configure: === ".
7532 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7534 * Makefile.maint: Update from Bison.
7536 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7537 "<tab>" in comment, so that the point is understandable.
7539 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7541 Rewrite substantial part of lib/autoconf/status.m4.
7542 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7543 and CONFIG_COMMANDS are not processed in four separate loops.
7544 Instead, there is one main loop. This alows that the common code
7545 is expanded only once, thus config.status (and configure) is smaller.
7547 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7548 the AC_LIST_FILES and cousins macros are no longer used.
7550 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7551 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7552 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7553 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7554 contain the initialization, nor the for loop, nor the associated
7555 commands; all these go to ...
7556 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7557 _AC_OUTPUT_CONFIG_STATUS.
7558 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7559 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7560 (_AC_OUTPUT_FILE): The creation of the sed script ...
7561 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7562 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7563 _AC_OUTPUT_MAIN_LOOP.
7564 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7565 _AC_CONFIG_COMMANDS): Use ...
7566 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7567 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7568 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7569 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7570 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7571 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7573 (_AC_CONFIG_UNIQUE): Update.
7574 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7575 Replaced by this ...
7576 (_AC_LIST_TAGS): ... new common macro.
7577 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7578 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7579 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7580 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7581 this didn't belong to the `config commands' section.
7582 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7583 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7584 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7585 to the `config commands' section either.
7586 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7587 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7589 ... and many changes to the comments nearby.
7591 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7592 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7593 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7594 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7595 (#define header templates): The comment at the top of the generated
7596 header now includes the name(s) of the source file(s).
7598 Several unrelated small changes:
7600 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7601 parameter to AC_DIAGNOSE.
7602 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7603 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7604 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7605 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7607 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7608 in AC_OUTPUT doesn't double-quote it either.
7609 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7612 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7614 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7615 versions of Portland Group compiler produce single- and double-quoted
7616 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7617 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7619 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7621 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7622 This is a corrected version of yesterday's patch.
7624 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7626 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7627 path, too; insert a "===" to emphasize the line.
7629 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7630 ac_cv_build_alias to ac_build_alias.
7631 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7633 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7634 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7635 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7636 (AC_ARG_VAR): ... here.
7637 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7640 Keep a list of all precious variables and process them with one simple
7641 for loop, instead of expanding all commands, or, OTOH, complicated

7777 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7798 variable into diagnostic. Make the diagnostic an error, not a warning,
7799 because we really don't support spaces and suchlike in dir names.
7800 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7801 Don't worry about backslashes in srcdir; it can't happen now.

7845 * doc/autoconf.texi:
7846 Don't mention Solaris versions so much, if a
7847 problem is common to all extant versions of Solaris. Say "SunOS
7848 4" instead of "SunOS" for SunOS 4.
7849 (awk): Mention more of the limitations of traditional Awk.

7892 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7893 -u, since it outputs chatter if the input files are the same.
7894 Problem reported by Ralf Menzel.
7896 2005-06-08 Derek Price <derek@ximbiot.com>
7898 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7899 renaming them since they are about to be redefined anyhow.
7901 2005-06-08 Derek Price <derek@ximbiot.com>
7903 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7904 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7905 Move m4_undefine to alphabetical order.

7910 * doc/autoconf.texi (Introduction): Likewise.
7911 Reword to avoid some formatting glitches.
7912 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7913 Clarify explanation of HP compiler bug.
7914 Redo example output tp match current CVS snapshot.
7915 Use @example.org in email addresses when the examples
7916 might get inadvertently cut-and-pasted into user code.
7917 Remove example of autom4te usage that doesn't seem to work now.
7918 Use modern AC_INIT (except when the example is meant to be
7919 shown with Autoconf 2.13).
7920 Update ksh info for Solaris 9 and later.
7922 Modernize description of Automake versions a bit.
7923 Don't claim a future version of Autoconf is near.

7933 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7934 Tru64 ksh pattern matching bug. Reported against Libtool by
7935 Albert Chin <libtool@mlists.thewrittenword.com> and
7936 Nicolas Joly <njoly@pasteur.fr>.
7938 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7940 m4_cdr of one-member list was [[]] (one-member list containing an
7941 empty string) instead of [] (an empty list. Callers were skewed to
7942 match this misbehaviour. As a consequence of this:
7943 - m4_foreach([x], [], [foo]) expanded to `foo', while
7944 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7945 This bug has been fixed:
7947 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7948 expand to an empty string; print error msg if called without
7950 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7951 misbehaviour; handle [] and [[]] correctly.

7961 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7962 swallow records with more than 99 fields.
7963 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7964 parse the long line.
7966 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7968 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7969 swallow literals longer than 399. Reported by Ralf Wildenhues.

7981 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

8003 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8004 now contain newlines, and substituted files must be referenced on
8005 a line alone; the sed scripts to substitute them are now very

8008 commands can be put in a sed script portably.

8164 quoting rules. Problems noted by Stepan Kasal.
8165 Also, throughout this document, be more careful about white space.
8166 "blank", "white space", and "space" all have different meanings
8167 and we should be careful to say what we mean.

8188 set by latest automake.
8190 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8192 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8193 outputs 0 on GNU/Linux these days.

8203 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8206 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8207 by AC_DEFINE; it was a mistake.
8208 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8210 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8212 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8214 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8216 * doc/autoconf.texi (External Software): Quadrigraphs are not
8217 processed correctly in AS_HELP_STRING; avoid this in the examples.
8218 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8219 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8220 comment and reduce m4_default([foo], []) to [foo].
8221 (m4_strip): Update the explanation.
8223 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8225 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8226 Remove core.conftest.* too; it's generated by Tru64 5.1.
8227 Problem reported by Jennis Pruett.
8228 * lib/autoconf/functions.m4
8229 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

8279 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8280 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8281 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8283 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8285 * NEWS: The configure command now warns you if you attempt to use
8286 a directory whose name contains a special character like space,
8288 * doc/autoconf.texi (Installation Directory Variables): Allow
8289 "," in file names. Do not use \@; it's not a portable regexp.
8290 * bin/Makefile.am (edit): Likewise.
8291 * lib/Makefile.am (edit): Likewise.
8292 * tests/Makefile.am (edit): Likewise.

8298 unportable file names.
8299 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8301 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8302 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8303 ac_pwd, and quote srcdir.
8304 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8306 * doc/autoconf.texi: Fix some systematic formatting problems.
8307 ".)" needs a following @: if not at the end of a sentence, and
8308 similarly for "!)". "etc." should be preceded by a comma.
8309 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8311 2005-03-22 Bruno Haible <bruno@clisp.org>
8313 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8314 argument is often called 'build-aux'.
8316 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8318 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8319 macro AC_TRY_LINK is obsolete.
8320 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8323 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8325 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8326 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8327 from a Common Lisp's `cl'.
8328 (AC_PROG_CXX): Behave according to the documentation: don't
8329 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8330 make the variable CCC precious; use `cl.exe', not `cl'.
8332 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8333 Alexandre Duret-Lutz <adl@gnu.org>
8335 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8336 /dev/null, as "configure" shouldn't read stdin, and this insulates
8337 us from problems (e.g., when testing for "cl"). Also, do this
8338 redirection before invoking "hostname" or "uname", and keep the
8339 original input stream available via...
8340 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8341 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

8353 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8354 newline if neither \c nor -n work, as that would output two
8355 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8357 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8359 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8360 This causes that any required macros inside will get before the if.
8361 * doc/autoconf.texi (autom4te.cache): A typo.
8363 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8365 Undo previous change, except keep the change to
8366 lib/autoconf/programs.m4 that replaced grep with shell
8367 pattern-matching. This is because net-snmp configure reads stdin.
8368 Reported by Noah Misch.
8370 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8372 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8373 from /dev/null, as "configure" shouldn't read stdin, and this
8374 insulates us from problems (e.g., when testing for "cl").
8375 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8376 before invoking "hostname" or "uname".
8377 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8378 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8379 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8380 "</dev/null" since it's now done at the top of 'configure'.
8381 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8382 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8383 Also, replace grep with shell pattern-matching, to save a process.
8385 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8387 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8388 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8389 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8392 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8394 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8395 grep -q isn't portable. Improve grep -s explanation.
8396 Problem reported by Dan Manthey.
8398 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8400 * doc/autoconf.texi (Special Shell Variables): Clarify
8401 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8403 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8405 * doc/autoconf.texi: Use @acronym for DJGPP.
8406 Fix some @code's that should have been @env's, and vice versa.
8407 Sort environment variable names.
8408 Mention that shells no longer inherit IFS.
8409 Don't recommend PATH_SEPARATOR=';' so strongly.
8410 Mention that $RANDOM might expand to the empty string.
8411 "symlink" and "soft link" -> "symbolic link".
8412 Improve mktemp description (reported by Bruno Haible).
8414 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8416 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8417 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8419 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):

8424 * NEWS: Mention AT_COPYRIGHT.
8426 * tests/local.at (AT_CMP): Use diff directly on input files rather
8429 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8430 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

8433 and Paul Eggert <eggert@cs.ucla.edu>
8435 * tests/autotest.at (Empty test suite): New test.

8445 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8446 (Standard regular expressions): New test.
8447 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8448 excess test name quoting.
8449 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8450 CPPFLAGS to `configure' instead of setting it in `configure'.
8452 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8453 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

8487 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8488 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8490 Try not to generated lines of unlimited length, as POSIX places a
8491 2047-byte limit on line length of portable text files.
8492 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8493 Use newline as a separator, not space.

8506 * doc/autoconf.texi (Special Shell Variables): Mention _,
8507 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8508 if they contain a lower-case letter. The DUALCASE problem was
8509 reported by Ralf Wildenhues.
8511 * bin/autoconf.as: Don't exit with status 0 after write failure
8512 with --help or --version.

8526 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8527 care to echo the commands, so the user knows what's going on.
8528 Modified from a suggestion by Stepan Kasal.
8530 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

8551 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8552 Update the long comment explaining it.
8554 m4_require no longer writes an ``is required by'' line to the
8555 execution stack. It contains only one bit of non-redundant
8556 information: that the macro was required, not called. And even

8980 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8981 "char c = '\200';" rather than "char c = 0x80;" as the

9042 simplify the examples and improve their quoting.
9044 2004-11-13 Stepan Kasal <kasal@ucw.cz>
9046 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9047 the $1_found variable, don't test whether the file is executable;
9048 Both things are checked ...
9049 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
9050 the former ``test -f''.
9051 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
9053 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

9065 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9066 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9067 variants", "Unix", and some related minor wording fixups.
9069 (Shellology, Special Shell Variables): Document that the Zsh
9070 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9071 to Alexandre Duret-Lutz for this info.

9080 of putenv. Problem reported by Michael Wardle.
9082 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9084 * doc/autoconf.texi (auindex): New macro.
9085 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9086 Problem reported by Stepan Kasal.

9092 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9094 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9095 readable; it's not true in OS/2-emx.
9097 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9099 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9100 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9101 (trivial change). Problem and patch reported by Andrew Church in:
9102 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

9131 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9132 texinfo.tex for now (done by hand now).
9133 * Makefile.maint (wget_files, cvs_files):
9134 Remove ansi2knr.c; nobody uses it.
9135 (ansi2knr.c-url_prefix): Remove.
9136 (cvs-update): Fix test for failure. I don't know why it ever
9139 * doc/autoconf.texi: Update URLs, some of which went stale.
9140 Use @uref rather than @href.
9142 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9143 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9145 * config/config.guess, config/config.sub, config/elisp-comp,
9146 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9147 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9149 * NEWS, TODO, configure.ac, bin/autoscan.in,

9155 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9156 tests/tools.at, tests/torture.at:
9157 Use "file name" rather than "filename" or "path",
9158 to be consistent with the terminology of the GNU coding standards.
9160 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9162 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9163 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9164 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9165 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9167 More fixes to support spaces in the name of the build directory.
9168 This isn't a complete fix but it's an improvement.
9170 * bin/autoconf.as (autom4te_options): New var.
9171 Use it instead of appending to AUTOM4TE, so that we can allow
9172 spaces in the build directory's absolute name.
9173 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9174 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9175 AT_CHECK_NOESCAPE): Likewise.
9176 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9177 main program): Likewise.
9179 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9181 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

9187 * doc/autoconf.texi (Function Portability): Document isinf and
9188 and isnan. From a suggestion by Kevin Ryde.
9190 * lib/Autom4te/General.pm (END): Return correct exit status even
9191 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9193 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9195 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9196 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9197 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9199 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9201 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9202 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9203 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9204 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9205 * lib/autom4te.in (Automake-preselections): Preselect
9206 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9208 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9210 * lib/autom4te.in (Automake-preselections): Preselect
9211 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9214 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9216 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9218 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9219 Document problem with "`""`" in pdksh POSIX mode.
9221 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9223 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9224 with pdksh, too. Problem reported by Patrick Welche via
9226 * doc/autoconf.texi (Shellology): Note that set -o posix is
9227 useful for pkdsh, too.
9229 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9231 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9232 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9233 Don't fail if ENV or BASH_ENV is readonly.
9234 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9235 etc. are read only. Problem reported by Ludovic Courtes.
9237 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9239 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9240 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9243 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9245 * doc/autoconf.texi (File System Conventions): Warn about
9246 names like "aux". Problem reported by Eric Blake.
9248 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9249 by zero instead of array size, so that we can use any arithmetic
9250 constant expression (instead of requiring an integer constant
9251 expression). This allows us to test expressions like DBL_MAX <
9252 LDBL_MAX, which didn't conform to the C standard using the old
9254 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9255 now that we can do floating-point tests at compile time.
9257 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9259 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9260 and LDBL_EPSILON, as the resulting expression isn't an
9261 integer constant expression and violates the C standard.
9262 Problem reported by Nelson H. F. Beebe. Also, check
9263 for "L" suffix, and check that long double doesn't have
9264 worse range or precision than double, that mixed-mode
9265 arithmetic doesn't generate a diagnostic, that double
9266 constants fit in long double.
9268 2004-06-03 Kevin Ryde <user42@zip.com.au>
9270 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9271 malloc(0) and realloc(NULL,size).
9273 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9276 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9278 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9279 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9282 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9284 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9285 can be rewritten using if-then-else. Suggested by Bruno Haible.
9287 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9289 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9290 Problem reported by Stepan Kasal.
9292 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9294 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9295 change). Patch reported by Ralf Wildenhues in
9296 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9298 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9299 function F exists if the compiler and linker let you compile an
9300 expression like (F != 0). Recent versions of GCC optimize away
9301 the reference to F in that case, since every function address must
9302 be nonzero, so the link succeeds even if F does not exist.
9303 Problem reported by Manu in
9304 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9306 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9307 "Unix". Many uses changed.
9308 (Limitations of Builtins): Explain better why the ! command isn't
9311 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9313 * lib/autom4te.in (Automake-preselections): Preselect
9314 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9316 2004-05-19 Kevin Ryde <user42@zip.com.au>
9318 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9319 referencing AC_FUNC_STRERROR_R.
9321 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9322 note pessimistic assumption when cross compiling.
9324 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9326 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9327 (until 2004) invoked subcommands with sh -e, contra POSIX.
9328 Reported by Kevin Ryde.
9330 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9332 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9333 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9334 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9335 `test -f " /usr/bin/grep"', which _always_ failed.
9336 (AC_PROG_SED): Ditto bogus PATH fix.
9337 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9338 requires that grep correctly supports _multiple_ `-e' options, rather
9339 than stating only that grep should accept `-e'.
9341 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9343 Port to C99, which requires that 'exit' be declared.
9345 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9346 to ensure that stdlib.h is included.
9347 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9348 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9349 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9350 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9351 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9352 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9353 when using 'exit' in a test; C99 requires that 'exit' be declared.
9355 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9357 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9358 now prefers 'grep' implementations that accept -e.
9359 (Limitations of Usual Tools): Describe problems of traditional
9360 egrep and fgrep with long input lines, and of traditional grep
9362 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9363 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9364 All callers changed. Append /usr/xpg4/bin to the PATH, for
9366 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9367 the user with complaints about multiple -e options.
9368 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9369 Define it with AC_PROG_GREP.
9370 * configure.ac (AC_PROG_GREP): Add.
9371 * lib/freeze.mk (GREP): New macro.
9373 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9375 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9376 a possible candidate only after all others fail, rather than
9377 consulting it first. This improves backward compatibility by
9378 better reflecting the way shell selection occurred in previous
9379 versions of Autoconf, and should help to avoid triggering latent
9380 problems in other packages, such as the one in Automake where zsh
9381 is not handled robustly:
9382 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9383 Although it is not Autoconf's responsibility to work around
9384 problems in Automake, it nevertheless makes sense to avoid
9385 introducing unnecessary incompatibilites.
9387 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9388 Gary V. Vaughan <gary@gnu.org>
9390 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9391 how deeply nested we are when a suitable tool is found, set the
9392 ac_path_TOOL_found flag.
9393 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9394 nested we are in this macro. Break out of all 3 nested loops if
9395 ac_path_TOOL_found is set.
9397 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9399 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9400 of the _AS_PATH_WALK loop too if GNU flavor is found.
9402 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9404 * doc/autoconf.texi (Limitations of Make): Update documentation
9405 for `$<'. New entry `Long lines', based on a report from Simon
9406 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9407 paragraph about DJGPP, based on a mail from Richard Dawe.
9409 2004-04-20 Paul Eggert <eggert@twinsun.com>
9411 * tests/c.at (C keywords): Don't assume that GCC supports
9412 "restrict" and "inline", as sufficiently-old GCC versions do not
9413 (also, GCC configured to be in pedantic C89 mode does not).
9414 Problem reported by Sumit Pandya in:
9415 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9417 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9418 consider -g to work if it generates warnings when plain compiles
9419 don't. Problem reported by Braden McDaniel in:
9420 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9422 * doc/autoconf.texi (Slashes): New section, to document a problem
9423 reported by Jim Meyering in:
9424 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9426 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9427 linker output files before linking, to work around IRIX 6 linker bug.
9428 Problem reported by Rainer Orth in:
9429 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9431 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9433 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9434 best tool so far counter rely on the tool path variable name to
9435 avoid checks for one tool being affected by the results of running
9436 the length check on a previous tool.
9438 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9439 match expression argument, as different greps have different
9440 regular expression flavours.
9441 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9443 (AC_PROG_EGREP): Pass 'EGREP$'.
9444 (AC_PROG_GREP): Pass 'GREP$'.
9446 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9448 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9449 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9451 2004-03-29 Paul Eggert <eggert@twinsun.com>
9453 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9454 Types, Specific Compiler Characteristics, System Services,
9455 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9456 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9457 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9458 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9460 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9461 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9462 AC_TYPE_OFF_T): Likewise.
9463 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9466 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9467 pacify libtool 1.5.2. Fix quoting problems in sed command.
9469 2004-03-28 Paul Eggert <eggert@twinsun.com>
9471 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9472 now defines HAVE_DECL_TZNAME if it is declared, when
9473 HAVE_STRUCT_TM_TM_ZONE is not defined.
9474 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9475 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9478 2004-03-28 Steven G. Johnson <stevenj@fftw.org>

9546 Problem reported by Anthony N. Frasso in
9547 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

9564 problem on QNX reported by Stephen Rasku in

9576 AC_SUBST provides no portable way to escape literal newlines.
9578 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9579 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9580 Darwin uses -lcrt2.o and there's little point to cataloging all
9581 the system variants. Partial fix reported by Andreas Waechter in:

9606 Eric Sunshine <sunshine@sunshineco.com>

9609 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9657 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9658 2003 (except 1997) to the list of copyright years. This undoes
9659 the 2003-05-22 change, which removed the older years from the list.
9660 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

9673 _AC_PROG_GREP, and AC_PROG_SED.

9706 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9707 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9708 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9709 not <inttypes.h>. Problem reported by Tim Mooney in
9710 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9711 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9714 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9715 otherwise "make check" fails because it forbids cmp (I guess
9716 because cmp treats files as binary on DOS-like systems).

9719 have changed in 2004.

9729 2004-01-15 Paul Eggert <eggert@twinsun.com>
9731 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9732 -std1 disables some useful extensions on Tru64. Problem reported

9736 2004-01-14 Paul Eggert <eggert@twinsun.com>
9738 * doc/autoconf.texi (Programming in M4sh): Document that
9739 AS_MKDIR_P succeeds if the destination is a symbolic link
9740 to an existing directory.
9741 (Limitations of Usual Tools): Note that mkdir -p might not
9742 succeed on symlinks to directories.
9744 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9746 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9760 2004-01-09 Paul Eggert <eggert@twinsun.com>
9762 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9763 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9764 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9765 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9766 AC_COMPILE_IFELSE, since we now assume our caller invokes
9767 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9768 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9769 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9770 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9772 2004-01-07 Paul Eggert <eggert@twinsun.com>
9774 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9775 `"'...'"`, as it's confusing (and I suspect it may not work on
9776 some platforms). The code was incorrect anyway, as it assumed
9777 that \$ evaluated to itself in that context. Reported by
9778 Alexandre Duret-Lutz.
9780 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9782 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9812 Bug reported by David Relson in
9813 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9815 * Makefile.am (autom4te-update):
9816 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9832 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9833 -c -o might not work. From a suggestion by Kevin Ryde.
9834 (C Compiler, Generating Sources, Limitations
9835 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9836 Don't put '-o' after non-options, as POSIX doesn't allow this.
9837 Mention that cc's name might be gcc or c89 or whatever.
9839 2004-01-04 Kevin Ryde <user42@zip.com.au>

9848 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9850 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9851 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9852 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9853 explanation clearer.

9953 2003-11-15 Kevin Ryde <user42@zip.com.au>
9955 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
9956 than $target since the latter is not usual, add guidelines on when to

10116 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
10119 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
10121 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official

10134 Problems reported by Eric Sunshine.
10136 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10138 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10139 -mGLOB_options_string stuff for Intel ifc, which can cause

10163 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10164 cache variable instead of $G77 to decide whether to include -O2,
10165 since $G77 is specific to Fortran 77.

10169 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10170 free" flag. Re-order flags tested into rough order of popularity.
10172 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10174 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10175 arguments so that it can be used with syntax identical to
10176 AC_PROG_F77, and so that we can more easily decide to
10177 remove/deprecate the DIALECT optional argument in the future if it
10178 proves troublesome.
10179 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10180 non-freeform-supporting compilers. Document freeform flags.
10182 2003-10-03 Akim Demaille <akim@epita.fr>

10244 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10245 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10246 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10247 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10249 2003-09-26 Akim Demaille <akim@epita.fr>
10251 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10252 directory for AC_CONFIG_COMMANDS' first argument exists.
10253 This makes valid the invocation of _AC_SRCPATH that follows.
10254 Reported by Eric Sunshine.
10255 * doc/autoconf.texi (Configuration Commands): Adjust.
10257 2003-09-26 Akim Demaille <akim@epita.fr>

10278 The test suite are sometimes assigning timings incorrectly.
10279 Reported by Henk Krus.
10280 Diagnosed by Nicolas Joly.
10282 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10284 Instead of making AT_help a sequence of assignments to grow
10285 $at_help_all, just make AT_help_all be the growing contents of
10286 $at_help_all, and make a single assignment in...
10288 (at_times_skip): Flip the meaning and rename as...
10289 (at_times_p): this.
10290 (AT_INIT): When summarizing the test that ran, remove
10291 $at_times_file after use, and check it is present before trying to

10300 (ifnames): chmod -w.
10301 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10302 executables, not bin/ executables! Otherwise all the magic needed
10303 to find non installed files is turned off. This caused a failure
10304 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10305 as found in its environment (sent by tests/autoreconf): pointing
10306 to bin/autom4te that could not find its files.
10307 * tests/mktests.sh: Force the replacement of generated files, for
10308 the sake of "mv" program that are interactive when overwriting a
10310 * config/install-sh: Upgrade from CVS Automake.

10317 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10318 Paul Eggert <eggert@twinsun.com>
10320 Trivial change to support GCC's configuration procedure.

10322 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10323 about inconsistency if the preprocessor is set to give errors for

10356 willing to edit the output files.
10358 2003-09-10 Akim Demaille <akim@epita.fr>
10360 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10361 and AC_FC_FREEFORM.
10362 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10363 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

10383 2003-09-05 Paul Eggert <eggert@twinsun.com>
10385 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

10403 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10405 Add support for newer Fortran dialects. The F77 interface is
10406 unchanged, and continues to support Fortran 77. New FC macros
10407 correspond to all the old F77 macros, with output variables FC,
10408 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10409 available dialect, but older dialects can be specified. There are
10410 new macros AC_FC_SRCEXT to set the source extension, and
10411 AC_FC_FREEFORM to accept free-form source files.
10413 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

10537 2003-08-21 Akim Demaille <akim@epita.fr>
10539 First stab at preserving warnings between calls to autom4te,
10540 including when the cache is used.
10542 There are still several issues: (i) there are too many runs of m4
10543 (one for include, one for warnings, and some more), (ii) warnings
10544 spreading on several lines are not handled gracefully, (iii) the
10545 code meant to have the call stack display for errors does not work
10546 (its handling should move from m4 to autom4te).
10548 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10550 (@preselect): Add m4_warn.
10551 ($exit_status): Remove, use $exit_code.
10552 ($help): Use Autom4te::ChannelDefs::usage.
10553 (&handle_m4): No longer define the m4_warnings.
10554 At each run, extract and report the warnings.
10555 Always cache the result, including if the exit status is on
10556 failure, since if nothing changes, we should result in the same
10557 failure, hence we can use the cache.
10558 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10559 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10561 (m4_warn): Redefine as a do-nothing: it is its invocation that
10562 matters, as warnings are now reported via traces.
10563 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10564 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10565 the latter reveals calls to the former.
10569 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

10602 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10603 * bin/autom4te: Adjust.
10604 In particular, be Autoconf tools are really silent when properly
10605 working, bind the verbosity of the 'note' channel to $verbose.
10606 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

10730 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10731 not all of them. This fixes 1. the fact that when testing
10732 Autoconf there are many many config.log, 2. the incorrect use of
10733 top_srcdir to find config.log.
10734 Don't mix the detailed output of failed test with the summary of
10735 failures. Rather, append detailed log afterwards.
10737 2003-06-23 Akim Demaille <akim@epita.fr>

10854 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10855 Remove `#include <stdlib.h>' from the list; we should never
10856 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10857 resulting namespace pollution would cause other tests to fail.
10858 Configure scripts run with some older versions of g++ and HP's
10859 aCC would fail due to such an #include. Problems reported by
10860 Matthew Mueller in <http://bugs.debian.org/120704> and by
10862 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10863 In the test, use the test declaration before including <stdlib.h>,
10864 as that's closer to how it'll be used.

10871 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10873 Overhaul Autotest's logging: generate separate log files
10874 in testsuite.dir/NNN/testsuite.log, and append them to
10875 testsuite.log instead of re-running the test verbosely.
10877 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10878 file descriptor, write 0 to at_status_file instead of setting
10879 at_status=0, initialize some new variables (at_status_file,
10880 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10881 to rerun the tests, instead append the at_group_log to the
10882 at_suite_log when a test fails.
10883 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10884 with the AS_MESSAGE_LOG_FD redirected to stdout.
10885 (AT_CLEANUP): save the output status in $at_status_file
10886 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10887 its original place.
10888 (AT_CHECK): since tests are run with a redirected stdout,
10889 and used to be re-run in verbose mode, turn some $at_verbose
10890 into echo, and don't redirect the output of testing stdout

11014 2003-05-06 Akim Demaille <akim@epita.fr>
11016 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11017 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11018 by aclocal.m4 is changed it might require the importing of another
11019 m4 extension file, i.e., aclocal must be run.

11272 innocuous variant befor including <limits.h> or <assert.h>. This

11275 gettimeofday and many other functions.

11292 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11293 defined, to support freestanding compilers. This should fix the
11294 bug reported by Momchil Velkov in

11297 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11298 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11333 * Makefile.maint: Sync with Bison, i.e.:
11334 (po-check): Scan .l and .y files instead of the
11335 .c and the .h files that they generate. This fixes the bug
11336 reported by Tim Van Holder in:
11337 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11338 Look for N_ as well as for _. Try to avoid matching #define for

11355 than assigning in main, to avoid HP cc +O3 optimizing it away.
11357 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11359 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11360 option. Process --recheck after parsing all options. Pass -q

11397 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11399 We _have_ to stop using the old compatibility scheme that tried to
11400 avoid useless backslashes because Libtool 1.4.3 contains a
11401 AC_DEFINE([error_t], [int],
11402 [Define to a type to use for \`error_t' if it is not
11403 otherwise available.])
11404 We _have_ to quote the single quote and backslashes with \. The
11405 old compatibility scheme saw that ` was backslashed, and therefore
11406 did not quote the single quote. Hence before this patch, Autoconf
11407 was not compatible with Libtool.

11798 Reported by Alexandre Duret-Lutz.
11800 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11861 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11862 aclocal invocation, as Gettext macros might not be visible to

11865 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.

11898 * tests/torture.at (Configuring subdirectories): Be robust to

11900 the two last configure runs, using two different sets of
11901 arguments, trigger a legitimate error.
11903 2002-09-28 Akim Demaille <akim@epita.fr>
11905 * tests/m4sh.at (Functions Support, Functions and return Support):
11908 2002-09-28 Akim Demaille <akim@epita.fr>
11910 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11911 autoheader are Perl programs.

11940 (autoscan.list): New target --this file is no longer a source.
11941 (autoscan.pre): New file.
11943 2002-09-28 Akim Demaille <akim@epita.fr>
11945 * bin/autoscan.in (@kinds): Make them singular.
11947 (&init_tables): When --debug, report the list of rules to ease
11948 tracking changes in autoscan.list.
11949 * lib/autoscan/autoscan.list (function): Strip comments, sort.

11961 * lib/autoscan/functions, lib/autoscan/headers,
11962 * lib/autoscan/identifiers, lib/autoscan/makevars,
11963 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11964 `functions' line is now prefixed with `function:'.
11965 * bin/autoscan.in (&init_tables): Adjust.
11967 2002-09-28 Akim Demaille <akim@epita.fr>
11969 From now on, autoscan files must always map a macro name to a
11970 word: there is no `default' macro for autoscan.
11972 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11974 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11977 2002-09-28 Akim Demaille <akim@epita.fr>
11979 * bin/autoscan.in (%c_keywords): Remove.
11980 (&used): Keep only track of the words we might be interested in.

11995 Thanks to Bill Moseley and Paul Eggert.
11996 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11997 the tmpdir must be created.
11998 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11999 dir be in the build tree, instead of $TMPDIR.

12003 * bin/autoscan.in: Improve the comments.

12013 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12015 2002-09-26 Akim Demaille <akim@epita.fr>
12017 Single suffix rules and seperated dependencies are not portable.
12019 * doc/autoconf.texi (Installation Directory Variables): Update.
12020 (Limitations of Make): Some about `Single Suffix Rules and
12021 Separated Dependencies'.
12022 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)

12025 2002-09-25 Paul Eggert <eggert@twinsun.com>
12027 * BUGS (Interoperability bugs): New section. Mention libtool
12028 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12030 2002-09-24 Paul Eggert <eggert@twinsun.com>
12032 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12033 make handles suffix-rules differently from GNU make.
12035 * bin/Makefile.am (SUFFIXES, .in): Remove.
12036 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12037 Move the body of the old .in rule here.
12039 2002-09-16 Akim Demaille <akim@epita.fr>
12041 i960 compilers create `b.out' files by default.
12042 Reported by Ralf Corsepius.
12044 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12045 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12047 2002-09-13 Paul Eggert <eggert@twinsun.com>
12049 * doc/autoconf.texi (Particular Headers): Remove obsolete
12050 reference to `struct timezone' in the description of

12061 2002-09-13 Akim Demaille <akim@epita.fr>
12063 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12064 reading config.log when the compiler is rejected.
12065 Suggested by Guido Draheim.
12067 2002-09-13 Akim Demaille <akim@epita.fr>
12069 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12070 (chdir_init) might hang when stat'ing mounted directories.
12071 Reported by Vance Shipley.
12073 2002-09-12 Akim Demaille <akim@epita.fr>
12075 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12078 2002-09-12 Akim Demaille <akim@epita.fr>
12080 * doc/autoconf.texi (Defining Symbols): Present two different
12081 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12082 difference between 1 argument calls, and 2-3 argument calls.
12084 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12086 * doc/autoconf.texi: Review grammar and punctuation.
12088 2002-09-11 Paul Eggert <eggert@twinsun.com>
12090 * doc/autoconf.texi: Fix minor formatting, spelling, and
12092 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12093 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12096 2002-09-11 Akim Demaille <akim@epita.fr>
12098 * doc/autoconf.texi (Questions): Rename as...
12100 (Defining Directories): New.
12102 2002-09-09 Akim Demaille <akim@epita.fr>
12104 * doc/autoconf.texi (Making testsuite Scripts): Update.
12105 Suggested by Nishio Futoshi.
12107 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12109 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12110 plain `@' is wanted.
12112 2002-09-09 Akim Demaille <akim@epita.fr>
12114 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12115 `duplicates', since the algorithm was too naive and could keep
12116 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12117 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12118 Reported by Ralf Corsepius.
12119 * tests/torture.at (Configuring subdirectories): Exercise these
12122 2002-09-09 Akim Demaille <akim@epita.fr>
12124 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12125 looking for a replacement file.
12126 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12127 directory is relative.
12128 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12129 directory definition.
12130 Reported by Andreas Schwab and Jim Meyering.
12132 2002-09-06 Akim Demaille <akim@epita.fr>
12134 * doc/autoconf.texi (Setting Output Variables): Clarify what
12135 precious variables are.
12136 Suggested by Pontus Skoeld.
12138 2002-09-05 Akim Demaille <akim@epita.fr>
12140 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12141 (ifnames, autoscan, autom4te): Since we don't only depend on
12142 configure.ac variables (such as VERSION etc.), but also on prefix
12143 and so forth, depend on Makefile, not configure.ac.
12144 Reported by Alexandre Duret-Lutz.
12145 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12147 2002-09-05 Kevin Ryde <user42@zip.com.au>
12149 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12150 doesn't seem to be confined to ia64, just say "some versions".
12152 2002-09-04 Akim Demaille <akim@epita.fr>
12154 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12156 * Makefile.am (maintainer-clean-local): Remove.
12157 (MAINTAINERCLEANFILES): Remove COPYING.
12159 2002-09-03 Paul Eggert <eggert@twinsun.com>
12161 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12162 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12165 2002-09-03 Akim Demaille <akim@epita.fr>
12167 * configure.ac: Bump to 2.53d.
12168 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12169 as of today, on Automake's team suggestion.
12171 2002-09-03 Akim Demaille <akim@epita.fr>
12175 2002-09-02 Akim Demaille <akim@epita.fr>
12177 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12179 * configure.ac: Disable SITE_MACRO_DIR.
12181 2002-09-02 Jim Meyering <meyering@lucent.com>
12183 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12184 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12185 Also, tweak grammar: s/make sure to/be sure to/.
12187 2002-09-02 Paul Eggert <eggert@twinsun.com>
12189 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12190 directory names are generally preferable to physical names.
12192 2002-09-02 Akim Demaille <akim@epita.fr>
12194 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12195 Reported by Raja R. Harinath.
12196 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12197 * bin/autoupdate.in: Use error instead of die.
12199 2002-09-01 Paul Eggert <eggert@twinsun.com>
12201 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12202 ordinary shell concatenation rather than echo+tr+sed command that
12203 runs afoul of a long-line-related sed bug in Solaris 8.
12205 * bin/autoheader.in (parse_args): --warning -> --warnings.
12207 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12208 stdout, as traditional "ls" does.
12209 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12210 _AC_COMPILER_EXEEXT_O): Likewise.
12211 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12213 * bin/autoconf.as: Add --prepend-include option. This patch was
12214 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12215 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12217 * bin/autoconf.in, configure: Regenerate.
12219 * doc/autoconf.texi (Special Shell Variables): Mention
12220 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12222 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12223 MAILPATH and set PS1, PS2, PS4 to default values, to work
12224 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12225 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12226 the Autoconf documentation specifies; fall back to "unset" only if
12227 this fails. Use a shell for-loop for this rather than an m4 loop,
12228 to shorten the output script.
12230 2002-08-30 Paul Eggert <eggert@twinsun.com>
12232 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12233 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12234 for the CDPATH problem. Document PWD.
12235 (Limitations of Builtins): Document the problem that "cd $foo" and
12236 "ls $foo" may refer to different directories in shells conforming
12237 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12238 example, since the old example is now out of date.
12240 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12241 FOO" and "ls FOO" talk about different directories; this catches
12242 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12245 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12246 of rolling our own unset.
12247 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12248 in practice we needn't worry about CDPATH if unset doesn't work.
12250 * Makefile.in, aclocal.m4, bin/Makefile.in,
12251 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12252 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12253 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12254 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12255 tests/Makefile.in: Regenerate with Automake 1.6.3.
12257 * config/config.guess, config/config.sub, config/mkinstalldirs:
12260 * configure: Regenerate with self.
12262 2002-08-30 Kevin Ryde <user42@zip.com.au>
12264 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12267 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12269 * bin/autom4te.in (Request::load): Correctly test for "do" read
12272 2002-08-29 Akim Demaille <akim@epita.fr>
12274 * lib/Autom4te/General.pm (&xqx): New.
12275 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12276 hand, which is not portable.
12278 * bin/autom4te.in: Use them.
12279 Use &error instead of die.
12280 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12283 2002-08-17 Paul Eggert <eggert@twinsun.com>
12285 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12286 default list of compilers to try, since it was long ago superseded
12287 by the ksh fc builtin. Suggested by Steven G. Johnson.
12289 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12291 * doc/autoconf.texi (Invoking autom4te): End the option table,
12292 fixing a bug introduced by the previous patch.
12293 (Limitations of Make): Add a 'target lookup' subentry in the
12294 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12296 2002-07-29 Mark D. Roth <roth@feep.net>
12298 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12299 options and use $AUTOM4TE_PATH.
12300 * doc/autoconf.texi: Remove documentation of autom4te
12301 --include-envvar and --site-macro-subdir options and document
12302 use of $AUTOM4TE_PATH.
12303 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12304 arguments from each language section.
12306 2002-07-29 Paul Eggert <eggert@twinsun.com>
12308 * doc/install.texi: Include copyright symbol in copyright notice.
12310 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12312 (AM_MAKEINFOFLAGS): New macro.
12313 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12314 * Makefile.am (INSTALL): Use the new macros.
12315 Use -o rather than --output, since "missing" does not grok --output.
12317 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12319 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12320 comments do not always work. Never trust the exit status of
12323 2002-07-24 Kevin Ryde <user42@zip.com.au>
12325 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12326 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12328 2002-07-23 Paul Eggert <eggert@twinsun.com>
12330 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12331 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12332 apparently treats PATH="nonexistent" as if it contained ".".
12333 Bug reported by Stefan `Sec' Zehl.
12335 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12337 * doc/autoconf.texi (Limitations of Make): Mention the special
12338 handling of the obj/ directory by BSD make.
12340 2002-07-20 Kevin Ryde <user42@zip.com.au>
12342 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

12371 2002-07-18 Akim Demaille <akim@epita.fr>,
12372 Alexandre Duret-Lutz <duret_g@epita.fr>
12374 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
12375 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
12377 2002-07-17 Russ Allbery <rra@stanford.edu>

12380 description of the tarname default.
12382 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12384 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12385 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12386 latter was not run.
12388 2002-07-17 Akim Demaille <akim@epita.fr>
12390 * lib/Autom4te/General.pm (find_file): Browse the directories in
12391 the order they are given.

12603 This improves on an earlier suggestion by H. Peter Anvin.
12605 2002-05-16 Paul Eggert <eggert@twinsun.com>
12607 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12608 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12609 Both macros now accept an optional source-dir arg.
12610 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12612 * NEWS: Document this.
12613 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12615 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12616 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12617 not for GNU extensions; this undoes part of the 2000-11-03 change,
12618 reverting to 2.13-compatible behavior.

12626 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12627 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12628 and it causes a 'test' syntax error if it fails.
12629 Bug reported by Stephen Gildea.
12631 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12632 If prototypes are supported, use them to check this at compile-time,
12633 instead of trying to check it at run-time. If we must do a run-time
12634 check, assume that setvbuf is standard when cross-compiling, as
12635 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12636 Bug reported by Paul D. Smith.
12638 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12639 argument specifying location of getloadavg.c. This removes a
12640 FIXME. This idea was taken from Jim Meyering's implementation in
12642 * doc/autoconf.texi (Particular Functions): Document this.
12643 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12644 that's what the code does; this fixes a bug reported by
12647 2002-05-03 Akim Demaille <akim@epita.fr>
12649 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12650 autopoint instead of gettextize.
12651 ($uses_alocal): Rename as...
12652 ($uses_aclocal): this.
12653 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12654 Suggested by Bruno Haible.
12656 2002-05-03 Akim Demaille <akim@epita.fr>
12658 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12660 2002-04-29 Paul Eggert <eggert@twinsun.com>
12662 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12663 files to be 1 second older; just set them to be the same time.
12664 Also, sleep 1 second after the first aclocal, to work around
12665 problems with sub-second time stamps on the input files.
12667 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12669 * doc/autoconf.texi: Mention "set -e -x" lossage
12670 under node "Limitations of Builtins".

12676 From Christian Cornelssen.
12678 2002-04-29 Akim Demaille <akim@epita.fr>
12680 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12681 of lack of $LINENO support, then the test will compare the $LINENO
12682 in testsuite vs. the lineno in the test file. This is wrong, of
12684 Be sure to protect it.
12685 Reported by Patrick Welche.
12687 2002-04-25 Akim Demaille <akim@epita.fr>
12689 * doc/autoconf.texi (Obsolete Macros): Typo.
12690 Reported by Vladimir Volovich.
12692 2002-04-25 Akim Demaille <akim@epita.fr>
12694 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12695 than some of the input files, hence, on the second run of aclocal,
12696 if some of its input are younger, make them older.
12697 Suggested by Paul Eggert.
12699 2002-04-25 Akim Demaille <akim@epita.fr>
12701 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12707 and ac_subst_vars be sh variables containing the list of
12708 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12710 (_AC_INIT_PREPARE): Use them to log them.
12711 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12712 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12713 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12714 _AC_SUBST_FILES and _AC_SUBST_VARS.
12715 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12717 2002-04-24 Akim Demaille <akim@epita.fr>
12719 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12720 autoheader, so that automake does not complain about a missing
12721 config.h.in that was to be created.
12723 2002-04-23 Akim Demaille <akim@epita.fr>

12874 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12875 contains no literal separators.
12877 2002-04-03 Akim Demaille <akim@epita.fr>
12879 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12880 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12881 Use dnl, not the KILL diversion.
12883 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12884 (AC_CONFIG_LINKS): here.
12886 Don't use the KILL diversion, as it kills spurious output, which
12887 results in failures being hidden.
12888 Use m4_defn where appropriate.
12889 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12890 after the second argument.
12892 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12893 syntax, as it is provided by M4sugar.
12894 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12896 2002-04-03 Andreas Schwab <schwab@suse.de>

12910 (_AC_COMPILER_OBJEXT): Use them.
12911 Fixes Debian #138666.
12913 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12915 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12917 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12918 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12919 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

12921 (AC_C_CONST): Same.

12935 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12936 to avoid versions of HP C which don't allow that.
12938 2002-03-27 Paul Eggert <eggert@twinsun.com>
12940 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12941 (AS_SHELL_SANITIZE): Invoke it.

12952 2002-03-25 Paul Eggert <eggert@twinsun.com>
12954 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12955 as POSIX requires, as it doesn't work with Zsh.
12956 * doc/autoconf.texi (Assignments): Document the problem.
12958 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12960 * doc/autoconf.texi (Limitations of Make): Mention more issue
12961 about VPATH, overriding of macros in sub-makes, and handling of
12964 2002-03-21 Paul Eggert <eggert@twinsun.com>
12966 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12967 problem with here-document buffer boundaries.
12969 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12970 when reinvoking the shell, to work around problems with installers
12971 who put strange things like "cd" commands in their environments.

12991 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

12996 (Limitations of Usual Tools): Add mkdir section.
12998 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12999 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13000 back on AS_DIRNAME to compute prefixes otherwise; this is
13001 roughly what mkinstalldirs does. That way, we need not have
13002 our own filename disassembler. The old disassembler did not
13003 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13005 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13006 Create at_test_all by a series of assignments,
13007 not by a single assignment of a long string. The latter causes ksh
13008 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13009 presumably because of a buffer overrun.
13011 2002-03-14 Paul Eggert <eggert@twinsun.com>
13013 * lib/autotest/general.m4 (at_times_skip):
13014 Renamed from at_times. Now a boolean.
13015 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13016 says 'times: not found'.

13020 * bin/autoreconf.in (&study_gettextize): New.
13021 (&autoreconf): Handle newest gettextize.

13032 Add information about stdint.h and inttypes.h from Paul Eggert.

13045 2002-03-11 Andreas Schwab <schwab@suse.de>

13048 does not do it if --with-lispdir is given.

13057 subdirectory should exist.
13059 2002-03-08 Akim Demaille <akim@epita.fr>
13061 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13063 2002-03-08 Akim Demaille <akim@epita.fr>
13065 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13066 aliases the actual variables, and modifications of the former
13069 2002-03-08 Akim Demaille <akim@epita.fr>
13071 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13072 because of C-c: have m4 output in tmp files, then mv them.

13095 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13096 * lib/autoconf/general.m4 (AC_INIT): More informative error
13097 message for LIBOBJ.
13099 2002-03-04 Akim Demaille <akim@epita.fr>

13104 2002-03-04 Akim Demaille <akim@epita.fr>
13106 * doc/autoconf.texi (Transforming Names): Equality between target
13107 and host is irrelevant.
13108 (Specifying Names, Canonicalizing): Remove all references to the
13109 backward compatibility hooks. Rather, collect them all into...
13110 (Hosts and Cross-Compilation): this new section.
13111 * doc/install.texi (System Type): Ditto.
13112 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13113 that `--host' implies cross-compilation.
13115 2002-03-04 Akim Demaille <akim@epita.fr>
13117 * doc/autoconf.texi (Evaluation Macros): New.
13118 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13120 (_m4_foreach): Define the variant with immediate evaluation so
13121 that it contains exactly the items, not an expression which
13122 evaluation is the current item.
13123 (m4_re_string, m4_re_word): Don't over quote them.
13125 2002-03-04 Akim Demaille <akim@epita.fr>
13127 Instead of having stacking `shift's evaluated at the end, let
13128 `foreach' loops immediately evaluate them.
13130 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13131 $*. This is the n-th time I change my mind, but hopefully this is
13134 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13136 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13137 it was only a hack for m4_text_wrap.
13138 (m4_car2): Remove, replaced by...
13140 (_m4_foreach): Adjust.
13141 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13142 m4_bpatsubst for clarification.

13196 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13233 2002-02-05 Akim Demaille <akim@epita.fr>
13235 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13258 optional are the sum of the previous files on the command line'.
13259 Also, pass `--reload-state=' on them, so...
13260 (handle_m4): don't.

13262 (M4sh): Rely on M4sugar.

13295 2002-01-28 Akim Demaille <akim@epita.fr>
13297 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13300 2002-01-28 Akim Demaille <akim@epita.fr>
13302 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13303 AUTOTEST_PATH *after* it was set.
13304 Don't put `.' in the PATH: the user should be precise and `./' if
13305 needed. In addition, given that the test suite does some `cd', if
13306 `.' is in the path, the `tested programs' sections will report
13307 programs found in the test suite's directory, while during the
13308 tests (performed in their own directory), these programs are no
13309 longer visible. In other words, the results is confusing and

13387 and PACKAGE_BUGREPORT from here...
13388 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13390 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13391 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13392 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13393 * tests/tools.at (autoheader): Adjust.
13394 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13396 2002-01-06 Akim Demaille <akim@epita.fr>
13398 * bin/autoscan.in (scan_file): Use `&used'.
13400 2002-01-03 Akim Demaille <akim@epita.fr>
13402 * doc/autoconf.texi (Output): Improved wording regarding use of
13406 2001-12-18 Kevin Ryde <user42@zip.com.au>
13408 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13409 sometimes needing writable input.
13411 2001-12-17 Jim Meyering <meyering@lucent.com>
13413 * doc/autoconf.texi (New Macros): Tweak wording.
13415 2001-12-14 Akim Demaille <akim@epita.fr>
13417 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13418 trailing files, don't apply `-rf' to files which might not be
13419 created by configure (core, core.*, and *.core), but just `rm -f'.
13420 Suggested by Jonathan Kamens.
13422 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13424 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13426 2001-12-14 Akim Demaille <akim@epita.fr>
13428 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13430 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13432 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13433 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13434 abs_srcdir, top_srcpath to abs_top_srcdir.
13435 (_AC_OUTPUT_FILES): Adjust.
13436 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13437 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13438 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13440 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13442 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13443 C/Fortran linking on HP/UX, by extracting the Fortran library
13444 search path from the LPATH line in the $F77 -v output.
13446 2001-12-12 Kevin Ryde <user42@zip.com.au>
13448 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13449 forbidden file descriptors table.
13451 2001-11-26 Akim Demaille <akim@epita.fr>
13453 * bin/autoscan.in (%c_keywords): Build it at top level.
13454 Map to 1 in order to simplify its uses.
13456 2001-11-26 Akim Demaille <akim@epita.fr>
13458 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13459 Remove $filepath, useless.
13460 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13461 variables, they are really part of the tokens.
13462 Split the input line on spaces and then look for tokens.
13463 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13464 because of `lex$U.$(OBJEXT)'.
13465 (&scan_files): Use "@list" instead of join.
13466 * doc/Makefile.am (CLEANFILES): Add *.fns.
13468 2001-11-26 Akim Demaille <akim@epita.fr>
13470 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13471 Remove, replaced by...
13472 * tests/wrappl.in: Be common for all the Perl executables.
13473 In particular autoscan and autoheader want -I.
13474 * configure.ac: Adjust.
13475 * lib/autoscan/headers: errno.h is portable.
13477 2001-11-26 Akim Demaille <akim@epita.fr>
13479 * bin/autoscan.in (used): New.
13482 2001-11-26 Akim Demaille <akim@epita.fr>
13484 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13486 (&scan_sh_file): Remove a duplicate pattern.
13487 (&check_configure_ac): Use long options.
13488 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13490 2001-11-26 Akim Demaille <akim@epita.fr>
13492 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13493 Before, having a line containing the opening of a multi line
13494 comment made the whole line be ignored.
13496 2001-11-26 Akim Demaille <akim@epita.fr>
13498 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13499 (testsuite Scripts): Be one of its subsection.
13500 (Autotest Logs): New.
13502 2001-11-26 Akim Demaille <akim@epita.fr>
13504 Test groups are now run two directories deeper.
13506 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13507 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13509 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13510 top_srcdir, builddir and top_builddir.
13511 Use `at_*dir' relatively to the directory containing the
13512 suite, use `*dir' when relatively to the current group dir.
13514 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13516 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13517 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13518 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13521 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13523 * doc/autoconf.texi (Using System Type): Add an example of `case
13524 $host' usage so people quit using `case $target' everywhere.
13526 2001-11-22 Akim Demaille <akim@epita.fr>
13528 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13529 spotted by Jim Meyering.
13531 2001-11-16 Paul Eggert <eggert@twinsun.com>
13533 This patch implements a `long double' suggestion by Oliver Kiddle.
13535 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13536 static, to catch errors if the value isn't known at compile-time
13537 and the compiler supports dynamic arrays. Change its name from
13538 `_array_' to `test_array' to avoid potential name clashes.
13539 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13540 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13541 better than double. Catch a bug in GCC 2.95.2 x86.
13542 * doc/autoconf.texi (C Compiler): Document the above.
13545 2001-11-13 Akim Demaille <akim@epita.fr>
13547 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13549 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13551 2001-11-13 Akim Demaille <akim@epita.fr>
13553 * lib/autotest/general.m4 (AT_INIT): After having run the test
13554 group, go back to the initial directory, not to at_suite_dir.
13556 2001-11-13 Akim Demaille <akim@epita.fr>
13558 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13559 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13560 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13562 (AT_CHECK_CONFIGURE): Use absolute paths.
13563 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13564 The problem is still the old one: there is no means in M4 (that I
13565 know about) to create a defining macro, because there is no means
13566 to create `$1' etc., therefore, the defining macro ``swallows''
13567 all the arguments meant to the defined macro.
13569 2001-11-13 Akim Demaille <akim@epita.fr>
13571 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13572 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13574 * tests/aclocal.m4: Remove, as it is no longer used.
13576 2001-11-13 Akim Demaille <akim@epita.fr>
13578 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13579 variable names when referring to a single test group, or to
13580 `suite' when referring to the whole test suite.
13581 `at_last_test' is removed: m4 compute at_format itself.
13582 (at_stdout, at_stder1, at_stderr): New variables.
13583 (AT_CHECK): Use them.
13585 2001-11-13 Akim Demaille <akim@epita.fr>
13587 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13589 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13590 Do it as soon as a test fails, don't wait till the end of the test
13592 Don't remove $as_me.[0-9]*, since these files no longer exist.
13594 2001-11-13 Akim Demaille <akim@epita.fr>
13596 * tests/tools.at: Use absolute paths, since we are no longer run
13599 2001-11-13 Akim Demaille <akim@epita.fr>
13601 Now that tests are running in their own private dir, there is no
13602 need to list the files to remove at the end of tests groups.
13604 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13605 (AT_data_files, at_data_files): Remove.
13606 (AT_CLEANUP, AT_DATA): Simplify.
13608 Remove the group dir if !debug && !failed.
13609 * tests/atspecific.m4: Adjust.
13611 2001-11-13 Akim Demaille <akim@epita.fr>
13613 Start a new layout for Autotest: `testsuite' creates
13614 `testsuite.dir' in which the at-check-line etc. files are to be
13615 found, and `testsuite.dir/003' where the test group 3 is run.
13617 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13618 at_check_line_file, at_format, at_test_normalized, at_group_dir
13620 Create the directories.
13621 Use absolute paths for at- files.
13622 (AT_CHECK): Adjust.
13624 2001-11-11 Michael Matz <matz@kde.org>
13626 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13628 (m4_car): Properly quote arguments.
13630 2001-11-13 Akim Demaille <akim@epita.fr>
13632 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13633 with stricter rules on LIBOBJS.
13635 2001-11-12 Paul Eggert <eggert@twinsun.com>
13637 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13638 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13641 2001-11-12 Akim Demaille <akim@epita.fr>
13643 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13645 2001-11-12 Akim Demaille <akim@epita.fr>
13647 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13648 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13649 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13650 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13651 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13652 specify to what the macro should be defined (typically to 1).
13654 2001-11-12 Akim Demaille <akim@epita.fr>
13656 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13659 2001-11-12 Akim Demaille <akim@epita.fr>
13661 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13662 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13663 definition used by Automake where LEX is +/- "${missing} lex" and
13664 `missing' itself contains variables.
13666 2001-11-12 Akim Demaille <akim@epita.fr>
13668 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13669 Now that M4sh pushes BODY, the comments were output at the end of
13672 2001-11-08 Akim Demaille <akim@epita.fr>
13674 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13675 that we can trace macros from aclocal.m4.
13676 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13677 obsoleted, and redirect to the former anyway.
13678 Reported by Ralf Corsepius.
13680 2001-11-08 Akim Demaille <akim@epita.fr>
13682 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13683 processed only if present.
13684 * tests/torture.at (Configuring subdirectories): Use autoreconf
13685 instead of successive calls to autoconf.
13686 Add a nonexistent subdirectory to exercise the patch above.
13687 Reported by Ralf Corsepius.
13689 2001-11-08 Kevin Ryde <user42@zip.com.au>
13691 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13692 doesn't accept .S files.
13694 2001-11-07 Akim Demaille <akim@epita.fr>
13696 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13697 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13698 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13699 * bin/autom4te.in (warn_forbidden): New.
13700 (handle_output): Use it.
13701 Read m4_pattern_forbid with messages.
13703 2001-11-05 Akim Demaille <akim@epita.fr>
13705 * bin/autom4te.in (--normalize): Remove.
13706 * lib/autom4te.in: Adjust.
13708 2001-11-05 Akim Demaille <akim@epita.fr>
13710 * tests/Makefile.am (testsuite): Rename this target as...
13711 ($(TESTSUITE)): this.
13714 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13716 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13717 the --prefix option, also remove it's argument.
13719 2001-11-05 Akim Demaille <akim@epita.fr>
13721 * doc/autoconf.texi (testsuite Invocation): Update.
13722 (Writing testsuite.at): Update.
13724 2001-11-03 Akim Demaille <akim@epita.fr>
13726 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13728 2001-11-03 Akim Demaille <akim@epita.fr>
13730 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13731 (&file_name_is_absolute): New, wrappers around routines from
13733 Use and export them.
13734 (&find_configure_ac): Optionally take a directory where to look at.
13735 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13737 Default @ARGV to `.', not find_configure_ac.
13738 (&autoreconf): Argument is a directory.
13739 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13740 * doc/autoconf.texi (autoreconf Invocation): Update.
13742 2001-11-03 Akim Demaille <akim@epita.fr>
13744 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13745 (@export_forward_subs): New.
13746 Add basename, dirname, and fileparse.
13748 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13749 Don't look for aclocal flags if we already know aclocal is not
13751 Move aclocal.m4t only if it exists.
13752 Reported by Ezra Peisach.
13754 2001-11-03 Akim Demaille <akim@epita.fr>
13756 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13757 passed on command line, defaulting to ./configure.ac if present.
13758 (&maybe_autoreconf, File::Find): Remove, unused.
13759 (&autoreconf): If autoconf is not used, don't try to trace.
13761 2001-11-02 Akim Demaille <akim@epita.fr>
13763 * configure.ac: Bump to 2.52g.
13765 2001-11-02 Akim Demaille <akim@epita.fr>
13769 2001-11-02 Akim Demaille <akim@epita.fr>
13771 * config/config.guess, config/config.sub, doc/standards.texi:
13772 * config/lispdir.m4: Update from masters.
13773 * configure.ac: Bump to 2.52f.
13775 2001-11-02 Akim Demaille <akim@epita.fr>
13777 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13778 Don't run aclocal when aclocal.m4 is not from aclocal.
13780 Don't run libtoolize and gettextize if --install is not given.
13782 2001-11-01 Paul Eggert <eggert@twinsun.com>
13784 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13785 be invoked before _AS_LINENO_PREPARE.
13786 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13787 than character ranges.
13789 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13790 invoking AS_BASENAME. Set the locale variables to 'C' if
13791 possible, as POSIX requires this to get the traditional
13793 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13795 2001-10-31 Paul Eggert <eggert@twinsun.com>
13797 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13798 with {}, as that triggers a bug in Bash 2.05.
13800 (_AS_LINENO_PREPARE): Use Sed rather than
13801 Awk. Fix the sed prepass to work even if there are multiple
13802 instances of $LINENO on the same line. Do not substitute for
13803 other variables like $LINENOT. Do not check file dates; such a
13804 check is unreliable on sufficiently fast machines, and removing
13805 the check makes the code simpler and more reliable. Check for
13806 output and chmod failures.
13808 * doc/autoconf.texi (Special Shell Variables): Document
13811 2001-10-31 Akim Demaille <akim@epita.fr>
13813 * tests/Makefile.am (atconfig): Remove this target, Automake
13816 2001-10-31 Akim Demaille <akim@epita.fr>
13818 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13819 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13820 provided, while it is optional.
13821 * configure.ac: Adjust.
13823 2001-10-26 Paul Eggert <eggert@twinsun.com>
13825 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13826 lib/Autom4te/Struct.pm:
13827 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13830 * doc/autoconf.texi (Special Shell Variables): Document some
13831 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13833 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13834 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13835 eval $LINENO is not portable in practice.
13837 2001-10-24 Akim Demaille <akim@epita.fr>
13839 * lib/Autom4te/General.pm (backname): New.
13841 2001-10-24 Akim Demaille <akim@epita.fr>
13843 * m4/: Remove, merged into...
13846 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13848 * doc/autoconf.texi (Shellology): Mention the problems with bash
13849 2.05's use of ANSI quoting in its `set' builtin.
13851 2001-10-22 Paul Eggert <eggert@twinsun.com>
13853 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13854 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13855 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13856 POSIX decided to standardize on the int flavor of strerror_r.
13857 Always do char* test, as there's no reason not to.
13858 Assign to a char* var, to catch strerror_r that returns int*.
13860 * doc/autoconf.texi (Particular Functions):
13861 Document the above changes. Also, document the fact that
13862 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13864 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13866 2001-10-20 Akim Demaille <akim@epita.fr>
13868 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13869 the executable was missing from the log.
13871 2001-10-20 Akim Demaille <akim@epita.fr>
13873 * lib/Autom4te/General.pm (&update_file): If destination is
13874 unchanged, remove the source.
13875 (&up_to_date_p): Don't be verbose, be debug.
13876 * bin/autoreconf.in: No longer support --m4dir.

14347 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14349 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14353 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14354 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14355 be used instead of ':'.
14356 * lib/autotest/general.m4: Replace occurrences of ':' in
14357 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14359 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14361 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14362 arguments. Fixed a typo.
14364 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14366 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14367 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14369 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14371 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14373 * bin/autoheader.in: Reworded a few comments.
14374 * bin/autoconf.in: Reworded help text for a few options.

14378 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14380 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14381 already have $file). Set output files to binary mode (helps avoid
14382 CR issues on DOSish systems).
14384 2001-09-19 Akim Demaille <akim@epita.fr>
14386 * lib/autotest/general.m4: Englishoes.
14387 From Tim Van Holder and Alexey Mahotkin.
14389 2001-09-18 Paul Eggert <eggert@twinsun.com>
14391 * doc/autoconf.texi (Common Shell Constructs): New node,
14392 documenting AS_DIRNAME.
14393 (Limitations of Usual Tools): Refer to it when discussing dirname.
14394 Also, update discussion of POSIX standard to reflect latest draft.
14396 * lib/autoconf/c.m4:
14397 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14399 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14400 Do not pass a first argument with leading '-'
14401 to expr, by parenthesizing initial integers that might be negative.
14403 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14404 now merely checks whether it is an error to pass an argument
14407 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14408 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14409 whether it is a (compile-time) error to pass an argument to
14410 getpgrp. This simpler test supports the revised documentation,
14411 and is all that AC_FUNC_GETPGRP's users really need.
14413 2001-09-18 Akim Demaille <akim@epita.fr>
14415 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14423 2001-09-18 Paul Wagland <paul@wagland.net>
14425 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14427 Add test for AS_BASENAME.
14428 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14429 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14430 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14431 * tests/base.at: Fixed the expected responses. The old ones were
14433 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14434 the documentation claims it should (and how it behaved in 2.13).
14436 2001-09-18 Akim Demaille <akim@epita.fr>
14438 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14439 the AC_CONFIG_COMMANDS invocation.
14440 This also solves the name clash problems.
14441 Don't set the package's ID.
14442 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14443 No longer to be shipped.
14444 (version.in): Remove.
14445 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14446 * lib/autoconf/status.m4: Adjust.
14447 Use `m4_PACKAGE_STRING'.
14448 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14449 the only optional argument is the name of the test suite.
14450 Expect `package.m4' to define the package signature.
14451 * lib/autom4te.in (Autotest): Add `package.m4?'.
14452 * tests/Makefile.am (package.m4): New.
14453 * tests/suite.at: ifnames is a victim.
14455 2001-09-18 Akim Demaille <akim@epita.fr>
14457 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14458 AC_LIBSOURCE, AC_CONFIG_FILES.
14459 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14460 program version string doesn't match the package's.
14461 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14464 2001-09-17 Paul Eggert <eggert@twinsun.com>
14466 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14467 Allow expression to return any value that can fit into unsigned long
14468 (not int, as before). Check for output errors.
14470 2001-09-17 Bruno Haible <haible@ilog.fr>
14472 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14473 Always include <stdio.h> and <stdlib.h>. Evaluate
14474 the expression in an extra function before these includes. Call
14475 fprintf "%d" only after ensuring the argument is of type 'int'.
14476 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14478 2001-09-17 Paul Eggert <eggert@twinsun.com>
14480 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14481 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14482 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14483 when they don't exist.
14485 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14486 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14489 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14490 version with the version used by fileutils 4.1, except use
14491 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14494 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14496 2001-09-13 Akim Demaille <akim@epita.fr>

14536 * lib/autotest/general.m4 (AT_INIT): Create and remove
14537 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14538 test suites can cohabit.
14540 2001-09-13 Akim Demaille <akim@epita.fr>
14542 * tests/mktests.sh: Don't output banners for empty test files.

14650 Be ready to handle filenames as stupid as `dnl.at', for if even
14651 the maintainer is dumb enough to do that...
14653 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14654 excellence in M4 quotation: consider `__file__' is active.
14656 And BTW, when invoking m4, pass the --include in the right order:

14816 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14817 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14819 Use -e, not -f, since /dev/null for instance is OK.
14820 (&parse_args): Adjust.
14821 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

14831 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

14833 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14834 find the executables for it.

14836 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14838 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14839 indeed related to running the test suite, while passing
14840 --autoconf-dir and others is related to running non installed
14841 Autoconf executables. So don't do that, leave it to...
14842 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14843 * tests/autoscan: New.
14844 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14863 2001-08-29 Akim Demaille <akim@epita.fr>

15330 autom4te.cache (it's a directory, not a file.
15331 * Makefile.am: Ditto (but maintainer-clean-local).
15333 2001-08-15 Akim Demaille <akim@epita.fr>
15335 * bin/autom4te.in (@m4_warning): New.
15336 (&handle_m4): Use it.
15337 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

15407 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15409 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15410 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15411 * doc/autoconf.texi (C Compiler Characteristics): Update

15414 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15416 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15417 magic values from an object file when cross-compiling.
15418 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15420 2001-08-10 Akim Demaille <akim@epita.fr>
15422 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15424 Suggested by Russ Allbery.
15426 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15428 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15429 current $prefix to the sub-configures.
15431 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15433 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15434 extension (needed on BeOS). Reported by Guido van Rossum.
15436 2001-08-09 Akim Demaille <akim@epita.fr>
15438 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15440 2001-08-07 Akim Demaille <akim@epita.fr>
15442 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15444 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15445 No need to remove the files before and after the each test, before
15446 each test and at the end of the suite is enough.
15447 Display only the children `times', not the shell's.
15448 If the test failed or was skipped, at-times is not available.
15450 2001-08-07 Akim Demaille <akim@epita.fr>
15452 Always produce testsuite.log, including when there are no
15453 failures. This helps getting information on skipped tests, and
15454 duration of the tests. Err, implement the latter btw.
15456 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15457 Dump information on the first run of each test.
15458 (AT_CLEANUP): Create `at-times' containing the duration of the
15461 2001-08-07 Akim Demaille <akim@epita.fr>
15463 The use of `dumpstat' revealed that `len' was used although it
15464 should not. m4_text_wrap was using it, but in the Autoconf world
15465 where it is legal. Hence (i) test M4sh in its own world, not
15466 Autoconf's, and (ii), ahem, fix the bug :)
15468 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15469 does not like `' instead of [].
15470 (AT_INIT): Forbid `^_?AT_'.
15471 And don't output such tokens.
15472 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15473 `script.as', and `autom4te.cache'.
15474 Remove `empty' and `macro' which are no longer used.
15475 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15476 * tests/m4sugar.at: Use it.
15477 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15479 2001-08-07 Akim Demaille <akim@epita.fr>
15481 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15483 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15485 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15487 2001-08-04 Akim Demaille <akim@epita.fr>
15489 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15490 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15492 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15493 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15494 (AC_F77_MAIN): Likewise.
15496 2001-08-04 Akim Demaille <akim@epita.fr>
15498 Don't rely on M4sugar outputting the patterns in files, since we
15499 might process the output _without_ running m4, hence without these
15502 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15503 * bin/autom4te.in (@Request::includes): Remove, unused.
15504 (@Request::source): Rename as...
15505 (@Request::input): this.
15506 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15507 (&handle_output): Fetch the patterns from the traces.
15508 `$forbidden' and `$allowed' are constant: use m//o.
15509 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15510 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15512 2001-08-04 Akim Demaille <akim@epita.fr>
15514 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15515 autoconf', i.e., in addition to caching traces, cache the output.
15517 * bin/autom4te.in (Request::cache): Rename as...
15518 (Request::id): this.
15519 ($cache, $icache, $tcache, $ocache): New.
15520 (&handle_m4): Save M4 output in the cache instead of $tmp.
15521 (&handle_output): Adjust.
15522 (&up_to_date_p): Check that the output cache is up to date too.
15523 (top level): Run `&handle_m4' iff force or the cache is invalid.
15524 Run `&handle_output' if the output cache is more recent.
15526 2001-08-04 Akim Demaille <akim@epita.fr>
15528 * bin/autom4te.in ($force): New.
15529 (&parse_args, &print_usage): -f, --force is a new option.
15530 (&handle_output): CPP directives might have spaces after `#'.
15531 (&parse_args): The first file only can be frozen.
15533 2001-08-04 Akim Demaille <akim@epita.fr>
15535 Don't let autom4te compute the `include' traces several times:
15536 first check that the trace cache file is up to date, and then
15537 compare its timestamp with that of the output.
15539 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15540 the preamble. Don't require 5.005 as Autom4te::General does it,
15541 and better yet (use `use', not `require'!).
15542 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15543 Class::Struct as Autom4te::Struct.
15544 * lib/Autom4te/General.pm (File::stat): Use it.
15545 (&mtime): New, export it.
15546 * bin/autom4te.in: Use it.
15547 Declare `$req' is invalid if it is outdated.
15548 Don't declare it valid before saving it if something went wrong.
15550 2001-08-04 Akim Demaille <akim@epita.fr>
15552 Autom4te shall not encode Autoconf data, and preselecting traces
15553 must be proposed to the users.
15555 * bin/autom4te.in (@required_trace): Remove.
15557 (&parse_args, &print_usage): -p, --preselect is a new option.
15558 (&up_to_date_p): Adjust.
15559 * bin/autoconf.in: Preselect some Autoconf macros.
15561 2001-08-04 Akim Demaille <akim@epita.fr>
15563 * tests/tools.at (autoconf --trace: user macros): Check traces on
15564 macros invoked without arguments, and macros invoked with multiple

15572 2001-08-03 Akim Demaille <akim@epita.fr>
15574 * bin/autoconf.in ($@): Work around the usual sh bug.
15577 2001-08-03 Akim Demaille <akim@epita.fr>
15579 Clean up the handling of the M4 builtins tracing exception.
15581 * bin/autom4te.in (Request::request): Don't complete M4 builtins

15584 (@m4_builtin): this.
15585 (%m4_builtin_alternate_name): New.
15586 (&parse_args): Complete the trace requests with alternate names.
15587 (&handle_traces): Hence no longer do it here.
15588 (&trace_requests): Remove, unused.

15592 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15593 m4_if, and m4_wrap.
15595 2001-08-03 Akim Demaille <akim@epita.fr>
15597 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15598 (m4_divert_pop): Dump the whole diversion stack when a diversion
15600 * bin/autom4te.in (&handle_output): Remember of the first
15601 occurrence of a possibly undefined macro, not the last.
15602 Complain about the possibly undefined macros in the same order as
15603 the appear in the output.
15604 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15605 * tests/tools.at (autoconf: forbidden tokens, basic)
15606 (autoconf: forbidden tokens, exceptions): No longer sort
15607 autoconf's stderr, as it is now deterministic.
15608 Check that `dnl' is caught.
15610 2001-08-01 Akim Demaille <akim@epita.fr>
15612 * configure.ac: Bump to 2.52c.

15629 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
15630 `END', as `Autom4te::General::END' will be triggered.
15631 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15632 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
15633 system to run `mv', `rm', and `cmp'.
