1473 overridden by $MAKE. Document this in --help output.
1474 * doc/autoconf.texi (autoreconf Invocation): Document
1475 all environment variables honored by autoreconf.
1476 * NEWS: Update.
1477 Report by Paul Eggert.

1481 Documentation improvements.
1482 * doc/autoconf.texi (Looping constructs): s/recurses/repeats/.
1483 (Evaluation Macros): Drop `1' suffix from metasyntax variable name
1484 that preceeds @dots. Improve wording.
1485 (Text processing Macros): Drop `1' suffix from metasyntax variable
1486 name that preceeds @dots.
1487 (Number processing Macros): Drop `1' suffix from metasyntax
1488 variable name that preceeds @dots. Improve wording.
1489 * lib/m4sugar/m4sugar.m4 (m4_cmp): Comment wording fix.
1490 Suggested by Ralf Wildenhues.
1492 2008-03-02 Jim Meyering <meyering@redhat.com>
1494 Don't infloop upon "make dist".
1495 * GNUmakefile: Merge from coreutils.
1496 * Makefile.am (dist-hook): Inject .tarball-version into tarball,
1497 not .version.
1498 * configure.ac (AC_INIT): Use .tarball-version, not .version.
1499 * build-aux/git-version-gen: Update from gnulib.
1501 2008-03-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1503 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1504 Before using /dev/full, check that it is a writable character
1505 special device.
1506 Report by Benoit Sigoure and Eric Blake.

1519 (autotools and whitespace in file names): Use them.
1520 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1521 Cover more potentially problemtic file names. Use the new
1522 functions.
1524 Properly handle funny file names for headers in config.status.
1525 The test suite did not cover this bug because the code was not
1526 quoting properly the arguments of `rm -f' (which "fails" silently)
1527 as well as the arguments of `diff' (whose output was redirected to
1528 /dev/null so we couldn't see its error message).
1529 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
1530 file names passed to `rm' and `diff'.
1531 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1532 Add a regression test.
1534 2008-03-01 Benoit Sigoure <tsuna@lrde.epita.fr>
1535 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1537 Properly expand @configure_input@ in config.status.
1538 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_MAIN_LOOP):
1539 Escape the backslashes and ampersands in $configure_input before
1540 using it in the sed replacement string to expand @configure_input@.
1541 Report by Eric Blake and Patrick Welche.
1543 2008-03-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1545 Ignore errors from ./run on w32.

1597 Fix more autotest regressions.
1598 * lib/autotest/general.m4 (AT_LINE): Fix regression from

1616 bug.
1618 * doc/autoconf.texi (Limitations of Builtins) <.>: Mention bash
1619 bug.
1621 2008-01-28 Eric Blake <ebb9@byu.net>
1623 Fix regression in handling VAR=VALUE arguments to testsuite.
1624 * lib/autotest/general.m4 (AT_INIT) <PARSE_ARGS_END>: Detect
1625 leading = as invalid. Defer use of command-line variable
1626 assignments...
1627 <PREPARE_TESTS>: ...here, after atconfig has been sourced. Fix
1628 regression in sourcing files.
1629 * tests/autotest.at (Using atlocal): New test to catch this.
1630 (Debugging a successful test, Choosing where testsuite is run):
1631 Use correct shell.

1640 forks when sanitizing PATH. Always output machine information,
1641 not just when atconfig was located.
1643 Add 'testsuite -C dir'.
1644 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1645 detection...
1646 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1647 argument.
1648 <DEFAULTS>: Delay computation of variables based on $at_dir...
1649 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1650 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1651 <PARSE_ARGS>: Parse new option.
1652 <HELP_TUNING>: Document it.
1653 * tests/autotest.at (Choosing where testsuite is run): New test
1654 for this feature.
1655 (Keywords and ranges): Add test for missing -k argument.
1656 * NEWS: Document this.
1657 * doc/autoconf.texi (testsuite Invocation): Likewise.
1659 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1661 * build-aux/config.guess, build-aux/config.sub,
1662 build-aux/texinfo.tex: Sync from gnulib.
1663 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1664 Likewise.
1666 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1668 * doc/autoconf.texi (Particular Programs): Do not mention the
1669 Autoconf version in which the AC_PROG_INSTALL change was done.
1670 Suggested by Paul Eggert.
1672 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1674 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1675 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1676 mode, we change to the source directory, also set $ac_pwd so we
1677 do not go back to the build tree for the next config subdir.
1678 * tests/torture.at (Deep Package): Extend test to contain two
1679 config subdirs on the top level.
1681 Fix parallel `maintainer-check'.
1682 * Makefile.am (maintainer-check-tests): Depend on `all'.
1683 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1684 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1685 Likewise.
1686 (maintainer-check): Serialize the testsuite runs.
1688 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'

1710 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1712 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1713 check_SCRIPTS. Building the wrappers for `all' allows help2man
1714 to use them for the manpages.
1715 Report by Benoit Sigoure.
1717 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1719 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1721 Fix some write failure cases in Autotest.

1726 script executable if it is not complete.
1728 2007-12-12 Eric Blake <ebb9@byu.net>
1730 Fix thinko in earlier patch - m4_join isn't defined yet.
1731 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1732 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1733 (m4_require): Use m4_do, not m4_join.
1735 Fix some whitespace tests on cygwin.
1736 * tests/tools.at (autom4te and whitespace in file names): Restore
1737 font-lock. Create $TMPDIR before it might be used.
1739 Fix spurious testsuite failure with M4 1.4.11.
1740 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1742 Optimize AC_REQUIRE.
1743 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1744 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1745 (m4_require): Avoid extra macro calls.
1747 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1749 * tests/torture.at (srcdir): Fix quoting.
1751 Do not pass top_srcdir to configure scripts in testsuite.
1752 * tests/autotest.at (srcdir propagation): Copy install-sh to
1753 source tree.
1754 (my only test): Drop setting of `top_srcdir'.
1755 * tests/base.at (Input/Output): Likewise.
1756 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1757 config.guess, and config.sub to test source tree.
1758 Drop AC_CONFIG_AUX_DIR setting.
1759 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1760 * tests/torture.at (Substitute a 2000-byte string): Drop
1761 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1762 (Substitute a newline, datarootdir workaround): Likewise.
1763 (Define a newline): Adjust for linenumber changes in configure.ac.
1764 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1766 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1767 if `pwd` contains whitespace.
1769 Quote $abs_top_srcdir in tests.
1770 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1771 * tests/tools.at (Syntax of the shell scripts): Likewise.
1773 * tests/m4sh.at (LINENO): Quote $0.
1775 Fix testsuite program wrapper for whitespace in `pwd`.
1776 The problem here is that the usual mantra is that command
1777 variables can contain arguments, thus we cannot just escape
1778 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1779 $top_builddir/tests directory early in $PATH, so that the
1780 wrappers are found by their plain name.
1781 * tests/wrapper.as: Put $testdir early in $PATH.
1782 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1784 Proper config.status --file/--header and $srcdir escaping.
1785 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1786 characters in $ac_file_inputs.
1787 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1788 accordingly.
1789 * tests/torture.at (datarootdir workaround): Adjust.
1790 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1792 Fix Autotest for whitespace in `pwd`.
1793 * lib/autotest/general.m4 (AT_INIT)
1794 <at_func_create_debugging_script, Driver Loop>:
1795 Quote $at_group_dir.
1796 * tests/autotest.at (whitespace in absolute testdir): New test.
1798 * lib/autom4te.in: Quote @datadir@.
1800 Proper file name escaping in Autoconf programs and Perl modules.
1801 This includes escaping of characters special to the shell
1802 as well as special to Perl, e.g., leading `<' or `>'.
1803 For example, when $file starts with `>', `open ">$file"'
1804 wrongly tries to append to a different file.
1805 * bin/autoconf.as: Fix quoting for autom4te options.
1806 * lib/Autom4te/General.pm (shell_quote): New function, taken
1807 from coreutils, written by Jim Meyering.
1808 (mktmpdir): Use it.
1809 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1810 and open_quote.
1811 * bin/autoreconf.in (parse_args): Likewise.
1812 * bin/autoscan.in (main): Likewise.
1813 * bin/autoupdate.in (main): Likewise.
1814 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1815 * bin/ifnames.in: Likewise, XFile usage fixes.
1816 * tests/tools.at (autom4te and whitespace in file names): Extend
1817 test. Test twice, with special characters allowed on w32, and the
1818 rest. Test leading and trailing whitespace, for `open_quote'.
1819 (autotools and whitespace in file names): New, analogous test.
1820 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1821 by Russ Allbery and Eric Blake.
1823 Sync from Automake.
1824 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1825 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1826 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1827 (update_file, contents): Use it.
1829 * Makefile.am (autom4te-update): Rewrite for git.
1831 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1833 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1835 Fix copyright years.
1836 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1837 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1839 2007-12-04 Eric Blake <ebb9@byu.net>
1841 Manually resync with gnulib, since 'make cvs-update' no longer works.
1842 * build-aux/config.guess: New upstream version.
1843 * build-aux/config.sub: Likewise.
1845 When using older automake, don't downgrade build-aux/texinfo.tex.
1846 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1847 * doc/Makefile.am (TEXINFO_TEX): Add.
1849 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1851 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1852 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1853 #undef as this runs afoul of our new way of creating config.h.
1854 Problem reported by Jim Meyering in
1855 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1857 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1859 Fix autom4te for unusual characters in input file names.
1860 * bin/autom4te.in (files_to_options): Quote active characters
1861 for the shell.
1862 * tests/tools.at (autom4te and white space in file names):
1863 New test.
1865 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1866 Document that Tru64 awk always splits $0.
1868 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1870 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1871 `#AT_STOP_...' line at the end of each test.
1873 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1875 * lib/autotest/general.m4 (AT_INIT): For awk line number
1876 extraction script, ensure `$at_group' has a defined value
1877 even for the empty set, and properly quote its usage inside
1878 the awk script.
1880 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1882 * doc/autoconf.texi (Shell Functions): New chapter. Document
1883 IRIX sh $0 issue in functions, move content from ...
1884 (Portable Shell): ... here.
1885 (Shell Script Compiler): Note that shell functions are not
1886 totally unportable any more.
1888 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1889 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1891 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1892 extracting the line numbers of the last needed test.
1894 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1896 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1897 Fix quoting.
1899 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1901 Fix IRIX testsuite debugging failures: $0 in functions.
1902 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1903 Do not use $0 inside a function, as IRIX sh will set that to the
1904 function name rather than the script invocation name.
1906 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1907 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1909 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1910 to extract test scripts.
1911 (AT_INIT): Extract and cache test script line numbers.
1913 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1915 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1916 subsequent fixups; the awk -> here-document conversion trashes
1917 performance too much with AIX sh.
1919 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1921 * tests/local.at: Do not test m4, perl with AT_TESTED.
1923 Diagnose and guard against write errors dealing with config.status.
1924 The general idea is this: all write failures from `configure'
1925 writing `config.status' are indicated by $ac_write_error, which
1926 is only checked at the end. This is safe because config.status
1927 code is not executed before the file is complete. Other write
1928 failures, be they inside config.status, or in sub shell/awk
1929 scripts spawned from configure or config.status, typically need
1930 earlier checking, as their results are used right afterwards.
1931 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1932 before writing config.status, check afterwards.
1933 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1934 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1935 Set `ac_write_error' for write failures to config.status. Barf
1936 upon write failures to temporary files.
1937 Adjust note about closing and reopening the here-document.
1938 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1939 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1940 reopening the here-document.
1941 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1942 Ensure `ac_write_error' does not escape into config.status.
1943 Also, add a couple of code paths not yet exercised in the test
1944 suite: a config file with input from stdin, and a config header
1945 output to stdout.
1946 Suggestion for catching write errors by Bruno Haible.
1948 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1950 Avoid error with Tru64 awk and testsuite lines with many words.
1951 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1952 reads the testsuite, set the field separator to an unusual value,
1953 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1954 even splits the input if $i, i>0, was never accessed in the script.
1956 Revert 2007-10-17 change.
1957 * TODO: Multiline args in config files and headers mean something
1958 different and are not fixed, see
1959 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1960 Report by Stepan Kasal.
1962 * doc/autoconf.texi (Generic Programs): Fix typo.
1964 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1966 AC_*_TOOL does not canonicalize the prefix
1967 * doc/autoconf.texi (Generic Programs): Do not say that
1968 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1970 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1972 Diagnose write errors in config.status instantiations.
1973 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1974 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1975 on write errors.
1976 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1977 Extend test to also check for some write error failures, using...
1978 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1979 Report by Bruno Haible.
1981 Indentation fixups.
1982 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1983 indentation.
1984 (_AT_CHECK): Use less indentation, to save space.
1986 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1988 Add witness macro for @top_build_prefix@ substitution.
1989 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1990 (_AC_OUTPUT_FILE): Mention it here.
1992 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1993 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1995 * lib/autotest/general.m4 (at_func_test): Remove.
1996 (AT_INIT): Pre-extract test groups into separate files.
1997 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1998 Remove at-test-source files together with the $at_group_dir.
1999 * tests/autotest.at (Long test source lines): New test.
2001 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2003 Shell functions and variables may share a namespace.
2004 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2005 limitation.
2007 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2009 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2010 gnulib.
2012 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2014 * lib/autoconf/status.m4: Fix a couple of comment typos.
2016 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2018 2007-11-13 Jim Meyering <meyering@redhat.com>
2020 Clean up the rule to create "expr".
2021 * tests/Makefile.am (expr): Don't redirect directly to target.
2022 Redirect just once, not for each echo statement.
2023 Use $@, not literal "expr".
2025 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2027 Don't worry about preprocessor when testing long long.
2028 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2029 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2030 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2031 These no longer check for preprocessor flaws.
2032 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2033 Do not check for preprocessor flaws.
2035 2007-11-13 Jim Meyering <meyering@redhat.com>
2037 Adapt dependencies, now that a version change doesn't modify configure.ac
2038 * GNUmakefile: Remove "make clean" kludge.
2039 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2040 configure.ac.
2041 Don't redirect directly to target.
2042 Use $@, not literal "version.m4".
2044 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2046 * doc/autoconf.texi (Making testsuite Scripts): Document
2047 ":;{" shorthand as in previous patch.
2049 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2051 * doc/autoconf.texi (Limitations of Builtins): Document problem
2052 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2053 for the workaround.
2054 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2055 Use ":;{" shorthand.
2056 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2058 2007-11-12 Jim Meyering <meyering@redhat.com>
2060 Add more non-srcdir build support.
2061 * GNUmakefile (dummy): Split a long line.
2062 Add -v option to autoreconf invocation.
2064 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2065 * GNUmakefile (dummy): Remove INSTALL.
2067 Remove racy commands to build scripts in bin/ and tests/.
2068 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2069 are guaranteed to be built, remove the rules that tried to build
2070 them. Before, with a parallel build, these rules could lead to
2071 two processes writing tests/wrapper.in concurrently.
2073 Build in man/ only *after* building in bin/ and tests/.
2074 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2075 in both bin/ and tests/.
2077 Accommodate non-srcdir build-from-checkout.
2078 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2079 Use git's --git-dir=$srcdir/.git option.
2080 Add quotes, in case tarball_version_file contains shell meta-characters.
2081 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2082 * configure.ac: Pass "." to git-version-gen.
2084 Avoid spurious test failures due to version skew.
2085 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2087 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2089 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2090 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2091 Remove conftest.dSYM directory.
2092 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2093 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2094 Remove `conftest.*' recursively.
2095 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2096 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2097 Likewise.
2098 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2099 * THANKS: Update.
2100 Report and analysis by Jeff Squyres and Peter O'Gorman.
2102 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2104 Fix typos in variable names.
2105 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2107 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2109 Document that $((expression)) is not portable.
2110 * doc/autoconf.texi (Shell Substitutions): Here.
2112 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2114 Ignore configure --help* errors due to LINENO-impaired shells.
2115 * tests/torture.at (Configuring subdirectories, Deep Package):
2116 In the --help* tests in read-only trees, make `.' temporarily
2117 writable again for the `stderr' file, and ignore errors due to
2118 the attempt to write configure.lineno.
2119 Report by Patrick Welche.
2121 2007-11-10 Jim Meyering <meyering@redhat.com>
2123 Generate package.m4 in build-dir, not srcdir.
2124 * tests/Makefile.am (package.m4): Adjust target.
2125 Don't redirect directly to $@.
2126 (CLEANFILES): Add package.m4.
2127 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2128 in $(srcdir).
2129 When running $(AUTOTEST), search "." before searching $(srcdir).
2131 Avoid a race condition that would make parallel "distclean" fail.
2132 * tests/Makefile.am (distclean-generic): Replace the default,
2133 automake-provided rule with an identical one, but with an additional
2134 dependency on distclean-local. Simply adding the dependency would
2135 cause automake not to emit the rule at all.
2136 * BUGS: Building with -jN works, now.
2138 Distribute git-version-gen.
2139 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2140 since GNUmakefile is distributed, and requires it for dist* rules.
2142 Remove two more generated files from version control.
2143 * INSTALL: Remove generated file.
2144 * lib/autoscan/autoscan.list: Remove generated file.
2146 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2148 * GNUmakefile (PATH): Remove stray apostrophes; they become
2149 part of PATH, which isn't wanted here.
2151 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2153 New config files output variable `top_build_prefix'.
2154 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2155 `top_build_prefix'.
2156 * doc/autoconf.texi (Preset Output Variables): Document it.
2157 * NEWS: Update.
2158 Report by Bob Friesenhahn.
2160 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2161 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2162 function, to parametrize arithmetic with expr vs. the shell.
2163 Use it where possible.
2164 Suggestion by Benoit Sigoure.
2166 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2168 Adjust the documentation of autotest WRT atlocal.
2169 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2170 when using Automake, to write a rule to produce atlocal, since it's
2171 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2172 distributed, not atconfig.in.
2174 2007-11-04 Eric Blake <ebb9@byu.net>
2176 Update list information.
2177 * README: Mention new autoconf-commit list.
2178 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2180 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2184 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2186 * build-aux/.gitignore: Ignore mkinstalldirs.
2188 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2190 2007-11-03 Jim Meyering <meyering@redhat.com>
2192 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2193 * build-aux/git-version-gen: This syncs from coreutils.
2195 Adjust the build procedure so "make check" works reliably.
2196 * README-hacking: Include an extra step between "make" and
2197 "make check" to ensure that the latter passes.
2199 Use just-built tools, when possible.
2200 * GNUmakefile (PATH): Set and export here, ...
2201 (dummy): ... rather than here.
2203 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2204 and Andreas Schwab <schwab@suse.de>
2206 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2207 exit status bug.
2209 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2211 * configure.ac (AC_PREREQ): Require version 2.60, for
2212 AC_PROG_SED, AC_PROG_GREP.
2214 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2215 and Jim Meyering <meyering@redhat.com>
2216 and Andreas Schwab <schwab@suse.de>
2217 and Eric Blake <ebb9@byu.net>
2219 Document a bug in GNU Bash with compound commands and redirections.
2220 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2221 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2222 workaround.
2224 2007-11-03 Eric Blake <ebb9@byu.net>
2226 Support m4 1.4.5 in testsuite.
2227 * tests/torture.at (Define a newline): Exclude line numbers in
2228 error message.
2229 Reported by Ralf Wildenhues.
2231 2007-11-03 Jim Meyering <meyering@redhat.com>
2233 Remove automake-provided files from version control.

2237 * build-aux/mdate-sh: Remove file.
2238 * build-aux/.gitignore: New file.
2239 Suggestion from Ralf Wildenhues.
2241 2007-11-03 Eric Blake <ebb9@byu.net>
2243 Adjust version comparison to account for git snapshot numbers.
2244 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2245 component separator.
2246 * doc/autoconf.texi (Number processing Macros)
2247 <m4_version_compare>: Document this change.
2248 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2250 2007-10-30 Bruno Haible <bruno@clisp.org>
2252 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2253 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2254 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2255 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2256 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2257 Suggested by Paul Eggert.
2259 2007-10-28 Jim Meyering <meyering@redhat.com>
2261 * README-hacking: Autoconf, Automake, and Perl are required to build.
2262 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2264 2007-10-28 Jim Meyering <meyering@redhat.com>
2266 README-hacking: Recommend running autoreconf -vi.
2267 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2268 so that we use just-built tools when they're available.
2269 Suggestions from Ralf Wildenhues.
2271 2007-10-28 Jim Meyering <meyering@redhat.com>
2273 Make inter-release --version output more useful.
2275 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2276 which indicates that it is built using the 19th change set
2277 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2278 is a prefix of the commit SHA1.
2279 * build-aux/git-version-gen: New file.
2280 * configure.ac: Run it to set the version.
2281 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2282 * Makefile.am (dist-hook): Arrange so that .version appears only
2283 in distribution tarballs, never in a checked-out repository.
2284 * .gitignore: Add .version here, too. Just in case.
2285 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2286 not configure.ac, now that the version number changes automatically.
2288 Ensure that $(VERSION) is up to date for dist-related targets.
2289 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2290 git-version-gen doesn't match $(VERSION), but only for dist targets.
2292 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2294 Fix `Deep Package' failure with a configure script early in PATH
2295 * tests/torture.at (Deep Package): Add `.' early in PATH.

2324 problem reported by Bruno Haible in
2325 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2327 2007-10-22 Eric Blake <ebb9@byu.net>
2329 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2330 preprocessor.
2332 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2334 Don't check for bug in HP-UX 11.00 cpp.
2335 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2336 Use -1ull rather than -1u, since that causes problems with gnulib; see
2337 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2339 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2345 test names.
2347 2007-10-21 Eric Blake <ebb9@byu.net>

2359 unnecessarily. Do not try running `/bin/sh configure' with a
2360 configure script to be found in $PATH, if the shell does not do
2361 this resolution. Fixes test failure on FreeBSD.
2363 Fix config header generation with AIX awk.
2364 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2365 script, use helper array D_is_set, as `" 0"' does not evaluate

2399 (Writing Testsuites): Mention limitations inherited from
2400 m4_expand.
2402 Improve AT_BANNER handling.
2403 * lib/autotest/general.m4 (BANNERS): New named diversion.
2404 (TESTS_END): Diversion no longer used.
2405 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
2406 shell function, which prints only as needed, using an associative
2407 array of banner text from a special diversion.
2408 <PARSE_ARGS_END>: No longer need awk to find banners.
2409 <TESTS>: Banners are no longer processed by main driver loop, so
2410 we no longer need case statement.
2411 (AT_BANNER): Rewrite to populate new diversion.
2412 (AT_SETUP): Each test invokes its own banner. No output is needed
2413 to the TESTS diversion.
2414 * doc/autoconf.texi (Writing Testsuites): Document slight
2415 semantics change.
2416 * tests/autotest.at (AT_BANNERS): Enhance test.

3441 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
3442 choice, since that's what we do with --enable-largefile etc.
3443 Redo indenting and assignments to simplify things a bit, and make
3444 the parens work with Emacs.
3446 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo
3447 in my previous change: AC_C_OPENMP -> AC_OPENMP. Reported by Bruno

3546 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3547 for a.* when searching for executables, as this prevents users

3561 AC_CHECK_TYPE, AC_CHECK_TYPES.
3562 * doc/autoconf.texi (Generic types): C types must be type-names
3563 (the C terminology), not type-ids (the C++ term). C++ types
3564 must not be anonymous.
3565 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3566 for C++; this drops support for anonymous struct and union types,
3567 which were problematic anyway.
3568 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3569 for C++.
3571 2007-04-12 Jim Meyering <jim@meyering.net>

3584 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3585 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3586 with objects too. Document the restrictions on its use.
3587 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3588 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3589 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3590 works but the latter doesn't, then it's a valid type.
3591 This lets people use function types and so forth.
3592 For C++ there doesn't seem to be a simple solution, so leave it alone.
3593 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3594 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3595 AC_CHECK_TYPE; that wasn't documented or necessary.
3597 2007-04-11 Stepan Kasal <kasal@ucw.cz>

3647 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3648 nonstandard grep R.E. escape sequences.
3650 2007-03-17 Jim Meyering <jim@meyering.net>
3652 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3653 (Limitations of Usual Tools): Also list \< and \>, and mention that
3654 HP-UX's grep, like the one from Solaris, does not support that syntax.
3656 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3658 * doc/autoconf.texi (Specifying Names): `--host' does not
3659 change the build type.
3661 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3663 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

3674 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3675 universal binaries. Problem reported by Elias Pipping.

3763 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3765 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3766 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3767 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3768 substitution will still be done by the special code.
3769 Report by Jim Meyering.
3771 * doc/autoconf.texi (File System Conventions): Mention that

3792 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3793 early on the reader side, drop stderr of the input to avoid
3794 `broken pipe' error output; this may happen even with shell
3795 builtin `echo' of some bash versions. Reports by Ian Macdonald
3796 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3798 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3814 and change it a bit to make things clearer.
3815 (Optimization and Wraparound): Clarify whether the compiler
3816 will generate an infinite loop for the example derived from
3817 Autoconf's mktime test.
3818 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3819 Also, clarify unsigned multiplication overflow.
3821 2007-01-04 Eric Blake <ebb9@byu.net>

3835 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3836 feedback. The most important changes document what happens when
3837 you convert an out-of-range value to a signed integer type, and
3838 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3839 a + b.
3841 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3842 rewrite, taking notions from the recent discussion on the gcc and

3845 and follow the many links.
3846 (Integer Overflow Basics, Signed Overflow Examples):
3847 (Optimization and Wraparound, Signed Overflow Advice):
3848 (Signed Integer Division): New sections.
3850 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3852 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3853 preprocessor macro arguments in traced name.
3854 * doc/autoconf.texi (Defining symbols): Document longstanding
3855 support for AC_DEFINE-ing macros with arguments, and document
3856 behavior when the same variable has multiple AC_DEFINEs.
3857 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3858 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3859 macros directly, giving much shorter and simpler code.
3861 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3863 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3864 space before "$ac_configure_args" to prevent a 'config.status
3865 --recheck' failure if ac_configure_args doesn't contain a leading
3866 space. This works around a problem with the XEmacs configure.ac,
3867 which uses the (undocumented) ac_configure_args variable
3868 inconsistently with Autoconf.
3870 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3872 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3873 Include <limits.h>, and use its INT_MAX to rewrite the
3874 j loop so that it does not overflow 'int'. Problem reported by
3875 Ralf Wildenhues in
3876 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3877 Play it safe by shifting left by 1 rather than multiplying by 2,
3878 as GCC is less likely to optimize this away when the value
3879 is signed (when it assumes overflow leads to undefined behavior).
3880 Also, don't assume time_t uses two's complement.
3882 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3884 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3885 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3886 dumps core on it. Report by Tim Rice.
3888 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3890 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3891 --disable-option-checking to --help output even when
3892 AC_PRESERVE_HELP_ORDER is not used.
3893 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3894 --with argument, rather than argument with [-.] replaced by
3895 underscores.
3896 * NEWS: Fix typo in previous change; the news was in the
3897 wrong section.
3899 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3901 * NEWS: Warnings are now generated by default for unknown
3902 --enable-* and --with-* options.
3903 * doc/autoconf.texi (Option Checking): Renamed from
3904 (Configure Option Checking). Tighten up the wording a bit.
3905 (External Software, Package Options): Cross-reference to Option
3906 Checking, and use this to shorten our section.
3907 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3908 "$x" to test "x$foo" != x.
3909 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3910 Don't warn if $enable_option_checking is "no".
3911 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3912 ac_unrecognized_opts to the empty string.
3913 Don't echo the unrecognized opts, as this might mishandle
3914 backslashes or leading -.
3915 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3916 usage next to the other --disable-FEATURE options in the
3917 help string.
3919 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3921 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3922 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3923 Print warning for unrecognized --with and --enable options
3924 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3925 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3926 Disable option checking when subdirs are configured.
3927 (AC_OUTPUT): If warnings are enabled, print warning about
3928 unrecognized --with and --enable options at the end of
3929 the configure output (as well as at the beginning).
3930 * doc/autoconf.texi (Option Checking): New node.
3931 Document new option warning functionality.
3933 2006-12-16 Eric Blake <ebb9@byu.net>
3935 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3936 * NEWS: Start news for current version.
3938 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3940 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3941 Define HAVE_GETMNTENT to 1, not to the empty string.
3942 Problem originally reported by Jochen Friedrich in
3943 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3945 This change prompted by a problem report by Andrey Simonenko in
3946 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3947 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3948 object-like macros only, in the traditional portable character
3949 set.
3950 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3951 Warn about attempts to define things that are not identifiers.
3952 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3953 awful hack that AC_DEFINEd macro names containing parentheses.
3955 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3957 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3958 too drastic, even if Texinfo in theory requires it for info mode.
3960 (config.status Invocation): Renamed back from Recreating a
3961 Configuration).
3962 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3963 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3965 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3967 * NEWS: Version 2.61a.
3969 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3970 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3972 * NEWS: Document changes with echo and printf, and the lack
3973 of limits on the total size of multi-line values of substituted
3974 variables, and the AC_FUNC_FSEEKO fix.
3976 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3978 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3979 Writing configure.ac.
3980 (Autoconf Input Layout): Renamed from configure.ac Layout.
3981 (Recreating a Configuration): Renamed from config.status Invocation.
3982 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3983 (acconfig Header): Renamed from acconfig.h.
3984 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3985 (Writing Testsuites): Renamed from Writing testsuite.at.
3986 (Autom4te Cache): Renamed from autom4te.cache.
3988 * BUGS: Remove mention of VPATH problem, since it's now documented
3989 not to be a bug in the Autoconf build procedure itself, but rather
3990 a problem with the proprietary `make' programs.
3992 * doc/autoconf.texi (Build Directories): Add a cross reference
3993 to VPATH and Make.
3995 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3996 * doc/standards.texi: Sync from gnulib.
3998 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3999 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4000 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4001 generated automatically.
4003 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4005 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4006 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4007 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4009 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4011 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4012 `CEOF$ac_eof' special marker, the awk script cannot contain a
4013 line matching `^CEOF', so this is not needed any more.
4014 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4015 special marker in the test.
4017 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4019 * tests/tools.at (autom4te preselections): Use `find -newer';
4020 remove one of the sleeps.
4022 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4023 more readable, using ...
4024 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4026 * doc/autoconf.texi (autoheader Invocation): Do not double-
4027 quote the parameter of `AH_BOTTOM' in the example.
4029 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4031 * doc/autoconf.texi (Configuration Headers): Remove the
4032 example with multiple input files.
4033 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4034 multiple input files.
4036 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4038 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4039 creating the awk substitution script, handle one input line at a
4040 time, so that the maximum length of a substituted (multi-line)
4041 value is not limited by the size of the sed pattern space.
4042 The trade-off is a slightly repetitive sed script.
4043 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4044 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4045 * tests/torture.at (Substitute a 2000-byte string): Increase the
4046 test with several long lines, they should not be caught by sed
4047 limits any more.
4049 * tests/tools.at (autom4te preselections): New test, to flag
4050 entries missing from autom4te.cfg.
4051 Report by David Byron <dbyron@hheld.com>.
4053 * tests/torture.at (Substitute a 2000-byte string): Actually use
4054 AC_PROG_AWK, so the last change works as intended.
4055 (Substitute and define special characters): Likewise.
4056 (Substitute a newline): Likewise.
4058 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4059 instead of `awk' consistently.
4060 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4061 * tests/torture.at (Torturing config.status): Test both the
4062 result of AC_PROG_AWK and plain awk.
4063 (Substitute a 2000-byte string): Likewise.
4064 (Substitute and define special characters): Likewise.
4065 (Substitute a newline): Likewise.
4067 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4069 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4070 can be assigned to a function pointer. Problem reported by
4071 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4072 part of a patch by Ralf Wildenhues in that same bug report.
4074 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4076 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4077 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4079 2006-12-01 Eric Blake <ebb9@byu.net>
4081 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4082 cross-compiling from cygwin to mingw.
4083 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4084 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4085 to lib/autoconf/c.m4.
4087 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4089 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4090 string for more reliable failure. Wrap the entire test that
4091 causes the broken Solaris printf to dump core, in a subshell,
4092 so the segmentation fault message is reliably suppressed.
4093 Fix shell expansion errors by using /usr/ucb/echo always;
4094 avoid an error on systems without it by another subshell.
4095 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4096 subshell-$as_echo to `as_echo', for better error message.
4098 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4100 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4101 `BASH_SOURCE' contain a newline, set them to empty, as they may
4102 not be unset.
4104 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4106 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4107 years and is too hard to maintain now. The last straw was
4108 reported by Jerker Baeck in
4109 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4110 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4111 * doc/autoconf.texi (Particular Functions): Move
4112 AC_FUNC_SETVBUF_REVERSED from here...
4113 (Obsolete Macros): ... to here. Say that it does nothing now.
4114 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4115 Turn into (almost) a no-op.
4117 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4118 (AC_C_VOLATILE):
4119 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4120 These macros are obsolescent and new applications shouldn't need them.
4121 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4122 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4123 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4124 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4125 (AC_FUNC_VPRINTF): Likewise.
4126 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4127 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4128 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4130 * doc/autoconf.texi (Setting Output Variables): Mention that
4131 @VAR1@VAR2 has unspecified behavior. Problem reported by
4132 Ralf Wildenhues.
4133 * NEWS: Mention this.
4135 * Makefile.am: Put only a single '#' into the copyright notice,
4136 so that it's also present in the output file. Standardize wording
4137 in makefile copyright notices to match GNU coding standards.
4138 * bin/Makefile.am: Likewise.
4139 * doc/Makefile.am: Likewise.
4140 * lib/Makefile.am: Likewise.
4141 * lib/freeze.mk: Likewise.
4142 * lib/autoconf/Makefile.am: Likewise.
4143 * lib/autoscan/Makefile.am: Likewise.
4144 * lib/autotest/Makefile.am: Likewise.
4145 * lib/m4sugar/Makefile.am: Likewise.
4146 * man/Makefile.am: Likewise.
4147 * tests/Makefile.am: Likewise.
4148 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4149 one-line file.
4151 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4153 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4154 in the sed script that mangles the awk script: delete up to the
4155 first exclamation mark only.
4156 * tests/torture.at (Substitute and define special characters):
4157 Test '!' too.
4159 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4161 Rewrite config files generation: avoid quadratic growth in
4162 the number of substituted variables by using awk instead of sed
4163 for the bulk of the substitutions.
4164 * NEWS: Mention this.
4165 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4166 forbidden in the output (and thus input) file.
4167 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4168 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4169 generate just one large awk script for substitutions,
4170 eliminating much of the earlier complexity, while adding some
4171 new complexity. Only expand the substitution templates at
4172 configure time, for smaller configure script size. If
4173 _AC_SUBST_FILES are used, test 'awk' for working getline support
4174 at config.status time. If absent, interpolate through the
4175 shell. The awk script was written with much help
4176 from Paolo Bonzini and Paul Eggert.
4177 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4178 (_AC_SED_FRAG_NUM): Likewise.
4179 (_AC_SUBST_CMDS): Renamed from...
4180 (_AC_SED_CMDS): ...this.
4181 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4182 * tests/torture.at (Substitute a 2000-byte string): Also
4183 substitute a line with 1000 words, and a variable with several
4184 long lines.
4185 (Substitute and define special characters): Test awk special
4186 characters, and put substitution input strings `@foo@' in the
4187 output, to test that no recursion happens; test several other
4188 combinations from Paolo Bonzini.
4190 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4192 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4193 that replaced echo with AS_ECHO where this wasn't necessary.
4194 Problem reportd by Ralf Wildenhues.
4195 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4196 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4197 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4199 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4201 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4203 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4205 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4206 that traditional Awk lacks 3-arg "split". It has it.
4207 Mention that FS must be a single character, and a few other
4208 99-byte limits of traditional Awk.
4209 Mention that if (i in a) doesn't work with traditional Awk.
4211 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4213 * tests/autotest.at (BSx641-newline in command):
4214 (BS-BS-newline in command, BSx640-newline in command):
4215 (Newline-CODE-BS-newline in command):
4216 (Single-quote-BS-newline in command):
4217 (Single-quote-newline-BS-newline in command):
4218 Use printf '%s\n' instead of echo, for portability to hosts
4219 where echo interprets backslashes. This will break on hosts
4220 that lack printf, but for now let's assume all such hosts
4221 are dead (if not, we should get reports of test failures).
4223 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4225 'echo' has some portability problems, when given a first argument
4226 with a leading '-', or when given any argument containing '\'.
4227 Avoid using 'echo' in these cases.
4228 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4229 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4230 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4231 * lib/autotest/general.m4 (AT_INIT): Likewise.
4232 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4233 argument might be unportable.
4234 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4235 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
4236 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
4237 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
4238 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
4239 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
4240 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
4241 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
4242 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
4243 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
4244 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
4245 (AC_PROG_MAKE_SET): Likewise.
4246 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
4247 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
4248 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4249 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
4250 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
4251 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4252 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4253 * bin/autoconf.as: Redo verbose flag implementation, as the old
4254 scheme wouldn't work with AS_ECHO.
4255 * lib/autotest/general.m4 (AT_INIT): Likewise.
4256 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4257 Don't use ECHO_T, since ECHO_N is now reliable.
4258 * lib/autotest/general.m4 (AT_INIT): Likewise.
4259 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4260 rather than using a here-document to put the script into a file.
4261 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4262 use AS_ECHO.
4263 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4264 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4265 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4266 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4267 * lib/autotest/general.m4 (AT_SETUP): Likewise.

4270 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4271 operand, as AS_ECHO requires. Avoid double file name expansion.
4272 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4273 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

4275 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

4288 * NEWS: Likewise.
4290 * tests/autotest.at (Macro with backslash in a test title):
4291 Comment out for now, as this tests neither fails nor passes
4292 reliably. Problem reported by Ralf Wildenhues.
4294 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4296 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

4368 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4370 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4371 benefit of platforms like Solaris+GCC where it is common to have a
4372 non-working g++ installation.
4374 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4375 and Joel E. Denny <jdenny@ces.clemson.edu>

4384 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

4386 Imported from a similar patch to gnulib by Bruno Haible.
4388 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4390 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
4391 * doc/autoconf.texi (C Compiler): Document them.
4392 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
4393 New macros, taken from gnulib.
4395 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

4403 * tests/torture.at (Configuring subdirectories): Do not skip
4404 Automake 1.10 nor future Automake 11.1 (sic).
4406 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4407 and Stepan Kasal <kasal@ucw.cz>
4409 Handle special characters in test case titles correctly.
4410 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all

4414 argument. Extend to check titles printed by ./micro-suite and
4415 ./micro-suite -l and the title in micro-suite.log.
4416 (Backquote in a test title,
4417 Single-quote in a test title,
4418 Double-quote in a test title): Don't expect failure anymore.
4419 (Backslash in a test title): Put a non-whitespace character after the
4420 backslash so that Bourne shells might actually see it as an escape
4421 sequence.
4422 (Brackets in a test title,
4423 Pound in a test title,
4424 Comma in a test title,
4425 Quoted Macro in a test title,
4426 Macro in a test title,
4427 Macro with single-quote in a test title): New tests.

4429 Macro with double-quote in a test title,
4430 Macro with backslash in a test title): New tests expected to fail.
4431 * tests/torture.at (#define header templates): M4-quote this title in
4432 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4433 The visible effect was a stray [] in the testsuite output.
4435 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4437 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4438 `trap ... 0' inside a function, for AIX sh.
4440 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4442 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4443 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4444 5363) simply issues a warning when dividing by zero at compile
4445 time. Problem reported by Elias Pipping.
4447 2006-10-26 Eric Blake <ebb9@byu.net>
4449 * THANKS: Update.
4450 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4451 show effect on macros that expand with commas.
4452 Reported by Joel E. Denny.
4454 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
4455 Also work with M4 1.4.8.

4460 Jim Meyering.
4462 2006-10-25 Stepan Kasal <kasal@ucw.cz>

4469 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

4476 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4478 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4479 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4480 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4481 reported by Nelson H. F. Beebe for Coreutils 6.4.
4483 * tests/tools.at (autoconf --trace: user macros): Remove test
4484 for tracing multiline macros, since m4 1.4.7a uses a different
4485 way to number lines. Problem reported by Ralf Wildenhues.
4487 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4489 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4490 /dev/null since the heuristics for interactive behaviour was
4491 fixed in CVS m4.
4493 * bin/autom4te.in: With --force, always refresh the output
4494 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4496 * bin/autoconf.as: Fix the verbose message at the end.
4498 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4515 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4516 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4518 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4520 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
4522 2006-10-19 Eric Blake <ebb9@byu.net>

4527 m4_mkstemp.

4544 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4546 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4547 looking for special shell characters.
4548 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4549 macro defined by AS_VAR_PUSHDEF before passing it as a
4550 parameter.
4551 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4552 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

4561 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4563 (Imported from Automake.)
4564 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4565 which incorrectly sets the mode of an existing destination
4566 directory. In some cases the unpatched install-sh could do the
4567 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4568 system. We hope this is rare in practice, but it's clearly worth
4569 fixing. Problem reported by Alex Unleashed in
4570 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4571 Also, don't bother to check for -m bugs unless we're using -m;
4572 suggested by Stepan Kasal.
4574 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4576 Import this change from Automake:
4578 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4579 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4580 is enabled by default with gnu and gnits strictness.
4581 Report from Bruno Haible.
4583 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4584 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4585 gnu and gnits modes.
4587 Import this change from Config:
4589 2006-09-20 Ben Elliston <bje@gnu.org>
4590 * build-aux/config.sub (score, score-*): New.
4592 Import this change from Gnulib:
4594 2006-09-16 Karl Berry <karl@gnu.org>
4595 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4596 to avoid sectioning errors.

4600 2006-10-04 Karl Berry <karl@gnu.org>
4601 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4602 (\quoteexpand): rename to \rquoteexpand.
4603 (\codequoteleft): new def, to look for @set codequotebacktick.
4604 (\lquoteexpand, \quoteexpand): new defs.
4605 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4606 (\code): must use new \...Char values, since now ` is active.
4608 2006-08-26 Karl Berry <karl@gnu.org>
4609 * build-aux/texinfo.tex (\textdegree): New command.
4611 2006-08-12 Karl Berry <karl@gnu.org>
4612 * build-aux/texinfo.tex (error \box0): smaller font.
4614 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4616 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4618 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4620 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4621 added to the template can get mangled.
4623 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4625 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4626 include the default headers, and redefine obstack_chunk_alloc
4627 and obstack_chunk_free. Fixes false failure with glibc.
4629 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4631 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4632 for backward compatibility with Libtool 1.5.22. Problem reported
4633 by Ralf Wildenhues.
4635 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4637 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4638 AC_PROG_CC.
4639 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4641 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4643 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4644 the NonStop platform.

4646 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4648 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4649 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4650 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4651 Use a better substitute, by inspecting the output of "ls"
4652 rather than just using ":".
4653 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4654 rather than AS_EXECUTABLE_P, since we needn't worry about
4655 non-regular files here.
4657 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4658 due to configuration hassles with this. See Tonya Underwood's report
4659 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4660 * doc/autoconf.texi (Special Shell Variables): Likewise.
4662 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4663 Stepan Kasal <kasal@ucw.cz>
4665 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4666 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4668 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4670 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4671 initialization which is not inherited through the environment
4672 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4673 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4675 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4677 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4678 problems with mkdir -p -m.
4680 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4682 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4683 comment about ac_cpp_err; it was incorrect, and anyway
4684 ac_cpp_err is being removed below.
4685 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4686 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4687 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4688 nobody uses it.
4689 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4690 with werror_flag and conftest.err and so forth. This is more
4691 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4692 and anyway the user shouldn't normally want to see this gorp logged.
4693 Problem reported by Ralf Wildenhues.
4694 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4695 empty, not 'no', since the rest of the code uses 'test -z'.
4697 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4699 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4700 Use a single call to AC_DO_TOKENS rather than multiple, for
4701 efficiency.
4702 (_AC_LINK_IFELSE): Test that resulting file is executable.
4703 Problem reported by mwoehlke in
4704 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4706 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4707 than creating a file to use with test -x; this is much faster.
4709 2006-10-02 Bruno Haible <bruno@clisp.org>
4711 * lib/autom4te.in (Automake-preselections): Add
4712 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4714 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4716 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4717 standard error, `experr' should be used, not `expout'.
4719 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4721 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4722 fseeko testing program twice; just use the earlier result.
4723 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4724 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4725 still doesn't let the program compile.
4726 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4727 failed.
4729 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4730 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4731 include it, without including anything else.
4732 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4733 expressions.

4859 to catch glibc bug 2821
4860 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4862 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4863 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4864 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4865 assume C89.

4887 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over

4963 deal with LEXLIB.
4964 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4965 didn't work if some values were cached but not others. Test for
4966 broken lex libraries like native ia64-hp-hpux11.22; see
4967 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4968 work around the problem by preferring an empty LEXLIB to -lfl or
4969 -ll. Let the user set LEXLIB='' to indicate no library needed.
4971 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4972 * README: Likewise.

5170 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5171 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5173 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5175 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5176 after -R regardless of host. Patrick Welche reports that this
5177 fixes things on NetBSD 3.99.
5179 * NEWS: Recommend M4 1.4.5.
5180 * README: Likewise.
5181 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
5182 * tests/tools.at (autom4te cache): Update wording of diagnostic
5183 to match M4 1.4.5.
5185 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5187 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5188 under AC_C_VOLATILE.
5189 (Volatile Objects): Be a little less skeptical about what
5190 "volatile" means. Derived from thoughts by Ben Pfaff in
5191 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5193 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5195 * doc/autoconf.texi: Fix some typos.
5197 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5199 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5200 more globally, since the 2006-06-30 patch didn't suffice. Problem
5201 reported by Keith Marshall. Also, don't bother with builddir2,
5202 since it shouldn't be needed any more.
5204 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5206 * doc/autoconf.texi (Generic compiler characteristics):
5207 Document AC_COMPUTE_INT. Fix wrong statements on Default
5208 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5210 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
5211 (_AC_COMPUTE_INT): Add obsoletion warnings.
5212 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
5213 AC_COMPUTE_INT.
5215 * NEWS: Document change.
5217 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5219 * doc/autoconf.texi (Volatile Objects): New section.
5221 * NEWS: Document previous change.
5223 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5225 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5226 Require that long long int be at least 64 bits wide. C99 requires
5227 this and enough programs depend on it so we should check for it.
5228 Bruno Haible reports in
5229 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5230 that long long int is 32 bits wide with some nonstandard compilers.
5231 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5233 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5235 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5236 to a nonexistent file, so that we don't have to worry about
5237 a local site configuration that doesn't use /usr/local.
5238 Problem reported by Keith Marshall in
5239 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5241 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5243 * doc/autoconf.texi: Be more consistent about using @acronym with
5244 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5245 quite right (it talked about "OSF/Tru64", even though the
5246 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5247 and it even mentioned "OSF 4"!) and at this point there's little
5248 reason to talk about OSF any more, since it died in 1994.
5249 (Specific Compiler Characteristics): Simplify example of
5250 negative-size array.
5251 (File Descriptors): Reorder to make the text flow better.
5252 Remove joke about "appreciate the various levels"; I didn't get it.
5253 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5254 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5255 (File Descriptors, Limitations of Usual Tools):
5256 Tone down the advice against renaming or removing open files.
5257 (Limitations of Usual Tools): Add a new section, on 'rm'.
5259 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5261 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5262 -lXt in LIBS, idea from Karsten Hopp; this was due since
5263 this change:
5265 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5266 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5267 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5268 (which belong to Xt, not X itself). See Debian bug 327655.
5270 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5272 * configure.ac (AC_INIT): Bump to 2.60a.
5273 * NEWS: Update.
5275 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5277 Version 2.60.
5279 * configure.ac, NEWS: Update.
5281 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5283 * config/texinfo.tex: Sync from upstream.
5285 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5286 quadrigraph correctly in traces.
5288 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5289 Fix typos.
5291 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5292 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5293 not defined.
5294 * doc/autoconf.texi (Changed Directory Variables): New node,
5295 to document the whole `datarootdir' business a bit better.
5296 * NEWS: Update.
5297 * tests/torture.at (datarootdir workaround): Extend test.
5298 Prompted by report by Alexandre Julliard.
5300 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5302 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5303 when using default mode of IBM C 6 for AIX. Problem and two-line
5304 fix reported by Larry Jones.
5306 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5308 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5309 about literal '${datarootdir}' if a definition is found in the
5310 output file.
5312 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5314 * NEWS: Use "M4" rather than "m4" when appropriate.
5315 Problem reported by Eric Blake.
5316 * doc/autoconf.texi: Likewise.
5317 Use @acronym around BSD, GCC, and GNU when appropriate.
5318 (Why GNU M4): Renamed from "Why GNU m4".
5319 (Redefined M4 Macros): Mention that Posix
5320 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5321 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5322 to int.
5324 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5326 * bin/autom4te.in (handle_output): Do not forbid the empty
5327 pattern.
5328 * tests/tools.at (autoconf: the empty token): New test.
5330 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5332 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5333 calls, so that we do not care whether they are LIFO or FIFO;
5334 in the m4_wrap, do not check which diversion is the topmost
5335 one, just check that the stack is balanced at the end.
5336 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5337 base diversion forever--pop the previous diversion before
5338 opening the new one; consequently, remove the m4_wrap call.
5339 * lib/autotest/general.m4 (AT_INIT): Likewise.
5340 * tests/m4sugar.at: Do not use
5341 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5343 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5344 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5346 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5347 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5348 Rework example of m4wrap token-pasting trouble so that it doesn't
5349 care whether it's LIFO or FIFO.
5350 Fix some "contrary to"s that are awkward in English.
5352 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5354 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5355 to `yes' instead of `int$1_t' if the type is found, for more
5356 consistent configure output (where $1 is the number of bits).
5357 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5358 Suggested by Bruno Haible.
5360 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5361 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5362 with system headers. Report by Bruno Haible.
5364 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5366 * config/config.guess, config/config.sub: Sync from upstream.
5368 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5369 in order to avoid picking up an older installed frozen m4sh.m4f.
5370 Besides an outdated shell startup, this could have been created
5371 by an earlier M4 version with incompatible frozen file format.
5373 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5375 * README: Recommend m4 1.4.4 instead of 1.4.3..
5376 * doc/autoconf.texi: Likewise.
5377 (Special Chars in Names): Say that $(.FOO) is portable, as
5378 suggested by Stepan Kasal.
5379 (Installation Directory Variables, Build Directories):
5380 (Automatic Remaking, Subdirectories, Fortran Compiler):
5381 (Making testsuite Scripts, Defining Directories):
5382 Quote variable usages better.
5383 (Making testsuite Scripts): Add clean-local rule to makefile
5384 snippet, by Eric Blake.
5385 (Installation Directory Variables): Fix table item font.
5386 Reword slightly to clarify. Generalize advice about
5387 not using special characters to include all file-related
5388 vars, not just VPATH.
5389 (Special Chars in Variables): Warn about special characters in
5390 $(srcdir) too.
5391 (Assignments): Clarify default-value example as suggested by
5392 Ralf Wildenhues in
5393 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5394 (Special Shell Variables): Note leading ./ or ../, as suggested
5395 by Eric Blake.
5396 (Limitations of Builtins): Under cd, warn about CDPATH.
5397 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5398 Ralf Wildenhues.
5400 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5402 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5403 `@var', for texi2html.
5404 (Systemology): Some more word wrapping, for DVI output.
5405 (autom4te Invocation): The short option for `--melt' is `-M',
5406 not `-m'.
5408 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5410 * doc/autoconf.texi: More formatting and English tweaks,
5411 many suggested by Ralf Wildenhues.
5412 Reword to avoid "@code{...}'s" and the like, since it's ugly
5413 with Emacs info mode. discontents -> woes.
5414 Put a few "will"s back. time stamp -> timestamp.
5415 side-effect -> side effect.
5417 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5419 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5420 Warn about $@ not persisting. Problem reported by Julien Danjou in
5421 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5422 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5423 Mention other special chars, too.
5425 2006-06-14 Eric Blake <ebb9@byu.net>
5427 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5429 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5431 * doc/autoconf.texi: Some systematic minor improvements, as
5432 follows. Use "makefile" when talking about makefiles
5433 generally (which might be named "makefile" or "Makefile" or even
5434 "foo.mk"), "Makefile" when talking about a specific makefile
5435 called "Makefile". This unclutters the text from weird quotes
5436 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5437 values" rather than "@var{foo}s" and similar constructs containing
5438 "}s". Use "Make rules" rather than "Makefile rules". Minor
5439 English-language improvements. Change the prefix "sub-" to "sub"
5440 and "re-" to "re".
5441 Put blank lines around examples more consistently.
5442 Avoid "rather" and "very" as intensifiers.
5443 Avoid "will" as an auxiliary.
5444 (Limitations of Make): Split this node into....
5445 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5446 (Leading _ in Macro Names, Backslash-Newline-Newline):
5447 (Backslash-Newline Comments, Long Lines in Makefiles):
5448 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5449 (obj/ and Make, make -k Status, VPATH and Make):
5450 (VPATH and Double-colon, $< in Explicit Rules):
5451 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5452 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5453 New nodes, resulting from splitup of Limitations of Make.
5454 All cross-references changed. Raise the top node from
5455 a section to a chapter, and all subnodes accordingly.
5456 Redo the introductory wording to match the new organization.
5457 (Installation Directory Variables): Use an example that is
5458 closer to what Autoconf actually does. Mention that VPATH's
5459 value should not contain metacharacters or white space.
5460 (Fortran Compiler): Fix a VPATH bug in an example.
5461 (Leading _ in Macro Names): Mention that this problem is no longer
5462 of practical concern.
5463 (VPATH and Make): Reword the advice to make it clearer
5464 that Autoconf and Automake support VPATH in non-GNU make, but
5465 many packages have bugs in this area.
5466 ($< in Explicit Rules): Refer to Build Directories rather
5467 than using a (non-VPATH-safe) example.
5468 (Automatic Rule Rewriting): Mention the sort of disaster that
5469 can ensue with Solaris-style rule rewriting with VPATH.
5471 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5473 * doc/install.texi (Compilers and Options): Weaken the
5474 suggestion to use GNU make for VPATH builds.
5476 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5477 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5479 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5480 in regular expression.
5482 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5484 * doc/autoconf.texi (Installation Directory Variables):
5485 Drop extra @samp from `@table @samp' item.
5486 (Limitations of Usual Tools): Comment fix.
5487 Do not nest @samp just to point to other table items.
5488 (Writing testsuite.at) <AT_CHECK>: The second argument to
5489 `@dvar' is already @samp'ed.
5490 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5491 do not use @var in the second argument.
5493 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5495 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5496 $as_shell.exe too. Problem reported by Andreas Buening in
5497 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5499 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5501 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5502 `unused variable' compiler warning, for `-Wall -Werror'.
5503 Reported by Jaap Haitsma in
5504 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5506 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5508 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5509 case the compiler dumps core. Problem reported for
5510 OpenServer 5.0.7 by Tim Rice in
5511 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5512 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5513 Likewise.
5515 2006-06-06 Tim Rice <tim@multitalents.net>.
5517 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5518 "ERROR" only shows up in "make check" output if there is an
5519 error.
5521 2006-06-06 Eric Blake <ebb9@byu.net>
5523 * tests/tools.at (automatically allowed tokens): Fix typo.
5525 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5527 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5529 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5530 typically overflows on x86 CPUs, even though the C standard
5531 requires otherwise.
5533 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5535 * configure.ac (AC_INIT): Bump to 2.59e.
5536 * NEWS: Update.
5538 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5540 Version 2.59d.
5542 * config/texinfo.tex: Sync from upstream.
5544 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5545 seen, invoke libtoolize with `--ltdl' argument.
5546 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5547 * NEWS: Update.
5548 Suggested by Eric Blake.
5550 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5552 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5553 reported by Ralf Wildenhues.
5554 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5556 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5569 * tests/base.at: Check AC_REQUIRE's error message.
5570 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5571 to...
5572 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5573 AT_CHECK_M4.
5574 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5575 `expout' as the last parameter.
5576 * tests/tools.at: Adapt to the above change.
5578 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5580 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5581 information about race-free implementations of mkdir.
5583 2006-06-04 Eric Blake <ebb9@byu.net>
5585 * bin/autoreconf.in (help): Document M4 environment variable.
5586 * bin/autoconf.as (Usage): Likewise.
5587 * bin/autom4te.in (help): Likewise.
5588 * doc/autoconf.texi (autom4te Invocation): Likewise.
5590 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5592 * NEWS: GNU make now recommended for VPATH builds.
5593 Mention that some macros are now documented to be obsolescent.
5594 * doc/autoconf.texi:
5595 Prefer "current" to "modern" to describe
5596 currently-used (albeit perhaps old-fashioned) hosts.
5597 Mention which ancient features no longer need to be worried about.
5598 setgid -> set-group-ID
5599 setuid -> set-user-ID (these are the Posix terms)
5600 Fix some misuses of "only".
5601 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5602 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5603 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5604 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5605 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5606 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5607 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5608 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5609 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5610 Mention that these macros are obsolescent.
5611 (Installation Directory Variables): shall -> should
5612 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5613 Mention that it's now safe to use 3 and 4.
5614 (Limitations of Usual Tools): cp -r is now specified by Posix.
5615 Omit longwinded and obsolescent discussion of cp -f.
5616 Modernize discussion of expr, ls.
5617 (Limitations of Make): Modernize discussion of VPATH builds.
5618 Mention $? as a workaround in some cases.
5619 * doc/install.texi (Basic Installation):
5620 Mention "./configure; make; make install" first. Be more
5621 specific about why this file is generic. Remove unnecessary
5622 parens. Remove misleading "only". Remove obsolete advice
5623 about csh. Don't say "configure" takes awhile; say it
5624 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5625 and CC=c99 rather than CC=c89, as these are blessed by current
5626 Posix. Recommend GNU make if doing a VPATH build.
5628 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5630 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5631 examples involving shell prompts.
5633 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5634 and Paul Eggert <eggert@cs.ucla.edu>
5636 * doc/autoconf.texi (Here-Documents): Add details about the
5637 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5638 use "here-documents" instead of "here documents".
5640 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5642 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5644 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5646 * doc/autoconf.texi (File System Conventions): Warn about ":"
5647 anywhere in directory names.
5649 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5651 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5652 about quoting the case statement, just in case.
5653 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5654 was fixed in ksh93g; reported by Ralf Wildenhues.
5656 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5658 * doc/autoconf.texi (System Services): Do not document
5659 overriding EXEEXT via ac_cv_exeext=ext.
5660 (Particular Programs) <AC_PROG_MKDIR_P>:
5661 Document that ${MKDIR_P} understands --.
5662 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5663 comment.
5665 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5667 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5668 argument with leading hyphen. Problem reported by Paul Eggert.
5670 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5672 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5673 about quoting ac_try: quote all of it, if any of it seems suspicious.
5674 This means we don't have to worry about ${ or sed any more.
5675 Also, double-quote the case statement, to work around misuses via
5676 underquoting as reported by Ralf Wildenhues in
5677 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5678 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5679 undocumented and dangerous macro.
5680 Problem reported by Ralf Wildenhues in
5681 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5683 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5685 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5686 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5687 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5689 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5691 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5692 since evidently some packages rely on the old, broken behavior.
5693 Problem reported by Ralf Wildenhues in
5694 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5695 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5696 pre-2006-05-26 definitions, but leave in the comments that
5697 these macros are dangerous and should not be used.
5698 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5699 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5700 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5701 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5702 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5704 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5706 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5707 the use of 'tr', since this is our only use of 'tr'.
5709 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5710 and Paul Eggert <eggert@cs.ucla.edu>
5712 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5713 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5715 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5717 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5718 the output file in the `${datarootdir}' test.
5720 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5721 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5723 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5724 mention of `datarootdir' in the input file(s), but literal
5725 `${datarootdir}' in the output file, and we haven't warned yet,
5726 then warn as well: the user may have (erroneously) used
5727 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5728 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5729 * tests/torture.at (datarootdir workaround): Extend this test.
5730 * NEWS: Update.
5732 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5733 and Paul Eggert <eggert@cs.ucla.edu>
5735 * doc/autoconf.texi (autoheader Invocation): The first argument to
5736 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5737 alternatives and clear up the language a bit.
5739 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5741 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5742 ac_config_guess, ac_config_sub, ac_configure.
5743 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5744 Fix typo that prevented an unnecessary space from being removed.
5745 Problems reported by Ralf Wildenhues in:
5746 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5748 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5750 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5751 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5752 Don't use the term "thread-safe" to talk about mkdir race
5753 conditions, since the problem is more a process than a thread
5754 issue. Problem reported by Stepan Kasal in:
5755 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5756 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5757 the test for 'install' more closely. Look at MKDIR_P first.
5758 Look in the PATH, and at /opt/sfw/bin.
5759 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5760 Don't bother to try mkdir -p, since we already check mkdir --version;
5761 just look at the version number. (There's no easy way to check
5762 for race-free implementations.)
5763 * tests/tools.at (autoconf: subdirectories): Adjust to above
5764 changes, since MKDIR_P now might end in "/mkdir -p".
5766 * doc/autoconf.texi (autoheader Invocation): Mention that the
5767 first arg of AC_DEFINE_UNQUOTED must be a literal.
5768 Problem reported by Ben Pfaff in
5769 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5771 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5772 * doc/autoconf.texi (Special Chars in Variables): New section.
5773 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5774 (Installation Directory Variables): Quote $(datadir) better.
5775 (Limitations of Builtins): Describe some of eval's trickiness.
5777 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5778 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5779 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5780 in front of every arg, not just trailing args. Quote apostrophes.
5781 (_AC_EVAL_ECHO): New macro.
5782 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5783 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5784 removed.
5785 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5786 exposed by quoting of eval argument. Put the command on line line
5787 so it logs better.
5788 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5789 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5790 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5791 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5792 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5793 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5794 Use eval more safely.
5795 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5796 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5797 to be replaced.
5798 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5799 lines, exposed by quoting of eval argument.
5801 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5802 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5804 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5805 initialization of `ac_cv_exeext', do not override it if it was
5806 already set, unless it was set to `no', for compatibility with
5807 Autoconf-2.13, and comment this.
5808 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5809 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5810 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5811 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5812 Document that this test may be overridden by setting
5813 `ac_cv_exeext'.
5815 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5817 Revert these two patches:
5819 2006-04-06 Eric Blake <ebb9@byu.net>
5820 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5821 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5822 2006-04-01.
5824 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5825 Clean up _AC_COMPILER_EXEEXT* macros.
5826 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5827 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5828 ac_file to the name of the default output file and call
5829 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5830 initial `rm' of the candidate files...
5831 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5832 the same list in subsequent `rm' calls, and for the temporary
5833 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5834 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5835 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5836 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5837 no longer needed) by libtool. Make it a cache check.
5838 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5839 copied here by mistake.
5840 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5841 _AC_COMPILER_EXEEXT.
5842 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5843 _AC_COMPILER_OBJEXT directly.
5844 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5846 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5848 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5849 Fix description of how the buggy `sed' works.
5851 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5853 Sync from Automake:
5855 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5856 ENOLCK. Only mention `make -j' when applicable. Only raise
5857 fatal errors when `make -j' is involved. Improve error message.
5859 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5861 * doc/autoconf.texi (Here-Documents): We now know more about
5862 the variable expansion in here documents bug.
5863 Thanks to Tim Rice and Stepan Kasal.
5865 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5866 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5868 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5870 * tests/autotest.at (Multiline command from M4 expansion):
5871 No failure to be expected if the shell quotes newlines in
5872 commands in the `set -x' output. Report by Tim Rice.
5873 * THANKS: Update.
5875 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5877 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5878 expansion in the here-documents used by config.status, as that
5879 runs afoul of the Korn shell version M-12/28/93d bug described in
5880 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5881 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5882 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5884 2006-05-23 Jim Meyering <jim@meyering.net>
5886 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5887 Fix typo introduced with 2006-04-02 change. It reversed the sense
5888 of the test.
5890 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5892 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5893 ac_dB slightly, to save bytes in the script.
5894 Max out at 50 lines, rather than 96; this is more likely
5895 (though not guaranteed) to avoid obscure 'sed' failures.
5897 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5899 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5900 `tr -d -' as bad option argument. Work around this by deleting
5901 an unrelated character.
5902 Report by Tim Rice <tim@multitalents.net>.
5904 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5905 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5906 Stepan Kasal <kasal@ucw.cz>
5908 * doc/autoconf.texi (Particular Programs): Do not promise that
5909 we always prefer the GNU version of the program, and that we
5910 search according to PATH; both rules can have exceptions.
5911 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5912 AC_PROG_SED. Move descriptions of limitations
5913 to the Limitations of Usual Tools section.
5914 (Limitations of Usual Tools) <sed>: Mention script length
5915 limitations with Solaris /usr/ucb/sed.
5916 <grep>: Fix wording for empty alternative. Mention that -c and
5917 -l should not be combined, and that -E and -F should not be
5918 combined.
5920 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5921 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5923 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5924 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5926 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5928 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5929 AC_DEFINE is now passed to m4_pattern_allow.
5930 * NEWS: Mention that; likewise for AC_SUBST.
5931 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5932 the parameter to m4_pattern_allow.
5933 * tests/tools.at: Add a check for that.
5935 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5937 * lib/autoconf/status.m4: Fix typos.
5939 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5941 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5942 only the files that this macro generates.
5944 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5946 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5947 the HP-UX sed limitation of 99 commands, labels do not count.
5948 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5949 in the comment.
5950 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5952 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5954 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5955 Import the following fix from coreutils:
5957 2006-01-13 Jim Meyering <jim@meyering.net>
5959 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5960 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5961 not double-quote uses of that variable, to accommodate the rare
5962 case in which getmntent is available in none of the libraries
5963 checked. This happens at least on FreeBSD 5.0.
5965 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5967 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5968 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5969 some other programs unwisely rely on these undocumented vars.
5970 But put in warning comments about them.
5971 Problem reported by Ralf Wildenhues in
5972 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5973 * NEWS: Document that these variables are intended to go away.
5975 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5977 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5978 and set the language to C++ (analogous to the equivalent Fortran
5979 tests).
5981 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5982 * doc/autoconf.texi (C++ Compiler): Document it.
5983 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5984 * NEWS: Update.
5986 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5988 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5989 that caused config.status to generate 100-command sed scripts; the
5990 portable limit is 99.
5992 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5994 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5995 variable `ac_d' instead of `d' to avoid infringing namespace.
5996 Report by Ralf Menzel.
5998 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6000 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6001 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6002 * tests/tools.at (autoconf: subdirectories): New test, taken from
6003 the corresponding problem report by Ralf Wildenhues in:
6004 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6006 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6007 Quote some uses of shell variables if they might suffer unexpected
6008 globbing. This doesn't fix all instances of quoting problems that
6009 I found, just the easy ones that look safe.
6010 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6011 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6012 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6013 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6014 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6015 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6016 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6017 Likewise.
6018 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6019 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6021 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6023 * bin/autoreconf.in ($help): Reword according to the manual.
6024 Suggested by Olly Betts.
6026 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6027 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6029 * bin/autoreconf.in: Pass the directory argument to
6030 `require_configure_ac'. Fix comment.
6031 * tests/torture.at (Configuring subdirectories): Expose this.
6032 Reported by Olly Betts.
6034 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6036 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6037 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6038 Automake as follows:
6040 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6041 `$configure_in' instead of `configure.in', to preserve
6042 directory component.
6044 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6046 * config/config.guess, config/config.sub, config/texinfo.tex,
6047 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6049 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6051 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6052 test for C99 conformance; (bool) 0.5 is an integer constant
6053 expression, but (bool) -0.5 is not. Problem reported by Fedor
6054 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6056 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6058 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6059 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6060 Warn about obsolete install-sh files. Remove stray sentence
6061 fragment and fix cross reference.
6062 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6063 install -d; this undoes the 2006-05-10 change.
6064 (MKDIR_P): Mark with AN_MAKEVAR.
6065 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6066 that we don't require $INSTALL to be thread-safe. Move comments
6067 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6068 of AC_PROG_INSTALL. Output a message saying that we're checking
6069 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6070 MKDIR_P instead of AC_SUBST.
6071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6072 Special magic for MKDIR_P, too.
6073 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6074 a dnl.
6075 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6077 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6079 Sync from Automake, as follows:
6081 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6082 * config/install-sh: Initialize IFS, so field splitting isn't
6083 turned off later.
6084 * config/mkinstalldirs: Likewise.
6085 * config/missing: Remove superfluous quotes. Replace all uses of
6086 `[' by `test', for consistency, and for..
6087 * config/missing (sed_minuso, sed_output): New variables.
6088 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6089 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6090 Fixes `missing' to detect `--output' for help2man. Fixes
6091 PR automake/483. Report by Dennis J. Linse.
6092 (autom4te): Document in `missing --help'.
6094 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6096 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6097 * config/install-sh: Don't use 'path' to talk about file names,
6098 as per GNU coding standards. Close a race condition reported by Ralf
6099 Wildenhues and Stepan Kasal. There is still a race condition
6100 on hosts that predate Posix 1003.1-1992, but we can't help this.
6101 Don't mishandle weird characters like space on pre-Posix hosts.
6102 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6103 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6104 AC_PROG_MKDIR_P from AS_MKDIR_P.
6105 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6106 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6107 earlier editions are not (including Automake 1.8.3).
6108 Do not suggest mkinstalldirs for thread-safety.
6109 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6110 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6111 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6112 presence of special characters and race conditions.
6113 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6114 in Autoconf's name space.
6116 2006-05-10 Bruno Haible <bruno@clisp.org>
6117 and Paul Eggert <eggert@cs.ucla.edu>
6119 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6120 from Automake with minor changes.
6121 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6123 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6125 * config/install-sh: Update to Automake CVS version, as follows:
6126 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6127 * lib/install-sh: Simplify the expr implementation of dirname.
6128 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6129 * lib/install-sh: Handle --, and diagnose unknown options.
6131 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6133 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6134 `./autom4te' to create `./testsuite', since the `all' target
6135 will ensure its presence, but `installcheck' should not create
6136 the uninstalled wrappers.
6138 * tests/torture.at (Unusual Automake input files): Skip if we
6139 detect automake < 1.8.
6141 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6143 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6144 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6145 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6146 * NEWS: Update.
6148 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6150 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6151 munge (multiple) white space and other oddities.
6152 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6153 single quotes in variable assignment.
6154 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6155 and similar failures by adding multiple spaces, tabs, and other
6156 special characters.
6157 Report and different test suggested by Francesco Romani
6158 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6160 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6161 single quotes, we only need to search for single quotes; this
6162 both simplifies the search pattern, and makes us less
6163 susceptible to `echo' variations for arguments not containing
6164 single quotes.
6165 (_AC_ARG_VAR_VALIDATE): Likewise.
6167 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6169 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6170 `$*' and IFS concatenation issue with traditional shells and
6171 bash-2.04. Report by Seanster@Seanster.com.
6173 2006-05-03 Bruno Haible <bruno@clisp.org>
6175 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6176 precisely which Mac OS X versions have the od problem.
6178 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6180 * doc/autoconf.texi: Use @option systematically.
6182 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6183 and Bruno Haible <bruno@clisp.org>
6185 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6186 about 'od'.
6187 (Integer Overflow): Mention the special case of integer division
6188 overflow.
6190 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6192 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6193 traditional shells like the Solaris one that do not use the
6194 first IFS character for assembling `$*'.
6195 Prompted by a related report from autoconf_bug@nro.ca.
6197 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6198 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6200 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6201 Mention more problems with the -e option.
6203 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6205 * NEWS: Typo.
6206 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6208 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6209 in URLs to improve DVI formatted output (requires texinfo 4.6).
6210 (System Services, Systemology, Shellology): Likewise.
6211 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6212 output.
6214 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6215 continuous text.
6216 (Runtime): Fix macro argument names to match description:
6217 `action-if-found' -> `action-if-true' and similarly.
6218 (Obsolete Macros): Likewise.
6219 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6220 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6221 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6223 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6225 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6227 * ChangeLog: Typo.
6228 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6229 DVI output.
6231 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6233 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6234 /bin/sh set unsorted output.
6235 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
6236 * tests/local.at: Likewise.
6238 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
6240 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6241 (Integer Overflow, Null Pointers, Buffer Overruns):
6242 (Floating Point Portability, Exiting Portably): New sections.
6243 (Writing Test Programs): Fix some langauge. Recommend exiting
6244 with status 1, not merely nonzero. Clarify exit declaration.
6245 (Run Time): Move C exit status stuff to new Exiting Portably section.
6246 (Systemology): Mention Posix and levenez. Update v7 reference.
6247 (Portable Shell): Mention the Posix shell.
6249 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6251 * bin/autoconf.as (me): Replace by as_me.
6253 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6255 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6256 since as_me isn't set yet.
6258 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6260 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6261 a few minor bugs in this area.
6263 * doc/autoconf.texi (Programming in M4sh): Comment out the
6264 documentation of AS_BASENAME, for now.
6265 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6266 (Limitations of Builtins) <basename>: Do not refer to
6267 AS_BASENAME.
6268 * bin/autoconf.as (me): Don't use AS_BASENAME.
6269 (dir): Remove the unused variable.
6270 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6271 AS_DETECT_REQUIRED. All uses changed.
6272 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6273 All uses changed.
6274 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6275 (AS_BASENAME): Use "basename --" to protect against leading "-".
6276 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6277 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6278 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6279 (_AS_DIRNAME_PREPARE): Likewise.
6280 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6281 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6282 (AS_DIRNAME): Use "dirname --".
6284 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6286 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6287 of "run time" and "run-time" changed to "runtime", for consistency.
6288 * lib/autoconf/fortran.m4: Likewise (in comment).
6289 * lib/autoconf/functions.m4: Likewise.
6290 * lib/autoconf/general.m4: Likewise.
6291 * lib/autoconf/headers.m4: Likewise.
6293 * doc/autoconf.texi (Run Time): Document the exit status situation
6294 with more accuracy and detail.
6296 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6298 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6299 Archive is not officially `GNU' any more. Update URL.
6300 (Defining Directories): Likewise
6301 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6303 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6305 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6306 newline from the `trap' code to finish `config.log'; the NetBSD
6307 /bin/sh resets the exit status after an empty command, as
6308 documented in doc/autoconf.texi.
6309 Reported by Dalibor Topic <robilad@kaffe.org>.
6311 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6313 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6314 Suggested by Bruno Haible.
6316 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6318 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6319 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6320 Instead, just list the shells that we know work.
6321 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6322 changed. Be more cautious about the _cv_ variable.
6323 * tests/tools.at (Syntax of the shell scripts): Check the
6324 _cv_ variable once, at first, to avoid an internal autoconf error
6325 when sh -n does not work.
6327 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6329 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6331 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6333 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6334 use ">&-" since we're only 99.999% sure that this is portable,
6335 and since the MinGW bug is fixed in a different way.
6336 * lib/autotest/general.m4 (AT_INIT): Likewise.
6338 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6340 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6341 before opening config.log, to avoid hitting a bug on MinGW.
6343 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6345 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6346 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6347 This works around a MinGW bug reported by Eric Paire.
6348 Make sure that all writes to the log file append to it,
6349 rather than possibly losing data.
6350 * lib/autotest/general.m4 (AT_INIT): Likewise.
6352 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6354 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6355 description.
6357 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6359 * NEWS: Update.
6361 * configure.ac (AC_INIT): Bump to 2.59d.
6363 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6365 Version 2.59c.
6367 * Makefile.maint (news-date-check): Do not require a leading `*'
6368 before the release date in NEWS.
6370 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6371 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6374 the instantiated file do not contain the string 'datarootdir'
6375 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6376 @mandir@, replace the reference '${datarootdir}' by the value.
6377 * tests/torture.at (datarootdir workaround): New test.
6378 * NEWS: Advertise this temporary fixup.
6379 Based on a patch by Bruno Haible, reported and analyzed by
6380 Paul Eggert and Noah Misch.
6382 2006-04-12 Eric Blake <ebb9@byu.net>
6384 * tests/autotest.at (Debugging a failed test): Fix comment.
6386 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6388 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6389 all the changes since 2006-04-07.
6391 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6393 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6394 succeeded, but `ln -s file dir' failed, take care to remove the
6395 leftover target before the next test, to prevent its spurious
6396 failure; also make sure `ln file dir' works before selecting it.
6397 Thanks to Keith Marshall for pointing this out.
6398 * THANKS: Update.
6400 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6401 assignments in `at_debug_args', so that we put them correctly
6402 in the `run' script.
6403 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6404 Reported by Eric Blake.
6406 2006-04-11 Eric Blake <ebb9@byu.net>
6408 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6409 top-level tests after micro-suite has been run. Used in...
6410 (Debugging a successful test, Debugging script and environment),
6411 (Debugging a failed test): ...these new tests. The first of these
6412 is fixed by...
6413 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6414 macro, split out from...
6415 (AT_INIT): ...here, so that using -d also generates a run script.
6416 Document that -d inhibits top-level logging.
6417 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6418 inhibits top-level logging; debug scripts are created.
6420 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6421 check.
6422 * tests/autotest.at (Empty test, Empty check): New test to check it.
6424 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6425 from gcc.
6427 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6429 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6430 the files if a problem appears. Make the empty *.at files
6431 read-only, too. Proposed by Ralf Wildenhues.
6433 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6435 * config/Makefile.am: Add comment to force updated Makefile.in.
6437 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6438 space only patch to this file, this patch causes the Makefile.in
6439 files that include freeze.mk to be updated, and thus have a
6440 newer time stamp again, which in turn makes a pristine CVS
6441 checkout have correct time stamps.
6443 * Makefile.maint (cvs-sv): New macro, to be used..
6444 (config.guess-url_prefix, config.sub-url_prefix)
6445 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6446 point to CVS text checkout of Gnulib files.
6447 (copyright-check): Bump current year.
6448 (announcement): Do not hard-wire `./announce-gen'.
6449 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6450 correctly.
6451 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6452 `chmod +x'.
6453 (wget_files): Update config.guess, config.sub, texinfo.tex by
6454 `wget-update', now that their URLs work again.
6456 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6458 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6459 Problem noted by Paul D. Smith.
6461 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6463 * doc/autoconf.texi: Remove unused words from word list.
6464 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6465 .x-sc_trailing_space: New files.
6467 * doc/standards.texi: Sync from gnulib.
6469 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6470 `LIBOBJDIR' as experimental.
6472 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6473 with a target directory; it's internally implemented as `cp'
6474 anyway, but since Autoconf advertises the possibility to use
6475 a target directory when LN_S is `ln -s', we need to find out.
6476 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6477 analyzed by Keith Marshall <keith.marshall@total.com>.
6479 * THANKS: Update.
6481 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6483 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6484 confdefs.h as-is. In general, if it has backslash-newline or the
6485 like, then it doesn't work either to sort or to remove empty
6486 lines.
6488 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6490 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6492 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6494 * lib/autom4te.in (Automake-preselections): Preselect
6495 _AM_SUBST_NOTMAKE.
6497 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6499 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6500 apostrophe within a single-quoted string, as this is the usual
6501 tradition and is easier to read than '"'"'. Don't rely on the
6502 shell treating "$/" like '$/'. Use a more-consistent indenting
6503 style for the trap.
6505 2006-04-09 Eric Blake <ebb9@byu.net>
6507 * tests/autotest.at (Backquote command substitution),
6508 (Multiline backquote command substitution): Remove mistaken
6509 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6510 applied...

6592 _AS_DETECT_BETTER_SHELL:
6594 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6595 skip nonexistent directories.
6596 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6597 only shell candidates which exist.
6598 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6599 * lib/autotest/general.m4 (AT_INIT): No need to give three

6602 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6603 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6605 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6606 distinguish m4sugar macros.
6607 * tests/tools.at (autoupdating with aclocal and m4_include):

6609 test case by Noah Misch <noah@cs.caltech.edu>.
6611 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6613 Revert my change from 2006-03-17, in other words:
6614 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6615 and DUALCASE=1.
6616 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6617 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6618 it is set.
6620 2006-04-07 Eric Blake <ebb9@byu.net>
6622 * doc/autoconf.texi (Programming in M4sh): Document that
6623 AS_MKDIR_P exits the script on failure.
6624 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6626 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6628 * config/elisp-comp, config/install-sh, config/mdate-sh,
6629 config/missing, config/mkinstalldirs: Sync from Automake.

6645 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6647 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6648 whether `set' quotes correctly: redirect stderr of the tested
6649 `set', and use a subshell, for Ultrix; use `sed' instead of
6650 `grep' for zsh `set' which may write binary output; match only
6651 at the beginning of a line, to avoid false positives.
6652 In order to avoid false positives by unrelated variables with
6653 multiline content, put the dump algorithm in a subshell and
6654 unset all variables containing newlines (except some which are
6655 special to the shell). Warn about cache variables that are
6656 unset.
6658 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6669 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6670 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6671 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6672 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6674 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6675 shell issue with double-quoted command substitutions of native
6676 commands.
6677 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6678 Marshall.
6680 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6697 * tests/Makefile.am (maintainer-check-posix):
6698 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6700 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6701 ac_config_<foo>s again, sometimes normalized, sometimes not.
6702 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6703 (AC_CONFIG_COMMANDS): Do not do so here.
6704 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6705 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6706 2005-07-25 rewrite. Noticed by Noah Misch.
6708 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6709 _AC_PRESERVE_HELP_ORDER, ...
6710 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6712 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6713 inside m4_expand_once; it is redundant.
6715 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6716 for --help from Cygnus `configure.'
6718 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6731 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6732 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6733 * doc/autoconf.texi (Help Formatting): New node.
6734 * NEWS: Announce AC_PRESERVE_HELP_ORDER.

6758 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6759 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6760 normalizing it, consistent it with previous releases.
6761 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6763 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6765 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6766 Use simplified args that Eric Blake originally suggested.
6768 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6770 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6771 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6772 Use 'comm' rather than N instances of grep; this also fixes a bug
6773 whereby substrings were incorrectly matched, causing us to not
6774 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6775 (exclude_list): Exclude empty macros.

6788 a subdirectory subject to Cygnus `configure'.
6789 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6791 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6792 report request when we have no AC_PACKAGE_BUGREPORT.
6794 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6859 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6860 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6861 ac_file to the name of the default output file and call
6862 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6863 initial `rm' of the candidate files...
6864 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6865 the same list in subsequent `rm' calls, and for the temporary
6866 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,

6868 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6869 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6870 no longer needed) by libtool. Make it a cache check.
6871 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6872 copied here by mistake.
6873 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6874 _AC_COMPILER_EXEEXT.

6908 Autoconf version number despite a zero- or one-argument AC_INIT.
6910 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6911 subordinate tools.
6912 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6913 * doc/autoconf.texi (autoreconf Invocation): Document it.
6915 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

6927 the correct lines of the input file by subtracting..
6928 (_au__first_line): ..this new definition.
6930 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer

7648 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7649 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7650 by the function rather than ignoring it.
7651 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7652 comparing its address. Intel's interprocedural optimization was
7653 outsmarting the old heuristic. Problem reported by

7668 before removing it (chmod -R u+rwx); there are three instances of this.
7670 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7671 Stepan Kasal <kasal@ucw.cz>
7673 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7674 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7675 make its content writable before removing it. Remove an errorneous
7676 comment from the end, where the logs of the failed tests are copied
7677 to the main log file.
7679 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7681 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

7683 snippets.
7685 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7686 problems if the testsuite were running too fast.
7688 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7690 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7691 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7692 (which belong to Xt, not X itself). See Debian bug 327655.
7693 * NEWS: Mention this.
7695 2005-09-07 Stepan Kasal <kasal@ucw.cz>

7699 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7701 * config/move-if-change: Don't output "$2 is unchanged";
7702 suggested by Ben Elliston. Handle weird characters correctly.
7704 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7706 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7707 calls, so that the final expansion of this macro is shorter.
7708 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7709 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7710 the cleanup there. Use AS_VAR_* macros, to be more general.
7711 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7713 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7715 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7728 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7730 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7731 The previous patch didn't work, so try a better one.
7733 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7735 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7736 in the example. Reported by Bruno Haible.
7737 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7738 "if $undefined_var;" succeeds with my shell.
7740 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7741 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7742 but change the m4_divert_text to m4_divert_once.
7744 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7746 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7747 Work around bug in Solaris /usr/xpg4/bin/awk.
7748 The bug is present in at least Solaris 8 through 10.

7752 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7753 some evil values and relying on the fact that $* concatenates the
7754 parameters by the first character from IFS.
7756 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7757 Stepan Kasal <kasal@ucw.cz>
7759 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7760 first header appears, define AH_HEADER.
7761 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7762 Update limitations about when to call AC_CONFIG_HEADERS.
7763 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7764 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7765 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7766 ``Configuration Actions''; fix their index entries.
7768 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7769 options correctly. Process N-M as M-N if M is smaller than N.
7770 Process ranges correctly so that N-N will run only N.
7771 Sort and uniquify the tests that will be run. If there is more
7772 than one test, reinsert the banners for the tests.

7778 before passing the macro name to AH_TEMPLATE.
7780 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7781 now opens log after option processing; in particular, --version
7782 and --help do not touch config.log.

7794 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7795 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7796 Language cleanup.
7798 * doc/autoconf.texi (Defining Symbols, Changed Results):
7799 Prepend to LIBS, not append, in examples.
7801 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7803 When building in place, set srcdir="."; suggested by Tim Van Holder.
7805 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7806 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7807 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7808 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7809 does not mean "no --srcdir option".
7811 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7813 * tests/autoscan.at (autoscan): New file.
7814 * tests/suite.at: Use it.
7815 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7816 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7818 * tests/autotest.at (Keywords): Test keywords combinations.
7820 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7822 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7823 add "2>&1"; gzip 1.2.4 prints help on stderr.
7825 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7827 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7828 was pushdef'ed twice while popped only once. Push it only once.
7829 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7831 2005-07-26 Stepan Kasal <kasal@ucw.cz>

7840 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7841 "<tab>" in comment, so that the point is understandable.
7843 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7845 Rewrite substantial part of lib/autoconf/status.m4.
7846 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7847 and CONFIG_COMMANDS are not processed in four separate loops.
7848 Instead, there is one main loop. This alows that the common code
7849 is expanded only once, thus config.status (and configure) is smaller.
7851 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7852 the AC_LIST_FILES and cousins macros are no longer used.
7854 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7855 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7856 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7857 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7858 contain the initialization, nor the for loop, nor the associated
7859 commands; all these go to ...
7860 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7861 _AC_OUTPUT_CONFIG_STATUS.
7862 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7863 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7864 (_AC_OUTPUT_FILE): The creation of the sed script ...
7865 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7866 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7867 _AC_OUTPUT_MAIN_LOOP.
7868 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7869 _AC_CONFIG_COMMANDS): Use ...
7870 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...

7876 ... new macros.
7877 (_AC_CONFIG_UNIQUE): Update.
7878 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):

7883 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7884 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7885 this didn't belong to the `config commands' section.
7886 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7887 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7888 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7889 to the `config commands' section either.
7890 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7891 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.

7905 parameter to AC_DIAGNOSE.
7906 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7907 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7908 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7909 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7910 with AU::AC_OUTPUT.
7911 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7912 in AC_OUTPUT doesn't double-quote it either.
7913 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7914 parameters.

7938 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7939 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7940 (AC_ARG_VAR): ... here.

7952 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7953 to INIT_PREPARE.
7954 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7955 its value to shell variable ac_precious_vars and call
7956 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7957 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7958 _AC_ARG_VAR_VALIDATE.

7994 versions of autoconf.
7996 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7998 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

8003 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8004 sed substitution command, so that we allow | in program prefixes

8007 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8008 configure_input, top_builddir, srcdir, etc.
8009 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8010 PATH_SEPARATOR in AUTOTEST_PATH.
8012 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

8020 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
8021 directories with weird names. Apparently some people like living

8042 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8043 document to output the default config_* lists to config.status.
8044 Don't recognize option --file, if the functionality is not there.
8045 Likewise for --header; moreover, recognize --he and --h as shortcuts
8046 for --help in that case.
8048 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8049 matches the order of execution. No code changed.

8071 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8072 (AC_SUBST): Call it.
8073 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8074 the directory specific variables; but don't call it for configure_input.
8076 2005-06-28 Derek Price <derek@ximbiot.com>
8078 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8079 addition.
8081 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8083 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8084 directory have inherent problems with special characters like spaces,
8085 due to limitations in Make syntax. Problem reported by Alexandre
8086 Duret-Lutz.
8087 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

8102 variable into diagnostic. Make the diagnostic an error, not a warning,
8103 because we really don't support spaces and suchlike in dir names.
8104 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8105 Don't worry about backslashes in srcdir; it can't happen now.
8106 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8107 Simplify ac_optarg handling.

8122 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8124 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8130 2005-06-21 Stepan Kasal <kasal@ucw.cz>
8132 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8133 b, t, r, w commands require single space, while : cannot have any.
8134 (Special Shell Variables): Fix sed code this in the example.
8135 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8136 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8138 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
8139 expand to the empty list. Don't use two pairs of m4_changequote,
8140 it's not necessary.
8142 2005-06-20 Derek Price <derek@ximbiot.com>
8144 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

8148 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8149 * doc/autoconf.texi:
8150 Don't mention Solaris versions so much, if a
8151 problem is common to all extant versions of Solaris. Say "SunOS
8152 4" instead of "SunOS" for SunOS 4.
8153 (awk): Mention more of the limitations of traditional Awk.
8154 (cat): Don't talk about cat -v.
8156 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

8161 to be compatible with glibc strverscmp.
8162 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8164 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8165 on Mac OS X 10.4 reported by Peter O'Gorman in:

8167 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8168 Use shell builtins rather than 'expr', to work around expr bug.
8170 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8172 * doc/autoconf.texi: "filesystem" -> "file system".
8173 "behaviour" -> "behavior".

8186 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8187 quotes and backslashes. Patch from Derek Price.

8192 AS_TR_SH.
8194 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8196 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8197 -u, since it outputs chatter if the input files are the same.
8198 Problem reported by Ralf Menzel.
8200 2005-06-08 Derek Price <derek@ximbiot.com>
8202 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8203 renaming them since they are about to be redefined anyhow.
8205 2005-06-08 Derek Price <derek@ximbiot.com>
8207 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8208 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8209 Move m4_undefine to alphabetical order.
8211 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8213 * README: Recommend GNU M4 1.4.3 or later.
8214 * doc/autoconf.texi (Introduction): Likewise.
8215 Reword to avoid some formatting glitches.
8216 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8217 Clarify explanation of HP compiler bug.
8218 Redo example output tp match current CVS snapshot.
8219 Use @example.org in email addresses when the examples
8220 might get inadvertently cut-and-pasted into user code.
8221 Remove example of autom4te usage that doesn't seem to work now.
8222 Use modern AC_INIT (except when the example is meant to be
8223 shown with Autoconf 2.13).
8224 Update ksh info for Solaris 9 and later.
8225 KB -> kB.
8226 Modernize description of Automake versions a bit.
8227 Don't claim a future version of Autoconf is near.

8234 Reword to avoid some formatting glitches.
8235 * doc/installt.exi: Reword to avoid some formatting glitches.
8237 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8238 Tru64 ksh pattern matching bug. Reported against Libtool by
8239 Albert Chin <libtool@mlists.thewrittenword.com> and
8240 Nicolas Joly <njoly@pasteur.fr>.
8242 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8244 m4_cdr of one-member list was [[]] (one-member list containing an
8245 empty string) instead of [] (an empty list. Callers were skewed to
8246 match this misbehaviour. As a consequence of this:
8247 - m4_foreach([x], [], [foo]) expanded to `foo', while
8248 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8249 This bug has been fixed:
8251 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8252 expand to an empty string; print error msg if called without
8253 an argument list.
8254 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8255 misbehaviour; handle [] and [[]] correctly.

8263 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8265 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8266 swallow records with more than 99 fields.
8267 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8268 parse the long line.
8270 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8272 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8273 swallow literals longer than 399. Reported by Ralf Wildenhues.
8274 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

8277 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8279 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8280 to gfortran, and make these the first two compiler names
8281 checked (following the general autoconf preference for gcc).
8283 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8285 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8286 (DISTCLEANFILES): Remove $(check_SCRIPTS).

8291 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8292 expression of unbounded size when processing the --list
8293 option. This runs afoul of a limit of 399 bytes per regular
8294 expression on AIX. Problem reported by Ralf Wildenhues.

8305 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8307 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8308 now contain newlines, and substituted files must be referenced on
8309 a line alone; the sed scripts to substitute them are now very
8310 different.
8311 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8312 commands can be put in a sed script portably.
8313 * doc/autoconf.texi (Setting Output Variables): Document above

8321 From Ralf Menzel (trivial change).
8323 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8325 * tests/local.at: Don't attempt to check for negated character
8326 classes in shell scripts. The test was too brittle.
8328 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8330 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8331 * doc/autoconf.texi (Limitations of Builtins): Document this
8332 limitation.
8334 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8336 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8337 common code; used in many places in the tree.
8338 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8339 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8341 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
8343 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
8344 messages when ac_unique_file is not found.
8345 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8346 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8347 commands, for consistency with AC_MSG_ERROR and such.
8349 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8351 * bin/Makefile.am: Merge the two rules for creating scripts.
8353 2005-05-23 Stepan Kasal <kasal@ucw.cz>
8355 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
8356 obsolete; it was never documented.
8357 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
8359 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8361 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8362 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8363 (ac_top_builddir): ... this ...
8364 (ac_top_build_prefix): ... to this; the old name is also kept, for
8365 backward compatibility.
8366 (ac_top_builddir_sub): New variable, without the trailing slash,
8367 always nonempty.
8368 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8369 * doc/autoconf.texi (Configuration Actions): Rename
8370 ac_top_builddir to ac_top_build_prefix.
8371 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8372 at_top_builddir to at_top_build_prefix.
8373 * lib/autotest/general.m4 (AT_INIT): Likewise.
8375 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8377 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8378 of confdefs.h .
8380 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8382 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8383 argument to m4_foreach. I guess it was necessary in the past,
8384 but I think it's a no-op now.
8386 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8388 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8389 ``cat <<_ACEOF'' commands to one.
8390 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8391 * lib/autoconf/status.m4: On various places, use expr instead of
8392 ``echo|sed.''
8393 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8394 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8395 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8396 a range.
8397 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8398 the wrong patterns between ``case'' and ``esac.'' The previous
8399 code had false positives.
8401 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8403 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8404 as on 2005-05-02.
8405 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8406 Mention LIBOBJDIR.

8444 Update FSF postal mail address.
8446 2005-05-13 Stepan Kasal <kasal@ucw.cz>
8448 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
8449 check.
8450 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
8451 enough arguments, similarly as in m4_bpatsubsts.
8453 2005-05-12 Stepan Kasal <kasal@ucw.cz>
8455 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
8456 of absolute paths.
8458 2005-05-11 Stepan Kasal <kasal@ucw.cz>
8460 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
8461 for absolute directory names in one loop.
8462 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
8463 abbreviations of --version and --debug.
8465 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
8467 * doc/autoconf.texi (Autoconf Language): Be more precise about
8468 quoting rules. Problems noted by Stepan Kasal.
8469 Also, throughout this document, be more careful about white space.
8470 "blank", "white space", and "space" all have different meanings
8471 and we should be careful to say what we mean.
8473 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8475 Fix C++ related problems reported by Werner Lemberg.
8476 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
8477 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
8478 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
8479 avoid problems with C++ and throw.
8480 * tests/compile.at: .cpp, not .cc.
8482 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8484 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8486 * doc/autoconf.texi (Generic Functions): Typos.
8488 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8490 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8491 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8492 set by latest automake.
8494 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8496 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8497 outputs 0 on GNU/Linux these days.
8499 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8501 * doc/autoconf.texi (Autoconf Language): Add more description
8502 about quoting heuristics.
8503 (Limitations of Builtins): Describe "set -" problems.
8505 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8507 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8508 not newline.
8510 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8511 by AC_DEFINE; it was a mistake.
8512 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8514 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8516 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8518 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8520 * doc/autoconf.texi (External Software): Quadrigraphs are not
8521 processed correctly in AS_HELP_STRING; avoid this in the examples.
8522 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8523 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8524 comment and reduce m4_default([foo], []) to [foo].
8525 (m4_strip): Update the explanation.
8527 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8529 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8530 Remove core.conftest.* too; it's generated by Tru64 5.1.
8531 Problem reported by Jennis Pruett.
8532 * lib/autoconf/functions.m4
8533 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8534 Don't bother to remove core files; AC_RUN_IFELSE should do that
8535 for you.
8537 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8539 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8541 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
8543 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
8544 Report from Horst Wente.
8546 2005-04-15 Stepan Kasal <kasal@ucw.cz>
8548 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
8549 the comment.
8551 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8553 * doc/autoconf.texi (External Software, Package Options): Add
8554 examples showing how to implement --with-* and --enable-* options.
8556 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8558 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8559 as well as configure.in. Problem reported by Gregorio Guidi.
8561 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8563 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8564 pattern for alloca snippet.
8566 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8568 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
8570 2005-04-01 Stepan Kasal <kasal@ucw.cz>
8572 * doc/autoconf.texi (Generic Programs): Fix a typo.
8574 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8576 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8577 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8579 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8581 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8582 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8583 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8584 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8585 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8587 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8589 * NEWS: The configure command now warns you if you attempt to use
8590 a directory whose name contains a special character like space,
8591 newline, or "\".
8592 * doc/autoconf.texi (Installation Directory Variables): Allow
8593 "," in file names. Do not use \@; it's not a portable regexp.
8594 * bin/Makefile.am (edit): Likewise.
8595 * lib/Makefile.am (edit): Likewise.
8596 * tests/Makefile.am (edit): Likewise.
8597 * tests/semantics.at: Likewise.
8598 * tests/torture.at: Likewise.
8599 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8600 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8601 * doc/autoconf.texi (File System Conventions): Warn about
8602 unportable file names.
8603 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8604 (AC_INIT): Use it.
8605 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8606 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8607 ac_pwd, and quote srcdir.
8608 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8610 * doc/autoconf.texi: Fix some systematic formatting problems.
8611 ".)" needs a following @: if not at the end of a sentence, and
8612 similarly for "!)". "etc." should be preceded by a comma.
8613 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8615 2005-03-22 Bruno Haible <bruno@clisp.org>
8617 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8618 argument is often called 'build-aux'.
8620 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8622 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8623 macro AC_TRY_LINK is obsolete.
8624 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8625 `AC_CONFIG_FILES'.
8627 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8629 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8630 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8631 from a Common Lisp's `cl'.
8632 (AC_PROG_CXX): Behave according to the documentation: don't
8633 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8634 make the variable CCC precious; use `cl.exe', not `cl'.
8636 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8637 Alexandre Duret-Lutz <adl@gnu.org>
8639 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8640 /dev/null, as "configure" shouldn't read stdin, and this insulates
8641 us from problems (e.g., when testing for "cl"). Also, do this
8642 redirection before invoking "hostname" or "uname", and keep the
8643 original input stream available via...
8644 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8645 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8646 bother with "</dev/null" since it's now done at the top of
8647 'configure'.
8648 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8649 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8650 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8651 * doc/autoconf.texi (File Descriptor Macros): New section.
8652 (Printing Messages): Mention it.
8653 * tests/base.at (Input/Output): New test.
8655 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8657 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8658 newline if neither \c nor -n work, as that would output two
8659 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8661 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8663 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8664 This causes that any required macros inside will get before the if.
8665 * doc/autoconf.texi (autom4te.cache): A typo.
8667 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8669 Undo previous change, except keep the change to
8670 lib/autoconf/programs.m4 that replaced grep with shell
8671 pattern-matching. This is because net-snmp configure reads stdin.
8672 Reported by Noah Misch.
8674 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8676 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8677 from /dev/null, as "configure" shouldn't read stdin, and this
8678 insulates us from problems (e.g., when testing for "cl").
8679 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8680 before invoking "hostname" or "uname".
8681 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8682 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8683 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8684 "</dev/null" since it's now done at the top of 'configure'.
8685 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8686 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8687 Also, replace grep with shell pattern-matching, to save a process.
8689 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8691 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8692 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8693 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8694 compiler.
8696 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8698 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8699 grep -q isn't portable. Improve grep -s explanation.
8700 Problem reported by Dan Manthey.
8702 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8704 * doc/autoconf.texi (Special Shell Variables): Clarify
8705 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8707 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8709 * doc/autoconf.texi: Use @acronym for DJGPP.
8710 Fix some @code's that should have been @env's, and vice versa.
8711 Sort environment variable names.
8712 Mention that shells no longer inherit IFS.
8713 Don't recommend PATH_SEPARATOR=';' so strongly.
8714 Mention that $RANDOM might expand to the empty string.
8715 "symlink" and "soft link" -> "symbolic link".
8716 Improve mktemp description (reported by Bruno Haible).
8718 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8720 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8721 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8722 Likewise.
8723 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8724 Likewise.
8726 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8728 * NEWS: Mention AT_COPYRIGHT.
8730 * tests/local.at (AT_CMP): Use diff directly on input files rather
8731 than copying them.
8733 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8734 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8736 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8737 and Paul Eggert <eggert@cs.ucla.edu>
8739 * tests/autotest.at (Empty test suite): New test.
8740 * tests/torture.at (Substitute and define special characters)
8741 (Substitute a 2000-byte string, Define to a 2000-byte string)
8742 (Substitute a newline, Define a newline): New tests.
8744 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8746 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8747 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8748 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8749 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8750 (Standard regular expressions): New test.
8751 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8752 excess test name quoting.
8753 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8754 CPPFLAGS to `configure' instead of setting it in `configure'.
8756 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8757 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8758 on some platforms.

8792 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8794 Try not to generated lines of unlimited length, as POSIX places a
8795 2047-byte limit on line length of portable text files.
8796 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8797 Use newline as a separator, not space.

8855 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8856 Update the long comment explaining it.
8858 m4_require no longer writes an ``is required by'' line to the
8859 execution stack. It contains only one bit of non-redundant
8860 information: that the macro was required, not called. And even
8861 this bit is useless in most situations: have you ever met a macro
8862 which both calls and requires the same macro?
8864 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8865 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8872 (_m4_require_call): Use it.
8873 * tests/m4sugar.at (m4_require): Expect output without the
8874 ``is required by'' messages.
8876 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8878 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8879 rather than x for expr.
8881 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8882 this is safe.
8883 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8884 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8899 config.h.in is always recreated when --force.

8905 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8907 * doc/autoconf.texi (Limitations of Builtins): Clarify that

8910 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8912 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8913 Warn about newline stripping in `` and $(). Update Solaris
8914 version to 9.

8916 X insulates us from future changes to Posix.
8917 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8918 stripping.
8920 2005-01-19 Stepan Kasal <kasal@ucw.cz>

8940 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8942 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8944 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8966 (_m4_divert_n_stack): New macro; the expansion is
8967 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8968 otherwise.
8969 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8970 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8971 stored in _m4_divert_diversion or _m4_divert_dump.
8972 (m4_divert_pop): When the parameter is given, compare the symbolic
8973 name with the last diversion pushed on the stack. Previously, the
8974 current diversion was compared with the numeric value of the
8975 diversion given as the parameter.
8976 (m4_require): If the macro hasn't been expanded yet, call ...
8977 (_m4_require_call): this new macro.

9010 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

9012 not essential. Reported by Magnus Therning.
9013 * tests/torture.at (autoreconf.): New banner.
9014 (autoreconf and non-AC configure): Rename to `Non-Autoconf

9063 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
9064 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

9226 * doc/autoconf.texi (Libraries): Clarify problems with AC_CHECK_LIB
9227 and suggest AC_SEARCH_LIBS. Suggested by Noah Misch and Stepan Kasal.
9229 2004-12-08 Noah Misch <noah@cs.caltech.edu>
9231 * configure.ac (test suite): Cease to generate wrapper scripts.

9236 (wrapper.in): Generate it in the build directory.
9237 (MAINTAINERCLEANFILES): Delete wrapper.in.
9238 (CLEANFILES): Add wrapper.in.
9239 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
9240 the output. Replace each $as_me with a @wrap_program@.
9241 * tests/wrapper.in: Delete it; we always build it.
9243 * bin/Makefile.am (autoconf.in): Generate it in the build directory.

9256 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9258 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
9259 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
9260 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
9261 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
9263 2004-12-07 Stepan Kasal <kasal@ucw.cz>
9265 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

9277 out the common code to ...
9278 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
9279 value of the #define--default to 1, iff the macro was called
9280 with exactly one parameter.
9282 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
9284 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9285 "char c = '\200';" rather than "char c = 0x80;" as the
9286 latter doesn't conform to the strict C standard due to
9287 overflow on signed char hosts.
9289 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
9290 to -qlanglvl=ansi. We don't want to disable extensions.
9292 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
9294 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

9350 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9351 the $1_found variable, don't test whether the file is executable;

9389 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9390 Problem reported by Stepan Kasal.
9392 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
9394 Fix problems reported by Andreas Buening in:
9395 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
9396 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9397 in test makefile.
9398 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9399 readable; it's not true in OS/2-emx.
9401 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9403 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9404 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9405 (trivial change). Problem and patch reported by Andrew Church in:
9406 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9408 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

9435 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9436 texinfo.tex for now (done by hand now).
9437 * Makefile.maint (wget_files, cvs_files):
9438 Remove ansi2knr.c; nobody uses it.
9439 (ansi2knr.c-url_prefix): Remove.
9440 (cvs-update): Fix test for failure. I don't know why it ever
9441 worked...
9443 * doc/autoconf.texi: Update URLs, some of which went stale.
9444 Use @uref rather than @href.
9446 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9447 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9449 * config/config.guess, config/config.sub, config/elisp-comp,
9450 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9451 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9453 * NEWS, TODO, configure.ac, bin/autoscan.in,
9454 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
9455 doc/install.texi, lib/Autom4te/Configure_ac.pm,

9459 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9460 tests/tools.at, tests/torture.at:
9461 Use "file name" rather than "filename" or "path",
9462 to be consistent with the terminology of the GNU coding standards.
9464 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9466 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9467 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9468 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9469 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9471 More fixes to support spaces in the name of the build directory.
9472 This isn't a complete fix but it's an improvement.
9474 * bin/autoconf.as (autom4te_options): New var.
9475 Use it instead of appending to AUTOM4TE, so that we can allow
9476 spaces in the build directory's absolute name.
9477 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9478 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

9481 main program): Likewise.
9483 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9485 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

9489 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9491 * doc/autoconf.texi (Function Portability): Document isinf and
9492 and isnan. From a suggestion by Kevin Ryde.
9494 * lib/Autom4te/General.pm (END): Return correct exit status even
9495 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9497 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9499 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9500 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9501 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9503 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9505 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9506 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9507 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9508 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9509 * lib/autom4te.in (Automake-preselections): Preselect
9510 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9512 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9514 * lib/autom4te.in (Automake-preselections): Preselect
9515 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9516 trace them.
9518 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9520 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9521 Tru64.
9522 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9523 Document problem with "`""`" in pdksh POSIX mode.
9525 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9527 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9528 with pdksh, too. Problem reported by Patrick Welche via
9529 Gary V. Vaughan.
9530 * doc/autoconf.texi (Shellology): Note that set -o posix is
9531 useful for pkdsh, too.
9533 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9535 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9536 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9537 Don't fail if ENV or BASH_ENV is readonly.
9538 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9539 etc. are read only. Problem reported by Ludovic Courtes.
9541 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9543 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9544 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9545 (trivial change)
9547 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9549 * doc/autoconf.texi (File System Conventions): Warn about
9550 names like "aux". Problem reported by Eric Blake.
9552 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9553 by zero instead of array size, so that we can use any arithmetic
9554 constant expression (instead of requiring an integer constant
9555 expression). This allows us to test expressions like DBL_MAX <
9556 LDBL_MAX, which didn't conform to the C standard using the old
9557 method.
9558 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9559 now that we can do floating-point tests at compile time.
9561 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9563 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9564 and LDBL_EPSILON, as the resulting expression isn't an
9565 integer constant expression and violates the C standard.
9566 Problem reported by Nelson H. F. Beebe. Also, check
9567 for "L" suffix, and check that long double doesn't have
9568 worse range or precision than double, that mixed-mode
9569 arithmetic doesn't generate a diagnostic, that double
9570 constants fit in long double.
9572 2004-06-03 Kevin Ryde <user42@zip.com.au>
9574 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9575 malloc(0) and realloc(NULL,size).
9577 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9578 Bob Proulx.
9580 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9582 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9583 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9584 by Jim Meyering.
9586 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9588 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9589 can be rewritten using if-then-else. Suggested by Bruno Haible.
9591 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9593 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9594 Problem reported by Stepan Kasal.
9596 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9598 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9599 change). Patch reported by Ralf Wildenhues in
9600 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9602 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9603 function F exists if the compiler and linker let you compile an
9604 expression like (F != 0). Recent versions of GCC optimize away
9605 the reference to F in that case, since every function address must
9606 be nonzero, so the link succeeds even if F does not exist.
9607 Problem reported by Manu in
9608 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9610 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9611 "Unix". Many uses changed.
9612 (Limitations of Builtins): Explain better why the ! command isn't
9613 portable.
9615 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9617 * lib/autom4te.in (Automake-preselections): Preselect
9618 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9620 2004-05-19 Kevin Ryde <user42@zip.com.au>
9622 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9623 referencing AC_FUNC_STRERROR_R.
9625 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9626 note pessimistic assumption when cross compiling.
9628 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9630 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9631 (until 2004) invoked subcommands with sh -e, contra POSIX.
9632 Reported by Kevin Ryde.
9634 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9636 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9637 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9638 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9639 `test -f " /usr/bin/grep"', which _always_ failed.
9640 (AC_PROG_SED): Ditto bogus PATH fix.
9641 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9642 requires that grep correctly supports _multiple_ `-e' options, rather
9643 than stating only that grep should accept `-e'.
9645 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9647 Port to C99, which requires that 'exit' be declared.
9649 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9650 to ensure that stdlib.h is included.
9651 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9652 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9653 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9654 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9655 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9656 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9657 when using 'exit' in a test; C99 requires that 'exit' be declared.
9659 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9661 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9662 now prefers 'grep' implementations that accept -e.
9663 (Limitations of Usual Tools): Describe problems of traditional
9664 egrep and fgrep with long input lines, and of traditional grep
9665 with -e.
9666 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9667 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9668 All callers changed. Append /usr/xpg4/bin to the PATH, for
9669 Solaris.
9670 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9671 the user with complaints about multiple -e options.
9672 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9673 Define it with AC_PROG_GREP.
9674 * configure.ac (AC_PROG_GREP): Add.
9675 * lib/freeze.mk (GREP): New macro.
9677 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9679 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9680 a possible candidate only after all others fail, rather than
9681 consulting it first. This improves backward compatibility by
9682 better reflecting the way shell selection occurred in previous
9683 versions of Autoconf, and should help to avoid triggering latent
9684 problems in other packages, such as the one in Automake where zsh
9685 is not handled robustly:
9686 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9687 Although it is not Autoconf's responsibility to work around
9688 problems in Automake, it nevertheless makes sense to avoid
9689 introducing unnecessary incompatibilites.
9691 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9692 Gary V. Vaughan <gary@gnu.org>
9694 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9695 how deeply nested we are when a suitable tool is found, set the
9696 ac_path_TOOL_found flag.
9697 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9698 nested we are in this macro. Break out of all 3 nested loops if
9699 ac_path_TOOL_found is set.
9701 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9703 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9704 of the _AS_PATH_WALK loop too if GNU flavor is found.
9706 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9708 * doc/autoconf.texi (Limitations of Make): Update documentation
9709 for `$<'. New entry `Long lines', based on a report from Simon
9710 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9711 paragraph about DJGPP, based on a mail from Richard Dawe.
9713 2004-04-20 Paul Eggert <eggert@twinsun.com>
9715 * tests/c.at (C keywords): Don't assume that GCC supports
9716 "restrict" and "inline", as sufficiently-old GCC versions do not
9717 (also, GCC configured to be in pedantic C89 mode does not).
9718 Problem reported by Sumit Pandya in:
9719 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9721 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9722 consider -g to work if it generates warnings when plain compiles
9723 don't. Problem reported by Braden McDaniel in:
9724 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9726 * doc/autoconf.texi (Slashes): New section, to document a problem
9727 reported by Jim Meyering in:
9728 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9730 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9731 linker output files before linking, to work around IRIX 6 linker bug.
9732 Problem reported by Rainer Orth in:
9733 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9735 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9737 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9738 best tool so far counter rely on the tool path variable name to
9739 avoid checks for one tool being affected by the results of running
9740 the length check on a previous tool.
9742 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9743 match expression argument, as different greps have different
9744 regular expression flavours.
9745 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9746 literals.
9747 (AC_PROG_EGREP): Pass 'EGREP$'.
9748 (AC_PROG_GREP): Pass 'GREP$'.
9750 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9752 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9753 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9755 2004-03-29 Paul Eggert <eggert@twinsun.com>
9757 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9758 Types, Specific Compiler Characteristics, System Services,
9759 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9760 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9761 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9762 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9763 Likewise.
9764 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9765 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9766 AC_TYPE_OFF_T): Likewise.
9767 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9768 Likewise.
9770 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9771 pacify libtool 1.5.2. Fix quoting problems in sed command.
9773 2004-03-28 Paul Eggert <eggert@twinsun.com>
9775 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9776 now defines HAVE_DECL_TZNAME if it is declared, when
9777 HAVE_STRUCT_TM_TM_ZONE is not defined.
9778 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9779 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9780 for HAVE_TZNAME.
9782 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9784 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9785 superfluous backslashing of quotes (") in sed expressions;
9786 thanks to Paul Eggert.
9788 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9790 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9791 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9792 H. F. Beebe for the bug report.
9794 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9796 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9797 quoted -cmdline argument in Portland Group compiler (bug
9798 reported by Jeffrey J. Barteet).
9800 2004-03-25 Kevin Ryde <user42@zip.com.au>
9802 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9803 (Run Time): ... here, where it's now mentioned.

9807 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9808 inherits from language Autoconf-without-aclocal-m4.
9809 (Customizing autom4te): Adjust example; the cache must now be
9810 disabled for language Autoconf-without-aclocal-m4.
9812 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
9813 Nathanael Nerode <neroden@twcny.rr.com>

9823 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
9824 AC_CHECK_TOOLS.
9825 (Specifying Names): Document the reason for these future
9826 behavioral changes.
9827 * tests/mktests.sh: Do not generate tests for the
9828 new macros.
9829 * NEWS: Document these changes.
9831 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9832 they make TeX hang up.
9834 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9836 * NEWS: New macro AC_CHECK_ALIGNOF.
9837 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9838 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9839 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9840 vowel.
9841 (AC_CHECK_ALIGNOF): New macro.
9842 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9843 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9844 those for sizeof.
9846 2004-03-03 Paul Eggert <eggert@twinsun.com>
9848 * bin/Makefile.am (edit): Don't use $< in a context where
9849 POSIX doesn't require support for it. Use $@.in instead.
9850 Problem reported by Anthony N. Frasso in
9851 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9852 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9854 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9856 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9857 from the next generation of Libtool.
9858 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9860 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9862 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9863 is not always thread-safe. Report from Nathanael Nerode.
9865 2004-02-18 Paul Eggert <eggert@twinsun.com>
9867 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9868 problem on QNX reported by Stephen Rasku in
9869 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9871 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9872 $(m4sh_m4f_dependencies); this removes a FIXME.
9873 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9874 (MAINTAINERCLEANFILES): Split into pieces,
9875 one per related section. Add $(srcdir)/wrapper.in.
9877 2004-02-09 Paul Eggert <eggert@twinsun.com>
9879 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9880 AC_SUBST provides no portable way to escape literal newlines.
9882 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9883 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9884 Darwin uses -lcrt2.o and there's little point to cataloging all
9885 the system variants. Partial fix reported by Andreas Waechter in:
9886 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9887 for bug reported by Nelson H. F. Beebe in:

9890 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
9892 * doc/autoconf.texi (AU_DEFUN): Fix English,
9893 suggested by Paul Eggert.
9894 * lib/autoconf/autoupdate.m4: Correct reference to
9895 acobsolete.m4, suggested by Alexandre Duret-Lutz.
9897 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
9899 * bin/autoupdate.in: Define __file__ so that warnings
9900 refer to the correct file.
9901 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9902 the behavior of the third argument.
9903 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9904 correctly the behavior of the third argument. Document
9905 what the three macros that AU_DEFUN defines do. Fix
9906 warning message when the third argument includes $0
9907 (reported by Alexandre Duret-Lutz).
9909 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9910 Eric Sunshine <sunshine@sunshineco.com>
9911 Paul Eggert <eggert@twinsun.com>
9913 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9914 (AS_INIT): Output shell initialization there. Removed optional
9915 parameter. Expand _AS_SHELL_FN_SPY.
9916 (AS_INIT_WITH_SHELL_FN): Removed.
9917 (_AS_SHELL_FN_SPY): New macro.
9918 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9919 macros.
9920 (AS_SHELL_SANITIZE): Remove loop to find better shell
9921 and documentation for the parameter.
9922 (_AS_DETECT_BETTER_SHELL): Move it here.
9923 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
9924 (_AS_RUN): Move it here, support testing with eval.
9925 (AS_REQUIRE_SHELL_FN): Require shell functions when
9926 it is used.
9927 (_AS_LINENO_WORKS): Put around braces, we do not
9928 trigger the bash bug anymore.
9929 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9930 use AS_INIT_WITH_SHELL_FN.
9931 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9933 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9935 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
9936 * doc/autoconf.texi: Don't say that the third parameter
9937 is broken.
9938 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
9939 (AU_DEFUN): Honor the third parameter, create autoupdate
9940 macros with AU_DEFINE.
9941 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9942 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
9943 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
9944 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
9945 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

9947 AC_XENIX_DIR): Likewise.
9948 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
9949 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
9950 * lib/autoconf/status.m4: Remove FIXME.
9951 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
9952 that the macro is not present anymore in the updated
9953 configure.ac.
9954 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
9955 of autoupdate.
9957 2004-01-28 Paul Eggert <eggert@twinsun.com>
9959 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
9960 copyright years.
9961 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9962 2003 (except 1997) to the list of copyright years. This undoes
9963 the 2003-05-22 change, which removed the older years from the list.
9964 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9966 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9967 Albert Chin-A-Young <china@thewrittenword.com>
9969 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
9970 grep or ggrep program in PATH that accepts as long lines as
9971 possible.
9972 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
9973 AC_PROG_GREP.
9974 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
9975 egrep and fgrep respectively if $GREP -E/-F don't work.
9976 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9977 _AC_PROG_GREP, and AC_PROG_SED.
9978 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9979 longest input length accepted by a command.
9980 (AC_PROG_SED): Use it.
9981 * doc/autoconf.texi (Particular Programs): Document the changes.
9982 * NEWS: Updated.
9984 2004-01-27 Paul Eggert <eggert@twinsun.com>
9986 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
9987 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9988 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9989 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9991 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9992 bin/autoconf.in, config/Makefile.in, config/config.guess,
9993 config/config.sub, config/install-sh, config/mdate-sh,

10006 sources.
10008 2004-01-26 Paul Eggert <eggert@twinsun.com>
10010 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10011 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10012 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10013 not <inttypes.h>. Problem reported by Tim Mooney in
10014 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10015 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10016 Likewise.
10018 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10019 otherwise "make check" fails because it forbids cmp (I guess
10020 because cmp treats files as binary on DOS-like systems).
10022 * tests/mktests.sh: Update copyright date to 2004, since some tests
10023 have changed in 2004.
10025 2004-01-23 Gary V. Vaughan <gary@gnu.org>
10027 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
10028 non-truncating sed or gsed program in PATH.
10029 * tests/acprograms.at: Add it.
10030 * doc/autoconf.texi (Particular Programs): Document it.
10031 * NEWS: Updated.
10033 2004-01-15 Paul Eggert <eggert@twinsun.com>
10035 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10036 -std1 disables some useful extensions on Tru64. Problem reported
10037 by N. Lichtmaier in
10038 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10040 2004-01-14 Paul Eggert <eggert@twinsun.com>
10042 * doc/autoconf.texi (Programming in M4sh): Document that
10043 AS_MKDIR_P succeeds if the destination is a symbolic link
10044 to an existing directory.
10045 (Limitations of Usual Tools): Note that mkdir -p might not
10046 succeed on symlinks to directories.
10048 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10050 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10051 * bin/autoheader.in: Grammar fix in message.
10052 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10053 Test for dir before calling mkdir -p. (trivial changes)
10055 2004-01-13 Eric Blake <ebb9@byu.net>
10057 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10058 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10060 2004-01-10 Jim Meyering <jim@meyering.net>
10062 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10064 2004-01-09 Paul Eggert <eggert@twinsun.com>
10066 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10067 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10068 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10069 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10070 AC_COMPILE_IFELSE, since we now assume our caller invokes
10071 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10072 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10073 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10074 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10076 2004-01-07 Paul Eggert <eggert@twinsun.com>
10078 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10079 `"'...'"`, as it's confusing (and I suspect it may not work on
10080 some platforms). The code was incorrect anyway, as it assumed
10081 that \$ evaluated to itself in that context. Reported by
10082 Alexandre Duret-Lutz.
10084 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10086 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10087 and _LT_AC_TAGCONFIG.
10089 2004-01-06 Paul Eggert <eggert@twinsun.com>

10555 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the

10561 2003-09-26 Akim Demaille <akim@epita.fr>
10563 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10564 Reported by Ralf Corsepius.
10566 2003-09-26 Akim Demaille <akim@epita.fr>
10568 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10569 arguments.
10570 Actually, use AU_ALIAS.
10571 From Bruno Haible.
10573 2003-09-26 Paul Eggert <eggert@twinsun.com>
10575 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
10576 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
10577 Problem reported by Eric Sunshine in:

10582 The test suite are sometimes assigning timings incorrectly.
10583 Reported by Henk Krus.
10584 Diagnosed by Nicolas Joly.
10586 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10587 AT_help_all.
10588 Instead of making AT_help a sequence of assignments to grow
10589 $at_help_all, just make AT_help_all be the growing contents of
10590 $at_help_all, and make a single assignment in...
10591 (AT_INIT): here.
10592 (at_times_skip): Flip the meaning and rename as...
10593 (at_times_p): this.
10594 (AT_INIT): When summarizing the test that ran, remove
10595 $at_times_file after use, and check it is present before trying to
10596 use it.
10598 2003-09-25 Akim Demaille <akim@epita.fr>
10600 Version 2.57d.
10602 * bin/Makefile.am (edit): Handle '@configure_input@'.
10603 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10604 (ifnames): chmod -w.
10605 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10606 executables, not bin/ executables! Otherwise all the magic needed
10607 to find non installed files is turned off. This caused a failure
10608 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10609 as found in its environment (sent by tests/autoreconf): pointing
10610 to bin/autom4te that could not find its files.
10611 * tests/mktests.sh: Force the replacement of generated files, for
10612 the sake of "mv" program that are interactive when overwriting a
10613 -w file.
10614 * config/install-sh: Upgrade from CVS Automake.
10616 2003-09-23 Paul Eggert <eggert@twinsun.com>

10619 versus test -L issues.
10621 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10622 Paul Eggert <eggert@twinsun.com>
10624 Trivial change to support GCC's configuration procedure.
10625 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10626 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10627 about inconsistency if the preprocessor is set to give errors for
10628 any warning.
10629 * doc/autoconf.texi (C Compiler Characteristics): Document this.
10631 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
10633 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
10634 and XFile.pm from Automake.
10635 * lib/Autom4te/XFile.pm: Update from Automake.

10644 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
10645 from masters.
10647 2003-09-12 Akim Demaille <akim@epita.fr>
10649 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
10650 not asm/types.h.
10652 2003-09-11 Akim Demaille <akim@epita.fr>
10654 * doc/autoconf.texi (Header Portability): linux/random.h.
10655 From Peter Hendrickson.
10657 2003-09-10 Akim Demaille <akim@epita.fr>
10659 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10660 willing to edit the output files.
10662 2003-09-10 Akim Demaille <akim@epita.fr>
10664 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10665 and AC_FC_FREEFORM.
10666 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10667 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10669 2003-09-09 Akim Demaille <akim@epita.fr>
10671 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
10672 Reported by Gary Vaughan.
10673 * bin/autom4te.in (handle_m4): Likewise.
10675 2003-09-09 Akim Demaille <akim@epita.fr>
10677 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
10678 trailing files.
10680 2003-09-07 Paul Eggert <eggert@twinsun.com>
10682 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10683 Improve the accuracy of the wording about obsolescence.
10684 From a suggestion by Ian Lance Taylor in
10685 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10687 2003-09-05 Paul Eggert <eggert@twinsun.com>
10689 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10690 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10692 2003-09-04 Akim Demaille <akim@epita.fr>
10694 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10695 AC_FUNC_WAIT3.
10697 2003-09-04 Akim Demaille <akim@epita.fr>
10699 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10700 (freeze): When exiting, use $exit_code.
10701 * lib/autoconf/fortran.m4: Comment changes.
10703 2003-09-04 Akim Demaille <akim@epita.fr>
10705 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10707 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10709 Add support for newer Fortran dialects. The F77 interface is
10710 unchanged, and continues to support Fortran 77. New FC macros
10711 correspond to all the old F77 macros, with output variables FC,
10712 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10713 available dialect, but older dialects can be specified. There are
10714 new macros AC_FC_SRCEXT to set the source extension, and
10715 AC_FC_FREEFORM to accept free-form source files.
10717 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10718 New macros.
10719 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10720 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10721 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
10722 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

10731 AC_FC_SRCEXT, AC_FC_FREEFORM):
10732 New macros.
10733 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
10734 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10735 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10736 Rewrite in terms of the above.
10737 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10738 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
10739 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
10740 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10742 2003-09-02 Paul Eggert <eggert@twinsun.com>
10744 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10745 Document problems with timestamp resolution that 'make', 'cp -p', and
10746 'touch -r' have.
10748 2003-08-27 Akim Demaille <akim@epita.fr>
10750 * tests/m4sugar.at (cross_warning): Make sure to enable the
10751 output, so that we can track spurious m4sugar output.
10752 * tests/local.at: Require 2.57.
10753 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10754 are defaulted by AT_CHECK anyway.
10755 Use AT_CHECK_AUTOM4TE.
10756 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10757 missing dnl.
10759 2003-08-27 Akim Demaille <akim@epita.fr>
10761 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10762 when -Wobsolete is set.

10810 Output stack traces in warnings.
10812 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10813 Replace the former...
10814 (m4_warn): Pass the call stack to _m4_warn.
10815 * bin/autom4te.in: Adjust to output the call stack.
10816 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10818 2003-08-22 Akim Demaille <akim@epita.fr>

10835 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10836 &parse_WARNINGS.
10837 ($help): Use Autom4te::ChannelDefs::usage.
10838 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10839 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10841 2003-08-21 Akim Demaille <akim@epita.fr>
10843 First stab at preserving warnings between calls to autom4te,
10844 including when the cache is used.
10846 There are still several issues: (i) there are too many runs of m4
10847 (one for include, one for warnings, and some more), (ii) warnings
10848 spreading on several lines are not handled gracefully, (iii) the
10849 code meant to have the call stack display for errors does not work
10850 (its handling should move from m4 to autom4te).
10852 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10853 Use them.
10854 (@preselect): Add m4_warn.
10855 ($exit_status): Remove, use $exit_code.
10856 ($help): Use Autom4te::ChannelDefs::usage.
10857 (&handle_m4): No longer define the m4_warnings.
10858 At each run, extract and report the warnings.
10859 Always cache the result, including if the exit status is on
10860 failure, since if nothing changes, we should result in the same
10861 failure, hence we can use the cache.
10862 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10863 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10864 Remove.
10865 (m4_warn): Redefine as a do-nothing: it is its invocation that
10866 matters, as warnings are now reported via traces.
10867 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10868 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10869 the latter reveals calls to the former.
10871 Adjust the tests.
10873 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10875 2003-08-21 Akim Demaille <akim@epita.fr>
10877 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10878 Use them.
10880 2003-08-21 Akim Demaille <akim@epita.fr>
10882 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10883 forward order.
10884 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10885 (&parse_warnings): Accept a list of warning requests.
10886 (&usage): Return a string, not a side effect.
10887 (cross): New warning category.
10889 2003-08-21 Akim Demaille <akim@epita.fr>
10891 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10892 (&require_configure_ac): Accept an optional directory argument.
10893 ($configure_ac): Remove.
10894 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10895 (&catfile): Remove.
10896 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10897 * bin/autoscan.in: Adjust.
10899 2003-08-20 Akim Demaille <akim@epita.fr>
10901 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10902 Reported by Alexandre Duret-Lutz.
10904 2003-08-20 Akim Demaille <akim@epita.fr>
10906 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10907 * bin/autom4te: Adjust.
10908 In particular, be Autoconf tools are really silent when properly
10909 working, bind the verbosity of the 'note' channel to $verbose.
10910 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10911 (&xsystem, &contents): Remove, since they are exported by...
10912 * lib/Autom4te/FileUtils.pm: this.
10913 More perldoc.
10914 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10915 * lib/Autom4te/FileUtils.pm: here.
10917 2003-08-20 Akim Demaille <akim@epita.fr>

10926 (autom4te-update): New.
10927 * Makefile.cfg (update): Bind autom4te-update.
10929 2003-08-19 Derek Price <derek@ximbiot.com>

10932 (PARSE_ARGS_BEGIN): New section for option parsing related
10933 initialization.
10934 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
10935 package specific options and associated help.
10937 2003-08-19 Akim Demaille <akim@epita.fr>
10939 * config/announce-gen, Makefile.cfg: New.

10970 2003-08-14 Derek Price <derek@ximbiot.com>
10972 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10973 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10974 shorter column three. Add DESCRIPTION to log file content.
10976 2003-08-13 Derek Price <derek@ximbiot.com>
10978 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

11011 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
11012 'long', not 'int', for benefit of Sun's recent C++ compilers
11013 (trivial change). See:
11014 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
11015 (This really should be 'intptr_t', not 'long', but that would
11016 take more work.)
11018 2003-06-25 Akim Demaille <akim@epita.fr>
11020 * lib/Makefile.am (autom4te.cfg): Make it read only.
11021 Depend on Makefile since it contains substitutions.
11022 From Paolo Bonzini.
11023 * lib/autom4te.in (args): Add local.at? for Autotest args.
11024 This change was made on autom4te.cfg which is generated.
11025 Reported by Raja R. Harinath.
11027 2003-06-25 Akim Demaille <akim@epita.fr>
11029 * doc/autoconf.texi (Header Portability): sys/mount.h.
11030 From Gareth McCaughan.
11032 2003-06-23 Akim Demaille <akim@epita.fr>
11034 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11035 not all of them. This fixes 1. the fact that when testing
11036 Autoconf there are many many config.log, 2. the incorrect use of
11037 top_srcdir to find config.log.
11038 Don't mix the detailed output of failed test with the summary of
11039 failures. Rather, append detailed log afterwards.
11041 2003-06-23 Akim Demaille <akim@epita.fr>
11043 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11044 always run: output config.log on $at_group_log.
11046 2003-06-23 Akim Demaille <akim@epita.fr>
11048 * tests/torture.at (#define header templates): Don't use quotes in
11049 C++ comments as it puzzles Emacs' sh font-lock-mode.
11051 2003-06-23 Akim Demaille <akim@epita.fr>
11053 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
11054 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
11055 * tests/atspecific.m4: Rename as...
11056 * tests/local.at: This.
11057 * tests/suite.at: Move the globals into...
11058 * tests/local.at: here.
11059 * tests/Makefile.am: Adjust.
11060 * doc/autoconf.texi (testsuite Scripts): Adjust.
11062 2003-06-21 Kevin Ryde <user42@zip.com.au>
11064 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11065 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11066 ensuring we add -std1 for full-ANSI.
11068 * doc/autoconf.texi (hdrindex): New macro.
11069 Add index entries for portability of various standard header files.
11071 2003-06-20 Akim Demaille <akim@epita.fr>
11073 * configure.ac: Bump to 2.57b.
11075 2003-06-20 Akim Demaille <akim@epita.fr>
11077 Version 2.57a.
11079 2003-06-20 Akim Demaille <akim@epita.fr>
11081 * bin/autom4te.in: Don't rely on $HOME being defined.
11082 Reported by Marc Espie as PR/233.
11084 2003-06-20 Akim Demaille <akim@epita.fr>
11086 * lib/autotest/general.m4: Use at_times_file only if used.
11087 From Nicolas Joly.
11089 2003-06-20 Akim Demaille <akim@epita.fr>
11091 * config/config.guess, config/config.sub, config/elisp-comp,
11092 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
11093 Update from masters.
11095 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
11097 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
11098 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
11099 (TEST_SCRIPT): New diversion.
11100 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
11101 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11102 (AT_INIT): Support for expected failures.
11104 2003-06-02 Akim Demaille <akim@epita.fr>
11106 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
11107 changes.
11108 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
11109 Autoconf nor Automake.
11110 (&contents): New, from Automake.
11111 PODify.
11113 2003-05-28 Paul Eggert <eggert@twinsun.com>
11115 * NEWS, doc/autoconf.texi (Particular Functions),
11116 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11117 is the inverse of localtime.
11119 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11121 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11122 (handle_exec_errors): New function. Work around $! being
11123 altered by WEXITSTATUS.
11124 (xqx, xsystem): Use handle_exec_errors.
11126 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11128 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11129 Do not call `_exit()', simply modify `$?'.
11130 (xsystem): Reset $! before running system, and check it afterward.
11131 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11132 63 for version mismatches.
11134 2003-05-23 Akim Demaille <akim@epita.fr>
11136 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11137 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11138 the middle of a line).
11139 * lib/m4sugar/m4sugar.m4: Likewise.
11140 Remove useless spaces in comments.
11142 2003-05-23 Akim Demaille <akim@epita.fr>
11144 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11145 exit 63, so that we (or Automake's "missing") can tell the
11146 difference with a plain failure.
11147 * doc/autoconf.texi (Notices): Adjust.
11149 2003-05-23 Akim Demaille <akim@epita.fr>
11151 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11152 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11153 White spaces cleanup.
11155 2003-05-22 Jim Meyering <jim@meyering.net>
11156 Paul Eggert <eggert@twinsun.com>
11158 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11159 Remove `#include <stdlib.h>' from the list; we should never
11160 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11161 resulting namespace pollution would cause other tests to fail.
11162 Configure scripts run with some older versions of g++ and HP's
11163 aCC would fail due to such an #include. Problems reported by
11164 Matthew Mueller in <http://bugs.debian.org/120704> and by
11165 Keith Bostic in
11166 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11167 In the test, use the test declaration before including <stdlib.h>,
11168 as that's closer to how it'll be used.
11170 2003-05-23 Akim Demaille <akim@epita.fr>
11172 * doc/autoconf.texi (Header Portability): ucred.h.
11173 From Ian Redfern.
11175 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11177 Overhaul Autotest's logging: generate separate log files
11178 in testsuite.dir/NNN/testsuite.log, and append them to
11179 testsuite.log instead of re-running the test verbosely.
11181 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11182 file descriptor, write 0 to at_status_file instead of setting
11183 at_status=0, initialize some new variables (at_status_file,
11184 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11185 to rerun the tests, instead append the at_group_log to the
11186 at_suite_log when a test fails.
11187 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11188 with the AS_MESSAGE_LOG_FD redirected to stdout.
11189 (AT_CLEANUP): save the output status in $at_status_file
11190 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11191 its original place.
11192 (AT_CHECK): since tests are run with a redirected stdout,
11193 and used to be re-run in verbose mode, turn some $at_verbose
11194 into echo, and don't redirect the output of testing stdout
11195 and stderr.
11197 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11198 the name of the debugging directory and information about
11199 its contents.
11201 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11203 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
11204 parameter.
11206 2003-05-22 Akim Demaille <akim@epita.fr>
11208 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

11226 Whitespace clean up.
11227 Suggested by Jim Meyering.
11229 2003-05-22 Akim Demaille <akim@epita.fr>
11231 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
11232 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
11233 Reported by Jim Meyering.
11235 2003-05-22 Akim Demaille <akim@epita.fr>
11237 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
11238 Add AC_HELP_STRING to the obsolete macros section.
11239 Typos.
11240 Use '@.' for sentences that ended in a capital letter.

11268 AC_CHECK_HEADERS_NEW): New tests.
11270 2003-05-17 Akim Demaille <akim@epita.fr>
11272 * lib/autoconf/functions.m4: Use the default includes so that
11273 memcmp be declared before being tested.
11274 Reported by Sander Niemeijer.
11275 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
11276 * doc/autoconf.texi (Default Includes): Document

11293 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
11294 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
11295 them uniform, and more robust to Perl special characters.
11296 Reported by Martin Mokrejs.
11298 2003-05-14 Akim Demaille <akim@epita.fr>

11316 and truncate.
11318 2003-05-06 Akim Demaille <akim@epita.fr>
11320 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11321 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11322 by aclocal.m4 is changed it might require the importing of another
11323 m4 extension file, i.e., aclocal must be run.
11325 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11326 (&parse_args): Use --force with aclocal if required and supported.
11327 (&autoreconf_current_directory): Use &run_aclocal.

11334 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
11335 argument instead of a file name, so that the request file remains
11336 open during the whole autom4te run.
11337 ($icache_file): New.
11338 (&freeze): Lock the $icache_file.
11340 2003-04-29 Derek Price <derek@ximbiot.com>
11342 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11343 seperator with m4_append_uniq(). It doesn't work.
11344 (AT_CLEANUP): Add `;' to end of at_help_all.
11345 (AT_INIT): Allow --keywords to be specified more than once. When
11346 grepping $at_help_all for keywords, use the field and keyword
11347 seperators to ensure a complete keyword match. Alter at_prev handling
11348 to support the new --keywords behavior.
11350 2003-04-27 Karl Berry <karl@freefriends.org>
11352 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11353 align better with others. I also made some of the individual
11354 entries on one line, for brevity and to make it easier for me to
11355 sort my dir-example file in the Texinfo distribution :).
11357 2003-04-12 Jim Meyering <jim@meyering.net>
11359 * NEWS: Mention the new macro.

11396 Use them.
11397 * doc/Makefile.am (CLEANFILES): Adjust.
11398 (TEXI2DVI): Make it --batch.
11400 2003-03-31 Derek Price <derek@ximbiot.com>
11402 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
11403 which removed the main loop.
11404 Thanks to Akim Demaille.
11406 2003-03-29 Akim Demaille <akim@epita.fr>
11408 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
11409 that starts a GUI.
11410 From Ilya Zakharevich.
11412 2003-03-29 Akim Demaille <akim@epita.fr>
11414 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
11415 documentation to read is Autoconf's.
11416 Suggested by Paul Eggert.
11418 2003-03-28 Akim Demaille <akim@epita.fr>
11420 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
11421 reading the section "Present But Cannot Be Compiled" when the
11422 header causes problems.
11424 2003-03-28 Akim Demaille <akim@epita.fr>
11426 * tests/torture.at (Configuring subdirectories): Require aclocal
11427 1.4, otherwise the test fails, as it does support configure.ac.
11428 This fixes the "test 40 failed" bug reports.
11430 2003-03-28 Akim Demaille <akim@epita.fr>
11432 * doc/autoconf.texi (C Compiler): `#line' portability.

11461 sense. Verbosify the diversion definitions comment.
11463 2003-03-26 Derek Price <derek@ximbiot.com>
11465 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
11466 AS_PREPARE.

11477 2002/05/09) rejects '#line 32768 "configure"' because the line
11478 number overflows.
11479 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Do not generate
11480 #line directives.
11481 * lib/autoconf/lang.m4 (AC_LANG_SOURCE): Fix comment to match this.

11498 about `$<' in inference rules, it was a bogus interpretation of
11499 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11500 Tru64 make in the "target lookup" section.
11501 (Automake): Automake 1.5+ no longer requires special tools to be
11502 present on the developer's host.
11504 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11506 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

11519 to cope with DOS-style absolute paths, when constructing
11520 ${ac_make}.
11522 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11523 When constructing paths with IFS=:, quote the path. If we're
11524 constructing a DOS-style absolute path, we don't want to split it
11525 on the colon.
11527 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11528 in description.
11530 2003-02-25 Pavel Roskin <proski@gnu.org>
11532 * bin/autoheader.in: Add missing newline when printing
11533 suggestion how change AC_DEFINE call.
11535 2003-02-24 Paul Eggert <eggert@twinsun.com>
11537 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in

11543 to fix a mismatch between example and discussion.
11545 2003-02-24 Kevin Ryde <user42@zip.com.au>
11547 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11548 format starting with "-".
11550 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11552 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11553 is not portable inside Makefile.
11555 2003-02-20 Akim Demaille <akim@epita.fr>
11557 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11558 compiler says yeah, but preproc says nope, compiler is right.
11559 Conversely, prompt the reader to send a bug report to the
11560 maintainers of the package, not of Autoconf.
11562 2003-02-20 Klee Dienes <kdienes@apple.com>
11564 * bin/autoreconf.in (autoreconf_current_directory): Properly

11575 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11576 innocuous variant befor including <limits.h> or <assert.h>. This
11577 works around a bug reported by Albert Chin: HP-UX 11i
11578 (and earlier versions) have a <limits.h> that declares
11579 gettimeofday and many other functions.
11581 2002-12-03 Paul Eggert <eggert@twinsun.com>
11583 Version 2.57.
11585 * NEWS, configure.ac: Update version.
11587 * doc/fdl.texi: Upgrade to FDL version 1.2.
11589 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11590 nontrivially in main's body, so that f's external declaration is
11591 not optimized away in AIX. This should fix the bug reported by
11592 Martin Frydl in
11593 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11595 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11596 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11597 defined, to support freestanding compilers. This should fix the
11598 bug reported by Momchil Velkov in
11599 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11601 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11602 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11605 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11607 * Makefile.maint (www-gnu): New macro.
11608 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11609 the location has moved.
11611 2002-12-02 Martin Frydl <martin@systinet.com>
11613 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11614 \(.*\) match is too long and there is something more to be checked.
11615 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11617 2002-11-15 Akim Demaille <akim@epita.fr>
11619 Version 2.56.
11621 * config/install-sh: chmod +x.
11622 From Paul Eggert.
11623 * config/move-if-change: Indenting changes.
11624 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11625 * configure.ac (AM_INIT_AUTOMAKE): here.
11626 Require 1.7.1.
11628 2002-11-14 Akim Demaille <akim@epita.fr>
11630 Version 2.55.
11632 * config/config.guess, config/config.sub, config/install-sh:
11633 Update from masters.
11635 2002-11-14 Akim Demaille <akim@epita.fr>
11637 * Makefile.maint: Sync with Bison, i.e.:
11638 (po-check): Scan .l and .y files instead of the
11639 .c and the .h files that they generate. This fixes the bug
11640 reported by Tim Van Holder in:
11641 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11642 Look for N_ as well as for _. Try to avoid matching #define for
11643 N_ and _.
11644 From Paul Eggert.
11646 2002-11-14 Akim Demaille <akim@epita.fr>
11648 * doc/autoconf.texi (C Compiler): Compiling several files at once.

11654 From Paul Eggert and Albert Chin-A-Young.
11656 2002-11-14 Kevin Ryde <user42@zip.com.au>
11658 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11659 than assigning in main, to avoid HP cc +O3 optimizing it away.
11661 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11663 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11664 option. Process --recheck after parsing all options. Pass -q
11665 option to configure on --recheck.
11666 (AC_OUTPUT): Pass -q from configure to config.status.
11667 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11668 arguments to record.
11669 * doc/autoconf.texi (config.status Invocation): Document
11670 config.status -q option.
11672 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11674 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11675 Makefile.in if Makefile.am exists.
11676 (output): Strip `.am' from Makefiles. Don't
11677 output AC_CONFIG_FILES if no Makefiles were found.

11688 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11689 declaration in extern "C" too.
11690 Reported by Roberto Bagnara.
11692 2002-11-06 Akim Demaille <akim@epita.fr>
11694 * tests/torture.at (Configuring subdirectories): Don't use grep
11695 -w.

11701 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11702 Remove.
11703 We _have_ to stop using the old compatibility scheme that tried to
11704 avoid useless backslashes because Libtool 1.4.3 contains a
11705 AC_DEFINE([error_t], [int],
11706 [Define to a type to use for \`error_t' if it is not
11707 otherwise available.])
11708 We _have_ to quote the single quote and backslashes with \. The
11709 old compatibility scheme saw that ` was backslashed, and therefore
11710 did not quote the single quote. Hence before this patch, Autoconf
11711 was not compatible with Libtool.
11713 2002-11-04 Paul Eggert <eggert@twinsun.com>
11715 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11720 2002-11-04 Akim Demaille <akim@epita.fr>
11722 Version 2.54c.
11724 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11725 New.
11726 * config/texinfo.tex: Update.
11728 2002-11-03 Akim Demaille <akim@epita.fr>
11730 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11731 from...
11732 (&autoreconf): here.
11733 ($help, $make, &parse_args, &autoreconf_current_directory):
11734 Support -m/--make.
11735 * doc/autoconf.texi (autoreconf Invocation): Adjust.

11743 to ac_cv_func_realloc_0_nonnull.
11744 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
11746 2002-10-31 Akim Demaille <akim@epita.fr>
11748 The test suite was no longer checking for trailing envvars and files.
11750 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
11751 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11753 2002-10-31 Akim Demaille <akim@epita.fr>
11755 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11756 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11757 Make variable, not a shell variable.
11758 Suggested by Bruno Haible.
11760 2002-10-31 Akim Demaille <akim@epita.fr>
11762 * bin/autom4te.in (load_configuration): Reject #args out of any
11763 language.

11779 Suggested by Tim van Holder.
11781 2002-10-29 Paul Eggert <eggert@twinsun.com>
11783 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11784 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11785 Problem reported by Bruno Haible.
11787 2002-10-29 Akim Demaille <akim@epita.fr>
11789 * doc/autoconf.texi (Header Templates): Put also in words what the
11790 pictures says to assist free style readers.
11791 (Customizing autom4te): s/--cache=/--cache /.
11793 2002-10-29 Akim Demaille <akim@epita.fr>
11795 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

11809 * tests/torture.at (Deep Package): New test.

11811 now does it itself.
11813 2002-10-29 Akim Demaille <akim@epita.fr>
11815 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
11816 * doc/autoconf.texi (Invoking autom4te): Rename as...

11827 characters is a back as an `obsolete' warning now.

12043 2002-10-22 Akim Demaille <akim@epita.fr>

12057 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

12062 `@', to tickle Perl's lists.
12063 Reported by Carlos Velasco.

12100 Because of caching, some files that no longer exist and are no
12101 longer required can still cause errors.
12102 Reported by Alexandre Duret-Lutz.
12104 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
12105 to frozen files in @ARGV, as @ARGV must remain being a list of

12108 (&freeze): Use &error.
12109 (&up_to_date): If a file that was included according to the cache
12110 is no longer there, then the output is out dated.

12113 * tests/tools.at (autom4te cache): New.
12115 2002-10-16 Akim Demaille <akim@epita.fr>
12117 * bin/autoconf.as: Kill dead options.
12118 * bin/autoupdate.in (&parse_args): Kill old options.
12119 * bin/autoreconf.in (&parse_args): Remove dead options.
12120 Factor some code.
12121 (&autoreconf): Report the directories we enter *and leave*, so
12122 that error messages can be easily located, and use GNU Make
12123 format, so that Emacs' compile mode understands us.
12124 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12125 if some file was changed instead of `print'.
12126 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
12127 (&parse_args): Remove the dead options.

12140 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

12152 2002-10-11 Akim Demaille <akim@epita.fr>
12154 * tests/torture.at (AC_ARG_VAR): Have configure report the value
12155 of `precious'.
12157 2002-10-11 Akim Demaille <akim@epita.fr>
12159 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12160 file name to enable parallel executions.
12161 From Sam Varshavchik.
12163 2002-10-08 Akim Demaille <akim@epita.fr>
12165 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12166 aclocal invocation, as Gettext macros might not be visible to
12167 aclocal.
12168 Instead of blindly running autopoint, scan configure.ac (not the
12169 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12170 Reported by Paul D. Smith.
12172 2002-10-08 Paul Eggert <eggert@twinsun.com>
12174 Work around problems found when POSIXLY_CORRECT=1 is set.
12175 None of this seems to have anything to do with POSIX, really,
12176 but it's how Perl getopt works.
12177 * bin/autom4te.in (parse_args): Configure GetOpt with
12178 "permute", too.
12179 * doc/autoconf.texi (Invoking autom4te):
12180 --warning -> --warnings.
12181 * lib/autom4te.in: --warning -> --warnings.

12200 2002-09-28 Akim Demaille <akim@epita.fr>
12202 * tests/torture.at (Configuring subdirectories): Be robust to
12203 users who use config.site to require for a cache: in this case,
12204 the two last configure runs, using two different sets of
12205 arguments, trigger a legitimate error.
12207 2002-09-28 Akim Demaille <akim@epita.fr>
12209 * tests/m4sh.at (Functions Support, Functions and return Support):
12210 New.

12217 (autom4te): Specify that the sources are in the $srcdir.
12218 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12220 2002-09-28 Akim Demaille <akim@epita.fr>
12222 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
12223 (tm_zone): Move their rules to...
12224 * lib/autoconf/types.m4: here, using AN_ macros.
12225 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12226 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12227 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

12236 * lib/autoconf/autoconf.m4: Include it.
12237 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12238 that were listed in the original autoscan.list.

12240 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12241 (.m4.m4f): Don't pass --prepend-include, since that's done by
12242 tests/autom4te itself.
12243 * lib/autoscan/Makefile.am: Include freeze.mk.
12244 (autoscan.list): New target --this file is no longer a source.
12245 (autoscan.pre): New file.
12247 2002-09-28 Akim Demaille <akim@epita.fr>
12249 * bin/autoscan.in (@kinds): Make them singular.
12250 Adjust all uses.
12251 (&init_tables): When --debug, report the list of rules to ease
12252 tracking changes in autoscan.list.
12253 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12255 2002-09-28 Akim Demaille <akim@epita.fr>

12261 * bin/autoscan.in (&init_tables): Adjust.
12263 2002-09-28 Akim Demaille <akim@epita.fr>
12265 * lib/autoscan/functions, lib/autoscan/headers,
12266 * lib/autoscan/identifiers, lib/autoscan/makevars,
12267 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12268 `functions' line is now prefixed with `function:'.
12269 * bin/autoscan.in (&init_tables): Adjust.
12271 2002-09-28 Akim Demaille <akim@epita.fr>
12273 From now on, autoscan files must always map a macro name to a
12274 word: there is no `default' macro for autoscan.
12276 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12277 all.
12278 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12279 explicit.
12281 2002-09-28 Akim Demaille <akim@epita.fr>
12283 * bin/autoscan.in (%c_keywords): Remove.

12286 checks.

12369 Suggested by Guido Draheim.
12371 2002-09-13 Akim Demaille <akim@epita.fr>
12373 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12374 (chdir_init) might hang when stat'ing mounted directories.
12375 Reported by Vance Shipley.
12377 2002-09-12 Akim Demaille <akim@epita.fr>
12379 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not

12396 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12397 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case

12418 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12419 `duplicates', since the algorithm was too naive and could keep
12420 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12421 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12422 Reported by Ralf Corsepius.
12423 * tests/torture.at (Configuring subdirectories): Exercise these
12424 cases.

12436 2002-09-06 Akim Demaille <akim@epita.fr>
12438 * doc/autoconf.texi (Setting Output Variables): Clarify what
12439 precious variables are.
12440 Suggested by Pontus Skoeld.
12442 2002-09-05 Akim Demaille <akim@epita.fr>
12444 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12445 (ifnames, autoscan, autom4te): Since we don't only depend on
12446 configure.ac variables (such as VERSION etc.), but also on prefix
12447 and so forth, depend on Makefile, not configure.ac.
12448 Reported by Alexandre Duret-Lutz.
12449 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12451 2002-09-05 Kevin Ryde <user42@zip.com.au>
12453 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12454 doesn't seem to be confined to ia64, just say "some versions".
12456 2002-09-04 Akim Demaille <akim@epita.fr>
12458 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12459 Automake 1.6c.
12460 * Makefile.am (maintainer-clean-local): Remove.
12461 (MAINTAINERCLEANFILES): Remove COPYING.
12463 2002-09-03 Paul Eggert <eggert@twinsun.com>
12465 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12466 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12467 Brinkmann.
12469 2002-09-03 Akim Demaille <akim@epita.fr>
12471 * configure.ac: Bump to 2.53d.
12472 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12473 as of today, on Automake's team suggestion.
12475 2002-09-03 Akim Demaille <akim@epita.fr>
12477 Version 2.53c.
12479 2002-09-02 Akim Demaille <akim@epita.fr>
12481 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12482 SITE_MACRO_DIR.
12483 * configure.ac: Disable SITE_MACRO_DIR.
12485 2002-09-02 Jim Meyering <meyering@lucent.com>
12487 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12488 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12489 Also, tweak grammar: s/make sure to/be sure to/.
12491 2002-09-02 Paul Eggert <eggert@twinsun.com>
12493 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12494 directory names are generally preferable to physical names.
12496 2002-09-02 Akim Demaille <akim@epita.fr>
12498 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12499 Reported by Raja R. Harinath.
12500 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12501 * bin/autoupdate.in: Use error instead of die.
12503 2002-09-01 Paul Eggert <eggert@twinsun.com>
12505 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12506 ordinary shell concatenation rather than echo+tr+sed command that
12507 runs afoul of a long-line-related sed bug in Solaris 8.
12509 * bin/autoheader.in (parse_args): --warning -> --warnings.
12511 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12512 stdout, as traditional "ls" does.
12513 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12514 _AC_COMPILER_EXEEXT_O): Likewise.
12515 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12517 * bin/autoconf.as: Add --prepend-include option. This patch was
12518 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12519 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12521 * bin/autoconf.in, configure: Regenerate.
12523 * doc/autoconf.texi (Special Shell Variables): Mention
12524 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12526 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12527 MAILPATH and set PS1, PS2, PS4 to default values, to work
12528 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12529 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12530 the Autoconf documentation specifies; fall back to "unset" only if
12531 this fails. Use a shell for-loop for this rather than an m4 loop,
12532 to shorten the output script.
12534 2002-08-30 Paul Eggert <eggert@twinsun.com>
12536 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12537 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12538 for the CDPATH problem. Document PWD.
12539 (Limitations of Builtins): Document the problem that "cd $foo" and
12540 "ls $foo" may refer to different directories in shells conforming
12541 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12542 example, since the old example is now out of date.
12544 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12545 FOO" and "ls FOO" talk about different directories; this catches
12546 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12547 spaghetti.
12549 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12550 of rolling our own unset.
12551 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12552 in practice we needn't worry about CDPATH if unset doesn't work.
12554 * Makefile.in, aclocal.m4, bin/Makefile.in,
12555 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12556 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12557 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12558 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12559 tests/Makefile.in: Regenerate with Automake 1.6.3.
12561 * config/config.guess, config/config.sub, config/mkinstalldirs:
12562 Update.
12564 * configure: Regenerate with self.
12566 2002-08-30 Kevin Ryde <user42@zip.com.au>
12568 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12569 default output.
12571 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12573 * bin/autom4te.in (Request::load): Correctly test for "do" read
12574 failure.
12576 2002-08-29 Akim Demaille <akim@epita.fr>
12578 * lib/Autom4te/General.pm (&xqx): New.
12579 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12580 hand, which is not portable.
12581 (&error): New.
12582 * bin/autom4te.in: Use them.
12583 Use &error instead of die.
12584 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12585 Adjust.
12587 2002-08-17 Paul Eggert <eggert@twinsun.com>
12589 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12590 default list of compilers to try, since it was long ago superseded
12591 by the ksh fc builtin. Suggested by Steven G. Johnson.
12593 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12595 * doc/autoconf.texi (Invoking autom4te): End the option table,
12596 fixing a bug introduced by the previous patch.
12597 (Limitations of Make): Add a 'target lookup' subentry in the
12598 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12600 2002-07-29 Mark D. Roth <roth@feep.net>
12602 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12603 options and use $AUTOM4TE_PATH.
12604 * doc/autoconf.texi: Remove documentation of autom4te
12605 --include-envvar and --site-macro-subdir options and document
12606 use of $AUTOM4TE_PATH.
12607 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12608 arguments from each language section.
12610 2002-07-29 Paul Eggert <eggert@twinsun.com>
12612 * doc/install.texi: Include copyright symbol in copyright notice.
12614 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12615 Replace with:
12616 (AM_MAKEINFOFLAGS): New macro.
12617 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12618 * Makefile.am (INSTALL): Use the new macros.
12619 Use -o rather than --output, since "missing" does not grok --output.
12621 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12623 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12624 comments do not always work. Never trust the exit status of
12625 `make -k'.
12627 2002-07-24 Kevin Ryde <user42@zip.com.au>
12629 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12630 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12632 2002-07-23 Paul Eggert <eggert@twinsun.com>
12634 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12635 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12636 apparently treats PATH="nonexistent" as if it contained ".".
12637 Bug reported by Stefan `Sec' Zehl.
12639 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12641 * doc/autoconf.texi (Limitations of Make): Mention the special

12660 Version 2.53b.
12662 2002-07-18 Akim Demaille <akim@epita.fr>
12664 * config/config.guess, config/config.sub: Update.

12798 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12800 * bin/autom4te.in ($cache): Don't define using `$me', the name
12801 of the cache should not depend on the name under which autom4te
12802 was installed.
12804 2002-06-07 Akim Demaille <akim@epita.fr>
12806 * tests/tools.at (autoconf: forbidden tokens, basic)

12895 2002-05-22 Paul Eggert <eggert@twinsun.com>
12897 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12898 from the default list of compilers to try. Suggested by
12899 Kate Hedstrom.
12900 * NEWS: Document the above.
12901 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12903 2002-05-17 Paul Eggert <eggert@twinsun.com>
12905 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12906 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12907 This improves on an earlier suggestion by H. Peter Anvin.
12909 2002-05-16 Paul Eggert <eggert@twinsun.com>
12911 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12912 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12913 Both macros now accept an optional source-dir arg.
12914 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12916 * NEWS: Document this.
12917 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12919 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12920 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12921 not for GNU extensions; this undoes part of the 2000-11-03 change,
12922 reverting to 2.13-compatible behavior.
12923 Add new optional argument DIR.
12924 (AC_FUNC_FNMATCH_GNU): New macro.
12926 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12928 2002-05-08 Paul Eggert <eggert@twinsun.com>
12930 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12931 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12932 and it causes a 'test' syntax error if it fails.
12933 Bug reported by Stephen Gildea.
12935 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12936 If prototypes are supported, use them to check this at compile-time,
12937 instead of trying to check it at run-time. If we must do a run-time
12938 check, assume that setvbuf is standard when cross-compiling, as
12939 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12940 Bug reported by Paul D. Smith.
12942 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12943 argument specifying location of getloadavg.c. This removes a
12944 FIXME. This idea was taken from Jim Meyering's implementation in
12945 textutils.
12946 * doc/autoconf.texi (Particular Functions): Document this.
12947 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12948 that's what the code does; this fixes a bug reported by
12949 Paul D. Smith.
12951 2002-05-03 Akim Demaille <akim@epita.fr>
12953 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12954 autopoint instead of gettextize.
12955 ($uses_alocal): Rename as...
12956 ($uses_aclocal): this.
12957 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12958 Suggested by Bruno Haible.
12960 2002-05-03 Akim Demaille <akim@epita.fr>
12962 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12964 2002-04-29 Paul Eggert <eggert@twinsun.com>
12966 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12967 files to be 1 second older; just set them to be the same time.
12968 Also, sleep 1 second after the first aclocal, to work around
12969 problems with sub-second time stamps on the input files.
12971 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12973 * doc/autoconf.texi: Mention "set -e -x" lossage
12974 under node "Limitations of Builtins".
12976 2002-04-29 Akim Demaille <akim@epita.fr>
12978 * doc/install.texi: Better wording for setting variables when
12979 running configure.
12980 From Christian Cornelssen.
12982 2002-04-29 Akim Demaille <akim@epita.fr>
12984 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12985 of lack of $LINENO support, then the test will compare the $LINENO
12986 in testsuite vs. the lineno in the test file. This is wrong, of
12987 course.
12988 Be sure to protect it.
12989 Reported by Patrick Welche.
12991 2002-04-25 Akim Demaille <akim@epita.fr>
12993 * doc/autoconf.texi (Obsolete Macros): Typo.
12994 Reported by Vladimir Volovich.
12996 2002-04-25 Akim Demaille <akim@epita.fr>
12998 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12999 than some of the input files, hence, on the second run of aclocal,
13000 if some of its input are younger, make them older.
13001 Suggested by Paul Eggert.
13003 2002-04-25 Akim Demaille <akim@epita.fr>
13005 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
13006 Thanks to Paul Eggert.
13008 2002-04-25 Akim Demaille <akim@epita.fr>
13010 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
13011 and ac_subst_vars be sh variables containing the list of
13012 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13013 DEFAULT diversion.
13014 (_AC_INIT_PREPARE): Use them to log them.
13015 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13016 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13017 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13018 _AC_SUBST_FILES and _AC_SUBST_VARS.
13019 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13021 2002-04-24 Akim Demaille <akim@epita.fr>
13023 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13024 autoheader, so that automake does not complain about a missing
13025 config.h.in that was to be created.
13027 2002-04-23 Akim Demaille <akim@epita.fr>
13029 * bin/autoheader.in (parse_args): --warning takes an argument.
13030 Fixes PR/220.
13032 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
13034 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
13035 and bb.out when cleaning up.
13037 2002-04-22 Akim Demaille <akim@epita.fr>
13039 Version 2.53a.
13041 2002-04-22 Akim Demaille <akim@epita.fr>
13043 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
13045 2002-04-22 Akim Demaille <akim@epita.fr>
13047 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
13048 comma.
13049 Reported by Gregory Giannoni.
13051 2002-04-22 Akim Demaille <akim@epita.fr>
13053 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
13054 Fixes false failures on Darwin.
13056 2002-04-21 Paul Eggert <eggert@twinsun.com>
13058 * TODO, bin/autoupdate.in, doc/autoconf.texi,

13060 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
13061 tests/tools.at: Minor spelling and grammar fixes.
13063 2002-04-20 Paul Eggert <eggert@twinsun.com>
13065 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
13066 ZSH_VERSION fixes. Bug reported by Raja R Harinath.

13078 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
13079 Minor spelling and grammar fixes.
13081 * doc/autoconf.texi: Follow the outline suggested in the GNU
13082 Sample Texts sections of the Texinfo 4.2 manual. Most
13083 importantly, this makes sure that the copyright notices appear in
13084 all output formats. You probably need Texinfo 4.2 to generate
13085 the manual now.
13087 Fix some bugs when using "$@" when there might be zero positional
13088 arguments in cases where this matters.
13090 * bin/autoconf.as: Rewrite so that the problem does not come up.

13106 * tests/atgeneral.m4 (AT_INIT): Likewise.
13108 * tests/c.at: We can't have zero arguments, so remove workaround
13109 that is not portable to Zsh.
13111 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
13113 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
13114 from aclocal.m4 too.
13116 2002-04-12 Akim Demaille <akim@epita.fr>

13120 2002-04-10 Akim Demaille <akim@epita.fr>
13122 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
13123 workaround for ${1+"$@"}.
13124 * doc/autoconf.texi (Shell Substitutions): Explain it.
13125 From Oliver Kiddle and Peter Stephenson.
13127 Have M4sh perform minimal shell sanitizing.
13129 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13130 part into...
13131 (_AS_PREPARE): this new macro.
13132 (AS_PREPARE): New.
13133 (AS_INIT): Invoke AS_SHELL_SANITIZE.
13134 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
13136 Adjust Autoconf and Autotest.
13138 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13139 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13140 * lib/autotest/general.m4 (AT_INIT): Likewise.
13141 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
13142 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
13143 AS_SHELL_SANITIZE.
13145 Use this M4sh to generate Autoconf's shell scripts.
13147 * tests/wrapsh.as: New, precursor of wrapsh.in.
13148 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13149 on Autotest and M4sh.
13150 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13151 (wrapsh.in): New target.
13152 * bin/autoconf.as: New, precursor of autoconf.in.
13153 (autoconf.in): New target.
13155 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
13157 * doc/autoconf.texi (Limitations of Make): Mention the issue
13158 with indented comments in rules.
13160 2002-04-09 Andreas Schwab <schwab@suse.de>
13162 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
13163 ac_top_builddir when setting ac_abs_top_builddir.
13165 2002-04-06 Kevin Ryde <user42@zip.com.au>
13167 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
13168 (Portable Shell): Cross reference to Systemology.
13170 2002-04-05 Akim Demaille <akim@epita.fr>
13172 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
13173 directories when descending in a SUBDIRS.
13174 Reported by Ezra Peisach.
13176 2002-04-04 Andreas Schwab <schwab@suse.de>
13178 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13179 contains no literal separators.
13181 2002-04-03 Akim Demaille <akim@epita.fr>
13183 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13184 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13185 Use dnl, not the KILL diversion.
13186 Extracted from...
13187 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13188 (AC_CONFIG_LINKS): here.
13189 Adjust.
13190 Don't use the KILL diversion, as it kills spurious output, which
13191 results in failures being hidden.
13192 Use m4_defn where appropriate.
13193 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13194 after the second argument.
13195 Use m4_defn.
13196 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13197 syntax, as it is provided by M4sugar.
13198 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13200 2002-04-03 Andreas Schwab <schwab@suse.de>
13202 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
13203 expanded if $# <= 2.
13205 * bin/autoreconf.in (autoreconf): Run automake after rerunning
13206 aclocal.
13208 2002-04-03 Akim Demaille <akim@epita.fr>

13211 (_AC_COMPILER_EXEEXT_REJECT): New.
13212 Also recognize *.bb and *.bbg as compilation byproducts.
13213 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
13214 (_AC_COMPILER_OBJEXT): Use them.
13215 Fixes Debian #138666.
13217 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13219 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13221 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13222 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13223 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13224 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13225 (AC_C_CONST): Same.
13226 (AC_C_INLINE): Same.
13227 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
13228 * doc/autoconf.texi, NEWS: Document.
13229 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
13230 AC_C_CROSS.
13232 2002-04-02 Akim Demaille <akim@epita.fr>
13234 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
13235 _AS_MKDIR_P_PREPARE.
13237 2002-03-28 Kevin Ryde <user42@zip.com.au>
13239 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13240 to avoid versions of HP C which don't allow that.
13242 2002-03-27 Paul Eggert <eggert@twinsun.com>
13244 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13245 (AS_SHELL_SANITIZE): Invoke it.
13246 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13248 2002-03-26 Akim Demaille <akim@epita.fr>
13250 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13252 2002-03-26 Akim Demaille <akim@epita.fr>
13254 * doc/autoconf.texi (Introduction): The GNATS base moved.
13256 2002-03-25 Paul Eggert <eggert@twinsun.com>
13258 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13259 as POSIX requires, as it doesn't work with Zsh.
13260 * doc/autoconf.texi (Assignments): Document the problem.
13262 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13264 * doc/autoconf.texi (Limitations of Make): Mention more issue
13265 about VPATH, overriding of macros in sub-makes, and handling of
13266 SHELL.
13268 2002-03-21 Paul Eggert <eggert@twinsun.com>
13270 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13271 problem with here-document buffer boundaries.
13273 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13274 when reinvoking the shell, to work around problems with installers
13275 who put strange things like "cd" commands in their environments.
13277 2002-03-19 Akim Demaille <akim@epita.fr>
13279 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13280 From Aaron Ucko.
13282 2002-03-19 Akim Demaille <akim@epita.fr>
13284 * bin/autoscan.in (scan_file): Specify the location in `&used'
13285 invocations.
13286 From Nicolas Joly.
13288 2002-03-19 Akim Demaille <akim@epita.fr>
13290 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13291 From Nishio Futoshi.
13293 2002-03-19 Akim Demaille <akim@epita.fr>
13295 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13297 2002-03-18 Paul Eggert <eggert@twinsun.com>
13299 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13300 (Limitations of Usual Tools): Add mkdir section.
13302 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13303 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13304 back on AS_DIRNAME to compute prefixes otherwise; this is
13305 roughly what mkinstalldirs does. That way, we need not have
13306 our own filename disassembler. The old disassembler did not
13307 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13309 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13310 Create at_test_all by a series of assignments,
13311 not by a single assignment of a long string. The latter causes ksh
13312 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13313 presumably because of a buffer overrun.
13315 2002-03-14 Paul Eggert <eggert@twinsun.com>
13317 * lib/autotest/general.m4 (at_times_skip):
13318 Renamed from at_times. Now a boolean.
13319 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13320 says 'times: not found'.
13322 2002-03-14 Akim Demaille <akim@epita.fr>
13324 * bin/autoreconf.in (&study_gettextize): New.
13325 (&autoreconf): Handle newest gettextize.
13326 Rerun aclocal if needed.
13327 Suggested by Andreas Schwab.
13329 2002-03-13 Akim Demaille <akim@epita.fr>
13331 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13333 2002-03-13 Akim Demaille <akim@epita.fr>
13335 * doc/autoconf.texi (Header Portability): New.
13336 Add information about stdint.h and inttypes.h from Paul Eggert.
13338 2002-03-13 Akim Demaille <akim@epita.fr>
13340 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13341 -p'.
13342 From Bob Proulx.
13344 2002-03-12 Akim Demaille <akim@epita.fr>
13346 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13347 m4_require.
13349 2002-03-11 Andreas Schwab <schwab@suse.de>
13351 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13352 does not do it if --with-lispdir is given.
13354 2002-03-08 Akim Demaille <akim@epita.fr>
13356 Version 2.53.
13358 2002-03-08 Akim Demaille <akim@epita.fr>
13360 * doc/autoconf.texi (Subdirectories): Clarify that the
13361 subdirectory should exist.
13363 2002-03-08 Akim Demaille <akim@epita.fr>
13365 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13367 2002-03-08 Akim Demaille <akim@epita.fr>
13369 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13370 aliases the actual variables, and modifications of the former
13371 affect the latter.
13373 2002-03-08 Akim Demaille <akim@epita.fr>
13375 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13376 because of C-c: have m4 output in tmp files, then mv them.

13391 Kevin Ryde.
13393 2002-03-05 Akim Demaille <akim@epita.fr>

13406 parallel builds.
13408 2002-03-04 Akim Demaille <akim@epita.fr>
13410 * doc/autoconf.texi (Transforming Names): Equality between target
13411 and host is irrelevant.
13412 (Specifying Names, Canonicalizing): Remove all references to the
13413 backward compatibility hooks. Rather, collect them all into...
13414 (Hosts and Cross-Compilation): this new section.
13415 * doc/install.texi (System Type): Ditto.
13416 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13417 that `--host' implies cross-compilation.
13419 2002-03-04 Akim Demaille <akim@epita.fr>
13421 * doc/autoconf.texi (Evaluation Macros): New.
13422 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13423 useless.
13424 (_m4_foreach): Define the variant with immediate evaluation so
13425 that it contains exactly the items, not an expression which
13426 evaluation is the current item.
13427 (m4_re_string, m4_re_word): Don't over quote them.
13429 2002-03-04 Akim Demaille <akim@epita.fr>
13431 Instead of having stacking `shift's evaluated at the end, let
13432 `foreach' loops immediately evaluate them.
13434 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13435 $*. This is the n-th time I change my mind, but hopefully this is
13436 the last...
13437 (m4_lquote): New.
13438 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13439 efficient.
13440 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13441 it was only a hack for m4_text_wrap.
13442 (m4_car2): Remove, replaced by...
13443 (m4_cdr): New.
13444 (_m4_foreach): Adjust.
13445 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13446 m4_bpatsubst for clarification.
13448 2002-03-04 Akim Demaille <akim@epita.fr>
13450 * doc/autoconf.texi (Changequote is Evil): New.

13482 translate \r\n to \n.
13484 2002-02-07 Akim Demaille <akim@epita.fr>
13486 Version 2.52h.

13498 AC_PREFIX_PROGRAM fails with dashed program names
13500 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13516 2002-02-06 Akim Demaille <akim@epita.fr>

13519 sure not to introduce newlines in at_groups.

13522 2002-02-06 Akim Demaille <akim@epita.fr>
13524 * tests/torture.at (Configuring subdirectories): Skip if aclocal
13525 is not available.

13529 * doc/autoconf.texi (Specific Compiler Characteristics):
13530 Describe HP-UX cc bug workaround more accurately.
13531 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13532 not unsigned long.
13533 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13534 cross-compilers, too. This undoes some of the most recent change
13535 to this file.
13537 2002-02-05 Akim Demaille <akim@epita.fr>
13539 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13540 to make sure they are up to date when `check' is run.

13544 * doc/autoconf.texi (Making testsuite Scripts): Document

13549 * lib/freeze.mk: New.
13551 2002-02-05 Akim Demaille <akim@epita.fr>

13556 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13557 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13559 2002-02-05 Akim Demaille <akim@epita.fr>
13561 * bin/autom4te.in (&parse_args): Implement `frozen files are
13562 optional are the sum of the previous files on the command line'.
13563 Also, pass `--reload-state=' on them, so...
13564 (handle_m4): don't.
13565 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13566 (M4sh): Rely on M4sugar.
13567 (Autotest, M4sh, M4sugar): Use frozen files.
13569 2002-01-31 Akim Demaille <akim@epita.fr>
13571 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

13581 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13582 for plain code, the other for cross-compilation code. The latter
13583 is now run with GCC only.

13586 2002-01-30 Akim Demaille <akim@epita.fr>
13588 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13589 values.

13591 change AC_INIT default values.
13593 2002-01-29 Akim Demaille <akim@epita.fr>

13597 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13599 2002-01-28 Akim Demaille <akim@epita.fr>
13601 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13602 needs an argument.
13604 2002-01-28 Akim Demaille <akim@epita.fr>
13606 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13607 AUTOTEST_PATH *after* it was set.
13608 Don't put `.' in the PATH: the user should be precise and `./' if
13609 needed. In addition, given that the test suite does some `cd', if
13610 `.' is in the path, the `tested programs' sections will report
13611 programs found in the test suite's directory, while during the
13612 tests (performed in their own directory), these programs are no
13613 longer visible. In other words, the results is confusing and
13614 useless.
13615 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13617 2002-01-24 Akim Demaille <akim@epita.fr>

13626 2002-01-24 Akim Demaille <akim@epita.fr>
13628 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13629 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13630 Bourne. Use /bin/sh.
13631 From Andreas Buening.
13633 2002-01-24 Akim Demaille <akim@epita.fr>

13645 Automake.

13649 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13650 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13651 Reported by Geir Ove Myhr.
13653 2002-01-21 Akim Demaille <akim@epita.fr>
13655 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13657 2002-01-21 Akim Demaille <akim@epita.fr>
13659 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13660 message on invalid options.
13661 * bin/autom4te.in (parse_args): Don't use
13662 Autoconf::General::getopt with non valid options.
13664 2002-01-17 Jim Meyering <meyering@lucent.com>
13666 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13667 $ac_cv_exeext so we don't use an old, invalid, cached value.
13669 2002-01-11 Akim Demaille <akim@epita.fr>
13671 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13672 Meyering.

13674 limitation.

13678 2002-01-06 Akim Demaille <akim@epita.fr>
13680 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13681 package.m4, since is really depends upon configure.ac, not
13682 configure.
13683 * doc/autoconf.texi (testsuite Scripts): Adjust.
13684 * tests/Makefile.am (package.m4): New.
13685 EXTRA_DIST it since its a source.
13687 2002-01-06 Akim Demaille <akim@epita.fr>
13689 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13690 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13691 and PACKAGE_BUGREPORT from here...
13692 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13693 arguments.
13694 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13695 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13696 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13697 * tests/tools.at (autoheader): Adjust.

13715 2001-12-17 Jim Meyering <meyering@lucent.com>
13717 * doc/autoconf.texi (New Macros): Tweak wording.
13719 2001-12-14 Akim Demaille <akim@epita.fr>
13721 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13722 trailing files, don't apply `-rf' to files which might not be
13723 created by configure (core, core.*, and *.core), but just `rm -f'.
13724 Suggested by Jonathan Kamens.
13726 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13728 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

13755 2001-11-26 Akim Demaille <akim@epita.fr>

13758 Map to 1 in order to simplify its uses.
13760 2001-11-26 Akim Demaille <akim@epita.fr>
13762 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13763 Remove $filepath, useless.
13764 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13765 variables, they are really part of the tokens.
13766 Split the input line on spaces and then look for tokens.
13767 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13768 because of `lex$U.$(OBJEXT)'.
13769 (&scan_files): Use "@list" instead of join.
13770 * doc/Makefile.am (CLEANFILES): Add *.fns.
13772 2001-11-26 Akim Demaille <akim@epita.fr>
13774 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13775 Remove, replaced by...
13776 * tests/wrappl.in: Be common for all the Perl executables.
13777 In particular autoscan and autoheader want -I.
13778 * configure.ac: Adjust.

13808 Test groups are now run two directories deeper.
13810 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,

13814 top_srcdir, builddir and top_builddir.

13816 suite, use `*dir' when relatively to the current group dir.
13818 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13820 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13821 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13822 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13823 spelling errors.
13825 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13827 * doc/autoconf.texi (Using System Type): Add an example of `case
13828 $host' usage so people quit using `case $target' everywhere.
13830 2001-11-22 Akim Demaille <akim@epita.fr>
13832 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13833 spotted by Jim Meyering.
13835 2001-11-16 Paul Eggert <eggert@twinsun.com>
13837 This patch implements a `long double' suggestion by Oliver Kiddle.
13839 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13840 static, to catch errors if the value isn't known at compile-time
13841 and the compiler supports dynamic arrays. Change its name from
13842 `_array_' to `test_array' to avoid potential name clashes.
13843 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13844 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13845 better than double. Catch a bug in GCC 2.95.2 x86.
13846 * doc/autoconf.texi (C Compiler): Document the above.
13847 * NEWS: Likewise.
13849 2001-11-13 Akim Demaille <akim@epita.fr>
13851 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13852 hand.
13853 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13855 2001-11-13 Akim Demaille <akim@epita.fr>
13857 * lib/autotest/general.m4 (AT_INIT): After having run the test
13858 group, go back to the initial directory, not to at_suite_dir.
13860 2001-11-13 Akim Demaille <akim@epita.fr>
13862 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13863 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13864 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13865 option.
13866 (AT_CHECK_CONFIGURE): Use absolute paths.
13867 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13868 The problem is still the old one: there is no means in M4 (that I
13869 know about) to create a defining macro, because there is no means
13870 to create `$1' etc., therefore, the defining macro ``swallows''
13871 all the arguments meant to the defined macro.
13873 2001-11-13 Akim Demaille <akim@epita.fr>
13875 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13876 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13877 configure.ac.
13878 * tests/aclocal.m4: Remove, as it is no longer used.
13880 2001-11-13 Akim Demaille <akim@epita.fr>
13882 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13883 variable names when referring to a single test group, or to
13884 `suite' when referring to the whole test suite.
13885 `at_last_test' is removed: m4 compute at_format itself.
13886 (at_stdout, at_stder1, at_stderr): New variables.
13887 (AT_CHECK): Use them.
13889 2001-11-13 Akim Demaille <akim@epita.fr>
13891 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13892 in PATH.
13893 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13894 Do it as soon as a test fails, don't wait till the end of the test
13895 suite.
13896 Don't remove $as_me.[0-9]*, since these files no longer exist.
13898 2001-11-13 Akim Demaille <akim@epita.fr>
13900 * tests/tools.at: Use absolute paths, since we are no longer run
13901 in place.
13903 2001-11-13 Akim Demaille <akim@epita.fr>
13905 Now that tests are running in their own private dir, there is no
13906 need to list the files to remove at the end of tests groups.
13908 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13909 (AT_data_files, at_data_files): Remove.
13910 (AT_CLEANUP, AT_DATA): Simplify.
13911 (AT_INIT): Adjust.
13912 Remove the group dir if !debug && !failed.
13913 * tests/atspecific.m4: Adjust.
13915 2001-11-13 Akim Demaille <akim@epita.fr>
13917 Start a new layout for Autotest: `testsuite' creates
13918 `testsuite.dir' in which the at-check-line etc. files are to be
13919 found, and `testsuite.dir/003' where the test group 3 is run.
13921 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13922 at_check_line_file, at_format, at_test_normalized, at_group_dir
13923 are new variables.
13924 Create the directories.
13925 Use absolute paths for at- files.
13926 (AT_CHECK): Adjust.
13928 2001-11-11 Michael Matz <matz@kde.org>
13930 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13931 (m4_car2): New.
13932 (m4_car): Properly quote arguments.
13934 2001-11-13 Akim Demaille <akim@epita.fr>
13936 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13937 with stricter rules on LIBOBJS.
13939 2001-11-12 Paul Eggert <eggert@twinsun.com>
13941 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13942 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13943 __PROTOTYPES too.
13945 2001-11-12 Akim Demaille <akim@epita.fr>
13947 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13949 2001-11-12 Akim Demaille <akim@epita.fr>
13951 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13952 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13953 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13954 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13955 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13956 specify to what the macro should be defined (typically to 1).
13958 2001-11-12 Akim Demaille <akim@epita.fr>
13960 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13961 From Jim Meyering.
13963 2001-11-12 Akim Demaille <akim@epita.fr>
13965 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13966 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13967 definition used by Automake where LEX is +/- "${missing} lex" and
13968 `missing' itself contains variables.
13970 2001-11-12 Akim Demaille <akim@epita.fr>
13972 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13973 Now that M4sh pushes BODY, the comments were output at the end of
13974 the test suites.
13976 2001-11-08 Akim Demaille <akim@epita.fr>
13978 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13979 that we can trace macros from aclocal.m4.
13980 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13981 obsoleted, and redirect to the former anyway.
13982 Reported by Ralf Corsepius.
13984 2001-11-08 Akim Demaille <akim@epita.fr>
13986 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13987 processed only if present.
13988 * tests/torture.at (Configuring subdirectories): Use autoreconf
13989 instead of successive calls to autoconf.
13990 Add a nonexistent subdirectory to exercise the patch above.
13991 Reported by Ralf Corsepius.
13993 2001-11-08 Kevin Ryde <user42@zip.com.au>
13995 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13996 doesn't accept .S files.
13998 2001-11-07 Akim Demaille <akim@epita.fr>
14000 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14001 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14002 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14003 * bin/autom4te.in (warn_forbidden): New.
14004 (handle_output): Use it.
14005 Read m4_pattern_forbid with messages.
14007 2001-11-05 Akim Demaille <akim@epita.fr>
14009 * bin/autom4te.in (--normalize): Remove.
14010 * lib/autom4te.in: Adjust.
14012 2001-11-05 Akim Demaille <akim@epita.fr>
14014 * tests/Makefile.am (testsuite): Rename this target as...
14015 ($(TESTSUITE)): this.
14016 From Nicolas Joly.
14018 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14020 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14021 the --prefix option, also remove it's argument.
14023 2001-11-05 Akim Demaille <akim@epita.fr>
14025 * doc/autoconf.texi (testsuite Invocation): Update.
14026 (Writing testsuite.at): Update.
14028 2001-11-03 Akim Demaille <akim@epita.fr>
14030 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14032 2001-11-03 Akim Demaille <akim@epita.fr>
14034 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14035 (&file_name_is_absolute): New, wrappers around routines from
14036 File::Spec.
14037 Use and export them.
14038 (&find_configure_ac): Optionally take a directory where to look at.
14039 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14040 the arguments.
14041 Default @ARGV to `.', not find_configure_ac.
14042 (&autoreconf): Argument is a directory.
14043 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14044 * doc/autoconf.texi (autoreconf Invocation): Update.
14046 2001-11-03 Akim Demaille <akim@epita.fr>
14048 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14049 (@export_forward_subs): New.
14050 Add basename, dirname, and fileparse.
14051 (@EXPORT): Adjust.
14052 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14053 Don't look for aclocal flags if we already know aclocal is not
14054 used.
14055 Move aclocal.m4t only if it exists.
14056 Reported by Ezra Peisach.
14058 2001-11-03 Akim Demaille <akim@epita.fr>
14060 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14061 passed on command line, defaulting to ./configure.ac if present.
14062 (&maybe_autoreconf, File::Find): Remove, unused.
14063 (&autoreconf): If autoconf is not used, don't try to trace.
14065 2001-11-02 Akim Demaille <akim@epita.fr>
14067 * configure.ac: Bump to 2.52g.
14069 2001-11-02 Akim Demaille <akim@epita.fr>
14071 Version 2.52f.
14073 2001-11-02 Akim Demaille <akim@epita.fr>
14075 * config/config.guess, config/config.sub, doc/standards.texi:
14076 * config/lispdir.m4: Update from masters.
14077 * configure.ac: Bump to 2.52f.
14079 2001-11-02 Akim Demaille <akim@epita.fr>
14081 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14082 Don't run aclocal when aclocal.m4 is not from aclocal.
14083 From Ezra Peisach.
14084 Don't run libtoolize and gettextize if --install is not given.
14086 2001-11-01 Paul Eggert <eggert@twinsun.com>
14088 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14089 be invoked before _AS_LINENO_PREPARE.
14090 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14091 than character ranges.
14093 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14094 invoking AS_BASENAME. Set the locale variables to 'C' if
14095 possible, as POSIX requires this to get the traditional
14096 behavior.
14097 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14099 2001-10-31 Paul Eggert <eggert@twinsun.com>
14101 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14102 with {}, as that triggers a bug in Bash 2.05.
14104 (_AS_LINENO_PREPARE): Use Sed rather than
14105 Awk. Fix the sed prepass to work even if there are multiple
14106 instances of $LINENO on the same line. Do not substitute for
14107 other variables like $LINENOT. Do not check file dates; such a
14108 check is unreliable on sufficiently fast machines, and removing
14109 the check makes the code simpler and more reliable. Check for
14110 output and chmod failures.
14112 * doc/autoconf.texi (Special Shell Variables): Document
14113 the above.
14115 2001-10-31 Akim Demaille <akim@epita.fr>
14117 * tests/Makefile.am (atconfig): Remove this target, Automake
14118 handles it now.
14120 2001-10-31 Akim Demaille <akim@epita.fr>
14122 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14123 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14124 provided, while it is optional.
14125 * configure.ac: Adjust.
14127 2001-10-26 Paul Eggert <eggert@twinsun.com>
14129 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14130 lib/Autom4te/Struct.pm:
14131 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14132 with 5.005_02.
14134 * doc/autoconf.texi (Special Shell Variables): Document some
14135 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14137 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14138 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14139 eval $LINENO is not portable in practice.
14141 2001-10-24 Akim Demaille <akim@epita.fr>
14143 * lib/Autom4te/General.pm (backname): New.
14145 2001-10-24 Akim Demaille <akim@epita.fr>
14147 * m4/: Remove, merged into...
14148 * config/: here.
14150 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14152 * doc/autoconf.texi (Shellology): Mention the problems with bash
14153 2.05's use of ANSI quoting in its `set' builtin.
14155 2001-10-22 Paul Eggert <eggert@twinsun.com>
14157 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14158 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14159 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14160 POSIX decided to standardize on the int flavor of strerror_r.
14161 Always do char* test, as there's no reason not to.
14162 Assign to a char* var, to catch strerror_r that returns int*.
14164 * doc/autoconf.texi (Particular Functions):
14165 Document the above changes. Also, document the fact that
14166 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14168 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14170 2001-10-20 Akim Demaille <akim@epita.fr>
14172 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14173 the executable was missing from the log.

14177 * lib/Autom4te/General.pm (&update_file): If destination is
14178 unchanged, remove the source.
14179 (&up_to_date_p): Don't be verbose, be debug.
14180 * bin/autoreconf.in: No longer support --m4dir.
14181 (&autoreconf): Display the full path of the configure.ac we are
14182 studying.
14183 Trace it only once.
14184 Be sure to honor --force with gettextize.
14185 Always run aclocal.
14186 * doc/autoconf.texi: Adjust.
14188 2001-10-20 Akim Demaille <akim@epita.fr>
14190 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14191 Remove, dead.
14192 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14193 `intl' is already present, as it refuses unless --force.
14194 (&parse_args): Use -I, --include instead of the old Autoconf
14195 options.
14196 ($localdir, $autoconf_dir): Remove.
14197 (@include): New.
14198 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14200 2001-10-19 Jens Petersen <petersen@redhat.com>
14202 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

14207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
14208 file in @configure_input@.
14209 Don't mention `automatically' in addition to `generated'.
14210 * tests/torture.at (#define header templates): Adjust.
14212 2001-10-19 Akim Demaille <akim@epita.fr>
14214 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14215 comment, explain how to install automatic mode selection.
14216 From Russ Allbery.
14218 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14220 * bin/autoreconf.in (autoreconf): Display the path to the
14221 configure.ac being studied.
14223 2001-10-18 Paul Eggert <eggert@twinsun.com>
14225 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14226 long, to work around a bug in the HP C compiler version HP92453-01
14227 B.11.11.23709.GP.
14229 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14230 (AS_BASENAME_EXPR): New macro.
14231 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14232 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14233 and fall back on 'sed' only if the other two fail. This makes
14234 AS_BASENAME act more like AS_DIRNAME.
14235 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14236 contains white space.
14237 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14238 Use AS_DIRNAME, since I think it's now DOS-friendly.
14239 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14240 Allow "dirname //FOO" to return either / or //, as POSIX allows
14241 either behavior.
14243 2001-10-10 Akim Demaille <akim@epita.fr>
14245 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
14246 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
14247 From Eric Sharkey.
14249 2001-10-10 Akim Demaille <akim@epita.fr>
14251 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14252 m4_define, since...

14267 transition code.
14269 2001-10-08 Akim Demaille <akim@epita.fr>
14271 * bin/autoreconf.in (&autoreconf): Remove debugging code.
14272 (&parse_args): Pass verbosity/debugging options to subtools when
14273 --debug, not when --verbose.
14274 * lib/autom4te.in (Autoreconf-preselections): New.
14275 (Autoconf): Use it.
14277 2001-10-08 Akim Demaille <akim@epita.fr>

14281 2001-10-08 Akim Demaille <akim@epita.fr>
14283 * doc/autoconf.texi (autoreconf Invocation): Adjust.

14291 bother with $force since...
14292 * lib/Autom4te/General.pm: does.
14294 2001-10-08 Akim Demaille <akim@epita.fr>
14296 * bin/autoreconf.in: Rewrite in Perl.
14297 * configure.ac: Adjust.

14383 ourselves with CONFIG_SHELL.
14385 2001-10-05 Paul Eggert <eggert@twinsun.com>
14387 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
14388 doesn't exist. Remove *.tmp, as a .tmp file is created during the
14389 build of $(TESTSUITE).

14472 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

14504 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
14505 (AC_PROG_CPP requires AC_PROG_CC): here and...
14506 * tests/fortran.at (GNU Fortran 77): there.
14507 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14508 AC_TRY_RUN is about compilation, not shell commands.

14511 2001-09-27 Akim Demaille <akim@epita.fr>
14513 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
14514 Raja R Harinath:
14515 Be sure to detect when $LINENO always returns the same value.
14516 Look for the original script, basename($0) is certainly not
14517 enough.
14518 Pass the CLI arguments to `$as_me.lineno'.

14539 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
14540 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
14541 builddir, buildpath, top_builddir, and top_buildpath.
14542 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
14543 the current directory.

14568 * doc/autoconf.texi (Common Shell Constructs): Rename as...

14615 2001-09-22 Akim Demaille <akim@epita.fr>

14620 `$LINENO' support replacement when not supported.
14621 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14622 them explicitly to be sure they are not output before this section

14632 character (u: -> ue) in a code comment.
14633 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know

14660 * lib/autotest/general.m4: Replace occurrences of ':' in
14661 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14663 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14668 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14670 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

14682 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14684 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14685 already have $file). Set output files to binary mode (helps avoid
14686 CR issues on DOSish systems).
14688 2001-09-19 Akim Demaille <akim@epita.fr>
14690 * lib/autotest/general.m4: Englishoes.
14691 From Tim Van Holder and Alexey Mahotkin.
14693 2001-09-18 Paul Eggert <eggert@twinsun.com>
14695 * doc/autoconf.texi (Common Shell Constructs): New node,
14696 documenting AS_DIRNAME.
14697 (Limitations of Usual Tools): Refer to it when discussing dirname.
14698 Also, update discussion of POSIX standard to reflect latest draft.
14700 * lib/autoconf/c.m4:
14701 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14703 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14704 Do not pass a first argument with leading '-'
14705 to expr, by parenthesizing initial integers that might be negative.
14707 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14708 now merely checks whether it is an error to pass an argument
14709 to getpgrp.
14711 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14712 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14713 whether it is a (compile-time) error to pass an argument to
14714 getpgrp. This simpler test supports the revised documentation,
14715 and is all that AC_FUNC_GETPGRP's users really need.
14717 2001-09-18 Akim Demaille <akim@epita.fr>

14730 correctly.
14731 Add test for AS_BASENAME.
14732 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14733 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14734 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14735 * tests/base.at: Fixed the expected responses. The old ones were
14736 one line out...
14737 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14738 the documentation claims it should (and how it behaved in 2.13).
14740 2001-09-18 Akim Demaille <akim@epita.fr>
14742 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

14751 Use `m4_PACKAGE_STRING'.
14752 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14753 the only optional argument is the name of the test suite.
14754 Expect `package.m4' to define the package signature.
14755 * lib/autom4te.in (Autotest): Add `package.m4?'.
14756 * tests/Makefile.am (package.m4): New.
14757 * tests/suite.at: ifnames is a victim.
14759 2001-09-18 Akim Demaille <akim@epita.fr>
14761 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,

14776 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14777 Always include <stdio.h> and <stdlib.h>. Evaluate
14778 the expression in an extra function before these includes. Call
14779 fprintf "%d" only after ensuring the argument is of type 'int'.

14784 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14785 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14786 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14787 when they don't exist.
14789 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14790 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14791 need it.
14793 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14794 version with the version used by fileutils 4.1, except use
14795 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14796 we don't need it.
14798 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14800 2001-09-13 Akim Demaille <akim@epita.fr>

14840 * lib/autotest/general.m4 (AT_INIT): Create and remove
14841 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

14952 2001-09-05 Akim Demaille <akim@epita.fr>
14954 Be ready to handle filenames as stupid as `dnl.at', for if even
14955 the maintainer is dumb enough to do that...
14957 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14958 excellence in M4 quotation: consider `__file__' is active.
14960 And BTW, when invoking m4, pass the --include in the right order:
14961 the wrong one.
14963 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14964 4m.

14988 CVS GNU M4 doesn't like `undefine(undefined)'.
14990 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14991 New, extracted from main.
14992 Use IO::File wherever possible.
14993 (input.m4): Be constant, use -I instead of hard coding $tmp.
14994 Therefore be a quoted heredoc.
14995 Don't invoke `_au_disable', since ac was not loaded, but just
14996 `unm4.m4'.
14998 2001-08-31 Akim Demaille <akim@epita.fr>
15000 Version 2.52d.

15023 2001-08-31 Akim Demaille <akim@epita.fr>
15025 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
15026 (testsuite Scripts): There is no such thing as `atconfig.in'.
15027 And actually one diagram is missing: test suite runtime.
15029 2001-08-31 Akim Demaille <akim@epita.fr>
15031 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
15032 inverse order.
15034 2001-08-31 Akim Demaille <akim@epita.fr>
15036 * bin/autoupdate.in (@include): `installcheck' revealed the path
15037 to m4sugar was lacking!
15039 2001-08-31 Akim Demaille <akim@epita.fr>
15041 * man/Makefile.am (.x.1): We really have to pass
15042 autom4te_perllibdir.
15044 2001-08-31 Akim Demaille <akim@epita.fr>
15046 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

15048 run is stupid.
15050 2001-08-31 Akim Demaille <akim@epita.fr>
15052 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
15053 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15054 Use directly autom4te, not autoconf.

15071 Promote --include over --macrodir and other obsolete options.
15073 2001-08-31 Akim Demaille <akim@epita.fr>
15075 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

15079 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
15080 (autoheader): Pass --force since the test suite goes too fast for
15081 the time stamps.
15082 Adjust to the new autoheader messages.
15084 2001-08-31 Akim Demaille <akim@epita.fr>
15086 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

15096 Drop AC_MACRODIR dead for real.
15097 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15098 `autoheader: `config.hin' is created'.
15099 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15101 2001-08-31 Akim Demaille <akim@epita.fr>
15103 * bin/autoheader.in: Rewrite in Perl.

15106 2001-08-31 Akim Demaille <akim@epita.fr>

15109 Map --localdir, --autoconf-dir onto it.
15110 Forward autom4te's options instead of interpreting them.
15111 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15112 There is no such envvar since the inception of autom4te.cfg.
15113 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15114 * bin/autoupdate.in: Adjust, and perform more control.
15115 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.

15118 2001-08-31 Akim Demaille <akim@epita.fr>
15120 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15121 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15122 optionally `FILE'.
15123 Use -e, not -f, since /dev/null for instance is OK.
15124 (&parse_args): Adjust.
15125 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15127 2001-08-31 Akim Demaille <akim@epita.fr>
15129 * configure.ac: Also find tested executables in bin.
15130 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
15131 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
15132 installed peer executables, only PATH is allowed to resolve it.
15133 Pass `autoconf_dir' via options, not via invisible envvars.
15134 * lib/Autom4te/General.pm (&find_peer): Remove.
15135 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15136 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15137 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15138 find the executables for it.
15139 * tests/Makefile.am: Major cleanup. Too lazy to document...
15140 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15141 We only need PERL.
15142 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15143 indeed related to running the test suite, while passing
15144 --autoconf-dir and others is related to running non installed
15145 Autoconf executables. So don't do that, leave it to...
15146 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15147 * tests/autoscan: New.
15148 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15149 refer to library files: rely on --language.
15151 2001-08-29 Akim Demaille <akim@epita.fr>
15153 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

15156 2001-08-29 Akim Demaille <akim@epita.fr>
15158 * doc/autoconf.texi: Strip the @nodes.
15159 Suggested by Paul Eggert.

15162 2001-08-29 Akim Demaille <akim@epita.fr>
15164 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15165 Suggested by Paul Eggert.
15167 2001-08-29 Akim Demaille <akim@epita.fr>
15169 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15170 download in a tmp dir.
15172 2001-08-29 Akim Demaille <akim@epita.fr>
15174 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

15186 * bin/autoconf.in: Simplify and adjust.
15187 * tests/Makefile.am (AUTOMAKE): Use --set.
15188 * tests/atlocal.in: Adjust.
15189 * BUGS: distcheck and check are weak.
15191 2001-08-29 Akim Demaille <akim@epita.fr>
15193 * lib/autotest/general.m4: Use
15194 foo=`(command) 2>/dev/null`
15195 not
15196 foo=`command` 2>/dev/null
15197 (at-devnull): Rename as...
15198 (AT-devnull): this.
15199 (--clean): Remove AT-* files too.
15200 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15201 Reported by Nicolas Joly.

15211 * doc/autoconf.texi (Function Portability): Mention C right shifts.
15213 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
15215 * lib/autotest/general.m4: Reword some messages.
15216 (AT_INIT): Check for the `times' builtin before using it.

15716 documentation for AC_C_BIGENDIAN.
15718 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15720 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15721 magic values from an object file when cross-compiling.
15722 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15724 2001-08-10 Akim Demaille <akim@epita.fr>
15726 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15727 effects.
15728 Suggested by Russ Allbery.
15730 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15732 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15733 current $prefix to the sub-configures.
15735 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15737 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15738 extension (needed on BeOS). Reported by Guido van Rossum.
15740 2001-08-09 Akim Demaille <akim@epita.fr>
15742 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15744 2001-08-07 Akim Demaille <akim@epita.fr>
15746 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15747 removed.
15748 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15749 No need to remove the files before and after the each test, before
15750 each test and at the end of the suite is enough.
15751 Display only the children `times', not the shell's.
15752 If the test failed or was skipped, at-times is not available.
15754 2001-08-07 Akim Demaille <akim@epita.fr>
15756 Always produce testsuite.log, including when there are no
15757 failures. This helps getting information on skipped tests, and
15758 duration of the tests. Err, implement the latter btw.
15760 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15761 Dump information on the first run of each test.
15762 (AT_CLEANUP): Create `at-times' containing the duration of the
15763 test group.
15765 2001-08-07 Akim Demaille <akim@epita.fr>
15767 The use of `dumpstat' revealed that `len' was used although it
15768 should not. m4_text_wrap was using it, but in the Autoconf world
15769 where it is legal. Hence (i) test M4sh in its own world, not
15770 Autoconf's, and (ii), ahem, fix the bug :)
15772 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15773 does not like `' instead of [].
15774 (AT_INIT): Forbid `^_?AT_'.
15775 And don't output such tokens.
15776 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15777 `script.as', and `autom4te.cache'.
15778 Remove `empty' and `macro' which are no longer used.
15779 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15780 * tests/m4sugar.at: Use it.
15781 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15783 2001-08-07 Akim Demaille <akim@epita.fr>
15785 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15787 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15789 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15791 2001-08-04 Akim Demaille <akim@epita.fr>
15793 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15794 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15795 AC_TRY_LINK.
15796 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15797 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15798 (AC_F77_MAIN): Likewise.
15800 2001-08-04 Akim Demaille <akim@epita.fr>
15802 Don't rely on M4sugar outputting the patterns in files, since we
15803 might process the output _without_ running m4, hence without these
15804 files.
15806 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15807 * bin/autom4te.in (@Request::includes): Remove, unused.
15808 (@Request::source): Rename as...
15809 (@Request::input): this.
15810 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15811 (&handle_output): Fetch the patterns from the traces.
15812 `$forbidden' and `$allowed' are constant: use m//o.
15813 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15814 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15816 2001-08-04 Akim Demaille <akim@epita.fr>
15818 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15819 autoconf', i.e., in addition to caching traces, cache the output.
15821 * bin/autom4te.in (Request::cache): Rename as...
15822 (Request::id): this.
15823 ($cache, $icache, $tcache, $ocache): New.
15824 (&handle_m4): Save M4 output in the cache instead of $tmp.
15825 (&handle_output): Adjust.
15826 (&up_to_date_p): Check that the output cache is up to date too.
15827 (top level): Run `&handle_m4' iff force or the cache is invalid.
15828 Run `&handle_output' if the output cache is more recent.
15830 2001-08-04 Akim Demaille <akim@epita.fr>
15832 * bin/autom4te.in ($force): New.
15833 (&parse_args, &print_usage): -f, --force is a new option.
15834 (&handle_output): CPP directives might have spaces after `#'.
15835 (&parse_args): The first file only can be frozen.
15837 2001-08-04 Akim Demaille <akim@epita.fr>
15839 Don't let autom4te compute the `include' traces several times:
15840 first check that the trace cache file is up to date, and then
15841 compare its timestamp with that of the output.
15843 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15844 the preamble. Don't require 5.005 as Autom4te::General does it,
15845 and better yet (use `use', not `require'!).
15846 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15847 Class::Struct as Autom4te::Struct.
15848 * lib/Autom4te/General.pm (File::stat): Use it.
15849 (&mtime): New, export it.
15850 * bin/autom4te.in: Use it.
15851 Declare `$req' is invalid if it is outdated.
15852 Don't declare it valid before saving it if something went wrong.
15854 2001-08-04 Akim Demaille <akim@epita.fr>
15856 Autom4te shall not encode Autoconf data, and preselecting traces
15857 must be proposed to the users.
15859 * bin/autom4te.in (@required_trace): Remove.
15860 (@preselect): New.
15861 (&parse_args, &print_usage): -p, --preselect is a new option.
15862 (&up_to_date_p): Adjust.
15863 * bin/autoconf.in: Preselect some Autoconf macros.
15865 2001-08-04 Akim Demaille <akim@epita.fr>
15867 * tests/tools.at (autoconf --trace: user macros): Check traces on
15868 macros invoked without arguments, and macros invoked with multiple
15869 lines arguments.
15871 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15873 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15874 arguments.
15876 2001-08-03 Akim Demaille <akim@epita.fr>
15878 * bin/autoconf.in ($@): Work around the usual sh bug.
15879 From Nicolas Joly.
15881 2001-08-03 Akim Demaille <akim@epita.fr>
15883 Clean up the handling of the M4 builtins tracing exception.
15885 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15886 trace requests.
15887 (@m4_builtins): Rename as...
15888 (@m4_builtin): this.
15889 (%m4_builtin_alternate_name): New.
15890 (&parse_args): Complete the trace requests with alternate names.
15891 (&handle_traces): Hence no longer do it here.
15892 (&trace_requests): Remove, unused.
15894 2001-08-03 Akim Demaille <akim@epita.fr>
15896 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15897 m4_if, and m4_wrap.
15899 2001-08-03 Akim Demaille <akim@epita.fr>
15901 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15902 (m4_divert_pop): Dump the whole diversion stack when a diversion
15903 mismatch happens.
15904 * bin/autom4te.in (&handle_output): Remember of the first
15905 occurrence of a possibly undefined macro, not the last.
15906 Complain about the possibly undefined macros in the same order as
15907 the appear in the output.
15908 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15909 * tests/tools.at (autoconf: forbidden tokens, basic)
15910 (autoconf: forbidden tokens, exceptions): No longer sort
15911 autoconf's stderr, as it is now deterministic.
15912 Check that `dnl' is caught.
15914 2001-08-01 Akim Demaille <akim@epita.fr>
15916 * configure.ac: Bump to 2.52c.

15928 2001-08-01 Akim Demaille <akim@epita.fr>

15931 `die'.
15932 (&END): New.
15933 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
15934 `END', as `Autom4te::General::END' will be triggered.
15935 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15936 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

16371 cross-language link tests can be performed successfully.
16372 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
16373 after $LIBS, for consistency; this should be the general rule since

16494 Automake), include the separator themselves.
16496 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
