1479 regression in sourcing files.
1480 * tests/autotest.at (Using atlocal): New test to catch this.

1491 forks when sanitizing PATH. Always output machine information,
1492 not just when atconfig was located.
1494 Add 'testsuite -C dir'.
1495 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1496 detection...
1497 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1498 argument.
1499 <DEFAULTS>: Delay computation of variables based on $at_dir...
1500 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1501 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1502 <PARSE_ARGS>: Parse new option.
1503 <HELP_TUNING>: Document it.
1504 * tests/autotest.at (Choosing where testsuite is run): New test
1505 for this feature.
1506 (Keywords and ranges): Add test for missing -k argument.
1507 * NEWS: Document this.
1508 * doc/autoconf.texi (testsuite Invocation): Likewise.
1510 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1512 * build-aux/config.guess, build-aux/config.sub,
1513 build-aux/texinfo.tex: Sync from gnulib.
1514 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1515 Likewise.
1517 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1519 * doc/autoconf.texi (Particular Programs): Do not mention the
1520 Autoconf version in which the AC_PROG_INSTALL change was done.
1521 Suggested by Paul Eggert.
1523 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1525 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1526 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1527 mode, we change to the source directory, also set $ac_pwd so we
1528 do not go back to the build tree for the next config subdir.
1529 * tests/torture.at (Deep Package): Extend test to contain two
1530 config subdirs on the top level.
1532 Fix parallel `maintainer-check'.
1533 * Makefile.am (maintainer-check-tests): Depend on `all'.
1534 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1535 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1536 Likewise.
1537 (maintainer-check): Serialize the testsuite runs.
1539 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
1540 in feature string for --enable/--with. Convert to underscore

1544 `install -c file1 file2 dir' works.
1545 * doc/autoconf.texi (Particular Programs): Document this.

1561 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1563 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1564 check_SCRIPTS. Building the wrappers for `all' allows help2man
1565 to use them for the manpages.
1566 Report by Benoit Sigoure.
1568 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1570 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1572 Fix some write failure cases in Autotest.

1577 script executable if it is not complete.
1579 2007-12-12 Eric Blake <ebb9@byu.net>
1581 Fix thinko in earlier patch - m4_join isn't defined yet.
1582 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1583 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1584 (m4_require): Use m4_do, not m4_join.
1586 Fix some whitespace tests on cygwin.
1587 * tests/tools.at (autom4te and whitespace in file names): Restore
1588 font-lock. Create $TMPDIR before it might be used.
1590 Fix spurious testsuite failure with M4 1.4.11.
1591 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1593 Optimize AC_REQUIRE.
1594 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1595 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1596 (m4_require): Avoid extra macro calls.
1598 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1600 * tests/torture.at (srcdir): Fix quoting.
1602 Do not pass top_srcdir to configure scripts in testsuite.
1603 * tests/autotest.at (srcdir propagation): Copy install-sh to
1604 source tree.
1605 (my only test): Drop setting of `top_srcdir'.
1606 * tests/base.at (Input/Output): Likewise.
1607 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1608 config.guess, and config.sub to test source tree.
1609 Drop AC_CONFIG_AUX_DIR setting.
1610 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1611 * tests/torture.at (Substitute a 2000-byte string): Drop
1612 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1613 (Substitute a newline, datarootdir workaround): Likewise.
1614 (Define a newline): Adjust for linenumber changes in configure.ac.
1615 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1617 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1618 if `pwd` contains whitespace.
1620 Quote $abs_top_srcdir in tests.
1621 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1622 * tests/tools.at (Syntax of the shell scripts): Likewise.
1624 * tests/m4sh.at (LINENO): Quote $0.
1626 Fix testsuite program wrapper for whitespace in `pwd`.
1627 The problem here is that the usual mantra is that command
1628 variables can contain arguments, thus we cannot just escape
1629 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1630 $top_builddir/tests directory early in $PATH, so that the
1631 wrappers are found by their plain name.
1632 * tests/wrapper.as: Put $testdir early in $PATH.
1633 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1635 Proper config.status --file/--header and $srcdir escaping.
1636 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1637 characters in $ac_file_inputs.
1638 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1639 accordingly.

1641 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1643 Fix Autotest for whitespace in `pwd`.
1644 * lib/autotest/general.m4 (AT_INIT)
1645 <at_func_create_debugging_script, Driver Loop>:
1646 Quote $at_group_dir.
1647 * tests/autotest.at (whitespace in absolute testdir): New test.
1649 * lib/autom4te.in: Quote @datadir@.
1651 Proper file name escaping in Autoconf programs and Perl modules.
1652 This includes escaping of characters special to the shell
1653 as well as special to Perl, e.g., leading `<' or `>'.
1654 For example, when $file starts with `>', `open ">$file"'
1655 wrongly tries to append to a different file.
1656 * bin/autoconf.as: Fix quoting for autom4te options.
1657 * lib/Autom4te/General.pm (shell_quote): New function, taken
1658 from coreutils, written by Jim Meyering.
1659 (mktmpdir): Use it.
1660 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1661 and open_quote.
1662 * bin/autoreconf.in (parse_args): Likewise.
1663 * bin/autoscan.in (main): Likewise.
1664 * bin/autoupdate.in (main): Likewise.
1665 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1666 * bin/ifnames.in: Likewise, XFile usage fixes.
1667 * tests/tools.at (autom4te and whitespace in file names): Extend
1668 test. Test twice, with special characters allowed on w32, and the
1669 rest. Test leading and trailing whitespace, for `open_quote'.
1670 (autotools and whitespace in file names): New, analogous test.
1671 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1672 by Russ Allbery and Eric Blake.
1674 Sync from Automake.
1675 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1676 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1677 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1678 (update_file, contents): Use it.
1680 * Makefile.am (autom4te-update): Rewrite for git.
1682 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1684 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1686 Fix copyright years.
1687 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1688 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1690 2007-12-04 Eric Blake <ebb9@byu.net>
1692 Manually resync with gnulib, since 'make cvs-update' no longer works.
1693 * build-aux/config.guess: New upstream version.
1694 * build-aux/config.sub: Likewise.
1696 When using older automake, don't downgrade build-aux/texinfo.tex.
1697 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1698 * doc/Makefile.am (TEXINFO_TEX): Add.
1700 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1702 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1703 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1704 #undef as this runs afoul of our new way of creating config.h.
1705 Problem reported by Jim Meyering in
1706 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1708 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1710 Fix autom4te for unusual characters in input file names.
1711 * bin/autom4te.in (files_to_options): Quote active characters
1712 for the shell.
1713 * tests/tools.at (autom4te and white space in file names):
1714 New test.
1716 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1717 Document that Tru64 awk always splits $0.
1719 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1721 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1722 `#AT_STOP_...' line at the end of each test.
1724 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1726 * lib/autotest/general.m4 (AT_INIT): For awk line number
1727 extraction script, ensure `$at_group' has a defined value
1728 even for the empty set, and properly quote its usage inside
1729 the awk script.
1731 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1733 * doc/autoconf.texi (Shell Functions): New chapter. Document
1734 IRIX sh $0 issue in functions, move content from ...
1735 (Portable Shell): ... here.
1736 (Shell Script Compiler): Note that shell functions are not
1737 totally unportable any more.
1739 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1740 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1742 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1743 extracting the line numbers of the last needed test.
1745 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1747 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1748 Fix quoting.
1750 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1752 Fix IRIX testsuite debugging failures: $0 in functions.
1753 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1754 Do not use $0 inside a function, as IRIX sh will set that to the
1755 function name rather than the script invocation name.
1757 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1758 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1760 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1761 to extract test scripts.
1762 (AT_INIT): Extract and cache test script line numbers.
1764 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1766 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1767 subsequent fixups; the awk -> here-document conversion trashes
1768 performance too much with AIX sh.
1770 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1772 * tests/local.at: Do not test m4, perl with AT_TESTED.
1774 Diagnose and guard against write errors dealing with config.status.
1775 The general idea is this: all write failures from `configure'
1776 writing `config.status' are indicated by $ac_write_error, which
1777 is only checked at the end. This is safe because config.status
1778 code is not executed before the file is complete. Other write
1779 failures, be they inside config.status, or in sub shell/awk
1780 scripts spawned from configure or config.status, typically need
1781 earlier checking, as their results are used right afterwards.
1782 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1783 before writing config.status, check afterwards.
1784 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1785 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1786 Set `ac_write_error' for write failures to config.status. Barf
1787 upon write failures to temporary files.
1788 Adjust note about closing and reopening the here-document.
1789 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1790 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1791 reopening the here-document.
1792 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1793 Ensure `ac_write_error' does not escape into config.status.
1794 Also, add a couple of code paths not yet exercised in the test
1795 suite: a config file with input from stdin, and a config header
1796 output to stdout.
1797 Suggestion for catching write errors by Bruno Haible.
1799 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1801 Avoid error with Tru64 awk and testsuite lines with many words.
1802 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1803 reads the testsuite, set the field separator to an unusual value,
1804 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1805 even splits the input if $i, i>0, was never accessed in the script.
1807 Revert 2007-10-17 change.
1808 * TODO: Multiline args in config files and headers mean something
1809 different and are not fixed, see
1810 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1811 Report by Stepan Kasal.
1813 * doc/autoconf.texi (Generic Programs): Fix typo.
1815 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1817 AC_*_TOOL does not canonicalize the prefix
1818 * doc/autoconf.texi (Generic Programs): Do not say that
1819 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1821 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1823 Diagnose write errors in config.status instantiations.
1824 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1825 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1826 on write errors.
1827 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1828 Extend test to also check for some write error failures, using...
1829 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1830 Report by Bruno Haible.
1832 Indentation fixups.
1833 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

1865 * lib/autoconf/status.m4: Fix a couple of comment typos.
1867 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1869 2007-11-13 Jim Meyering <meyering@redhat.com>
1871 Clean up the rule to create "expr".
1872 * tests/Makefile.am (expr): Don't redirect directly to target.
1873 Redirect just once, not for each echo statement.
1874 Use $@, not literal "expr".
1876 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1878 Don't worry about preprocessor when testing long long.
1879 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1880 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1881 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1882 These no longer check for preprocessor flaws.
1883 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1884 Do not check for preprocessor flaws.
1886 2007-11-13 Jim Meyering <meyering@redhat.com>
1888 Adapt dependencies, now that a version change doesn't modify configure.ac
1889 * GNUmakefile: Remove "make clean" kludge.
1890 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1891 configure.ac.
1892 Don't redirect directly to target.
1893 Use $@, not literal "version.m4".
1895 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1897 * doc/autoconf.texi (Making testsuite Scripts): Document
1898 ":;{" shorthand as in previous patch.
1900 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1902 * doc/autoconf.texi (Limitations of Builtins): Document problem
1903 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1904 for the workaround.
1905 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1906 Use ":;{" shorthand.
1907 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1909 2007-11-12 Jim Meyering <meyering@redhat.com>
1911 Add more non-srcdir build support.

1915 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1916 * GNUmakefile (dummy): Remove INSTALL.
1918 Remove racy commands to build scripts in bin/ and tests/.
1919 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1920 are guaranteed to be built, remove the rules that tried to build
1921 them. Before, with a parallel build, these rules could lead to
1922 two processes writing tests/wrapper.in concurrently.
1924 Build in man/ only *after* building in bin/ and tests/.
1925 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1926 in both bin/ and tests/.
1928 Accommodate non-srcdir build-from-checkout.
1929 * build-aux/git-version-gen: Require an additional parameter: $srcdir.

1935 Avoid spurious test failures due to version skew.
1936 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1953 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1955 Fix typos in variable names.
1956 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1958 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1960 Document that $((expression)) is not portable.
1961 * doc/autoconf.texi (Shell Substitutions): Here.
1963 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1965 Ignore configure --help* errors due to LINENO-impaired shells.
1966 * tests/torture.at (Configuring subdirectories, Deep Package):
1967 In the --help* tests in read-only trees, make `.' temporarily
1968 writable again for the `stderr' file, and ignore errors due to
1969 the attempt to write configure.lineno.
1970 Report by Patrick Welche.
1972 2007-11-10 Jim Meyering <meyering@redhat.com>
1974 Generate package.m4 in build-dir, not srcdir.
1975 * tests/Makefile.am (package.m4): Adjust target.
1976 Don't redirect directly to $@.
1977 (CLEANFILES): Add package.m4.
1978 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1979 in $(srcdir).
1980 When running $(AUTOTEST), search "." before searching $(srcdir).
1982 Avoid a race condition that would make parallel "distclean" fail.
1983 * tests/Makefile.am (distclean-generic): Replace the default,
1984 automake-provided rule with an identical one, but with an additional
1985 dependency on distclean-local. Simply adding the dependency would
1986 cause automake not to emit the rule at all.
1987 * BUGS: Building with -jN works, now.
1989 Distribute git-version-gen.
1990 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1991 since GNUmakefile is distributed, and requires it for dist* rules.
1993 Remove two more generated files from version control.
1994 * INSTALL: Remove generated file.
1995 * lib/autoscan/autoscan.list: Remove generated file.
1997 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1999 * GNUmakefile (PATH): Remove stray apostrophes; they become
2000 part of PATH, which isn't wanted here.
2002 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2004 New config files output variable `top_build_prefix'.
2005 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2006 `top_build_prefix'.
2007 * doc/autoconf.texi (Preset Output Variables): Document it.
2008 * NEWS: Update.
2009 Report by Bob Friesenhahn.
2011 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2012 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2013 function, to parametrize arithmetic with expr vs. the shell.
2014 Use it where possible.
2015 Suggestion by Benoit Sigoure.
2017 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2019 Adjust the documentation of autotest WRT atlocal.
2020 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2021 when using Automake, to write a rule to produce atlocal, since it's
2022 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2023 distributed, not atconfig.in.
2025 2007-11-04 Eric Blake <ebb9@byu.net>
2027 Update list information.
2028 * README: Mention new autoconf-commit list.

2035 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2037 * build-aux/.gitignore: Ignore mkinstalldirs.
2039 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2041 2007-11-03 Jim Meyering <meyering@redhat.com>
2043 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2044 * build-aux/git-version-gen: This syncs from coreutils.
2046 Adjust the build procedure so "make check" works reliably.
2047 * README-hacking: Include an extra step between "make" and
2048 "make check" to ensure that the latter passes.
2050 Use just-built tools, when possible.
2051 * GNUmakefile (PATH): Set and export here, ...
2052 (dummy): ... rather than here.
2054 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2055 and Andreas Schwab <schwab@suse.de>
2057 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2058 exit status bug.
2060 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2062 * configure.ac (AC_PREREQ): Require version 2.60, for
2063 AC_PROG_SED, AC_PROG_GREP.
2065 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2066 and Jim Meyering <meyering@redhat.com>
2067 and Andreas Schwab <schwab@suse.de>
2068 and Eric Blake <ebb9@byu.net>
2070 Document a bug in GNU Bash with compound commands and redirections.

2072 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2073 workaround.
2075 2007-11-03 Eric Blake <ebb9@byu.net>
2077 Support m4 1.4.5 in testsuite.
2078 * tests/torture.at (Define a newline): Exclude line numbers in
2079 error message.
2080 Reported by Ralf Wildenhues.
2082 2007-11-03 Jim Meyering <meyering@redhat.com>
2084 Remove automake-provided files from version control.

2089 * build-aux/.gitignore: New file.
2090 Suggestion from Ralf Wildenhues.
2092 2007-11-03 Eric Blake <ebb9@byu.net>
2094 Adjust version comparison to account for git snapshot numbers.
2095 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2096 component separator.

2098 <m4_version_compare>: Document this change.
2099 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2101 2007-10-30 Bruno Haible <bruno@clisp.org>
2103 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2104 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2105 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2106 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2107 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2108 Suggested by Paul Eggert.
2110 2007-10-28 Jim Meyering <meyering@redhat.com>
2112 * README-hacking: Autoconf, Automake, and Perl are required to build.
2113 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2115 2007-10-28 Jim Meyering <meyering@redhat.com>
2117 README-hacking: Recommend running autoreconf -vi.
2118 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2119 so that we use just-built tools when they're available.
2120 Suggestions from Ralf Wildenhues.
2122 2007-10-28 Jim Meyering <meyering@redhat.com>
2124 Make inter-release --version output more useful.
2126 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2127 which indicates that it is built using the 19th change set
2128 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2129 is a prefix of the commit SHA1.
2130 * build-aux/git-version-gen: New file.
2131 * configure.ac: Run it to set the version.
2132 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2133 * Makefile.am (dist-hook): Arrange so that .version appears only
2134 in distribution tarballs, never in a checked-out repository.
2135 * .gitignore: Add .version here, too. Just in case.
2136 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2137 not configure.ac, now that the version number changes automatically.
2139 Ensure that $(VERSION) is up to date for dist-related targets.
2140 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2141 git-version-gen doesn't match $(VERSION), but only for dist targets.
2143 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2145 Fix `Deep Package' failure with a configure script early in PATH
2146 * tests/torture.at (Deep Package): Add `.' early in PATH.

2175 problem reported by Bruno Haible in
2176 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2178 2007-10-22 Eric Blake <ebb9@byu.net>
2180 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2181 preprocessor.
2183 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2185 Don't check for bug in HP-UX 11.00 cpp.
2186 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2187 Use -1ull rather than -1u, since that causes problems with gnulib; see
2188 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2190 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2196 test names.
2198 2007-10-21 Eric Blake <ebb9@byu.net>

2206 escaping of backslash in here-documents.
2208 Fix `Deep Package' test failure on FreeBSD.
2209 * tests/torture.at (Deep Package): Do not add `.' to $PATH
2210 unnecessarily. Do not try running `/bin/sh configure' with a
2211 configure script to be found in $PATH, if the shell does not do
2212 this resolution. Fixes test failure on FreeBSD.
2214 Fix config header generation with AIX awk.
2215 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2216 script, use helper array D_is_set, as `" 0"' does not evaluate

2258 array of banner text from a special diversion.
2259 <PARSE_ARGS_END>: No longer need awk to find banners.
2260 <TESTS>: Banners are no longer processed by main driver loop, so
2261 we no longer need case statement.
2262 (AT_BANNER): Rewrite to populate new diversion.
2263 (AT_SETUP): Each test invokes its own banner. No output is needed
2264 to the TESTS diversion.
2265 * doc/autoconf.texi (Writing Testsuites): Document slight
2266 semantics change.
2267 * tests/autotest.at (AT_BANNERS): Enhance test.

2311 columns.
2312 (TEST_FUNCTIONS): Based on recent changes, rename...
2313 (TEST_GROUPS): ...to this.
2315 Reject FreeBSD m4.

2358 of other write errors.
2359 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
2360 use $as_myself, not $0.
2361 (_AC_INIT_HELP): For --help=recursive, if the subdir does not

3375 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
3376 section titles and other comments; no code change.
3378 2007-05-01 Kevin Ryde <user42@zip.com.au>
3380 * doc/autoconf.texi (Particular Programs): Typo
3381 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
3383 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
3385 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
3386 'configure' will fail if the shell lacks proper support for shell
3387 functions. Suggested by RMS.
3389 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
3391 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
3392 about Solaris /bin/printf '%010000x' 123. Problem reported by
3393 Bruno Haible.
3395 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3397 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3398 for a.* when searching for executables, as this prevents users
3399 from having files like a.c. Problem reported by Ralf Wildenhues in:
3400 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3401 This fixes a problem introduced on 2000-12-19.
3403 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
3405 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
3406 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
3407 via Bruno Haible.
3409 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
3411 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3412 AC_CHECK_TYPE, AC_CHECK_TYPES.
3413 * doc/autoconf.texi (Generic types): C types must be type-names
3414 (the C terminology), not type-ids (the C++ term). C++ types
3415 must not be anonymous.
3416 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3417 for C++; this drops support for anonymous struct and union types,
3418 which were problematic anyway.
3419 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3420 for C++.
3422 2007-04-12 Jim Meyering <jim@meyering.net>
3424 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

3430 Report by Pallav Gupta <pallavgupta@gmail.com>.
3432 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
3434 * doc/autoconf.texi (Generic Types): Document the restrictions
3435 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3436 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3437 with objects too. Document the restrictions on its use.
3438 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3439 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3440 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3441 works but the latter doesn't, then it's a valid type.
3442 This lets people use function types and so forth.
3443 For C++ there doesn't seem to be a simple solution, so leave it alone.
3444 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3445 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3446 AC_CHECK_TYPE; that wasn't documented or necessary.
3448 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3450 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
3451 when cross-compiling.

3463 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
3465 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
3466 obsolescent. Suggested by Bruno Haible.
3467 * NEWS: Document this.
3469 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
3471 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3472 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
3473 default still has the problem. Problem reported by Bruce Korb.
3475 2007-03-28 Stepan Kasal <kasal@ucw.cz>
3476 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3478 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix a

3489 more pitfalls.
3491 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
3493 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3494 checks for unsigned long long int.
3496 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3498 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3499 nonstandard grep R.E. escape sequences.
3501 2007-03-17 Jim Meyering <jim@meyering.net>
3503 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3504 (Limitations of Usual Tools): Also list \< and \>, and mention that
3505 HP-UX's grep, like the one from Solaris, does not support that syntax.
3507 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3509 * doc/autoconf.texi (Specifying Names): `--host' does not
3510 change the build type.
3512 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3514 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3515 suggests AC_CONFIG_HEADERS.
3516 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
3517 AC_CONFIG_HEADERS. Problem reported by
3518 Peter O'Gorman.
3520 2007-02-28 Paul Eggert <eggert@cs.ucla.edu>
3522 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
3523 Problem reported by Paolo Bonzini in:
3524 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
3525 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3526 universal binaries. Problem reported by Elias Pipping.
3528 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3530 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3531 * doc/autoconf.texi (C Compiler): Document this. There is a new
3532 extra argument ACTION-IF-UNIVERSAL.
3533 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3534 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3535 Reindent for sanity's sake.
3537 2007-02-24 Eric Blake <ebb9@byu.net>
3539 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3540 copyright.
3541 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
3542 * lib/autotest/general.m4 (AT_INIT): Likewise.

3545 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3547 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3548 status of rm so we know when it failed.
3549 If cleaning of test dir failed before running the test, warn.
3550 Output the line separator in verbose mode before the warning
3551 to make clear the warning belongs to the following test.
3553 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3555 * doc/autoconf.texi (Parentheses): Mention problem with (( in
3556 shells.

3559 and Paul Eggert <eggert@cs.ucla.edu>
3561 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix quoting
3562 errors introduced in last change.
3564 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3566 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
3567 an actual carriage return. Use "ac_cr" to contain the actual
3568 carriage return.
3569 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3570 with traditional Awk and begin.
3571 * tests/torture.at (Limitations of Builtins): Document the problem
3572 with Bash 2.03 printf.

3576 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3578 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3579 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3580 will not wait for input with a script containing only a BEGIN
3581 rule.
3583 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3585 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

3605 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3607 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3608 latest version.
3609 (Shell Substitutions): Note problems with @{var:=value} etc.
3610 Add a new section for problems with @{#var} etc. Problem noted
3611 by Ralf Wildenhues. See:

3614 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3616 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3617 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3618 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3619 substitution will still be done by the special code.
3620 Report by Jim Meyering.
3622 * doc/autoconf.texi (File System Conventions): Mention that
3623 $PATH_SEPARATOR is for the build system only.

3635 Report against Automake by Patrick Welche.
3637 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3639 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3641 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3643 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3644 early on the reader side, drop stderr of the input to avoid
3645 `broken pipe' error output; this may happen even with shell
3646 builtin `echo' of some bash versions. Reports by Ian Macdonald
3647 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3649 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3651 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

3661 Fix some wording problems noted by Paolo Bonzini in:
3662 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3663 * doc/autoconf.texi (Signed Overflow Examples): Give more
3664 discussion about the allow_superuser_privileges example,
3665 and change it a bit to make things clearer.
3666 (Optimization and Wraparound): Clarify whether the compiler
3667 will generate an infinite loop for the example derived from
3668 Autoconf's mktime test.
3669 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3670 Also, clarify unsigned multiplication overflow.
3672 2007-01-04 Eric Blake <ebb9@byu.net>
3674 * bin/Makefile.am (RELEASE_YEAR): New macro.
3675 (edit): Use it to supply correct copyright year to scripts.
3676 * bin/autoconf.as (version): Use it.
3677 * bin/autoheader.in ($version): Likewise.
3678 * bin/autom4te.in ($version): Likewise.
3679 * bin/autoreconf.in ($version): Likewise.
3680 * bin/autoscan.in ($version): Likewise.
3681 * bin/autoupdate.in ($version): Likewise.
3682 * bin/ifnames.in ($version): Likewise.
3684 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3686 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3687 feedback. The most important changes document what happens when
3688 you convert an out-of-range value to a signed integer type, and
3689 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3690 a + b.
3692 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3693 rewrite, taking notions from the recent discussion on the gcc and
3694 autoconf mailing lists; please see
3695 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3696 and follow the many links.
3697 (Integer Overflow Basics, Signed Overflow Examples):
3698 (Optimization and Wraparound, Signed Overflow Advice):
3699 (Signed Integer Division): New sections.
3701 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3703 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3704 preprocessor macro arguments in traced name.
3705 * doc/autoconf.texi (Defining symbols): Document longstanding
3706 support for AC_DEFINE-ing macros with arguments, and document
3707 behavior when the same variable has multiple AC_DEFINEs.
3708 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3709 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3710 macros directly, giving much shorter and simpler code.
3712 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3714 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3715 space before "$ac_configure_args" to prevent a 'config.status
3716 --recheck' failure if ac_configure_args doesn't contain a leading
3717 space. This works around a problem with the XEmacs configure.ac,
3718 which uses the (undocumented) ac_configure_args variable
3719 inconsistently with Autoconf.
3721 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3723 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3724 Include <limits.h>, and use its INT_MAX to rewrite the
3725 j loop so that it does not overflow 'int'. Problem reported by
3726 Ralf Wildenhues in
3727 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3728 Play it safe by shifting left by 1 rather than multiplying by 2,
3729 as GCC is less likely to optimize this away when the value
3730 is signed (when it assumes overflow leads to undefined behavior).
3731 Also, don't assume time_t uses two's complement.
3733 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3735 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3736 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3737 dumps core on it. Report by Tim Rice.
3739 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3741 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3742 --disable-option-checking to --help output even when
3743 AC_PRESERVE_HELP_ORDER is not used.
3744 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3745 --with argument, rather than argument with [-.] replaced by
3746 underscores.
3747 * NEWS: Fix typo in previous change; the news was in the
3748 wrong section.
3750 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3752 * NEWS: Warnings are now generated by default for unknown
3753 --enable-* and --with-* options.
3754 * doc/autoconf.texi (Option Checking): Renamed from
3755 (Configure Option Checking). Tighten up the wording a bit.
3756 (External Software, Package Options): Cross-reference to Option
3757 Checking, and use this to shorten our section.
3758 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3759 "$x" to test "x$foo" != x.
3760 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3761 Don't warn if $enable_option_checking is "no".
3762 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3763 ac_unrecognized_opts to the empty string.
3764 Don't echo the unrecognized opts, as this might mishandle
3765 backslashes or leading -.
3766 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3767 usage next to the other --disable-FEATURE options in the
3768 help string.
3770 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3772 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3773 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3774 Print warning for unrecognized --with and --enable options
3775 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3776 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3777 Disable option checking when subdirs are configured.
3778 (AC_OUTPUT): If warnings are enabled, print warning about
3779 unrecognized --with and --enable options at the end of
3780 the configure output (as well as at the beginning).
3781 * doc/autoconf.texi (Option Checking): New node.
3782 Document new option warning functionality.
3784 2006-12-16 Eric Blake <ebb9@byu.net>

3787 * NEWS: Start news for current version.
3789 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3791 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3792 Define HAVE_GETMNTENT to 1, not to the empty string.
3793 Problem originally reported by Jochen Friedrich in
3794 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3796 This change prompted by a problem report by Andrey Simonenko in
3797 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3798 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3799 object-like macros only, in the traditional portable character
3800 set.
3801 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3802 Warn about attempts to define things that are not identifiers.
3803 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3804 awful hack that AC_DEFINEd macro names containing parentheses.
3806 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3808 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3809 too drastic, even if Texinfo in theory requires it for info mode.
3811 (config.status Invocation): Renamed back from Recreating a
3812 Configuration).
3813 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3814 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

3823 * NEWS: Document changes with echo and printf, and the lack
3824 of limits on the total size of multi-line values of substituted
3825 variables, and the AC_FUNC_FSEEKO fix.
3827 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>

3839 * BUGS: Remove mention of VPATH problem, since it's now documented
3840 not to be a bug in the Autoconf build procedure itself, but rather
3841 a problem with the proprietary `make' programs.
3843 * doc/autoconf.texi (Build Directories): Add a cross reference
3844 to VPATH and Make.
3846 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3847 * doc/standards.texi: Sync from gnulib.
3849 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3850 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3851 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3852 generated automatically.
3854 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3856 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3857 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3858 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3860 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3862 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3863 `CEOF$ac_eof' special marker, the awk script cannot contain a
3864 line matching `^CEOF', so this is not needed any more.
3865 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3866 special marker in the test.
3868 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3870 * tests/tools.at (autom4te preselections): Use `find -newer';
3871 remove one of the sleeps.
3873 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3874 more readable, using ...
3875 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3877 * doc/autoconf.texi (autoheader Invocation): Do not double-
3878 quote the parameter of `AH_BOTTOM' in the example.
3880 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3882 * doc/autoconf.texi (Configuration Headers): Remove the
3883 example with multiple input files.
3884 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3885 multiple input files.
3887 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3889 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3890 creating the awk substitution script, handle one input line at a
3891 time, so that the maximum length of a substituted (multi-line)
3892 value is not limited by the size of the sed pattern space.
3893 The trade-off is a slightly repetitive sed script.
3894 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3895 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3896 * tests/torture.at (Substitute a 2000-byte string): Increase the
3897 test with several long lines, they should not be caught by sed
3898 limits any more.
3900 * tests/tools.at (autom4te preselections): New test, to flag
3901 entries missing from autom4te.cfg.
3902 Report by David Byron <dbyron@hheld.com>.
3904 * tests/torture.at (Substitute a 2000-byte string): Actually use
3905 AC_PROG_AWK, so the last change works as intended.
3906 (Substitute and define special characters): Likewise.
3907 (Substitute a newline): Likewise.
3909 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3910 instead of `awk' consistently.
3911 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3912 * tests/torture.at (Torturing config.status): Test both the
3913 result of AC_PROG_AWK and plain awk.
3914 (Substitute a 2000-byte string): Likewise.
3915 (Substitute and define special characters): Likewise.
3916 (Substitute a newline): Likewise.
3918 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3920 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3921 can be assigned to a function pointer. Problem reported by
3922 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3923 part of a patch by Ralf Wildenhues in that same bug report.
3925 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3927 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3928 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3930 2006-12-01 Eric Blake <ebb9@byu.net>
3932 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3933 cross-compiling from cygwin to mingw.
3934 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3935 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3936 to lib/autoconf/c.m4.
3938 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3940 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3941 string for more reliable failure. Wrap the entire test that
3942 causes the broken Solaris printf to dump core, in a subshell,
3943 so the segmentation fault message is reliably suppressed.
3944 Fix shell expansion errors by using /usr/ucb/echo always;
3945 avoid an error on systems without it by another subshell.
3946 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3947 subshell-$as_echo to `as_echo', for better error message.
3949 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3951 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3952 `BASH_SOURCE' contain a newline, set them to empty, as they may
3953 not be unset.
3955 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3957 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3958 years and is too hard to maintain now. The last straw was
3959 reported by Jerker Baeck in
3960 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3961 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3962 * doc/autoconf.texi (Particular Functions): Move
3963 AC_FUNC_SETVBUF_REVERSED from here...
3964 (Obsolete Macros): ... to here. Say that it does nothing now.
3965 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3966 Turn into (almost) a no-op.
3968 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3969 (AC_C_VOLATILE):
3970 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3971 These macros are obsolescent and new applications shouldn't need them.
3972 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3973 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3974 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3975 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3976 (AC_FUNC_VPRINTF): Likewise.
3977 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3978 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3979 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3981 * doc/autoconf.texi (Setting Output Variables): Mention that
3982 @VAR1@VAR2 has unspecified behavior. Problem reported by
3983 Ralf Wildenhues.
3984 * NEWS: Mention this.
3986 * Makefile.am: Put only a single '#' into the copyright notice,
3987 so that it's also present in the output file. Standardize wording
3988 in makefile copyright notices to match GNU coding standards.
3989 * bin/Makefile.am: Likewise.
3990 * doc/Makefile.am: Likewise.
3991 * lib/Makefile.am: Likewise.
3992 * lib/freeze.mk: Likewise.
3993 * lib/autoconf/Makefile.am: Likewise.
3994 * lib/autoscan/Makefile.am: Likewise.
3995 * lib/autotest/Makefile.am: Likewise.
3996 * lib/m4sugar/Makefile.am: Likewise.
3997 * man/Makefile.am: Likewise.
3998 * tests/Makefile.am: Likewise.
3999 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4000 one-line file.
4002 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4004 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4005 in the sed script that mangles the awk script: delete up to the
4006 first exclamation mark only.
4007 * tests/torture.at (Substitute and define special characters):
4008 Test '!' too.
4010 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4012 Rewrite config files generation: avoid quadratic growth in
4013 the number of substituted variables by using awk instead of sed
4014 for the bulk of the substitutions.
4015 * NEWS: Mention this.
4016 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4017 forbidden in the output (and thus input) file.
4018 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4019 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4020 generate just one large awk script for substitutions,
4021 eliminating much of the earlier complexity, while adding some
4022 new complexity. Only expand the substitution templates at
4023 configure time, for smaller configure script size. If
4024 _AC_SUBST_FILES are used, test 'awk' for working getline support
4025 at config.status time. If absent, interpolate through the
4026 shell. The awk script was written with much help
4027 from Paolo Bonzini and Paul Eggert.
4028 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4029 (_AC_SED_FRAG_NUM): Likewise.
4030 (_AC_SUBST_CMDS): Renamed from...
4031 (_AC_SED_CMDS): ...this.
4032 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4033 * tests/torture.at (Substitute a 2000-byte string): Also
4034 substitute a line with 1000 words, and a variable with several
4035 long lines.
4036 (Substitute and define special characters): Test awk special
4037 characters, and put substitution input strings `@foo@' in the
4038 output, to test that no recursion happens; test several other
4039 combinations from Paolo Bonzini.
4041 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4043 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4044 that replaced echo with AS_ECHO where this wasn't necessary.
4045 Problem reportd by Ralf Wildenhues.
4046 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4047 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4048 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4050 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4052 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4054 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4056 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4057 that traditional Awk lacks 3-arg "split". It has it.
4058 Mention that FS must be a single character, and a few other
4059 99-byte limits of traditional Awk.
4060 Mention that if (i in a) doesn't work with traditional Awk.
4062 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4064 * tests/autotest.at (BSx641-newline in command):
4065 (BS-BS-newline in command, BSx640-newline in command):
4066 (Newline-CODE-BS-newline in command):
4067 (Single-quote-BS-newline in command):
4068 (Single-quote-newline-BS-newline in command):
4069 Use printf '%s\n' instead of echo, for portability to hosts
4070 where echo interprets backslashes. This will break on hosts
4071 that lack printf, but for now let's assume all such hosts
4072 are dead (if not, we should get reports of test failures).
4074 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4076 'echo' has some portability problems, when given a first argument
4077 with a leading '-', or when given any argument containing '\'.
4078 Avoid using 'echo' in these cases.
4079 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4080 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4081 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4082 * lib/autotest/general.m4 (AT_INIT): Likewise.
4083 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4084 argument might be unportable.
4085 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4086 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

4088 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
4089 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
4090 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
4091 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
4092 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.

4099 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4100 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
4101 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
4102 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4103 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4104 * bin/autoconf.as: Redo verbose flag implementation, as the old
4105 scheme wouldn't work with AS_ECHO.
4106 * lib/autotest/general.m4 (AT_INIT): Likewise.
4107 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4108 Don't use ECHO_T, since ECHO_N is now reliable.
4109 * lib/autotest/general.m4 (AT_INIT): Likewise.
4110 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4111 rather than using a here-document to put the script into a file.
4112 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4113 use AS_ECHO.
4114 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4115 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4116 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4117 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4118 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4119 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4120 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4121 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4122 operand, as AS_ECHO requires. Avoid double file name expansion.
4123 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4124 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4125 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4126 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4127 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4128 Double-quote strings that would otherwise contain M4 comments.
4129 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4131 * configure.ac (AC_INIT): Bump to 2.61a.
4132 * NEWS: Likewise.
4134 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4136 Version 2.61.
4138 * configure.ac (AC_INIT): Bump to 2.61.
4139 * NEWS: Likewise.
4141 * tests/autotest.at (Macro with backslash in a test title):
4142 Comment out for now, as this tests neither fails nor passes
4143 reliably. Problem reported by Ralf Wildenhues.
4145 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4147 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4148 in previous change, which caused test failures.
4150 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4152 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4153 code for --enable, --disable, --with, and --without to...
4154 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4155 * doc/autoconf.texi (Package Options):
4156 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4158 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4160 Import these changes from config via gnulib:
4162 2006-11-15 Ben Elliston <bje@gnu.org>

4195 Import these changes from texinfo via gnulib:
4197 2006-11-08 Karl Berry <karl@gnu.org>

4201 no further ado.
4203 2006-11-05 Karl Berry <karl@gnu.org>
4205 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

4219 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4221 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4222 benefit of platforms like Solaris+GCC where it is common to have a
4223 non-working g++ installation.
4225 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4226 and Joel E. Denny <jdenny@ces.clemson.edu>
4227 and Paul Eggert <eggert@cs.ucla.edu>
4229 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4230 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4231 ./micro-suite.
4233 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4235 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4236 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4237 Imported from a similar patch to gnulib by Bruno Haible.
4239 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4241 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4249 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
4250 Matthew Woehlke.
4252 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4254 * tests/torture.at (Configuring subdirectories): Do not skip
4255 Automake 1.10 nor future Automake 11.1 (sic).
4257 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4258 and Stepan Kasal <kasal@ucw.cz>
4260 Handle special characters in test case titles correctly.
4261 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4262 properly.
4263 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4264 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4265 argument. Extend to check titles printed by ./micro-suite and
4266 ./micro-suite -l and the title in micro-suite.log.
4267 (Backquote in a test title,
4268 Single-quote in a test title,
4269 Double-quote in a test title): Don't expect failure anymore.
4270 (Backslash in a test title): Put a non-whitespace character after the
4271 backslash so that Bourne shells might actually see it as an escape
4272 sequence.
4273 (Brackets in a test title,
4274 Pound in a test title,
4275 Comma in a test title,

4278 Macro with single-quote in a test title): New tests.
4279 (Macro with backquote in a test title,
4280 Macro with double-quote in a test title,
4281 Macro with backslash in a test title): New tests expected to fail.
4282 * tests/torture.at (#define header templates): M4-quote this title in
4283 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4284 The visible effect was a stray [] in the testsuite output.
4286 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4288 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4289 `trap ... 0' inside a function, for AIX sh.
4291 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4293 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4294 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4295 5363) simply issues a warning when dividing by zero at compile
4296 time. Problem reported by Elias Pipping.
4298 2006-10-26 Eric Blake <ebb9@byu.net>
4300 * THANKS: Update.
4301 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4302 show effect on macros that expand with commas.
4303 Reported by Joel E. Denny.
4305 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
4306 Also work with M4 1.4.8.
4308 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
4310 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
4311 Jim Meyering.
4313 2006-10-25 Stepan Kasal <kasal@ucw.cz>

4316 `--force' always rewrites the output file.
4318 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4320 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

4327 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4329 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4330 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4331 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4332 reported by Nelson H. F. Beebe for Coreutils 6.4.
4334 * tests/tools.at (autoconf --trace: user macros): Remove test
4335 for tracing multiline macros, since m4 1.4.7a uses a different
4336 way to number lines. Problem reported by Ralf Wildenhues.
4338 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4340 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4341 /dev/null since the heuristics for interactive behaviour was
4342 fixed in CVS m4.
4344 * bin/autom4te.in: With --force, always refresh the output
4345 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4347 * bin/autoconf.as: Fix the verbose message at the end.
4349 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4364 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4365 AC_CACHE_CHECK_INT, since it's no longer public.
4366 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4367 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4369 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4371 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
4373 2006-10-19 Eric Blake <ebb9@byu.net>

4387 Standards.

4395 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4397 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4398 looking for special shell characters.
4399 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4400 macro defined by AS_VAR_PUSHDEF before passing it as a
4401 parameter.
4402 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4403 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

4412 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4414 (Imported from Automake.)
4415 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4416 which incorrectly sets the mode of an existing destination
4417 directory. In some cases the unpatched install-sh could do the
4418 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4419 system. We hope this is rare in practice, but it's clearly worth
4420 fixing. Problem reported by Alex Unleashed in
4421 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4422 Also, don't bother to check for -m bugs unless we're using -m;
4423 suggested by Stepan Kasal.
4425 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4427 Import this change from Automake:
4429 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4430 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4431 is enabled by default with gnu and gnits strictness.
4432 Report from Bruno Haible.
4434 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4435 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4436 gnu and gnits modes.
4438 Import this change from Config:
4440 2006-09-20 Ben Elliston <bje@gnu.org>
4441 * build-aux/config.sub (score, score-*): New.
4443 Import this change from Gnulib:
4445 2006-09-16 Karl Berry <karl@gnu.org>
4446 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4447 to avoid sectioning errors.
4449 Import these changes from Texinfo:
4451 2006-10-04 Karl Berry <karl@gnu.org>
4452 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4453 (\quoteexpand): rename to \rquoteexpand.
4454 (\codequoteleft): new def, to look for @set codequotebacktick.
4455 (\lquoteexpand, \quoteexpand): new defs.
4456 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4457 (\code): must use new \...Char values, since now ` is active.
4459 2006-08-26 Karl Berry <karl@gnu.org>
4460 * build-aux/texinfo.tex (\textdegree): New command.
4462 2006-08-12 Karl Berry <karl@gnu.org>
4463 * build-aux/texinfo.tex (error \box0): smaller font.
4465 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4467 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4469 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4471 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4472 added to the template can get mangled.
4474 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4476 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4477 include the default headers, and redefine obstack_chunk_alloc
4478 and obstack_chunk_free. Fixes false failure with glibc.
4480 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4482 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4483 for backward compatibility with Libtool 1.5.22. Problem reported
4484 by Ralf Wildenhues.
4486 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4488 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4489 AC_PROG_CC.
4490 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4492 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4494 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4495 the NonStop platform.
4496 * doc/autoconf.texi (Posix Variants): Likewise.
4497 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4499 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4500 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4501 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4502 Use a better substitute, by inspecting the output of "ls"
4503 rather than just using ":".
4504 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4505 rather than AS_EXECUTABLE_P, since we needn't worry about
4506 non-regular files here.
4508 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4509 due to configuration hassles with this. See Tonya Underwood's report
4510 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4511 * doc/autoconf.texi (Special Shell Variables): Likewise.
4513 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4514 Stepan Kasal <kasal@ucw.cz>
4516 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4517 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4519 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4521 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4522 initialization which is not inherited through the environment
4523 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4524 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4526 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4528 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4529 problems with mkdir -p -m.
4531 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4533 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4534 comment about ac_cpp_err; it was incorrect, and anyway
4535 ac_cpp_err is being removed below.
4536 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4537 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4538 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4539 nobody uses it.
4540 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4541 with werror_flag and conftest.err and so forth. This is more
4542 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4543 and anyway the user shouldn't normally want to see this gorp logged.
4544 Problem reported by Ralf Wildenhues.
4545 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4546 empty, not 'no', since the rest of the code uses 'test -z'.
4548 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4550 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4551 Use a single call to AC_DO_TOKENS rather than multiple, for
4552 efficiency.
4553 (_AC_LINK_IFELSE): Test that resulting file is executable.
4554 Problem reported by mwoehlke in
4555 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4557 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4558 than creating a file to use with test -x; this is much faster.
4560 2006-10-02 Bruno Haible <bruno@clisp.org>
4562 * lib/autom4te.in (Automake-preselections): Add
4563 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4565 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4567 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4568 standard error, `experr' should be used, not `expout'.
4570 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4572 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4573 fseeko testing program twice; just use the earlier result.
4574 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4575 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4576 still doesn't let the program compile.
4577 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4578 failed.
4580 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4581 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4582 include it, without including anything else.
4583 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4584 expressions.
4585 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4587 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4589 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4590 `error.h', and include it, for a `error_at_line' prototype.
4591 Use a nonempty format string in the link test.
4592 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4593 for a declaration of wait3.
4595 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4597 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4598 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4599 can apply to constants too, and that it checks for macro defns.
4600 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4601 and simply cast the identifier to void. This handles structure
4602 values. Problem reported by Ralf Wildenhues.
4603 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4605 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4607 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
4608 structure, and function symbols.
4610 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4660 --error-output, to avoid warnings with M4 2.0.
4662 2006-09-19 Stepan Kasal <kasal@ucw.cz>
4664 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

4675 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
4676 mistaken comment: the path has to be relative; do not use
4677 the path at runtime.
4679 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4681 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

4685 for both changes.
4686 * doc/autoconf.texi (Setting Output Variables): Fix example to

4689 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4691 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
4692 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
4693 for the existence of the directory at configure-time. That's
4694 too late, anyway. Problem reported by Stefan Seefeld.
4696 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4697 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4698 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4700 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4702 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4703 works with GNU M4 1.4.3 again; make the normalized form
4704 match the current m4 message; fix the description.
4705 * test/tools.at (autom4te cache): Adapt to the change.
4707 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4709 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4710 to catch glibc bug 2821
4711 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4713 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4714 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4715 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4716 assume C89.
4718 2006-09-08 Stepan Kasal <kasal@ucw.cz>

4738 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4739 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4740 accept files with extension `.f'. For consistency, also prefer
4741 xlf over f77.
4742 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4743 from last patch.
4745 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

4758 before AC_PROG_FC, due to a bug in Autoconf.
4760 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
4762 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
4763 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
4764 except the first two arguments are reversed.
4765 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4766 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4767 caches nor outputs a diagnostic. Suggested by Bruno Haible.
4768 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
4769 equivalent to the old AC_COMPUTE_INT.
4770 (AC_COMPUTE_INT): No longer caches or reports. New signature.
4771 All uses changed to AC_CACHE_CHECK_INT.
4772 * tests/base.at (AC_CACHE_CHECK_INT): New test.
4773 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
4775 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
4777 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4778 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4779 programs should use their Gnulib counterparts.
4780 * doc/autoconf.texi (Particular Functions): Likewise.
4781 (Macro Names, testsuite Invocation): Replace uses of these
4782 obsolete macros with uses of non-obsolete macros.

4806 simplify the code.
4808 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
4810 Fix Lex library problem reported to us by Julio Garvia.
4811 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
4812 for the default, which the user can override.
4813 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4814 deal with LEXLIB.
4815 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4816 didn't work if some values were cached but not others. Test for
4817 broken lex libraries like native ia64-hp-hpux11.22; see
4818 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4819 work around the problem by preferring an empty LEXLIB to -lfl or
4820 -ll. Let the user set LEXLIB='' to indicate no library needed.
4822 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4823 * README: Likewise.
4824 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4925 * doc/autoconf.texi (Particular Programs): Mention that
4926 @INSTALL@ and @MKDIR_P@ may vary for different output files.
4927 Reported by Alexandre Duret-Lutz.
4929 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
4931 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
4932 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
4933 Bill Northcott in
4934 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

4948 -Wundef -Werror". Problem reported by David Fang in
4949 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
4950 * doc/autoconf.texi (Header Templates, Default Includes):

4988 --help' should mention that `--version' outputs configuration
4989 settings. Report by Bruno Haible.
4991 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4993 Fix test suite failures reported by Pierre in

5009 less skeptical about "volatile", after discussion with
5010 Bruno Haible on bug-gnulib.

5012 leading white space from text. From Bruno Haible.
5014 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5016 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5017 compiler complains about it, even if things works after the
5018 complaint. Problem reported by Peter O'Gorman.
5020 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5021 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5022 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5024 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5026 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

5050 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5051 more globally, since the 2006-06-30 patch didn't suffice. Problem
5052 reported by Keith Marshall. Also, don't bother with builddir2,
5053 since it shouldn't be needed any more.
5055 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5057 * doc/autoconf.texi (Generic compiler characteristics):
5058 Document AC_COMPUTE_INT. Fix wrong statements on Default

5074 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5076 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5077 Require that long long int be at least 64 bits wide. C99 requires
5078 this and enough programs depend on it so we should check for it.
5079 Bruno Haible reports in
5080 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5081 that long long int is 32 bits wide with some nonstandard compilers.
5082 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5084 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5086 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5087 to a nonexistent file, so that we don't have to worry about
5088 a local site configuration that doesn't use /usr/local.
5089 Problem reported by Keith Marshall in
5090 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5092 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5094 * doc/autoconf.texi: Be more consistent about using @acronym with
5095 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5096 quite right (it talked about "OSF/Tru64", even though the
5097 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5098 and it even mentioned "OSF 4"!) and at this point there's little
5099 reason to talk about OSF any more, since it died in 1994.
5100 (Specific Compiler Characteristics): Simplify example of
5101 negative-size array.
5102 (File Descriptors): Reorder to make the text flow better.
5103 Remove joke about "appreciate the various levels"; I didn't get it.

5105 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5106 (File Descriptors, Limitations of Usual Tools):
5107 Tone down the advice against renaming or removing open files.
5108 (Limitations of Usual Tools): Add a new section, on 'rm'.
5110 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5112 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5113 -lXt in LIBS, idea from Karsten Hopp; this was due since
5114 this change:
5116 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5117 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5118 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5119 (which belong to Xt, not X itself). See Debian bug 327655.
5121 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5123 * configure.ac (AC_INIT): Bump to 2.60a.

5143 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5144 not defined.
5145 * doc/autoconf.texi (Changed Directory Variables): New node,
5146 to document the whole `datarootdir' business a bit better.
5147 * NEWS: Update.
5148 * tests/torture.at (datarootdir workaround): Extend test.
5149 Prompted by report by Alexandre Julliard.

5159 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5160 about literal '${datarootdir}' if a definition is found in the
5161 output file.
5163 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5165 * NEWS: Use "M4" rather than "m4" when appropriate.
5166 Problem reported by Eric Blake.
5167 * doc/autoconf.texi: Likewise.
5168 Use @acronym around BSD, GCC, and GNU when appropriate.
5169 (Why GNU M4): Renamed from "Why GNU m4".
5170 (Redefined M4 Macros): Mention that Posix
5171 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5172 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5173 to int.
5175 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5177 * bin/autom4te.in (handle_output): Do not forbid the empty
5178 pattern.
5179 * tests/tools.at (autoconf: the empty token): New test.
5181 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5183 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5184 calls, so that we do not care whether they are LIFO or FIFO;
5185 in the m4_wrap, do not check which diversion is the topmost
5186 one, just check that the stack is balanced at the end.
5187 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5188 base diversion forever--pop the previous diversion before
5189 opening the new one; consequently, remove the m4_wrap call.
5190 * lib/autotest/general.m4 (AT_INIT): Likewise.
5191 * tests/m4sugar.at: Do not use
5192 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5194 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5195 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5197 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5198 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5199 Rework example of m4wrap token-pasting trouble so that it doesn't
5200 care whether it's LIFO or FIFO.
5201 Fix some "contrary to"s that are awkward in English.
5203 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5205 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5206 to `yes' instead of `int$1_t' if the type is found, for more
5207 consistent configure output (where $1 is the number of bits).
5208 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5209 Suggested by Bruno Haible.
5211 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5212 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5213 with system headers. Report by Bruno Haible.
5215 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5217 * config/config.guess, config/config.sub: Sync from upstream.
5219 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5220 in order to avoid picking up an older installed frozen m4sh.m4f.
5221 Besides an outdated shell startup, this could have been created
5222 by an earlier M4 version with incompatible frozen file format.
5224 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5226 * README: Recommend m4 1.4.4 instead of 1.4.3..
5227 * doc/autoconf.texi: Likewise.
5228 (Special Chars in Names): Say that $(.FOO) is portable, as
5229 suggested by Stepan Kasal.
5230 (Installation Directory Variables, Build Directories):
5231 (Automatic Remaking, Subdirectories, Fortran Compiler):
5232 (Making testsuite Scripts, Defining Directories):
5233 Quote variable usages better.
5234 (Making testsuite Scripts): Add clean-local rule to makefile
5235 snippet, by Eric Blake.
5236 (Installation Directory Variables): Fix table item font.
5237 Reword slightly to clarify. Generalize advice about
5238 not using special characters to include all file-related
5239 vars, not just VPATH.
5240 (Special Chars in Variables): Warn about special characters in
5241 $(srcdir) too.
5242 (Assignments): Clarify default-value example as suggested by
5243 Ralf Wildenhues in
5244 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5245 (Special Shell Variables): Note leading ./ or ../, as suggested
5246 by Eric Blake.
5247 (Limitations of Builtins): Under cd, warn about CDPATH.
5248 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5249 Ralf Wildenhues.
5251 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5253 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5254 `@var', for texi2html.
5255 (Systemology): Some more word wrapping, for DVI output.
5256 (autom4te Invocation): The short option for `--melt' is `-M',
5257 not `-m'.
5259 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5261 * doc/autoconf.texi: More formatting and English tweaks,
5262 many suggested by Ralf Wildenhues.
5263 Reword to avoid "@code{...}'s" and the like, since it's ugly
5264 with Emacs info mode. discontents -> woes.
5265 Put a few "will"s back. time stamp -> timestamp.
5266 side-effect -> side effect.
5268 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5270 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5271 Warn about $@ not persisting. Problem reported by Julien Danjou in
5272 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5273 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5274 Mention other special chars, too.
5276 2006-06-14 Eric Blake <ebb9@byu.net>
5278 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5280 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5282 * doc/autoconf.texi: Some systematic minor improvements, as
5283 follows. Use "makefile" when talking about makefiles
5284 generally (which might be named "makefile" or "Makefile" or even
5285 "foo.mk"), "Makefile" when talking about a specific makefile
5286 called "Makefile". This unclutters the text from weird quotes
5287 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5288 values" rather than "@var{foo}s" and similar constructs containing
5289 "}s". Use "Make rules" rather than "Makefile rules". Minor
5290 English-language improvements. Change the prefix "sub-" to "sub"
5291 and "re-" to "re".
5292 Put blank lines around examples more consistently.
5293 Avoid "rather" and "very" as intensifiers.
5294 Avoid "will" as an auxiliary.
5295 (Limitations of Make): Split this node into....
5296 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5297 (Leading _ in Macro Names, Backslash-Newline-Newline):
5298 (Backslash-Newline Comments, Long Lines in Makefiles):
5299 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5300 (obj/ and Make, make -k Status, VPATH and Make):
5301 (VPATH and Double-colon, $< in Explicit Rules):
5302 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5303 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5304 New nodes, resulting from splitup of Limitations of Make.
5305 All cross-references changed. Raise the top node from
5306 a section to a chapter, and all subnodes accordingly.
5307 Redo the introductory wording to match the new organization.
5308 (Installation Directory Variables): Use an example that is
5309 closer to what Autoconf actually does. Mention that VPATH's
5310 value should not contain metacharacters or white space.
5311 (Fortran Compiler): Fix a VPATH bug in an example.
5312 (Leading _ in Macro Names): Mention that this problem is no longer
5313 of practical concern.
5314 (VPATH and Make): Reword the advice to make it clearer
5315 that Autoconf and Automake support VPATH in non-GNU make, but
5316 many packages have bugs in this area.
5317 ($< in Explicit Rules): Refer to Build Directories rather
5318 than using a (non-VPATH-safe) example.
5319 (Automatic Rule Rewriting): Mention the sort of disaster that
5320 can ensue with Solaris-style rule rewriting with VPATH.
5322 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5324 * doc/install.texi (Compilers and Options): Weaken the
5325 suggestion to use GNU make for VPATH builds.
5327 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5328 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5330 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5331 in regular expression.
5333 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5335 * doc/autoconf.texi (Installation Directory Variables):
5336 Drop extra @samp from `@table @samp' item.
5337 (Limitations of Usual Tools): Comment fix.
5338 Do not nest @samp just to point to other table items.
5339 (Writing testsuite.at) <AT_CHECK>: The second argument to
5340 `@dvar' is already @samp'ed.
5341 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5342 do not use @var in the second argument.
5344 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5346 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5347 $as_shell.exe too. Problem reported by Andreas Buening in
5348 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5350 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5352 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5353 `unused variable' compiler warning, for `-Wall -Werror'.
5354 Reported by Jaap Haitsma in
5355 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5357 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5359 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5360 case the compiler dumps core. Problem reported for
5361 OpenServer 5.0.7 by Tim Rice in
5362 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5363 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5364 Likewise.
5366 2006-06-06 Tim Rice <tim@multitalents.net>.
5368 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5369 "ERROR" only shows up in "make check" output if there is an
5370 error.
5372 2006-06-06 Eric Blake <ebb9@byu.net>
5374 * tests/tools.at (automatically allowed tokens): Fix typo.
5376 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5378 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5380 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5381 typically overflows on x86 CPUs, even though the C standard
5382 requires otherwise.
5384 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5386 * configure.ac (AC_INIT): Bump to 2.59e.
5387 * NEWS: Update.
5389 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5391 Version 2.59d.
5393 * config/texinfo.tex: Sync from upstream.
5395 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5396 seen, invoke libtoolize with `--ltdl' argument.
5397 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5398 * NEWS: Update.
5399 Suggested by Eric Blake.
5401 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5403 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5404 reported by Ralf Wildenhues.
5405 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5407 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5409 * THANKS: Update.
5411 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5413 * doc/autoconf.texi: Modernize some of the references to Solaris.
5415 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5417 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5418 message issued by AC_REQUIRE.
5419 * tests/m4sugar.at: Check m4_require's error message.
5420 * tests/base.at: Check AC_REQUIRE's error message.
5421 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5422 to...
5423 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5424 AT_CHECK_M4.
5425 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5426 `expout' as the last parameter.
5427 * tests/tools.at: Adapt to the above change.
5429 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5431 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5432 information about race-free implementations of mkdir.
5434 2006-06-04 Eric Blake <ebb9@byu.net>
5436 * bin/autoreconf.in (help): Document M4 environment variable.
5437 * bin/autoconf.as (Usage): Likewise.
5438 * bin/autom4te.in (help): Likewise.
5439 * doc/autoconf.texi (autom4te Invocation): Likewise.
5441 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5443 * NEWS: GNU make now recommended for VPATH builds.
5444 Mention that some macros are now documented to be obsolescent.
5445 * doc/autoconf.texi:
5446 Prefer "current" to "modern" to describe
5447 currently-used (albeit perhaps old-fashioned) hosts.
5448 Mention which ancient features no longer need to be worried about.
5449 setgid -> set-group-ID
5450 setuid -> set-user-ID (these are the Posix terms)
5451 Fix some misuses of "only".
5452 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5453 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5454 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5455 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5456 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5457 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5458 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5459 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5460 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5461 Mention that these macros are obsolescent.
5462 (Installation Directory Variables): shall -> should
5463 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5464 Mention that it's now safe to use 3 and 4.
5465 (Limitations of Usual Tools): cp -r is now specified by Posix.
5466 Omit longwinded and obsolescent discussion of cp -f.
5467 Modernize discussion of expr, ls.
5468 (Limitations of Make): Modernize discussion of VPATH builds.
5469 Mention $? as a workaround in some cases.
5470 * doc/install.texi (Basic Installation):
5471 Mention "./configure; make; make install" first. Be more
5472 specific about why this file is generic. Remove unnecessary
5473 parens. Remove misleading "only". Remove obsolete advice
5474 about csh. Don't say "configure" takes awhile; say it
5475 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5476 and CC=c99 rather than CC=c89, as these are blessed by current
5477 Posix. Recommend GNU make if doing a VPATH build.
5479 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5481 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5482 examples involving shell prompts.
5484 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5485 and Paul Eggert <eggert@cs.ucla.edu>
5487 * doc/autoconf.texi (Here-Documents): Add details about the
5488 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5489 use "here-documents" instead of "here documents".
5491 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5493 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5495 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5497 * doc/autoconf.texi (File System Conventions): Warn about ":"
5498 anywhere in directory names.
5500 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5502 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5503 about quoting the case statement, just in case.
5504 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5505 was fixed in ksh93g; reported by Ralf Wildenhues.
5507 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5509 * doc/autoconf.texi (System Services): Do not document
5510 overriding EXEEXT via ac_cv_exeext=ext.
5511 (Particular Programs) <AC_PROG_MKDIR_P>:
5512 Document that ${MKDIR_P} understands --.
5513 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5514 comment.
5516 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5518 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5519 argument with leading hyphen. Problem reported by Paul Eggert.
5521 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5523 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5524 about quoting ac_try: quote all of it, if any of it seems suspicious.
5525 This means we don't have to worry about ${ or sed any more.
5526 Also, double-quote the case statement, to work around misuses via
5527 underquoting as reported by Ralf Wildenhues in
5528 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5529 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5530 undocumented and dangerous macro.
5531 Problem reported by Ralf Wildenhues in
5532 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5534 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5536 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5537 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5538 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5540 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5542 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5543 since evidently some packages rely on the old, broken behavior.
5544 Problem reported by Ralf Wildenhues in
5545 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5546 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5547 pre-2006-05-26 definitions, but leave in the comments that
5548 these macros are dangerous and should not be used.
5549 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5550 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5551 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5552 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5553 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5555 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5557 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5558 the use of 'tr', since this is our only use of 'tr'.
5560 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5561 and Paul Eggert <eggert@cs.ucla.edu>
5563 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5564 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5566 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5568 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5569 the output file in the `${datarootdir}' test.
5571 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5572 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5574 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5575 mention of `datarootdir' in the input file(s), but literal
5576 `${datarootdir}' in the output file, and we haven't warned yet,
5577 then warn as well: the user may have (erroneously) used
5578 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5579 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5580 * tests/torture.at (datarootdir workaround): Extend this test.
5581 * NEWS: Update.
5583 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5584 and Paul Eggert <eggert@cs.ucla.edu>
5586 * doc/autoconf.texi (autoheader Invocation): The first argument to
5587 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5588 alternatives and clear up the language a bit.
5590 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5592 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5593 ac_config_guess, ac_config_sub, ac_configure.
5594 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5595 Fix typo that prevented an unnecessary space from being removed.
5596 Problems reported by Ralf Wildenhues in:
5597 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5599 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5601 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5602 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5603 Don't use the term "thread-safe" to talk about mkdir race
5604 conditions, since the problem is more a process than a thread
5605 issue. Problem reported by Stepan Kasal in:
5606 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5607 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5608 the test for 'install' more closely. Look at MKDIR_P first.
5609 Look in the PATH, and at /opt/sfw/bin.
5610 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5611 Don't bother to try mkdir -p, since we already check mkdir --version;
5612 just look at the version number. (There's no easy way to check
5613 for race-free implementations.)
5614 * tests/tools.at (autoconf: subdirectories): Adjust to above
5615 changes, since MKDIR_P now might end in "/mkdir -p".
5617 * doc/autoconf.texi (autoheader Invocation): Mention that the
5618 first arg of AC_DEFINE_UNQUOTED must be a literal.
5619 Problem reported by Ben Pfaff in
5620 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5622 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5623 * doc/autoconf.texi (Special Chars in Variables): New section.
5624 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5625 (Installation Directory Variables): Quote $(datadir) better.
5626 (Limitations of Builtins): Describe some of eval's trickiness.
5628 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5629 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5630 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5631 in front of every arg, not just trailing args. Quote apostrophes.
5632 (_AC_EVAL_ECHO): New macro.
5633 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5634 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5635 removed.
5636 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5637 exposed by quoting of eval argument. Put the command on line line
5638 so it logs better.
5639 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5640 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5641 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5642 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5643 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5644 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5645 Use eval more safely.
5646 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5647 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5648 to be replaced.
5649 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5650 lines, exposed by quoting of eval argument.
5652 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5653 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5655 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5656 initialization of `ac_cv_exeext', do not override it if it was
5657 already set, unless it was set to `no', for compatibility with
5658 Autoconf-2.13, and comment this.
5659 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5660 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5661 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5662 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5663 Document that this test may be overridden by setting
5664 `ac_cv_exeext'.
5666 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5668 Revert these two patches:
5670 2006-04-06 Eric Blake <ebb9@byu.net>
5671 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5672 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5673 2006-04-01.
5675 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5676 Clean up _AC_COMPILER_EXEEXT* macros.
5677 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5678 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5679 ac_file to the name of the default output file and call
5680 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5681 initial `rm' of the candidate files...
5682 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5683 the same list in subsequent `rm' calls, and for the temporary
5684 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5685 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5686 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5687 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5688 no longer needed) by libtool. Make it a cache check.
5689 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5690 copied here by mistake.
5691 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5692 _AC_COMPILER_EXEEXT.
5693 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5694 _AC_COMPILER_OBJEXT directly.
5695 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5697 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5699 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5700 Fix description of how the buggy `sed' works.
5702 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5704 Sync from Automake:
5706 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5707 ENOLCK. Only mention `make -j' when applicable. Only raise
5708 fatal errors when `make -j' is involved. Improve error message.
5710 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5712 * doc/autoconf.texi (Here-Documents): We now know more about
5713 the variable expansion in here documents bug.
5714 Thanks to Tim Rice and Stepan Kasal.
5716 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5717 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5719 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5721 * tests/autotest.at (Multiline command from M4 expansion):
5722 No failure to be expected if the shell quotes newlines in
5723 commands in the `set -x' output. Report by Tim Rice.
5724 * THANKS: Update.
5726 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5728 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5729 expansion in the here-documents used by config.status, as that
5730 runs afoul of the Korn shell version M-12/28/93d bug described in
5731 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5732 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5733 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5735 2006-05-23 Jim Meyering <jim@meyering.net>
5737 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5738 Fix typo introduced with 2006-04-02 change. It reversed the sense
5739 of the test.
5741 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5743 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5744 ac_dB slightly, to save bytes in the script.
5745 Max out at 50 lines, rather than 96; this is more likely
5746 (though not guaranteed) to avoid obscure 'sed' failures.
5748 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5750 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5751 `tr -d -' as bad option argument. Work around this by deleting
5752 an unrelated character.
5753 Report by Tim Rice <tim@multitalents.net>.
5755 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5756 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5757 Stepan Kasal <kasal@ucw.cz>
5759 * doc/autoconf.texi (Particular Programs): Do not promise that
5760 we always prefer the GNU version of the program, and that we
5761 search according to PATH; both rules can have exceptions.
5762 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5763 AC_PROG_SED. Move descriptions of limitations
5764 to the Limitations of Usual Tools section.
5765 (Limitations of Usual Tools) <sed>: Mention script length
5766 limitations with Solaris /usr/ucb/sed.
5767 <grep>: Fix wording for empty alternative. Mention that -c and
5768 -l should not be combined, and that -E and -F should not be
5769 combined.
5771 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5772 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5774 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5775 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5777 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5779 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5780 AC_DEFINE is now passed to m4_pattern_allow.
5781 * NEWS: Mention that; likewise for AC_SUBST.
5782 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5783 the parameter to m4_pattern_allow.
5784 * tests/tools.at: Add a check for that.
5786 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5788 * lib/autoconf/status.m4: Fix typos.
5790 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5792 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5793 only the files that this macro generates.
5795 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5797 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5798 the HP-UX sed limitation of 99 commands, labels do not count.
5799 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5800 in the comment.
5801 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5803 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5805 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5806 Import the following fix from coreutils:
5808 2006-01-13 Jim Meyering <jim@meyering.net>
5810 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5811 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5812 not double-quote uses of that variable, to accommodate the rare
5813 case in which getmntent is available in none of the libraries
5814 checked. This happens at least on FreeBSD 5.0.
5816 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5818 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5819 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5820 some other programs unwisely rely on these undocumented vars.
5821 But put in warning comments about them.
5822 Problem reported by Ralf Wildenhues in
5823 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5824 * NEWS: Document that these variables are intended to go away.
5826 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5828 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5829 and set the language to C++ (analogous to the equivalent Fortran
5830 tests).
5832 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5833 * doc/autoconf.texi (C++ Compiler): Document it.
5834 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5835 * NEWS: Update.
5837 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5839 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5840 that caused config.status to generate 100-command sed scripts; the
5841 portable limit is 99.
5843 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5845 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5846 variable `ac_d' instead of `d' to avoid infringing namespace.
5847 Report by Ralf Menzel.
5849 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5851 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5852 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5853 * tests/tools.at (autoconf: subdirectories): New test, taken from
5854 the corresponding problem report by Ralf Wildenhues in:
5855 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5857 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5858 Quote some uses of shell variables if they might suffer unexpected
5859 globbing. This doesn't fix all instances of quoting problems that
5860 I found, just the easy ones that look safe.
5861 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5862 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5863 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5864 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5865 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5866 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5867 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5868 Likewise.
5869 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5870 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5872 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5874 * bin/autoreconf.in ($help): Reword according to the manual.
5875 Suggested by Olly Betts.
5877 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5878 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5880 * bin/autoreconf.in: Pass the directory argument to
5881 `require_configure_ac'. Fix comment.
5882 * tests/torture.at (Configuring subdirectories): Expose this.
5883 Reported by Olly Betts.
5885 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5887 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5888 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5889 Automake as follows:
5891 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5892 `$configure_in' instead of `configure.in', to preserve
5893 directory component.
5895 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5897 * config/config.guess, config/config.sub, config/texinfo.tex,
5898 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5900 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5902 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5903 test for C99 conformance; (bool) 0.5 is an integer constant
5904 expression, but (bool) -0.5 is not. Problem reported by Fedor
5905 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5907 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5909 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5910 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5911 Warn about obsolete install-sh files. Remove stray sentence
5912 fragment and fix cross reference.
5913 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5914 install -d; this undoes the 2006-05-10 change.
5915 (MKDIR_P): Mark with AN_MAKEVAR.
5916 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5917 that we don't require $INSTALL to be thread-safe. Move comments
5918 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5919 of AC_PROG_INSTALL. Output a message saying that we're checking
5920 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5921 MKDIR_P instead of AC_SUBST.
5922 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5923 Special magic for MKDIR_P, too.
5924 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5925 a dnl.
5926 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5928 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5930 Sync from Automake, as follows:
5932 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5933 * config/install-sh: Initialize IFS, so field splitting isn't
5934 turned off later.
5935 * config/mkinstalldirs: Likewise.
5936 * config/missing: Remove superfluous quotes. Replace all uses of
5937 `[' by `test', for consistency, and for..
5938 * config/missing (sed_minuso, sed_output): New variables.
5939 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5940 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5941 Fixes `missing' to detect `--output' for help2man. Fixes
5942 PR automake/483. Report by Dennis J. Linse.
5943 (autom4te): Document in `missing --help'.
5945 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5947 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5948 * config/install-sh: Don't use 'path' to talk about file names,
5949 as per GNU coding standards. Close a race condition reported by Ralf
5950 Wildenhues and Stepan Kasal. There is still a race condition
5951 on hosts that predate Posix 1003.1-1992, but we can't help this.
5952 Don't mishandle weird characters like space on pre-Posix hosts.
5953 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5954 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5955 AC_PROG_MKDIR_P from AS_MKDIR_P.
5956 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5957 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5958 earlier editions are not (including Automake 1.8.3).
5959 Do not suggest mkinstalldirs for thread-safety.
5960 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5961 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5962 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5963 presence of special characters and race conditions.
5964 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5965 in Autoconf's name space.
5967 2006-05-10 Bruno Haible <bruno@clisp.org>
5968 and Paul Eggert <eggert@cs.ucla.edu>
5970 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5971 from Automake with minor changes.
5972 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5974 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5976 * config/install-sh: Update to Automake CVS version, as follows:
5977 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5978 * lib/install-sh: Simplify the expr implementation of dirname.
5979 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5980 * lib/install-sh: Handle --, and diagnose unknown options.
5982 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5984 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5985 `./autom4te' to create `./testsuite', since the `all' target
5986 will ensure its presence, but `installcheck' should not create
5987 the uninstalled wrappers.
5989 * tests/torture.at (Unusual Automake input files): Skip if we
5990 detect automake < 1.8.
5992 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5994 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5995 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5996 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5997 * NEWS: Update.
5999 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6001 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6002 munge (multiple) white space and other oddities.
6003 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6004 single quotes in variable assignment.
6005 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6006 and similar failures by adding multiple spaces, tabs, and other
6007 special characters.
6008 Report and different test suggested by Francesco Romani
6009 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6011 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6012 single quotes, we only need to search for single quotes; this
6013 both simplifies the search pattern, and makes us less
6014 susceptible to `echo' variations for arguments not containing
6015 single quotes.
6016 (_AC_ARG_VAR_VALIDATE): Likewise.
6018 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6020 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6021 `$*' and IFS concatenation issue with traditional shells and
6022 bash-2.04. Report by Seanster@Seanster.com.
6024 2006-05-03 Bruno Haible <bruno@clisp.org>
6026 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6027 precisely which Mac OS X versions have the od problem.
6029 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6031 * doc/autoconf.texi: Use @option systematically.
6033 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6034 and Bruno Haible <bruno@clisp.org>
6036 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6037 about 'od'.
6038 (Integer Overflow): Mention the special case of integer division
6039 overflow.
6041 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6043 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6044 traditional shells like the Solaris one that do not use the
6045 first IFS character for assembling `$*'.
6046 Prompted by a related report from autoconf_bug@nro.ca.

6102 * bin/autoconf.as (me): Replace by as_me.
6104 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6106 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6107 since as_me isn't set yet.
6109 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6111 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6112 a few minor bugs in this area.
6114 * doc/autoconf.texi (Programming in M4sh): Comment out the
6115 documentation of AS_BASENAME, for now.
6116 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6117 (Limitations of Builtins) <basename>: Do not refer to
6118 AS_BASENAME.
6119 * bin/autoconf.as (me): Don't use AS_BASENAME.
6120 (dir): Remove the unused variable.
6121 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

6141 * lib/autoconf/general.m4: Likewise.
6142 * lib/autoconf/headers.m4: Likewise.
6144 * doc/autoconf.texi (Run Time): Document the exit status situation
6145 with more accuracy and detail.
6147 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6149 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6150 Archive is not officially `GNU' any more. Update URL.
6151 (Defining Directories): Likewise
6152 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6154 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6156 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6157 newline from the `trap' code to finish `config.log'; the NetBSD
6158 /bin/sh resets the exit status after an empty command, as
6159 documented in doc/autoconf.texi.
6160 Reported by Dalibor Topic <robilad@kaffe.org>.
6162 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6164 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6165 Suggested by Bruno Haible.
6167 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6169 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6170 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6171 Instead, just list the shells that we know work.
6172 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6173 changed. Be more cautious about the _cv_ variable.
6174 * tests/tools.at (Syntax of the shell scripts): Check the
6175 _cv_ variable once, at first, to avoid an internal autoconf error
6176 when sh -n does not work.
6178 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6180 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6182 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6184 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6185 use ">&-" since we're only 99.999% sure that this is portable,
6186 and since the MinGW bug is fixed in a different way.
6187 * lib/autotest/general.m4 (AT_INIT): Likewise.
6189 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6191 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6192 before opening config.log, to avoid hitting a bug on MinGW.
6194 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6196 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6197 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6198 This works around a MinGW bug reported by Eric Paire.
6199 Make sure that all writes to the log file append to it,
6200 rather than possibly losing data.
6201 * lib/autotest/general.m4 (AT_INIT): Likewise.
6203 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6205 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6206 description.
6208 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6210 * NEWS: Update.
6212 * configure.ac (AC_INIT): Bump to 2.59d.
6214 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6216 Version 2.59c.
6218 * Makefile.maint (news-date-check): Do not require a leading `*'
6219 before the release date in NEWS.
6221 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6222 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6224 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6225 the instantiated file do not contain the string 'datarootdir'
6226 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6227 @mandir@, replace the reference '${datarootdir}' by the value.
6228 * tests/torture.at (datarootdir workaround): New test.
6229 * NEWS: Advertise this temporary fixup.
6230 Based on a patch by Bruno Haible, reported and analyzed by
6231 Paul Eggert and Noah Misch.
6233 2006-04-12 Eric Blake <ebb9@byu.net>
6235 * tests/autotest.at (Debugging a failed test): Fix comment.
6237 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6239 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6240 all the changes since 2006-04-07.
6242 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6244 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6245 succeeded, but `ln -s file dir' failed, take care to remove the
6246 leftover target before the next test, to prevent its spurious
6247 failure; also make sure `ln file dir' works before selecting it.
6248 Thanks to Keith Marshall for pointing this out.
6249 * THANKS: Update.
6251 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6252 assignments in `at_debug_args', so that we put them correctly
6253 in the `run' script.
6254 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6255 Reported by Eric Blake.
6257 2006-04-11 Eric Blake <ebb9@byu.net>
6259 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6260 top-level tests after micro-suite has been run. Used in...
6261 (Debugging a successful test, Debugging script and environment),
6262 (Debugging a failed test): ...these new tests. The first of these
6263 is fixed by...
6264 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6265 macro, split out from...
6266 (AT_INIT): ...here, so that using -d also generates a run script.
6267 Document that -d inhibits top-level logging.
6268 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6269 inhibits top-level logging; debug scripts are created.
6271 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6272 check.
6273 * tests/autotest.at (Empty test, Empty check): New test to check it.
6275 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6276 from gcc.
6278 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6280 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6281 the files if a problem appears. Make the empty *.at files
6282 read-only, too. Proposed by Ralf Wildenhues.
6284 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6286 * config/Makefile.am: Add comment to force updated Makefile.in.
6288 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6289 space only patch to this file, this patch causes the Makefile.in
6290 files that include freeze.mk to be updated, and thus have a
6291 newer time stamp again, which in turn makes a pristine CVS
6292 checkout have correct time stamps.
6294 * Makefile.maint (cvs-sv): New macro, to be used..
6295 (config.guess-url_prefix, config.sub-url_prefix)
6296 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6297 point to CVS text checkout of Gnulib files.
6298 (copyright-check): Bump current year.
6299 (announcement): Do not hard-wire `./announce-gen'.
6300 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6301 correctly.
6302 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6303 `chmod +x'.
6304 (wget_files): Update config.guess, config.sub, texinfo.tex by
6305 `wget-update', now that their URLs work again.
6307 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6309 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6310 Problem noted by Paul D. Smith.
6312 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6314 * doc/autoconf.texi: Remove unused words from word list.
6315 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6316 .x-sc_trailing_space: New files.
6318 * doc/standards.texi: Sync from gnulib.
6320 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6321 `LIBOBJDIR' as experimental.
6323 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6324 with a target directory; it's internally implemented as `cp'
6325 anyway, but since Autoconf advertises the possibility to use
6326 a target directory when LN_S is `ln -s', we need to find out.
6327 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6328 analyzed by Keith Marshall <keith.marshall@total.com>.
6330 * THANKS: Update.
6332 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6334 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6335 confdefs.h as-is. In general, if it has backslash-newline or the
6336 like, then it doesn't work either to sort or to remove empty
6337 lines.
6339 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6341 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6343 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6345 * lib/autom4te.in (Automake-preselections): Preselect
6346 _AM_SUBST_NOTMAKE.
6348 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6350 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6351 apostrophe within a single-quoted string, as this is the usual
6352 tradition and is easier to read than '"'"'. Don't rely on the
6353 shell treating "$/" like '$/'. Use a more-consistent indenting
6354 style for the trap.
6356 2006-04-09 Eric Blake <ebb9@byu.net>
6358 * tests/autotest.at (Backquote command substitution),
6359 (Multiline backquote command substitution): Remove mistaken
6360 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6361 applied...
6362 (Parenthetical command substitution, Multiline parenthetical
6363 command substitution): here.
6365 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6367 Import macros from gnulib (often changing their name).
6369 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

6381 (Pointers): Add Gnulib URL.
6382 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6383 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6384 Gnulib section.
6385 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6386 suggest a #define rather than a typedef for _Bool, and mention
6387 Gnulib rather than trying to substitute stdbool code.
6388 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6389 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6390 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

6393 headers too.
6394 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6395 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6396 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6397 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6398 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6399 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6400 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6401 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6402 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6403 (Coding Style). Don't mention m4_expand_once.
6404 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

6406 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6407 (AC_CHECK_FUNCS): Use it.
6408 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6409 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".

6411 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6412 (AC_HEADER_ASSERT): New macro.
6413 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6414 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6415 Catch a bug in an HP-UX C compiler.
6416 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6417 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6418 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

6421 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6422 New macros.
6424 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6425 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6427 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6429 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6430 of the warning introduced by the 2001-08-28 change.
6432 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6433 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6435 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6436 variables shall be overriden by the cache.
6437 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6438 that contains braces.
6440 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6442 Revert the patch from 2006-04-01 and only improve
6443 _AS_DETECT_BETTER_SHELL:
6445 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6446 skip nonexistent directories.
6447 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6448 only shell candidates which exist.
6449 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6450 * lib/autotest/general.m4 (AT_INIT): No need to give three
6451 parameters to _AS_PATH_WALK.

6465 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6466 and DUALCASE=1.
6467 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

6469 it is set.
6471 2006-04-07 Eric Blake <ebb9@byu.net>
6473 * doc/autoconf.texi (Programming in M4sh): Document that
6474 AS_MKDIR_P exits the script on failure.

6490 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6491 2006-04-01.
6493 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6494 Eric Blake <ebb9@byu.net>,
6495 Paul Eggert <eggert@cs.ucla.edu>,
6496 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6498 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6499 whether `set' quotes correctly: redirect stderr of the tested
6500 `set', and use a subshell, for Ultrix; use `sed' instead of
6501 `grep' for zsh `set' which may write binary output; match only
6502 at the beginning of a line, to avoid false positives.
6503 In order to avoid false positives by unrelated variables with
6504 multiline content, put the dump algorithm in a subshell and
6505 unset all variables containing newlines (except some which are
6506 special to the shell). Warn about cache variables that are
6507 unset.
6509 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6511 * config/config.guess, config/config.sub, config/texinfo.tex:
6512 Sync from upstream.
6514 * tests/mktests.sh: Reword comments.
6516 * tests/mktests.sh: Only skip internal macros starting with
6517 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6518 Update exclusion lists for the test suite to this end:
6519 (AC_ARG_VAR): Do test this now.
6520 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6521 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6522 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6523 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6525 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6526 shell issue with double-quoted command substitutions of native
6527 commands.
6528 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6529 Marshall.
6531 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6544 <tab><space> where this makes sense.
6546 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6548 * tests/Makefile.am (maintainer-check-posix):
6549 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6551 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6552 ac_config_<foo>s again, sometimes normalized, sometimes not.
6553 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6554 (AC_CONFIG_COMMANDS): Do not do so here.
6555 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6556 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6557 2005-07-25 rewrite. Noticed by Noah Misch.
6559 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6560 _AC_PRESERVE_HELP_ORDER, ...
6561 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6563 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6564 inside m4_expand_once; it is redundant.
6566 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6567 for --help from Cygnus `configure.'
6569 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6571 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6572 on a patch proposed by Ralf Wildenhues.

6582 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6583 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6584 * doc/autoconf.texi (Help Formatting): New node.
6585 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6587 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6589 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6590 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6591 lib/autoconf/types.m4, lib/autotest/general.m4,
6592 tests/mktests.sh, tests/torture.at: White space cleanup:
6593 remove some SPACE before TAB, or add quoting ('' or @&t@).
6595 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6597 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6599 2006-04-05 Eric Blake <ebb9@byu.net>

6602 empty test suite works.
6603 * tests/autotest.at (Empty test suite): Remove xfail.
6605 2006-04-05 Noah Misch <noah@cs.caltech.edu>

6608 TAGS to ac_config_<foo>s.
6609 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6610 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6611 normalizing it, consistent it with previous releases.
6612 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6614 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6616 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6617 Use simplified args that Eric Blake originally suggested.
6619 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6621 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6622 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6623 Use 'comm' rather than N instances of grep; this also fixes a bug
6624 whereby substrings were incorrectly matched, causing us to not
6625 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6626 (exclude_list): Exclude empty macros.
6627 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6629 Use awk rather than grep -E or egrep, to avoid
6630 portability problems with regular expressions containing newlines.

6632 Switch from grep to awk syntax.
6633 (ac_exclude_script): Renamed from ac_exclude_egrep.
6634 (au_exclude_script): Renamed from au_exclude_egrep.
6636 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6638 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6639 a subdirectory subject to Cygnus `configure'.
6640 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6642 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6643 report request when we have no AC_PACKAGE_BUGREPORT.
6645 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6647 * THANKS: Update.

6650 generated files.
6652 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6653 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6654 typedef'ed restricted pointer, to catch a compiler bug on
6655 HP-UX 11.x, and fix warnings so it passes with -Werror.
6656 (_AC_PROG_CC_C99): Likewise.
6657 Reported by Albert Chin <china@thewrittenword.com>.

6675 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6677 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6678 to log, point to testsuite output tree.
6680 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

6708 Clean up _AC_COMPILER_EXEEXT* macros.
6710 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6711 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6712 ac_file to the name of the default output file and call
6713 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6714 initial `rm' of the candidate files...
6715 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6716 the same list in subsequent `rm' calls, and for the temporary
6717 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6718 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6719 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6720 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6721 no longer needed) by libtool. Make it a cache check.
6722 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6723 copied here by mistake.
6724 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6725 _AC_COMPILER_EXEEXT.
6726 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6727 _AC_COMPILER_OBJEXT directly.

6759 Autoconf version number despite a zero- or one-argument AC_INIT.
6761 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6762 subordinate tools.
6763 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6764 * doc/autoconf.texi (autoreconf Invocation): Document it.
6766 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6767 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

6773 rm failed to remove it.
6775 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6777 * bin/autoupdate.in: Redefine m4_location so that warnings print
6778 the correct lines of the input file by subtracting..
6779 (_au__first_line): ..this new definition.
6781 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6782 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6783 Remove stray newline in output.
6784 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6785 AC_DEFUN this for autoconf, including the obsoletion diagnose.

6792 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6793 hairy details.
6794 The AC_LANG_SAVE issue was reported against Libtool by
6795 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6796 Kristian Kvilekval <kris@cs.ucsb.edu>.
6798 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6800 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6801 switch all of them on and of when necessary. Fixes the bug when
6802 m4sugar macros (e.g., m4_define) were expanded after the first
6803 automatic update (e.g., after AC_PREREQ or AC_INIT).

6852 * bin/autoscan.in: The value of find_configure_ac should be
6853 checked for existence, so we don't barf over a nonexisting
6854 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
6856 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6858 * bin/autoupdate.in: Fix some typos.
6860 2006-03-21 Stepan Kasal <kasal@ucw.cz>

6919 that the same works when cross-compiling.
6920 * tests/semantics.at (AC_CHECK_ALIGNOF, AC_CHECK_ALIGNOF struct):
6921 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

7439 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7441 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
7442 Factor functionality to..
7443 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7444 `AC_SUBST($1)' in the public version.
7445 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7446 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
7447 ac_pt_* variables.
7449 2005-11-01 Stepan Kasal <kasal@ucw.cz>
7451 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
7452 filesystems.
7454 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7456 * NEWS: Move AH_HEADER mention to right place.
7458 2005-10-27 Stepan Kasal <kasal@ucw.cz>
7460 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
7461 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7463 2005-10-25 Stepan Kasal <kasal@ucw.cz>
7465 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
7466 conftst2.$ac_objext.
7467 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7469 2005-10-24 Stepan Kasal <kasal@ucw.cz>
7471 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7472 conftest.o, to see whether the compiler really obeys; rm the object
7473 file before and after the test and register it with ac_clean_files.
7474 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7476 2005-10-21 Stepan Kasal <kasal@ucw.cz>
7478 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
7479 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
7480 code so that the most common case requires less forks.
7482 2005-10-20 Stepan Kasal <kasal@ucw.cz>
7484 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is

7487 * NEWS: Fix an old typo.
7489 2005-10-20 Jim Meyering <jim@meyering.net>
7491 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
7492 the latter'', in two places.
7494 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7496 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7497 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7498 the inner workings of AC_LANG_FUNC_LINK_TRY.
7499 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7500 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7501 by the function rather than ignoring it.
7502 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7503 comparing its address. Intel's interprocedural optimization was
7504 outsmarting the old heuristic. Problem reported by
7505 Mikulas Patocka.
7507 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7509 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7511 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7513 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7514 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7516 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7518 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7519 before removing it (chmod -R u+rwx); there are three instances of this.
7521 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7522 Stepan Kasal <kasal@ucw.cz>
7524 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7525 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7526 make its content writable before removing it. Remove an errorneous
7527 comment from the end, where the logs of the failed tests are copied
7528 to the main log file.
7530 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7532 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7533 in case the computer is too quick. Double quote the configure.ac
7534 snippets.
7536 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7537 problems if the testsuite were running too fast.
7539 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7541 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7542 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7543 (which belong to Xt, not X itself). See Debian bug 327655.
7544 * NEWS: Mention this.
7546 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7548 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7550 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7552 * config/move-if-change: Don't output "$2 is unchanged";
7553 suggested by Ben Elliston. Handle weird characters correctly.
7555 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7557 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7558 calls, so that the final expansion of this macro is shorter.
7559 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7560 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7561 the cleanup there. Use AS_VAR_* macros, to be more general.
7562 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7564 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7566 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7568 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7570 * doc/autoconf.texi (Configuration Headers): Add an index entry
7571 for AH_HEADER.
7573 2005-08-26 Pavel Roskin <proski@gnu.org>
7575 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7576 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7577 running xmkmf.
7579 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7581 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7582 The previous patch didn't work, so try a better one.
7584 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7586 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7587 in the example. Reported by Bruno Haible.
7588 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7589 "if $undefined_var;" succeeds with my shell.
7591 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7592 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7593 but change the m4_divert_text to m4_divert_once.
7595 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7597 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7598 Work around bug in Solaris /usr/xpg4/bin/awk.
7599 The bug is present in at least Solaris 8 through 10.
7601 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7603 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7604 some evil values and relying on the fact that $* concatenates the
7605 parameters by the first character from IFS.
7607 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7608 Stepan Kasal <kasal@ucw.cz>
7610 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7611 first header appears, define AH_HEADER.
7612 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7613 Update limitations about when to call AC_CONFIG_HEADERS.
7614 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7615 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7616 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7617 ``Configuration Actions''; fix their index entries.
7619 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7620 options correctly. Process N-M as M-N if M is smaller than N.
7621 Process ranges correctly so that N-N will run only N.
7622 Sort and uniquify the tests that will be run. If there is more
7623 than one test, reinsert the banners for the tests.
7624 * tests/autotest.at (Keywords): Unmark XFAIL.
7626 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7628 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7629 before passing the macro name to AH_TEMPLATE.
7631 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7632 now opens log after option processing; in particular, --version
7633 and --help do not touch config.log.
7635 * Makefile.maint: Revert the change from 2005-08-12.
7637 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7639 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7640 common code to...
7641 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7643 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7645 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7646 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7647 Language cleanup.
7649 * doc/autoconf.texi (Defining Symbols, Changed Results):
7650 Prepend to LIBS, not append, in examples.
7652 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7654 When building in place, set srcdir="."; suggested by Tim Van Holder.
7656 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7657 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7658 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7659 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7660 does not mean "no --srcdir option".
7662 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7664 * tests/autoscan.at (autoscan): New file.
7665 * tests/suite.at: Use it.
7666 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7667 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7669 * tests/autotest.at (Keywords): Test keywords combinations.
7671 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7673 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7674 add "2>&1"; gzip 1.2.4 prints help on stderr.
7676 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7678 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7679 was pushdef'ed twice while popped only once. Push it only once.
7680 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7682 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7684 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7685 prefixed by mere "===", not "configure: === ".
7687 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7689 * Makefile.maint: Update from Bison.
7691 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7692 "<tab>" in comment, so that the point is understandable.
7694 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7696 Rewrite substantial part of lib/autoconf/status.m4.
7697 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7698 and CONFIG_COMMANDS are not processed in four separate loops.
7699 Instead, there is one main loop. This alows that the common code
7700 is expanded only once, thus config.status (and configure) is smaller.
7702 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7703 the AC_LIST_FILES and cousins macros are no longer used.
7705 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7706 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7707 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7708 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7709 contain the initialization, nor the for loop, nor the associated
7710 commands; all these go to ...
7711 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7712 _AC_OUTPUT_CONFIG_STATUS.
7713 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7714 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7715 (_AC_OUTPUT_FILE): The creation of the sed script ...
7716 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7717 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7718 _AC_OUTPUT_MAIN_LOOP.
7719 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7720 _AC_CONFIG_COMMANDS): Use ...
7721 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7722 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7723 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7724 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7725 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7726 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7727 ... new macros.
7728 (_AC_CONFIG_UNIQUE): Update.
7729 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7730 Replaced by this ...
7731 (_AC_LIST_TAGS): ... new common macro.
7732 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7733 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7734 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7735 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7736 this didn't belong to the `config commands' section.
7737 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7738 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7739 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7740 to the `config commands' section either.
7741 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7742 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7744 ... and many changes to the comments nearby.
7746 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7747 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7748 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7749 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7750 (#define header templates): The comment at the top of the generated
7751 header now includes the name(s) of the source file(s).
7753 Several unrelated small changes:
7755 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7756 parameter to AC_DIAGNOSE.
7757 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7758 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7759 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7760 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7761 with AU::AC_OUTPUT.
7762 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7763 in AC_OUTPUT doesn't double-quote it either.
7764 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7765 parameters.
7767 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7769 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7770 versions of Portland Group compiler produce single- and double-quoted
7771 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7772 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7774 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7776 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7777 This is a corrected version of yesterday's patch.
7779 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7781 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7782 path, too; insert a "===" to emphasize the line.
7784 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7785 ac_cv_build_alias to ac_build_alias.
7786 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7788 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7789 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7790 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7791 (AC_ARG_VAR): ... here.
7792 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7793 target_alias.
7795 Keep a list of all precious variables and process them with one simple
7796 for loop, instead of expanding all commands, or, OTOH, complicated
7797 processing of output of "set".
7798 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7799 variable names in new macro...
7800 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7801 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7802 a loop to assign all ac_env_* and ac_cv_env_* variables.
7803 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7804 to INIT_PREPARE.
7805 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7806 its value to shell variable ac_precious_vars and call
7807 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7808 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7809 _AC_ARG_VAR_VALIDATE.
7811 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7812 and the AC_SUBSTs ...
7813 (AC_INIT): ... here.
7815 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
7816 the ac_subst_files section in config.log.
7818 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
7820 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
7822 * NEWS: New macro AC_C_TYPEOF.
7823 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.
7824 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
7825 * tests/c.at (C keywords): Test AC_C_TYPEOF.
7827 Fix problems reported by Nicolas Joly.
7828 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
7829 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7830 They are generated by the Tru64 v5.1B shell.
7832 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7834 Fix my changes from 2005-07-01; reported by Noah Misch.
7835 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7836 description, the macro now accepts only a single tag.
7837 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7839 Fix cases when the varsions of Autoconf and Autotest don't match.
7840 Reported by Noah Misch.
7841 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7842 at_top_builddir, for compatibility with older autotest.
7843 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7844 is not set, use at_top_builddir, for compatibility with older
7845 versions of autoconf.
7847 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7849 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7850 Problem reported by Patrick Welche.
7852 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7854 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7855 sed substitution command, so that we allow | in program prefixes
7856 and program suffixes. (& is a problem anyway; we're not fixing
7857 that here.)
7858 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7859 configure_input, top_builddir, srcdir, etc.

7871 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7891 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
7893 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7894 document to output the default config_* lists to config.status.
7895 Don't recognize option --file, if the functionality is not there.
7896 Likewise for --header; moreover, recognize --he and --h as shortcuts
7897 for --help in that case.
7899 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7900 matches the order of execution. No code changed.

7922 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7923 (AC_SUBST): Call it.
7924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7925 the directory specific variables; but don't call it for configure_input.
7927 2005-06-28 Derek Price <derek@ximbiot.com>
7929 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7930 addition.
7932 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7934 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7935 directory have inherent problems with special characters like spaces,
7936 due to limitations in Make syntax. Problem reported by Alexandre
7937 Duret-Lutz.
7938 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7951 from Justace Clutter.
7952 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7953 variable into diagnostic. Make the diagnostic an error, not a warning,
7954 because we really don't support spaces and suchlike in dir names.
7955 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7956 Don't worry about backslashes in srcdir; it can't happen now.
7957 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7958 Simplify ac_optarg handling.
7959 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

7969 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7970 that '\|' is not allowed in BREs; recommend using newline separated
7971 list of patterns instead of multiple -e options.
7973 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
7975 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

7981 2005-06-21 Stepan Kasal <kasal@ucw.cz>
7983 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7984 b, t, r, w commands require single space, while : cannot have any.
7985 (Special Shell Variables): Fix sed code this in the example.
7986 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7987 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7989 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7990 expand to the empty list. Don't use two pairs of m4_changequote,
7991 it's not necessary.
7993 2005-06-20 Derek Price <derek@ximbiot.com>
7995 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7997 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7999 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8000 * doc/autoconf.texi:
8001 Don't mention Solaris versions so much, if a
8002 problem is common to all extant versions of Solaris. Say "SunOS
8003 4" instead of "SunOS" for SunOS 4.
8004 (awk): Mention more of the limitations of traditional Awk.
8005 (cat): Don't talk about cat -v.
8007 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
8009 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
8010 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

8012 to be compatible with glibc strverscmp.
8013 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8015 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8016 on Mac OS X 10.4 reported by Peter O'Gorman in:
8017 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8018 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8019 Use shell builtins rather than 'expr', to work around expr bug.
8021 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8023 * doc/autoconf.texi: "filesystem" -> "file system".
8024 "behaviour" -> "behavior".

8026 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8027 as per POSIX.
8028 * lib/m4sugar/m4sh.m4: Likewise.
8029 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8030 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8032 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8033 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8034 to update the man page. That way, we don't have to check in new
8035 man pages every month.
8037 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8038 quotes and backslashes. Patch from Derek Price.

8043 AS_TR_SH.
8045 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8047 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8048 -u, since it outputs chatter if the input files are the same.
8049 Problem reported by Ralf Menzel.
8051 2005-06-08 Derek Price <derek@ximbiot.com>
8053 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8054 renaming them since they are about to be redefined anyhow.
8056 2005-06-08 Derek Price <derek@ximbiot.com>
8058 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8059 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8060 Move m4_undefine to alphabetical order.
8062 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8064 * README: Recommend GNU M4 1.4.3 or later.
8065 * doc/autoconf.texi (Introduction): Likewise.
8066 Reword to avoid some formatting glitches.
8067 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8068 Clarify explanation of HP compiler bug.
8069 Redo example output tp match current CVS snapshot.
8070 Use @example.org in email addresses when the examples
8071 might get inadvertently cut-and-pasted into user code.
8072 Remove example of autom4te usage that doesn't seem to work now.
8073 Use modern AC_INIT (except when the example is meant to be
8074 shown with Autoconf 2.13).
8075 Update ksh info for Solaris 9 and later.
8076 KB -> kB.
8077 Modernize description of Automake versions a bit.
8078 Don't claim a future version of Autoconf is near.
8079 * doc/install.texi: Reword to avoid some formatting glitches.
8081 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8083 * doc/autoconf.texi: Add [] to examples, so that the manual
8084 follows its own advice about quoting better.
8085 Reword to avoid some formatting glitches.
8086 * doc/installt.exi: Reword to avoid some formatting glitches.
8088 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8089 Tru64 ksh pattern matching bug. Reported against Libtool by
8090 Albert Chin <libtool@mlists.thewrittenword.com> and
8091 Nicolas Joly <njoly@pasteur.fr>.
8093 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8095 m4_cdr of one-member list was [[]] (one-member list containing an
8096 empty string) instead of [] (an empty list. Callers were skewed to
8097 match this misbehaviour. As a consequence of this:
8098 - m4_foreach([x], [], [foo]) expanded to `foo', while
8099 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8100 This bug has been fixed:
8102 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8103 expand to an empty string; print error msg if called without
8104 an argument list.
8105 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8106 misbehaviour; handle [] and [[]] correctly.
8108 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8110 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

8112 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8114 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8116 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8117 swallow records with more than 99 fields.
8118 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8119 parse the long line.
8121 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8123 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8124 swallow literals longer than 399. Reported by Ralf Wildenhues.
8125 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8126 to workaround this limitation.
8128 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8130 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8131 to gfortran, and make these the first two compiler names
8132 checked (following the general autoconf preference for gcc).
8134 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8136 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8137 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8138 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8140 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8142 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8143 expression of unbounded size when processing the --list
8144 option. This runs afoul of a limit of 399 bytes per regular
8145 expression on AIX. Problem reported by Ralf Wildenhues.
8147 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

8150 * doc/autoconf.texi (Particular Headers): Reword example
8151 for multiline stdbool replacement.
8152 (Setting Output Variables): Reword text a bit. Don't
8153 give all the details about |#_!!_#|.
8154 Reword description of line replacement.
8156 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8158 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8159 now contain newlines, and substituted files must be referenced on
8160 a line alone; the sed scripts to substitute them are now very
8161 different.
8162 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8163 commands can be put in a sed script portably.
8164 * doc/autoconf.texi (Setting Output Variables): Document above
8165 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8166 use of multiline substitution.

8176 * tests/local.at: Don't attempt to check for negated character
8177 classes in shell scripts. The test was too brittle.
8179 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8181 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8182 * doc/autoconf.texi (Limitations of Builtins): Document this
8183 limitation.
8185 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8187 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8188 common code; used in many places in the tree.

8195 messages when ac_unique_file is not found.
8196 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8197 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8198 commands, for consistency with AC_MSG_ERROR and such.
8200 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8202 * bin/Makefile.am: Merge the two rules for creating scripts.

8210 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8212 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8213 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8214 (ac_top_builddir): ... this ...
8215 (ac_top_build_prefix): ... to this; the old name is also kept, for
8216 backward compatibility.
8217 (ac_top_builddir_sub): New variable, without the trailing slash,
8218 always nonempty.
8219 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8220 * doc/autoconf.texi (Configuration Actions): Rename
8221 ac_top_builddir to ac_top_build_prefix.
8222 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8223 at_top_builddir to at_top_build_prefix.

8229 of confdefs.h .
8231 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8233 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8234 argument to m4_foreach. I guess it was necessary in the past,
8235 but I think it's a no-op now.
8237 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8239 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8240 ``cat <<_ACEOF'' commands to one.
8241 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8242 * lib/autoconf/status.m4: On various places, use expr instead of
8243 ``echo|sed.''
8244 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8245 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8246 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8247 a range.
8248 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8249 the wrong patterns between ``case'' and ``esac.'' The previous
8250 code had false positives.
8252 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8254 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8255 as on 2005-05-02.
8256 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8257 Mention LIBOBJDIR.

8302 enough arguments, similarly as in m4_bpatsubsts.
8304 2005-05-12 Stepan Kasal <kasal@ucw.cz>
8306 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

8312 for absolute directory names in one loop.
8313 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
8314 abbreviations of --version and --debug.
8316 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
8318 * doc/autoconf.texi (Autoconf Language): Be more precise about
8319 quoting rules. Problems noted by Stepan Kasal.
8320 Also, throughout this document, be more careful about white space.
8321 "blank", "white space", and "space" all have different meanings
8322 and we should be careful to say what we mean.
8324 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8326 Fix C++ related problems reported by Werner Lemberg.
8327 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

8333 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8335 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8337 * doc/autoconf.texi (Generic Functions): Typos.

8341 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8342 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8343 set by latest automake.
8345 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8347 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8348 outputs 0 on GNU/Linux these days.
8350 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8352 * doc/autoconf.texi (Autoconf Language): Add more description
8353 about quoting heuristics.
8354 (Limitations of Builtins): Describe "set -" problems.
8356 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8358 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8359 not newline.
8361 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8362 by AC_DEFINE; it was a mistake.
8363 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8365 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8367 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8369 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8371 * doc/autoconf.texi (External Software): Quadrigraphs are not
8372 processed correctly in AS_HELP_STRING; avoid this in the examples.
8373 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8374 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8375 comment and reduce m4_default([foo], []) to [foo].
8376 (m4_strip): Update the explanation.
8378 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8380 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8381 Remove core.conftest.* too; it's generated by Tru64 5.1.
8382 Problem reported by Jennis Pruett.
8383 * lib/autoconf/functions.m4
8384 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8385 Don't bother to remove core files; AC_RUN_IFELSE should do that
8386 for you.
8388 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8390 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8407 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8409 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8410 as well as configure.in. Problem reported by Gregorio Guidi.
8412 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8414 * doc/autoconf.texi (Particular Functions): Use gnulib's current

8425 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8427 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8428 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8430 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8432 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8433 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8434 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8435 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8436 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8438 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8440 * NEWS: The configure command now warns you if you attempt to use
8441 a directory whose name contains a special character like space,
8442 newline, or "\".
8443 * doc/autoconf.texi (Installation Directory Variables): Allow
8444 "," in file names. Do not use \@; it's not a portable regexp.
8445 * bin/Makefile.am (edit): Likewise.
8446 * lib/Makefile.am (edit): Likewise.
8447 * tests/Makefile.am (edit): Likewise.
8448 * tests/semantics.at: Likewise.

8450 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8451 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8452 * doc/autoconf.texi (File System Conventions): Warn about
8453 unportable file names.
8454 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8455 (AC_INIT): Use it.
8456 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8457 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8458 ac_pwd, and quote srcdir.
8459 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8461 * doc/autoconf.texi: Fix some systematic formatting problems.
8462 ".)" needs a following @: if not at the end of a sentence, and
8463 similarly for "!)". "etc." should be preceded by a comma.
8464 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8466 2005-03-22 Bruno Haible <bruno@clisp.org>
8468 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8469 argument is often called 'build-aux'.
8471 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8473 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8474 macro AC_TRY_LINK is obsolete.
8475 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8476 `AC_CONFIG_FILES'.
8478 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8480 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8481 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8482 from a Common Lisp's `cl'.
8483 (AC_PROG_CXX): Behave according to the documentation: don't
8484 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8485 make the variable CCC precious; use `cl.exe', not `cl'.
8487 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8488 Alexandre Duret-Lutz <adl@gnu.org>
8490 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8491 /dev/null, as "configure" shouldn't read stdin, and this insulates
8492 us from problems (e.g., when testing for "cl"). Also, do this
8493 redirection before invoking "hostname" or "uname", and keep the
8494 original input stream available via...
8495 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8496 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8497 bother with "</dev/null" since it's now done at the top of
8498 'configure'.
8499 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8500 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8501 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

8504 * tests/base.at (Input/Output): New test.
8506 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8508 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8509 newline if neither \c nor -n work, as that would output two
8510 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8512 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8514 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8515 This causes that any required macros inside will get before the if.
8516 * doc/autoconf.texi (autom4te.cache): A typo.
8518 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8520 Undo previous change, except keep the change to
8521 lib/autoconf/programs.m4 that replaced grep with shell
8522 pattern-matching. This is because net-snmp configure reads stdin.
8523 Reported by Noah Misch.
8525 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8527 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8528 from /dev/null, as "configure" shouldn't read stdin, and this
8529 insulates us from problems (e.g., when testing for "cl").
8530 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8531 before invoking "hostname" or "uname".
8532 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8533 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8534 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8535 "</dev/null" since it's now done at the top of 'configure'.
8536 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8537 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8538 Also, replace grep with shell pattern-matching, to save a process.
8540 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8542 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8543 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8544 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8545 compiler.
8547 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8549 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8550 grep -q isn't portable. Improve grep -s explanation.
8551 Problem reported by Dan Manthey.
8553 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8555 * doc/autoconf.texi (Special Shell Variables): Clarify
8556 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8558 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8560 * doc/autoconf.texi: Use @acronym for DJGPP.
8561 Fix some @code's that should have been @env's, and vice versa.
8562 Sort environment variable names.
8563 Mention that shells no longer inherit IFS.
8564 Don't recommend PATH_SEPARATOR=';' so strongly.
8565 Mention that $RANDOM might expand to the empty string.
8566 "symlink" and "soft link" -> "symbolic link".
8567 Improve mktemp description (reported by Bruno Haible).
8569 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8571 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8572 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8573 Likewise.
8574 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8575 Likewise.
8577 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8579 * NEWS: Mention AT_COPYRIGHT.
8581 * tests/local.at (AT_CMP): Use diff directly on input files rather
8582 than copying them.
8584 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8585 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8587 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8588 and Paul Eggert <eggert@cs.ucla.edu>
8590 * tests/autotest.at (Empty test suite): New test.
8591 * tests/torture.at (Substitute and define special characters)
8592 (Substitute a 2000-byte string, Define to a 2000-byte string)
8593 (Substitute a newline, Define a newline): New tests.
8595 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8597 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8598 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8599 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8600 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8601 (Standard regular expressions): New test.
8602 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8603 excess test name quoting.
8604 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8605 CPPFLAGS to `configure' instead of setting it in `configure'.
8607 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8608 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8609 on some platforms.
8611 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8612 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8614 * tests/local.at (AT_CMP): New macro.
8615 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8616 (AC_SAVE_STATE): Move environment grep...
8617 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8618 (AT_CONFIG_CMP): New macro.
8619 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8620 * tests/c.at (Extensions): Do not exit early.

8623 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8624 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8626 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8627 (AC_COPYRIGHT): Factor header comment portion out and move into...

8629 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8630 (AT_INIT): Add Autotest copyright notice. Display copyright notices in

8640 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8642 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8643 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8645 Try not to generated lines of unlimited length, as POSIX places a
8646 2047-byte limit on line length of portable text files.
8647 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8648 Use newline as a separator, not space.

8650 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8651 space.
8653 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8655 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8656 as_func_*. Add test to check whether positional parameters
8657 are restored after function return.
8659 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8661 * doc/autoconf.texi (Special Shell Variables): Mention _,
8662 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8663 if they contain a lower-case letter. The DUALCASE problem was
8664 reported by Ralf Wildenhues.
8666 * bin/autoconf.as: Don't exit with status 0 after write failure
8667 with --help or --version.
8668 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
8669 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
8671 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8673 * doc/autoconf.texi (Limitations of Usual Tools):
8674 Unicos 9 sed limitations.
8675 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
8676 to get the option-enhanced interface on older Crays. Try ftn for
8677 Fortran 95 (newer Crays).
8679 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8681 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8682 care to echo the commands, so the user knows what's going on.
8683 Modified from a suggestion by Stepan Kasal.
8685 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
8686 with a cross reference. Derived from a suggestion by Bruce Korb.
8688 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
8690 * doc/autoconf.texi (config.status Invocation): Warn about
8691 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
8692 * doc/install.texi (Defining Variables): Likewise.
8693 Based on a proposed patch by Ralf Wildenhues.
8695 * man/Makefile.am (.x.1): Make sure the required generated files
8696 are up to date. Problem and original solution proposed by Stepan Kasal.
8697 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
8698 implicit-man-prerequisites): New rules, used by the above.
8700 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
8701 * config/config.guess, config/config.sub, config/install-sh: Likewise.

8704 2005-01-29 Stepan Kasal <kasal@ucw.cz>
8706 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8707 Update the long comment explaining it.
8709 m4_require no longer writes an ``is required by'' line to the
8710 execution stack. It contains only one bit of non-redundant
8711 information: that the macro was required, not called. And even
8712 this bit is useless in most situations: have you ever met a macro
8713 which both calls and requires the same macro?
8715 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8716 (_m4_defun_pro_outer): ... only via this macro, for the outermost
8717 macro.
8718 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
8719 (m4_expansion_stack_pop): Remove the misplaced comment.
8720 (m4_require): Don't put the ``is required by'' line to the
8721 execution stack; slightly improve the out-of-a-defun error message.
8722 (_m4_divert_grow): New macro, counter for the temporary diversions.
8723 (_m4_require_call): Use it.
8724 * tests/m4sugar.at (m4_require): Expect output without the
8725 ``is required by'' messages.
8727 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8729 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8730 rather than x for expr.
8732 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8733 this is safe.
8734 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8735 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8740 2005-01-27 Akim Demaille <akim@epita.fr>
8742 Have autoheader honor --force.
8744 * doc/make-stds.texi, doc/standards.texi: Update from masters.
8745 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
8746 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
8747 from masters, so that FileUtils.pm's update_file provide --force
8748 support.
8749 * bin/autoheader.in: Pass $force to update_file so that

9135 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9136 "char c = '\200';" rather than "char c = 0x80;" as the

9218 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
9220 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9221 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9222 variants", "Unix", and some related minor wording fixups.
9224 (Shellology, Special Shell Variables): Document that the Zsh
9225 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9226 to Alexandre Duret-Lutz for this info.
9228 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>
9230 * doc/autoconf.texi (One-Shot Macros): New node.

9235 of putenv. Problem reported by Michael Wardle.
9237 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9239 * doc/autoconf.texi (auindex): New macro.
9240 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9241 Problem reported by Stepan Kasal.
9243 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
9245 Fix problems reported by Andreas Buening in:
9246 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
9247 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9248 in test makefile.
9249 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9250 readable; it's not true in OS/2-emx.
9252 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9254 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9255 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9256 (trivial change). Problem and patch reported by Andrew Church in:
9257 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9259 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
9261 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
9262 three args in examples. Problem reported by Frederik Fouvry in:
9263 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
9264 Also, fix some minor spacing and punctuation bugs.
9266 2004-09-02 Akim Demaille <akim@epita.fr>
9268 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
9269 "case" to restore ordering.
9270 Reported by Stepan Kasal.
9272 2004-08-26 Akim Demaille <akim@epita.fr>
9274 * doc/autoconf.texi: Minor typos and stylos.

9282 Version 2.59b.
9284 * README: Add advice about m4 1.4.2.
9286 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9287 texinfo.tex for now (done by hand now).
9288 * Makefile.maint (wget_files, cvs_files):
9289 Remove ansi2knr.c; nobody uses it.
9290 (ansi2knr.c-url_prefix): Remove.
9291 (cvs-update): Fix test for failure. I don't know why it ever
9292 worked...
9294 * doc/autoconf.texi: Update URLs, some of which went stale.
9295 Use @uref rather than @href.
9297 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9298 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9300 * config/config.guess, config/config.sub, config/elisp-comp,
9301 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9302 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9304 * NEWS, TODO, configure.ac, bin/autoscan.in,
9305 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
9306 doc/install.texi, lib/Autom4te/Configure_ac.pm,

9310 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9311 tests/tools.at, tests/torture.at:
9312 Use "file name" rather than "filename" or "path",
9313 to be consistent with the terminology of the GNU coding standards.
9315 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9317 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9318 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9319 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9320 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9322 More fixes to support spaces in the name of the build directory.
9323 This isn't a complete fix but it's an improvement.
9325 * bin/autoconf.as (autom4te_options): New var.
9326 Use it instead of appending to AUTOM4TE, so that we can allow
9327 spaces in the build directory's absolute name.
9328 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9329 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9330 AT_CHECK_NOESCAPE): Likewise.
9331 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9332 main program): Likewise.
9334 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9336 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
9337 From Ralf Corsepius in:
9338 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
9340 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9342 * doc/autoconf.texi (Function Portability): Document isinf and
9343 and isnan. From a suggestion by Kevin Ryde.
9345 * lib/Autom4te/General.pm (END): Return correct exit status even
9346 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9348 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9350 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9351 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9352 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9354 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9356 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9357 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9358 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9359 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9360 * lib/autom4te.in (Automake-preselections): Preselect
9361 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9363 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9365 * lib/autom4te.in (Automake-preselections): Preselect
9366 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9367 trace them.
9369 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9371 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9372 Tru64.
9373 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9374 Document problem with "`""`" in pdksh POSIX mode.
9376 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9378 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9379 with pdksh, too. Problem reported by Patrick Welche via
9380 Gary V. Vaughan.
9381 * doc/autoconf.texi (Shellology): Note that set -o posix is
9382 useful for pkdsh, too.
9384 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9386 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9387 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9388 Don't fail if ENV or BASH_ENV is readonly.
9389 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9390 etc. are read only. Problem reported by Ludovic Courtes.
9392 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9394 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9395 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9396 (trivial change)
9398 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9400 * doc/autoconf.texi (File System Conventions): Warn about
9401 names like "aux". Problem reported by Eric Blake.
9403 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9404 by zero instead of array size, so that we can use any arithmetic
9405 constant expression (instead of requiring an integer constant
9406 expression). This allows us to test expressions like DBL_MAX <
9407 LDBL_MAX, which didn't conform to the C standard using the old
9408 method.
9409 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9410 now that we can do floating-point tests at compile time.
9412 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9414 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9415 and LDBL_EPSILON, as the resulting expression isn't an
9416 integer constant expression and violates the C standard.
9417 Problem reported by Nelson H. F. Beebe. Also, check
9418 for "L" suffix, and check that long double doesn't have
9419 worse range or precision than double, that mixed-mode
9420 arithmetic doesn't generate a diagnostic, that double
9421 constants fit in long double.
9423 2004-06-03 Kevin Ryde <user42@zip.com.au>
9425 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9426 malloc(0) and realloc(NULL,size).
9428 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9429 Bob Proulx.
9431 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9433 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9434 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9435 by Jim Meyering.
9437 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9439 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9440 can be rewritten using if-then-else. Suggested by Bruno Haible.
9442 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9444 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9445 Problem reported by Stepan Kasal.
9447 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9449 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9450 change). Patch reported by Ralf Wildenhues in
9451 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9453 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9454 function F exists if the compiler and linker let you compile an
9455 expression like (F != 0). Recent versions of GCC optimize away
9456 the reference to F in that case, since every function address must
9457 be nonzero, so the link succeeds even if F does not exist.
9458 Problem reported by Manu in
9459 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9461 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9462 "Unix". Many uses changed.
9463 (Limitations of Builtins): Explain better why the ! command isn't
9464 portable.
9466 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9468 * lib/autom4te.in (Automake-preselections): Preselect
9469 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9471 2004-05-19 Kevin Ryde <user42@zip.com.au>
9473 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9474 referencing AC_FUNC_STRERROR_R.
9476 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9477 note pessimistic assumption when cross compiling.
9479 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9481 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9482 (until 2004) invoked subcommands with sh -e, contra POSIX.
9483 Reported by Kevin Ryde.
9485 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9487 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9488 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9489 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9490 `test -f " /usr/bin/grep"', which _always_ failed.
9491 (AC_PROG_SED): Ditto bogus PATH fix.
9492 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9493 requires that grep correctly supports _multiple_ `-e' options, rather
9494 than stating only that grep should accept `-e'.
9496 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9498 Port to C99, which requires that 'exit' be declared.
9500 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9501 to ensure that stdlib.h is included.
9502 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9503 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9504 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9505 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9506 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9507 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9508 when using 'exit' in a test; C99 requires that 'exit' be declared.
9510 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9512 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9513 now prefers 'grep' implementations that accept -e.
9514 (Limitations of Usual Tools): Describe problems of traditional
9515 egrep and fgrep with long input lines, and of traditional grep
9516 with -e.
9517 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9518 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9519 All callers changed. Append /usr/xpg4/bin to the PATH, for
9520 Solaris.
9521 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9522 the user with complaints about multiple -e options.
9523 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9524 Define it with AC_PROG_GREP.
9525 * configure.ac (AC_PROG_GREP): Add.
9526 * lib/freeze.mk (GREP): New macro.
9528 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9530 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9531 a possible candidate only after all others fail, rather than
9532 consulting it first. This improves backward compatibility by
9533 better reflecting the way shell selection occurred in previous
9534 versions of Autoconf, and should help to avoid triggering latent
9535 problems in other packages, such as the one in Automake where zsh
9536 is not handled robustly:
9537 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9538 Although it is not Autoconf's responsibility to work around
9539 problems in Automake, it nevertheless makes sense to avoid
9540 introducing unnecessary incompatibilites.
9542 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9543 Gary V. Vaughan <gary@gnu.org>
9545 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9546 how deeply nested we are when a suitable tool is found, set the
9547 ac_path_TOOL_found flag.
9548 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9549 nested we are in this macro. Break out of all 3 nested loops if
9550 ac_path_TOOL_found is set.
9552 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9554 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9555 of the _AS_PATH_WALK loop too if GNU flavor is found.
9557 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9559 * doc/autoconf.texi (Limitations of Make): Update documentation
9560 for `$<'. New entry `Long lines', based on a report from Simon
9561 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9562 paragraph about DJGPP, based on a mail from Richard Dawe.
9564 2004-04-20 Paul Eggert <eggert@twinsun.com>
9566 * tests/c.at (C keywords): Don't assume that GCC supports
9567 "restrict" and "inline", as sufficiently-old GCC versions do not
9568 (also, GCC configured to be in pedantic C89 mode does not).
9569 Problem reported by Sumit Pandya in:
9570 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9572 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9573 consider -g to work if it generates warnings when plain compiles
9574 don't. Problem reported by Braden McDaniel in:
9575 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9577 * doc/autoconf.texi (Slashes): New section, to document a problem
9578 reported by Jim Meyering in:
9579 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9581 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9582 linker output files before linking, to work around IRIX 6 linker bug.
9583 Problem reported by Rainer Orth in:
9584 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9586 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9588 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9589 best tool so far counter rely on the tool path variable name to
9590 avoid checks for one tool being affected by the results of running
9591 the length check on a previous tool.
9593 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9594 match expression argument, as different greps have different
9595 regular expression flavours.
9596 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9597 literals.
9598 (AC_PROG_EGREP): Pass 'EGREP$'.
9599 (AC_PROG_GREP): Pass 'GREP$'.
9601 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9603 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9604 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9606 2004-03-29 Paul Eggert <eggert@twinsun.com>
9608 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9609 Types, Specific Compiler Characteristics, System Services,
9610 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9611 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9612 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9613 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9614 Likewise.
9615 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9616 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9617 AC_TYPE_OFF_T): Likewise.
9618 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9619 Likewise.
9621 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9622 pacify libtool 1.5.2. Fix quoting problems in sed command.
9624 2004-03-28 Paul Eggert <eggert@twinsun.com>
9626 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9627 now defines HAVE_DECL_TZNAME if it is declared, when
9628 HAVE_STRUCT_TM_TM_ZONE is not defined.
9629 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9630 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9631 for HAVE_TZNAME.
9633 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9635 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9636 superfluous backslashing of quotes (") in sed expressions;
9637 thanks to Paul Eggert.
9639 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9641 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9642 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9643 H. F. Beebe for the bug report.
9645 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9647 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9648 quoted -cmdline argument in Portland Group compiler (bug
9649 reported by Jeffrey J. Barteet).
9651 2004-03-25 Kevin Ryde <user42@zip.com.au>
9653 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9654 (Run Time): ... here, where it's now mentioned.
9656 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
9658 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9659 inherits from language Autoconf-without-aclocal-m4.
9660 (Customizing autom4te): Adjust example; the cache must now be
9661 disabled for language Autoconf-without-aclocal-m4.

9675 AC_CHECK_TOOLS.
9676 (Specifying Names): Document the reason for these future
9677 behavioral changes.
9678 * tests/mktests.sh: Do not generate tests for the
9679 new macros.
9680 * NEWS: Document these changes.
9682 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9683 they make TeX hang up.
9685 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9687 * NEWS: New macro AC_CHECK_ALIGNOF.
9688 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9689 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9690 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9691 vowel.
9692 (AC_CHECK_ALIGNOF): New macro.
9693 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9694 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9695 those for sizeof.
9697 2004-03-03 Paul Eggert <eggert@twinsun.com>
9699 * bin/Makefile.am (edit): Don't use $< in a context where
9700 POSIX doesn't require support for it. Use $@.in instead.
9701 Problem reported by Anthony N. Frasso in
9702 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9703 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9705 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9707 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9708 from the next generation of Libtool.
9709 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9711 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9713 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9714 is not always thread-safe. Report from Nathanael Nerode.
9716 2004-02-18 Paul Eggert <eggert@twinsun.com>
9718 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9719 problem on QNX reported by Stephen Rasku in
9720 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9722 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9723 $(m4sh_m4f_dependencies); this removes a FIXME.
9724 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9725 (MAINTAINERCLEANFILES): Split into pieces,
9726 one per related section. Add $(srcdir)/wrapper.in.
9728 2004-02-09 Paul Eggert <eggert@twinsun.com>
9730 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9731 AC_SUBST provides no portable way to escape literal newlines.
9733 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9734 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9735 Darwin uses -lcrt2.o and there's little point to cataloging all
9736 the system variants. Partial fix reported by Andreas Waechter in:
9737 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9738 for bug reported by Nelson H. F. Beebe in:

9744 suggested by Paul Eggert.
9745 * lib/autoconf/autoupdate.m4: Correct reference to
9746 acobsolete.m4, suggested by Alexandre Duret-Lutz.
9748 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

9751 refer to the correct file.
9752 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9753 the behavior of the third argument.
9754 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9755 correctly the behavior of the third argument. Document
9756 what the three macros that AU_DEFUN defines do. Fix
9757 warning message when the third argument includes $0
9758 (reported by Alexandre Duret-Lutz).
9760 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9761 Eric Sunshine <sunshine@sunshineco.com>
9762 Paul Eggert <eggert@twinsun.com>
9764 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9765 (AS_INIT): Output shell initialization there. Removed optional
9766 parameter. Expand _AS_SHELL_FN_SPY.
9767 (AS_INIT_WITH_SHELL_FN): Removed.
9768 (_AS_SHELL_FN_SPY): New macro.
9769 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9770 macros.
9771 (AS_SHELL_SANITIZE): Remove loop to find better shell
9772 and documentation for the parameter.
9773 (_AS_DETECT_BETTER_SHELL): Move it here.
9774 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
9775 (_AS_RUN): Move it here, support testing with eval.
9776 (AS_REQUIRE_SHELL_FN): Require shell functions when
9777 it is used.
9778 (_AS_LINENO_WORKS): Put around braces, we do not
9779 trigger the bash bug anymore.
9780 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9781 use AS_INIT_WITH_SHELL_FN.
9782 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9784 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9786 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
9787 * doc/autoconf.texi: Don't say that the third parameter
9788 is broken.
9789 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
9790 (AU_DEFUN): Honor the third parameter, create autoupdate
9791 macros with AU_DEFINE.
9792 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9793 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
9794 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
9795 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
9796 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

9801 * lib/autoconf/status.m4: Remove FIXME.
9802 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
9803 that the macro is not present anymore in the updated
9804 configure.ac.
9805 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
9806 of autoupdate.
9808 2004-01-28 Paul Eggert <eggert@twinsun.com>
9810 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
9811 copyright years.
9812 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9813 2003 (except 1997) to the list of copyright years. This undoes
9814 the 2003-05-22 change, which removed the older years from the list.
9815 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9817 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9818 Albert Chin-A-Young <china@thewrittenword.com>

9824 AC_PROG_GREP.

9826 egrep and fgrep respectively if $GREP -E/-F don't work.
9827 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9828 _AC_PROG_GREP, and AC_PROG_SED.
9829 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9830 longest input length accepted by a command.
9831 (AC_PROG_SED): Use it.
9832 * doc/autoconf.texi (Particular Programs): Document the changes.
9833 * NEWS: Updated.
9835 2004-01-27 Paul Eggert <eggert@twinsun.com>
9837 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
9838 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9839 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9840 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9842 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9843 bin/autoconf.in, config/Makefile.in, config/config.guess,
9844 config/config.sub, config/install-sh, config/mdate-sh,

9857 sources.
9859 2004-01-26 Paul Eggert <eggert@twinsun.com>
9861 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9862 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9863 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9864 not <inttypes.h>. Problem reported by Tim Mooney in
9865 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9866 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9867 Likewise.
9869 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9870 otherwise "make check" fails because it forbids cmp (I guess
9871 because cmp treats files as binary on DOS-like systems).
9873 * tests/mktests.sh: Update copyright date to 2004, since some tests
9874 have changed in 2004.
9876 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9878 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9879 non-truncating sed or gsed program in PATH.
9880 * tests/acprograms.at: Add it.
9881 * doc/autoconf.texi (Particular Programs): Document it.
9882 * NEWS: Updated.
9884 2004-01-15 Paul Eggert <eggert@twinsun.com>
9886 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9887 -std1 disables some useful extensions on Tru64. Problem reported
9888 by N. Lichtmaier in
9889 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9891 2004-01-14 Paul Eggert <eggert@twinsun.com>
9893 * doc/autoconf.texi (Programming in M4sh): Document that
9894 AS_MKDIR_P succeeds if the destination is a symbolic link
9895 to an existing directory.
9896 (Limitations of Usual Tools): Note that mkdir -p might not
9897 succeed on symlinks to directories.
9899 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9901 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9902 * bin/autoheader.in: Grammar fix in message.
9903 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9904 Test for dir before calling mkdir -p. (trivial changes)
9906 2004-01-13 Eric Blake <ebb9@byu.net>
9908 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9909 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9911 2004-01-10 Jim Meyering <jim@meyering.net>
9913 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9915 2004-01-09 Paul Eggert <eggert@twinsun.com>
9917 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9918 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9919 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9920 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9921 AC_COMPILE_IFELSE, since we now assume our caller invokes
9922 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9923 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9924 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9925 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9927 2004-01-07 Paul Eggert <eggert@twinsun.com>
9929 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9930 `"'...'"`, as it's confusing (and I suspect it may not work on
9931 some platforms). The code was incorrect anyway, as it assumed
9932 that \$ evaluated to itself in that context. Reported by
9933 Alexandre Duret-Lutz.
9935 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9937 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9938 and _LT_AC_TAGCONFIG.
9940 2004-01-06 Paul Eggert <eggert@twinsun.com>
9942 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9943 example, and add more examples. Reported by Eric Sunshine.
9945 2004-01-05 Paul Eggert <eggert@twinsun.com>
9947 * doc/autoconf.texi (Limitations of Usual Tools):
9948 Remove warning against "rm -fr" introduced yesterday; it
9949 was a false alarm.
9951 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9952 autoscan, autoupdate, ifnames): Don't use chmod -w.
9953 * lib/Makefile.am (autom4te.cfg): Likewise.
9954 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9955 "chmod -w".
9957 2004-01-04 Paul Eggert <eggert@twinsun.com>
9958 Paolo Bonzini <bonzini@gnu.org>
9960 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9961 by doing lineno substitution only on lines containing "$LINENO".
9963 2004-01-04 Paul Eggert <eggert@twinsun.com>
9965 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9966 Use "rm -f" to remove conftest.sed, not plain "rm".
9967 Bug reported by David Relson in
9968 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9970 * Makefile.am (autom4te-update):
9971 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9972 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9973 * doc/autoconf.texi (Guidelines): Likewise.
9974 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

9978 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
9979 * tests/Makefile.am (clean-local): Likewise.
9980 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9981 srcdir): Likewise.
9982 * doc/autoconf.texi (Limitations of Usual Tools):
9983 Warn against "rm -fr".
9985 2004-01-03 Paul Eggert <eggert@twinsun.com>
9987 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9988 -c -o might not work. From a suggestion by Kevin Ryde.
9989 (C Compiler, Generating Sources, Limitations
9990 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9991 Don't put '-o' after non-options, as POSIX doesn't allow this.
9992 Mention that cc's name might be gcc or c89 or whatever.
9994 2004-01-04 Kevin Ryde <user42@zip.com.au>
9996 * doc/autoconf.texi: Add various further index entries.
9998 2003-12-29 Paul Eggert <eggert@twinsun.com>
10000 * bin/autoreconf.in (autoreconf_current_directory):
10001 Fix typo: mkdir without umask arg.
10003 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10005 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10006 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10007 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10008 explanation clearer.
10010 2003-12-24 Andreas Schwab <schwab@suse.de>
10012 * doc/autoconf.texi (Default Includes): Fix misspelling of
10013 AC_INCLUDES_DEFAULT.
10015 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10017 * configure.ac: Test if sh -n works.
10018 * configure: Regenerate.
10019 * tests/atlocal.in: Store the result here.
10020 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
10021 tools.at, looking in atlocal's ac_cv_sh_n_works instead
10022 of explicitly testing.
10023 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10024 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10025 * tests/tools.at (Syntax of the shell scripts): Simplify
10026 using AT_CHECK_SHELL_SYNTAX.
10027 (Syntax of the Perl scripts): Remove definition of
10028 AT_CHECK_PERL_SYNTAX.
10030 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10032 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
10033 stderr to /dev/null.
10034 * bin/autoconf.in: Regenerate.
10035 * bin/wrapper.in: Regenerate.
10037 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
10039 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
10040 Extracted from AS_SHELL_SANITIZE.
10041 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
10042 macros.
10043 (AS_SHELL_SANITIZE): Move reinvocation code from
10044 _AS_LINENO_WORKS, use it to find out if shell
10045 functions work.
10046 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
10047 does not work.
10048 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

10060 (&sizes): New.
10061 Use them.
10062 No longer rely on Gnus to inline the list of signatures: compute
10063 them on the fly.
10065 2003-11-24 Akim Demaille <akim@epita.fr>
10067 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
10068 override some files.
10069 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
10070 From Debian Autoconf 2.58.
10072 2003-11-24 Akim Demaille <akim@epita.fr>
10074 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote $ac_popdir

10086 Make wording more consistent.

10095 parameter of AU_DEFUN.
10096 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
10097 (AU_DEFUN): Remove the third parameter, it was not used.
10098 Use AC_DEFUN directly, not AU_DEFINE.

10112 use or not use the system type.
10114 2003-11-12 Derek Price <derek@ximbiot.com>
10116 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10136 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

10195 * Makefile.cfg (local_updates, executable-update): Tweak to be
10196 robust to parallel makes.
10197 Suggested by Alexandre Duret-Lutz.
10199 2003-10-27 Akim Demaille <akim@epita.fr>
10201 * Makefile.cfg (executable-update): New.

10216 2003-10-23 Akim Demaille <akim@epita.fr>
10218 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT): Functions using

10274 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
10276 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
10277 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10279 2003-10-10 Andreas Schwab <schwab@suse.de>
10281 * bin/autoheader.in: Avoid empty first line in --version and
10282 --help output.
10283 * bin/ifnames.in: Likewise.
10285 2003-10-09 Paul Eggert <eggert@twinsun.com>

10293 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10294 -mGLOB_options_string stuff for Intel ifc, which can cause
10295 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10296 pattern-matching instead of grep.
10298 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10300 * doc/autoconf.texi: Document new FC Fortran macros.

10308 * NEWS: Updated.
10310 2003-10-06 Gary V. Vaughan <gary@gnu.org>
10312 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add

10314 -lcrt[01].o.
10316 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10318 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10319 cache variable instead of $G77 to decide whether to include -O2,
10320 since $G77 is specific to Fortran 77.
10322 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10324 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

10327 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10329 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10330 arguments so that it can be used with syntax identical to
10331 AC_PROG_F77, and so that we can more easily decide to
10332 remove/deprecate the DIALECT optional argument in the future if it
10333 proves troublesome.
10334 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10335 non-freeform-supporting compilers. Document freeform flags.
10337 2003-10-03 Akim Demaille <akim@epita.fr>
10339 * configure.ac: Look for emacs, not macs.
10340 Reported by Eric Sunshine.
10342 2003-10-03 Akim Demaille <akim@epita.fr>
10344 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10345 * bin/autoreconf.in (autoreconf_current_directory): Create the
10346 AUX_DIR if needed, for sake of automake --add-missing etc.
10347 Suggested by Alexandre Duret-Lutz.
10349 2003-10-03 Akim Demaille <akim@epita.fr>
10351 * configure.ac: Quotation and formatting changes.

10373 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
10374 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
10376 2003-09-30 Akim Demaille <akim@epita.fr>
10378 * config/announce-gen (&print_news_deltas): Extracted from...
10379 (&print_changelog_deltas): here.
10380 (&news_file): Rename as...
10381 (@news_file): this.
10383 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10385 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10386 have been created when invoking the compiler.
10387 * tests/fortran.at (GNU Fortran 77): Quote $G77.
10389 2003-09-29 Akim Demaille <akim@epita.fr>
10391 Version 2.57e.

10398 Problem reported by Lars J. Aas in
10399 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10400 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10401 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10402 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10404 2003-09-26 Akim Demaille <akim@epita.fr>
10406 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10407 directory for AC_CONFIG_COMMANDS' first argument exists.
10408 This makes valid the invocation of _AC_SRCPATH that follows.
10409 Reported by Eric Sunshine.
10410 * doc/autoconf.texi (Configuration Commands): Adjust.
10412 2003-09-26 Akim Demaille <akim@epita.fr>
10414 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10415 Reported by Ralf Corsepius.
10417 2003-09-26 Akim Demaille <akim@epita.fr>
10419 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10420 arguments.
10421 Actually, use AU_ALIAS.
10422 From Bruno Haible.
10424 2003-09-26 Paul Eggert <eggert@twinsun.com>
10426 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
10427 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
10428 Problem reported by Eric Sunshine in:

10431 2003-09-26 Akim Demaille <akim@epita.fr>
10433 The test suite are sometimes assigning timings incorrectly.
10434 Reported by Henk Krus.
10435 Diagnosed by Nicolas Joly.
10437 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10438 AT_help_all.
10439 Instead of making AT_help a sequence of assignments to grow
10440 $at_help_all, just make AT_help_all be the growing contents of
10441 $at_help_all, and make a single assignment in...
10442 (AT_INIT): here.
10443 (at_times_skip): Flip the meaning and rename as...
10444 (at_times_p): this.
10445 (AT_INIT): When summarizing the test that ran, remove
10446 $at_times_file after use, and check it is present before trying to
10447 use it.
10449 2003-09-25 Akim Demaille <akim@epita.fr>
10451 Version 2.57d.
10453 * bin/Makefile.am (edit): Handle '@configure_input@'.
10454 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10455 (ifnames): chmod -w.
10456 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10457 executables, not bin/ executables! Otherwise all the magic needed
10458 to find non installed files is turned off. This caused a failure
10459 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10460 as found in its environment (sent by tests/autoreconf): pointing
10461 to bin/autom4te that could not find its files.
10462 * tests/mktests.sh: Force the replacement of generated files, for
10463 the sake of "mv" program that are interactive when overwriting a
10464 -w file.
10465 * config/install-sh: Upgrade from CVS Automake.
10467 2003-09-23 Paul Eggert <eggert@twinsun.com>

10470 versus test -L issues.
10472 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10473 Paul Eggert <eggert@twinsun.com>
10475 Trivial change to support GCC's configuration procedure.
10476 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10477 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10478 about inconsistency if the preprocessor is set to give errors for
10479 any warning.
10480 * doc/autoconf.texi (C Compiler Characteristics): Document this.
10482 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

10495 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
10496 from masters.
10498 2003-09-12 Akim Demaille <akim@epita.fr>
10500 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
10501 not asm/types.h.
10503 2003-09-11 Akim Demaille <akim@epita.fr>
10505 * doc/autoconf.texi (Header Portability): linux/random.h.
10506 From Peter Hendrickson.
10508 2003-09-10 Akim Demaille <akim@epita.fr>
10510 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10511 willing to edit the output files.
10513 2003-09-10 Akim Demaille <akim@epita.fr>
10515 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10516 and AC_FC_FREEFORM.
10517 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10518 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10520 2003-09-09 Akim Demaille <akim@epita.fr>

10529 trailing files.
10531 2003-09-07 Paul Eggert <eggert@twinsun.com>
10533 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10534 Improve the accuracy of the wording about obsolescence.
10535 From a suggestion by Ian Lance Taylor in
10536 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10538 2003-09-05 Paul Eggert <eggert@twinsun.com>
10540 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10541 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10543 2003-09-04 Akim Demaille <akim@epita.fr>
10545 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10546 AC_FUNC_WAIT3.
10548 2003-09-04 Akim Demaille <akim@epita.fr>
10550 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10551 (freeze): When exiting, use $exit_code.
10552 * lib/autoconf/fortran.m4: Comment changes.
10554 2003-09-04 Akim Demaille <akim@epita.fr>
10556 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10558 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10560 Add support for newer Fortran dialects. The F77 interface is
10561 unchanged, and continues to support Fortran 77. New FC macros
10562 correspond to all the old F77 macros, with output variables FC,
10563 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10564 available dialect, but older dialects can be specified. There are
10565 new macros AC_FC_SRCEXT to set the source extension, and
10566 AC_FC_FREEFORM to accept free-form source files.
10568 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10569 New macros.
10570 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

10603 * tests/local.at: Require 2.57.
10604 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that

10659 2003-08-22 Akim Demaille <akim@epita.fr>
10661 Output stack traces in warnings.
10663 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10664 Replace the former...
10665 (m4_warn): Pass the call stack to _m4_warn.
10666 * bin/autom4te.in: Adjust to output the call stack.
10667 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10669 2003-08-22 Akim Demaille <akim@epita.fr>
10671 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

10674 2003-08-21 Akim Demaille <akim@epita.fr>
10676 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10677 (&verbose): Remove.

10679 --verbose.
10680 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10681 * bin/autoupdate.in: Adjust.
10682 Use &verb, not &verbose.
10684 2003-08-21 Akim Demaille <akim@epita.fr>
10686 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10687 &parse_WARNINGS.
10688 ($help): Use Autom4te::ChannelDefs::usage.
10689 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10690 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10692 2003-08-21 Akim Demaille <akim@epita.fr>
10694 First stab at preserving warnings between calls to autom4te,
10695 including when the cache is used.
10697 There are still several issues: (i) there are too many runs of m4
10698 (one for include, one for warnings, and some more), (ii) warnings
10699 spreading on several lines are not handled gracefully, (iii) the
10700 code meant to have the call stack display for errors does not work
10701 (its handling should move from m4 to autom4te).
10703 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10704 Use them.
10705 (@preselect): Add m4_warn.
10706 ($exit_status): Remove, use $exit_code.
10707 ($help): Use Autom4te::ChannelDefs::usage.
10708 (&handle_m4): No longer define the m4_warnings.
10709 At each run, extract and report the warnings.
10710 Always cache the result, including if the exit status is on
10711 failure, since if nothing changes, we should result in the same
10712 failure, hence we can use the cache.
10713 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10714 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10715 Remove.
10716 (m4_warn): Redefine as a do-nothing: it is its invocation that
10717 matters, as warnings are now reported via traces.
10718 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10719 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10720 the latter reveals calls to the former.
10722 Adjust the tests.
10724 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10726 2003-08-21 Akim Demaille <akim@epita.fr>
10728 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

10733 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in

10735 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10736 (&parse_warnings): Accept a list of warning requests.
10737 (&usage): Return a string, not a side effect.
10738 (cross): New warning category.
10740 2003-08-21 Akim Demaille <akim@epita.fr>
10742 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10743 (&require_configure_ac): Accept an optional directory argument.
10744 ($configure_ac): Remove.
10745 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10746 (&catfile): Remove.
10747 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10748 * bin/autoscan.in: Adjust.
10750 2003-08-20 Akim Demaille <akim@epita.fr>
10752 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10753 Reported by Alexandre Duret-Lutz.
10755 2003-08-20 Akim Demaille <akim@epita.fr>
10757 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10758 * bin/autom4te: Adjust.
10759 In particular, be Autoconf tools are really silent when properly
10760 working, bind the verbosity of the 'note' channel to $verbose.
10761 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10762 (&xsystem, &contents): Remove, since they are exported by...
10763 * lib/Autom4te/FileUtils.pm: this.
10764 More perldoc.
10765 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10766 * lib/Autom4te/FileUtils.pm: here.
10768 2003-08-20 Akim Demaille <akim@epita.fr>
10770 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10771 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10772 from CVS Automake.

10776 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10777 (autom4te-update): New.
10778 * Makefile.cfg (update): Bind autom4te-update.
10780 2003-08-19 Derek Price <derek@ximbiot.com>
10782 * lib/autotest/general.m4: Comment various HELP_* diversions.

10821 2003-08-14 Derek Price <derek@ximbiot.com>
10823 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10824 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10825 shorter column three. Add DESCRIPTION to log file content.
10827 2003-08-13 Derek Price <derek@ximbiot.com>
10829 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10830 output.
10832 2003-08-12 Derek Price <derek@ximbiot.com>
10834 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10835 (AT_CHECK_NOESCAPE): Move core functionality to...
10836 (_AT_CHECK): ...this new macro.
10838 2003-08-07 Derek Price <derek@ximbiot.com>
10840 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10841 (AT_CHECK_NOESCAPE): ...to this new macro.
10843 2003-07-31 Paul Eggert <eggert@twinsun.com>
10845 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10846 in Bash 2.01. Problem reported by Brian Gough in
10847 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10849 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10851 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10852 -lcrt1.o, for OS X. (trivial change)
10854 2003-07-07 Paul Eggert <eggert@twinsun.com>
10856 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10857 inside '#ifndef __cplusplus'. Problem reported by
10858 Bob Friesenhahn.
10860 2003-07-06 Bill Clarke <llib@computer.org>
10862 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10863 'long', not 'int', for benefit of Sun's recent C++ compilers
10864 (trivial change). See:
10865 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10866 (This really should be 'intptr_t', not 'long', but that would
10867 take more work.)
10869 2003-06-25 Akim Demaille <akim@epita.fr>
10871 * lib/Makefile.am (autom4te.cfg): Make it read only.
10872 Depend on Makefile since it contains substitutions.
10873 From Paolo Bonzini.
10874 * lib/autom4te.in (args): Add local.at? for Autotest args.
10875 This change was made on autom4te.cfg which is generated.
10876 Reported by Raja R. Harinath.
10878 2003-06-25 Akim Demaille <akim@epita.fr>
10880 * doc/autoconf.texi (Header Portability): sys/mount.h.
10881 From Gareth McCaughan.
10883 2003-06-23 Akim Demaille <akim@epita.fr>
10885 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10886 not all of them. This fixes 1. the fact that when testing
10887 Autoconf there are many many config.log, 2. the incorrect use of
10888 top_srcdir to find config.log.
10889 Don't mix the detailed output of failed test with the summary of
10890 failures. Rather, append detailed log afterwards.
10892 2003-06-23 Akim Demaille <akim@epita.fr>
10894 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10895 always run: output config.log on $at_group_log.
10897 2003-06-23 Akim Demaille <akim@epita.fr>
10899 * tests/torture.at (#define header templates): Don't use quotes in
10900 C++ comments as it puzzles Emacs' sh font-lock-mode.
10902 2003-06-23 Akim Demaille <akim@epita.fr>
10904 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10905 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10906 * tests/atspecific.m4: Rename as...
10907 * tests/local.at: This.

10913 2003-06-21 Kevin Ryde <user42@zip.com.au>
10915 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10916 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10917 ensuring we add -std1 for full-ANSI.
10919 * doc/autoconf.texi (hdrindex): New macro.
10920 Add index entries for portability of various standard header files.
10922 2003-06-20 Akim Demaille <akim@epita.fr>
10924 * configure.ac: Bump to 2.57b.
10926 2003-06-20 Akim Demaille <akim@epita.fr>
10928 Version 2.57a.
10930 2003-06-20 Akim Demaille <akim@epita.fr>
10932 * bin/autom4te.in: Don't rely on $HOME being defined.
10933 Reported by Marc Espie as PR/233.
10935 2003-06-20 Akim Demaille <akim@epita.fr>
10937 * lib/autotest/general.m4: Use at_times_file only if used.
10938 From Nicolas Joly.
10940 2003-06-20 Akim Demaille <akim@epita.fr>
10942 * config/config.guess, config/config.sub, config/elisp-comp,

10944 Update from masters.
10946 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10948 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF

10950 (TEST_SCRIPT): New diversion.
10951 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10952 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10953 (AT_INIT): Support for expected failures.
10955 2003-06-02 Akim Demaille <akim@epita.fr>
10957 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10958 changes.
10959 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10960 Autoconf nor Automake.
10961 (&contents): New, from Automake.
10962 PODify.
10964 2003-05-28 Paul Eggert <eggert@twinsun.com>
10966 * NEWS, doc/autoconf.texi (Particular Functions),
10967 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10968 is the inverse of localtime.
10970 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10972 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10973 (handle_exec_errors): New function. Work around $! being
10974 altered by WEXITSTATUS.
10975 (xqx, xsystem): Use handle_exec_errors.
10977 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10979 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10980 Do not call `_exit()', simply modify `$?'.
10981 (xsystem): Reset $! before running system, and check it afterward.
10982 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10983 63 for version mismatches.
10985 2003-05-23 Akim Demaille <akim@epita.fr>
10987 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10988 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10989 the middle of a line).
10990 * lib/m4sugar/m4sugar.m4: Likewise.
10991 Remove useless spaces in comments.
10993 2003-05-23 Akim Demaille <akim@epita.fr>
10995 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10996 exit 63, so that we (or Automake's "missing") can tell the
10997 difference with a plain failure.
10998 * doc/autoconf.texi (Notices): Adjust.
11000 2003-05-23 Akim Demaille <akim@epita.fr>
11002 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11003 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11004 White spaces cleanup.
11006 2003-05-22 Jim Meyering <jim@meyering.net>
11007 Paul Eggert <eggert@twinsun.com>
11009 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11010 Remove `#include <stdlib.h>' from the list; we should never
11011 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11012 resulting namespace pollution would cause other tests to fail.
11013 Configure scripts run with some older versions of g++ and HP's
11014 aCC would fail due to such an #include. Problems reported by
11015 Matthew Mueller in <http://bugs.debian.org/120704> and by
11016 Keith Bostic in
11017 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11018 In the test, use the test declaration before including <stdlib.h>,
11019 as that's closer to how it'll be used.
11021 2003-05-23 Akim Demaille <akim@epita.fr>
11023 * doc/autoconf.texi (Header Portability): ucred.h.
11024 From Ian Redfern.
11026 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11028 Overhaul Autotest's logging: generate separate log files
11029 in testsuite.dir/NNN/testsuite.log, and append them to
11030 testsuite.log instead of re-running the test verbosely.
11032 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11033 file descriptor, write 0 to at_status_file instead of setting
11034 at_status=0, initialize some new variables (at_status_file,
11035 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11036 to rerun the tests, instead append the at_group_log to the
11037 at_suite_log when a test fails.
11038 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11039 with the AS_MESSAGE_LOG_FD redirected to stdout.

11041 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11042 its original place.
11043 (AT_CHECK): since tests are run with a redirected stdout,
11044 and used to be re-run in verbose mode, turn some $at_verbose
11045 into echo, and don't redirect the output of testing stdout
11046 and stderr.
11048 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11049 the name of the debugging directory and information about
11050 its contents.

11169 2003-05-06 Akim Demaille <akim@epita.fr>
11171 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11172 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11173 by aclocal.m4 is changed it might require the importing of another
11174 m4 extension file, i.e., aclocal must be run.
11176 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11177 (&parse_args): Use --force with aclocal if required and supported.

11191 2003-04-29 Derek Price <derek@ximbiot.com>
11193 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11194 seperator with m4_append_uniq(). It doesn't work.
11195 (AT_CLEANUP): Add `;' to end of at_help_all.
11196 (AT_INIT): Allow --keywords to be specified more than once. When
11197 grepping $at_help_all for keywords, use the field and keyword
11198 seperators to ensure a complete keyword match. Alter at_prev handling
11199 to support the new --keywords behavior.
11201 2003-04-27 Karl Berry <karl@freefriends.org>
11203 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11204 align better with others. I also made some of the individual

11251 2003-03-31 Derek Price <derek@ximbiot.com>

11277 * tests/torture.at (Configuring subdirectories): Require aclocal
11278 1.4, otherwise the test fails, as it does support configure.ac.

11404 is not portable inside Makefile.
11406 2003-02-20 Akim Demaille <akim@epita.fr>
11408 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

11426 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11427 innocuous variant befor including <limits.h> or <assert.h>. This
11428 works around a bug reported by Albert Chin: HP-UX 11i
11429 (and earlier versions) have a <limits.h> that declares
11430 gettimeofday and many other functions.
11432 2002-12-03 Paul Eggert <eggert@twinsun.com>

11441 nontrivially in main's body, so that f's external declaration is
11442 not optimized away in AIX. This should fix the bug reported by
11443 Martin Frydl in
11444 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11446 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11447 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11448 defined, to support freestanding compilers. This should fix the
11449 bug reported by Momchil Velkov in
11450 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11452 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11453 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11454 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11455 by Simon Josefsson in
11456 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11458 * Makefile.maint (www-gnu): New macro.

11460 the location has moved.
11462 2002-12-02 Martin Frydl <martin@systinet.com>

11484 Update from masters.
11486 2002-11-14 Akim Demaille <akim@epita.fr>
11488 * Makefile.maint: Sync with Bison, i.e.:
11489 (po-check): Scan .l and .y files instead of the
11490 .c and the .h files that they generate. This fixes the bug
11491 reported by Tim Van Holder in:
11492 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11493 Look for N_ as well as for _. Try to avoid matching #define for
11494 N_ and _.
11495 From Paul Eggert.

11510 than assigning in main, to avoid HP cc +O3 optimizing it away.

11550 2002-11-05 Akim Demaille <akim@epita.fr>
11552 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11553 Remove.
11554 We _have_ to stop using the old compatibility scheme that tried to
11555 avoid useless backslashes because Libtool 1.4.3 contains a
11556 AC_DEFINE([error_t], [int],
11557 [Define to a type to use for \`error_t' if it is not
11558 otherwise available.])
11559 We _have_ to quote the single quote and backslashes with \. The
11560 old compatibility scheme saw that ` was backslashed, and therefore
11561 did not quote the single quote. Hence before this patch, Autoconf
11562 was not compatible with Libtool.

11608 Make variable, not a shell variable.
11609 Suggested by Bruno Haible.
11611 2002-10-31 Akim Demaille <akim@epita.fr>

11973 that error messages can be easily located, and use GNU Make
11974 format, so that Emacs' compile mode understands us.
11975 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11976 if some file was changed instead of `print'.
11977 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11978 (&parse_args): Remove the dead options.
11979 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11980 autoheader's quiet mode.
11981 (AT_CHECK_AUTOUPDATE): Likewise.
11982 * tests/tools.at (autoupdate): Adjust.
11983 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11985 2002-10-11 Akim Demaille <akim@epita.fr>
11987 No longer use CPP to check for the existing of headers: use CC to
11988 check for compilability.
11990 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11991 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
11992 (_AC_CHECK_HEADER_NEW): Rename as...
11993 (AC_CHECK_HEADER): this.
11995 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11996 numbers in the Subject suggestion.
11998 2002-10-11 Akim Demaille <akim@epita.fr>
12000 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
12001 Suggest using AC_CHECK_DECLS instead.
12003 2002-10-11 Akim Demaille <akim@epita.fr>
12005 * tests/torture.at (AC_ARG_VAR): Have configure report the value
12006 of `precious'.
12008 2002-10-11 Akim Demaille <akim@epita.fr>
12010 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12011 file name to enable parallel executions.
12012 From Sam Varshavchik.
12014 2002-10-08 Akim Demaille <akim@epita.fr>
12016 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12017 aclocal invocation, as Gettext macros might not be visible to
12018 aclocal.
12019 Instead of blindly running autopoint, scan configure.ac (not the
12020 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12021 Reported by Paul D. Smith.
12023 2002-10-08 Paul Eggert <eggert@twinsun.com>
12025 Work around problems found when POSIXLY_CORRECT=1 is set.
12026 None of this seems to have anything to do with POSIX, really,
12027 but it's how Perl getopt works.
12028 * bin/autom4te.in (parse_args): Configure GetOpt with
12029 "permute", too.
12030 * doc/autoconf.texi (Invoking autom4te):
12031 --warning -> --warnings.
12032 * lib/autom4te.in: --warning -> --warnings.
12034 2002-09-28 Akim Demaille <akim@epita.fr>
12036 * doc/autoconf.texi (autom4te.cache): New section.
12038 2002-09-28 Akim Demaille <akim@epita.fr>
12040 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
12041 (Automake-preselections): Update.
12042 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
12044 2002-09-28 Akim Demaille <akim@epita.fr>
12046 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
12047 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
12048 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12049 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12051 2002-09-28 Akim Demaille <akim@epita.fr>
12053 * tests/torture.at (Configuring subdirectories): Be robust to
12054 users who use config.site to require for a cache: in this case,
12055 the two last configure runs, using two different sets of
12056 arguments, trigger a legitimate error.
12058 2002-09-28 Akim Demaille <akim@epita.fr>
12060 * tests/m4sh.at (Functions Support, Functions and return Support):
12061 New.
12063 2002-09-28 Akim Demaille <akim@epita.fr>
12065 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12066 autoheader are Perl programs.
12067 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12068 (autom4te): Specify that the sources are in the $srcdir.
12069 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12071 2002-09-28 Akim Demaille <akim@epita.fr>
12073 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
12074 (tm_zone): Move their rules to...
12075 * lib/autoconf/types.m4: here, using AN_ macros.
12076 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12077 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12078 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12079 * lib/autoconf/programs.m4: here.
12080 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
12081 (ETAGS_FOR_AUTOCONF): New.
12082 Use it.
12084 2002-09-28 Akim Demaille <akim@epita.fr>
12086 * lib/autoconf/autoscan.m4: New file.
12087 * lib/autoconf/autoconf.m4: Include it.
12088 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12089 that were listed in the original autoscan.list.
12090 * lib/autoconf/headers.m4: Similarly with headers.
12091 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12092 (.m4.m4f): Don't pass --prepend-include, since that's done by
12093 tests/autom4te itself.
12094 * lib/autoscan/Makefile.am: Include freeze.mk.
12095 (autoscan.list): New target --this file is no longer a source.
12096 (autoscan.pre): New file.
12098 2002-09-28 Akim Demaille <akim@epita.fr>
12100 * bin/autoscan.in (@kinds): Make them singular.
12101 Adjust all uses.
12102 (&init_tables): When --debug, report the list of rules to ease
12103 tracking changes in autoscan.list.
12104 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12106 2002-09-28 Akim Demaille <akim@epita.fr>
12108 * lib/autoscan/functions, lib/autoscan/headers,
12109 * lib/autoscan/identifiers, lib/autoscan/makevars,
12110 * lib/autoscan/programs: Merge into...
12111 * lib/autoscan/autoscan.list: this.
12112 * bin/autoscan.in (&init_tables): Adjust.
12114 2002-09-28 Akim Demaille <akim@epita.fr>
12116 * lib/autoscan/functions, lib/autoscan/headers,
12117 * lib/autoscan/identifiers, lib/autoscan/makevars,
12118 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12119 `functions' line is now prefixed with `function:'.
12120 * bin/autoscan.in (&init_tables): Adjust.
12122 2002-09-28 Akim Demaille <akim@epita.fr>
12124 From now on, autoscan files must always map a macro name to a
12125 word: there is no `default' macro for autoscan.
12127 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12128 all.
12129 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12130 explicit.
12132 2002-09-28 Akim Demaille <akim@epita.fr>
12134 * bin/autoscan.in (%c_keywords): Remove.
12135 (&used): Keep only track of the words we might be interested in.
12136 (&output_kind): It is no longer needed to look for non active
12137 checks.
12139 2002-09-27 Akim Demaille <akim@epita.fr>
12141 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12142 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12143 * lib/autoscan/functions: Adjust.
12144 * doc/autoconf.texi (Particular Functions): Adjust.
12146 2002-09-27 Akim Demaille <akim@epita.fr>
12148 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12149 from /tmp.
12150 Thanks to Bill Moseley and Paul Eggert.
12151 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12152 the tmpdir must be created.
12153 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12154 dir be in the build tree, instead of $TMPDIR.
12156 2002-09-27 Akim Demaille <akim@epita.fr>
12158 * bin/autoscan.in: Improve the comments.
12159 (&parse_args): Drop obsolete undocumented options.
12160 (&output_kind): Output warnings.
12161 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
12162 (getwd): Trigger a warning.
12164 2002-09-26 Akim Demaille <akim@epita.fr>
12166 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12167 Reported by Ralf Corsepius.
12168 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12170 2002-09-26 Akim Demaille <akim@epita.fr>
12172 Single suffix rules and seperated dependencies are not portable.
12174 * doc/autoconf.texi (Installation Directory Variables): Update.
12175 (Limitations of Make): Some about `Single Suffix Rules and
12176 Separated Dependencies'.
12177 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12178 (ifnames, autoscan, autom4te): Un-factor into several rules.
12180 2002-09-25 Paul Eggert <eggert@twinsun.com>
12182 * BUGS (Interoperability bugs): New section. Mention libtool
12183 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12185 2002-09-24 Paul Eggert <eggert@twinsun.com>
12187 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12188 make handles suffix-rules differently from GNU make.
12190 * bin/Makefile.am (SUFFIXES, .in): Remove.
12191 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12192 Move the body of the old .in rule here.
12194 2002-09-16 Akim Demaille <akim@epita.fr>
12196 i960 compilers create `b.out' files by default.
12197 Reported by Ralf Corsepius.
12199 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12200 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12202 2002-09-13 Paul Eggert <eggert@twinsun.com>
12204 * doc/autoconf.texi (Particular Headers): Remove obsolete
12205 reference to `struct timezone' in the description of
12206 AC_HEADER_TIME.
12208 2002-09-13 Akim Demaille <akim@epita.fr>
12210 Version 2.54.
12212 * config/config.sub, config/config.guess: Update.
12213 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12214 * Makefile.am: Adjust.
12216 2002-09-13 Akim Demaille <akim@epita.fr>
12218 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12219 reading config.log when the compiler is rejected.
12220 Suggested by Guido Draheim.
12222 2002-09-13 Akim Demaille <akim@epita.fr>
12224 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12225 (chdir_init) might hang when stat'ing mounted directories.
12226 Reported by Vance Shipley.
12228 2002-09-12 Akim Demaille <akim@epita.fr>
12230 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12231 the lists.
12233 2002-09-12 Akim Demaille <akim@epita.fr>
12235 * doc/autoconf.texi (Defining Symbols): Present two different
12236 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12237 difference between 1 argument calls, and 2-3 argument calls.
12239 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12241 * doc/autoconf.texi: Review grammar and punctuation.
12243 2002-09-11 Paul Eggert <eggert@twinsun.com>
12245 * doc/autoconf.texi: Fix minor formatting, spelling, and
12246 grammatical typos.
12247 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12248 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12249 is obsolescent.
12251 2002-09-11 Akim Demaille <akim@epita.fr>
12253 * doc/autoconf.texi (Questions): Rename as...
12254 (FAQ): this.
12255 (Defining Directories): New.
12257 2002-09-09 Akim Demaille <akim@epita.fr>
12259 * doc/autoconf.texi (Making testsuite Scripts): Update.
12260 Suggested by Nishio Futoshi.
12262 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12264 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12265 plain `@' is wanted.
12267 2002-09-09 Akim Demaille <akim@epita.fr>
12269 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12270 `duplicates', since the algorithm was too naive and could keep
12271 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12272 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12273 Reported by Ralf Corsepius.
12274 * tests/torture.at (Configuring subdirectories): Exercise these
12275 cases.
12277 2002-09-09 Akim Demaille <akim@epita.fr>
12279 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12280 looking for a replacement file.
12281 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12282 directory is relative.
12283 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12284 directory definition.
12285 Reported by Andreas Schwab and Jim Meyering.
12287 2002-09-06 Akim Demaille <akim@epita.fr>
12289 * doc/autoconf.texi (Setting Output Variables): Clarify what
12290 precious variables are.
12291 Suggested by Pontus Skoeld.
12293 2002-09-05 Akim Demaille <akim@epita.fr>
12295 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12296 (ifnames, autoscan, autom4te): Since we don't only depend on
12297 configure.ac variables (such as VERSION etc.), but also on prefix
12298 and so forth, depend on Makefile, not configure.ac.
12299 Reported by Alexandre Duret-Lutz.
12300 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12302 2002-09-05 Kevin Ryde <user42@zip.com.au>
12304 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12305 doesn't seem to be confined to ia64, just say "some versions".
12307 2002-09-04 Akim Demaille <akim@epita.fr>
12309 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12310 Automake 1.6c.
12311 * Makefile.am (maintainer-clean-local): Remove.
12312 (MAINTAINERCLEANFILES): Remove COPYING.
12314 2002-09-03 Paul Eggert <eggert@twinsun.com>
12316 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12317 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12318 Brinkmann.
12320 2002-09-03 Akim Demaille <akim@epita.fr>
12322 * configure.ac: Bump to 2.53d.
12323 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12324 as of today, on Automake's team suggestion.
12326 2002-09-03 Akim Demaille <akim@epita.fr>
12328 Version 2.53c.
12330 2002-09-02 Akim Demaille <akim@epita.fr>
12332 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12333 SITE_MACRO_DIR.
12334 * configure.ac: Disable SITE_MACRO_DIR.
12336 2002-09-02 Jim Meyering <meyering@lucent.com>
12338 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12339 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12340 Also, tweak grammar: s/make sure to/be sure to/.
12342 2002-09-02 Paul Eggert <eggert@twinsun.com>
12344 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12345 directory names are generally preferable to physical names.
12347 2002-09-02 Akim Demaille <akim@epita.fr>
12349 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12350 Reported by Raja R. Harinath.
12351 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12352 * bin/autoupdate.in: Use error instead of die.
12354 2002-09-01 Paul Eggert <eggert@twinsun.com>
12356 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12357 ordinary shell concatenation rather than echo+tr+sed command that
12358 runs afoul of a long-line-related sed bug in Solaris 8.
12360 * bin/autoheader.in (parse_args): --warning -> --warnings.
12362 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12363 stdout, as traditional "ls" does.
12364 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12365 _AC_COMPILER_EXEEXT_O): Likewise.
12366 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12368 * bin/autoconf.as: Add --prepend-include option. This patch was
12369 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12370 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12372 * bin/autoconf.in, configure: Regenerate.
12374 * doc/autoconf.texi (Special Shell Variables): Mention
12375 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12377 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12378 MAILPATH and set PS1, PS2, PS4 to default values, to work
12379 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12380 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12381 the Autoconf documentation specifies; fall back to "unset" only if
12382 this fails. Use a shell for-loop for this rather than an m4 loop,
12383 to shorten the output script.
12385 2002-08-30 Paul Eggert <eggert@twinsun.com>
12387 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12388 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12389 for the CDPATH problem. Document PWD.
12390 (Limitations of Builtins): Document the problem that "cd $foo" and
12391 "ls $foo" may refer to different directories in shells conforming
12392 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12393 example, since the old example is now out of date.
12395 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12396 FOO" and "ls FOO" talk about different directories; this catches
12397 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12398 spaghetti.
12400 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12401 of rolling our own unset.
12402 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12403 in practice we needn't worry about CDPATH if unset doesn't work.
12405 * Makefile.in, aclocal.m4, bin/Makefile.in,
12406 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12407 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12408 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12409 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12410 tests/Makefile.in: Regenerate with Automake 1.6.3.
12412 * config/config.guess, config/config.sub, config/mkinstalldirs:
12413 Update.
12415 * configure: Regenerate with self.
12417 2002-08-30 Kevin Ryde <user42@zip.com.au>
12419 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12420 default output.
12422 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12424 * bin/autom4te.in (Request::load): Correctly test for "do" read
12425 failure.
12427 2002-08-29 Akim Demaille <akim@epita.fr>
12429 * lib/Autom4te/General.pm (&xqx): New.
12430 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12431 hand, which is not portable.
12432 (&error): New.
12433 * bin/autom4te.in: Use them.
12434 Use &error instead of die.
12435 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12436 Adjust.
12438 2002-08-17 Paul Eggert <eggert@twinsun.com>
12440 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12441 default list of compilers to try, since it was long ago superseded
12442 by the ksh fc builtin. Suggested by Steven G. Johnson.
12444 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12446 * doc/autoconf.texi (Invoking autom4te): End the option table,
12447 fixing a bug introduced by the previous patch.
12448 (Limitations of Make): Add a 'target lookup' subentry in the
12449 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12451 2002-07-29 Mark D. Roth <roth@feep.net>
12453 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12454 options and use $AUTOM4TE_PATH.

12465 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12466 Replace with:
12467 (AM_MAKEINFOFLAGS): New macro.
12468 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12469 * Makefile.am (INSTALL): Use the new macros.
12470 Use -o rather than --output, since "missing" does not grok --output.
12472 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12474 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12475 comments do not always work. Never trust the exit status of
12476 `make -k'.
12478 2002-07-24 Kevin Ryde <user42@zip.com.au>
12480 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12481 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

12485 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12486 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12487 apparently treats PATH="nonexistent" as if it contained ".".
12488 Bug reported by Stefan `Sec' Zehl.
12490 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12492 * doc/autoconf.texi (Limitations of Make): Mention the special

12607 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
12609 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12610 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

12612 so that Emacs setups GNU style for perl-mode and cperl-mode.
12614 2002-06-27 Paul Eggert <eggert@twinsun.com>
12616 * config/install-sh: Quote $src. Prefer || to test's -o option,
12617 as per "Limitations of Builtins".
12618 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12619 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12621 * tests/mktests.sh: Use grep instead of fgrep, as per
12622 "Limitations of Builtins".
12624 2002-06-15 Paul Eggert <eggert@twinsun.com>
12626 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12627 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12628 so that we consistently test the just-built programs.
12629 * tests/wrappl.as: Likewise.
12631 2002-06-12 Paul Eggert <eggert@twinsun.com>
12633 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

12637 * bin/autoreconf.in (autoconf, autoheader): Likewise.
12638 * bin/autoscan.in (autom4te): Likewise.
12639 * bin/autoupdate.in (autom4te): Likewise.
12641 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
12642 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
12643 on Solaris 2.5.1.
12645 2002-06-11 Andreas Schwab <schwab@suse.de>
12647 * doc/autoconf.texi: Add more dir entries.
12649 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12651 * bin/autom4te.in ($cache): Don't define using `$me', the name
12652 of the cache should not depend on the name under which autom4te
12653 was installed.
12655 2002-06-07 Akim Demaille <akim@epita.fr>
12657 * tests/tools.at (autoconf: forbidden tokens, basic)

12669 rename as...
12670 (AC_REPLACE_FNMATCH): this.
12671 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12672 AC_FUNC_FNMATCH_GNU.
12674 2002-06-07 Akim Demaille <akim@epita.fr>
12676 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the

12679 2002-06-07 Akim Demaille <akim@epita.fr>
12681 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12682 suggest m4_pattern_allow.
12683 Suggested by Adam J. Richter.
12685 2002-06-07 Akim Demaille <akim@epita.fr>
12687 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12688 ac_config_libobj_dir.
12689 (AC_CONFIG_LIBOBJ_DIR): New.
12690 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12691 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12692 Use ac_config_libobj_dir to find the replacement files.
12693 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12694 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

12696 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
12697 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
12698 * tests/mktests.sh (ac_exclude_list): Don't check

12701 2002-06-06 Paul Eggert <eggert@twinsun.com>
12703 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12704 if ln doesn't work.
12705 * NEWS: Likewise.
12706 * doc/autoconf.texi (Configuration Links): Likewise.

12709 2002-06-05 Paul Eggert <eggert@twinsun.com>
12711 * config/config.guess, config/config.sub, config/texinfo.tex:
12712 Update from masters.
12714 2002-05-29 Paul Eggert <eggert@twinsun.com>
12716 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
12717 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.

12737 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12738 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
12739 instead of AC_MBSTATE_T, which never existed.
12741 2002-05-23 Akim Demaille <akim@epita.fr>
12743 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12744 version of Autoconf that is discussed.
12746 2002-05-22 Paul Eggert <eggert@twinsun.com>
12748 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12749 from the default list of compilers to try. Suggested by
12750 Kate Hedstrom.
12751 * NEWS: Document the above.
12752 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12754 2002-05-17 Paul Eggert <eggert@twinsun.com>
12756 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12757 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12758 This improves on an earlier suggestion by H. Peter Anvin.
12760 2002-05-16 Paul Eggert <eggert@twinsun.com>
12762 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12763 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12764 Both macros now accept an optional source-dir arg.
12765 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12767 * NEWS: Document this.
12768 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12770 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12771 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12772 not for GNU extensions; this undoes part of the 2000-11-03 change,
12773 reverting to 2.13-compatible behavior.
12774 Add new optional argument DIR.
12775 (AC_FUNC_FNMATCH_GNU): New macro.
12777 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12779 2002-05-08 Paul Eggert <eggert@twinsun.com>
12781 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12782 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12783 and it causes a 'test' syntax error if it fails.
12784 Bug reported by Stephen Gildea.
12786 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12787 If prototypes are supported, use them to check this at compile-time,
12788 instead of trying to check it at run-time. If we must do a run-time
12789 check, assume that setvbuf is standard when cross-compiling, as
12790 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12791 Bug reported by Paul D. Smith.
12793 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12794 argument specifying location of getloadavg.c. This removes a
12795 FIXME. This idea was taken from Jim Meyering's implementation in
12796 textutils.
12797 * doc/autoconf.texi (Particular Functions): Document this.
12798 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12799 that's what the code does; this fixes a bug reported by
12800 Paul D. Smith.
12802 2002-05-03 Akim Demaille <akim@epita.fr>
12804 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12805 autopoint instead of gettextize.
12806 ($uses_alocal): Rename as...
12807 ($uses_aclocal): this.
12808 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12809 Suggested by Bruno Haible.
12811 2002-05-03 Akim Demaille <akim@epita.fr>
12813 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12815 2002-04-29 Paul Eggert <eggert@twinsun.com>
12817 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12818 files to be 1 second older; just set them to be the same time.
12819 Also, sleep 1 second after the first aclocal, to work around
12820 problems with sub-second time stamps on the input files.
12822 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12824 * doc/autoconf.texi: Mention "set -e -x" lossage
12825 under node "Limitations of Builtins".
12827 2002-04-29 Akim Demaille <akim@epita.fr>
12829 * doc/install.texi: Better wording for setting variables when
12830 running configure.
12831 From Christian Cornelssen.
12833 2002-04-29 Akim Demaille <akim@epita.fr>
12835 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12836 of lack of $LINENO support, then the test will compare the $LINENO
12837 in testsuite vs. the lineno in the test file. This is wrong, of
12838 course.
12839 Be sure to protect it.
12840 Reported by Patrick Welche.
12842 2002-04-25 Akim Demaille <akim@epita.fr>
12844 * doc/autoconf.texi (Obsolete Macros): Typo.
12845 Reported by Vladimir Volovich.
12847 2002-04-25 Akim Demaille <akim@epita.fr>
12849 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12850 than some of the input files, hence, on the second run of aclocal,
12851 if some of its input are younger, make them older.
12852 Suggested by Paul Eggert.
12854 2002-04-25 Akim Demaille <akim@epita.fr>
12856 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12857 Thanks to Paul Eggert.
12859 2002-04-25 Akim Demaille <akim@epita.fr>
12861 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12862 and ac_subst_vars be sh variables containing the list of
12863 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12864 DEFAULT diversion.
12865 (_AC_INIT_PREPARE): Use them to log them.
12866 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12867 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12868 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12869 _AC_SUBST_FILES and _AC_SUBST_VARS.
12870 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12872 2002-04-24 Akim Demaille <akim@epita.fr>
12874 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12875 autoheader, so that automake does not complain about a missing
12876 config.h.in that was to be created.
12878 2002-04-23 Akim Demaille <akim@epita.fr>
12880 * bin/autoheader.in (parse_args): --warning takes an argument.
12881 Fixes PR/220.
12883 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12885 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

12899 comma.
12900 Reported by Gregory Giannoni.
12902 2002-04-22 Akim Demaille <akim@epita.fr>
12904 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
12905 Fixes false failures on Darwin.
12907 2002-04-21 Paul Eggert <eggert@twinsun.com>

12914 2002-04-20 Paul Eggert <eggert@twinsun.com>
12916 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
12917 ZSH_VERSION fixes. Bug reported by Raja R Harinath.

12930 Minor spelling and grammar fixes.
12932 * doc/autoconf.texi: Follow the outline suggested in the GNU
12933 Sample Texts sections of the Texinfo 4.2 manual. Most
12934 importantly, this makes sure that the copyright notices appear in
12935 all output formats. You probably need Texinfo 4.2 to generate
12936 the manual now.
12938 Fix some bugs when using "$@" when there might be zero positional
12939 arguments in cases where this matters.
12941 * bin/autoconf.as: Rewrite so that the problem does not come up.

12956 Use Zsh alias to work around problem.
12957 * tests/atgeneral.m4 (AT_INIT): Likewise.
12959 * tests/c.at: We can't have zero arguments, so remove workaround
12960 that is not portable to Zsh.
12962 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12964 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

12971 2002-04-10 Akim Demaille <akim@epita.fr>
12973 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12974 workaround for ${1+"$@"}.
12975 * doc/autoconf.texi (Shell Substitutions): Explain it.
12976 From Oliver Kiddle and Peter Stephenson.
12978 Have M4sh perform minimal shell sanitizing.
12980 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12981 part into...
12982 (_AS_PREPARE): this new macro.
12983 (AS_PREPARE): New.
12984 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12985 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12987 Adjust Autoconf and Autotest.
12989 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12990 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12991 * lib/autotest/general.m4 (AT_INIT): Likewise.
12992 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12993 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12994 AS_SHELL_SANITIZE.
12996 Use this M4sh to generate Autoconf's shell scripts.
12998 * tests/wrapsh.as: New, precursor of wrapsh.in.
12999 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13000 on Autotest and M4sh.
13001 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13002 (wrapsh.in): New target.
13003 * bin/autoconf.as: New, precursor of autoconf.in.
13004 (autoconf.in): New target.
13006 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
13008 * doc/autoconf.texi (Limitations of Make): Mention the issue
13009 with indented comments in rules.
13011 2002-04-09 Andreas Schwab <schwab@suse.de>
13013 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
13014 ac_top_builddir when setting ac_abs_top_builddir.
13016 2002-04-06 Kevin Ryde <user42@zip.com.au>
13018 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
13019 (Portable Shell): Cross reference to Systemology.
13021 2002-04-05 Akim Demaille <akim@epita.fr>
13023 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
13024 directories when descending in a SUBDIRS.
13025 Reported by Ezra Peisach.
13027 2002-04-04 Andreas Schwab <schwab@suse.de>
13029 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13030 contains no literal separators.
13032 2002-04-03 Akim Demaille <akim@epita.fr>
13034 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13035 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13036 Use dnl, not the KILL diversion.
13037 Extracted from...
13038 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13039 (AC_CONFIG_LINKS): here.
13040 Adjust.
13041 Don't use the KILL diversion, as it kills spurious output, which
13042 results in failures being hidden.
13043 Use m4_defn where appropriate.
13044 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13045 after the second argument.
13046 Use m4_defn.
13047 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13048 syntax, as it is provided by M4sugar.
13049 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13051 2002-04-03 Andreas Schwab <schwab@suse.de>
13053 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
13054 expanded if $# <= 2.
13056 * bin/autoreconf.in (autoreconf): Run automake after rerunning
13057 aclocal.
13059 2002-04-03 Akim Demaille <akim@epita.fr>

13062 (_AC_COMPILER_EXEEXT_REJECT): New.
13063 Also recognize *.bb and *.bbg as compilation byproducts.
13064 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
13065 (_AC_COMPILER_OBJEXT): Use them.
13066 Fixes Debian #138666.
13068 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13070 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13072 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13073 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13074 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13075 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13076 (AC_C_CONST): Same.
13077 (AC_C_INLINE): Same.
13078 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
13079 * doc/autoconf.texi, NEWS: Document.
13080 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
13081 AC_C_CROSS.

13086 _AS_MKDIR_P_PREPARE.
13088 2002-03-28 Kevin Ryde <user42@zip.com.au>
13090 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13091 to avoid versions of HP C which don't allow that.
13093 2002-03-27 Paul Eggert <eggert@twinsun.com>
13095 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13096 (AS_SHELL_SANITIZE): Invoke it.
13097 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13099 2002-03-26 Akim Demaille <akim@epita.fr>
13101 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13103 2002-03-26 Akim Demaille <akim@epita.fr>
13105 * doc/autoconf.texi (Introduction): The GNATS base moved.
13107 2002-03-25 Paul Eggert <eggert@twinsun.com>
13109 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13110 as POSIX requires, as it doesn't work with Zsh.
13111 * doc/autoconf.texi (Assignments): Document the problem.
13113 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13115 * doc/autoconf.texi (Limitations of Make): Mention more issue
13116 about VPATH, overriding of macros in sub-makes, and handling of
13117 SHELL.
13119 2002-03-21 Paul Eggert <eggert@twinsun.com>
13121 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13122 problem with here-document buffer boundaries.
13124 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13125 when reinvoking the shell, to work around problems with installers
13126 who put strange things like "cd" commands in their environments.
13128 2002-03-19 Akim Demaille <akim@epita.fr>
13130 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13131 From Aaron Ucko.
13133 2002-03-19 Akim Demaille <akim@epita.fr>
13135 * bin/autoscan.in (scan_file): Specify the location in `&used'
13136 invocations.
13137 From Nicolas Joly.
13139 2002-03-19 Akim Demaille <akim@epita.fr>
13141 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13142 From Nishio Futoshi.
13144 2002-03-19 Akim Demaille <akim@epita.fr>
13146 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13148 2002-03-18 Paul Eggert <eggert@twinsun.com>
13150 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13151 (Limitations of Usual Tools): Add mkdir section.
13153 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13154 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13155 back on AS_DIRNAME to compute prefixes otherwise; this is
13156 roughly what mkinstalldirs does. That way, we need not have
13157 our own filename disassembler. The old disassembler did not
13158 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13160 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13161 Create at_test_all by a series of assignments,
13162 not by a single assignment of a long string. The latter causes ksh
13163 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13164 presumably because of a buffer overrun.
13166 2002-03-14 Paul Eggert <eggert@twinsun.com>
13168 * lib/autotest/general.m4 (at_times_skip):
13169 Renamed from at_times. Now a boolean.
13170 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13171 says 'times: not found'.
13173 2002-03-14 Akim Demaille <akim@epita.fr>
13175 * bin/autoreconf.in (&study_gettextize): New.
13176 (&autoreconf): Handle newest gettextize.
13177 Rerun aclocal if needed.
13178 Suggested by Andreas Schwab.
13180 2002-03-13 Akim Demaille <akim@epita.fr>
13182 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13184 2002-03-13 Akim Demaille <akim@epita.fr>
13186 * doc/autoconf.texi (Header Portability): New.
13187 Add information about stdint.h and inttypes.h from Paul Eggert.
13189 2002-03-13 Akim Demaille <akim@epita.fr>
13191 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13192 -p'.
13193 From Bob Proulx.
13195 2002-03-12 Akim Demaille <akim@epita.fr>
13197 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13198 m4_require.
13200 2002-03-11 Andreas Schwab <schwab@suse.de>
13202 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13203 does not do it if --with-lispdir is given.
13205 2002-03-08 Akim Demaille <akim@epita.fr>
13207 Version 2.53.
13209 2002-03-08 Akim Demaille <akim@epita.fr>
13211 * doc/autoconf.texi (Subdirectories): Clarify that the
13212 subdirectory should exist.
13214 2002-03-08 Akim Demaille <akim@epita.fr>
13216 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13218 2002-03-08 Akim Demaille <akim@epita.fr>
13220 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13221 aliases the actual variables, and modifications of the former
13222 affect the latter.
13224 2002-03-08 Akim Demaille <akim@epita.fr>
13226 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13227 because of C-c: have m4 output in tmp files, then mv them.
13229 2002-03-08 Akim Demaille <akim@epita.fr>
13231 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13232 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13233 * bin/ifnames.in: Copyright update.
13235 2002-03-08 Akim Demaille <akim@epita.fr>
13237 * doc/autoconf.texi (Invoking autom4te): New.
13239 2002-03-05 Akim Demaille <akim@epita.fr>
13241 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13242 Kevin Ryde.
13244 2002-03-05 Akim Demaille <akim@epita.fr>
13246 Version 2.52i.
13248 2002-03-04 Akim Demaille <akim@epita.fr>
13250 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13251 * lib/autoconf/general.m4 (AC_INIT): More informative error
13252 message for LIBOBJ.
13254 2002-03-04 Akim Demaille <akim@epita.fr>
13256 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13257 parallel builds.
13259 2002-03-04 Akim Demaille <akim@epita.fr>
13261 * doc/autoconf.texi (Transforming Names): Equality between target
13262 and host is irrelevant.
13263 (Specifying Names, Canonicalizing): Remove all references to the
13264 backward compatibility hooks. Rather, collect them all into...
13265 (Hosts and Cross-Compilation): this new section.
13266 * doc/install.texi (System Type): Ditto.
13267 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13268 that `--host' implies cross-compilation.
13270 2002-03-04 Akim Demaille <akim@epita.fr>
13272 * doc/autoconf.texi (Evaluation Macros): New.
13273 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13274 useless.
13275 (_m4_foreach): Define the variant with immediate evaluation so
13276 that it contains exactly the items, not an expression which
13277 evaluation is the current item.
13278 (m4_re_string, m4_re_word): Don't over quote them.
13280 2002-03-04 Akim Demaille <akim@epita.fr>
13282 Instead of having stacking `shift's evaluated at the end, let
13283 `foreach' loops immediately evaluate them.
13285 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13286 $*. This is the n-th time I change my mind, but hopefully this is
13287 the last...
13288 (m4_lquote): New.
13289 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13290 efficient.
13291 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13292 it was only a hack for m4_text_wrap.
13293 (m4_car2): Remove, replaced by...
13294 (m4_cdr): New.
13295 (_m4_foreach): Adjust.
13296 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13297 m4_bpatsubst for clarification.
13299 2002-03-04 Akim Demaille <akim@epita.fr>
13301 * doc/autoconf.texi (Changequote is Evil): New.

13314 of messages.
13316 2002-02-28 Akim Demaille <akim@epita.fr>

13337 Version 2.52h.
13339 2002-02-07 Akim Demaille <akim@epita.fr>
13341 Fix Autoconf PR/209.
13342 Also reported by Frank Denis.
13344 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13346 2002-02-07 Akim Demaille <akim@epita.fr>
13348 Fix Autoconf PR/207:
13349 AC_PREFIX_PROGRAM fails with dashed program names
13351 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13352 variable when looking for the prefix program.
13353 Now it also works for shell variables.
13355 2002-02-07 Akim Demaille <akim@epita.fr>

13363 case/esac, some shells don't support it.
13364 Reported by Zack Weinberg.
13365 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
13367 2002-02-06 Akim Demaille <akim@epita.fr>

13381 Describe HP-UX cc bug workaround more accurately.
13382 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13383 not unsigned long.
13384 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13385 cross-compilers, too. This undoes some of the most recent change
13386 to this file.
13388 2002-02-05 Akim Demaille <akim@epita.fr>
13390 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13391 to make sure they are up to date when `check' is run.
13393 2002-02-05 Akim Demaille <akim@epita.fr>
13395 * doc/autoconf.texi (Making testsuite Scripts): Document
13396 package.m4.
13398 2002-02-05 Akim Demaille <akim@epita.fr>
13400 * lib/freeze.mk: New.
13402 2002-02-05 Akim Demaille <akim@epita.fr>
13404 Implement `autom4te --freeze'.
13406 * bin/autom4te.in (&freeze): New.
13407 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13408 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13410 2002-02-05 Akim Demaille <akim@epita.fr>
13412 * bin/autom4te.in (&parse_args): Implement `frozen files are
13413 optional are the sum of the previous files on the command line'.
13414 Also, pass `--reload-state=' on them, so...
13415 (handle_m4): don't.
13416 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13417 (M4sh): Rely on M4sugar.
13418 (Autotest, M4sh, M4sugar): Use frozen files.
13420 2002-01-31 Akim Demaille <akim@epita.fr>
13422 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13423 * doc/autoconf.texi (Initializing configure): Adjust.
13425 2002-01-30 Akim Demaille <akim@epita.fr>
13427 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13428 alphanumeric to `-' instead of `_'.
13430 2002-01-30 Akim Demaille <akim@epita.fr>
13432 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13433 for plain code, the other for cross-compilation code. The latter
13434 is now run with GCC only.
13435 * doc/autoconf.texi (Compilers and Preprocessors): New.
13437 2002-01-30 Akim Demaille <akim@epita.fr>
13439 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13440 values.
13441 * doc/autoconf.texi (Initializing configure): Explain how to
13442 change AC_INIT default values.
13444 2002-01-29 Akim Demaille <akim@epita.fr>
13446 * tests/torture.at (Configuring subdirectories): Use configure.in,
13447 so that aclocal 1.4 works.
13448 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13450 2002-01-28 Akim Demaille <akim@epita.fr>
13452 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13453 needs an argument.
13455 2002-01-28 Akim Demaille <akim@epita.fr>
13457 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13458 AUTOTEST_PATH *after* it was set.
13459 Don't put `.' in the PATH: the user should be precise and `./' if
13460 needed. In addition, given that the test suite does some `cd', if
13461 `.' is in the path, the `tested programs' sections will report
13462 programs found in the test suite's directory, while during the
13463 tests (performed in their own directory), these programs are no
13464 longer visible. In other words, the results is confusing and
13465 useless.
13466 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13468 2002-01-24 Akim Demaille <akim@epita.fr>
13470 Version 2.52g.
13472 2002-01-24 Akim Demaille <akim@epita.fr>
13474 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
13475 * doc/autoconf.texi: Finally add Akim as an author.
13477 2002-01-24 Akim Demaille <akim@epita.fr>
13479 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13480 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13481 Bourne. Use /bin/sh.
13482 From Andreas Buening.
13484 2002-01-24 Akim Demaille <akim@epita.fr>
13486 * config/config.guess, config/config.sub, config/texinfo.tex:
13487 Update from masters.
13489 2002-01-24 Akim Demaille <akim@epita.fr>
13491 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
13492 * config/auxdir.m4, config/cond.m4, config/depend.m4,
13493 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
13494 * config/missing.m4, config/sanity.m4, config/select.m4,
13495 * config/strip.m4: Remove, to ease sync'ing with any version of
13496 Automake.
13498 2002-01-24 Akim Demaille <akim@epita.fr>
13500 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13501 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13502 Reported by Geir Ove Myhr.
13504 2002-01-21 Akim Demaille <akim@epita.fr>
13506 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13508 2002-01-21 Akim Demaille <akim@epita.fr>
13510 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13511 message on invalid options.
13512 * bin/autom4te.in (parse_args): Don't use
13513 Autoconf::General::getopt with non valid options.
13515 2002-01-17 Jim Meyering <meyering@lucent.com>
13517 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13518 $ac_cv_exeext so we don't use an old, invalid, cached value.
13520 2002-01-11 Akim Demaille <akim@epita.fr>
13522 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13523 Meyering.
13524 * doc/autoconf.texi (Function Portability): Document the strnlen
13525 limitation.

13529 2002-01-06 Akim Demaille <akim@epita.fr>
13531 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13532 package.m4, since is really depends upon configure.ac, not
13533 configure.
13534 * doc/autoconf.texi (testsuite Scripts): Adjust.
13535 * tests/Makefile.am (package.m4): New.
13536 EXTRA_DIST it since its a source.
13538 2002-01-06 Akim Demaille <akim@epita.fr>
13540 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13541 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13542 and PACKAGE_BUGREPORT from here...
13543 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13544 arguments.
13545 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13546 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13547 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13548 * tests/tools.at (autoheader): Adjust.
13549 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13551 2002-01-06 Akim Demaille <akim@epita.fr>

13555 2002-01-03 Akim Demaille <akim@epita.fr>
13557 * doc/autoconf.texi (Output): Improved wording regarding use of
13558 AC_OUTPUT.
13559 From Olly Betts.
13561 2001-12-18 Kevin Ryde <user42@zip.com.au>
13563 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13564 sometimes needing writable input.
13566 2001-12-17 Jim Meyering <meyering@lucent.com>
13568 * doc/autoconf.texi (New Macros): Tweak wording.
13570 2001-12-14 Akim Demaille <akim@epita.fr>
13572 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13573 trailing files, don't apply `-rf' to files which might not be
13574 created by configure (core, core.*, and *.core), but just `rm -f'.
13575 Suggested by Jonathan Kamens.
13577 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13579 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13581 2001-12-14 Akim Demaille <akim@epita.fr>
13583 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13585 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13587 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13588 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13589 abs_srcdir, top_srcpath to abs_top_srcdir.
13590 (_AC_OUTPUT_FILES): Adjust.
13591 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13592 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13593 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13595 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13597 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13598 C/Fortran linking on HP/UX, by extracting the Fortran library
13599 search path from the LPATH line in the $F77 -v output.
13601 2001-12-12 Kevin Ryde <user42@zip.com.au>
13603 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13604 forbidden file descriptors table.
13606 2001-11-26 Akim Demaille <akim@epita.fr>
13608 * bin/autoscan.in (%c_keywords): Build it at top level.
13609 Map to 1 in order to simplify its uses.
13611 2001-11-26 Akim Demaille <akim@epita.fr>
13613 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13614 Remove $filepath, useless.
13615 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13616 variables, they are really part of the tokens.
13617 Split the input line on spaces and then look for tokens.
13618 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13619 because of `lex$U.$(OBJEXT)'.
13620 (&scan_files): Use "@list" instead of join.
13621 * doc/Makefile.am (CLEANFILES): Add *.fns.
13623 2001-11-26 Akim Demaille <akim@epita.fr>
13625 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13626 Remove, replaced by...
13627 * tests/wrappl.in: Be common for all the Perl executables.
13628 In particular autoscan and autoheader want -I.
13629 * configure.ac: Adjust.
13630 * lib/autoscan/headers: errno.h is portable.
13632 2001-11-26 Akim Demaille <akim@epita.fr>
13634 * bin/autoscan.in (used): New.
13635 Use it.
13637 2001-11-26 Akim Demaille <akim@epita.fr>
13639 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13640 directives.
13641 (&scan_sh_file): Remove a duplicate pattern.
13642 (&check_configure_ac): Use long options.
13643 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13645 2001-11-26 Akim Demaille <akim@epita.fr>
13647 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13648 Before, having a line containing the opening of a multi line
13649 comment made the whole line be ignored.
13651 2001-11-26 Akim Demaille <akim@epita.fr>
13653 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13654 (testsuite Scripts): Be one of its subsection.
13655 (Autotest Logs): New.
13657 2001-11-26 Akim Demaille <akim@epita.fr>
13659 Test groups are now run two directories deeper.
13661 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13662 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13663 at_top_builddir.
13664 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13665 top_srcdir, builddir and top_builddir.
13666 Use `at_*dir' relatively to the directory containing the
13667 suite, use `*dir' when relatively to the current group dir.
13669 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13671 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13672 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13673 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13674 spelling errors.
13676 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13678 * doc/autoconf.texi (Using System Type): Add an example of `case
13679 $host' usage so people quit using `case $target' everywhere.
13681 2001-11-22 Akim Demaille <akim@epita.fr>
13683 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13684 spotted by Jim Meyering.
13686 2001-11-16 Paul Eggert <eggert@twinsun.com>
13688 This patch implements a `long double' suggestion by Oliver Kiddle.
13690 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13691 static, to catch errors if the value isn't known at compile-time
13692 and the compiler supports dynamic arrays. Change its name from
13693 `_array_' to `test_array' to avoid potential name clashes.
13694 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13695 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13696 better than double. Catch a bug in GCC 2.95.2 x86.
13697 * doc/autoconf.texi (C Compiler): Document the above.
13698 * NEWS: Likewise.
13700 2001-11-13 Akim Demaille <akim@epita.fr>
13702 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13703 hand.
13704 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13706 2001-11-13 Akim Demaille <akim@epita.fr>
13708 * lib/autotest/general.m4 (AT_INIT): After having run the test
13709 group, go back to the initial directory, not to at_suite_dir.
13711 2001-11-13 Akim Demaille <akim@epita.fr>
13713 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13714 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13715 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13716 option.
13717 (AT_CHECK_CONFIGURE): Use absolute paths.
13718 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13719 The problem is still the old one: there is no means in M4 (that I
13720 know about) to create a defining macro, because there is no means
13721 to create `$1' etc., therefore, the defining macro ``swallows''
13722 all the arguments meant to the defined macro.
13724 2001-11-13 Akim Demaille <akim@epita.fr>
13726 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13727 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13728 configure.ac.
13729 * tests/aclocal.m4: Remove, as it is no longer used.
13731 2001-11-13 Akim Demaille <akim@epita.fr>
13733 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13734 variable names when referring to a single test group, or to
13735 `suite' when referring to the whole test suite.
13736 `at_last_test' is removed: m4 compute at_format itself.
13737 (at_stdout, at_stder1, at_stderr): New variables.
13738 (AT_CHECK): Use them.
13740 2001-11-13 Akim Demaille <akim@epita.fr>
13742 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13743 in PATH.
13744 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13745 Do it as soon as a test fails, don't wait till the end of the test
13746 suite.
13747 Don't remove $as_me.[0-9]*, since these files no longer exist.
13749 2001-11-13 Akim Demaille <akim@epita.fr>
13751 * tests/tools.at: Use absolute paths, since we are no longer run
13752 in place.
13754 2001-11-13 Akim Demaille <akim@epita.fr>
13756 Now that tests are running in their own private dir, there is no
13757 need to list the files to remove at the end of tests groups.
13759 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13760 (AT_data_files, at_data_files): Remove.
13761 (AT_CLEANUP, AT_DATA): Simplify.
13762 (AT_INIT): Adjust.
13763 Remove the group dir if !debug && !failed.
13764 * tests/atspecific.m4: Adjust.
13766 2001-11-13 Akim Demaille <akim@epita.fr>
13768 Start a new layout for Autotest: `testsuite' creates
13769 `testsuite.dir' in which the at-check-line etc. files are to be
13770 found, and `testsuite.dir/003' where the test group 3 is run.
13772 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13773 at_check_line_file, at_format, at_test_normalized, at_group_dir
13774 are new variables.
13775 Create the directories.
13776 Use absolute paths for at- files.
13777 (AT_CHECK): Adjust.
13779 2001-11-11 Michael Matz <matz@kde.org>
13781 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13782 (m4_car2): New.
13783 (m4_car): Properly quote arguments.
13785 2001-11-13 Akim Demaille <akim@epita.fr>
13787 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13788 with stricter rules on LIBOBJS.
13790 2001-11-12 Paul Eggert <eggert@twinsun.com>
13792 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13793 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13794 __PROTOTYPES too.
13796 2001-11-12 Akim Demaille <akim@epita.fr>
13798 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13800 2001-11-12 Akim Demaille <akim@epita.fr>
13802 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13803 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13804 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13805 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13806 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13807 specify to what the macro should be defined (typically to 1).
13809 2001-11-12 Akim Demaille <akim@epita.fr>
13811 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13812 From Jim Meyering.
13814 2001-11-12 Akim Demaille <akim@epita.fr>
13816 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13817 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13818 definition used by Automake where LEX is +/- "${missing} lex" and
13819 `missing' itself contains variables.
13821 2001-11-12 Akim Demaille <akim@epita.fr>
13823 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13824 Now that M4sh pushes BODY, the comments were output at the end of
13825 the test suites.
13827 2001-11-08 Akim Demaille <akim@epita.fr>
13829 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13830 that we can trace macros from aclocal.m4.
13831 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13832 obsoleted, and redirect to the former anyway.
13833 Reported by Ralf Corsepius.
13835 2001-11-08 Akim Demaille <akim@epita.fr>
13837 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13838 processed only if present.
13839 * tests/torture.at (Configuring subdirectories): Use autoreconf
13840 instead of successive calls to autoconf.
13841 Add a nonexistent subdirectory to exercise the patch above.
13842 Reported by Ralf Corsepius.
13844 2001-11-08 Kevin Ryde <user42@zip.com.au>
13846 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13847 doesn't accept .S files.
13849 2001-11-07 Akim Demaille <akim@epita.fr>
13851 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13852 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13853 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13854 * bin/autom4te.in (warn_forbidden): New.
13855 (handle_output): Use it.

13867 From Nicolas Joly.
13869 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13871 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

13888 Use and export them.
13889 (&find_configure_ac): Optionally take a directory where to look at.
13890 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of

13901 Add basename, dirname, and fileparse.
13902 (@EXPORT): Adjust.
13903 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13904 Don't look for aclocal flags if we already know aclocal is not
13905 used.
13906 Move aclocal.m4t only if it exists.
13907 Reported by Ezra Peisach.
13909 2001-11-03 Akim Demaille <akim@epita.fr>
13911 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13912 passed on command line, defaulting to ./configure.ac if present.
13913 (&maybe_autoreconf, File::Find): Remove, unused.
13914 (&autoreconf): If autoconf is not used, don't try to trace.
13916 2001-11-02 Akim Demaille <akim@epita.fr>
13918 * configure.ac: Bump to 2.52g.
13920 2001-11-02 Akim Demaille <akim@epita.fr>
13922 Version 2.52f.
13924 2001-11-02 Akim Demaille <akim@epita.fr>
13926 * config/config.guess, config/config.sub, doc/standards.texi:
13927 * config/lispdir.m4: Update from masters.
13928 * configure.ac: Bump to 2.52f.
13930 2001-11-02 Akim Demaille <akim@epita.fr>
13932 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13933 Don't run aclocal when aclocal.m4 is not from aclocal.
13934 From Ezra Peisach.
13935 Don't run libtoolize and gettextize if --install is not given.
13937 2001-11-01 Paul Eggert <eggert@twinsun.com>
13939 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13940 be invoked before _AS_LINENO_PREPARE.
13941 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13942 than character ranges.
13944 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13945 invoking AS_BASENAME. Set the locale variables to 'C' if
13946 possible, as POSIX requires this to get the traditional
13947 behavior.
13948 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13950 2001-10-31 Paul Eggert <eggert@twinsun.com>
13952 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13953 with {}, as that triggers a bug in Bash 2.05.
13955 (_AS_LINENO_PREPARE): Use Sed rather than
13956 Awk. Fix the sed prepass to work even if there are multiple
13957 instances of $LINENO on the same line. Do not substitute for
13958 other variables like $LINENOT. Do not check file dates; such a
13959 check is unreliable on sufficiently fast machines, and removing
13960 the check makes the code simpler and more reliable. Check for
13961 output and chmod failures.
13963 * doc/autoconf.texi (Special Shell Variables): Document
13964 the above.
13966 2001-10-31 Akim Demaille <akim@epita.fr>
13968 * tests/Makefile.am (atconfig): Remove this target, Automake
13969 handles it now.
13971 2001-10-31 Akim Demaille <akim@epita.fr>
13973 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13974 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13975 provided, while it is optional.
13976 * configure.ac: Adjust.
13978 2001-10-26 Paul Eggert <eggert@twinsun.com>
13980 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13981 lib/Autom4te/Struct.pm:
13982 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13983 with 5.005_02.
13985 * doc/autoconf.texi (Special Shell Variables): Document some
13986 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13988 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13989 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13990 eval $LINENO is not portable in practice.
13992 2001-10-24 Akim Demaille <akim@epita.fr>
13994 * lib/Autom4te/General.pm (backname): New.
13996 2001-10-24 Akim Demaille <akim@epita.fr>
13998 * m4/: Remove, merged into...
13999 * config/: here.
14001 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14003 * doc/autoconf.texi (Shellology): Mention the problems with bash
14004 2.05's use of ANSI quoting in its `set' builtin.
14006 2001-10-22 Paul Eggert <eggert@twinsun.com>
14008 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14009 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14010 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14011 POSIX decided to standardize on the int flavor of strerror_r.
14012 Always do char* test, as there's no reason not to.
14013 Assign to a char* var, to catch strerror_r that returns int*.
14015 * doc/autoconf.texi (Particular Functions):
14016 Document the above changes. Also, document the fact that
14017 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14019 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14021 2001-10-20 Akim Demaille <akim@epita.fr>
14023 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14024 the executable was missing from the log.

14028 * lib/Autom4te/General.pm (&update_file): If destination is
14029 unchanged, remove the source.
14030 (&up_to_date_p): Don't be verbose, be debug.
14031 * bin/autoreconf.in: No longer support --m4dir.
14032 (&autoreconf): Display the full path of the configure.ac we are
14033 studying.
14034 Trace it only once.
14035 Be sure to honor --force with gettextize.
14036 Always run aclocal.
14037 * doc/autoconf.texi: Adjust.
14039 2001-10-20 Akim Demaille <akim@epita.fr>
14041 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14042 Remove, dead.
14043 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14044 `intl' is already present, as it refuses unless --force.
14045 (&parse_args): Use -I, --include instead of the old Autoconf
14046 options.
14047 ($localdir, $autoconf_dir): Remove.
14048 (@include): New.
14049 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14051 2001-10-19 Jens Petersen <petersen@redhat.com>

14059 file in @configure_input@.
14060 Don't mention `automatically' in addition to `generated'.
14061 * tests/torture.at (#define header templates): Adjust.
14063 2001-10-19 Akim Demaille <akim@epita.fr>
14065 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14066 comment, explain how to install automatic mode selection.
14067 From Russ Allbery.
14069 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14071 * bin/autoreconf.in (autoreconf): Display the path to the
14072 configure.ac being studied.
14074 2001-10-18 Paul Eggert <eggert@twinsun.com>
14076 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14077 long, to work around a bug in the HP C compiler version HP92453-01
14078 B.11.11.23709.GP.
14080 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14081 (AS_BASENAME_EXPR): New macro.
14082 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14083 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14084 and fall back on 'sed' only if the other two fail. This makes
14085 AS_BASENAME act more like AS_DIRNAME.
14086 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14087 contains white space.
14088 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14089 Use AS_DIRNAME, since I think it's now DOS-friendly.
14090 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14091 Allow "dirname //FOO" to return either / or //, as POSIX allows
14092 either behavior.
14094 2001-10-10 Akim Demaille <akim@epita.fr>
14096 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

14098 From Eric Sharkey.

14102 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14103 m4_define, since...

14142 bother with $force since...
14143 * lib/Autom4te/General.pm: does.
14145 2001-10-08 Akim Demaille <akim@epita.fr>

14221 * tests/tools.at (AT_DATA_FORBIDDEN): New.

14234 ourselves with CONFIG_SHELL.
14236 2001-10-05 Paul Eggert <eggert@twinsun.com>
14238 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

14242 2001-10-05 Akim Demaille <akim@epita.fr>
14244 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

14309 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14310 Don't use nested parenthesization. This patch was originally
14311 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
14312 but somehow it didn't get incorporated then.
14313 * doc/autoconf.texi (Limitations of Usual Tools):
14314 Clarify remark about sed and nested parenthesization.
14316 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):

14318 the type exists.
14319 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14320 Check for `expr' arithmetic overflow, and for compilation failure,
14321 and invoke a new argument $4 if either is discovered.
14322 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14323 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
14325 2001-09-28 Akim Demaille <akim@epita.fr>

14336 Output `AT_tested' only when existing.
14337 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
14339 2001-09-27 Akim Demaille <akim@epita.fr>
14341 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
14342 generates too many bug reports.
14344 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
14345 status when executing the ACTION-IF-FALSE.
14346 * tests/base.at (AC_TRY_*): Rename as...

14364 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
14365 Raja R Harinath:
14366 Be sure to detect when $LINENO always returns the same value.
14367 Look for the original script, basename($0) is certainly not
14368 enough.
14369 Pass the CLI arguments to `$as_me.lineno'.

14390 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
14391 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
14392 builddir, buildpath, top_builddir, and top_buildpath.
14393 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
14394 the current directory.

14407 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14408 Remove.

14419 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14420 (Programming in M4sh): this.

14464 * tests/Makefile.am (package.m4): Remove.
14466 2001-09-22 Akim Demaille <akim@epita.fr>
14468 Rely on `$LINENO' when possible instead of `__oline__'.
14470 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14471 `$LINENO' support replacement when not supported.
14472 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14473 them explicitly to be sure they are not output before this section
14474 (via m4_require). Cosmetic only.

14476 * lib/autoconf/programs.m4: Replace all the occurrences of

14480 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14482 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14483 character (u: -> ue) in a code comment.
14484 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14485 it works.
14487 2001-09-21 Akim Demaille <akim@epita.fr>
14489 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14490 Suggested by Jim Meyering.
14492 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14494 * lib/autoconf/programs.m4: Use extensions listed in
14495 $ac_executable_extensions when looking for programs.
14497 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14499 * lib/autoconf/general.m4: Fix a small Englisho.

14507 PATH_SEPARATOR.
14508 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14509 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should

14511 * lib/autotest/general.m4: Replace occurrences of ':' in
14512 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14514 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14516 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14517 arguments. Fixed a typo.
14519 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14521 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14522 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14524 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14526 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14527 * bin/autoupdate.in: Ditto.
14528 * bin/autoheader.in: Reworded a few comments.
14529 * bin/autoconf.in: Reworded help text for a few options.
14530 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

14533 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14535 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14536 already have $file). Set output files to binary mode (helps avoid
14537 CR issues on DOSish systems).
14539 2001-09-19 Akim Demaille <akim@epita.fr>
14541 * lib/autotest/general.m4: Englishoes.
14542 From Tim Van Holder and Alexey Mahotkin.
14544 2001-09-18 Paul Eggert <eggert@twinsun.com>
14546 * doc/autoconf.texi (Common Shell Constructs): New node,
14547 documenting AS_DIRNAME.
14548 (Limitations of Usual Tools): Refer to it when discussing dirname.
14549 Also, update discussion of POSIX standard to reflect latest draft.
14551 * lib/autoconf/c.m4:
14552 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14554 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14555 Do not pass a first argument with leading '-'
14556 to expr, by parenthesizing initial integers that might be negative.
14558 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14559 now merely checks whether it is an error to pass an argument
14560 to getpgrp.
14562 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14563 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14564 whether it is a (compile-time) error to pass an argument to
14565 getpgrp. This simpler test supports the revised documentation,
14566 and is all that AC_FUNC_GETPGRP's users really need.
14568 2001-09-18 Akim Demaille <akim@epita.fr>
14570 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14572 2001-09-18 Akim Demaille <akim@epita.fr>

14580 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14581 correctly.
14582 Add test for AS_BASENAME.
14583 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14584 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14585 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14586 * tests/base.at: Fixed the expected responses. The old ones were
14587 one line out...
14588 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14589 the documentation claims it should (and how it behaved in 2.13).
14591 2001-09-18 Akim Demaille <akim@epita.fr>
14593 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14594 the AC_CONFIG_COMMANDS invocation.
14595 This also solves the name clash problems.
14596 Don't set the package's ID.
14597 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14598 No longer to be shipped.
14599 (version.in): Remove.
14600 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14601 * lib/autoconf/status.m4: Adjust.
14602 Use `m4_PACKAGE_STRING'.
14603 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14604 the only optional argument is the name of the test suite.
14605 Expect `package.m4' to define the package signature.
14606 * lib/autom4te.in (Autotest): Add `package.m4?'.
14607 * tests/Makefile.am (package.m4): New.
14608 * tests/suite.at: ifnames is a victim.
14610 2001-09-18 Akim Demaille <akim@epita.fr>
14612 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14613 AC_LIBSOURCE, AC_CONFIG_FILES.
14614 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14615 program version string doesn't match the package's.
14616 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14617 after `(cached)'.
14619 2001-09-17 Paul Eggert <eggert@twinsun.com>
14621 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14622 Allow expression to return any value that can fit into unsigned long
14623 (not int, as before). Check for output errors.
14625 2001-09-17 Bruno Haible <haible@ilog.fr>
14627 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14628 Always include <stdio.h> and <stdlib.h>. Evaluate
14629 the expression in an extra function before these includes. Call
14630 fprintf "%d" only after ensuring the argument is of type 'int'.
14631 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14633 2001-09-17 Paul Eggert <eggert@twinsun.com>
14635 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14636 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14637 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14638 when they don't exist.
14640 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14641 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14642 need it.
14644 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14645 version with the version used by fileutils 4.1, except use
14646 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14647 we don't need it.
14649 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14651 2001-09-13 Akim Demaille <akim@epita.fr>
14653 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14654 _first_.
14655 Reported by Gerrit P. Haase.
14657 2001-09-13 Akim Demaille <akim@epita.fr>
14659 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

14666 Use it.

14672 (m4_re_escape): New.
14673 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
14674 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14675 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14676 Likewise.
14677 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14678 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14679 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14680 AT_tests_all for consistency.
14681 Set at_victims.
14682 (AT_VICTIMS): Similar to AT_KEYWORDS.
14683 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14685 2001-09-13 Akim Demaille <akim@epita.fr>
14687 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14689 2001-09-13 Akim Demaille <akim@epita.fr>
14691 * lib/autotest/general.m4 (AT_INIT): Create and remove
14692 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14693 test suites can cohabit.
14695 2001-09-13 Akim Demaille <akim@epita.fr>
14697 * tests/mktests.sh: Don't output banners for empty test files.
14699 2001-09-13 Akim Demaille <akim@epita.fr>
14701 Test suites can be run independently of configure.
14703 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
14704 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

14716 (Syntax of the shell scripts): Don't check ifnames.
14717 (AT_CHECK_PERL_SYNTAX): New.
14718 (Syntax of the Perl scripts): Check ifnames.
14719 * tests/ifnames: New.

14737 (_AT_CLEANUP_FILE_IF, _AT_CLEANUP_FILE): these.
14738 (_AT_CLEANUP_FILE_IF): Simplify the regexp.
14739 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
14740 No longer fill the HELP diversion.
14741 (AT_CLEANUP): Use them.
14742 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
14743 (m4_list_append): Remove.
14745 Spread a few keywords in the Autoconf test suite.
14747 2001-09-10 Akim Demaille <akim@epita.fr>
14749 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14762 * tests/semantics.at (AC_PATH_PROG & AC_PATH_PROGS)
14763 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
14765 2001-09-07 Akim Demaille <akim@epita.fr>
14767 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
14768 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
14769 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
14770 related variables into `at_package_*'.
14771 * lib/autotest/general.m4 (AT_VICTIMS): New.
14772 (AT_INIT): Adjust for stand-alone/embedded test suites.
14773 (AS_MESSAGE_LOG_FD): Define and use it.
14774 * tests/suite.at (AT_VICTIMS): Use it.
14775 * tests/tools.at (autoupdating AC_PREREQ): Don't depend upon
14776 at_version.
14778 2001-09-07 Akim Demaille <akim@epita.fr>
14780 Move toward possibly stand-alone test suites.
14782 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
14783 in addition, it introduces useless differences in logs.
14784 (AT_INIT): Let atconfig and atlocal be both optional.
14785 Adjust PATH computation.
14786 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
14788 2001-09-07 Akim Demaille <akim@epita.fr>
14790 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon
14791 m4sugar/version.m4.
14793 2001-09-05 Akim Demaille <akim@epita.fr>
14795 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

14797 From Uwe Seimet.
14799 2001-09-05 Akim Demaille <akim@epita.fr>
14801 * bin/autom4te.in: --language is -l, not -s.
14803 2001-09-05 Akim Demaille <akim@epita.fr>
14805 Be ready to handle filenames as stupid as `dnl.at', for if even
14806 the maintainer is dumb enough to do that...
14808 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14809 excellence in M4 quotation: consider `__file__' is active.
14811 And BTW, when invoking m4, pass the --include in the right order:
14812 the wrong one.
14814 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14815 4m.
14817 2001-09-05 Akim Demaille <akim@epita.fr>
14819 * lib/Autom4te/XFile.pm: New lib file.
14820 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
14821 * bin/autoheader.in: Use it.
14823 2001-09-05 Akim Demaille <akim@epita.fr>
14825 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
14826 defined.
14828 2001-09-05 Akim Demaille <akim@epita.fr>
14830 * lib/Autom4te/General.pm (&getopt): Work around the `-' Getopt bug.
14831 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.
14833 * bin/autoscan.in: Use `getopt' and `find_files' etc.
14834 Add -I, --include support.
14835 * doc/autoconf.texi (autoscan Invocation): Adjust.
14837 2001-09-05 Akim Demaille <akim@epita.fr>
14839 CVS GNU M4 doesn't like `undefine(undefined)'.
14841 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14842 New, extracted from main.
14843 Use IO::File wherever possible.
14844 (input.m4): Be constant, use -I instead of hard coding $tmp.
14845 Therefore be a quoted heredoc.
14846 Don't invoke `_au_disable', since ac was not loaded, but just
14847 `unm4.m4'.
14849 2001-08-31 Akim Demaille <akim@epita.fr>
14851 Version 2.52d.
14853 2001-08-31 Akim Demaille <akim@epita.fr>
14855 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
14856 previous patch.
14857 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
14859 2001-08-31 Akim Demaille <akim@epita.fr>
14861 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
14862 serious problems handling heredocs in heredocs.
14863 Reported by Nicolas Joly.
14865 2001-08-31 Akim Demaille <akim@epita.fr>
14867 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
14868 (Making testsuite Scripts): Update.
14870 2001-08-31 Akim Demaille <akim@epita.fr>
14872 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
14874 2001-08-31 Akim Demaille <akim@epita.fr>
14876 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14877 (testsuite Scripts): There is no such thing as `atconfig.in'.
14878 And actually one diagram is missing: test suite runtime.
14880 2001-08-31 Akim Demaille <akim@epita.fr>
14882 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14883 inverse order.
14885 2001-08-31 Akim Demaille <akim@epita.fr>
14887 * bin/autoupdate.in (@include): `installcheck' revealed the path
14888 to m4sugar was lacking!
14890 2001-08-31 Akim Demaille <akim@epita.fr>
14892 * man/Makefile.am (.x.1): We really have to pass
14893 autom4te_perllibdir.
14895 2001-08-31 Akim Demaille <akim@epita.fr>
14897 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14898 debug scripts, in particular passing explicitly listed tests to
14899 run is stupid.
14901 2001-08-31 Akim Demaille <akim@epita.fr>
14903 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14904 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14905 Use directly autom4te, not autoconf.
14906 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
14908 2001-08-31 Akim Demaille <akim@epita.fr>
14910 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
14911 * bin/autoheader.in (%symbol): Strip arguments of macros.

14917 2001-08-31 Akim Demaille <akim@epita.fr>
14919 * bin/autom4te.in (&parse_args): Die on unknown languages.
14920 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14921 need for autoconf.
14922 Promote --include over --macrodir and other obsolete options.
14924 2001-08-31 Akim Demaille <akim@epita.fr>
14926 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
14927 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
14928 * bin/autom4te.in ($autoconf): Pass --force.
14929 `print $out' doesn't print `$_' but `$out'.
14930 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14931 (autoheader): Pass --force since the test suite goes too fast for
14932 the time stamps.
14933 Adjust to the new autoheader messages.
14935 2001-08-31 Akim Demaille <akim@epita.fr>
14937 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14938 Check the completeness of the #template.
14939 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
14940 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
14941 invocation.
14943 2001-08-31 Akim Demaille <akim@epita.fr>
14945 * lib/Autom4te/General.pm (&find_file, &update_file): New.
14946 * bin/autoupdate.in, bin/autoheader.in: Adjust.
14947 Drop AC_MACRODIR dead for real.
14948 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14949 `autoheader: `config.hin' is created'.
14950 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14952 2001-08-31 Akim Demaille <akim@epita.fr>
14954 * bin/autoheader.in: Rewrite in Perl.
14955 * tests/autoheader: Adjust.
14957 2001-08-31 Akim Demaille <akim@epita.fr>
14959 * bin/autoconf.in (--include, -I): New option.
14960 Map --localdir, --autoconf-dir onto it.
14961 Forward autom4te's options instead of interpreting them.
14962 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14963 There is no such envvar since the inception of autom4te.cfg.
14964 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14965 * bin/autoupdate.in: Adjust, and perform more control.
14966 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
14967 * tests/autoconf: Dittowise.
14969 2001-08-31 Akim Demaille <akim@epita.fr>
14971 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14972 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14973 optionally `FILE'.
14974 Use -e, not -f, since /dev/null for instance is OK.
14975 (&parse_args): Adjust.
14976 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14978 2001-08-31 Akim Demaille <akim@epita.fr>
14980 * configure.ac: Also find tested executables in bin.
14981 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14982 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14983 installed peer executables, only PATH is allowed to resolve it.
14984 Pass `autoconf_dir' via options, not via invisible envvars.
14985 * lib/Autom4te/General.pm (&find_peer): Remove.
14986 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14987 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14988 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14989 find the executables for it.
14990 * tests/Makefile.am: Major cleanup. Too lazy to document...
14991 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14992 We only need PERL.
14993 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14994 indeed related to running the test suite, while passing
14995 --autoconf-dir and others is related to running non installed
14996 Autoconf executables. So don't do that, leave it to...
14997 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14998 * tests/autoscan: New.
14999 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15000 refer to library files: rely on --language.
15002 2001-08-29 Akim Demaille <akim@epita.fr>
15004 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
15005 s/--set/--language/.
15007 2001-08-29 Akim Demaille <akim@epita.fr>
15009 * doc/autoconf.texi: Strip the @nodes.
15010 Suggested by Paul Eggert.
15011 (Initializing configure): Typo.
15013 2001-08-29 Akim Demaille <akim@epita.fr>
15015 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15016 Suggested by Paul Eggert.
15018 2001-08-29 Akim Demaille <akim@epita.fr>
15020 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15021 download in a tmp dir.
15023 2001-08-29 Akim Demaille <akim@epita.fr>
15025 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15026 case insensitive OSes out there :(
15027 From Tim Van Holder.
15029 2001-08-29 Akim Demaille <akim@epita.fr>
15031 * lib/autom4te.in: New.
15032 * lib/Makefile.am (edit, autom4te.cfg): New.
15033 * bin/autom4te.in (BEGIN): Simplify.
15034 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
15035 (&load_configuration): New. Use it.
15036 (&parse_args): Support --mode, --set, and --melt.
15037 * bin/autoconf.in: Simplify and adjust.
15038 * tests/Makefile.am (AUTOMAKE): Use --set.
15039 * tests/atlocal.in: Adjust.
15040 * BUGS: distcheck and check are weak.
15042 2001-08-29 Akim Demaille <akim@epita.fr>
15044 * lib/autotest/general.m4: Use
15045 foo=`(command) 2>/dev/null`
15046 not
15047 foo=`command` 2>/dev/null
15048 (at-devnull): Rename as...
15049 (AT-devnull): this.
15050 (--clean): Remove AT-* files too.
15051 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15052 Reported by Nicolas Joly.
15054 2001-08-28 Akim Demaille <akim@epita.fr>
15056 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
15057 quotes inside single quotes.
15058 Reported by Nicolas Joly.
15060 2001-08-28 Kevin Ryde <user42@zip.com.au>
15062 * doc/autoconf.texi (Function Portability): Mention C right shifts.
15064 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
15066 * lib/autotest/general.m4: Reword some messages.
15067 (AT_INIT): Check for the `times' builtin before using it.
15068 Support test ranges as arguments to the testsuite.
15069 Have -e imply -d as the help text suggested.
15071 2001-08-27 Akim Demaille <akim@epita.fr>
15073 * Makefile.maint: Formatting changes.
15074 (do-po-update, po-update, cvs-update, update): New targets.
15075 (AMTAR): Remove.
15077 2001-08-27 Akim Demaille <akim@epita.fr>
15079 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

15082 <AUTOTEST_PATH>: May contain absolute dir names.
15084 2001-08-27 Akim Demaille <akim@epita.fr>
15086 * lib/autotest/general.m4 (AT_INIT): Log the command line.
15087 Support `VAR=VAL' as arguments.
15088 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
15089 may be set via the command line.
15091 2001-08-27 Akim Demaille <akim@epita.fr>
15093 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
15094 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
15095 first the build dirs, then the src dirs.
15096 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
15098 2001-08-27 Akim Demaille <akim@epita.fr>
15100 * lib/autotest/general.m4 (AT_INIT): Output the definition of
15101 at_data_files earlier.

15105 2001-08-27 Akim Demaille <akim@epita.fr>
15107 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
15108 `ac_top_builddir' to mimic Automake's vocabulary, which much more
15109 readable.
15110 Adjust callers.
15111 * doc/autoconf.texi (Configuration Actions): Document the vars
15112 available in commands.
15113 Emphasize the risks of collisions in init-cmds.
15115 2001-08-27 Akim Demaille <akim@epita.fr>
15117 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
15118 (Initializing configure): this new node.
15120 2001-08-27 Akim Demaille <akim@epita.fr>
15122 * Makefile.am (EXTRA_DIST): INSTALL.txt is a dead hack.

15133 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
15134 to...
15135 * lib/autoconf/autoheader.m4: this new file.
15136 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)

15141 2001-08-27 Akim Demaille <akim@epita.fr>
15143 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
15144 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15145 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15146 -> ac_dir).
15147 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15148 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
15150 2001-08-27 Akim Demaille <akim@epita.fr>
15152 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

15175 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
15176 (AMTAR): Help automake define it.
15177 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15178 needed, 1.5 can have a macro and a target with the same name.
15179 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15180 * m4/strip.m4: New.

15193 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
15194 Adjust callers.
15195 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15196 the name of the directory they're in, instead of the filename,
15197 since version.m4 is now in m4sugar, but m4_acversion must not be
15198 classified as an Autoconf macro.
15199 ($input_m4): Don't qualify the path to m4sugar.
15200 Rather, pass autoconf_dir to m4.
15201 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15202 * tests/suite.at: Require 2.52c.
15204 2001-08-27 Akim Demaille <akim@epita.fr>

15289 2001-08-20 Akim Demaille <akim@epita.fr>
15291 Info readers seem to need `Index' in the index node title :(
15293 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15294 simplified index node names.

15338 2001-08-20 Akim Demaille <akim@epita.fr>
15340 Huh!?!?! There are still some user EOF tags used, which prevents
15341 their use in AC_CONFIG_COMMANDS for instance...
15343 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15344 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

15407 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

15423 2001-08-17 Akim Demaille <akim@epita.fr>
15425 * doc/autoconf.texi: Work around Texinfo buglets.
15426 (Transformation Rules): One example is enough, users are expected
15427 to have their brains on. And BTW, use DESTDIR.
15428 (dvar): New macro. Use it.
15430 2001-08-17 Akim Demaille <akim@epita.fr>
15432 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15472 value.

15477 * Makefile.maint (CVS): New.
15478 (local-check): Run changelog-check. last.
15479 (alpha): Don't depend upon local-check, since...
15480 (cvs-dist): depends upon it.
15482 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15484 * tests/Makefile.am: Use a clean-local rule to remove
15485 autom4te.cache (it's a directory, not a file.
15486 * Makefile.am: Ditto (but maintainer-clean-local).
15488 2001-08-15 Akim Demaille <akim@epita.fr>
15490 * bin/autom4te.in (@m4_warning): New.
15491 (&handle_m4): Use it.
15492 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15493 warnings are issued at each run.
15494 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15495 is in the src tree.
15497 2001-08-15 Akim Demaille <akim@epita.fr>

15500 don't waste time running `autoupdate --version' works.
15501 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15503 2001-08-13 Akim Demaille <akim@epita.fr>
15505 * doc/autoconf.texi (ma): Rename this index as...
15506 (ac): this.

15528 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15529 to the INSTALL file.

15556 * tests/mktests.sh: Update year in copyright notice.
15558 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15560 * tests/semantics.at (AC_C_BIGENDIAN): New test.
15562 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15564 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15565 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15566 * doc/autoconf.texi (C Compiler Characteristics): Update
15567 documentation for AC_C_BIGENDIAN.
15569 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15571 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15572 magic values from an object file when cross-compiling.
15573 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15575 2001-08-10 Akim Demaille <akim@epita.fr>
15577 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15578 effects.
15579 Suggested by Russ Allbery.
15581 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15583 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15584 current $prefix to the sub-configures.
15586 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15588 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15589 extension (needed on BeOS). Reported by Guido van Rossum.
15591 2001-08-09 Akim Demaille <akim@epita.fr>
15593 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15595 2001-08-07 Akim Demaille <akim@epita.fr>
15597 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15598 removed.
15599 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15600 No need to remove the files before and after the each test, before
15601 each test and at the end of the suite is enough.
15602 Display only the children `times', not the shell's.
15603 If the test failed or was skipped, at-times is not available.
15605 2001-08-07 Akim Demaille <akim@epita.fr>
15607 Always produce testsuite.log, including when there are no
15608 failures. This helps getting information on skipped tests, and
15609 duration of the tests. Err, implement the latter btw.
15611 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15612 Dump information on the first run of each test.
15613 (AT_CLEANUP): Create `at-times' containing the duration of the
15614 test group.
15616 2001-08-07 Akim Demaille <akim@epita.fr>
15618 The use of `dumpstat' revealed that `len' was used although it
15619 should not. m4_text_wrap was using it, but in the Autoconf world
15620 where it is legal. Hence (i) test M4sh in its own world, not
15621 Autoconf's, and (ii), ahem, fix the bug :)
15623 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15624 does not like `' instead of [].
15625 (AT_INIT): Forbid `^_?AT_'.
15626 And don't output such tokens.
15627 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15628 `script.as', and `autom4te.cache'.
15629 Remove `empty' and `macro' which are no longer used.
15630 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15631 * tests/m4sugar.at: Use it.
15632 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15634 2001-08-07 Akim Demaille <akim@epita.fr>
15636 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15638 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15640 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15642 2001-08-04 Akim Demaille <akim@epita.fr>
15644 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15645 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15646 AC_TRY_LINK.
15647 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15648 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15649 (AC_F77_MAIN): Likewise.
15651 2001-08-04 Akim Demaille <akim@epita.fr>
15653 Don't rely on M4sugar outputting the patterns in files, since we
15654 might process the output _without_ running m4, hence without these
15655 files.
15657 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15658 * bin/autom4te.in (@Request::includes): Remove, unused.
15659 (@Request::source): Rename as...
