1271 Cover more potentially problemtic file names. Use the new

1275 The test suite did not cover this bug because the code was not
1276 quoting properly the arguments of `rm -f' (which "fails" silently)
1277 as well as the arguments of `diff' (whose output was redirected to

1523 * tests/m4sh.at (LINENO): Quote $0.
1525 Fix testsuite program wrapper for whitespace in `pwd`.
1526 The problem here is that the usual mantra is that command
1527 variables can contain arguments, thus we cannot just escape
1528 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1529 $top_builddir/tests directory early in $PATH, so that the
1530 wrappers are found by their plain name.
1531 * tests/wrapper.as: Put $testdir early in $PATH.

1537 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1539 * tests/torture.at (datarootdir workaround): Adjust.
1540 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1542 Fix Autotest for whitespace in `pwd`.
1543 * lib/autotest/general.m4 (AT_INIT)
1544 <at_func_create_debugging_script, Driver Loop>:
1545 Quote $at_group_dir.
1546 * tests/autotest.at (whitespace in absolute testdir): New test.
1548 * lib/autom4te.in: Quote @datadir@.
1550 Proper file name escaping in Autoconf programs and Perl modules.
1551 This includes escaping of characters special to the shell
1552 as well as special to Perl, e.g., leading `<' or `>'.
1553 For example, when $file starts with `>', `open ">$file"'
1554 wrongly tries to append to a different file.
1555 * bin/autoconf.as: Fix quoting for autom4te options.
1556 * lib/Autom4te/General.pm (shell_quote): New function, taken
1557 from coreutils, written by Jim Meyering.
1559 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1561 * bin/autoreconf.in (parse_args): Likewise.

1563 * bin/autoupdate.in (main): Likewise.
1564 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1565 * bin/ifnames.in: Likewise, XFile usage fixes.
1566 * tests/tools.at (autom4te and whitespace in file names): Extend
1567 test. Test twice, with special characters allowed on w32, and the
1568 rest. Test leading and trailing whitespace, for `open_quote'.
1569 (autotools and whitespace in file names): New, analogous test.
1570 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1571 by Russ Allbery and Eric Blake.
1574 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1575 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1576 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1577 (update_file, contents): Use it.
1579 * Makefile.am (autom4te-update): Rewrite for git.
1581 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1583 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1585 Fix copyright years.
1586 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1587 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1589 2007-12-04 Eric Blake <ebb9@byu.net>
1591 Manually resync with gnulib, since 'make cvs-update' no longer works.
1592 * build-aux/config.guess: New upstream version.
1593 * build-aux/config.sub: Likewise.
1595 When using older automake, don't downgrade build-aux/texinfo.tex.
1596 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1597 * doc/Makefile.am (TEXINFO_TEX): Add.
1599 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1601 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1602 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1603 #undef as this runs afoul of our new way of creating config.h.
1604 Problem reported by Jim Meyering in
1605 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1607 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1609 Fix autom4te for unusual characters in input file names.
1610 * bin/autom4te.in (files_to_options): Quote active characters
1612 * tests/tools.at (autom4te and white space in file names):
1615 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1616 Document that Tru64 awk always splits $0.
1618 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1620 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1621 `#AT_STOP_...' line at the end of each test.
1623 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1625 * lib/autotest/general.m4 (AT_INIT): For awk line number
1626 extraction script, ensure `$at_group' has a defined value
1627 even for the empty set, and properly quote its usage inside
1630 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1632 * doc/autoconf.texi (Shell Functions): New chapter. Document
1633 IRIX sh $0 issue in functions, move content from ...
1634 (Portable Shell): ... here.
1635 (Shell Script Compiler): Note that shell functions are not
1636 totally unportable any more.
1638 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1639 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1641 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1642 extracting the line numbers of the last needed test.
1644 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1646 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1649 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1651 Fix IRIX testsuite debugging failures: $0 in functions.
1652 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1653 Do not use $0 inside a function, as IRIX sh will set that to the
1654 function name rather than the script invocation name.
1656 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1657 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1659 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1660 to extract test scripts.
1661 (AT_INIT): Extract and cache test script line numbers.
1663 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1665 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1666 subsequent fixups; the awk -> here-document conversion trashes
1667 performance too much with AIX sh.
1669 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1671 * tests/local.at: Do not test m4, perl with AT_TESTED.
1673 Diagnose and guard against write errors dealing with config.status.
1674 The general idea is this: all write failures from `configure'
1675 writing `config.status' are indicated by $ac_write_error, which
1676 is only checked at the end. This is safe because config.status
1677 code is not executed before the file is complete. Other write
1678 failures, be they inside config.status, or in sub shell/awk
1679 scripts spawned from configure or config.status, typically need
1680 earlier checking, as their results are used right afterwards.
1681 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1682 before writing config.status, check afterwards.
1683 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1684 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1685 Set `ac_write_error' for write failures to config.status. Barf
1686 upon write failures to temporary files.
1687 Adjust note about closing and reopening the here-document.
1688 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1689 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1690 reopening the here-document.
1691 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1692 Ensure `ac_write_error' does not escape into config.status.
1693 Also, add a couple of code paths not yet exercised in the test
1694 suite: a config file with input from stdin, and a config header
1696 Suggestion for catching write errors by Bruno Haible.
1698 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1700 Avoid error with Tru64 awk and testsuite lines with many words.
1701 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1702 reads the testsuite, set the field separator to an unusual value,
1703 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1704 even splits the input if $i, i>0, was never accessed in the script.
1706 Revert 2007-10-17 change.
1707 * TODO: Multiline args in config files and headers mean something
1708 different and are not fixed, see
1709 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1710 Report by Stepan Kasal.
1712 * doc/autoconf.texi (Generic Programs): Fix typo.
1714 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1716 AC_*_TOOL does not canonicalize the prefix
1717 * doc/autoconf.texi (Generic Programs): Do not say that
1718 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1720 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1722 Diagnose write errors in config.status instantiations.
1723 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1724 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1726 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1727 Extend test to also check for some write error failures, using...
1728 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1729 Report by Bruno Haible.
1732 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1734 (_AT_CHECK): Use less indentation, to save space.
1736 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1738 Add witness macro for @top_build_prefix@ substitution.
1739 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1740 (_AC_OUTPUT_FILE): Mention it here.
1742 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1743 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1745 * lib/autotest/general.m4 (at_func_test): Remove.
1746 (AT_INIT): Pre-extract test groups into separate files.
1747 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1748 Remove at-test-source files together with the $at_group_dir.
1749 * tests/autotest.at (Long test source lines): New test.
1751 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1753 Shell functions and variables may share a namespace.
1754 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1757 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1759 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1762 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1764 * lib/autoconf/status.m4: Fix a couple of comment typos.
1766 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1768 2007-11-13 Jim Meyering <meyering@redhat.com>
1770 Clean up the rule to create "expr".
1771 * tests/Makefile.am (expr): Don't redirect directly to target.
1772 Redirect just once, not for each echo statement.
1773 Use $@, not literal "expr".
1775 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1777 Don't worry about preprocessor when testing long long.
1778 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1779 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1780 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1781 These no longer check for preprocessor flaws.
1782 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1783 Do not check for preprocessor flaws.
1785 2007-11-13 Jim Meyering <meyering@redhat.com>
1787 Adapt dependencies, now that a version change doesn't modify configure.ac
1788 * GNUmakefile: Remove "make clean" kludge.
1789 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1791 Don't redirect directly to target.
1792 Use $@, not literal "version.m4".
1794 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1796 * doc/autoconf.texi (Making testsuite Scripts): Document
1797 ":;{" shorthand as in previous patch.
1799 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1801 * doc/autoconf.texi (Limitations of Builtins): Document problem
1802 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1804 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1805 Use ":;{" shorthand.
1806 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1808 2007-11-12 Jim Meyering <meyering@redhat.com>
1810 Add more non-srcdir build support.
1811 * GNUmakefile (dummy): Split a long line.
1812 Add -v option to autoreconf invocation.
1814 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1815 * GNUmakefile (dummy): Remove INSTALL.
1817 Remove racy commands to build scripts in bin/ and tests/.
1818 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1819 are guaranteed to be built, remove the rules that tried to build
1820 them. Before, with a parallel build, these rules could lead to
1821 two processes writing tests/wrapper.in concurrently.
1823 Build in man/ only *after* building in bin/ and tests/.
1824 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1825 in both bin/ and tests/.
1827 Accommodate non-srcdir build-from-checkout.
1828 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1829 Use git's --git-dir=$srcdir/.git option.
1830 Add quotes, in case tarball_version_file contains shell meta-characters.
1831 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1832 * configure.ac: Pass "." to git-version-gen.
1834 Avoid spurious test failures due to version skew.
1835 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1837 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1839 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1840 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1841 Remove conftest.dSYM directory.
1842 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1843 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1844 Remove `conftest.*' recursively.
1845 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1846 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1848 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1850 Report and analysis by Jeff Squyres and Peter O'Gorman.
1852 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1854 Fix typos in variable names.
1855 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1857 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1859 Document that $((expression)) is not portable.
1860 * doc/autoconf.texi (Shell Substitutions): Here.
1862 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1864 Ignore configure --help* errors due to LINENO-impaired shells.
1865 * tests/torture.at (Configuring subdirectories, Deep Package):
1866 In the --help* tests in read-only trees, make `.' temporarily
1867 writable again for the `stderr' file, and ignore errors due to
1868 the attempt to write configure.lineno.
1869 Report by Patrick Welche.
1871 2007-11-10 Jim Meyering <meyering@redhat.com>
1873 Generate package.m4 in build-dir, not srcdir.
1874 * tests/Makefile.am (package.m4): Adjust target.
1875 Don't redirect directly to $@.
1876 (CLEANFILES): Add package.m4.
1877 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1879 When running $(AUTOTEST), search "." before searching $(srcdir).
1881 Avoid a race condition that would make parallel "distclean" fail.
1882 * tests/Makefile.am (distclean-generic): Replace the default,
1883 automake-provided rule with an identical one, but with an additional
1884 dependency on distclean-local. Simply adding the dependency would
1885 cause automake not to emit the rule at all.
1886 * BUGS: Building with -jN works, now.
1888 Distribute git-version-gen.
1889 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1890 since GNUmakefile is distributed, and requires it for dist* rules.
1892 Remove two more generated files from version control.
1893 * INSTALL: Remove generated file.
1894 * lib/autoscan/autoscan.list: Remove generated file.
1896 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1898 * GNUmakefile (PATH): Remove stray apostrophes; they become
1899 part of PATH, which isn't wanted here.
1901 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1903 New config files output variable `top_build_prefix'.
1904 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1906 * doc/autoconf.texi (Preset Output Variables): Document it.
1908 Report by Bob Friesenhahn.
1910 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1911 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1912 function, to parametrize arithmetic with expr vs. the shell.
1913 Use it where possible.
1914 Suggestion by Benoit Sigoure.
1916 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1918 Adjust the documentation of autotest WRT atlocal.
1919 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1920 when using Automake, to write a rule to produce atlocal, since it's
1921 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1922 distributed, not atconfig.in.
1924 2007-11-04 Eric Blake <ebb9@byu.net>
1926 Update list information.
1927 * README: Mention new autoconf-commit list.
1928 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1930 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1932 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1934 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1936 * build-aux/.gitignore: Ignore mkinstalldirs.
1938 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1940 2007-11-03 Jim Meyering <meyering@redhat.com>
1942 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1943 * build-aux/git-version-gen: This syncs from coreutils.
1945 Adjust the build procedure so "make check" works reliably.
1946 * README-hacking: Include an extra step between "make" and
1947 "make check" to ensure that the latter passes.
1949 Use just-built tools, when possible.
1950 * GNUmakefile (PATH): Set and export here, ...
1951 (dummy): ... rather than here.
1953 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1954 and Andreas Schwab <schwab@suse.de>

1959 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1961 * configure.ac (AC_PREREQ): Require version 2.60, for
1962 AC_PROG_SED, AC_PROG_GREP.
1964 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>

1974 2007-11-03 Eric Blake <ebb9@byu.net>
1976 Support m4 1.4.5 in testsuite.
1977 * tests/torture.at (Define a newline): Exclude line numbers in
1979 Reported by Ralf Wildenhues.
1981 2007-11-03 Jim Meyering <meyering@redhat.com>
1983 Remove automake-provided files from version control.
1984 * build-aux/elisp-comp: Remove file.
1985 * build-aux/install-sh: Remove file.
1986 * build-aux/missing: Remove file.
1987 * build-aux/mdate-sh: Remove file.
1988 * build-aux/.gitignore: New file.
1989 Suggestion from Ralf Wildenhues.
1991 2007-11-03 Eric Blake <ebb9@byu.net>
1993 Adjust version comparison to account for git snapshot numbers.

1995 component separator.
1996 * doc/autoconf.texi (Number processing Macros)
1997 <m4_version_compare>: Document this change.
1998 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2000 2007-10-30 Bruno Haible <bruno@clisp.org>
2002 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2003 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2004 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2005 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2006 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2007 Suggested by Paul Eggert.
2009 2007-10-28 Jim Meyering <meyering@redhat.com>
2011 * README-hacking: Autoconf, Automake, and Perl are required to build.
2012 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2014 2007-10-28 Jim Meyering <meyering@redhat.com>
2016 README-hacking: Recommend running autoreconf -vi.
2017 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2018 so that we use just-built tools when they're available.
2019 Suggestions from Ralf Wildenhues.
2021 2007-10-28 Jim Meyering <meyering@redhat.com>
2023 Make inter-release --version output more useful.
2025 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2026 which indicates that it is built using the 19th change set
2027 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2028 is a prefix of the commit SHA1.
2029 * build-aux/git-version-gen: New file.

3338 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3339 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3340 works but the latter doesn't, then it's a valid type.

3342 For C++ there doesn't seem to be a simple solution, so leave it alone.
3343 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3344 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

3513 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3515 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3516 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3517 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3518 substitution will still be done by the special code.
3519 Report by Jim Meyering.
3521 * doc/autoconf.texi (File System Conventions): Mention that
3522 $PATH_SEPARATOR is for the build system only.
3523 Report by Keith Marshall.
3525 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3527 * doc/autoconf.texi (Setting Output Variables): Mention that
3528 all non-NUL characters are ok in substituted values.
3529 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
3530 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
3531 carriage return for $AWK, needed for BSD awk.
3532 * tests/torture.at (Substitute and define special characters):
3533 Test all 8 bit non-NUL characters.
3534 Report against Automake by Patrick Welche.
3536 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3538 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3540 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3542 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3543 early on the reader side, drop stderr of the input to avoid
3544 `broken pipe' error output; this may happen even with shell
3545 builtin `echo' of some bash versions. Reports by Ian Macdonald
3546 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3548 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3550 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3551 separate items of `ac_user_opts', to avoid long lines.
3552 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3554 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3556 * doc/autoconf.texi: Fix some typos.
3558 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3560 Fix some wording problems noted by Paolo Bonzini in:
3561 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3562 * doc/autoconf.texi (Signed Overflow Examples): Give more
3563 discussion about the allow_superuser_privileges example,
3564 and change it a bit to make things clearer.
3565 (Optimization and Wraparound): Clarify whether the compiler
3566 will generate an infinite loop for the example derived from
3567 Autoconf's mktime test.
3568 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3569 Also, clarify unsigned multiplication overflow.
3571 2007-01-04 Eric Blake <ebb9@byu.net>
3573 * bin/Makefile.am (RELEASE_YEAR): New macro.
3574 (edit): Use it to supply correct copyright year to scripts.
3575 * bin/autoconf.as (version): Use it.
3576 * bin/autoheader.in ($version): Likewise.
3577 * bin/autom4te.in ($version): Likewise.
3578 * bin/autoreconf.in ($version): Likewise.
3579 * bin/autoscan.in ($version): Likewise.
3580 * bin/autoupdate.in ($version): Likewise.
3581 * bin/ifnames.in ($version): Likewise.
3583 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3585 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3586 feedback. The most important changes document what happens when
3587 you convert an out-of-range value to a signed integer type, and
3588 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3591 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3592 rewrite, taking notions from the recent discussion on the gcc and
3593 autoconf mailing lists; please see
3594 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3595 and follow the many links.
3596 (Integer Overflow Basics, Signed Overflow Examples):
3597 (Optimization and Wraparound, Signed Overflow Advice):
3598 (Signed Integer Division): New sections.
3600 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3602 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3603 preprocessor macro arguments in traced name.
3604 * doc/autoconf.texi (Defining symbols): Document longstanding
3605 support for AC_DEFINE-ing macros with arguments, and document
3606 behavior when the same variable has multiple AC_DEFINEs.
3607 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3608 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3609 macros directly, giving much shorter and simpler code.
3611 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3613 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3614 space before "$ac_configure_args" to prevent a 'config.status
3615 --recheck' failure if ac_configure_args doesn't contain a leading
3616 space. This works around a problem with the XEmacs configure.ac,
3617 which uses the (undocumented) ac_configure_args variable
3618 inconsistently with Autoconf.
3620 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3622 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3623 Include <limits.h>, and use its INT_MAX to rewrite the
3624 j loop so that it does not overflow 'int'. Problem reported by
3626 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3627 Play it safe by shifting left by 1 rather than multiplying by 2,
3628 as GCC is less likely to optimize this away when the value
3629 is signed (when it assumes overflow leads to undefined behavior).
3630 Also, don't assume time_t uses two's complement.
3632 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3634 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3635 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3636 dumps core on it. Report by Tim Rice.
3638 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3640 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3641 --disable-option-checking to --help output even when
3642 AC_PRESERVE_HELP_ORDER is not used.
3643 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3644 --with argument, rather than argument with [-.] replaced by
3646 * NEWS: Fix typo in previous change; the news was in the
3649 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3651 * NEWS: Warnings are now generated by default for unknown
3652 --enable-* and --with-* options.
3653 * doc/autoconf.texi (Option Checking): Renamed from
3654 (Configure Option Checking). Tighten up the wording a bit.
3655 (External Software, Package Options): Cross-reference to Option
3656 Checking, and use this to shorten our section.
3657 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3658 "$x" to test "x$foo" != x.
3659 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3660 Don't warn if $enable_option_checking is "no".
3661 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3662 ac_unrecognized_opts to the empty string.
3663 Don't echo the unrecognized opts, as this might mishandle
3664 backslashes or leading -.
3665 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3666 usage next to the other --disable-FEATURE options in the
3669 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3671 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3672 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3673 Print warning for unrecognized --with and --enable options
3674 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3675 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3676 Disable option checking when subdirs are configured.
3677 (AC_OUTPUT): If warnings are enabled, print warning about
3678 unrecognized --with and --enable options at the end of
3679 the configure output (as well as at the beginning).
3680 * doc/autoconf.texi (Option Checking): New node.
3681 Document new option warning functionality.
3683 2006-12-16 Eric Blake <ebb9@byu.net>
3685 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3686 * NEWS: Start news for current version.
3688 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3690 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3691 Define HAVE_GETMNTENT to 1, not to the empty string.
3692 Problem originally reported by Jochen Friedrich in
3693 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3695 This change prompted by a problem report by Andrey Simonenko in
3696 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3697 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3698 object-like macros only, in the traditional portable character
3700 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3701 Warn about attempts to define things that are not identifiers.
3702 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3703 awful hack that AC_DEFINEd macro names containing parentheses.
3705 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3707 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3708 too drastic, even if Texinfo in theory requires it for info mode.
3710 (config.status Invocation): Renamed back from Recreating a
3712 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3713 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3715 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3717 * NEWS: Version 2.61a.
3719 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3720 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3722 * NEWS: Document changes with echo and printf, and the lack
3723 of limits on the total size of multi-line values of substituted
3724 variables, and the AC_FUNC_FSEEKO fix.
3726 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3728 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3729 Writing configure.ac.
3730 (Autoconf Input Layout): Renamed from configure.ac Layout.
3731 (Recreating a Configuration): Renamed from config.status Invocation.
3732 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3733 (acconfig Header): Renamed from acconfig.h.
3734 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3735 (Writing Testsuites): Renamed from Writing testsuite.at.
3736 (Autom4te Cache): Renamed from autom4te.cache.
3738 * BUGS: Remove mention of VPATH problem, since it's now documented
3739 not to be a bug in the Autoconf build procedure itself, but rather
3740 a problem with the proprietary `make' programs.
3742 * doc/autoconf.texi (Build Directories): Add a cross reference
3745 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3746 * doc/standards.texi: Sync from gnulib.
3748 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3749 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3750 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3751 generated automatically.
3753 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3755 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3756 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3757 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3759 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3761 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3762 `CEOF$ac_eof' special marker, the awk script cannot contain a
3763 line matching `^CEOF', so this is not needed any more.
3764 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3765 special marker in the test.
3767 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3769 * tests/tools.at (autom4te preselections): Use `find -newer';
3770 remove one of the sleeps.
3772 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3773 more readable, using ...
3774 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3776 * doc/autoconf.texi (autoheader Invocation): Do not double-
3777 quote the parameter of `AH_BOTTOM' in the example.
3779 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3781 * doc/autoconf.texi (Configuration Headers): Remove the
3782 example with multiple input files.
3783 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3784 multiple input files.
3786 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3788 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3789 creating the awk substitution script, handle one input line at a
3790 time, so that the maximum length of a substituted (multi-line)
3791 value is not limited by the size of the sed pattern space.
3792 The trade-off is a slightly repetitive sed script.
3793 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3794 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3795 * tests/torture.at (Substitute a 2000-byte string): Increase the
3796 test with several long lines, they should not be caught by sed
3799 * tests/tools.at (autom4te preselections): New test, to flag
3800 entries missing from autom4te.cfg.
3801 Report by David Byron <dbyron@hheld.com>.
3803 * tests/torture.at (Substitute a 2000-byte string): Actually use
3804 AC_PROG_AWK, so the last change works as intended.
3805 (Substitute and define special characters): Likewise.
3806 (Substitute a newline): Likewise.
3808 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3809 instead of `awk' consistently.
3810 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3811 * tests/torture.at (Torturing config.status): Test both the
3812 result of AC_PROG_AWK and plain awk.
3813 (Substitute a 2000-byte string): Likewise.
3814 (Substitute and define special characters): Likewise.
3815 (Substitute a newline): Likewise.
3817 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3819 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3820 can be assigned to a function pointer. Problem reported by
3821 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3822 part of a patch by Ralf Wildenhues in that same bug report.
3824 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3826 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3827 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3829 2006-12-01 Eric Blake <ebb9@byu.net>
3831 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3832 cross-compiling from cygwin to mingw.
3833 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3834 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3835 to lib/autoconf/c.m4.
3837 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3839 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3840 string for more reliable failure. Wrap the entire test that
3841 causes the broken Solaris printf to dump core, in a subshell,
3842 so the segmentation fault message is reliably suppressed.
3843 Fix shell expansion errors by using /usr/ucb/echo always;
3844 avoid an error on systems without it by another subshell.
3845 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3846 subshell-$as_echo to `as_echo', for better error message.
3848 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3850 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3851 `BASH_SOURCE' contain a newline, set them to empty, as they may
3854 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3856 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3857 years and is too hard to maintain now. The last straw was
3858 reported by Jerker Baeck in
3859 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3860 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3861 * doc/autoconf.texi (Particular Functions): Move
3862 AC_FUNC_SETVBUF_REVERSED from here...
3863 (Obsolete Macros): ... to here. Say that it does nothing now.
3864 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3865 Turn into (almost) a no-op.
3867 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3869 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3870 These macros are obsolescent and new applications shouldn't need them.
3871 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3872 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3873 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3874 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3875 (AC_FUNC_VPRINTF): Likewise.
3876 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3877 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3878 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3880 * doc/autoconf.texi (Setting Output Variables): Mention that
3881 @VAR1@VAR2 has unspecified behavior. Problem reported by
3883 * NEWS: Mention this.
3885 * Makefile.am: Put only a single '#' into the copyright notice,
3886 so that it's also present in the output file. Standardize wording
3887 in makefile copyright notices to match GNU coding standards.
3888 * bin/Makefile.am: Likewise.
3889 * doc/Makefile.am: Likewise.
3890 * lib/Makefile.am: Likewise.
3891 * lib/freeze.mk: Likewise.

3893 * lib/autoscan/Makefile.am: Likewise.
3894 * lib/autotest/Makefile.am: Likewise.
3895 * lib/m4sugar/Makefile.am: Likewise.
3896 * man/Makefile.am: Likewise.
3897 * tests/Makefile.am: Likewise.
3898 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3901 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3903 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3904 in the sed script that mangles the awk script: delete up to the
3905 first exclamation mark only.
3906 * tests/torture.at (Substitute and define special characters):
3909 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3911 Rewrite config files generation: avoid quadratic growth in
3912 the number of substituted variables by using awk instead of sed
3913 for the bulk of the substitutions.
3914 * NEWS: Mention this.
3915 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3916 forbidden in the output (and thus input) file.
3917 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3918 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3919 generate just one large awk script for substitutions,
3920 eliminating much of the earlier complexity, while adding some
3921 new complexity. Only expand the substitution templates at
3922 configure time, for smaller configure script size. If
3923 _AC_SUBST_FILES are used, test 'awk' for working getline support
3924 at config.status time. If absent, interpolate through the
3925 shell. The awk script was written with much help
3926 from Paolo Bonzini and Paul Eggert.
3927 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3928 (_AC_SED_FRAG_NUM): Likewise.
3929 (_AC_SUBST_CMDS): Renamed from...
3930 (_AC_SED_CMDS): ...this.
3931 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3932 * tests/torture.at (Substitute a 2000-byte string): Also
3933 substitute a line with 1000 words, and a variable with several
3935 (Substitute and define special characters): Test awk special
3936 characters, and put substitution input strings `@foo@' in the
3937 output, to test that no recursion happens; test several other
3938 combinations from Paolo Bonzini.
3940 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3942 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3943 that replaced echo with AS_ECHO where this wasn't necessary.
3944 Problem reportd by Ralf Wildenhues.
3945 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3946 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3947 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3949 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3951 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3953 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3955 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3956 that traditional Awk lacks 3-arg "split". It has it.
3957 Mention that FS must be a single character, and a few other
3958 99-byte limits of traditional Awk.
3959 Mention that if (i in a) doesn't work with traditional Awk.
3961 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3963 * tests/autotest.at (BSx641-newline in command):
3964 (BS-BS-newline in command, BSx640-newline in command):

3968 Use printf '%s\n' instead of echo, for portability to hosts
3969 where echo interprets backslashes. This will break on hosts
3970 that lack printf, but for now let's assume all such hosts
3971 are dead (if not, we should get reports of test failures).
3973 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3975 'echo' has some portability problems, when given a first argument

4167 Single-quote in a test title,
4168 Double-quote in a test title): Don't expect failure anymore.

4181 * tests/torture.at (#define header templates): M4-quote this title in
4182 AT_SETUP call so that no M4 code is commented inadvertently somewhere.

4187 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4188 `trap ... 0' inside a function, for AIX sh.
4190 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4192 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4193 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4194 5363) simply issues a warning when dividing by zero at compile
4195 time. Problem reported by Elias Pipping.
4197 2006-10-26 Eric Blake <ebb9@byu.net>
4200 * doc/autoconf.texi (Evaluation Macros): Improve the example to

4229 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4230 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4231 reported by Nelson H. F. Beebe for Coreutils 6.4.
4233 * tests/tools.at (autoconf --trace: user macros): Remove test
4234 for tracing multiline macros, since m4 1.4.7a uses a different
4235 way to number lines. Problem reported by Ralf Wildenhues.

4311 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4313 (Imported from Automake.)
4314 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4315 which incorrectly sets the mode of an existing destination
4316 directory. In some cases the unpatched install-sh could do the
4317 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4318 system. We hope this is rare in practice, but it's clearly worth
4319 fixing. Problem reported by Alex Unleashed in
4320 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4321 Also, don't bother to check for -m bugs unless we're using -m;

4401 Use a better substitute, by inspecting the output of "ls"
4402 rather than just using ":".
4403 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4404 rather than AS_EXECUTABLE_P, since we needn't worry about
4405 non-regular files here.
4407 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,

4436 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4437 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4439 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4440 with werror_flag and conftest.err and so forth. This is more
4441 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4442 and anyway the user shouldn't normally want to see this gorp logged.
4443 Problem reported by Ralf Wildenhues.
4444 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4445 empty, not 'no', since the rest of the code uses 'test -z'.

4456 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4457 than creating a file to use with test -x; this is much faster.

4716 broken lex libraries like native ia64-hp-hpux11.22; see
4717 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4881 * doc/autoconf.texi (config.status Invocation): Adjust according
4884 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4886 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
4887 --help' should mention that `--version' outputs configuration
4888 settings. Report by Bruno Haible.
4890 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4892 Fix test suite failures reported by Pierre in
4893 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
4894 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
4895 the compiler created a file "b.out" when it didn't create anything
4897 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
4898 Discard stderr too, when invoking the test script.
4900 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
4902 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
4903 in the restoring of the werror flag.
4905 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4907 * doc/autoconf.texi (Volatile Objects): Be even a little
4908 less skeptical about "volatile", after discussion with
4909 Bruno Haible on bug-gnulib.
4910 (Limitations of Usual Tools): Warn about sed stripping
4911 leading white space from text. From Bruno Haible.
4913 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4915 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4916 compiler complains about it, even if things works after the
4917 complaint. Problem reported by Peter O'Gorman.
4919 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4920 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4921 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4923 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4925 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4926 after -R regardless of host. Patrick Welche reports that this
4927 fixes things on NetBSD 3.99.
4929 * NEWS: Recommend M4 1.4.5.
4931 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
4932 * tests/tools.at (autom4te cache): Update wording of diagnostic
4935 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4937 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4938 under AC_C_VOLATILE.
4939 (Volatile Objects): Be a little less skeptical about what
4940 "volatile" means. Derived from thoughts by Ben Pfaff in
4941 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4943 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4945 * doc/autoconf.texi: Fix some typos.
4947 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4949 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4950 more globally, since the 2006-06-30 patch didn't suffice. Problem
4951 reported by Keith Marshall. Also, don't bother with builddir2,
4952 since it shouldn't be needed any more.
4954 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4956 * doc/autoconf.texi (Generic compiler characteristics):
4957 Document AC_COMPUTE_INT. Fix wrong statements on Default
4958 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
4960 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
4961 (_AC_COMPUTE_INT): Add obsoletion warnings.
4962 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
4965 * NEWS: Document change.
4967 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
4969 * doc/autoconf.texi (Volatile Objects): New section.
4971 * NEWS: Document previous change.
4973 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4975 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4976 Require that long long int be at least 64 bits wide. C99 requires
4977 this and enough programs depend on it so we should check for it.
4978 Bruno Haible reports in
4979 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4980 that long long int is 32 bits wide with some nonstandard compilers.
4981 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4983 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4985 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4986 to a nonexistent file, so that we don't have to worry about
4987 a local site configuration that doesn't use /usr/local.
4988 Problem reported by Keith Marshall in
4989 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4991 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4993 * doc/autoconf.texi: Be more consistent about using @acronym with
4994 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4995 quite right (it talked about "OSF/Tru64", even though the
4996 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4997 and it even mentioned "OSF 4"!) and at this point there's little
4998 reason to talk about OSF any more, since it died in 1994.
4999 (Specific Compiler Characteristics): Simplify example of
5000 negative-size array.
5001 (File Descriptors): Reorder to make the text flow better.
5002 Remove joke about "appreciate the various levels"; I didn't get it.
5003 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5004 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5005 (File Descriptors, Limitations of Usual Tools):
5006 Tone down the advice against renaming or removing open files.
5007 (Limitations of Usual Tools): Add a new section, on 'rm'.
5009 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5011 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5012 -lXt in LIBS, idea from Karsten Hopp; this was due since
5015 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5016 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5017 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5018 (which belong to Xt, not X itself). See Debian bug 327655.
5020 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5022 * configure.ac (AC_INIT): Bump to 2.60a.
5025 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5029 * configure.ac, NEWS: Update.
5031 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5033 * config/texinfo.tex: Sync from upstream.
5035 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5036 quadrigraph correctly in traces.
5038 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5041 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5042 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5044 * doc/autoconf.texi (Changed Directory Variables): New node,
5045 to document the whole `datarootdir' business a bit better.
5047 * tests/torture.at (datarootdir workaround): Extend test.
5048 Prompted by report by Alexandre Julliard.
5050 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5052 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5053 when using default mode of IBM C 6 for AIX. Problem and two-line
5054 fix reported by Larry Jones.
5056 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5058 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5059 about literal '${datarootdir}' if a definition is found in the
5062 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5064 * NEWS: Use "M4" rather than "m4" when appropriate.
5065 Problem reported by Eric Blake.
5066 * doc/autoconf.texi: Likewise.
5067 Use @acronym around BSD, GCC, and GNU when appropriate.
5068 (Why GNU M4): Renamed from "Why GNU m4".
5069 (Redefined M4 Macros): Mention that Posix
5070 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5071 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5074 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5076 * bin/autom4te.in (handle_output): Do not forbid the empty
5078 * tests/tools.at (autoconf: the empty token): New test.
5080 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5082 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5083 calls, so that we do not care whether they are LIFO or FIFO;
5084 in the m4_wrap, do not check which diversion is the topmost
5085 one, just check that the stack is balanced at the end.
5086 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5087 base diversion forever--pop the previous diversion before
5088 opening the new one; consequently, remove the m4_wrap call.
5089 * lib/autotest/general.m4 (AT_INIT): Likewise.
5090 * tests/m4sugar.at: Do not use
5091 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5093 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5094 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5096 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5097 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5098 Rework example of m4wrap token-pasting trouble so that it doesn't
5099 care whether it's LIFO or FIFO.
5100 Fix some "contrary to"s that are awkward in English.
5102 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5104 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5105 to `yes' instead of `int$1_t' if the type is found, for more
5106 consistent configure output (where $1 is the number of bits).
5107 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5108 Suggested by Bruno Haible.
5110 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5111 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5112 with system headers. Report by Bruno Haible.
5114 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5116 * config/config.guess, config/config.sub: Sync from upstream.
5118 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5119 in order to avoid picking up an older installed frozen m4sh.m4f.
5120 Besides an outdated shell startup, this could have been created
5121 by an earlier M4 version with incompatible frozen file format.
5123 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5125 * README: Recommend m4 1.4.4 instead of 1.4.3..
5126 * doc/autoconf.texi: Likewise.
5127 (Special Chars in Names): Say that $(.FOO) is portable, as
5128 suggested by Stepan Kasal.
5129 (Installation Directory Variables, Build Directories):
5130 (Automatic Remaking, Subdirectories, Fortran Compiler):
5131 (Making testsuite Scripts, Defining Directories):
5132 Quote variable usages better.
5133 (Making testsuite Scripts): Add clean-local rule to makefile
5134 snippet, by Eric Blake.
5135 (Installation Directory Variables): Fix table item font.
5136 Reword slightly to clarify. Generalize advice about
5137 not using special characters to include all file-related
5138 vars, not just VPATH.
5139 (Special Chars in Variables): Warn about special characters in
5141 (Assignments): Clarify default-value example as suggested by
5143 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5144 (Special Shell Variables): Note leading ./ or ../, as suggested
5146 (Limitations of Builtins): Under cd, warn about CDPATH.
5147 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5150 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5152 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5153 `@var', for texi2html.
5154 (Systemology): Some more word wrapping, for DVI output.
5155 (autom4te Invocation): The short option for `--melt' is `-M',
5158 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5160 * doc/autoconf.texi: More formatting and English tweaks,
5161 many suggested by Ralf Wildenhues.
5162 Reword to avoid "@code{...}'s" and the like, since it's ugly
5163 with Emacs info mode. discontents -> woes.
5164 Put a few "will"s back. time stamp -> timestamp.
5165 side-effect -> side effect.
5167 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5169 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5170 Warn about $@ not persisting. Problem reported by Julien Danjou in
5171 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5172 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5173 Mention other special chars, too.
5175 2006-06-14 Eric Blake <ebb9@byu.net>
5177 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5179 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5181 * doc/autoconf.texi: Some systematic minor improvements, as
5182 follows. Use "makefile" when talking about makefiles
5183 generally (which might be named "makefile" or "Makefile" or even
5184 "foo.mk"), "Makefile" when talking about a specific makefile
5185 called "Makefile". This unclutters the text from weird quotes
5186 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5187 values" rather than "@var{foo}s" and similar constructs containing
5188 "}s". Use "Make rules" rather than "Makefile rules". Minor
5189 English-language improvements. Change the prefix "sub-" to "sub"
5191 Put blank lines around examples more consistently.
5192 Avoid "rather" and "very" as intensifiers.
5193 Avoid "will" as an auxiliary.
5194 (Limitations of Make): Split this node into....
5195 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5196 (Leading _ in Macro Names, Backslash-Newline-Newline):
5197 (Backslash-Newline Comments, Long Lines in Makefiles):
5198 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5199 (obj/ and Make, make -k Status, VPATH and Make):
5200 (VPATH and Double-colon, $< in Explicit Rules):
5201 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5202 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5203 New nodes, resulting from splitup of Limitations of Make.
5204 All cross-references changed. Raise the top node from
5205 a section to a chapter, and all subnodes accordingly.
5206 Redo the introductory wording to match the new organization.
5207 (Installation Directory Variables): Use an example that is
5208 closer to what Autoconf actually does. Mention that VPATH's
5209 value should not contain metacharacters or white space.
5210 (Fortran Compiler): Fix a VPATH bug in an example.
5211 (Leading _ in Macro Names): Mention that this problem is no longer
5212 of practical concern.
5213 (VPATH and Make): Reword the advice to make it clearer
5214 that Autoconf and Automake support VPATH in non-GNU make, but
5215 many packages have bugs in this area.
5216 ($< in Explicit Rules): Refer to Build Directories rather
5217 than using a (non-VPATH-safe) example.
5218 (Automatic Rule Rewriting): Mention the sort of disaster that
5219 can ensue with Solaris-style rule rewriting with VPATH.
5221 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5223 * doc/install.texi (Compilers and Options): Weaken the
5224 suggestion to use GNU make for VPATH builds.
5226 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5227 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5229 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5230 in regular expression.
5232 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5234 * doc/autoconf.texi (Installation Directory Variables):
5235 Drop extra @samp from `@table @samp' item.
5236 (Limitations of Usual Tools): Comment fix.
5237 Do not nest @samp just to point to other table items.
5238 (Writing testsuite.at) <AT_CHECK>: The second argument to
5239 `@dvar' is already @samp'ed.
5240 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5241 do not use @var in the second argument.
5243 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5245 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5246 $as_shell.exe too. Problem reported by Andreas Buening in
5247 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5249 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5251 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5252 `unused variable' compiler warning, for `-Wall -Werror'.
5253 Reported by Jaap Haitsma in
5254 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5256 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5258 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5259 case the compiler dumps core. Problem reported for
5260 OpenServer 5.0.7 by Tim Rice in
5261 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5262 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5265 2006-06-06 Tim Rice <tim@multitalents.net>.
5267 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5268 "ERROR" only shows up in "make check" output if there is an

5292 * config/texinfo.tex: Sync from upstream.
5294 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5295 seen, invoke libtoolize with `--ltdl' argument.
5296 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5298 Suggested by Eric Blake.
5300 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

5345 Prefer "current" to "modern" to describe
5346 currently-used (albeit perhaps old-fashioned) hosts.
5347 Mention which ancient features no longer need to be worried about.
5348 setgid -> set-group-ID
5349 setuid -> set-user-ID (these are the Posix terms)

5362 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5363 Mention that it's now safe to use 3 and 4.
5364 (Limitations of Usual Tools): cp -r is now specified by Posix.
5365 Omit longwinded and obsolescent discussion of cp -f.
5366 Modernize discussion of expr, ls.
5367 (Limitations of Make): Modernize discussion of VPATH builds.
5368 Mention $? as a workaround in some cases.
5369 * doc/install.texi (Basic Installation):
5370 Mention "./configure; make; make install" first. Be more
5371 specific about why this file is generic. Remove unnecessary
5372 parens. Remove misleading "only". Remove obsolete advice
5373 about csh. Don't say "configure" takes awhile; say it
5374 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5375 and CC=c99 rather than CC=c89, as these are blessed by current
5376 Posix. Recommend GNU make if doing a VPATH build.
5378 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5380 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5381 examples involving shell prompts.
5383 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5384 and Paul Eggert <eggert@cs.ucla.edu>
5386 * doc/autoconf.texi (Here-Documents): Add details about the
5387 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5388 use "here-documents" instead of "here documents".
5390 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5392 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5394 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5396 * doc/autoconf.texi (File System Conventions): Warn about ":"
5397 anywhere in directory names.
5399 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5401 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5402 about quoting the case statement, just in case.
5403 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5404 was fixed in ksh93g; reported by Ralf Wildenhues.
5406 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5408 * doc/autoconf.texi (System Services): Do not document
5409 overriding EXEEXT via ac_cv_exeext=ext.
5410 (Particular Programs) <AC_PROG_MKDIR_P>:
5411 Document that ${MKDIR_P} understands --.
5412 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5415 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5417 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5418 argument with leading hyphen. Problem reported by Paul Eggert.
5420 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5422 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5423 about quoting ac_try: quote all of it, if any of it seems suspicious.
5424 This means we don't have to worry about ${ or sed any more.
5425 Also, double-quote the case statement, to work around misuses via
5426 underquoting as reported by Ralf Wildenhues in
5427 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5428 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5429 undocumented and dangerous macro.
5430 Problem reported by Ralf Wildenhues in
5431 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5433 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5435 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5436 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5437 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5439 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5441 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5442 since evidently some packages rely on the old, broken behavior.
5443 Problem reported by Ralf Wildenhues in
5444 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5445 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5446 pre-2006-05-26 definitions, but leave in the comments that
5447 these macros are dangerous and should not be used.
5448 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5449 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5450 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5451 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5452 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5454 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5456 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5457 the use of 'tr', since this is our only use of 'tr'.
5459 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5460 and Paul Eggert <eggert@cs.ucla.edu>
5462 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5463 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5465 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5467 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5468 the output file in the `${datarootdir}' test.
5470 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5471 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5473 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5474 mention of `datarootdir' in the input file(s), but literal
5475 `${datarootdir}' in the output file, and we haven't warned yet,
5476 then warn as well: the user may have (erroneously) used
5477 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5478 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5479 * tests/torture.at (datarootdir workaround): Extend this test.
5482 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5483 and Paul Eggert <eggert@cs.ucla.edu>
5485 * doc/autoconf.texi (autoheader Invocation): The first argument to
5486 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5487 alternatives and clear up the language a bit.
5489 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5491 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5492 ac_config_guess, ac_config_sub, ac_configure.
5493 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5494 Fix typo that prevented an unnecessary space from being removed.
5495 Problems reported by Ralf Wildenhues in:
5496 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5498 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5500 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5501 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5502 Don't use the term "thread-safe" to talk about mkdir race
5503 conditions, since the problem is more a process than a thread
5504 issue. Problem reported by Stepan Kasal in:
5505 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5506 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5507 the test for 'install' more closely. Look at MKDIR_P first.
5508 Look in the PATH, and at /opt/sfw/bin.
5509 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5510 Don't bother to try mkdir -p, since we already check mkdir --version;
5511 just look at the version number. (There's no easy way to check
5512 for race-free implementations.)
5513 * tests/tools.at (autoconf: subdirectories): Adjust to above
5514 changes, since MKDIR_P now might end in "/mkdir -p".
5516 * doc/autoconf.texi (autoheader Invocation): Mention that the
5517 first arg of AC_DEFINE_UNQUOTED must be a literal.
5518 Problem reported by Ben Pfaff in
5519 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5521 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5522 * doc/autoconf.texi (Special Chars in Variables): New section.
5523 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5524 (Installation Directory Variables): Quote $(datadir) better.
5525 (Limitations of Builtins): Describe some of eval's trickiness.
5527 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5528 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5529 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5530 in front of every arg, not just trailing args. Quote apostrophes.
5531 (_AC_EVAL_ECHO): New macro.
5532 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5533 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5535 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5536 exposed by quoting of eval argument. Put the command on line line
5538 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5539 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5540 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5541 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5542 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5543 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5544 Use eval more safely.
5545 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5546 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5548 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5549 lines, exposed by quoting of eval argument.
5551 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5552 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5554 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5555 initialization of `ac_cv_exeext', do not override it if it was
5556 already set, unless it was set to `no', for compatibility with
5557 Autoconf-2.13, and comment this.
5558 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5559 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5560 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5561 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5562 Document that this test may be overridden by setting
5565 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5567 Revert these two patches:
5569 2006-04-06 Eric Blake <ebb9@byu.net>
5570 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5571 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5574 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5575 Clean up _AC_COMPILER_EXEEXT* macros.
5576 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5577 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5578 ac_file to the name of the default output file and call
5579 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5580 initial `rm' of the candidate files...
5581 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5582 the same list in subsequent `rm' calls, and for the temporary
5583 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5584 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5585 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5586 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5587 no longer needed) by libtool. Make it a cache check.
5588 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5589 copied here by mistake.
5590 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5591 _AC_COMPILER_EXEEXT.
5592 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5593 _AC_COMPILER_OBJEXT directly.
5594 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5596 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5598 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5599 Fix description of how the buggy `sed' works.
5601 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5605 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5606 ENOLCK. Only mention `make -j' when applicable. Only raise
5607 fatal errors when `make -j' is involved. Improve error message.
5609 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5611 * doc/autoconf.texi (Here-Documents): We now know more about
5612 the variable expansion in here documents bug.
5613 Thanks to Tim Rice and Stepan Kasal.
5615 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5616 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5618 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5620 * tests/autotest.at (Multiline command from M4 expansion):
5621 No failure to be expected if the shell quotes newlines in
5622 commands in the `set -x' output. Report by Tim Rice.
5625 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5627 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5628 expansion in the here-documents used by config.status, as that
5629 runs afoul of the Korn shell version M-12/28/93d bug described in
5630 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5631 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5632 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5634 2006-05-23 Jim Meyering <jim@meyering.net>
5636 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5637 Fix typo introduced with 2006-04-02 change. It reversed the sense
5640 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5642 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5643 ac_dB slightly, to save bytes in the script.
5644 Max out at 50 lines, rather than 96; this is more likely
5645 (though not guaranteed) to avoid obscure 'sed' failures.
5647 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5649 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5650 `tr -d -' as bad option argument. Work around this by deleting
5651 an unrelated character.
5652 Report by Tim Rice <tim@multitalents.net>.
5654 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5655 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5656 Stepan Kasal <kasal@ucw.cz>
5658 * doc/autoconf.texi (Particular Programs): Do not promise that
5659 we always prefer the GNU version of the program, and that we
5660 search according to PATH; both rules can have exceptions.
5661 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5662 AC_PROG_SED. Move descriptions of limitations
5663 to the Limitations of Usual Tools section.
5664 (Limitations of Usual Tools) <sed>: Mention script length
5665 limitations with Solaris /usr/ucb/sed.
5666 <grep>: Fix wording for empty alternative. Mention that -c and
5667 -l should not be combined, and that -E and -F should not be
5670 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5671 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5673 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5674 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5676 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5678 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5679 AC_DEFINE is now passed to m4_pattern_allow.
5680 * NEWS: Mention that; likewise for AC_SUBST.
5681 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5682 the parameter to m4_pattern_allow.
5683 * tests/tools.at: Add a check for that.
5685 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5687 * lib/autoconf/status.m4: Fix typos.
5689 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5691 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5692 only the files that this macro generates.
5694 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5696 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5697 the HP-UX sed limitation of 99 commands, labels do not count.
5698 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5700 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5702 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5704 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5705 Import the following fix from coreutils:
5707 2006-01-13 Jim Meyering <jim@meyering.net>
5709 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5710 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5711 not double-quote uses of that variable, to accommodate the rare
5712 case in which getmntent is available in none of the libraries
5713 checked. This happens at least on FreeBSD 5.0.
5715 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5717 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5718 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5719 some other programs unwisely rely on these undocumented vars.
5720 But put in warning comments about them.
5721 Problem reported by Ralf Wildenhues in
5722 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5723 * NEWS: Document that these variables are intended to go away.
5725 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5727 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5728 and set the language to C++ (analogous to the equivalent Fortran
5731 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5732 * doc/autoconf.texi (C++ Compiler): Document it.
5733 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5736 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5738 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5739 that caused config.status to generate 100-command sed scripts; the
5740 portable limit is 99.
5742 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5744 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5745 variable `ac_d' instead of `d' to avoid infringing namespace.
5746 Report by Ralf Menzel.
5748 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5750 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5751 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5752 * tests/tools.at (autoconf: subdirectories): New test, taken from
5753 the corresponding problem report by Ralf Wildenhues in:
5754 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5756 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5757 Quote some uses of shell variables if they might suffer unexpected
5758 globbing. This doesn't fix all instances of quoting problems that
5759 I found, just the easy ones that look safe.
5760 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5761 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5762 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5763 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5764 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5765 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5771 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5773 * bin/autoreconf.in ($help): Reword according to the manual.
5774 Suggested by Olly Betts.
5776 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5777 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5779 * bin/autoreconf.in: Pass the directory argument to
5780 `require_configure_ac'. Fix comment.
5781 * tests/torture.at (Configuring subdirectories): Expose this.
5782 Reported by Olly Betts.
5784 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5786 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5787 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5788 Automake as follows:
5790 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5791 `$configure_in' instead of `configure.in', to preserve
5792 directory component.
5794 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5796 * config/config.guess, config/config.sub, config/texinfo.tex,
5797 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5799 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5801 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5802 test for C99 conformance; (bool) 0.5 is an integer constant
5803 expression, but (bool) -0.5 is not. Problem reported by Fedor
5804 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5806 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5808 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5809 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5810 Warn about obsolete install-sh files. Remove stray sentence
5811 fragment and fix cross reference.
5812 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5813 install -d; this undoes the 2006-05-10 change.
5814 (MKDIR_P): Mark with AN_MAKEVAR.
5815 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5816 that we don't require $INSTALL to be thread-safe. Move comments
5817 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5818 of AC_PROG_INSTALL. Output a message saying that we're checking
5819 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5820 MKDIR_P instead of AC_SUBST.
5821 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5822 Special magic for MKDIR_P, too.
5823 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5825 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5827 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5829 Sync from Automake, as follows:
5831 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5832 * config/install-sh: Initialize IFS, so field splitting isn't
5834 * config/mkinstalldirs: Likewise.
5835 * config/missing: Remove superfluous quotes. Replace all uses of
5836 `[' by `test', for consistency, and for..
5837 * config/missing (sed_minuso, sed_output): New variables.
5838 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5839 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5840 Fixes `missing' to detect `--output' for help2man. Fixes
5841 PR automake/483. Report by Dennis J. Linse.
5842 (autom4te): Document in `missing --help'.
5844 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5846 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5847 * config/install-sh: Don't use 'path' to talk about file names,
5848 as per GNU coding standards. Close a race condition reported by Ralf
5849 Wildenhues and Stepan Kasal. There is still a race condition
5850 on hosts that predate Posix 1003.1-1992, but we can't help this.
5851 Don't mishandle weird characters like space on pre-Posix hosts.
5852 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5853 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5854 AC_PROG_MKDIR_P from AS_MKDIR_P.
5855 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5856 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5857 earlier editions are not (including Automake 1.8.3).
5858 Do not suggest mkinstalldirs for thread-safety.
5859 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5860 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5861 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5862 presence of special characters and race conditions.
5863 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5864 in Autoconf's name space.
5866 2006-05-10 Bruno Haible <bruno@clisp.org>
5867 and Paul Eggert <eggert@cs.ucla.edu>
5869 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5870 from Automake with minor changes.
5871 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5873 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5875 * config/install-sh: Update to Automake CVS version, as follows:
5876 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5877 * lib/install-sh: Simplify the expr implementation of dirname.
5878 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5879 * lib/install-sh: Handle --, and diagnose unknown options.
5881 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5883 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5884 `./autom4te' to create `./testsuite', since the `all' target
5885 will ensure its presence, but `installcheck' should not create
5886 the uninstalled wrappers.
5888 * tests/torture.at (Unusual Automake input files): Skip if we
5889 detect automake < 1.8.
5891 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5893 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5894 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5895 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5898 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5900 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5901 munge (multiple) white space and other oddities.
5902 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5903 single quotes in variable assignment.
5904 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5905 and similar failures by adding multiple spaces, tabs, and other
5907 Report and different test suggested by Francesco Romani
5908 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5910 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5911 single quotes, we only need to search for single quotes; this
5912 both simplifies the search pattern, and makes us less
5913 susceptible to `echo' variations for arguments not containing
5915 (_AC_ARG_VAR_VALIDATE): Likewise.
5917 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5919 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5920 `$*' and IFS concatenation issue with traditional shells and
5921 bash-2.04. Report by Seanster@Seanster.com.
5923 2006-05-03 Bruno Haible <bruno@clisp.org>
5925 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5926 precisely which Mac OS X versions have the od problem.
5928 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5930 * doc/autoconf.texi: Use @option systematically.
5932 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5933 and Bruno Haible <bruno@clisp.org>
5935 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5937 (Integer Overflow): Mention the special case of integer division
5940 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5942 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5943 traditional shells like the Solaris one that do not use the
5944 first IFS character for assembling `$*'.
5945 Prompted by a related report from autoconf_bug@nro.ca.
5947 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5948 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5950 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5951 Mention more problems with the -e option.
5953 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5956 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5958 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5959 in URLs to improve DVI formatted output (requires texinfo 4.6).
5960 (System Services, Systemology, Shellology): Likewise.
5961 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5964 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5966 (Runtime): Fix macro argument names to match description:
5967 `action-if-found' -> `action-if-true' and similarly.
5968 (Obsolete Macros): Likewise.
5969 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5970 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5971 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5973 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5975 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5978 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5981 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5983 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5984 /bin/sh set unsorted output.
5985 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5986 * tests/local.at: Likewise.

5990 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5991 (Integer Overflow, Null Pointers, Buffer Overruns):
5992 (Floating Point Portability, Exiting Portably): New sections.
5993 (Writing Test Programs): Fix some langauge. Recommend exiting
5994 with status 1, not merely nonzero. Clarify exit declaration.
5995 (Run Time): Move C exit status stuff to new Exiting Portably section.
5996 (Systemology): Mention Posix and levenez. Update v7 reference.
5997 (Portable Shell): Mention the Posix shell.
5999 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6001 * bin/autoconf.as (me): Replace by as_me.
6003 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6005 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6006 since as_me isn't set yet.
6008 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6010 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6011 a few minor bugs in this area.
6013 * doc/autoconf.texi (Programming in M4sh): Comment out the
6014 documentation of AS_BASENAME, for now.
6015 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6016 (Limitations of Builtins) <basename>: Do not refer to
6018 * bin/autoconf.as (me): Don't use AS_BASENAME.
6019 (dir): Remove the unused variable.
6020 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6021 AS_DETECT_REQUIRED. All uses changed.
6022 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6024 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6025 (AS_BASENAME): Use "basename --" to protect against leading "-".
6026 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6027 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6028 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6029 (_AS_DIRNAME_PREPARE): Likewise.
6030 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6031 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6032 (AS_DIRNAME): Use "dirname --".
6034 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6036 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6037 of "run time" and "run-time" changed to "runtime", for consistency.
6038 * lib/autoconf/fortran.m4: Likewise (in comment).
6039 * lib/autoconf/functions.m4: Likewise.
6040 * lib/autoconf/general.m4: Likewise.
6041 * lib/autoconf/headers.m4: Likewise.
6043 * doc/autoconf.texi (Run Time): Document the exit status situation
6044 with more accuracy and detail.
6046 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6048 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6049 Archive is not officially `GNU' any more. Update URL.
6050 (Defining Directories): Likewise
6051 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6053 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6055 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6056 newline from the `trap' code to finish `config.log'; the NetBSD
6057 /bin/sh resets the exit status after an empty command, as
6058 documented in doc/autoconf.texi.
6059 Reported by Dalibor Topic <robilad@kaffe.org>.
6061 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6063 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6064 Suggested by Bruno Haible.
6066 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6068 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6069 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6070 Instead, just list the shells that we know work.
6071 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6072 changed. Be more cautious about the _cv_ variable.
6073 * tests/tools.at (Syntax of the shell scripts): Check the
6074 _cv_ variable once, at first, to avoid an internal autoconf error
6075 when sh -n does not work.
6077 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6079 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6081 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6083 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6084 use ">&-" since we're only 99.999% sure that this is portable,
6085 and since the MinGW bug is fixed in a different way.
6086 * lib/autotest/general.m4 (AT_INIT): Likewise.
6088 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6090 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6091 before opening config.log, to avoid hitting a bug on MinGW.
6093 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6095 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6096 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6097 This works around a MinGW bug reported by Eric Paire.
6098 Make sure that all writes to the log file append to it,
6099 rather than possibly losing data.
6100 * lib/autotest/general.m4 (AT_INIT): Likewise.
6102 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6104 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6107 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6111 * configure.ac (AC_INIT): Bump to 2.59d.
6113 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6117 * Makefile.maint (news-date-check): Do not require a leading `*'
6118 before the release date in NEWS.
6120 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6121 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6123 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6124 the instantiated file do not contain the string 'datarootdir'
6125 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6126 @mandir@, replace the reference '${datarootdir}' by the value.
6127 * tests/torture.at (datarootdir workaround): New test.
6128 * NEWS: Advertise this temporary fixup.
6129 Based on a patch by Bruno Haible, reported and analyzed by
6130 Paul Eggert and Noah Misch.
6132 2006-04-12 Eric Blake <ebb9@byu.net>
6134 * tests/autotest.at (Debugging a failed test): Fix comment.
6136 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6138 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6139 all the changes since 2006-04-07.
6141 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6143 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6144 succeeded, but `ln -s file dir' failed, take care to remove the
6145 leftover target before the next test, to prevent its spurious
6146 failure; also make sure `ln file dir' works before selecting it.
6147 Thanks to Keith Marshall for pointing this out.
6150 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6151 assignments in `at_debug_args', so that we put them correctly
6152 in the `run' script.
6153 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6154 Reported by Eric Blake.
6156 2006-04-11 Eric Blake <ebb9@byu.net>
6158 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6159 top-level tests after micro-suite has been run. Used in...
6160 (Debugging a successful test, Debugging script and environment),
6161 (Debugging a failed test): ...these new tests. The first of these
6163 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6164 macro, split out from...
6165 (AT_INIT): ...here, so that using -d also generates a run script.
6166 Document that -d inhibits top-level logging.
6167 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6168 inhibits top-level logging; debug scripts are created.
6170 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6172 * tests/autotest.at (Empty test, Empty check): New test to check it.
6174 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6177 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6179 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6180 the files if a problem appears. Make the empty *.at files
6181 read-only, too. Proposed by Ralf Wildenhues.
6183 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6185 * config/Makefile.am: Add comment to force updated Makefile.in.
6187 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6188 space only patch to this file, this patch causes the Makefile.in
6189 files that include freeze.mk to be updated, and thus have a
6190 newer time stamp again, which in turn makes a pristine CVS
6191 checkout have correct time stamps.
6193 * Makefile.maint (cvs-sv): New macro, to be used..
6194 (config.guess-url_prefix, config.sub-url_prefix)
6195 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6196 point to CVS text checkout of Gnulib files.
6197 (copyright-check): Bump current year.
6198 (announcement): Do not hard-wire `./announce-gen'.
6199 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6201 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6203 (wget_files): Update config.guess, config.sub, texinfo.tex by
6204 `wget-update', now that their URLs work again.
6206 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6208 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6209 Problem noted by Paul D. Smith.
6211 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6213 * doc/autoconf.texi: Remove unused words from word list.
6214 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6215 .x-sc_trailing_space: New files.
6217 * doc/standards.texi: Sync from gnulib.
6219 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6220 `LIBOBJDIR' as experimental.
6222 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6223 with a target directory; it's internally implemented as `cp'
6224 anyway, but since Autoconf advertises the possibility to use
6225 a target directory when LN_S is `ln -s', we need to find out.
6226 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6227 analyzed by Keith Marshall <keith.marshall@total.com>.
6231 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6233 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6234 confdefs.h as-is. In general, if it has backslash-newline or the
6235 like, then it doesn't work either to sort or to remove empty
6238 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6240 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6242 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6244 * lib/autom4te.in (Automake-preselections): Preselect
6247 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6249 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6250 apostrophe within a single-quoted string, as this is the usual
6251 tradition and is easier to read than '"'"'. Don't rely on the
6252 shell treating "$/" like '$/'. Use a more-consistent indenting
6255 2006-04-09 Eric Blake <ebb9@byu.net>
6257 * tests/autotest.at (Backquote command substitution),
6258 (Multiline backquote command substitution): Remove mistaken
6259 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6261 (Parenthetical command substitution, Multiline parenthetical
6262 command substitution): here.
6264 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6266 Import macros from gnulib (often changing their name).
6268 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6269 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

6342 _AS_DETECT_BETTER_SHELL:
6344 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

6373 AS_MKDIR_P exits the script on failure.
6374 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6376 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6395 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6397 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6398 whether `set' quotes correctly: redirect stderr of the tested
6399 `set', and use a subshell, for Ultrix; use `sed' instead of
6400 `grep' for zsh `set' which may write binary output; match only
6401 at the beginning of a line, to avoid false positives.
6402 In order to avoid false positives by unrelated variables with
6403 multiline content, put the dump algorithm in a subshell and
6404 unset all variables containing newlines (except some which are
6405 special to the shell). Warn about cache variables that are

6451 ac_config_<foo>s again, sometimes normalized, sometimes not.
6452 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6453 (AC_CONFIG_COMMANDS): Do not do so here.
6454 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6455 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6456 2005-07-25 rewrite. Noticed by Noah Misch.
6458 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6459 _AC_PRESERVE_HELP_ORDER, ...

6466 for --help from Cygnus `configure.'
6468 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6518 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6520 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6521 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

6525 (exclude_list): Exclude empty macros.
6526 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

6609 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6610 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6611 ac_file to the name of the default output file and call
6612 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6613 initial `rm' of the candidate files...
6614 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6615 the same list in subsequent `rm' calls, and for the temporary

6620 no longer needed) by libtool. Make it a cache check.

6622 copied here by mistake.

6699 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6700 switch all of them on and of when necessary. Fixes the bug when

7398 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7399 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7400 by the function rather than ignoring it.
7401 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7402 comparing its address. Intel's interprocedural optimization was
7403 outsmarting the old heuristic. Problem reported by

7415 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7417 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7418 before removing it (chmod -R u+rwx); there are three instances of this.

7421 Stepan Kasal <kasal@ucw.cz>
7423 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7424 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7425 make its content writable before removing it. Remove an errorneous
7426 comment from the end, where the logs of the failed tests are copied
7427 to the main log file.
7429 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7431 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

7436 problems if the testsuite were running too fast.
7438 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7440 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7441 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7442 (which belong to Xt, not X itself). See Debian bug 327655.
7443 * NEWS: Mention this.
7445 2005-09-07 Stepan Kasal <kasal@ucw.cz>

7451 * config/move-if-change: Don't output "$2 is unchanged";
7452 suggested by Ben Elliston. Handle weird characters correctly.
7454 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7456 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7457 calls, so that the final expansion of this macro is shorter.
7458 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7459 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7460 the cleanup there. Use AS_VAR_* macros, to be more general.
7461 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7463 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7465 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7483 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7485 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7486 in the example. Reported by Bruno Haible.
7487 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7488 "if $undefined_var;" succeeds with my shell.
7490 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7491 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7492 but change the m4_divert_text to m4_divert_once.
7494 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7496 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7497 Work around bug in Solaris /usr/xpg4/bin/awk.
7498 The bug is present in at least Solaris 8 through 10.
7500 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7502 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7503 some evil values and relying on the fact that $* concatenates the
7504 parameters by the first character from IFS.
7506 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7507 Stepan Kasal <kasal@ucw.cz>

7510 first header appears, define AH_HEADER.
7511 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7512 Update limitations about when to call AC_CONFIG_HEADERS.
7513 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7514 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7515 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7516 ``Configuration Actions''; fix their index entries.
7518 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7519 options correctly. Process N-M as M-N if M is smaller than N.
7520 Process ranges correctly so that N-N will run only N.
7521 Sort and uniquify the tests that will be run. If there is more
7522 than one test, reinsert the banners for the tests.
7523 * tests/autotest.at (Keywords): Unmark XFAIL.
7525 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7527 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7528 before passing the macro name to AH_TEMPLATE.
7530 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7531 now opens log after option processing; in particular, --version
7532 and --help do not touch config.log.

7545 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7548 * doc/autoconf.texi (Defining Symbols, Changed Results):
7549 Prepend to LIBS, not append, in examples.
7551 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7553 When building in place, set srcdir="."; suggested by Tim Van Holder.
7555 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7556 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7557 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7558 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7559 does not mean "no --srcdir option".
7561 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7563 * tests/autoscan.at (autoscan): New file.
7564 * tests/suite.at: Use it.
7565 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7566 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7568 * tests/autotest.at (Keywords): Test keywords combinations.
7570 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7572 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7573 add "2>&1"; gzip 1.2.4 prints help on stderr.
7575 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7577 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7578 was pushdef'ed twice while popped only once. Push it only once.
7579 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7581 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7583 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7588 * Makefile.maint: Update from Bison.
7590 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7591 "<tab>" in comment, so that the point is understandable.
7593 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7595 Rewrite substantial part of lib/autoconf/status.m4.
7596 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7597 and CONFIG_COMMANDS are not processed in four separate loops.
7598 Instead, there is one main loop. This alows that the common code
7599 is expanded only once, thus config.status (and configure) is smaller.
7601 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7602 the AC_LIST_FILES and cousins macros are no longer used.
7604 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7605 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7606 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7607 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7608 contain the initialization, nor the for loop, nor the associated
7609 commands; all these go to ...
7610 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7611 _AC_OUTPUT_CONFIG_STATUS.
7612 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7613 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7614 (_AC_OUTPUT_FILE): The creation of the sed script ...
7615 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7616 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7617 _AC_OUTPUT_MAIN_LOOP.
7618 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7619 _AC_CONFIG_COMMANDS): Use ...
7620 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7621 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7622 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7623 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7624 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7625 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7627 (_AC_CONFIG_UNIQUE): Update.
7628 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7629 Replaced by this ...
7630 (_AC_LIST_TAGS): ... new common macro.
7631 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7632 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7633 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7634 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7635 this didn't belong to the `config commands' section.
7636 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7637 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7638 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7639 to the `config commands' section either.
7640 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7641 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7643 ... and many changes to the comments nearby.
7645 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7646 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7647 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7648 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7649 (#define header templates): The comment at the top of the generated
7650 header now includes the name(s) of the source file(s).
7652 Several unrelated small changes:
7654 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7655 parameter to AC_DIAGNOSE.
7656 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7657 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages

7758 configure_input, top_builddir, srcdir, etc.
7759 * lib/autotest/general.m4 (AT_INIT): Likewise, for

7852 variable into diagnostic. Make the diagnostic an error, not a warning,
7853 because we really don't support spaces and suchlike in dir names.
7854 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7855 Don't worry about backslashes in srcdir; it can't happen now.

7899 * doc/autoconf.texi:
7900 Don't mention Solaris versions so much, if a
7901 problem is common to all extant versions of Solaris. Say "SunOS
7902 4" instead of "SunOS" for SunOS 4.
7903 (awk): Mention more of the limitations of traditional Awk.

7948 Problem reported by Ralf Menzel.
7950 2005-06-08 Derek Price <derek@ximbiot.com>
7952 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7953 renaming them since they are about to be redefined anyhow.

7994 m4_cdr of one-member list was [[]] (one-member list containing an
7995 empty string) instead of [] (an empty list. Callers were skewed to
7996 match this misbehaviour. As a consequence of this:
7997 - m4_foreach([x], [], [foo]) expanded to `foo', while
7998 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7999 This bug has been fixed:
8001 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8002 expand to an empty string; print error msg if called without
8004 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous

8015 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8016 swallow records with more than 99 fields.
8017 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8018 parse the long line.
8020 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8022 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

8127 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8130 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8132 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8133 argument to m4_foreach. I guess it was necessary in the past,
8134 but I think it's a no-op now.
8136 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8138 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8139 ``cat <<_ACEOF'' commands to one.
8140 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8141 * lib/autoconf/status.m4: On various places, use expr instead of
8143 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8144 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8145 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8147 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8148 the wrong patterns between ``case'' and ``esac.'' The previous
8149 code had false positives.
8151 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8153 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

8201 enough arguments, similarly as in m4_bpatsubsts.
8203 2005-05-12 Stepan Kasal <kasal@ucw.cz>
8205 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
8208 2005-05-11 Stepan Kasal <kasal@ucw.cz>
8210 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
8211 for absolute directory names in one loop.

8213 abbreviations of --version and --debug.
8215 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
8217 * doc/autoconf.texi (Autoconf Language): Be more precise about
8218 quoting rules. Problems noted by Stepan Kasal.
8219 Also, throughout this document, be more careful about white space.
8220 "blank", "white space", and "space" all have different meanings
8221 and we should be careful to say what we mean.
8223 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8225 Fix C++ related problems reported by Werner Lemberg.
8226 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
8227 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
8228 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
8229 avoid problems with C++ and throw.
8230 * tests/compile.at: .cpp, not .cc.
8232 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8234 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8236 * doc/autoconf.texi (Generic Functions): Typos.
8238 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8240 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8241 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8242 set by latest automake.
8244 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8246 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8247 outputs 0 on GNU/Linux these days.
8249 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8251 * doc/autoconf.texi (Autoconf Language): Add more description
8252 about quoting heuristics.
8253 (Limitations of Builtins): Describe "set -" problems.
8255 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8257 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8260 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8261 by AC_DEFINE; it was a mistake.
8262 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8264 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8266 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8268 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8270 * doc/autoconf.texi (External Software): Quadrigraphs are not
8271 processed correctly in AS_HELP_STRING; avoid this in the examples.
8272 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8273 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8274 comment and reduce m4_default([foo], []) to [foo].
8275 (m4_strip): Update the explanation.
8277 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8279 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8280 Remove core.conftest.* too; it's generated by Tru64 5.1.
8281 Problem reported by Jennis Pruett.
8282 * lib/autoconf/functions.m4
8283 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8284 Don't bother to remove core files; AC_RUN_IFELSE should do that
8287 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8289 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8291 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
8293 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
8294 Report from Horst Wente.
8296 2005-04-15 Stepan Kasal <kasal@ucw.cz>

8303 * doc/autoconf.texi (External Software, Package Options): Add
8304 examples showing how to implement --with-* and --enable-* options.
8306 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8308 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8309 as well as configure.in. Problem reported by Gregorio Guidi.
8311 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8313 * doc/autoconf.texi (Particular Functions): Use gnulib's current

8324 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8326 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8327 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8329 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8331 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8332 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8333 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8334 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8335 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8337 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8339 * NEWS: The configure command now warns you if you attempt to use
8340 a directory whose name contains a special character like space,
8342 * doc/autoconf.texi (Installation Directory Variables): Allow
8343 "," in file names. Do not use \@; it's not a portable regexp.
8344 * bin/Makefile.am (edit): Likewise.
8345 * lib/Makefile.am (edit): Likewise.
8346 * tests/Makefile.am (edit): Likewise.
8347 * tests/semantics.at: Likewise.
8348 * tests/torture.at: Likewise.
8349 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8350 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8351 * doc/autoconf.texi (File System Conventions): Warn about
8352 unportable file names.
8353 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8355 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8356 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8357 ac_pwd, and quote srcdir.
8358 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8360 * doc/autoconf.texi: Fix some systematic formatting problems.
8361 ".)" needs a following @: if not at the end of a sentence, and
8362 similarly for "!)". "etc." should be preceded by a comma.
8363 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8365 2005-03-22 Bruno Haible <bruno@clisp.org>
8367 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8368 argument is often called 'build-aux'.
8370 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8372 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8373 macro AC_TRY_LINK is obsolete.
8374 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8377 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8379 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8380 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8381 from a Common Lisp's `cl'.
8382 (AC_PROG_CXX): Behave according to the documentation: don't
8383 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8384 make the variable CCC precious; use `cl.exe', not `cl'.
8386 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8387 Alexandre Duret-Lutz <adl@gnu.org>
8389 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8390 /dev/null, as "configure" shouldn't read stdin, and this insulates
8391 us from problems (e.g., when testing for "cl"). Also, do this
8392 redirection before invoking "hostname" or "uname", and keep the
8393 original input stream available via...
8394 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8395 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8396 bother with "</dev/null" since it's now done at the top of
8398 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8399 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8400 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8401 * doc/autoconf.texi (File Descriptor Macros): New section.
8402 (Printing Messages): Mention it.
8403 * tests/base.at (Input/Output): New test.
8405 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8407 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8408 newline if neither \c nor -n work, as that would output two
8409 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8411 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8413 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8414 This causes that any required macros inside will get before the if.
8415 * doc/autoconf.texi (autom4te.cache): A typo.
8417 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8419 Undo previous change, except keep the change to
8420 lib/autoconf/programs.m4 that replaced grep with shell
8421 pattern-matching. This is because net-snmp configure reads stdin.
8422 Reported by Noah Misch.
8424 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8426 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8427 from /dev/null, as "configure" shouldn't read stdin, and this
8428 insulates us from problems (e.g., when testing for "cl").
8429 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8430 before invoking "hostname" or "uname".
8431 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8432 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8433 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8434 "</dev/null" since it's now done at the top of 'configure'.
8435 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8436 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8437 Also, replace grep with shell pattern-matching, to save a process.
8439 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8441 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8442 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8443 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8446 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8448 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8449 grep -q isn't portable. Improve grep -s explanation.
8450 Problem reported by Dan Manthey.
8452 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8454 * doc/autoconf.texi (Special Shell Variables): Clarify
8455 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8457 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8459 * doc/autoconf.texi: Use @acronym for DJGPP.
8460 Fix some @code's that should have been @env's, and vice versa.
8461 Sort environment variable names.
8462 Mention that shells no longer inherit IFS.
8463 Don't recommend PATH_SEPARATOR=';' so strongly.
8464 Mention that $RANDOM might expand to the empty string.
8465 "symlink" and "soft link" -> "symbolic link".
8466 Improve mktemp description (reported by Bruno Haible).
8468 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8470 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8471 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8473 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8476 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8478 * NEWS: Mention AT_COPYRIGHT.
8480 * tests/local.at (AT_CMP): Use diff directly on input files rather
8483 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8484 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8486 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8487 and Paul Eggert <eggert@cs.ucla.edu>
8489 * tests/autotest.at (Empty test suite): New test.
8490 * tests/torture.at (Substitute and define special characters)
8491 (Substitute a 2000-byte string, Define to a 2000-byte string)
8492 (Substitute a newline, Define a newline): New tests.
8494 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8496 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8497 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8498 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8499 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8500 (Standard regular expressions): New test.
8501 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8502 excess test name quoting.
8503 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8504 CPPFLAGS to `configure' instead of setting it in `configure'.
8506 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8507 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8510 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8511 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8513 * tests/local.at (AT_CMP): New macro.
8514 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8515 (AC_SAVE_STATE): Move environment grep...
8516 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8517 (AT_CONFIG_CMP): New macro.
8518 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8519 * tests/c.at (Extensions): Do not exit early.
8520 * tests/atlocal.in: Inherit $GREP.
8522 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8523 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8525 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8526 (AC_COPYRIGHT): Factor header comment portion out and move into...
8527 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8528 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8529 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8531 * tests/local.at: Add Autoconf test suite copyright notice.
8532 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8534 2005-02-04 Bruno Haible <bruno@clisp.org>

8539 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8541 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8542 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8544 Try not to generated lines of unlimited length, as POSIX places a
8545 2047-byte limit on line length of portable text files.
8546 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8547 Use newline as a separator, not space.

8549 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8552 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8554 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8555 as_func_*. Add test to check whether positional parameters
8556 are restored after function return.
8558 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8560 * doc/autoconf.texi (Special Shell Variables): Mention _,
8561 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8562 if they contain a lower-case letter. The DUALCASE problem was
8563 reported by Ralf Wildenhues.
8565 * bin/autoconf.as: Don't exit with status 0 after write failure
8566 with --help or --version.

8605 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8606 Update the long comment explaining it.
8608 m4_require no longer writes an ``is required by'' line to the
8609 execution stack. It contains only one bit of non-redundant
8610 information: that the macro was required, not called. And even
8611 this bit is useless in most situations: have you ever met a macro
8612 which both calls and requires the same macro?
8614 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8615 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8623 * tests/m4sugar.at (m4_require): Expect output without the
8624 ``is required by'' messages.
8626 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

8662 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8663 Warn about newline stripping in `` and $(). Update Solaris
8665 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8666 X insulates us from future changes to Posix.
8667 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

8692 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8694 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8720 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8721 stored in _m4_divert_diversion or _m4_divert_dump.
8722 (m4_divert_pop): When the parameter is given, compare the symbolic
8723 name with the last diversion pushed on the stack. Previously, the
8724 current diversion was compared with the numeric value of the
8725 diversion given as the parameter.
8726 (m4_require): If the macro hasn't been expanded yet, call ...
8727 (_m4_require_call): this new macro.

8760 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

9034 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9035 "char c = '\200';" rather than "char c = 0x80;" as the
9036 latter doesn't conform to the strict C standard due to
9037 overflow on signed char hosts.
9039 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
9040 to -qlanglvl=ansi. We don't want to disable extensions.
9042 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
9044 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
9045 (Using Autotest, testsuite Scripts, Writing testsuite.at):

9098 2004-11-13 Stepan Kasal <kasal@ucw.cz>
9100 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9101 the $1_found variable, don't test whether the file is executable;
9102 Both things are checked ...
9103 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
9104 the former ``test -f''.

9119 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9120 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9121 variants", "Unix", and some related minor wording fixups.
9123 (Shellology, Special Shell Variables): Document that the Zsh
9124 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

9134 of putenv. Problem reported by Michael Wardle.
9136 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9138 * doc/autoconf.texi (auindex): New macro.
9139 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9140 Problem reported by Stepan Kasal.
9142 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
9144 Fix problems reported by Andreas Buening in:
9145 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
9146 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9148 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9149 readable; it's not true in OS/2-emx.
9151 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9153 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9154 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9155 (trivial change). Problem and patch reported by Andrew Church in:
9156 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9158 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
9160 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

9185 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9186 texinfo.tex for now (done by hand now).
9187 * Makefile.maint (wget_files, cvs_files):
9188 Remove ansi2knr.c; nobody uses it.
9189 (ansi2knr.c-url_prefix): Remove.
9190 (cvs-update): Fix test for failure. I don't know why it ever
9193 * doc/autoconf.texi: Update URLs, some of which went stale.
9194 Use @uref rather than @href.
9196 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9197 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9199 * config/config.guess, config/config.sub, config/elisp-comp,
9200 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9201 doc/fdl.texi, doc/standards.texi: Sync with master copy.

9211 Use "file name" rather than "filename" or "path",
9212 to be consistent with the terminology of the GNU coding standards.
9214 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9216 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9217 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9218 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9219 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9221 More fixes to support spaces in the name of the build directory.
9222 This isn't a complete fix but it's an improvement.
9224 * bin/autoconf.as (autom4te_options): New var.
9225 Use it instead of appending to AUTOM4TE, so that we can allow
9226 spaces in the build directory's absolute name.
9227 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9228 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9229 AT_CHECK_NOESCAPE): Likewise.
9230 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9231 main program): Likewise.
9233 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9235 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

9241 * doc/autoconf.texi (Function Portability): Document isinf and
9242 and isnan. From a suggestion by Kevin Ryde.
9244 * lib/Autom4te/General.pm (END): Return correct exit status even
9245 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9247 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9249 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9250 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9251 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9253 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9255 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9256 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9257 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9258 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9259 * lib/autom4te.in (Automake-preselections): Preselect
9260 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9262 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9264 * lib/autom4te.in (Automake-preselections): Preselect
9265 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9268 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9270 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9272 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9273 Document problem with "`""`" in pdksh POSIX mode.
9275 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9277 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9278 with pdksh, too. Problem reported by Patrick Welche via
9280 * doc/autoconf.texi (Shellology): Note that set -o posix is
9281 useful for pkdsh, too.
9283 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9285 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9286 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9287 Don't fail if ENV or BASH_ENV is readonly.
9288 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9289 etc. are read only. Problem reported by Ludovic Courtes.
9291 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9293 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9294 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9297 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9299 * doc/autoconf.texi (File System Conventions): Warn about
9300 names like "aux". Problem reported by Eric Blake.
9302 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9303 by zero instead of array size, so that we can use any arithmetic
9304 constant expression (instead of requiring an integer constant
9305 expression). This allows us to test expressions like DBL_MAX <
9306 LDBL_MAX, which didn't conform to the C standard using the old
9308 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9309 now that we can do floating-point tests at compile time.
9311 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9313 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9314 and LDBL_EPSILON, as the resulting expression isn't an
9315 integer constant expression and violates the C standard.
9316 Problem reported by Nelson H. F. Beebe. Also, check
9317 for "L" suffix, and check that long double doesn't have
9318 worse range or precision than double, that mixed-mode
9319 arithmetic doesn't generate a diagnostic, that double
9320 constants fit in long double.
9322 2004-06-03 Kevin Ryde <user42@zip.com.au>
9324 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9325 malloc(0) and realloc(NULL,size).
9327 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9330 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9332 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9333 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9336 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9338 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9339 can be rewritten using if-then-else. Suggested by Bruno Haible.
9341 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9343 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9344 Problem reported by Stepan Kasal.
9346 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9348 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9349 change). Patch reported by Ralf Wildenhues in
9350 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9352 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9353 function F exists if the compiler and linker let you compile an
9354 expression like (F != 0). Recent versions of GCC optimize away
9355 the reference to F in that case, since every function address must
9356 be nonzero, so the link succeeds even if F does not exist.
9357 Problem reported by Manu in
9358 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9360 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9361 "Unix". Many uses changed.
9362 (Limitations of Builtins): Explain better why the ! command isn't
9365 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9367 * lib/autom4te.in (Automake-preselections): Preselect
9368 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9370 2004-05-19 Kevin Ryde <user42@zip.com.au>
9372 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9373 referencing AC_FUNC_STRERROR_R.
9375 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9376 note pessimistic assumption when cross compiling.
9378 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9380 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9381 (until 2004) invoked subcommands with sh -e, contra POSIX.
9382 Reported by Kevin Ryde.
9384 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9386 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9387 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9388 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9389 `test -f " /usr/bin/grep"', which _always_ failed.
9390 (AC_PROG_SED): Ditto bogus PATH fix.
9391 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9392 requires that grep correctly supports _multiple_ `-e' options, rather
9393 than stating only that grep should accept `-e'.
9395 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9397 Port to C99, which requires that 'exit' be declared.
9399 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9400 to ensure that stdlib.h is included.
9401 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9402 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9403 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9404 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9405 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9406 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9407 when using 'exit' in a test; C99 requires that 'exit' be declared.
9409 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9411 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9412 now prefers 'grep' implementations that accept -e.
9413 (Limitations of Usual Tools): Describe problems of traditional
9414 egrep and fgrep with long input lines, and of traditional grep
9416 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9417 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9418 All callers changed. Append /usr/xpg4/bin to the PATH, for
9420 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9421 the user with complaints about multiple -e options.
9422 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9423 Define it with AC_PROG_GREP.
9424 * configure.ac (AC_PROG_GREP): Add.
9425 * lib/freeze.mk (GREP): New macro.
9427 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9429 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9430 a possible candidate only after all others fail, rather than
9431 consulting it first. This improves backward compatibility by
9432 better reflecting the way shell selection occurred in previous
9433 versions of Autoconf, and should help to avoid triggering latent
9434 problems in other packages, such as the one in Automake where zsh
9435 is not handled robustly:
9436 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9437 Although it is not Autoconf's responsibility to work around
9438 problems in Automake, it nevertheless makes sense to avoid
9439 introducing unnecessary incompatibilites.
9441 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9442 Gary V. Vaughan <gary@gnu.org>
9444 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9445 how deeply nested we are when a suitable tool is found, set the
9446 ac_path_TOOL_found flag.
9447 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9448 nested we are in this macro. Break out of all 3 nested loops if
9449 ac_path_TOOL_found is set.
9451 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9453 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9454 of the _AS_PATH_WALK loop too if GNU flavor is found.
9456 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9458 * doc/autoconf.texi (Limitations of Make): Update documentation
9459 for `$<'. New entry `Long lines', based on a report from Simon
9460 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9461 paragraph about DJGPP, based on a mail from Richard Dawe.
9463 2004-04-20 Paul Eggert <eggert@twinsun.com>
9465 * tests/c.at (C keywords): Don't assume that GCC supports
9466 "restrict" and "inline", as sufficiently-old GCC versions do not
9467 (also, GCC configured to be in pedantic C89 mode does not).
9468 Problem reported by Sumit Pandya in:
9469 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9471 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9472 consider -g to work if it generates warnings when plain compiles
9473 don't. Problem reported by Braden McDaniel in:
9474 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9476 * doc/autoconf.texi (Slashes): New section, to document a problem
9477 reported by Jim Meyering in:
9478 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9480 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9481 linker output files before linking, to work around IRIX 6 linker bug.
9482 Problem reported by Rainer Orth in:
9483 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9485 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9487 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9488 best tool so far counter rely on the tool path variable name to
9489 avoid checks for one tool being affected by the results of running
9490 the length check on a previous tool.
9492 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional

9632 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9633 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.

9711 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9712 2003 (except 1997) to the list of copyright years. This undoes
9713 the 2003-05-22 change, which removed the older years from the list.

9727 _AC_PROG_GREP, and AC_PROG_SED.

9760 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9761 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9762 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9763 not <inttypes.h>. Problem reported by Tim Mooney in

9765 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9768 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9769 otherwise "make check" fails because it forbids cmp (I guess
9770 because cmp treats files as binary on DOS-like systems).

9785 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since

9793 AS_MKDIR_P succeeds if the destination is a symbolic link
9794 to an existing directory.
9795 (Limitations of Usual Tools): Note that mkdir -p might not
9796 succeed on symlinks to directories.

9816 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9817 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9818 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9819 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9820 AC_COMPILE_IFELSE, since we now assume our caller invokes
9821 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9822 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9823 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9824 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9826 2004-01-07 Paul Eggert <eggert@twinsun.com>
9828 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9829 `"'...'"`, as it's confusing (and I suspect it may not work on
9830 some platforms). The code was incorrect anyway, as it assumed
9831 that \$ evaluated to itself in that context. Reported by
9832 Alexandre Duret-Lutz.
9834 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

9866 Bug reported by David Relson in
9867 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9869 * Makefile.am (autom4te-update):

9887 -c -o might not work. From a suggestion by Kevin Ryde.
9888 (C Compiler, Generating Sources, Limitations
9889 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9890 Don't put '-o' after non-options, as POSIX doesn't allow this.

9902 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9904 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9905 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

10009 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10010 than $target since the latter is not usual, add guidelines on when to

10192 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10193 -mGLOB_options_string stuff for Intel ifc, which can cause

10218 cache variable instead of $G77 to decide whether to include -O2,

10229 arguments so that it can be used with syntax identical to

10231 remove/deprecate the DIALECT optional argument in the future if it
10232 proves troublesome.
10233 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10234 non-freeform-supporting compilers. Document freeform flags.
10236 2003-10-03 Akim Demaille <akim@epita.fr>

10305 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10306 directory for AC_CONFIG_COMMANDS' first argument exists.
10307 This makes valid the invocation of _AC_SRCPATH that follows.
10308 Reported by Eric Sunshine.

10332 The test suite are sometimes assigning timings incorrectly.
10333 Reported by Henk Krus.
10334 Diagnosed by Nicolas Joly.
10336 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10338 Instead of making AT_help a sequence of assignments to grow
10339 $at_help_all, just make AT_help_all be the growing contents of
10340 $at_help_all, and make a single assignment in...
10342 (at_times_skip): Flip the meaning and rename as...
10343 (at_times_p): this.

10354 (ifnames): chmod -w.
10355 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10356 executables, not bin/ executables! Otherwise all the magic needed
10357 to find non installed files is turned off. This caused a failure
10358 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10359 as found in its environment (sent by tests/autoreconf): pointing
10360 to bin/autom4te that could not find its files.
10361 * tests/mktests.sh: Force the replacement of generated files, for
10362 the sake of "mv" program that are interactive when overwriting a

10374 Trivial change to support GCC's configuration procedure.

10415 and AC_FC_FREEFORM.

10453 2003-09-04 Akim Demaille <akim@epita.fr>
10455 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10457 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10459 Add support for newer Fortran dialects. The F77 interface is
10460 unchanged, and continues to support Fortran 77. New FC macros
10461 correspond to all the old F77 macros, with output variables FC,
10462 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10463 available dialect, but older dialects can be specified. There are
10464 new macros AC_FC_SRCEXT to set the source extension, and
10465 AC_FC_FREEFORM to accept free-form source files.
10467 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10469 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

10588 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10589 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10591 2003-08-21 Akim Demaille <akim@epita.fr>
10593 First stab at preserving warnings between calls to autom4te,
10594 including when the cache is used.
10596 There are still several issues: (i) there are too many runs of m4
10597 (one for include, one for warnings, and some more), (ii) warnings
10598 spreading on several lines are not handled gracefully, (iii) the
10599 code meant to have the call stack display for errors does not work
10600 (its handling should move from m4 to autom4te).
10602 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10604 (@preselect): Add m4_warn.
10605 ($exit_status): Remove, use $exit_code.
10606 ($help): Use Autom4te::ChannelDefs::usage.
10607 (&handle_m4): No longer define the m4_warnings.
10608 At each run, extract and report the warnings.
10609 Always cache the result, including if the exit status is on
10610 failure, since if nothing changes, we should result in the same
10611 failure, hence we can use the cache.
10612 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10613 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10615 (m4_warn): Redefine as a do-nothing: it is its invocation that
10616 matters, as warnings are now reported via traces.
10617 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10618 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10619 the latter reveals calls to the former.
10623 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10625 2003-08-21 Akim Demaille <akim@epita.fr>

10635 (&parse_warnings): Accept a list of warning requests.
10636 (&usage): Return a string, not a side effect.
10637 (cross): New warning category.

10641 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10642 (&require_configure_ac): Accept an optional directory argument.
10643 ($configure_ac): Remove.
10644 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10645 (&catfile): Remove.
10646 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10647 * bin/autoscan.in: Adjust.
10649 2003-08-20 Akim Demaille <akim@epita.fr>
10651 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10652 Reported by Alexandre Duret-Lutz.
10654 2003-08-20 Akim Demaille <akim@epita.fr>
10656 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10657 * bin/autom4te: Adjust.
10658 In particular, be Autoconf tools are really silent when properly
10659 working, bind the verbosity of the 'note' channel to $verbose.
10660 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10661 (&xsystem, &contents): Remove, since they are exported by...
10662 * lib/Autom4te/FileUtils.pm: this.

10665 * lib/Autom4te/FileUtils.pm: here.

10724 shorter column three. Add DESCRIPTION to log file content.

10782 2003-06-23 Akim Demaille <akim@epita.fr>
10784 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10785 not all of them. This fixes 1. the fact that when testing
10786 Autoconf there are many many config.log, 2. the incorrect use of
10787 top_srcdir to find config.log.
10788 Don't mix the detailed output of failed test with the summary of
10789 failures. Rather, append detailed log afterwards.
10791 2003-06-23 Akim Demaille <akim@epita.fr>
10793 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10908 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10909 Remove `#include <stdlib.h>' from the list; we should never
10910 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10911 resulting namespace pollution would cause other tests to fail.
10912 Configure scripts run with some older versions of g++ and HP's
10913 aCC would fail due to such an #include. Problems reported by
10914 Matthew Mueller in <http://bugs.debian.org/120704> and by
10916 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10917 In the test, use the test declaration before including <stdlib.h>,

10928 in testsuite.dir/NNN/testsuite.log, and append them to
10929 testsuite.log instead of re-running the test verbosely.
10931 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10932 file descriptor, write 0 to at_status_file instead of setting
10933 at_status=0, initialize some new variables (at_status_file,
10934 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10935 to rerun the tests, instead append the at_group_log to the
10936 at_suite_log when a test fails.
10937 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10938 with the AS_MESSAGE_LOG_FD redirected to stdout.
10939 (AT_CLEANUP): save the output status in $at_status_file
10940 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10941 its original place.
10942 (AT_CHECK): since tests are run with a redirected stdout,
10943 and used to be re-run in verbose mode, turn some $at_verbose
10944 into echo, and don't redirect the output of testing stdout
10947 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10948 the name of the debugging directory and information about

11068 2003-05-06 Akim Demaille <akim@epita.fr>
11070 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11071 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11072 by aclocal.m4 is changed it might require the importing of another
11073 m4 extension file, i.e., aclocal must be run.
11075 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11076 (&parse_args): Use --force with aclocal if required and supported.

11090 2003-04-29 Derek Price <derek@ximbiot.com>
11092 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11093 seperator with m4_append_uniq(). It doesn't work.
11094 (AT_CLEANUP): Add `;' to end of at_help_all.
11095 (AT_INIT): Allow --keywords to be specified more than once. When
11096 grepping $at_help_all for keywords, use the field and keyword

11103 align better with others. I also made some of the individual
11104 entries on one line, for brevity and to make it easier for me to

11328 (and earlier versions) have a <limits.h> that declares
11329 gettimeofday and many other functions.

11346 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11347 defined, to support freestanding compilers. This should fix the
11348 bug reported by Momchil Velkov in
11349 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11351 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11352 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11387 * Makefile.maint: Sync with Bison, i.e.:
11388 (po-check): Scan .l and .y files instead of the
11389 .c and the .h files that they generate. This fixes the bug
11390 reported by Tim Van Holder in:
11391 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11392 Look for N_ as well as for _. Try to avoid matching #define for

11451 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11453 We _have_ to stop using the old compatibility scheme that tried to
11454 avoid useless backslashes because Libtool 1.4.3 contains a
11455 AC_DEFINE([error_t], [int],
11456 [Define to a type to use for \`error_t' if it is not
11457 otherwise available.])
11458 We _have_ to quote the single quote and backslashes with \. The
11459 old compatibility scheme saw that ` was backslashed, and therefore
11460 did not quote the single quote. Hence before this patch, Autoconf
11461 was not compatible with Libtool.

11916 aclocal invocation, as Gettext macros might not be visible to
11918 Instead of blindly running autopoint, scan configure.ac (not the
11919 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11920 Reported by Paul D. Smith.
11922 2002-10-08 Paul Eggert <eggert@twinsun.com>
11924 Work around problems found when POSIXLY_CORRECT=1 is set.
11925 None of this seems to have anything to do with POSIX, really,
11926 but it's how Perl getopt works.
11927 * bin/autom4te.in (parse_args): Configure GetOpt with
11929 * doc/autoconf.texi (Invoking autom4te):
11930 --warning -> --warnings.
11931 * lib/autom4te.in: --warning -> --warnings.
11933 2002-09-28 Akim Demaille <akim@epita.fr>
11935 * doc/autoconf.texi (autom4te.cache): New section.
11937 2002-09-28 Akim Demaille <akim@epita.fr>
11939 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
11940 (Automake-preselections): Update.
11941 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
11943 2002-09-28 Akim Demaille <akim@epita.fr>
11945 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
11946 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
11947 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11948 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11950 2002-09-28 Akim Demaille <akim@epita.fr>
11952 * tests/torture.at (Configuring subdirectories): Be robust to
11953 users who use config.site to require for a cache: in this case,
11954 the two last configure runs, using two different sets of
11955 arguments, trigger a legitimate error.
11957 2002-09-28 Akim Demaille <akim@epita.fr>
11959 * tests/m4sh.at (Functions Support, Functions and return Support):
11962 2002-09-28 Akim Demaille <akim@epita.fr>
11964 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11965 autoheader are Perl programs.
11966 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11967 (autom4te): Specify that the sources are in the $srcdir.
11968 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11970 2002-09-28 Akim Demaille <akim@epita.fr>

11973 (tm_zone): Move their rules to...
11974 * lib/autoconf/types.m4: here, using AN_ macros.
11975 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11976 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11977 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11978 * lib/autoconf/programs.m4: here.

11988 that were listed in the original autoscan.list.
11989 * lib/autoconf/headers.m4: Similarly with headers.
11990 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11991 (.m4.m4f): Don't pass --prepend-include, since that's done by
11992 tests/autom4te itself.
11993 * lib/autoscan/Makefile.am: Include freeze.mk.
11994 (autoscan.list): New target --this file is no longer a source.
11995 (autoscan.pre): New file.
11997 2002-09-28 Akim Demaille <akim@epita.fr>
11999 * bin/autoscan.in (@kinds): Make them singular.
12001 (&init_tables): When --debug, report the list of rules to ease
12002 tracking changes in autoscan.list.
12003 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12005 2002-09-28 Akim Demaille <akim@epita.fr>
12007 * lib/autoscan/functions, lib/autoscan/headers,
12008 * lib/autoscan/identifiers, lib/autoscan/makevars,
12009 * lib/autoscan/programs: Merge into...
12010 * lib/autoscan/autoscan.list: this.
12011 * bin/autoscan.in (&init_tables): Adjust.
12013 2002-09-28 Akim Demaille <akim@epita.fr>
12015 * lib/autoscan/functions, lib/autoscan/headers,
12016 * lib/autoscan/identifiers, lib/autoscan/makevars,
12017 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12018 `functions' line is now prefixed with `function:'.
12019 * bin/autoscan.in (&init_tables): Adjust.
12021 2002-09-28 Akim Demaille <akim@epita.fr>
12023 From now on, autoscan files must always map a macro name to a
12024 word: there is no `default' macro for autoscan.
12026 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12028 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12031 2002-09-28 Akim Demaille <akim@epita.fr>
12033 * bin/autoscan.in (%c_keywords): Remove.
12034 (&used): Keep only track of the words we might be interested in.
12035 (&output_kind): It is no longer needed to look for non active
12038 2002-09-27 Akim Demaille <akim@epita.fr>
12040 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12041 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12042 * lib/autoscan/functions: Adjust.
12043 * doc/autoconf.texi (Particular Functions): Adjust.
12045 2002-09-27 Akim Demaille <akim@epita.fr>
12047 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12049 Thanks to Bill Moseley and Paul Eggert.
12050 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12051 the tmpdir must be created.
12052 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12053 dir be in the build tree, instead of $TMPDIR.
12055 2002-09-27 Akim Demaille <akim@epita.fr>
12057 * bin/autoscan.in: Improve the comments.
12058 (&parse_args): Drop obsolete undocumented options.
12059 (&output_kind): Output warnings.
12060 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
12061 (getwd): Trigger a warning.
12063 2002-09-26 Akim Demaille <akim@epita.fr>
12065 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12066 Reported by Ralf Corsepius.
12067 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12069 2002-09-26 Akim Demaille <akim@epita.fr>
12071 Single suffix rules and seperated dependencies are not portable.
12073 * doc/autoconf.texi (Installation Directory Variables): Update.
12074 (Limitations of Make): Some about `Single Suffix Rules and
12075 Separated Dependencies'.
12076 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12077 (ifnames, autoscan, autom4te): Un-factor into several rules.
12079 2002-09-25 Paul Eggert <eggert@twinsun.com>
12081 * BUGS (Interoperability bugs): New section. Mention libtool
12082 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12084 2002-09-24 Paul Eggert <eggert@twinsun.com>
12086 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12087 make handles suffix-rules differently from GNU make.
12089 * bin/Makefile.am (SUFFIXES, .in): Remove.
12090 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12091 Move the body of the old .in rule here.
12093 2002-09-16 Akim Demaille <akim@epita.fr>
12095 i960 compilers create `b.out' files by default.
12096 Reported by Ralf Corsepius.
12098 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12099 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12101 2002-09-13 Paul Eggert <eggert@twinsun.com>
12103 * doc/autoconf.texi (Particular Headers): Remove obsolete
12104 reference to `struct timezone' in the description of
12107 2002-09-13 Akim Demaille <akim@epita.fr>
12111 * config/config.sub, config/config.guess: Update.
12112 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12113 * Makefile.am: Adjust.
12115 2002-09-13 Akim Demaille <akim@epita.fr>
12117 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12118 reading config.log when the compiler is rejected.
12119 Suggested by Guido Draheim.
12121 2002-09-13 Akim Demaille <akim@epita.fr>
12123 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12124 (chdir_init) might hang when stat'ing mounted directories.
12125 Reported by Vance Shipley.
12127 2002-09-12 Akim Demaille <akim@epita.fr>
12129 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12132 2002-09-12 Akim Demaille <akim@epita.fr>
12134 * doc/autoconf.texi (Defining Symbols): Present two different
12135 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12136 difference between 1 argument calls, and 2-3 argument calls.
12138 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12140 * doc/autoconf.texi: Review grammar and punctuation.
12142 2002-09-11 Paul Eggert <eggert@twinsun.com>
12144 * doc/autoconf.texi: Fix minor formatting, spelling, and
12146 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12147 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12150 2002-09-11 Akim Demaille <akim@epita.fr>
12152 * doc/autoconf.texi (Questions): Rename as...
12154 (Defining Directories): New.
12156 2002-09-09 Akim Demaille <akim@epita.fr>
12158 * doc/autoconf.texi (Making testsuite Scripts): Update.
12159 Suggested by Nishio Futoshi.
12161 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12163 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12164 plain `@' is wanted.
12166 2002-09-09 Akim Demaille <akim@epita.fr>
12168 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12169 `duplicates', since the algorithm was too naive and could keep
12170 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12171 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12172 Reported by Ralf Corsepius.
12173 * tests/torture.at (Configuring subdirectories): Exercise these
12176 2002-09-09 Akim Demaille <akim@epita.fr>
12178 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12179 looking for a replacement file.
12180 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12181 directory is relative.
12182 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12183 directory definition.
12184 Reported by Andreas Schwab and Jim Meyering.
12186 2002-09-06 Akim Demaille <akim@epita.fr>
12188 * doc/autoconf.texi (Setting Output Variables): Clarify what
12189 precious variables are.
12190 Suggested by Pontus Skoeld.
12192 2002-09-05 Akim Demaille <akim@epita.fr>
12194 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12195 (ifnames, autoscan, autom4te): Since we don't only depend on
12196 configure.ac variables (such as VERSION etc.), but also on prefix
12197 and so forth, depend on Makefile, not configure.ac.
12198 Reported by Alexandre Duret-Lutz.
12199 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12201 2002-09-05 Kevin Ryde <user42@zip.com.au>
12203 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12204 doesn't seem to be confined to ia64, just say "some versions".
12206 2002-09-04 Akim Demaille <akim@epita.fr>
12208 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12210 * Makefile.am (maintainer-clean-local): Remove.
12211 (MAINTAINERCLEANFILES): Remove COPYING.
12213 2002-09-03 Paul Eggert <eggert@twinsun.com>
12215 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12216 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12219 2002-09-03 Akim Demaille <akim@epita.fr>
12221 * configure.ac: Bump to 2.53d.
12222 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12223 as of today, on Automake's team suggestion.
12225 2002-09-03 Akim Demaille <akim@epita.fr>
12229 2002-09-02 Akim Demaille <akim@epita.fr>
12231 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12233 * configure.ac: Disable SITE_MACRO_DIR.
12235 2002-09-02 Jim Meyering <meyering@lucent.com>
12237 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12238 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12239 Also, tweak grammar: s/make sure to/be sure to/.
12241 2002-09-02 Paul Eggert <eggert@twinsun.com>
12243 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12244 directory names are generally preferable to physical names.
12246 2002-09-02 Akim Demaille <akim@epita.fr>
12248 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12249 Reported by Raja R. Harinath.
12250 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12251 * bin/autoupdate.in: Use error instead of die.
12253 2002-09-01 Paul Eggert <eggert@twinsun.com>
12255 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12256 ordinary shell concatenation rather than echo+tr+sed command that
12257 runs afoul of a long-line-related sed bug in Solaris 8.
12259 * bin/autoheader.in (parse_args): --warning -> --warnings.
12261 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12262 stdout, as traditional "ls" does.
12263 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12264 _AC_COMPILER_EXEEXT_O): Likewise.
12265 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12267 * bin/autoconf.as: Add --prepend-include option. This patch was
12268 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12269 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12271 * bin/autoconf.in, configure: Regenerate.
12273 * doc/autoconf.texi (Special Shell Variables): Mention
12274 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12276 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12277 MAILPATH and set PS1, PS2, PS4 to default values, to work
12278 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12279 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12280 the Autoconf documentation specifies; fall back to "unset" only if
12281 this fails. Use a shell for-loop for this rather than an m4 loop,
12282 to shorten the output script.
12284 2002-08-30 Paul Eggert <eggert@twinsun.com>
12286 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12287 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12288 for the CDPATH problem. Document PWD.
12289 (Limitations of Builtins): Document the problem that "cd $foo" and
12290 "ls $foo" may refer to different directories in shells conforming
12291 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12292 example, since the old example is now out of date.
12294 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12295 FOO" and "ls FOO" talk about different directories; this catches
12296 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12299 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12300 of rolling our own unset.
12301 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12302 in practice we needn't worry about CDPATH if unset doesn't work.
12304 * Makefile.in, aclocal.m4, bin/Makefile.in,
12305 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12306 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12307 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12308 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12309 tests/Makefile.in: Regenerate with Automake 1.6.3.
12311 * config/config.guess, config/config.sub, config/mkinstalldirs:
12314 * configure: Regenerate with self.
12316 2002-08-30 Kevin Ryde <user42@zip.com.au>
12318 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12321 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12323 * bin/autom4te.in (Request::load): Correctly test for "do" read
12326 2002-08-29 Akim Demaille <akim@epita.fr>
12328 * lib/Autom4te/General.pm (&xqx): New.
12329 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12330 hand, which is not portable.
12332 * bin/autom4te.in: Use them.
12333 Use &error instead of die.
12334 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12337 2002-08-17 Paul Eggert <eggert@twinsun.com>
12339 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12340 default list of compilers to try, since it was long ago superseded
12341 by the ksh fc builtin. Suggested by Steven G. Johnson.
12343 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12345 * doc/autoconf.texi (Invoking autom4te): End the option table,
12346 fixing a bug introduced by the previous patch.
12347 (Limitations of Make): Add a 'target lookup' subentry in the
12348 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12350 2002-07-29 Mark D. Roth <roth@feep.net>
12352 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12353 options and use $AUTOM4TE_PATH.
12354 * doc/autoconf.texi: Remove documentation of autom4te
12355 --include-envvar and --site-macro-subdir options and document
12356 use of $AUTOM4TE_PATH.
12357 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12358 arguments from each language section.
12360 2002-07-29 Paul Eggert <eggert@twinsun.com>
12362 * doc/install.texi: Include copyright symbol in copyright notice.
12364 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12366 (AM_MAKEINFOFLAGS): New macro.
12367 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12368 * Makefile.am (INSTALL): Use the new macros.
12369 Use -o rather than --output, since "missing" does not grok --output.
12371 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12373 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12374 comments do not always work. Never trust the exit status of
12377 2002-07-24 Kevin Ryde <user42@zip.com.au>
12379 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12380 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12382 2002-07-23 Paul Eggert <eggert@twinsun.com>
12384 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12385 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12386 apparently treats PATH="nonexistent" as if it contained ".".
12387 Bug reported by Stefan `Sec' Zehl.
12389 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12391 * doc/autoconf.texi (Limitations of Make): Mention the special
12392 handling of the obj/ directory by BSD make.
12394 2002-07-20 Kevin Ryde <user42@zip.com.au>
12396 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
12399 2002-07-19 Akim Demaille <akim@epita.fr>
12401 * doc/autoconf.texi (Function Portability): `exit'.

12657 This improves on an earlier suggestion by H. Peter Anvin.
12659 2002-05-16 Paul Eggert <eggert@twinsun.com>
12661 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12662 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12663 Both macros now accept an optional source-dir arg.
12664 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12666 * NEWS: Document this.
12667 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12669 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12670 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12671 not for GNU extensions; this undoes part of the 2000-11-03 change,
12672 reverting to 2.13-compatible behavior.

12680 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12681 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12682 and it causes a 'test' syntax error if it fails.
12683 Bug reported by Stephen Gildea.
12685 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12686 If prototypes are supported, use them to check this at compile-time,
12687 instead of trying to check it at run-time. If we must do a run-time
12688 check, assume that setvbuf is standard when cross-compiling, as
12689 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12690 Bug reported by Paul D. Smith.
12692 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12693 argument specifying location of getloadavg.c. This removes a
12694 FIXME. This idea was taken from Jim Meyering's implementation in
12696 * doc/autoconf.texi (Particular Functions): Document this.
12697 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12698 that's what the code does; this fixes a bug reported by

12703 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12704 autopoint instead of gettextize.
12705 ($uses_alocal): Rename as...
12706 ($uses_aclocal): this.
12707 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12708 Suggested by Bruno Haible.
12710 2002-05-03 Akim Demaille <akim@epita.fr>
12712 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12714 2002-04-29 Paul Eggert <eggert@twinsun.com>
12716 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12717 files to be 1 second older; just set them to be the same time.
12718 Also, sleep 1 second after the first aclocal, to work around
12719 problems with sub-second time stamps on the input files.
12721 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12723 * doc/autoconf.texi: Mention "set -e -x" lossage
12724 under node "Limitations of Builtins".

12730 From Christian Cornelssen.
12732 2002-04-29 Akim Demaille <akim@epita.fr>
12734 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12735 of lack of $LINENO support, then the test will compare the $LINENO
12736 in testsuite vs. the lineno in the test file. This is wrong, of
12738 Be sure to protect it.
12739 Reported by Patrick Welche.
12741 2002-04-25 Akim Demaille <akim@epita.fr>
12743 * doc/autoconf.texi (Obsolete Macros): Typo.
12744 Reported by Vladimir Volovich.
12746 2002-04-25 Akim Demaille <akim@epita.fr>
12748 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12749 than some of the input files, hence, on the second run of aclocal,
12750 if some of its input are younger, make them older.
12751 Suggested by Paul Eggert.
12753 2002-04-25 Akim Demaille <akim@epita.fr>
12755 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12761 and ac_subst_vars be sh variables containing the list of
12762 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12764 (_AC_INIT_PREPARE): Use them to log them.
12765 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12766 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12767 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12768 _AC_SUBST_FILES and _AC_SUBST_VARS.
12769 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12771 2002-04-24 Akim Demaille <akim@epita.fr>
12773 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12774 autoheader, so that automake does not complain about a missing
12775 config.h.in that was to be created.
12777 2002-04-23 Akim Demaille <akim@epita.fr>

12883 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12884 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12886 Adjust Autoconf and Autotest.
12888 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12889 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12890 * lib/autotest/general.m4 (AT_INIT): Likewise.
12891 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12892 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12895 Use this M4sh to generate Autoconf's shell scripts.
12897 * tests/wrapsh.as: New, precursor of wrapsh.in.
12898 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12899 on Autotest and M4sh.
12900 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12901 (wrapsh.in): New target.
12902 * bin/autoconf.as: New, precursor of autoconf.in.
12903 (autoconf.in): New target.
12905 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

12908 with indented comments in rules.

12923 directories when descending in a SUBDIRS.
12924 Reported by Ezra Peisach.
12926 2002-04-04 Andreas Schwab <schwab@suse.de>
12928 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12929 contains no literal separators.
12931 2002-04-03 Akim Demaille <akim@epita.fr>
12933 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12934 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12935 Use dnl, not the KILL diversion.
12937 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12938 (AC_CONFIG_LINKS): here.
12940 Don't use the KILL diversion, as it kills spurious output, which
12941 results in failures being hidden.
12942 Use m4_defn where appropriate.
12943 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12944 after the second argument.
12946 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12947 syntax, as it is provided by M4sugar.
12948 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12950 2002-04-03 Andreas Schwab <schwab@suse.de>
12952 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12953 expanded if $# <= 2.
12955 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12958 2002-04-03 Akim Demaille <akim@epita.fr>

12964 (_AC_COMPILER_OBJEXT): Use them.
12965 Fixes Debian #138666.
12967 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12969 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12971 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12972 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12973 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12974 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12975 (AC_C_CONST): Same.
12976 (AC_C_INLINE): Same.
12977 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12978 * doc/autoconf.texi, NEWS: Document.

12985 _AS_MKDIR_P_PREPARE.
12987 2002-03-28 Kevin Ryde <user42@zip.com.au>
12989 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12990 to avoid versions of HP C which don't allow that.
12992 2002-03-27 Paul Eggert <eggert@twinsun.com>
12994 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12995 (AS_SHELL_SANITIZE): Invoke it.
12996 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

13000 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13002 2002-03-26 Akim Demaille <akim@epita.fr>
13004 * doc/autoconf.texi (Introduction): The GNATS base moved.
13006 2002-03-25 Paul Eggert <eggert@twinsun.com>
13008 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13009 as POSIX requires, as it doesn't work with Zsh.
13010 * doc/autoconf.texi (Assignments): Document the problem.
13012 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13014 * doc/autoconf.texi (Limitations of Make): Mention more issue
13015 about VPATH, overriding of macros in sub-makes, and handling of
13018 2002-03-21 Paul Eggert <eggert@twinsun.com>
13020 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13021 problem with here-document buffer boundaries.
13023 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13024 when reinvoking the shell, to work around problems with installers
13025 who put strange things like "cd" commands in their environments.
13027 2002-03-19 Akim Demaille <akim@epita.fr>
13029 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

13034 * bin/autoscan.in (scan_file): Specify the location in `&used'
13038 2002-03-19 Akim Demaille <akim@epita.fr>

13043 2002-03-19 Akim Demaille <akim@epita.fr>
13045 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

13049 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13050 (Limitations of Usual Tools): Add mkdir section.
13052 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13053 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13054 back on AS_DIRNAME to compute prefixes otherwise; this is
13055 roughly what mkinstalldirs does. That way, we need not have
13056 our own filename disassembler. The old disassembler did not
13057 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13059 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13060 Create at_test_all by a series of assignments,
13061 not by a single assignment of a long string. The latter causes ksh
13062 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13063 presumably because of a buffer overrun.
13065 2002-03-14 Paul Eggert <eggert@twinsun.com>
13067 * lib/autotest/general.m4 (at_times_skip):
13068 Renamed from at_times. Now a boolean.
13069 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13070 says 'times: not found'.
13072 2002-03-14 Akim Demaille <akim@epita.fr>
13074 * bin/autoreconf.in (&study_gettextize): New.
13075 (&autoreconf): Handle newest gettextize.
13076 Rerun aclocal if needed.
13077 Suggested by Andreas Schwab.
13079 2002-03-13 Akim Demaille <akim@epita.fr>

13086 Add information about stdint.h and inttypes.h from Paul Eggert.
13088 2002-03-13 Akim Demaille <akim@epita.fr>

13099 2002-03-11 Andreas Schwab <schwab@suse.de>
13101 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13102 does not do it if --with-lispdir is given.
13104 2002-03-08 Akim Demaille <akim@epita.fr>
13108 2002-03-08 Akim Demaille <akim@epita.fr>

13111 subdirectory should exist.
13113 2002-03-08 Akim Demaille <akim@epita.fr>
13115 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13117 2002-03-08 Akim Demaille <akim@epita.fr>
13119 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13120 aliases the actual variables, and modifications of the former
13123 2002-03-08 Akim Demaille <akim@epita.fr>
13125 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13126 because of C-c: have m4 output in tmp files, then mv them.
13128 2002-03-08 Akim Demaille <akim@epita.fr>
13130 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

13149 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13150 * lib/autoconf/general.m4 (AC_INIT): More informative error
13151 message for LIBOBJ.
13153 2002-03-04 Akim Demaille <akim@epita.fr>
13155 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13158 2002-03-04 Akim Demaille <akim@epita.fr>
13160 * doc/autoconf.texi (Transforming Names): Equality between target
13161 and host is irrelevant.
13162 (Specifying Names, Canonicalizing): Remove all references to the
13163 backward compatibility hooks. Rather, collect them all into...
13164 (Hosts and Cross-Compilation): this new section.
13165 * doc/install.texi (System Type): Ditto.
13166 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13167 that `--host' implies cross-compilation.
13169 2002-03-04 Akim Demaille <akim@epita.fr>
13171 * doc/autoconf.texi (Evaluation Macros): New.
13172 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13174 (_m4_foreach): Define the variant with immediate evaluation so
13175 that it contains exactly the items, not an expression which
13176 evaluation is the current item.
13177 (m4_re_string, m4_re_word): Don't over quote them.
13179 2002-03-04 Akim Demaille <akim@epita.fr>
13181 Instead of having stacking `shift's evaluated at the end, let
13182 `foreach' loops immediately evaluate them.
13184 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13185 $*. This is the n-th time I change my mind, but hopefully this is
13188 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13190 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13191 it was only a hack for m4_text_wrap.
13192 (m4_car2): Remove, replaced by...
13194 (_m4_foreach): Adjust.
13195 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13196 m4_bpatsubst for clarification.

13247 Fix Autoconf PR/207:
13248 AC_PREFIX_PROGRAM fails with dashed program names
13250 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13251 variable when looking for the prefix program.
13252 Now it also works for shell variables.

13287 2002-02-05 Akim Demaille <akim@epita.fr>
13289 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13306 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

13309 2002-02-05 Akim Demaille <akim@epita.fr>
13311 * bin/autom4te.in (&parse_args): Implement `frozen files are
13312 optional are the sum of the previous files on the command line'.
13313 Also, pass `--reload-state=' on them, so...
13314 (handle_m4): don't.
13315 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13316 (M4sh): Rely on M4sugar.
13317 (Autotest, M4sh, M4sugar): Use frozen files.
13319 2002-01-31 Akim Demaille <akim@epita.fr>
13321 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

13327 alphanumeric to `-' instead of `_'.
13329 2002-01-30 Akim Demaille <akim@epita.fr>
13331 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one

13333 is now run with GCC only.
13334 * doc/autoconf.texi (Compilers and Preprocessors): New.

13343 2002-01-29 Akim Demaille <akim@epita.fr>
13345 * tests/torture.at (Configuring subdirectories): Use configure.in,
13346 so that aclocal 1.4 works.
13347 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13349 2002-01-28 Akim Demaille <akim@epita.fr>
13351 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13354 2002-01-28 Akim Demaille <akim@epita.fr>
13356 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13357 AUTOTEST_PATH *after* it was set.
13358 Don't put `.' in the PATH: the user should be precise and `./' if
13359 needed. In addition, given that the test suite does some `cd', if
13360 `.' is in the path, the `tested programs' sections will report
13361 programs found in the test suite's directory, while during the
13362 tests (performed in their own directory), these programs are no
13363 longer visible. In other words, the results is confusing and
13365 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13399 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13400 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.

13407 2002-01-21 Akim Demaille <akim@epita.fr>
13409 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13410 message on invalid options.
13411 * bin/autom4te.in (parse_args): Don't use
13412 Autoconf::General::getopt with non valid options.
13414 2002-01-17 Jim Meyering <meyering@lucent.com>
13416 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

13430 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13431 package.m4, since is really depends upon configure.ac, not
13433 * doc/autoconf.texi (testsuite Scripts): Adjust.
13434 * tests/Makefile.am (package.m4): New.
13435 EXTRA_DIST it since its a source.
13437 2002-01-06 Akim Demaille <akim@epita.fr>
13439 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13440 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13441 and PACKAGE_BUGREPORT from here...
13442 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13444 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13445 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13446 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

13456 * doc/autoconf.texi (Output): Improved wording regarding use of
13460 2001-12-18 Kevin Ryde <user42@zip.com.au>
13462 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13463 sometimes needing writable input.
13465 2001-12-17 Jim Meyering <meyering@lucent.com>
13467 * doc/autoconf.texi (New Macros): Tweak wording.
13469 2001-12-14 Akim Demaille <akim@epita.fr>
13471 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13472 trailing files, don't apply `-rf' to files which might not be
13473 created by configure (core, core.*, and *.core), but just `rm -f'.
13474 Suggested by Jonathan Kamens.
13476 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13478 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13480 2001-12-14 Akim Demaille <akim@epita.fr>
13482 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13484 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13486 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13487 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13488 abs_srcdir, top_srcpath to abs_top_srcdir.
13489 (_AC_OUTPUT_FILES): Adjust.
13490 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13491 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13492 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13494 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13496 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13497 C/Fortran linking on HP/UX, by extracting the Fortran library
13498 search path from the LPATH line in the $F77 -v output.
13500 2001-12-12 Kevin Ryde <user42@zip.com.au>
13502 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13503 forbidden file descriptors table.
13505 2001-11-26 Akim Demaille <akim@epita.fr>
13507 * bin/autoscan.in (%c_keywords): Build it at top level.
13508 Map to 1 in order to simplify its uses.
13510 2001-11-26 Akim Demaille <akim@epita.fr>
13512 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13513 Remove $filepath, useless.
13514 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13515 variables, they are really part of the tokens.
13516 Split the input line on spaces and then look for tokens.
13517 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13518 because of `lex$U.$(OBJEXT)'.
13519 (&scan_files): Use "@list" instead of join.
13520 * doc/Makefile.am (CLEANFILES): Add *.fns.
13522 2001-11-26 Akim Demaille <akim@epita.fr>
13524 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13525 Remove, replaced by...
13526 * tests/wrappl.in: Be common for all the Perl executables.
13527 In particular autoscan and autoheader want -I.
13528 * configure.ac: Adjust.
13529 * lib/autoscan/headers: errno.h is portable.
13531 2001-11-26 Akim Demaille <akim@epita.fr>
13533 * bin/autoscan.in (used): New.
13536 2001-11-26 Akim Demaille <akim@epita.fr>
13538 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13540 (&scan_sh_file): Remove a duplicate pattern.
13541 (&check_configure_ac): Use long options.
13542 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13544 2001-11-26 Akim Demaille <akim@epita.fr>
13546 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13547 Before, having a line containing the opening of a multi line
13548 comment made the whole line be ignored.
13550 2001-11-26 Akim Demaille <akim@epita.fr>
13552 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13553 (testsuite Scripts): Be one of its subsection.
13554 (Autotest Logs): New.
13556 2001-11-26 Akim Demaille <akim@epita.fr>
13558 Test groups are now run two directories deeper.
13560 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13561 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13563 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13564 top_srcdir, builddir and top_builddir.
13565 Use `at_*dir' relatively to the directory containing the
13566 suite, use `*dir' when relatively to the current group dir.
13568 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13570 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13571 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13572 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13575 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13577 * doc/autoconf.texi (Using System Type): Add an example of `case
13578 $host' usage so people quit using `case $target' everywhere.
13580 2001-11-22 Akim Demaille <akim@epita.fr>
13582 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13583 spotted by Jim Meyering.
13585 2001-11-16 Paul Eggert <eggert@twinsun.com>
13587 This patch implements a `long double' suggestion by Oliver Kiddle.
13589 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13590 static, to catch errors if the value isn't known at compile-time
13591 and the compiler supports dynamic arrays. Change its name from
13592 `_array_' to `test_array' to avoid potential name clashes.
13593 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13594 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13595 better than double. Catch a bug in GCC 2.95.2 x86.
13596 * doc/autoconf.texi (C Compiler): Document the above.
13599 2001-11-13 Akim Demaille <akim@epita.fr>
13601 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13603 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13605 2001-11-13 Akim Demaille <akim@epita.fr>
13607 * lib/autotest/general.m4 (AT_INIT): After having run the test
13608 group, go back to the initial directory, not to at_suite_dir.
13610 2001-11-13 Akim Demaille <akim@epita.fr>
13612 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13613 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13614 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13616 (AT_CHECK_CONFIGURE): Use absolute paths.
13617 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13618 The problem is still the old one: there is no means in M4 (that I
13619 know about) to create a defining macro, because there is no means
13620 to create `$1' etc., therefore, the defining macro ``swallows''
13621 all the arguments meant to the defined macro.
13623 2001-11-13 Akim Demaille <akim@epita.fr>
13625 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13626 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13628 * tests/aclocal.m4: Remove, as it is no longer used.
13630 2001-11-13 Akim Demaille <akim@epita.fr>
13632 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13633 variable names when referring to a single test group, or to
13634 `suite' when referring to the whole test suite.
13635 `at_last_test' is removed: m4 compute at_format itself.
13636 (at_stdout, at_stder1, at_stderr): New variables.
13637 (AT_CHECK): Use them.
13639 2001-11-13 Akim Demaille <akim@epita.fr>
13641 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13643 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13644 Do it as soon as a test fails, don't wait till the end of the test
13646 Don't remove $as_me.[0-9]*, since these files no longer exist.
13648 2001-11-13 Akim Demaille <akim@epita.fr>
13650 * tests/tools.at: Use absolute paths, since we are no longer run
13653 2001-11-13 Akim Demaille <akim@epita.fr>
13655 Now that tests are running in their own private dir, there is no
13656 need to list the files to remove at the end of tests groups.
13658 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13659 (AT_data_files, at_data_files): Remove.
13660 (AT_CLEANUP, AT_DATA): Simplify.
13662 Remove the group dir if !debug && !failed.
13663 * tests/atspecific.m4: Adjust.
13665 2001-11-13 Akim Demaille <akim@epita.fr>
13667 Start a new layout for Autotest: `testsuite' creates
13668 `testsuite.dir' in which the at-check-line etc. files are to be
13669 found, and `testsuite.dir/003' where the test group 3 is run.
13671 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13672 at_check_line_file, at_format, at_test_normalized, at_group_dir
13674 Create the directories.
13675 Use absolute paths for at- files.
13676 (AT_CHECK): Adjust.
13678 2001-11-11 Michael Matz <matz@kde.org>
13680 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13682 (m4_car): Properly quote arguments.
13684 2001-11-13 Akim Demaille <akim@epita.fr>
13686 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13687 with stricter rules on LIBOBJS.
13689 2001-11-12 Paul Eggert <eggert@twinsun.com>
13691 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13692 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13695 2001-11-12 Akim Demaille <akim@epita.fr>
13697 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13699 2001-11-12 Akim Demaille <akim@epita.fr>
13701 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13702 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13703 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13704 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13705 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13706 specify to what the macro should be defined (typically to 1).
13708 2001-11-12 Akim Demaille <akim@epita.fr>
13710 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13713 2001-11-12 Akim Demaille <akim@epita.fr>
13715 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13716 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13717 definition used by Automake where LEX is +/- "${missing} lex" and
13718 `missing' itself contains variables.
13720 2001-11-12 Akim Demaille <akim@epita.fr>
13722 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13723 Now that M4sh pushes BODY, the comments were output at the end of
13726 2001-11-08 Akim Demaille <akim@epita.fr>
13728 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13729 that we can trace macros from aclocal.m4.
13730 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13731 obsoleted, and redirect to the former anyway.
13732 Reported by Ralf Corsepius.
13734 2001-11-08 Akim Demaille <akim@epita.fr>
13736 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13737 processed only if present.
13738 * tests/torture.at (Configuring subdirectories): Use autoreconf
13739 instead of successive calls to autoconf.
13740 Add a nonexistent subdirectory to exercise the patch above.
13741 Reported by Ralf Corsepius.
13743 2001-11-08 Kevin Ryde <user42@zip.com.au>
13745 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13746 doesn't accept .S files.
13748 2001-11-07 Akim Demaille <akim@epita.fr>
13750 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13751 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13752 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13753 * bin/autom4te.in (warn_forbidden): New.
13754 (handle_output): Use it.
13755 Read m4_pattern_forbid with messages.
13757 2001-11-05 Akim Demaille <akim@epita.fr>
13759 * bin/autom4te.in (--normalize): Remove.
13760 * lib/autom4te.in: Adjust.
13762 2001-11-05 Akim Demaille <akim@epita.fr>
13764 * tests/Makefile.am (testsuite): Rename this target as...
13765 ($(TESTSUITE)): this.
13768 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13770 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13771 the --prefix option, also remove it's argument.
13773 2001-11-05 Akim Demaille <akim@epita.fr>
13775 * doc/autoconf.texi (testsuite Invocation): Update.
13776 (Writing testsuite.at): Update.
13778 2001-11-03 Akim Demaille <akim@epita.fr>
13780 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13782 2001-11-03 Akim Demaille <akim@epita.fr>
13784 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13785 (&file_name_is_absolute): New, wrappers around routines from
13787 Use and export them.
13788 (&find_configure_ac): Optionally take a directory where to look at.
13789 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13791 Default @ARGV to `.', not find_configure_ac.
13792 (&autoreconf): Argument is a directory.
13793 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13794 * doc/autoconf.texi (autoreconf Invocation): Update.
13796 2001-11-03 Akim Demaille <akim@epita.fr>
13798 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13799 (@export_forward_subs): New.
13800 Add basename, dirname, and fileparse.
13802 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13803 Don't look for aclocal flags if we already know aclocal is not
13805 Move aclocal.m4t only if it exists.
13806 Reported by Ezra Peisach.
13808 2001-11-03 Akim Demaille <akim@epita.fr>
13810 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13811 passed on command line, defaulting to ./configure.ac if present.
13812 (&maybe_autoreconf, File::Find): Remove, unused.
13813 (&autoreconf): If autoconf is not used, don't try to trace.
13815 2001-11-02 Akim Demaille <akim@epita.fr>
13817 * configure.ac: Bump to 2.52g.
13819 2001-11-02 Akim Demaille <akim@epita.fr>
13823 2001-11-02 Akim Demaille <akim@epita.fr>
13825 * config/config.guess, config/config.sub, doc/standards.texi:
13826 * config/lispdir.m4: Update from masters.
13827 * configure.ac: Bump to 2.52f.
13829 2001-11-02 Akim Demaille <akim@epita.fr>
13831 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13832 Don't run aclocal when aclocal.m4 is not from aclocal.
13834 Don't run libtoolize and gettextize if --install is not given.
13836 2001-11-01 Paul Eggert <eggert@twinsun.com>
13838 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13839 be invoked before _AS_LINENO_PREPARE.
13840 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13841 than character ranges.
13843 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13844 invoking AS_BASENAME. Set the locale variables to 'C' if
13845 possible, as POSIX requires this to get the traditional
13847 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13849 2001-10-31 Paul Eggert <eggert@twinsun.com>
13851 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13852 with {}, as that triggers a bug in Bash 2.05.
13854 (_AS_LINENO_PREPARE): Use Sed rather than
13855 Awk. Fix the sed prepass to work even if there are multiple
13856 instances of $LINENO on the same line. Do not substitute for
13857 other variables like $LINENOT. Do not check file dates; such a
13858 check is unreliable on sufficiently fast machines, and removing
13859 the check makes the code simpler and more reliable. Check for
13860 output and chmod failures.
13862 * doc/autoconf.texi (Special Shell Variables): Document
13865 2001-10-31 Akim Demaille <akim@epita.fr>

13872 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13873 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13874 provided, while it is optional.
13875 * configure.ac: Adjust.
13877 2001-10-26 Paul Eggert <eggert@twinsun.com>
13879 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13880 lib/Autom4te/Struct.pm:
13881 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13884 * doc/autoconf.texi (Special Shell Variables): Document some
13885 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13887 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13888 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

13908 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,

13912 Assign to a char* var, to catch strerror_r that returns int*.

14365 2001-09-22 Akim Demaille <akim@epita.fr>
14367 Rely on `$LINENO' when possible instead of `__oline__'.
14369 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14370 `$LINENO' support replacement when not supported.
14371 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14372 them explicitly to be sure they are not output before this section

14386 2001-09-21 Akim Demaille <akim@epita.fr>
14388 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14389 Suggested by Jim Meyering.

14407 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

14409 be used instead of ':'.
14410 * lib/autotest/general.m4: Replace occurrences of ':' in
14411 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14413 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14416 arguments. Fixed a typo.
14418 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14420 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14421 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14423 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14425 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14438 2001-09-19 Akim Demaille <akim@epita.fr>
14440 * lib/autotest/general.m4: Englishoes.
14441 From Tim Van Holder and Alexey Mahotkin.
14443 2001-09-18 Paul Eggert <eggert@twinsun.com>
14445 * doc/autoconf.texi (Common Shell Constructs): New node,
14446 documenting AS_DIRNAME.
14447 (Limitations of Usual Tools): Refer to it when discussing dirname.
14448 Also, update discussion of POSIX standard to reflect latest draft.
14450 * lib/autoconf/c.m4:
14451 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14453 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14454 Do not pass a first argument with leading '-'
14455 to expr, by parenthesizing initial integers that might be negative.
14457 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14458 now merely checks whether it is an error to pass an argument
14461 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14462 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14463 whether it is a (compile-time) error to pass an argument to
14464 getpgrp. This simpler test supports the revised documentation,
14465 and is all that AC_FUNC_GETPGRP's users really need.
14467 2001-09-18 Akim Demaille <akim@epita.fr>
14469 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14477 2001-09-18 Paul Wagland <paul@wagland.net>
14479 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14481 Add test for AS_BASENAME.
14482 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14483 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14484 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14485 * tests/base.at: Fixed the expected responses. The old ones were
14487 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14488 the documentation claims it should (and how it behaved in 2.13).
14490 2001-09-18 Akim Demaille <akim@epita.fr>
14492 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14493 the AC_CONFIG_COMMANDS invocation.
14494 This also solves the name clash problems.
14495 Don't set the package's ID.
14496 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14497 No longer to be shipped.
14498 (version.in): Remove.
14499 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14500 * lib/autoconf/status.m4: Adjust.
14501 Use `m4_PACKAGE_STRING'.
14502 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14503 the only optional argument is the name of the test suite.
14504 Expect `package.m4' to define the package signature.
14505 * lib/autom4te.in (Autotest): Add `package.m4?'.
14506 * tests/Makefile.am (package.m4): New.
14507 * tests/suite.at: ifnames is a victim.
14509 2001-09-18 Akim Demaille <akim@epita.fr>
14511 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14512 AC_LIBSOURCE, AC_CONFIG_FILES.
14513 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14514 program version string doesn't match the package's.
14515 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

14520 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14521 Allow expression to return any value that can fit into unsigned long
14522 (not int, as before). Check for output errors.

14526 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14527 Always include <stdio.h> and <stdlib.h>. Evaluate
14528 the expression in an extra function before these includes. Call
14529 fprintf "%d" only after ensuring the argument is of type 'int'.
14530 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14532 2001-09-17 Paul Eggert <eggert@twinsun.com>
14534 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14535 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14536 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14537 when they don't exist.
14539 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14540 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14543 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14544 version with the version used by fileutils 4.1, except use
14545 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14548 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14550 2001-09-13 Akim Demaille <akim@epita.fr>

14590 * lib/autotest/general.m4 (AT_INIT): Create and remove
14591 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14592 test suites can cohabit.
14594 2001-09-13 Akim Demaille <akim@epita.fr>
14596 * tests/mktests.sh: Don't output banners for empty test files.

14648 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14651 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

14702 2001-09-05 Akim Demaille <akim@epita.fr>
14704 Be ready to handle filenames as stupid as `dnl.at', for if even
14705 the maintainer is dumb enough to do that...
14707 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14708 excellence in M4 quotation: consider `__file__' is active.
14710 And BTW, when invoking m4, pass the --include in the right order:

14791 * man/Makefile.am (.x.1): We really have to pass
14792 autom4te_perllibdir.

14796 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14797 debug scripts, in particular passing explicitly listed tests to

14846 Drop AC_MACRODIR dead for real.
14847 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14848 `autoheader: `config.hin' is created'.
14849 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14851 2001-08-31 Akim Demaille <akim@epita.fr>
14853 * bin/autoheader.in: Rewrite in Perl.

14859 Map --localdir, --autoconf-dir onto it.
14860 Forward autom4te's options instead of interpreting them.
14861 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14862 There is no such envvar since the inception of autom4te.cfg.
14863 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14864 * bin/autoupdate.in: Adjust, and perform more control.

14866 * tests/autoconf: Dittowise.
14868 2001-08-31 Akim Demaille <akim@epita.fr>

14888 find the executables for it.

14890 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14892 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14893 indeed related to running the test suite, while passing
14894 --autoconf-dir and others is related to running non installed
14895 Autoconf executables. So don't do that, leave it to...

14897 * tests/autoscan: New.
14898 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14917 2001-08-29 Akim Demaille <akim@epita.fr>

15384 autom4te.cache (it's a directory, not a file.
15385 * Makefile.am: Ditto (but maintainer-clean-local).
15387 2001-08-15 Akim Demaille <akim@epita.fr>
15389 * bin/autom4te.in (@m4_warning): New.
15390 (&handle_m4): Use it.
15391 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15392 warnings are issued at each run.
15393 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15394 is in the src tree.
15396 2001-08-15 Akim Demaille <akim@epita.fr>

15464 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15465 * doc/autoconf.texi (C Compiler Characteristics): Update

15471 magic values from an object file when cross-compiling.
15472 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15474 2001-08-10 Akim Demaille <akim@epita.fr>
15476 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15478 Suggested by Russ Allbery.
15480 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15482 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15483 current $prefix to the sub-configures.
15485 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15487 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15488 extension (needed on BeOS). Reported by Guido van Rossum.
15490 2001-08-09 Akim Demaille <akim@epita.fr>
15492 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15494 2001-08-07 Akim Demaille <akim@epita.fr>
15496 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15498 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15499 No need to remove the files before and after the each test, before
15500 each test and at the end of the suite is enough.
15501 Display only the children `times', not the shell's.
15502 If the test failed or was skipped, at-times is not available.
15504 2001-08-07 Akim Demaille <akim@epita.fr>
15506 Always produce testsuite.log, including when there are no
15507 failures. This helps getting information on skipped tests, and
15508 duration of the tests. Err, implement the latter btw.
15510 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15511 Dump information on the first run of each test.
15512 (AT_CLEANUP): Create `at-times' containing the duration of the
15515 2001-08-07 Akim Demaille <akim@epita.fr>
15517 The use of `dumpstat' revealed that `len' was used although it
15518 should not. m4_text_wrap was using it, but in the Autoconf world
15519 where it is legal. Hence (i) test M4sh in its own world, not
15520 Autoconf's, and (ii), ahem, fix the bug :)
15522 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15523 does not like `' instead of [].
15524 (AT_INIT): Forbid `^_?AT_'.
15525 And don't output such tokens.
15526 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15527 `script.as', and `autom4te.cache'.
15528 Remove `empty' and `macro' which are no longer used.
15529 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15530 * tests/m4sugar.at: Use it.
15531 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15533 2001-08-07 Akim Demaille <akim@epita.fr>
15535 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15537 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15539 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15541 2001-08-04 Akim Demaille <akim@epita.fr>
15543 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15544 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15546 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15547 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15548 (AC_F77_MAIN): Likewise.
15550 2001-08-04 Akim Demaille <akim@epita.fr>
15552 Don't rely on M4sugar outputting the patterns in files, since we
15553 might process the output _without_ running m4, hence without these
15556 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15557 * bin/autom4te.in (@Request::includes): Remove, unused.
15558 (@Request::source): Rename as...
15559 (@Request::input): this.
15560 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15561 (&handle_output): Fetch the patterns from the traces.
15562 `$forbidden' and `$allowed' are constant: use m//o.
15563 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15564 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15566 2001-08-04 Akim Demaille <akim@epita.fr>
15568 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15569 autoconf', i.e., in addition to caching traces, cache the output.
15571 * bin/autom4te.in (Request::cache): Rename as...
15572 (Request::id): this.
15573 ($cache, $icache, $tcache, $ocache): New.
15574 (&handle_m4): Save M4 output in the cache instead of $tmp.
15575 (&handle_output): Adjust.
15576 (&up_to_date_p): Check that the output cache is up to date too.
15577 (top level): Run `&handle_m4' iff force or the cache is invalid.
15578 Run `&handle_output' if the output cache is more recent.
15580 2001-08-04 Akim Demaille <akim@epita.fr>
15582 * bin/autom4te.in ($force): New.
15583 (&parse_args, &print_usage): -f, --force is a new option.
15584 (&handle_output): CPP directives might have spaces after `#'.
15585 (&parse_args): The first file only can be frozen.
15587 2001-08-04 Akim Demaille <akim@epita.fr>
15589 Don't let autom4te compute the `include' traces several times:
15590 first check that the trace cache file is up to date, and then
15591 compare its timestamp with that of the output.
15593 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15594 the preamble. Don't require 5.005 as Autom4te::General does it,
15595 and better yet (use `use', not `require'!).
15596 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15597 Class::Struct as Autom4te::Struct.
15598 * lib/Autom4te/General.pm (File::stat): Use it.
15599 (&mtime): New, export it.
15600 * bin/autom4te.in: Use it.
15601 Declare `$req' is invalid if it is outdated.

15607 must be proposed to the users.
15609 * bin/autom4te.in (@required_trace): Remove.
15611 (&parse_args, &print_usage): -p, --preselect is a new option.
15612 (&up_to_date_p): Adjust.

15652 (m4_divert_pop): Dump the whole diversion stack when a diversion
15654 * bin/autom4te.in (&handle_output): Remember of the first
15655 occurrence of a possibly undefined macro, not the last.
15656 Complain about the possibly undefined macros in the same order as
15657 the appear in the output.
15658 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15659 * tests/tools.at (autoconf: forbidden tokens, basic)
15660 (autoconf: forbidden tokens, exceptions): No longer sort
15661 autoconf's stderr, as it is now deterministic.
15662 Check that `dnl' is caught.
15664 2001-08-01 Akim Demaille <akim@epita.fr>

15684 `END', as `Autom4te::General::END' will be triggered.
15685 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15686 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
15687 system to run `mv', `rm', and `cmp'.
