1224 Cover more potentially problemtic file names. Use the new
1227 Properly handle funny file names for headers in config.status.
1228 The test suite did not cover this bug because the code was not
1229 quoting properly the arguments of `rm -f' (which "fails" silently)
1230 as well as the arguments of `diff' (whose output was redirected to
1231 /dev/null so we couldn't see its error message).

1349 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1351 <DEFAULTS>: Delay computation of variables based on $at_dir...
1352 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.

1371 * doc/autoconf.texi (Particular Programs): Do not mention the
1372 Autoconf version in which the AC_PROG_INSTALL change was done.
1373 Suggested by Paul Eggert.

1377 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1378 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1379 mode, we change to the source directory, also set $ac_pwd so we
1380 do not go back to the build tree for the next config subdir.
1381 * tests/torture.at (Deep Package): Extend test to contain two
1382 config subdirs on the top level.
1384 Fix parallel `maintainer-check'.
1385 * Makefile.am (maintainer-check-tests): Depend on `all'.
1386 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

1413 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1415 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1416 check_SCRIPTS. Building the wrappers for `all' allows help2man

1436 (m4_require): Use m4_do, not m4_join.
1438 Fix some whitespace tests on cygwin.

1448 (m4_require): Avoid extra macro calls.

1452 * tests/torture.at (srcdir): Fix quoting.

1458 * tests/base.at (Input/Output): Likewise.
1459 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1460 config.guess, and config.sub to test source tree.

1462 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1463 * tests/torture.at (Substitute a 2000-byte string): Drop
1464 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1465 (Substitute a newline, datarootdir workaround): Likewise.
1466 (Define a newline): Adjust for linenumber changes in configure.ac.
1467 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1474 * tests/tools.at (Syntax of the shell scripts): Likewise.
1476 * tests/m4sh.at (LINENO): Quote $0.
1478 Fix testsuite program wrapper for whitespace in `pwd`.
1479 The problem here is that the usual mantra is that command
1480 variables can contain arguments, thus we cannot just escape
1481 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1482 $top_builddir/tests directory early in $PATH, so that the
1483 wrappers are found by their plain name.
1484 * tests/wrapper.as: Put $testdir early in $PATH.
1485 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

1497 <at_func_create_debugging_script, Driver Loop>:
1498 Quote $at_group_dir.
1499 * tests/autotest.at (whitespace in absolute testdir): New test.
1501 * lib/autom4te.in: Quote @datadir@.
1503 Proper file name escaping in Autoconf programs and Perl modules.
1504 This includes escaping of characters special to the shell
1505 as well as special to Perl, e.g., leading `<' or `>'.
1506 For example, when $file starts with `>', `open ">$file"'
1507 wrongly tries to append to a different file.
1508 * bin/autoconf.as: Fix quoting for autom4te options.
1509 * lib/Autom4te/General.pm (shell_quote): New function, taken
1510 from coreutils, written by Jim Meyering.

1520 test. Test twice, with special characters allowed on w32, and the
1521 rest. Test leading and trailing whitespace, for `open_quote'.
1522 (autotools and whitespace in file names): New, analogous test.

1524 by Russ Allbery and Eric Blake.

1528 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1529 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1530 (update_file, contents): Use it.
1532 * Makefile.am (autom4te-update): Rewrite for git.
1534 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1536 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1538 Fix copyright years.
1539 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1540 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1542 2007-12-04 Eric Blake <ebb9@byu.net>
1544 Manually resync with gnulib, since 'make cvs-update' no longer works.
1545 * build-aux/config.guess: New upstream version.
1546 * build-aux/config.sub: Likewise.
1548 When using older automake, don't downgrade build-aux/texinfo.tex.

1550 * doc/Makefile.am (TEXINFO_TEX): Add.
1552 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1554 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1555 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1556 #undef as this runs afoul of our new way of creating config.h.
1557 Problem reported by Jim Meyering in
1558 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1560 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1562 Fix autom4te for unusual characters in input file names.
1563 * bin/autom4te.in (files_to_options): Quote active characters
1565 * tests/tools.at (autom4te and white space in file names):
1568 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1569 Document that Tru64 awk always splits $0.
1571 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1573 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1574 `#AT_STOP_...' line at the end of each test.
1576 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1578 * lib/autotest/general.m4 (AT_INIT): For awk line number
1579 extraction script, ensure `$at_group' has a defined value
1580 even for the empty set, and properly quote its usage inside
1583 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1585 * doc/autoconf.texi (Shell Functions): New chapter. Document
1586 IRIX sh $0 issue in functions, move content from ...
1587 (Portable Shell): ... here.
1588 (Shell Script Compiler): Note that shell functions are not
1589 totally unportable any more.
1591 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1592 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1594 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1595 extracting the line numbers of the last needed test.
1597 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1599 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1602 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1604 Fix IRIX testsuite debugging failures: $0 in functions.
1605 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1606 Do not use $0 inside a function, as IRIX sh will set that to the
1607 function name rather than the script invocation name.
1609 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1610 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1612 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1613 to extract test scripts.
1614 (AT_INIT): Extract and cache test script line numbers.
1616 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1618 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1619 subsequent fixups; the awk -> here-document conversion trashes
1620 performance too much with AIX sh.
1622 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1624 * tests/local.at: Do not test m4, perl with AT_TESTED.
1626 Diagnose and guard against write errors dealing with config.status.
1627 The general idea is this: all write failures from `configure'
1628 writing `config.status' are indicated by $ac_write_error, which
1629 is only checked at the end. This is safe because config.status
1630 code is not executed before the file is complete. Other write
1631 failures, be they inside config.status, or in sub shell/awk
1632 scripts spawned from configure or config.status, typically need
1633 earlier checking, as their results are used right afterwards.
1634 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1635 before writing config.status, check afterwards.
1636 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1637 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1638 Set `ac_write_error' for write failures to config.status. Barf
1639 upon write failures to temporary files.
1640 Adjust note about closing and reopening the here-document.
1641 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1642 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1643 reopening the here-document.
1644 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1645 Ensure `ac_write_error' does not escape into config.status.
1646 Also, add a couple of code paths not yet exercised in the test
1647 suite: a config file with input from stdin, and a config header
1649 Suggestion for catching write errors by Bruno Haible.
1651 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1653 Avoid error with Tru64 awk and testsuite lines with many words.
1654 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1655 reads the testsuite, set the field separator to an unusual value,
1656 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1657 even splits the input if $i, i>0, was never accessed in the script.
1659 Revert 2007-10-17 change.
1660 * TODO: Multiline args in config files and headers mean something
1661 different and are not fixed, see
1662 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1663 Report by Stepan Kasal.
1665 * doc/autoconf.texi (Generic Programs): Fix typo.
1667 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1669 AC_*_TOOL does not canonicalize the prefix
1670 * doc/autoconf.texi (Generic Programs): Do not say that
1671 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1673 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1675 Diagnose write errors in config.status instantiations.
1676 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1677 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1679 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1680 Extend test to also check for some write error failures, using...
1681 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1682 Report by Bruno Haible.
1685 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1687 (_AT_CHECK): Use less indentation, to save space.
1689 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1691 Add witness macro for @top_build_prefix@ substitution.
1692 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1693 (_AC_OUTPUT_FILE): Mention it here.
1695 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1696 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1698 * lib/autotest/general.m4 (at_func_test): Remove.
1699 (AT_INIT): Pre-extract test groups into separate files.
1700 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1701 Remove at-test-source files together with the $at_group_dir.
1702 * tests/autotest.at (Long test source lines): New test.
1704 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1706 Shell functions and variables may share a namespace.
1707 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1710 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1712 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1715 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1717 * lib/autoconf/status.m4: Fix a couple of comment typos.
1719 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1721 2007-11-13 Jim Meyering <meyering@redhat.com>
1723 Clean up the rule to create "expr".
1724 * tests/Makefile.am (expr): Don't redirect directly to target.
1725 Redirect just once, not for each echo statement.
1726 Use $@, not literal "expr".
1728 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1730 Don't worry about preprocessor when testing long long.
1731 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1732 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1733 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1734 These no longer check for preprocessor flaws.
1735 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1736 Do not check for preprocessor flaws.
1738 2007-11-13 Jim Meyering <meyering@redhat.com>
1740 Adapt dependencies, now that a version change doesn't modify configure.ac
1741 * GNUmakefile: Remove "make clean" kludge.
1742 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1744 Don't redirect directly to target.
1745 Use $@, not literal "version.m4".
1747 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1749 * doc/autoconf.texi (Making testsuite Scripts): Document
1750 ":;{" shorthand as in previous patch.
1752 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1754 * doc/autoconf.texi (Limitations of Builtins): Document problem
1755 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1757 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1758 Use ":;{" shorthand.
1759 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1761 2007-11-12 Jim Meyering <meyering@redhat.com>
1763 Add more non-srcdir build support.
1764 * GNUmakefile (dummy): Split a long line.
1765 Add -v option to autoreconf invocation.
1767 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1768 * GNUmakefile (dummy): Remove INSTALL.
1770 Remove racy commands to build scripts in bin/ and tests/.
1771 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1772 are guaranteed to be built, remove the rules that tried to build
1773 them. Before, with a parallel build, these rules could lead to
1774 two processes writing tests/wrapper.in concurrently.
1776 Build in man/ only *after* building in bin/ and tests/.
1777 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1778 in both bin/ and tests/.
1780 Accommodate non-srcdir build-from-checkout.
1781 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1782 Use git's --git-dir=$srcdir/.git option.
1783 Add quotes, in case tarball_version_file contains shell meta-characters.
1784 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1785 * configure.ac: Pass "." to git-version-gen.
1787 Avoid spurious test failures due to version skew.
1788 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1790 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1792 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1793 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1794 Remove conftest.dSYM directory.
1795 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1796 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1797 Remove `conftest.*' recursively.
1798 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1799 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1801 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1803 Report and analysis by Jeff Squyres and Peter O'Gorman.
1805 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1807 Fix typos in variable names.
1808 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1810 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1812 Document that $((expression)) is not portable.
1813 * doc/autoconf.texi (Shell Substitutions): Here.
1815 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1817 Ignore configure --help* errors due to LINENO-impaired shells.
1818 * tests/torture.at (Configuring subdirectories, Deep Package):
1819 In the --help* tests in read-only trees, make `.' temporarily
1820 writable again for the `stderr' file, and ignore errors due to
1821 the attempt to write configure.lineno.
1822 Report by Patrick Welche.
1824 2007-11-10 Jim Meyering <meyering@redhat.com>
1826 Generate package.m4 in build-dir, not srcdir.
1827 * tests/Makefile.am (package.m4): Adjust target.
1828 Don't redirect directly to $@.
1829 (CLEANFILES): Add package.m4.
1830 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1832 When running $(AUTOTEST), search "." before searching $(srcdir).
1834 Avoid a race condition that would make parallel "distclean" fail.
1835 * tests/Makefile.am (distclean-generic): Replace the default,
1836 automake-provided rule with an identical one, but with an additional
1837 dependency on distclean-local. Simply adding the dependency would
1838 cause automake not to emit the rule at all.
1839 * BUGS: Building with -jN works, now.
1841 Distribute git-version-gen.
1842 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1843 since GNUmakefile is distributed, and requires it for dist* rules.
1845 Remove two more generated files from version control.
1846 * INSTALL: Remove generated file.
1847 * lib/autoscan/autoscan.list: Remove generated file.
1849 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1851 * GNUmakefile (PATH): Remove stray apostrophes; they become
1852 part of PATH, which isn't wanted here.
1854 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1856 New config files output variable `top_build_prefix'.
1857 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1859 * doc/autoconf.texi (Preset Output Variables): Document it.
1861 Report by Bob Friesenhahn.
1863 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1864 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1865 function, to parametrize arithmetic with expr vs. the shell.
1866 Use it where possible.
1867 Suggestion by Benoit Sigoure.
1869 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1871 Adjust the documentation of autotest WRT atlocal.
1872 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1873 when using Automake, to write a rule to produce atlocal, since it's
1874 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1875 distributed, not atconfig.in.
1877 2007-11-04 Eric Blake <ebb9@byu.net>
1879 Update list information.
1880 * README: Mention new autoconf-commit list.
1881 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1883 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1885 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1887 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1889 * build-aux/.gitignore: Ignore mkinstalldirs.
1891 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1893 2007-11-03 Jim Meyering <meyering@redhat.com>
1895 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1896 * build-aux/git-version-gen: This syncs from coreutils.
1898 Adjust the build procedure so "make check" works reliably.
1899 * README-hacking: Include an extra step between "make" and
1900 "make check" to ensure that the latter passes.
1902 Use just-built tools, when possible.
1903 * GNUmakefile (PATH): Set and export here, ...
1904 (dummy): ... rather than here.
1906 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1907 and Andreas Schwab <schwab@suse.de>
1909 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1912 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1914 * configure.ac (AC_PREREQ): Require version 2.60, for
1915 AC_PROG_SED, AC_PROG_GREP.
1917 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1918 and Jim Meyering <meyering@redhat.com>
1919 and Andreas Schwab <schwab@suse.de>
1920 and Eric Blake <ebb9@byu.net>
1922 Document a bug in GNU Bash with compound commands and redirections.
1923 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU

1927 2007-11-03 Eric Blake <ebb9@byu.net>
1929 Support m4 1.4.5 in testsuite.
1930 * tests/torture.at (Define a newline): Exclude line numbers in
1932 Reported by Ralf Wildenhues.
1934 2007-11-03 Jim Meyering <meyering@redhat.com>
1936 Remove automake-provided files from version control.
1937 * build-aux/elisp-comp: Remove file.
1938 * build-aux/install-sh: Remove file.
1939 * build-aux/missing: Remove file.
1940 * build-aux/mdate-sh: Remove file.
1941 * build-aux/.gitignore: New file.
1942 Suggestion from Ralf Wildenhues.
1944 2007-11-03 Eric Blake <ebb9@byu.net>
1946 Adjust version comparison to account for git snapshot numbers.
1947 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1948 component separator.
1949 * doc/autoconf.texi (Number processing Macros)
1950 <m4_version_compare>: Document this change.
1951 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1953 2007-10-30 Bruno Haible <bruno@clisp.org>
1955 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1956 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1957 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1958 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1959 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1960 Suggested by Paul Eggert.
1962 2007-10-28 Jim Meyering <meyering@redhat.com>
1964 * README-hacking: Autoconf, Automake, and Perl are required to build.
1965 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1967 2007-10-28 Jim Meyering <meyering@redhat.com>
1969 README-hacking: Recommend running autoreconf -vi.
1970 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1971 so that we use just-built tools when they're available.
1972 Suggestions from Ralf Wildenhues.
1974 2007-10-28 Jim Meyering <meyering@redhat.com>
1976 Make inter-release --version output more useful.
1978 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1979 which indicates that it is built using the 19th change set
1980 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1981 is a prefix of the commit SHA1.
1982 * build-aux/git-version-gen: New file.
1983 * configure.ac: Run it to set the version.
1984 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1985 * Makefile.am (dist-hook): Arrange so that .version appears only
1986 in distribution tarballs, never in a checked-out repository.
1987 * .gitignore: Add .version here, too. Just in case.
1988 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1989 not configure.ac, now that the version number changes automatically.
1991 Ensure that $(VERSION) is up to date for dist-related targets.
1992 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1993 git-version-gen doesn't match $(VERSION), but only for dist targets.
1995 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1997 Fix `Deep Package' failure with a configure script early in PATH
1998 * tests/torture.at (Deep Package): Add `.' early in PATH.
1999 Report by Jim Meyering.
2001 2007-10-27 Jim Meyering <meyering@redhat.com>
2003 Remove all generated files from version control.
2004 * aclocal.m4: Remove.
2005 * configure: Remove.
2006 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2007 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
2008 * README-hacking: New file: how to build from just-checked-out sources.
2010 2007-10-23 Eric Blake <ebb9@byu.net>
2012 Improve corner case of m4_expand.
2013 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
2015 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
2016 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2019 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
2021 * doc/make-stds.texi: Update from gnulib.

3269 for C++; this drops support for anonymous struct and union types,
3270 which were problematic anyway.

3290 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3291 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3292 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3293 works but the latter doesn't, then it's a valid type.
3294 This lets people use function types and so forth.
3295 For C++ there doesn't seem to be a simple solution, so leave it alone.
3296 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3297 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3298 AC_CHECK_TYPE; that wasn't documented or necessary.

3505 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3507 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3509 * doc/autoconf.texi: Fix some typos.
3511 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3513 Fix some wording problems noted by Paolo Bonzini in:
3514 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3515 * doc/autoconf.texi (Signed Overflow Examples): Give more
3516 discussion about the allow_superuser_privileges example,
3517 and change it a bit to make things clearer.
3518 (Optimization and Wraparound): Clarify whether the compiler
3519 will generate an infinite loop for the example derived from
3520 Autoconf's mktime test.
3521 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3522 Also, clarify unsigned multiplication overflow.
3524 2007-01-04 Eric Blake <ebb9@byu.net>
3526 * bin/Makefile.am (RELEASE_YEAR): New macro.
3527 (edit): Use it to supply correct copyright year to scripts.
3528 * bin/autoconf.as (version): Use it.
3529 * bin/autoheader.in ($version): Likewise.
3530 * bin/autom4te.in ($version): Likewise.
3531 * bin/autoreconf.in ($version): Likewise.
3532 * bin/autoscan.in ($version): Likewise.
3533 * bin/autoupdate.in ($version): Likewise.
3534 * bin/ifnames.in ($version): Likewise.
3536 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3538 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3539 feedback. The most important changes document what happens when
3540 you convert an out-of-range value to a signed integer type, and
3541 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3544 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3545 rewrite, taking notions from the recent discussion on the gcc and
3546 autoconf mailing lists; please see
3547 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3548 and follow the many links.
3549 (Integer Overflow Basics, Signed Overflow Examples):
3550 (Optimization and Wraparound, Signed Overflow Advice):
3551 (Signed Integer Division): New sections.
3553 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3555 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3556 preprocessor macro arguments in traced name.
3557 * doc/autoconf.texi (Defining symbols): Document longstanding
3558 support for AC_DEFINE-ing macros with arguments, and document
3559 behavior when the same variable has multiple AC_DEFINEs.
3560 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3561 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3562 macros directly, giving much shorter and simpler code.
3564 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3566 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3567 space before "$ac_configure_args" to prevent a 'config.status
3568 --recheck' failure if ac_configure_args doesn't contain a leading
3569 space. This works around a problem with the XEmacs configure.ac,
3570 which uses the (undocumented) ac_configure_args variable
3571 inconsistently with Autoconf.
3573 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3575 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3576 Include <limits.h>, and use its INT_MAX to rewrite the
3577 j loop so that it does not overflow 'int'. Problem reported by
3579 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3580 Play it safe by shifting left by 1 rather than multiplying by 2,
3581 as GCC is less likely to optimize this away when the value
3582 is signed (when it assumes overflow leads to undefined behavior).
3583 Also, don't assume time_t uses two's complement.
3585 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3587 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3588 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3589 dumps core on it. Report by Tim Rice.
3591 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3593 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3594 --disable-option-checking to --help output even when
3595 AC_PRESERVE_HELP_ORDER is not used.
3596 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3597 --with argument, rather than argument with [-.] replaced by
3599 * NEWS: Fix typo in previous change; the news was in the
3602 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3604 * NEWS: Warnings are now generated by default for unknown
3605 --enable-* and --with-* options.
3606 * doc/autoconf.texi (Option Checking): Renamed from
3607 (Configure Option Checking). Tighten up the wording a bit.
3608 (External Software, Package Options): Cross-reference to Option
3609 Checking, and use this to shorten our section.
3610 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3611 "$x" to test "x$foo" != x.
3612 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3613 Don't warn if $enable_option_checking is "no".
3614 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3615 ac_unrecognized_opts to the empty string.
3616 Don't echo the unrecognized opts, as this might mishandle
3617 backslashes or leading -.
3618 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3619 usage next to the other --disable-FEATURE options in the
3622 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3624 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3625 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3626 Print warning for unrecognized --with and --enable options
3627 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3628 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3629 Disable option checking when subdirs are configured.
3630 (AC_OUTPUT): If warnings are enabled, print warning about
3631 unrecognized --with and --enable options at the end of
3632 the configure output (as well as at the beginning).
3633 * doc/autoconf.texi (Option Checking): New node.
3634 Document new option warning functionality.
3636 2006-12-16 Eric Blake <ebb9@byu.net>
3638 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3639 * NEWS: Start news for current version.
3641 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3643 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3644 Define HAVE_GETMNTENT to 1, not to the empty string.
3645 Problem originally reported by Jochen Friedrich in
3646 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3648 This change prompted by a problem report by Andrey Simonenko in
3649 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3650 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3651 object-like macros only, in the traditional portable character
3653 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3654 Warn about attempts to define things that are not identifiers.
3655 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3656 awful hack that AC_DEFINEd macro names containing parentheses.
3658 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3660 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3661 too drastic, even if Texinfo in theory requires it for info mode.
3663 (config.status Invocation): Renamed back from Recreating a
3665 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3666 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3668 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3670 * NEWS: Version 2.61a.
3672 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3673 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3675 * NEWS: Document changes with echo and printf, and the lack
3676 of limits on the total size of multi-line values of substituted
3677 variables, and the AC_FUNC_FSEEKO fix.
3679 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3681 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3682 Writing configure.ac.
3683 (Autoconf Input Layout): Renamed from configure.ac Layout.
3684 (Recreating a Configuration): Renamed from config.status Invocation.
3685 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3686 (acconfig Header): Renamed from acconfig.h.
3687 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3688 (Writing Testsuites): Renamed from Writing testsuite.at.
3689 (Autom4te Cache): Renamed from autom4te.cache.
3691 * BUGS: Remove mention of VPATH problem, since it's now documented
3692 not to be a bug in the Autoconf build procedure itself, but rather
3693 a problem with the proprietary `make' programs.
3695 * doc/autoconf.texi (Build Directories): Add a cross reference
3698 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3699 * doc/standards.texi: Sync from gnulib.
3701 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3702 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3703 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3704 generated automatically.
3706 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3708 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3709 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3710 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3712 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3714 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3715 `CEOF$ac_eof' special marker, the awk script cannot contain a
3716 line matching `^CEOF', so this is not needed any more.
3717 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3718 special marker in the test.
3720 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3722 * tests/tools.at (autom4te preselections): Use `find -newer';
3723 remove one of the sleeps.
3725 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3726 more readable, using ...
3727 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3729 * doc/autoconf.texi (autoheader Invocation): Do not double-
3730 quote the parameter of `AH_BOTTOM' in the example.
3732 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3734 * doc/autoconf.texi (Configuration Headers): Remove the
3735 example with multiple input files.
3736 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3737 multiple input files.
3739 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3741 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3742 creating the awk substitution script, handle one input line at a
3743 time, so that the maximum length of a substituted (multi-line)
3744 value is not limited by the size of the sed pattern space.
3745 The trade-off is a slightly repetitive sed script.
3746 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3747 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3748 * tests/torture.at (Substitute a 2000-byte string): Increase the
3749 test with several long lines, they should not be caught by sed
3752 * tests/tools.at (autom4te preselections): New test, to flag
3753 entries missing from autom4te.cfg.
3754 Report by David Byron <dbyron@hheld.com>.
3756 * tests/torture.at (Substitute a 2000-byte string): Actually use
3757 AC_PROG_AWK, so the last change works as intended.
3758 (Substitute and define special characters): Likewise.
3759 (Substitute a newline): Likewise.
3761 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3762 instead of `awk' consistently.
3763 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3764 * tests/torture.at (Torturing config.status): Test both the
3765 result of AC_PROG_AWK and plain awk.
3766 (Substitute a 2000-byte string): Likewise.
3767 (Substitute and define special characters): Likewise.
3768 (Substitute a newline): Likewise.
3770 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3772 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3773 can be assigned to a function pointer. Problem reported by
3774 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3775 part of a patch by Ralf Wildenhues in that same bug report.
3777 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3779 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3780 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3782 2006-12-01 Eric Blake <ebb9@byu.net>
3784 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3785 cross-compiling from cygwin to mingw.
3786 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3787 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3788 to lib/autoconf/c.m4.
3790 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3792 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3793 string for more reliable failure. Wrap the entire test that
3794 causes the broken Solaris printf to dump core, in a subshell,
3795 so the segmentation fault message is reliably suppressed.
3796 Fix shell expansion errors by using /usr/ucb/echo always;
3797 avoid an error on systems without it by another subshell.
3798 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3799 subshell-$as_echo to `as_echo', for better error message.
3801 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3803 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3804 `BASH_SOURCE' contain a newline, set them to empty, as they may
3807 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3809 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3810 years and is too hard to maintain now. The last straw was
3811 reported by Jerker Baeck in
3812 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3813 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3814 * doc/autoconf.texi (Particular Functions): Move
3815 AC_FUNC_SETVBUF_REVERSED from here...
3816 (Obsolete Macros): ... to here. Say that it does nothing now.
3817 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3818 Turn into (almost) a no-op.
3820 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3822 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3823 These macros are obsolescent and new applications shouldn't need them.
3824 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3825 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3826 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3827 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3828 (AC_FUNC_VPRINTF): Likewise.
3829 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3830 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3831 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3833 * doc/autoconf.texi (Setting Output Variables): Mention that
3834 @VAR1@VAR2 has unspecified behavior. Problem reported by
3836 * NEWS: Mention this.
3838 * Makefile.am: Put only a single '#' into the copyright notice,
3839 so that it's also present in the output file. Standardize wording
3840 in makefile copyright notices to match GNU coding standards.
3841 * bin/Makefile.am: Likewise.

3854 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3856 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3857 in the sed script that mangles the awk script: delete up to the
3858 first exclamation mark only.
3859 * tests/torture.at (Substitute and define special characters):
3862 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3864 Rewrite config files generation: avoid quadratic growth in
3865 the number of substituted variables by using awk instead of sed
3866 for the bulk of the substitutions.
3867 * NEWS: Mention this.
3868 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3869 forbidden in the output (and thus input) file.
3870 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3871 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3872 generate just one large awk script for substitutions,
3873 eliminating much of the earlier complexity, while adding some
3874 new complexity. Only expand the substitution templates at
3875 configure time, for smaller configure script size. If
3876 _AC_SUBST_FILES are used, test 'awk' for working getline support
3877 at config.status time. If absent, interpolate through the
3878 shell. The awk script was written with much help
3879 from Paolo Bonzini and Paul Eggert.
3880 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3881 (_AC_SED_FRAG_NUM): Likewise.
3882 (_AC_SUBST_CMDS): Renamed from...
3883 (_AC_SED_CMDS): ...this.
3884 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3885 * tests/torture.at (Substitute a 2000-byte string): Also
3886 substitute a line with 1000 words, and a variable with several
3888 (Substitute and define special characters): Test awk special
3889 characters, and put substitution input strings `@foo@' in the
3890 output, to test that no recursion happens; test several other
3891 combinations from Paolo Bonzini.
3893 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3895 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3896 that replaced echo with AS_ECHO where this wasn't necessary.
3897 Problem reportd by Ralf Wildenhues.
3898 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3899 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3900 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3902 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3904 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3906 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3908 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3909 that traditional Awk lacks 3-arg "split". It has it.
3910 Mention that FS must be a single character, and a few other
3911 99-byte limits of traditional Awk.
3912 Mention that if (i in a) doesn't work with traditional Awk.
3914 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3916 * tests/autotest.at (BSx641-newline in command):
3917 (BS-BS-newline in command, BSx640-newline in command):
3918 (Newline-CODE-BS-newline in command):
3919 (Single-quote-BS-newline in command):
3920 (Single-quote-newline-BS-newline in command):
3921 Use printf '%s\n' instead of echo, for portability to hosts
3922 where echo interprets backslashes. This will break on hosts
3923 that lack printf, but for now let's assume all such hosts
3924 are dead (if not, we should get reports of test failures).
3926 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3928 'echo' has some portability problems, when given a first argument
3929 with a leading '-', or when given any argument containing '\'.
3930 Avoid using 'echo' in these cases.
3931 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3934 * lib/autotest/general.m4 (AT_INIT): Likewise.
3935 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3936 argument might be unportable.

3950 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
3951 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):

3954 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3955 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3956 * bin/autoconf.as: Redo verbose flag implementation, as the old
3957 scheme wouldn't work with AS_ECHO.
3958 * lib/autotest/general.m4 (AT_INIT): Likewise.
3959 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3960 Don't use ECHO_T, since ECHO_N is now reliable.
3961 * lib/autotest/general.m4 (AT_INIT): Likewise.
3962 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3963 rather than using a here-document to put the script into a file.

3967 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3968 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3969 bug, but we might as well stop using ECHO_N and ECHO_C internally.

3972 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

3974 operand, as AS_ECHO requires. Avoid double file name expansion.
3975 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3976 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3977 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3978 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

3980 Double-quote strings that would otherwise contain M4 comments.
3981 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3983 * configure.ac (AC_INIT): Bump to 2.61a.
3986 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3990 * configure.ac (AC_INIT): Bump to 2.61.
3993 * tests/autotest.at (Macro with backslash in a test title):
3994 Comment out for now, as this tests neither fails nor passes
3995 reliably. Problem reported by Ralf Wildenhues.
3997 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3999 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

4074 benefit of platforms like Solaris+GCC where it is common to have a
4075 non-working g++ installation.
4077 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4078 and Joel E. Denny <jdenny@ces.clemson.edu>
4079 and Paul Eggert <eggert@cs.ucla.edu>
4081 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4082 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4085 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4087 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4088 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4089 Imported from a similar patch to gnulib by Bruno Haible.
4091 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4093 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4110 and Stepan Kasal <kasal@ucw.cz>
4112 Handle special characters in test case titles correctly.
4113 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4115 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4116 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4117 argument. Extend to check titles printed by ./micro-suite and

4120 Single-quote in a test title,
4121 Double-quote in a test title): Don't expect failure anymore.
4122 (Backslash in a test title): Put a non-whitespace character after the
4123 backslash so that Bourne shells might actually see it as an escape
4125 (Brackets in a test title,
4126 Pound in a test title,
4127 Comma in a test title,
4128 Quoted Macro in a test title,
4129 Macro in a test title,

4131 (Macro with backquote in a test title,
4132 Macro with double-quote in a test title,
4133 Macro with backslash in a test title): New tests expected to fail.
4134 * tests/torture.at (#define header templates): M4-quote this title in
4135 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4136 The visible effect was a stray [] in the testsuite output.
4138 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4140 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4141 `trap ... 0' inside a function, for AIX sh.
4143 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4145 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4146 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4147 5363) simply issues a warning when dividing by zero at compile
4148 time. Problem reported by Elias Pipping.
4150 2006-10-26 Eric Blake <ebb9@byu.net>
4153 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4154 show effect on macros that expand with commas.
4155 Reported by Joel E. Denny.

4177 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
4179 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4181 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4182 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4183 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4184 reported by Nelson H. F. Beebe for Coreutils 6.4.
4186 * tests/tools.at (autoconf --trace: user macros): Remove test
4187 for tracing multiline macros, since m4 1.4.7a uses a different
4188 way to number lines. Problem reported by Ralf Wildenhues.
4190 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4192 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4193 /dev/null since the heuristics for interactive behaviour was

4197 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4199 * bin/autoconf.as: Fix the verbose message at the end.

4214 * NEWS: Remove AC_CACHE_CHECK_INT.
4215 * doc/autoconf.texi (Caching Results): Likewise.
4216 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4217 AC_CACHE_CHECK_INT, since it's no longer public.
4218 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4219 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4221 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4247 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4249 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4250 looking for special shell characters.
4251 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4252 macro defined by AS_VAR_PUSHDEF before passing it as a

4264 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4266 (Imported from Automake.)
4267 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4268 which incorrectly sets the mode of an existing destination
4269 directory. In some cases the unpatched install-sh could do the
4270 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4271 system. We hope this is rare in practice, but it's clearly worth
4272 fixing. Problem reported by Alex Unleashed in
4273 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4274 Also, don't bother to check for -m bugs unless we're using -m;
4275 suggested by Stepan Kasal.
4277 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4279 Import this change from Automake:
4281 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4282 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4283 is enabled by default with gnu and gnits strictness.
4284 Report from Bruno Haible.
4286 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4287 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4288 gnu and gnits modes.
4290 Import this change from Config:
4292 2006-09-20 Ben Elliston <bje@gnu.org>

4295 Import this change from Gnulib:
4297 2006-09-16 Karl Berry <karl@gnu.org>
4298 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4299 to avoid sectioning errors.
4301 Import these changes from Texinfo:
4303 2006-10-04 Karl Berry <karl@gnu.org>
4304 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4305 (\quoteexpand): rename to \rquoteexpand.
4306 (\codequoteleft): new def, to look for @set codequotebacktick.
4307 (\lquoteexpand, \quoteexpand): new defs.
4308 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4309 (\code): must use new \...Char values, since now ` is active.
4311 2006-08-26 Karl Berry <karl@gnu.org>
4312 * build-aux/texinfo.tex (\textdegree): New command.
4314 2006-08-12 Karl Berry <karl@gnu.org>
4315 * build-aux/texinfo.tex (error \box0): smaller font.

4319 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4321 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4323 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4324 added to the template can get mangled.
4326 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4328 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4329 include the default headers, and redefine obstack_chunk_alloc
4330 and obstack_chunk_free. Fixes false failure with glibc.
4332 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4334 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4335 for backward compatibility with Libtool 1.5.22. Problem reported
4338 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4340 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4342 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4344 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4346 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4347 the NonStop platform.
4348 * doc/autoconf.texi (Posix Variants): Likewise.
4349 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4351 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4352 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4353 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4354 Use a better substitute, by inspecting the output of "ls"
4355 rather than just using ":".
4356 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4357 rather than AS_EXECUTABLE_P, since we needn't worry about
4358 non-regular files here.
4360 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4361 due to configuration hassles with this. See Tonya Underwood's report
4362 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4363 * doc/autoconf.texi (Special Shell Variables): Likewise.
4365 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4366 Stepan Kasal <kasal@ucw.cz>
4368 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4369 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4371 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4373 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4374 initialization which is not inherited through the environment
4375 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4376 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4378 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4380 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4381 problems with mkdir -p -m.
4383 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4385 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4386 comment about ac_cpp_err; it was incorrect, and anyway
4387 ac_cpp_err is being removed below.
4388 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4389 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4390 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4392 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4393 with werror_flag and conftest.err and so forth. This is more
4394 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4395 and anyway the user shouldn't normally want to see this gorp logged.
4396 Problem reported by Ralf Wildenhues.
4397 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4398 empty, not 'no', since the rest of the code uses 'test -z'.
4400 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4402 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4403 Use a single call to AC_DO_TOKENS rather than multiple, for
4405 (_AC_LINK_IFELSE): Test that resulting file is executable.
4406 Problem reported by mwoehlke in
4407 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4409 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4410 than creating a file to use with test -x; this is much faster.
4412 2006-10-02 Bruno Haible <bruno@clisp.org>
4414 * lib/autom4te.in (Automake-preselections): Add
4415 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4417 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4419 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

4873 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4874 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4876 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4878 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4879 after -R regardless of host. Patrick Welche reports that this
4880 fixes things on NetBSD 3.99.
4882 * NEWS: Recommend M4 1.4.5.
4884 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
4885 * tests/tools.at (autom4te cache): Update wording of diagnostic
4888 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4890 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4891 under AC_C_VOLATILE.
4892 (Volatile Objects): Be a little less skeptical about what
4893 "volatile" means. Derived from thoughts by Ben Pfaff in
4894 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4896 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4898 * doc/autoconf.texi: Fix some typos.
4900 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4902 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4903 more globally, since the 2006-06-30 patch didn't suffice. Problem
4904 reported by Keith Marshall. Also, don't bother with builddir2,
4905 since it shouldn't be needed any more.
4907 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4909 * doc/autoconf.texi (Generic compiler characteristics):
4910 Document AC_COMPUTE_INT. Fix wrong statements on Default
4911 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
4913 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
4914 (_AC_COMPUTE_INT): Add obsoletion warnings.
4915 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
4918 * NEWS: Document change.
4920 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
4922 * doc/autoconf.texi (Volatile Objects): New section.
4924 * NEWS: Document previous change.
4926 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4928 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4929 Require that long long int be at least 64 bits wide. C99 requires
4930 this and enough programs depend on it so we should check for it.
4931 Bruno Haible reports in
4932 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4933 that long long int is 32 bits wide with some nonstandard compilers.
4934 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4936 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4938 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4939 to a nonexistent file, so that we don't have to worry about
4940 a local site configuration that doesn't use /usr/local.
4941 Problem reported by Keith Marshall in
4942 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4944 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4946 * doc/autoconf.texi: Be more consistent about using @acronym with
4947 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4948 quite right (it talked about "OSF/Tru64", even though the
4949 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4950 and it even mentioned "OSF 4"!) and at this point there's little
4951 reason to talk about OSF any more, since it died in 1994.
4952 (Specific Compiler Characteristics): Simplify example of
4953 negative-size array.
4954 (File Descriptors): Reorder to make the text flow better.
4955 Remove joke about "appreciate the various levels"; I didn't get it.
4956 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4957 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4958 (File Descriptors, Limitations of Usual Tools):
4959 Tone down the advice against renaming or removing open files.
4960 (Limitations of Usual Tools): Add a new section, on 'rm'.
4962 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4964 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4965 -lXt in LIBS, idea from Karsten Hopp; this was due since
4968 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4969 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4970 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4971 (which belong to Xt, not X itself). See Debian bug 327655.
4973 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4975 * configure.ac (AC_INIT): Bump to 2.60a.
4978 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4982 * configure.ac, NEWS: Update.
4984 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4986 * config/texinfo.tex: Sync from upstream.
4988 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4989 quadrigraph correctly in traces.
4991 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4994 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4995 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4997 * doc/autoconf.texi (Changed Directory Variables): New node,
4998 to document the whole `datarootdir' business a bit better.
5000 * tests/torture.at (datarootdir workaround): Extend test.
5001 Prompted by report by Alexandre Julliard.
5003 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5005 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5006 when using default mode of IBM C 6 for AIX. Problem and two-line
5007 fix reported by Larry Jones.
5009 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5011 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5012 about literal '${datarootdir}' if a definition is found in the
5015 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5017 * NEWS: Use "M4" rather than "m4" when appropriate.
5018 Problem reported by Eric Blake.
5019 * doc/autoconf.texi: Likewise.
5020 Use @acronym around BSD, GCC, and GNU when appropriate.
5021 (Why GNU M4): Renamed from "Why GNU m4".
5022 (Redefined M4 Macros): Mention that Posix
5023 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5024 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5027 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5029 * bin/autom4te.in (handle_output): Do not forbid the empty
5031 * tests/tools.at (autoconf: the empty token): New test.
5033 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5035 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5036 calls, so that we do not care whether they are LIFO or FIFO;
5037 in the m4_wrap, do not check which diversion is the topmost
5038 one, just check that the stack is balanced at the end.
5039 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5040 base diversion forever--pop the previous diversion before
5041 opening the new one; consequently, remove the m4_wrap call.
5042 * lib/autotest/general.m4 (AT_INIT): Likewise.
5043 * tests/m4sugar.at: Do not use
5044 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5046 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5047 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5049 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5050 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5051 Rework example of m4wrap token-pasting trouble so that it doesn't
5052 care whether it's LIFO or FIFO.
5053 Fix some "contrary to"s that are awkward in English.
5055 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5057 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5058 to `yes' instead of `int$1_t' if the type is found, for more
5059 consistent configure output (where $1 is the number of bits).
5060 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5061 Suggested by Bruno Haible.
5063 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5064 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5065 with system headers. Report by Bruno Haible.
5067 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5069 * config/config.guess, config/config.sub: Sync from upstream.
5071 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5072 in order to avoid picking up an older installed frozen m4sh.m4f.
5073 Besides an outdated shell startup, this could have been created
5074 by an earlier M4 version with incompatible frozen file format.
5076 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5078 * README: Recommend m4 1.4.4 instead of 1.4.3..
5079 * doc/autoconf.texi: Likewise.
5080 (Special Chars in Names): Say that $(.FOO) is portable, as
5081 suggested by Stepan Kasal.
5082 (Installation Directory Variables, Build Directories):
5083 (Automatic Remaking, Subdirectories, Fortran Compiler):
5084 (Making testsuite Scripts, Defining Directories):
5085 Quote variable usages better.
5086 (Making testsuite Scripts): Add clean-local rule to makefile
5087 snippet, by Eric Blake.
5088 (Installation Directory Variables): Fix table item font.
5089 Reword slightly to clarify. Generalize advice about
5090 not using special characters to include all file-related
5091 vars, not just VPATH.
5092 (Special Chars in Variables): Warn about special characters in
5094 (Assignments): Clarify default-value example as suggested by
5096 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5097 (Special Shell Variables): Note leading ./ or ../, as suggested
5099 (Limitations of Builtins): Under cd, warn about CDPATH.
5100 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5103 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5105 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5106 `@var', for texi2html.
5107 (Systemology): Some more word wrapping, for DVI output.
5108 (autom4te Invocation): The short option for `--melt' is `-M',
5111 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5113 * doc/autoconf.texi: More formatting and English tweaks,
5114 many suggested by Ralf Wildenhues.
5115 Reword to avoid "@code{...}'s" and the like, since it's ugly
5116 with Emacs info mode. discontents -> woes.
5117 Put a few "will"s back. time stamp -> timestamp.
5118 side-effect -> side effect.
5120 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5122 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5123 Warn about $@ not persisting. Problem reported by Julien Danjou in
5124 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5125 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5126 Mention other special chars, too.
5128 2006-06-14 Eric Blake <ebb9@byu.net>
5130 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5132 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5134 * doc/autoconf.texi: Some systematic minor improvements, as
5135 follows. Use "makefile" when talking about makefiles
5136 generally (which might be named "makefile" or "Makefile" or even
5137 "foo.mk"), "Makefile" when talking about a specific makefile
5138 called "Makefile". This unclutters the text from weird quotes
5139 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5140 values" rather than "@var{foo}s" and similar constructs containing
5141 "}s". Use "Make rules" rather than "Makefile rules". Minor
5142 English-language improvements. Change the prefix "sub-" to "sub"
5144 Put blank lines around examples more consistently.
5145 Avoid "rather" and "very" as intensifiers.
5146 Avoid "will" as an auxiliary.
5147 (Limitations of Make): Split this node into....
5148 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5149 (Leading _ in Macro Names, Backslash-Newline-Newline):
5150 (Backslash-Newline Comments, Long Lines in Makefiles):
5151 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5152 (obj/ and Make, make -k Status, VPATH and Make):
5153 (VPATH and Double-colon, $< in Explicit Rules):
5154 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5155 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5156 New nodes, resulting from splitup of Limitations of Make.
5157 All cross-references changed. Raise the top node from
5158 a section to a chapter, and all subnodes accordingly.
5159 Redo the introductory wording to match the new organization.
5160 (Installation Directory Variables): Use an example that is
5161 closer to what Autoconf actually does. Mention that VPATH's
5162 value should not contain metacharacters or white space.
5163 (Fortran Compiler): Fix a VPATH bug in an example.
5164 (Leading _ in Macro Names): Mention that this problem is no longer
5165 of practical concern.
5166 (VPATH and Make): Reword the advice to make it clearer
5167 that Autoconf and Automake support VPATH in non-GNU make, but
5168 many packages have bugs in this area.
5169 ($< in Explicit Rules): Refer to Build Directories rather
5170 than using a (non-VPATH-safe) example.
5171 (Automatic Rule Rewriting): Mention the sort of disaster that
5172 can ensue with Solaris-style rule rewriting with VPATH.
5174 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5176 * doc/install.texi (Compilers and Options): Weaken the
5177 suggestion to use GNU make for VPATH builds.
5179 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5180 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5182 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5183 in regular expression.
5185 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5187 * doc/autoconf.texi (Installation Directory Variables):
5188 Drop extra @samp from `@table @samp' item.
5189 (Limitations of Usual Tools): Comment fix.
5190 Do not nest @samp just to point to other table items.
5191 (Writing testsuite.at) <AT_CHECK>: The second argument to
5192 `@dvar' is already @samp'ed.
5193 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5194 do not use @var in the second argument.
5196 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5198 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5199 $as_shell.exe too. Problem reported by Andreas Buening in
5200 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5202 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5204 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5205 `unused variable' compiler warning, for `-Wall -Werror'.
5206 Reported by Jaap Haitsma in
5207 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5209 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5211 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5212 case the compiler dumps core. Problem reported for
5213 OpenServer 5.0.7 by Tim Rice in
5214 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5215 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5218 2006-06-06 Tim Rice <tim@multitalents.net>.
5220 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5221 "ERROR" only shows up in "make check" output if there is an
5224 2006-06-06 Eric Blake <ebb9@byu.net>
5226 * tests/tools.at (automatically allowed tokens): Fix typo.
5228 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5230 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5232 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5233 typically overflows on x86 CPUs, even though the C standard
5236 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5238 * configure.ac (AC_INIT): Bump to 2.59e.
5241 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5245 * config/texinfo.tex: Sync from upstream.
5247 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5248 seen, invoke libtoolize with `--ltdl' argument.
5249 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5251 Suggested by Eric Blake.
5253 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5255 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5256 reported by Ralf Wildenhues.

5270 message issued by AC_REQUIRE.
5271 * tests/m4sugar.at: Check m4_require's error message.
5272 * tests/base.at: Check AC_REQUIRE's error message.
5273 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5275 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5277 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5278 `expout' as the last parameter.
5279 * tests/tools.at: Adapt to the above change.
5281 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5283 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5284 information about race-free implementations of mkdir.

5293 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5295 * NEWS: GNU make now recommended for VPATH builds.
5296 Mention that some macros are now documented to be obsolescent.
5297 * doc/autoconf.texi:
5298 Prefer "current" to "modern" to describe
5299 currently-used (albeit perhaps old-fashioned) hosts.
5300 Mention which ancient features no longer need to be worried about.
5301 setgid -> set-group-ID
5302 setuid -> set-user-ID (these are the Posix terms)
5303 Fix some misuses of "only".
5304 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5305 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5306 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

5315 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5316 Mention that it's now safe to use 3 and 4.
5317 (Limitations of Usual Tools): cp -r is now specified by Posix.
5318 Omit longwinded and obsolescent discussion of cp -f.
5319 Modernize discussion of expr, ls.
5320 (Limitations of Make): Modernize discussion of VPATH builds.
5321 Mention $? as a workaround in some cases.
5322 * doc/install.texi (Basic Installation):
5323 Mention "./configure; make; make install" first. Be more
5324 specific about why this file is generic. Remove unnecessary
5325 parens. Remove misleading "only". Remove obsolete advice
5326 about csh. Don't say "configure" takes awhile; say it
5327 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5328 and CC=c99 rather than CC=c89, as these are blessed by current
5329 Posix. Recommend GNU make if doing a VPATH build.
5331 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5333 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5334 examples involving shell prompts.

5354 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5355 about quoting the case statement, just in case.
5356 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5357 was fixed in ksh93g; reported by Ralf Wildenhues.
5359 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5361 * doc/autoconf.texi (System Services): Do not document
5362 overriding EXEEXT via ac_cv_exeext=ext.
5363 (Particular Programs) <AC_PROG_MKDIR_P>:
5364 Document that ${MKDIR_P} understands --.
5365 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5368 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5370 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5371 argument with leading hyphen. Problem reported by Paul Eggert.
5373 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5375 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5376 about quoting ac_try: quote all of it, if any of it seems suspicious.
5377 This means we don't have to worry about ${ or sed any more.
5378 Also, double-quote the case statement, to work around misuses via
5379 underquoting as reported by Ralf Wildenhues in
5380 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5381 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5382 undocumented and dangerous macro.
5383 Problem reported by Ralf Wildenhues in
5384 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5386 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5388 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5389 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5390 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5392 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5394 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5395 since evidently some packages rely on the old, broken behavior.
5396 Problem reported by Ralf Wildenhues in
5397 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5398 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5399 pre-2006-05-26 definitions, but leave in the comments that
5400 these macros are dangerous and should not be used.
5401 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5402 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5403 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5404 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5405 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5407 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5409 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5410 the use of 'tr', since this is our only use of 'tr'.
5412 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5413 and Paul Eggert <eggert@cs.ucla.edu>
5415 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5416 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5418 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5420 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5421 the output file in the `${datarootdir}' test.
5423 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5424 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5426 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5427 mention of `datarootdir' in the input file(s), but literal
5428 `${datarootdir}' in the output file, and we haven't warned yet,
5429 then warn as well: the user may have (erroneously) used
5430 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5431 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5432 * tests/torture.at (datarootdir workaround): Extend this test.
5435 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5436 and Paul Eggert <eggert@cs.ucla.edu>
5438 * doc/autoconf.texi (autoheader Invocation): The first argument to
5439 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5440 alternatives and clear up the language a bit.
5442 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5444 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5445 ac_config_guess, ac_config_sub, ac_configure.
5446 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5447 Fix typo that prevented an unnecessary space from being removed.
5448 Problems reported by Ralf Wildenhues in:
5449 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5451 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5453 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5454 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5455 Don't use the term "thread-safe" to talk about mkdir race
5456 conditions, since the problem is more a process than a thread
5457 issue. Problem reported by Stepan Kasal in:
5458 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5459 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5460 the test for 'install' more closely. Look at MKDIR_P first.
5461 Look in the PATH, and at /opt/sfw/bin.
5462 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5463 Don't bother to try mkdir -p, since we already check mkdir --version;
5464 just look at the version number. (There's no easy way to check
5465 for race-free implementations.)
5466 * tests/tools.at (autoconf: subdirectories): Adjust to above
5467 changes, since MKDIR_P now might end in "/mkdir -p".
5469 * doc/autoconf.texi (autoheader Invocation): Mention that the
5470 first arg of AC_DEFINE_UNQUOTED must be a literal.
5471 Problem reported by Ben Pfaff in
5472 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5474 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5475 * doc/autoconf.texi (Special Chars in Variables): New section.
5476 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5477 (Installation Directory Variables): Quote $(datadir) better.
5478 (Limitations of Builtins): Describe some of eval's trickiness.
5480 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5481 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5482 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5483 in front of every arg, not just trailing args. Quote apostrophes.
5484 (_AC_EVAL_ECHO): New macro.
5485 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5486 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5488 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5489 exposed by quoting of eval argument. Put the command on line line
5491 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5492 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5493 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5494 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5495 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5496 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5497 Use eval more safely.
5498 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5499 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5501 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5502 lines, exposed by quoting of eval argument.
5504 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5505 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5507 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5508 initialization of `ac_cv_exeext', do not override it if it was
5509 already set, unless it was set to `no', for compatibility with
5510 Autoconf-2.13, and comment this.
5511 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5512 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5513 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5514 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5515 Document that this test may be overridden by setting
5518 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5520 Revert these two patches:
5522 2006-04-06 Eric Blake <ebb9@byu.net>
5523 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5524 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5527 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5528 Clean up _AC_COMPILER_EXEEXT* macros.
5529 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5530 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5531 ac_file to the name of the default output file and call
5532 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5533 initial `rm' of the candidate files...
5534 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5535 the same list in subsequent `rm' calls, and for the temporary
5536 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5537 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5538 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5539 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5540 no longer needed) by libtool. Make it a cache check.
5541 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5542 copied here by mistake.
5543 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5544 _AC_COMPILER_EXEEXT.
5545 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5546 _AC_COMPILER_OBJEXT directly.
5547 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5549 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5551 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5552 Fix description of how the buggy `sed' works.
5554 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5558 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5559 ENOLCK. Only mention `make -j' when applicable. Only raise
5560 fatal errors when `make -j' is involved. Improve error message.
5562 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5564 * doc/autoconf.texi (Here-Documents): We now know more about
5565 the variable expansion in here documents bug.
5566 Thanks to Tim Rice and Stepan Kasal.
5568 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5569 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5571 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5573 * tests/autotest.at (Multiline command from M4 expansion):
5574 No failure to be expected if the shell quotes newlines in
5575 commands in the `set -x' output. Report by Tim Rice.
5578 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5580 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5581 expansion in the here-documents used by config.status, as that
5582 runs afoul of the Korn shell version M-12/28/93d bug described in
5583 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5584 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5585 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5587 2006-05-23 Jim Meyering <jim@meyering.net>
5589 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5590 Fix typo introduced with 2006-04-02 change. It reversed the sense
5593 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5595 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5596 ac_dB slightly, to save bytes in the script.
5597 Max out at 50 lines, rather than 96; this is more likely
5598 (though not guaranteed) to avoid obscure 'sed' failures.
5600 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5602 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5603 `tr -d -' as bad option argument. Work around this by deleting
5604 an unrelated character.
5605 Report by Tim Rice <tim@multitalents.net>.
5607 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5608 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5609 Stepan Kasal <kasal@ucw.cz>
5611 * doc/autoconf.texi (Particular Programs): Do not promise that
5612 we always prefer the GNU version of the program, and that we
5613 search according to PATH; both rules can have exceptions.
5614 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5615 AC_PROG_SED. Move descriptions of limitations
5616 to the Limitations of Usual Tools section.
5617 (Limitations of Usual Tools) <sed>: Mention script length
5618 limitations with Solaris /usr/ucb/sed.
5619 <grep>: Fix wording for empty alternative. Mention that -c and
5620 -l should not be combined, and that -E and -F should not be
5623 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5624 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5626 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5627 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5629 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5631 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5632 AC_DEFINE is now passed to m4_pattern_allow.
5633 * NEWS: Mention that; likewise for AC_SUBST.
5634 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5635 the parameter to m4_pattern_allow.
5636 * tests/tools.at: Add a check for that.
5638 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5640 * lib/autoconf/status.m4: Fix typos.
5642 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5644 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5645 only the files that this macro generates.
5647 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5649 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5650 the HP-UX sed limitation of 99 commands, labels do not count.
5651 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5653 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5655 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5657 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5658 Import the following fix from coreutils:
5660 2006-01-13 Jim Meyering <jim@meyering.net>
5662 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5663 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5664 not double-quote uses of that variable, to accommodate the rare
5665 case in which getmntent is available in none of the libraries
5666 checked. This happens at least on FreeBSD 5.0.
5668 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5670 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5671 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5672 some other programs unwisely rely on these undocumented vars.
5673 But put in warning comments about them.
5674 Problem reported by Ralf Wildenhues in
5675 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5676 * NEWS: Document that these variables are intended to go away.
5678 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5680 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5681 and set the language to C++ (analogous to the equivalent Fortran
5684 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5685 * doc/autoconf.texi (C++ Compiler): Document it.
5686 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5689 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5691 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5692 that caused config.status to generate 100-command sed scripts; the
5693 portable limit is 99.
5695 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5697 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5698 variable `ac_d' instead of `d' to avoid infringing namespace.
5699 Report by Ralf Menzel.
5701 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5703 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5704 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5705 * tests/tools.at (autoconf: subdirectories): New test, taken from
5706 the corresponding problem report by Ralf Wildenhues in:
5707 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5709 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5710 Quote some uses of shell variables if they might suffer unexpected
5711 globbing. This doesn't fix all instances of quoting problems that
5712 I found, just the easy ones that look safe.
5713 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5714 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5715 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5716 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5717 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5718 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5719 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5721 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5722 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5724 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5726 * bin/autoreconf.in ($help): Reword according to the manual.
5727 Suggested by Olly Betts.
5729 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5730 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5732 * bin/autoreconf.in: Pass the directory argument to
5733 `require_configure_ac'. Fix comment.
5734 * tests/torture.at (Configuring subdirectories): Expose this.
5735 Reported by Olly Betts.
5737 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5739 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5740 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5741 Automake as follows:
5743 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5744 `$configure_in' instead of `configure.in', to preserve
5745 directory component.
5747 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5749 * config/config.guess, config/config.sub, config/texinfo.tex,
5750 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5752 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5754 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5755 test for C99 conformance; (bool) 0.5 is an integer constant
5756 expression, but (bool) -0.5 is not. Problem reported by Fedor
5757 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5759 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5761 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5762 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5763 Warn about obsolete install-sh files. Remove stray sentence
5764 fragment and fix cross reference.
5765 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5766 install -d; this undoes the 2006-05-10 change.
5767 (MKDIR_P): Mark with AN_MAKEVAR.
5768 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5769 that we don't require $INSTALL to be thread-safe. Move comments
5770 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5771 of AC_PROG_INSTALL. Output a message saying that we're checking
5772 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5773 MKDIR_P instead of AC_SUBST.
5774 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5775 Special magic for MKDIR_P, too.
5776 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5778 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5780 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5782 Sync from Automake, as follows:
5784 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5785 * config/install-sh: Initialize IFS, so field splitting isn't
5787 * config/mkinstalldirs: Likewise.
5788 * config/missing: Remove superfluous quotes. Replace all uses of
5789 `[' by `test', for consistency, and for..
5790 * config/missing (sed_minuso, sed_output): New variables.
5791 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5792 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5793 Fixes `missing' to detect `--output' for help2man. Fixes
5794 PR automake/483. Report by Dennis J. Linse.
5795 (autom4te): Document in `missing --help'.
5797 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5799 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5800 * config/install-sh: Don't use 'path' to talk about file names,
5801 as per GNU coding standards. Close a race condition reported by Ralf
5802 Wildenhues and Stepan Kasal. There is still a race condition
5803 on hosts that predate Posix 1003.1-1992, but we can't help this.
5804 Don't mishandle weird characters like space on pre-Posix hosts.
5805 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5806 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5807 AC_PROG_MKDIR_P from AS_MKDIR_P.
5808 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5809 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5810 earlier editions are not (including Automake 1.8.3).
5811 Do not suggest mkinstalldirs for thread-safety.
5812 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5813 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5814 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5815 presence of special characters and race conditions.
5816 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5817 in Autoconf's name space.
5819 2006-05-10 Bruno Haible <bruno@clisp.org>
5820 and Paul Eggert <eggert@cs.ucla.edu>
5822 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5823 from Automake with minor changes.
5824 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5826 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5828 * config/install-sh: Update to Automake CVS version, as follows:
5829 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5830 * lib/install-sh: Simplify the expr implementation of dirname.
5831 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5832 * lib/install-sh: Handle --, and diagnose unknown options.
5834 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5836 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5837 `./autom4te' to create `./testsuite', since the `all' target
5838 will ensure its presence, but `installcheck' should not create
5839 the uninstalled wrappers.
5841 * tests/torture.at (Unusual Automake input files): Skip if we
5842 detect automake < 1.8.
5844 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5846 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5847 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5848 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5851 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5853 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5854 munge (multiple) white space and other oddities.
5855 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5856 single quotes in variable assignment.
5857 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5858 and similar failures by adding multiple spaces, tabs, and other
5860 Report and different test suggested by Francesco Romani
5861 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5863 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5864 single quotes, we only need to search for single quotes; this
5865 both simplifies the search pattern, and makes us less
5866 susceptible to `echo' variations for arguments not containing
5868 (_AC_ARG_VAR_VALIDATE): Likewise.
5870 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5872 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5873 `$*' and IFS concatenation issue with traditional shells and
5874 bash-2.04. Report by Seanster@Seanster.com.
5876 2006-05-03 Bruno Haible <bruno@clisp.org>
5878 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5879 precisely which Mac OS X versions have the od problem.
5881 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5883 * doc/autoconf.texi: Use @option systematically.
5885 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5886 and Bruno Haible <bruno@clisp.org>
5888 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5890 (Integer Overflow): Mention the special case of integer division
5893 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5895 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5896 traditional shells like the Solaris one that do not use the
5897 first IFS character for assembling `$*'.
5898 Prompted by a related report from autoconf_bug@nro.ca.
5900 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5901 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5903 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5904 Mention more problems with the -e option.

5909 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5911 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5912 in URLs to improve DVI formatted output (requires texinfo 4.6).
5913 (System Services, Systemology, Shellology): Likewise.
5914 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5917 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5919 (Runtime): Fix macro argument names to match description:
5920 `action-if-found' -> `action-if-true' and similarly.
5921 (Obsolete Macros): Likewise.
5922 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5923 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5924 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5926 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5928 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5931 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5934 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5936 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5937 /bin/sh set unsorted output.

5944 (Integer Overflow, Null Pointers, Buffer Overruns):
5945 (Floating Point Portability, Exiting Portably): New sections.
5946 (Writing Test Programs): Fix some langauge. Recommend exiting
5947 with status 1, not merely nonzero. Clarify exit declaration.
5948 (Run Time): Move C exit status stuff to new Exiting Portably section.
5949 (Systemology): Mention Posix and levenez. Update v7 reference.
5950 (Portable Shell): Mention the Posix shell.
5952 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5954 * bin/autoconf.as (me): Replace by as_me.
5956 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5958 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5959 since as_me isn't set yet.
5961 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5963 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5964 a few minor bugs in this area.
5966 * doc/autoconf.texi (Programming in M4sh): Comment out the
5967 documentation of AS_BASENAME, for now.
5968 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5969 (Limitations of Builtins) <basename>: Do not refer to
5971 * bin/autoconf.as (me): Don't use AS_BASENAME.
5972 (dir): Remove the unused variable.
5973 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5974 AS_DETECT_REQUIRED. All uses changed.
5975 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5977 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5978 (AS_BASENAME): Use "basename --" to protect against leading "-".

5980 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5981 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5982 (_AS_DIRNAME_PREPARE): Likewise.
5983 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5984 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5985 (AS_DIRNAME): Use "dirname --".
5987 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5989 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5990 of "run time" and "run-time" changed to "runtime", for consistency.
5991 * lib/autoconf/fortran.m4: Likewise (in comment).
5992 * lib/autoconf/functions.m4: Likewise.
5993 * lib/autoconf/general.m4: Likewise.
5994 * lib/autoconf/headers.m4: Likewise.
5996 * doc/autoconf.texi (Run Time): Document the exit status situation
5997 with more accuracy and detail.
5999 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6001 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6002 Archive is not officially `GNU' any more. Update URL.
6003 (Defining Directories): Likewise
6004 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6006 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6008 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6009 newline from the `trap' code to finish `config.log'; the NetBSD
6010 /bin/sh resets the exit status after an empty command, as
6011 documented in doc/autoconf.texi.
6012 Reported by Dalibor Topic <robilad@kaffe.org>.
6014 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6016 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6017 Suggested by Bruno Haible.
6019 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6021 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6022 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6023 Instead, just list the shells that we know work.
6024 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6025 changed. Be more cautious about the _cv_ variable.
6026 * tests/tools.at (Syntax of the shell scripts): Check the
6027 _cv_ variable once, at first, to avoid an internal autoconf error
6028 when sh -n does not work.
6030 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6032 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6034 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6036 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6037 use ">&-" since we're only 99.999% sure that this is portable,
6038 and since the MinGW bug is fixed in a different way.
6039 * lib/autotest/general.m4 (AT_INIT): Likewise.
6041 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6043 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6044 before opening config.log, to avoid hitting a bug on MinGW.
6046 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6048 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6049 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6050 This works around a MinGW bug reported by Eric Paire.
6051 Make sure that all writes to the log file append to it,
6052 rather than possibly losing data.
6053 * lib/autotest/general.m4 (AT_INIT): Likewise.
6055 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6057 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6060 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6064 * configure.ac (AC_INIT): Bump to 2.59d.
6066 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6070 * Makefile.maint (news-date-check): Do not require a leading `*'
6071 before the release date in NEWS.
6073 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6074 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6076 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6077 the instantiated file do not contain the string 'datarootdir'
6078 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6079 @mandir@, replace the reference '${datarootdir}' by the value.
6080 * tests/torture.at (datarootdir workaround): New test.
6081 * NEWS: Advertise this temporary fixup.
6082 Based on a patch by Bruno Haible, reported and analyzed by
6083 Paul Eggert and Noah Misch.
6085 2006-04-12 Eric Blake <ebb9@byu.net>
6087 * tests/autotest.at (Debugging a failed test): Fix comment.
6089 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6091 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6092 all the changes since 2006-04-07.
6094 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6096 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6097 succeeded, but `ln -s file dir' failed, take care to remove the
6098 leftover target before the next test, to prevent its spurious
6099 failure; also make sure `ln file dir' works before selecting it.
6100 Thanks to Keith Marshall for pointing this out.
6103 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6104 assignments in `at_debug_args', so that we put them correctly
6105 in the `run' script.
6106 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6107 Reported by Eric Blake.
6109 2006-04-11 Eric Blake <ebb9@byu.net>
6111 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6112 top-level tests after micro-suite has been run. Used in...
6113 (Debugging a successful test, Debugging script and environment),
6114 (Debugging a failed test): ...these new tests. The first of these
6116 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6117 macro, split out from...
6118 (AT_INIT): ...here, so that using -d also generates a run script.
6119 Document that -d inhibits top-level logging.
6120 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6121 inhibits top-level logging; debug scripts are created.
6123 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6125 * tests/autotest.at (Empty test, Empty check): New test to check it.
6127 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6130 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6132 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6133 the files if a problem appears. Make the empty *.at files
6134 read-only, too. Proposed by Ralf Wildenhues.
6136 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6138 * config/Makefile.am: Add comment to force updated Makefile.in.
6140 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6141 space only patch to this file, this patch causes the Makefile.in
6142 files that include freeze.mk to be updated, and thus have a
6143 newer time stamp again, which in turn makes a pristine CVS
6144 checkout have correct time stamps.
6146 * Makefile.maint (cvs-sv): New macro, to be used..
6147 (config.guess-url_prefix, config.sub-url_prefix)
6148 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6149 point to CVS text checkout of Gnulib files.
6150 (copyright-check): Bump current year.
6151 (announcement): Do not hard-wire `./announce-gen'.
6152 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6154 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6156 (wget_files): Update config.guess, config.sub, texinfo.tex by
6157 `wget-update', now that their URLs work again.
6159 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6161 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6162 Problem noted by Paul D. Smith.
6164 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6166 * doc/autoconf.texi: Remove unused words from word list.
6167 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6168 .x-sc_trailing_space: New files.
6170 * doc/standards.texi: Sync from gnulib.
6172 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6173 `LIBOBJDIR' as experimental.
6175 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6176 with a target directory; it's internally implemented as `cp'
6177 anyway, but since Autoconf advertises the possibility to use
6178 a target directory when LN_S is `ln -s', we need to find out.
6179 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6180 analyzed by Keith Marshall <keith.marshall@total.com>.
6184 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6186 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6187 confdefs.h as-is. In general, if it has backslash-newline or the
6188 like, then it doesn't work either to sort or to remove empty
6191 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6193 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6195 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6197 * lib/autom4te.in (Automake-preselections): Preselect
6200 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6202 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6203 apostrophe within a single-quoted string, as this is the usual
6204 tradition and is easier to read than '"'"'. Don't rely on the
6205 shell treating "$/" like '$/'. Use a more-consistent indenting
6208 2006-04-09 Eric Blake <ebb9@byu.net>
6210 * tests/autotest.at (Backquote command substitution),
6211 (Multiline backquote command substitution): Remove mistaken
6212 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6214 (Parenthetical command substitution, Multiline parenthetical
6215 command substitution): here.
6217 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6219 Import macros from gnulib (often changing their name).
6221 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6222 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

6229 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6230 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6231 The manual mentions Gnulib more prominently.
6232 * doc/autoconf.texi (Gnulib): New node.
6233 (Pointers): Add Gnulib URL.
6234 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6235 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6237 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6238 suggest a #define rather than a typedef for _Bool, and mention
6239 Gnulib rather than trying to substitute stdbool code.
6240 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6241 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6242 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

6348 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6350 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6351 whether `set' quotes correctly: redirect stderr of the tested
6352 `set', and use a subshell, for Ultrix; use `sed' instead of
6353 `grep' for zsh `set' which may write binary output; match only
6354 at the beginning of a line, to avoid false positives.
6355 In order to avoid false positives by unrelated variables with
6356 multiline content, put the dump algorithm in a subshell and
6357 unset all variables containing newlines (except some which are
6358 special to the shell). Warn about cache variables that are

6404 ac_config_<foo>s again, sometimes normalized, sometimes not.
6405 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

6407 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6408 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

6419 for --help from Cygnus `configure.'
6421 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6473 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6474 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

6565 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6566 initial `rm' of the candidate files...

6573 no longer needed) by libtool. Make it a cache check.

7351 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7352 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7353 by the function rather than ignoring it.
7354 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7355 comparing its address. Intel's interprocedural optimization was
7356 outsmarting the old heuristic. Problem reported by
7359 2005-10-19 Stepan Kasal <kasal@ucw.cz>

7368 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7370 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7371 before removing it (chmod -R u+rwx); there are three instances of this.

7374 Stepan Kasal <kasal@ucw.cz>
7376 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7377 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7378 make its content writable before removing it. Remove an errorneous
7379 comment from the end, where the logs of the failed tests are copied
7380 to the main log file.
7382 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7384 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7385 in case the computer is too quick. Double quote the configure.ac

7389 problems if the testsuite were running too fast.
7391 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7393 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7394 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7395 (which belong to Xt, not X itself). See Debian bug 327655.
7396 * NEWS: Mention this.
7398 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7400 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.

7404 * config/move-if-change: Don't output "$2 is unchanged";
7405 suggested by Ben Elliston. Handle weird characters correctly.
7407 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7409 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7410 calls, so that the final expansion of this macro is shorter.
7411 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7412 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7413 the cleanup there. Use AS_VAR_* macros, to be more general.
7414 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7416 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7418 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7420 2005-09-01 Stepan Kasal <kasal@ucw.cz>

7433 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7434 The previous patch didn't work, so try a better one.
7436 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7438 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7439 in the example. Reported by Bruno Haible.
7440 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7441 "if $undefined_var;" succeeds with my shell.
7443 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7444 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7445 but change the m4_divert_text to m4_divert_once.
7447 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7449 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7450 Work around bug in Solaris /usr/xpg4/bin/awk.
7451 The bug is present in at least Solaris 8 through 10.
7453 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7455 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7456 some evil values and relying on the fact that $* concatenates the
7457 parameters by the first character from IFS.
7459 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7460 Stepan Kasal <kasal@ucw.cz>
7462 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7463 first header appears, define AH_HEADER.
7464 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7465 Update limitations about when to call AC_CONFIG_HEADERS.
7466 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7467 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7468 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7469 ``Configuration Actions''; fix their index entries.
7471 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7472 options correctly. Process N-M as M-N if M is smaller than N.
7473 Process ranges correctly so that N-N will run only N.
7474 Sort and uniquify the tests that will be run. If there is more
7475 than one test, reinsert the banners for the tests.
7476 * tests/autotest.at (Keywords): Unmark XFAIL.
7478 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7480 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7481 before passing the macro name to AH_TEMPLATE.
7483 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7484 now opens log after option processing; in particular, --version
7485 and --help do not touch config.log.
7487 * Makefile.maint: Revert the change from 2005-08-12.
7489 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7491 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

7495 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7497 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7498 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7501 * doc/autoconf.texi (Defining Symbols, Changed Results):
7502 Prepend to LIBS, not append, in examples.
7504 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7506 When building in place, set srcdir="."; suggested by Tim Van Holder.
7508 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7509 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7510 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7511 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7512 does not mean "no --srcdir option".
7514 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7516 * tests/autoscan.at (autoscan): New file.
7517 * tests/suite.at: Use it.
7518 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7519 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7521 * tests/autotest.at (Keywords): Test keywords combinations.
7523 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7525 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7526 add "2>&1"; gzip 1.2.4 prints help on stderr.
7528 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7530 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7531 was pushdef'ed twice while popped only once. Push it only once.
7532 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7534 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7536 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7537 prefixed by mere "===", not "configure: === ".
7539 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7541 * Makefile.maint: Update from Bison.
7543 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7544 "<tab>" in comment, so that the point is understandable.
7546 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7548 Rewrite substantial part of lib/autoconf/status.m4.
7549 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7550 and CONFIG_COMMANDS are not processed in four separate loops.
7551 Instead, there is one main loop. This alows that the common code
7552 is expanded only once, thus config.status (and configure) is smaller.
7554 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7555 the AC_LIST_FILES and cousins macros are no longer used.
7557 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7558 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7559 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7560 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7561 contain the initialization, nor the for loop, nor the associated
7562 commands; all these go to ...
7563 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7564 _AC_OUTPUT_CONFIG_STATUS.
7565 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7566 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7567 (_AC_OUTPUT_FILE): The creation of the sed script ...
7568 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7569 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7570 _AC_OUTPUT_MAIN_LOOP.
7571 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7572 _AC_CONFIG_COMMANDS): Use ...
7573 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7574 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7575 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7576 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7577 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7578 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7580 (_AC_CONFIG_UNIQUE): Update.
7581 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7582 Replaced by this ...
7583 (_AC_LIST_TAGS): ... new common macro.
7584 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7585 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7586 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7587 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7588 this didn't belong to the `config commands' section.
7589 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7590 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7591 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7592 to the `config commands' section either.
7593 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7594 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7596 ... and many changes to the comments nearby.
7598 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7599 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7600 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7601 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7602 (#define header templates): The comment at the top of the generated
7603 header now includes the name(s) of the source file(s).
7605 Several unrelated small changes:
7607 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7608 parameter to AC_DIAGNOSE.
7609 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7610 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7611 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7612 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7614 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7615 in AC_OUTPUT doesn't double-quote it either.
7616 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7619 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7621 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7622 versions of Portland Group compiler produce single- and double-quoted
7623 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7624 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7626 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7628 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7629 This is a corrected version of yesterday's patch.
7631 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7633 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7634 path, too; insert a "===" to emphasize the line.
7636 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7637 ac_cv_build_alias to ac_build_alias.
7638 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7640 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7641 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7642 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7643 (AC_ARG_VAR): ... here.
7644 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7647 Keep a list of all precious variables and process them with one simple
7648 for loop, instead of expanding all commands, or, OTOH, complicated
7649 processing of output of "set".

7711 configure_input, top_builddir, srcdir, etc.
7712 * lib/autotest/general.m4 (AT_INIT): Likewise, for

7784 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7805 variable into diagnostic. Make the diagnostic an error, not a warning,
7806 because we really don't support spaces and suchlike in dir names.
7807 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7808 Don't worry about backslashes in srcdir; it can't happen now.

7852 * doc/autoconf.texi:
7853 Don't mention Solaris versions so much, if a
7854 problem is common to all extant versions of Solaris. Say "SunOS
7855 4" instead of "SunOS" for SunOS 4.
7856 (awk): Mention more of the limitations of traditional Awk.

7899 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7900 -u, since it outputs chatter if the input files are the same.
7901 Problem reported by Ralf Menzel.
7903 2005-06-08 Derek Price <derek@ximbiot.com>
7905 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7906 renaming them since they are about to be redefined anyhow.
7908 2005-06-08 Derek Price <derek@ximbiot.com>
7910 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7911 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7912 Move m4_undefine to alphabetical order.

7917 * doc/autoconf.texi (Introduction): Likewise.
7918 Reword to avoid some formatting glitches.
7919 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7920 Clarify explanation of HP compiler bug.
7921 Redo example output tp match current CVS snapshot.
7922 Use @example.org in email addresses when the examples
7923 might get inadvertently cut-and-pasted into user code.
7924 Remove example of autom4te usage that doesn't seem to work now.
7925 Use modern AC_INIT (except when the example is meant to be
7926 shown with Autoconf 2.13).
7927 Update ksh info for Solaris 9 and later.
7929 Modernize description of Automake versions a bit.
7930 Don't claim a future version of Autoconf is near.

7940 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7941 Tru64 ksh pattern matching bug. Reported against Libtool by
7942 Albert Chin <libtool@mlists.thewrittenword.com> and
7943 Nicolas Joly <njoly@pasteur.fr>.
7945 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7947 m4_cdr of one-member list was [[]] (one-member list containing an
7948 empty string) instead of [] (an empty list. Callers were skewed to
7949 match this misbehaviour. As a consequence of this:
7950 - m4_foreach([x], [], [foo]) expanded to `foo', while
7951 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7952 This bug has been fixed:
7954 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7955 expand to an empty string; print error msg if called without
7957 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7958 misbehaviour; handle [] and [[]] correctly.

7968 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7969 swallow records with more than 99 fields.
7970 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7971 parse the long line.
7973 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7975 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7976 swallow literals longer than 399. Reported by Ralf Wildenhues.

7988 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

8010 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may

8015 commands can be put in a sed script portably.

8170 * doc/autoconf.texi (Autoconf Language): Be more precise about
8171 quoting rules. Problems noted by Stepan Kasal.
8172 Also, throughout this document, be more careful about white space.
8173 "blank", "white space", and "space" all have different meanings
8174 and we should be careful to say what we mean.

8178 Fix C++ related problems reported by Werner Lemberg.
8179 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

8185 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8187 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8189 * doc/autoconf.texi (Generic Functions): Typos.
8191 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8193 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8194 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8195 set by latest automake.
8197 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8199 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8200 outputs 0 on GNU/Linux these days.
8202 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8204 * doc/autoconf.texi (Autoconf Language): Add more description

8208 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8210 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8213 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8214 by AC_DEFINE; it was a mistake.
8215 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8217 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8219 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8221 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8223 * doc/autoconf.texi (External Software): Quadrigraphs are not
8224 processed correctly in AS_HELP_STRING; avoid this in the examples.
8225 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8226 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8227 comment and reduce m4_default([foo], []) to [foo].
8228 (m4_strip): Update the explanation.
8230 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8232 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8233 Remove core.conftest.* too; it's generated by Tru64 5.1.
8234 Problem reported by Jennis Pruett.
8235 * lib/autoconf/functions.m4
8236 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8237 Don't bother to remove core files; AC_RUN_IFELSE should do that
8240 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8242 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8259 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8261 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8262 as well as configure.in. Problem reported by Gregorio Guidi.
8264 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8266 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8267 pattern for alloca snippet.

8282 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8284 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8285 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8286 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8287 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8288 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8290 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8292 * NEWS: The configure command now warns you if you attempt to use
8293 a directory whose name contains a special character like space,
8295 * doc/autoconf.texi (Installation Directory Variables): Allow
8296 "," in file names. Do not use \@; it's not a portable regexp.
8297 * bin/Makefile.am (edit): Likewise.
8298 * lib/Makefile.am (edit): Likewise.
8299 * tests/Makefile.am (edit): Likewise.
8300 * tests/semantics.at: Likewise.
8301 * tests/torture.at: Likewise.
8302 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8303 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8304 * doc/autoconf.texi (File System Conventions): Warn about
8305 unportable file names.
8306 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8308 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8309 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8310 ac_pwd, and quote srcdir.
8311 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8313 * doc/autoconf.texi: Fix some systematic formatting problems.
8314 ".)" needs a following @: if not at the end of a sentence, and
8315 similarly for "!)". "etc." should be preceded by a comma.
8316 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8318 2005-03-22 Bruno Haible <bruno@clisp.org>
8320 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8321 argument is often called 'build-aux'.
8323 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8325 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8326 macro AC_TRY_LINK is obsolete.
8327 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8330 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8332 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8333 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8334 from a Common Lisp's `cl'.
8335 (AC_PROG_CXX): Behave according to the documentation: don't
8336 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8337 make the variable CCC precious; use `cl.exe', not `cl'.
8339 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8340 Alexandre Duret-Lutz <adl@gnu.org>
8342 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8343 /dev/null, as "configure" shouldn't read stdin, and this insulates
8344 us from problems (e.g., when testing for "cl"). Also, do this
8345 redirection before invoking "hostname" or "uname", and keep the
8346 original input stream available via...
8347 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8348 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8349 bother with "</dev/null" since it's now done at the top of
8351 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8352 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8353 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8354 * doc/autoconf.texi (File Descriptor Macros): New section.

8356 * tests/base.at (Input/Output): New test.
8358 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8360 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8361 newline if neither \c nor -n work, as that would output two
8362 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8364 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8366 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8367 This causes that any required macros inside will get before the if.
8368 * doc/autoconf.texi (autom4te.cache): A typo.
8370 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8372 Undo previous change, except keep the change to
8373 lib/autoconf/programs.m4 that replaced grep with shell
8374 pattern-matching. This is because net-snmp configure reads stdin.
8375 Reported by Noah Misch.
8377 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8379 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8380 from /dev/null, as "configure" shouldn't read stdin, and this
8381 insulates us from problems (e.g., when testing for "cl").
8382 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8383 before invoking "hostname" or "uname".
8384 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8385 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8386 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8387 "</dev/null" since it's now done at the top of 'configure'.
8388 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8389 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8390 Also, replace grep with shell pattern-matching, to save a process.
8392 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8394 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8395 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8396 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8399 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8401 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8402 grep -q isn't portable. Improve grep -s explanation.
8403 Problem reported by Dan Manthey.
8405 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8407 * doc/autoconf.texi (Special Shell Variables): Clarify
8408 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8410 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8412 * doc/autoconf.texi: Use @acronym for DJGPP.
8413 Fix some @code's that should have been @env's, and vice versa.
8414 Sort environment variable names.
8415 Mention that shells no longer inherit IFS.
8416 Don't recommend PATH_SEPARATOR=';' so strongly.
8417 Mention that $RANDOM might expand to the empty string.
8418 "symlink" and "soft link" -> "symbolic link".
8419 Improve mktemp description (reported by Bruno Haible).
8421 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8423 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8424 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8426 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8429 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8431 * NEWS: Mention AT_COPYRIGHT.
8433 * tests/local.at (AT_CMP): Use diff directly on input files rather
8436 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8437 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8439 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8440 and Paul Eggert <eggert@cs.ucla.edu>
8442 * tests/autotest.at (Empty test suite): New test.
8443 * tests/torture.at (Substitute and define special characters)
8444 (Substitute a 2000-byte string, Define to a 2000-byte string)
8445 (Substitute a newline, Define a newline): New tests.
8447 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8449 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8450 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8451 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8452 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8453 (Standard regular expressions): New test.
8454 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8455 excess test name quoting.
8456 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8457 CPPFLAGS to `configure' instead of setting it in `configure'.
8459 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8460 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8463 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8464 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

8469 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8470 (AT_CONFIG_CMP): New macro.
8471 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8472 * tests/c.at (Extensions): Do not exit early.
8473 * tests/atlocal.in: Inherit $GREP.
8475 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8476 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8478 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8479 (AC_COPYRIGHT): Factor header comment portion out and move into...
8480 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8481 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8482 (AT_INIT): Add Autotest copyright notice. Display copyright notices in

8492 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8494 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8495 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8497 Try not to generated lines of unlimited length, as POSIX places a
8498 2047-byte limit on line length of portable text files.
8499 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8500 Use newline as a separator, not space.

8505 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8507 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8508 as_func_*. Add test to check whether positional parameters
8509 are restored after function return.
8511 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8513 * doc/autoconf.texi (Special Shell Variables): Mention _,
8514 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8515 if they contain a lower-case letter. The DUALCASE problem was
8516 reported by Ralf Wildenhues.
8518 * bin/autoconf.as: Don't exit with status 0 after write failure
8519 with --help or --version.
8520 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
8521 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

8525 * doc/autoconf.texi (Limitations of Usual Tools):
8526 Unicos 9 sed limitations.
8527 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
8528 to get the option-enhanced interface on older Crays. Try ftn for
8529 Fortran 95 (newer Crays).
8531 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8533 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8534 care to echo the commands, so the user knows what's going on.
8535 Modified from a suggestion by Stepan Kasal.
8537 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
8538 with a cross reference. Derived from a suggestion by Bruce Korb.
8540 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
8542 * doc/autoconf.texi (config.status Invocation): Warn about
8543 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
8544 * doc/install.texi (Defining Variables): Likewise.
8545 Based on a proposed patch by Ralf Wildenhues.
8547 * man/Makefile.am (.x.1): Make sure the required generated files
8548 are up to date. Problem and original solution proposed by Stepan Kasal.
8549 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
8550 implicit-man-prerequisites): New rules, used by the above.
8552 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
8553 * config/config.guess, config/config.sub, config/install-sh: Likewise.

8558 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8559 Update the long comment explaining it.
8561 m4_require no longer writes an ``is required by'' line to the
8562 execution stack. It contains only one bit of non-redundant
8563 information: that the macro was required, not called. And even
8564 this bit is useless in most situations: have you ever met a macro
8565 which both calls and requires the same macro?
8567 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8568 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8571 (m4_expansion_stack_pop): Remove the misplaced comment.
8572 (m4_require): Don't put the ``is required by'' line to the
8573 execution stack; slightly improve the out-of-a-defun error message.
8574 (_m4_divert_grow): New macro, counter for the temporary diversions.
8575 (_m4_require_call): Use it.
8576 * tests/m4sugar.at (m4_require): Expect output without the
8577 ``is required by'' messages.
8579 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

8616 Warn about newline stripping in `` and $(). Update Solaris
8618 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8619 X insulates us from future changes to Posix.

8673 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8674 stored in _m4_divert_diversion or _m4_divert_dump.
8675 (m4_divert_pop): When the parameter is given, compare the symbolic
8676 name with the last diversion pushed on the stack. Previously, the
8677 current diversion was compared with the numeric value of the
8678 diversion given as the parameter.
8679 (m4_require): If the macro hasn't been expanded yet, call ...
8680 (_m4_require_call): this new macro.

8985 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8987 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8988 "char c = '\200';" rather than "char c = 0x80;" as the
8989 latter doesn't conform to the strict C standard due to
8990 overflow on signed char hosts.
8992 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8993 to -qlanglvl=ansi. We don't want to disable extensions.
8995 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

9049 simplify the examples and improve their quoting.
9051 2004-11-13 Stepan Kasal <kasal@ucw.cz>
9053 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9054 the $1_found variable, don't test whether the file is executable;
9055 Both things are checked ...
9056 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
9057 the former ``test -f''.

9072 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9073 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9074 variants", "Unix", and some related minor wording fixups.
9076 (Shellology, Special Shell Variables): Document that the Zsh
9077 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9078 to Alexandre Duret-Lutz for this info.

9087 of putenv. Problem reported by Michael Wardle.
9089 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9091 * doc/autoconf.texi (auindex): New macro.
9092 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9093 Problem reported by Stepan Kasal.

9099 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9101 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9102 readable; it's not true in OS/2-emx.
9104 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9106 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9107 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9108 (trivial change). Problem and patch reported by Andrew Church in:
9109 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9111 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

9138 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9139 texinfo.tex for now (done by hand now).
9140 * Makefile.maint (wget_files, cvs_files):
9141 Remove ansi2knr.c; nobody uses it.
9142 (ansi2knr.c-url_prefix): Remove.
9143 (cvs-update): Fix test for failure. I don't know why it ever
9146 * doc/autoconf.texi: Update URLs, some of which went stale.
9147 Use @uref rather than @href.
9149 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9150 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9152 * config/config.guess, config/config.sub, config/elisp-comp,
9153 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9154 doc/fdl.texi, doc/standards.texi: Sync with master copy.

9162 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9163 tests/tools.at, tests/torture.at:
9164 Use "file name" rather than "filename" or "path",
9165 to be consistent with the terminology of the GNU coding standards.
9167 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9169 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9170 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9171 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9172 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9174 More fixes to support spaces in the name of the build directory.
9175 This isn't a complete fix but it's an improvement.
9177 * bin/autoconf.as (autom4te_options): New var.
9178 Use it instead of appending to AUTOM4TE, so that we can allow
9179 spaces in the build directory's absolute name.
9180 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9181 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9182 AT_CHECK_NOESCAPE): Likewise.
9183 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9184 main program): Likewise.
9186 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9188 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

9194 * doc/autoconf.texi (Function Portability): Document isinf and
9195 and isnan. From a suggestion by Kevin Ryde.
9197 * lib/Autom4te/General.pm (END): Return correct exit status even
9198 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9200 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9202 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9203 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9204 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9206 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9208 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9209 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9210 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9211 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9212 * lib/autom4te.in (Automake-preselections): Preselect
9213 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9215 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9217 * lib/autom4te.in (Automake-preselections): Preselect
9218 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9221 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

9226 Document problem with "`""`" in pdksh POSIX mode.
9228 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9230 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9231 with pdksh, too. Problem reported by Patrick Welche via
9233 * doc/autoconf.texi (Shellology): Note that set -o posix is
9234 useful for pkdsh, too.
9236 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9238 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9239 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9240 Don't fail if ENV or BASH_ENV is readonly.
9241 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9242 etc. are read only. Problem reported by Ludovic Courtes.
9244 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9246 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9247 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9250 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9252 * doc/autoconf.texi (File System Conventions): Warn about
9253 names like "aux". Problem reported by Eric Blake.
9255 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9256 by zero instead of array size, so that we can use any arithmetic
9257 constant expression (instead of requiring an integer constant
9258 expression). This allows us to test expressions like DBL_MAX <
9259 LDBL_MAX, which didn't conform to the C standard using the old
9261 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9262 now that we can do floating-point tests at compile time.
9264 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9266 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9267 and LDBL_EPSILON, as the resulting expression isn't an
9268 integer constant expression and violates the C standard.
9269 Problem reported by Nelson H. F. Beebe. Also, check
9270 for "L" suffix, and check that long double doesn't have
9271 worse range or precision than double, that mixed-mode
9272 arithmetic doesn't generate a diagnostic, that double
9273 constants fit in long double.
9275 2004-06-03 Kevin Ryde <user42@zip.com.au>
9277 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9278 malloc(0) and realloc(NULL,size).
9280 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9283 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9285 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9286 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9289 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9291 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9292 can be rewritten using if-then-else. Suggested by Bruno Haible.
9294 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9296 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9297 Problem reported by Stepan Kasal.
9299 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9301 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9302 change). Patch reported by Ralf Wildenhues in
9303 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9305 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9306 function F exists if the compiler and linker let you compile an
9307 expression like (F != 0). Recent versions of GCC optimize away
9308 the reference to F in that case, since every function address must
9309 be nonzero, so the link succeeds even if F does not exist.
9310 Problem reported by Manu in
9311 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9313 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9314 "Unix". Many uses changed.
9315 (Limitations of Builtins): Explain better why the ! command isn't
9318 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9320 * lib/autom4te.in (Automake-preselections): Preselect
9321 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9323 2004-05-19 Kevin Ryde <user42@zip.com.au>
9325 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9326 referencing AC_FUNC_STRERROR_R.
9328 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9329 note pessimistic assumption when cross compiling.
9331 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9333 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9334 (until 2004) invoked subcommands with sh -e, contra POSIX.
9335 Reported by Kevin Ryde.
9337 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9339 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9340 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9341 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9342 `test -f " /usr/bin/grep"', which _always_ failed.
9343 (AC_PROG_SED): Ditto bogus PATH fix.
9344 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9345 requires that grep correctly supports _multiple_ `-e' options, rather
9346 than stating only that grep should accept `-e'.
9348 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9350 Port to C99, which requires that 'exit' be declared.
9352 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9353 to ensure that stdlib.h is included.
9354 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9355 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9356 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9357 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9358 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9359 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9360 when using 'exit' in a test; C99 requires that 'exit' be declared.
9362 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9364 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9365 now prefers 'grep' implementations that accept -e.
9366 (Limitations of Usual Tools): Describe problems of traditional
9367 egrep and fgrep with long input lines, and of traditional grep
9369 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9370 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9371 All callers changed. Append /usr/xpg4/bin to the PATH, for
9373 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9374 the user with complaints about multiple -e options.
9375 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9376 Define it with AC_PROG_GREP.
9377 * configure.ac (AC_PROG_GREP): Add.
9378 * lib/freeze.mk (GREP): New macro.
9380 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9382 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9383 a possible candidate only after all others fail, rather than
9384 consulting it first. This improves backward compatibility by
9385 better reflecting the way shell selection occurred in previous
9386 versions of Autoconf, and should help to avoid triggering latent
9387 problems in other packages, such as the one in Automake where zsh
9388 is not handled robustly:
9389 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9390 Although it is not Autoconf's responsibility to work around
9391 problems in Automake, it nevertheless makes sense to avoid
9392 introducing unnecessary incompatibilites.
9394 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9395 Gary V. Vaughan <gary@gnu.org>
9397 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9398 how deeply nested we are when a suitable tool is found, set the
9399 ac_path_TOOL_found flag.
9400 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9401 nested we are in this macro. Break out of all 3 nested loops if
9402 ac_path_TOOL_found is set.
9404 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9406 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9407 of the _AS_PATH_WALK loop too if GNU flavor is found.
9409 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9411 * doc/autoconf.texi (Limitations of Make): Update documentation
9412 for `$<'. New entry `Long lines', based on a report from Simon
9413 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9414 paragraph about DJGPP, based on a mail from Richard Dawe.
9416 2004-04-20 Paul Eggert <eggert@twinsun.com>
9418 * tests/c.at (C keywords): Don't assume that GCC supports
9419 "restrict" and "inline", as sufficiently-old GCC versions do not
9420 (also, GCC configured to be in pedantic C89 mode does not).
9421 Problem reported by Sumit Pandya in:
9422 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9424 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9425 consider -g to work if it generates warnings when plain compiles
9426 don't. Problem reported by Braden McDaniel in:
9427 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9429 * doc/autoconf.texi (Slashes): New section, to document a problem
9430 reported by Jim Meyering in:
9431 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9433 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9434 linker output files before linking, to work around IRIX 6 linker bug.
9435 Problem reported by Rainer Orth in:
9436 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9438 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9440 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9441 best tool so far counter rely on the tool path variable name to
9442 avoid checks for one tool being affected by the results of running
9443 the length check on a previous tool.
9445 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9446 match expression argument, as different greps have different
9447 regular expression flavours.
9448 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9450 (AC_PROG_EGREP): Pass 'EGREP$'.
9451 (AC_PROG_GREP): Pass 'GREP$'.
9453 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9455 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9456 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9458 2004-03-29 Paul Eggert <eggert@twinsun.com>
9460 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9461 Types, Specific Compiler Characteristics, System Services,
9462 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9463 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9464 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9465 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9467 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9468 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9469 AC_TYPE_OFF_T): Likewise.
9470 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9473 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9474 pacify libtool 1.5.2. Fix quoting problems in sed command.
9476 2004-03-28 Paul Eggert <eggert@twinsun.com>
9478 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE

9583 AC_SUBST provides no portable way to escape literal newlines.
9585 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9586 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.

9613 Eric Sunshine <sunshine@sunshineco.com>

9664 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9665 2003 (except 1997) to the list of copyright years. This undoes
9666 the 2003-05-22 change, which removed the older years from the list.

9680 _AC_PROG_GREP, and AC_PROG_SED.

9713 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9714 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9715 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9716 not <inttypes.h>. Problem reported by Tim Mooney in

9718 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9721 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9722 otherwise "make check" fails because it forbids cmp (I guess
9723 because cmp treats files as binary on DOS-like systems).

9738 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9739 -std1 disables some useful extensions on Tru64. Problem reported

9743 2004-01-14 Paul Eggert <eggert@twinsun.com>
9745 * doc/autoconf.texi (Programming in M4sh): Document that
9746 AS_MKDIR_P succeeds if the destination is a symbolic link
9747 to an existing directory.
9748 (Limitations of Usual Tools): Note that mkdir -p might not
9749 succeed on symlinks to directories.

9753 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9769 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9770 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9771 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9772 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9773 AC_COMPILE_IFELSE, since we now assume our caller invokes
9774 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9775 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9776 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9777 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9779 2004-01-07 Paul Eggert <eggert@twinsun.com>
9781 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9782 `"'...'"`, as it's confusing (and I suspect it may not work on
9783 some platforms). The code was incorrect anyway, as it assumed
9784 that \$ evaluated to itself in that context. Reported by
9785 Alexandre Duret-Lutz.
9787 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9789 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9819 Bug reported by David Relson in
9820 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9822 * Makefile.am (autom4te-update):
9823 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9839 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9840 -c -o might not work. From a suggestion by Kevin Ryde.
9841 (C Compiler, Generating Sources, Limitations
9842 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9843 Don't put '-o' after non-options, as POSIX doesn't allow this.

9855 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9857 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9858 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

10145 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10146 -mGLOB_options_string stuff for Intel ifc, which can cause

10170 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10171 cache variable instead of $G77 to decide whether to include -O2,
10172 since $G77 is specific to Fortran 77.

10176 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10177 free" flag. Re-order flags tested into rough order of popularity.
10179 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10181 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10182 arguments so that it can be used with syntax identical to
10183 AC_PROG_F77, and so that we can more easily decide to
10184 remove/deprecate the DIALECT optional argument in the future if it
10185 proves troublesome.
10186 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10187 non-freeform-supporting compilers. Document freeform flags.
10189 2003-10-03 Akim Demaille <akim@epita.fr>

10251 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10252 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10253 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

10258 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10259 directory for AC_CONFIG_COMMANDS' first argument exists.
10260 This makes valid the invocation of _AC_SRCPATH that follows.
10261 Reported by Eric Sunshine.

10285 The test suite are sometimes assigning timings incorrectly.
10286 Reported by Henk Krus.
10287 Diagnosed by Nicolas Joly.
10289 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10291 Instead of making AT_help a sequence of assignments to grow
10292 $at_help_all, just make AT_help_all be the growing contents of
10293 $at_help_all, and make a single assignment in...
10295 (at_times_skip): Flip the meaning and rename as...
10296 (at_times_p): this.
10297 (AT_INIT): When summarizing the test that ran, remove

10307 (ifnames): chmod -w.
10308 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10309 executables, not bin/ executables! Otherwise all the magic needed
10310 to find non installed files is turned off. This caused a failure
10311 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10312 as found in its environment (sent by tests/autoreconf): pointing
10313 to bin/autom4te that could not find its files.
10314 * tests/mktests.sh: Force the replacement of generated files, for
10315 the sake of "mv" program that are interactive when overwriting a
10317 * config/install-sh: Upgrade from CVS Automake.

10324 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10325 Paul Eggert <eggert@twinsun.com>
10327 Trivial change to support GCC's configuration procedure.

10363 willing to edit the output files.
10365 2003-09-10 Akim Demaille <akim@epita.fr>
10367 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10368 and AC_FC_FREEFORM.
10369 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10370 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

10410 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10412 Add support for newer Fortran dialects. The F77 interface is
10413 unchanged, and continues to support Fortran 77. New FC macros
10414 correspond to all the old F77 macros, with output variables FC,
10415 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10416 available dialect, but older dialects can be specified. There are
10417 new macros AC_FC_SRCEXT to set the source extension, and
10418 AC_FC_FREEFORM to accept free-form source files.
10420 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

10544 2003-08-21 Akim Demaille <akim@epita.fr>
10546 First stab at preserving warnings between calls to autom4te,
10547 including when the cache is used.
10549 There are still several issues: (i) there are too many runs of m4
10550 (one for include, one for warnings, and some more), (ii) warnings
10551 spreading on several lines are not handled gracefully, (iii) the
10552 code meant to have the call stack display for errors does not work
10553 (its handling should move from m4 to autom4te).
10555 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10557 (@preselect): Add m4_warn.
10558 ($exit_status): Remove, use $exit_code.
10559 ($help): Use Autom4te::ChannelDefs::usage.
10560 (&handle_m4): No longer define the m4_warnings.
10561 At each run, extract and report the warnings.
10562 Always cache the result, including if the exit status is on
10563 failure, since if nothing changes, we should result in the same
10564 failure, hence we can use the cache.
10565 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10566 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10568 (m4_warn): Redefine as a do-nothing: it is its invocation that
10569 matters, as warnings are now reported via traces.
10570 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10571 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10572 the latter reveals calls to the former.
10576 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

10605 Reported by Alexandre Duret-Lutz.

10609 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10610 * bin/autom4te: Adjust.
10611 In particular, be Autoconf tools are really silent when properly
10612 working, bind the verbosity of the 'note' channel to $verbose.
10613 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

10737 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10738 not all of them. This fixes 1. the fact that when testing
10739 Autoconf there are many many config.log, 2. the incorrect use of
10740 top_srcdir to find config.log.
10741 Don't mix the detailed output of failed test with the summary of
10742 failures. Rather, append detailed log afterwards.
10744 2003-06-23 Akim Demaille <akim@epita.fr>
10746 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10861 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10862 Remove `#include <stdlib.h>' from the list; we should never
10863 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10864 resulting namespace pollution would cause other tests to fail.
10865 Configure scripts run with some older versions of g++ and HP's
10866 aCC would fail due to such an #include. Problems reported by
10867 Matthew Mueller in <http://bugs.debian.org/120704> and by
10869 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10870 In the test, use the test declaration before including <stdlib.h>,
10871 as that's closer to how it'll be used.

10875 * doc/autoconf.texi (Header Portability): ucred.h.
10878 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10880 Overhaul Autotest's logging: generate separate log files
10881 in testsuite.dir/NNN/testsuite.log, and append them to
10882 testsuite.log instead of re-running the test verbosely.
10884 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10885 file descriptor, write 0 to at_status_file instead of setting
10886 at_status=0, initialize some new variables (at_status_file,
10887 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10888 to rerun the tests, instead append the at_group_log to the
10889 at_suite_log when a test fails.
10890 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10891 with the AS_MESSAGE_LOG_FD redirected to stdout.
10892 (AT_CLEANUP): save the output status in $at_status_file
10893 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10894 its original place.
10895 (AT_CHECK): since tests are run with a redirected stdout,
10896 and used to be re-run in verbose mode, turn some $at_verbose
10897 into echo, and don't redirect the output of testing stdout
10900 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10901 the name of the debugging directory and information about

11024 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11025 by aclocal.m4 is changed it might require the importing of another
11026 m4 extension file, i.e., aclocal must be run.

11299 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11300 defined, to support freestanding compilers. This should fix the
11301 bug reported by Momchil Velkov in

11304 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

11340 * Makefile.maint: Sync with Bison, i.e.:
11341 (po-check): Scan .l and .y files instead of the

11404 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11406 We _have_ to stop using the old compatibility scheme that tried to
11407 avoid useless backslashes because Libtool 1.4.3 contains a
11408 AC_DEFINE([error_t], [int],
11409 [Define to a type to use for \`error_t' if it is not
11410 otherwise available.])
11411 We _have_ to quote the single quote and backslashes with \. The
11412 old compatibility scheme saw that ` was backslashed, and therefore
11413 did not quote the single quote. Hence before this patch, Autoconf
11414 was not compatible with Libtool.

11805 Reported by Alexandre Duret-Lutz.
11807 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11868 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11869 aclocal invocation, as Gettext macros might not be visible to

11903 2002-09-28 Akim Demaille <akim@epita.fr>
11905 * tests/torture.at (Configuring subdirectories): Be robust to
11906 users who use config.site to require for a cache: in this case,
11907 the two last configure runs, using two different sets of
11908 arguments, trigger a legitimate error.
11910 2002-09-28 Akim Demaille <akim@epita.fr>
11912 * tests/m4sh.at (Functions Support, Functions and return Support):
11915 2002-09-28 Akim Demaille <akim@epita.fr>
11917 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11918 autoheader are Perl programs.
11919 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11920 (autom4te): Specify that the sources are in the $srcdir.

11928 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11929 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11930 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

11941 that were listed in the original autoscan.list.
11942 * lib/autoconf/headers.m4: Similarly with headers.
11943 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11944 (.m4.m4f): Don't pass --prepend-include, since that's done by
11945 tests/autom4te itself.
11946 * lib/autoscan/Makefile.am: Include freeze.mk.
11947 (autoscan.list): New target --this file is no longer a source.
11948 (autoscan.pre): New file.
11950 2002-09-28 Akim Demaille <akim@epita.fr>
11952 * bin/autoscan.in (@kinds): Make them singular.
11954 (&init_tables): When --debug, report the list of rules to ease
11955 tracking changes in autoscan.list.
11956 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11958 2002-09-28 Akim Demaille <akim@epita.fr>
11960 * lib/autoscan/functions, lib/autoscan/headers,
11961 * lib/autoscan/identifiers, lib/autoscan/makevars,
11962 * lib/autoscan/programs: Merge into...
11963 * lib/autoscan/autoscan.list: this.
11964 * bin/autoscan.in (&init_tables): Adjust.
11966 2002-09-28 Akim Demaille <akim@epita.fr>
11968 * lib/autoscan/functions, lib/autoscan/headers,
11969 * lib/autoscan/identifiers, lib/autoscan/makevars,
11970 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11971 `functions' line is now prefixed with `function:'.
11972 * bin/autoscan.in (&init_tables): Adjust.
11974 2002-09-28 Akim Demaille <akim@epita.fr>
11976 From now on, autoscan files must always map a macro name to a
11977 word: there is no `default' macro for autoscan.
11979 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11981 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11984 2002-09-28 Akim Demaille <akim@epita.fr>
11986 * bin/autoscan.in (%c_keywords): Remove.
11987 (&used): Keep only track of the words we might be interested in.
11988 (&output_kind): It is no longer needed to look for non active
11991 2002-09-27 Akim Demaille <akim@epita.fr>
11993 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

11995 * lib/autoscan/functions: Adjust.
11996 * doc/autoconf.texi (Particular Functions): Adjust.
11998 2002-09-27 Akim Demaille <akim@epita.fr>

12002 Thanks to Bill Moseley and Paul Eggert.
12003 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12004 the tmpdir must be created.
12005 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12006 dir be in the build tree, instead of $TMPDIR.
12008 2002-09-27 Akim Demaille <akim@epita.fr>
12010 * bin/autoscan.in: Improve the comments.
12011 (&parse_args): Drop obsolete undocumented options.

12019 Reported by Ralf Corsepius.
12020 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12022 2002-09-26 Akim Demaille <akim@epita.fr>
12024 Single suffix rules and seperated dependencies are not portable.
12026 * doc/autoconf.texi (Installation Directory Variables): Update.
12027 (Limitations of Make): Some about `Single Suffix Rules and
12028 Separated Dependencies'.
12029 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12030 (ifnames, autoscan, autom4te): Un-factor into several rules.
12032 2002-09-25 Paul Eggert <eggert@twinsun.com>
12034 * BUGS (Interoperability bugs): New section. Mention libtool
12035 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12037 2002-09-24 Paul Eggert <eggert@twinsun.com>
12039 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12040 make handles suffix-rules differently from GNU make.
12042 * bin/Makefile.am (SUFFIXES, .in): Remove.
12043 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12044 Move the body of the old .in rule here.
12046 2002-09-16 Akim Demaille <akim@epita.fr>
12048 i960 compilers create `b.out' files by default.
12049 Reported by Ralf Corsepius.
12051 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12052 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12054 2002-09-13 Paul Eggert <eggert@twinsun.com>
12056 * doc/autoconf.texi (Particular Headers): Remove obsolete
12057 reference to `struct timezone' in the description of
12060 2002-09-13 Akim Demaille <akim@epita.fr>
12064 * config/config.sub, config/config.guess: Update.
12065 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12066 * Makefile.am: Adjust.
12068 2002-09-13 Akim Demaille <akim@epita.fr>
12070 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12071 reading config.log when the compiler is rejected.
12072 Suggested by Guido Draheim.
12074 2002-09-13 Akim Demaille <akim@epita.fr>
12076 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12077 (chdir_init) might hang when stat'ing mounted directories.
12078 Reported by Vance Shipley.
12080 2002-09-12 Akim Demaille <akim@epita.fr>
12082 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12085 2002-09-12 Akim Demaille <akim@epita.fr>
12087 * doc/autoconf.texi (Defining Symbols): Present two different
12088 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12089 difference between 1 argument calls, and 2-3 argument calls.
12091 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12093 * doc/autoconf.texi: Review grammar and punctuation.
12095 2002-09-11 Paul Eggert <eggert@twinsun.com>
12097 * doc/autoconf.texi: Fix minor formatting, spelling, and
12099 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12100 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12103 2002-09-11 Akim Demaille <akim@epita.fr>
12105 * doc/autoconf.texi (Questions): Rename as...
12107 (Defining Directories): New.
12109 2002-09-09 Akim Demaille <akim@epita.fr>
12111 * doc/autoconf.texi (Making testsuite Scripts): Update.
12112 Suggested by Nishio Futoshi.
12114 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12116 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12117 plain `@' is wanted.
12119 2002-09-09 Akim Demaille <akim@epita.fr>
12121 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12122 `duplicates', since the algorithm was too naive and could keep
12123 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12124 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12125 Reported by Ralf Corsepius.
12126 * tests/torture.at (Configuring subdirectories): Exercise these
12129 2002-09-09 Akim Demaille <akim@epita.fr>
12131 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12132 looking for a replacement file.
12133 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12134 directory is relative.
12135 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12136 directory definition.
12137 Reported by Andreas Schwab and Jim Meyering.
12139 2002-09-06 Akim Demaille <akim@epita.fr>
12141 * doc/autoconf.texi (Setting Output Variables): Clarify what
12142 precious variables are.
12143 Suggested by Pontus Skoeld.
12145 2002-09-05 Akim Demaille <akim@epita.fr>
12147 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12148 (ifnames, autoscan, autom4te): Since we don't only depend on
12149 configure.ac variables (such as VERSION etc.), but also on prefix
12150 and so forth, depend on Makefile, not configure.ac.
12151 Reported by Alexandre Duret-Lutz.
12152 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12154 2002-09-05 Kevin Ryde <user42@zip.com.au>
12156 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12157 doesn't seem to be confined to ia64, just say "some versions".
12159 2002-09-04 Akim Demaille <akim@epita.fr>
12161 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12163 * Makefile.am (maintainer-clean-local): Remove.
12164 (MAINTAINERCLEANFILES): Remove COPYING.
12166 2002-09-03 Paul Eggert <eggert@twinsun.com>
12168 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12169 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12172 2002-09-03 Akim Demaille <akim@epita.fr>
12174 * configure.ac: Bump to 2.53d.
12175 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12176 as of today, on Automake's team suggestion.
12178 2002-09-03 Akim Demaille <akim@epita.fr>
12182 2002-09-02 Akim Demaille <akim@epita.fr>
12184 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12186 * configure.ac: Disable SITE_MACRO_DIR.
12188 2002-09-02 Jim Meyering <meyering@lucent.com>
12190 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12191 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12192 Also, tweak grammar: s/make sure to/be sure to/.
12194 2002-09-02 Paul Eggert <eggert@twinsun.com>
12196 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12197 directory names are generally preferable to physical names.
12199 2002-09-02 Akim Demaille <akim@epita.fr>
12201 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12202 Reported by Raja R. Harinath.
12203 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12204 * bin/autoupdate.in: Use error instead of die.
12206 2002-09-01 Paul Eggert <eggert@twinsun.com>
12208 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12209 ordinary shell concatenation rather than echo+tr+sed command that
12210 runs afoul of a long-line-related sed bug in Solaris 8.
12212 * bin/autoheader.in (parse_args): --warning -> --warnings.
12214 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12215 stdout, as traditional "ls" does.
12216 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12217 _AC_COMPILER_EXEEXT_O): Likewise.
12218 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12220 * bin/autoconf.as: Add --prepend-include option. This patch was
12221 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12222 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12224 * bin/autoconf.in, configure: Regenerate.
12226 * doc/autoconf.texi (Special Shell Variables): Mention
12227 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12229 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12230 MAILPATH and set PS1, PS2, PS4 to default values, to work
12231 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12232 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12233 the Autoconf documentation specifies; fall back to "unset" only if
12234 this fails. Use a shell for-loop for this rather than an m4 loop,
12235 to shorten the output script.
12237 2002-08-30 Paul Eggert <eggert@twinsun.com>
12239 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12240 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12241 for the CDPATH problem. Document PWD.
12242 (Limitations of Builtins): Document the problem that "cd $foo" and
12243 "ls $foo" may refer to different directories in shells conforming
12244 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12245 example, since the old example is now out of date.
12247 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12248 FOO" and "ls FOO" talk about different directories; this catches
12249 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12252 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12253 of rolling our own unset.
12254 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12255 in practice we needn't worry about CDPATH if unset doesn't work.
12257 * Makefile.in, aclocal.m4, bin/Makefile.in,
12258 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12259 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12260 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12261 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12262 tests/Makefile.in: Regenerate with Automake 1.6.3.
12264 * config/config.guess, config/config.sub, config/mkinstalldirs:
12267 * configure: Regenerate with self.
12269 2002-08-30 Kevin Ryde <user42@zip.com.au>
12271 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12274 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12276 * bin/autom4te.in (Request::load): Correctly test for "do" read
12279 2002-08-29 Akim Demaille <akim@epita.fr>
12281 * lib/Autom4te/General.pm (&xqx): New.
12282 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12283 hand, which is not portable.
12285 * bin/autom4te.in: Use them.
12286 Use &error instead of die.
12287 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12290 2002-08-17 Paul Eggert <eggert@twinsun.com>
12292 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12293 default list of compilers to try, since it was long ago superseded
12294 by the ksh fc builtin. Suggested by Steven G. Johnson.
12296 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12298 * doc/autoconf.texi (Invoking autom4te): End the option table,
12299 fixing a bug introduced by the previous patch.
12300 (Limitations of Make): Add a 'target lookup' subentry in the
12301 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12303 2002-07-29 Mark D. Roth <roth@feep.net>
12305 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12306 options and use $AUTOM4TE_PATH.
12307 * doc/autoconf.texi: Remove documentation of autom4te
12308 --include-envvar and --site-macro-subdir options and document
12309 use of $AUTOM4TE_PATH.
12310 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12311 arguments from each language section.
12313 2002-07-29 Paul Eggert <eggert@twinsun.com>
12315 * doc/install.texi: Include copyright symbol in copyright notice.
12317 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12319 (AM_MAKEINFOFLAGS): New macro.
12320 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12321 * Makefile.am (INSTALL): Use the new macros.
12322 Use -o rather than --output, since "missing" does not grok --output.
12324 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12326 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12327 comments do not always work. Never trust the exit status of
12330 2002-07-24 Kevin Ryde <user42@zip.com.au>
12332 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12333 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12335 2002-07-23 Paul Eggert <eggert@twinsun.com>
12337 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12338 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12339 apparently treats PATH="nonexistent" as if it contained ".".
12340 Bug reported by Stefan `Sec' Zehl.
12342 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12344 * doc/autoconf.texi (Limitations of Make): Mention the special
12345 handling of the obj/ directory by BSD make.
12347 2002-07-20 Kevin Ryde <user42@zip.com.au>
12349 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

12371 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

12378 2002-07-18 Akim Demaille <akim@epita.fr>,
12379 Alexandre Duret-Lutz <duret_g@epita.fr>
12381 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
12382 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
12384 2002-07-17 Russ Allbery <rra@stanford.edu>
12386 * doc/autoconf.texi (Initializing configure): Clarify the
12387 description of the tarname default.
12389 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12391 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12392 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the

12466 2002-06-27 Paul Eggert <eggert@twinsun.com>
12468 * config/install-sh: Quote $src. Prefer || to test's -o option,
12469 as per "Limitations of Builtins".

12610 This improves on an earlier suggestion by H. Peter Anvin.
12612 2002-05-16 Paul Eggert <eggert@twinsun.com>
12614 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12615 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12616 Both macros now accept an optional source-dir arg.
12617 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12619 * NEWS: Document this.
12620 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12622 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12623 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12624 not for GNU extensions; this undoes part of the 2000-11-03 change,
12625 reverting to 2.13-compatible behavior.

12633 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12634 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12635 and it causes a 'test' syntax error if it fails.
12636 Bug reported by Stephen Gildea.
12638 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12639 If prototypes are supported, use them to check this at compile-time,
12640 instead of trying to check it at run-time. If we must do a run-time
12641 check, assume that setvbuf is standard when cross-compiling, as
12642 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12643 Bug reported by Paul D. Smith.
12645 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12646 argument specifying location of getloadavg.c. This removes a
12647 FIXME. This idea was taken from Jim Meyering's implementation in
12649 * doc/autoconf.texi (Particular Functions): Document this.
12650 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12651 that's what the code does; this fixes a bug reported by
12654 2002-05-03 Akim Demaille <akim@epita.fr>
12656 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12657 autopoint instead of gettextize.
12658 ($uses_alocal): Rename as...
12659 ($uses_aclocal): this.
12660 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12661 Suggested by Bruno Haible.
12663 2002-05-03 Akim Demaille <akim@epita.fr>
12665 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12667 2002-04-29 Paul Eggert <eggert@twinsun.com>
12669 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12670 files to be 1 second older; just set them to be the same time.
12671 Also, sleep 1 second after the first aclocal, to work around
12672 problems with sub-second time stamps on the input files.
12674 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12676 * doc/autoconf.texi: Mention "set -e -x" lossage
12677 under node "Limitations of Builtins".

12683 From Christian Cornelssen.
12685 2002-04-29 Akim Demaille <akim@epita.fr>
12687 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12688 of lack of $LINENO support, then the test will compare the $LINENO
12689 in testsuite vs. the lineno in the test file. This is wrong, of
12691 Be sure to protect it.
12692 Reported by Patrick Welche.
12694 2002-04-25 Akim Demaille <akim@epita.fr>
12696 * doc/autoconf.texi (Obsolete Macros): Typo.
12697 Reported by Vladimir Volovich.
12699 2002-04-25 Akim Demaille <akim@epita.fr>
12701 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12702 than some of the input files, hence, on the second run of aclocal,
12703 if some of its input are younger, make them older.
12704 Suggested by Paul Eggert.
12706 2002-04-25 Akim Demaille <akim@epita.fr>
12708 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12714 and ac_subst_vars be sh variables containing the list of
12715 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12717 (_AC_INIT_PREPARE): Use them to log them.
12718 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12719 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12720 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12721 _AC_SUBST_FILES and _AC_SUBST_VARS.
12722 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12724 2002-04-24 Akim Demaille <akim@epita.fr>
12726 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12727 autoheader, so that automake does not complain about a missing
12728 config.h.in that was to be created.
12730 2002-04-23 Akim Demaille <akim@epita.fr>

12879 2002-04-04 Andreas Schwab <schwab@suse.de>
12881 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12882 contains no literal separators.
12884 2002-04-03 Akim Demaille <akim@epita.fr>
12886 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12887 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12888 Use dnl, not the KILL diversion.
12890 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12891 (AC_CONFIG_LINKS): here.
12893 Don't use the KILL diversion, as it kills spurious output, which
12894 results in failures being hidden.
12895 Use m4_defn where appropriate.
12896 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12897 after the second argument.
12899 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12900 syntax, as it is provided by M4sugar.
12901 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12903 2002-04-03 Andreas Schwab <schwab@suse.de>

12906 expanded if $# <= 2.

12917 (_AC_COMPILER_OBJEXT): Use them.
12918 Fixes Debian #138666.
12920 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12922 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12924 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12925 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12926 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12927 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12928 (AC_C_CONST): Same.
12929 (AC_C_INLINE): Same.

12942 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12943 to avoid versions of HP C which don't allow that.
12945 2002-03-27 Paul Eggert <eggert@twinsun.com>
12947 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12948 (AS_SHELL_SANITIZE): Invoke it.
12949 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

12955 2002-03-26 Akim Demaille <akim@epita.fr>
12957 * doc/autoconf.texi (Introduction): The GNATS base moved.
12959 2002-03-25 Paul Eggert <eggert@twinsun.com>
12961 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12962 as POSIX requires, as it doesn't work with Zsh.
12963 * doc/autoconf.texi (Assignments): Document the problem.
12965 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12967 * doc/autoconf.texi (Limitations of Make): Mention more issue
12968 about VPATH, overriding of macros in sub-makes, and handling of
12971 2002-03-21 Paul Eggert <eggert@twinsun.com>
12973 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12974 problem with here-document buffer boundaries.
12976 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12977 when reinvoking the shell, to work around problems with installers
12978 who put strange things like "cd" commands in their environments.
12980 2002-03-19 Akim Demaille <akim@epita.fr>
12982 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

12998 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

13002 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13003 (Limitations of Usual Tools): Add mkdir section.
13005 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13006 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13007 back on AS_DIRNAME to compute prefixes otherwise; this is
13008 roughly what mkinstalldirs does. That way, we need not have
13009 our own filename disassembler. The old disassembler did not
13010 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13012 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13013 Create at_test_all by a series of assignments,
13014 not by a single assignment of a long string. The latter causes ksh
13015 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13016 presumably because of a buffer overrun.
13018 2002-03-14 Paul Eggert <eggert@twinsun.com>
13020 * lib/autotest/general.m4 (at_times_skip):
13021 Renamed from at_times. Now a boolean.
13022 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13023 says 'times: not found'.
13025 2002-03-14 Akim Demaille <akim@epita.fr>
13027 * bin/autoreconf.in (&study_gettextize): New.
13028 (&autoreconf): Handle newest gettextize.
13029 Rerun aclocal if needed.
13030 Suggested by Andreas Schwab.
13032 2002-03-13 Akim Demaille <akim@epita.fr>

13038 * doc/autoconf.texi (Header Portability): New.
13039 Add information about stdint.h and inttypes.h from Paul Eggert.
13041 2002-03-13 Akim Demaille <akim@epita.fr>
13043 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13047 2002-03-12 Akim Demaille <akim@epita.fr>
13049 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13052 2002-03-11 Andreas Schwab <schwab@suse.de>
13054 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13055 does not do it if --with-lispdir is given.

13064 subdirectory should exist.
13066 2002-03-08 Akim Demaille <akim@epita.fr>
13068 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13070 2002-03-08 Akim Demaille <akim@epita.fr>
13072 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13073 aliases the actual variables, and modifications of the former
13076 2002-03-08 Akim Demaille <akim@epita.fr>
13078 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13079 because of C-c: have m4 output in tmp files, then mv them.
13081 2002-03-08 Akim Demaille <akim@epita.fr>
13083 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

13100 2002-03-04 Akim Demaille <akim@epita.fr>
13102 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13103 * lib/autoconf/general.m4 (AC_INIT): More informative error
13104 message for LIBOBJ.
13106 2002-03-04 Akim Demaille <akim@epita.fr>
13108 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13111 2002-03-04 Akim Demaille <akim@epita.fr>
13113 * doc/autoconf.texi (Transforming Names): Equality between target
13114 and host is irrelevant.
13115 (Specifying Names, Canonicalizing): Remove all references to the
13116 backward compatibility hooks. Rather, collect them all into...
13117 (Hosts and Cross-Compilation): this new section.
13118 * doc/install.texi (System Type): Ditto.
13119 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13120 that `--host' implies cross-compilation.
13122 2002-03-04 Akim Demaille <akim@epita.fr>
13124 * doc/autoconf.texi (Evaluation Macros): New.
13125 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13127 (_m4_foreach): Define the variant with immediate evaluation so
13128 that it contains exactly the items, not an expression which
13129 evaluation is the current item.
13130 (m4_re_string, m4_re_word): Don't over quote them.
13132 2002-03-04 Akim Demaille <akim@epita.fr>
13134 Instead of having stacking `shift's evaluated at the end, let
13135 `foreach' loops immediately evaluate them.
13137 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13138 $*. This is the n-th time I change my mind, but hopefully this is
13141 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13143 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13144 it was only a hack for m4_text_wrap.
13145 (m4_car2): Remove, replaced by...
13147 (_m4_foreach): Adjust.
13148 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13149 m4_bpatsubst for clarification.

13200 Fix Autoconf PR/207:
13201 AC_PREFIX_PROGRAM fails with dashed program names
13203 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13204 variable when looking for the prefix program.
13205 Now it also works for shell variables.

13222 sure not to introduce newlines in at_groups.

13236 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13237 cross-compilers, too. This undoes some of the most recent change
13240 2002-02-05 Akim Demaille <akim@epita.fr>
13242 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13265 optional are the sum of the previous files on the command line'.
13266 Also, pass `--reload-state=' on them, so...
13267 (handle_m4): don't.
13268 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13269 (M4sh): Rely on M4sugar.
13270 (Autotest, M4sh, M4sugar): Use frozen files.
13272 2002-01-31 Akim Demaille <akim@epita.fr>

13286 is now run with GCC only.

13296 2002-01-29 Akim Demaille <akim@epita.fr>
13298 * tests/torture.at (Configuring subdirectories): Use configure.in,
13299 so that aclocal 1.4 works.
13300 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13302 2002-01-28 Akim Demaille <akim@epita.fr>
13304 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13307 2002-01-28 Akim Demaille <akim@epita.fr>
13309 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13310 AUTOTEST_PATH *after* it was set.
13311 Don't put `.' in the PATH: the user should be precise and `./' if
13312 needed. In addition, given that the test suite does some `cd', if
13313 `.' is in the path, the `tested programs' sections will report
13314 programs found in the test suite's directory, while during the
13315 tests (performed in their own directory), these programs are no
13316 longer visible. In other words, the results is confusing and
13318 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13369 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

13386 * doc/autoconf.texi (testsuite Scripts): Adjust.
13387 * tests/Makefile.am (package.m4): New.
13388 EXTRA_DIST it since its a source.
13390 2002-01-06 Akim Demaille <akim@epita.fr>
13392 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13393 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13394 and PACKAGE_BUGREPORT from here...
13395 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13397 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13398 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13399 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13400 * tests/tools.at (autoheader): Adjust.
13401 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13403 2002-01-06 Akim Demaille <akim@epita.fr>
13405 * bin/autoscan.in (scan_file): Use `&used'.
13407 2002-01-03 Akim Demaille <akim@epita.fr>
13409 * doc/autoconf.texi (Output): Improved wording regarding use of
13413 2001-12-18 Kevin Ryde <user42@zip.com.au>
13415 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13416 sometimes needing writable input.
13418 2001-12-17 Jim Meyering <meyering@lucent.com>
13420 * doc/autoconf.texi (New Macros): Tweak wording.
13422 2001-12-14 Akim Demaille <akim@epita.fr>
13424 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13425 trailing files, don't apply `-rf' to files which might not be
13426 created by configure (core, core.*, and *.core), but just `rm -f'.
13427 Suggested by Jonathan Kamens.
13429 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13431 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13433 2001-12-14 Akim Demaille <akim@epita.fr>
13435 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13437 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13439 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13440 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13441 abs_srcdir, top_srcpath to abs_top_srcdir.
13442 (_AC_OUTPUT_FILES): Adjust.
13443 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13444 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13445 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13447 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13449 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13450 C/Fortran linking on HP/UX, by extracting the Fortran library
13451 search path from the LPATH line in the $F77 -v output.
13453 2001-12-12 Kevin Ryde <user42@zip.com.au>
13455 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13456 forbidden file descriptors table.
13458 2001-11-26 Akim Demaille <akim@epita.fr>
13460 * bin/autoscan.in (%c_keywords): Build it at top level.
13461 Map to 1 in order to simplify its uses.
13463 2001-11-26 Akim Demaille <akim@epita.fr>
13465 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13466 Remove $filepath, useless.
13467 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13468 variables, they are really part of the tokens.
13469 Split the input line on spaces and then look for tokens.
13470 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13471 because of `lex$U.$(OBJEXT)'.
13472 (&scan_files): Use "@list" instead of join.
13473 * doc/Makefile.am (CLEANFILES): Add *.fns.
13475 2001-11-26 Akim Demaille <akim@epita.fr>
13477 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13478 Remove, replaced by...
13479 * tests/wrappl.in: Be common for all the Perl executables.
13480 In particular autoscan and autoheader want -I.
13481 * configure.ac: Adjust.
13482 * lib/autoscan/headers: errno.h is portable.
13484 2001-11-26 Akim Demaille <akim@epita.fr>
13486 * bin/autoscan.in (used): New.
13489 2001-11-26 Akim Demaille <akim@epita.fr>
13491 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13493 (&scan_sh_file): Remove a duplicate pattern.
13494 (&check_configure_ac): Use long options.
13495 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13497 2001-11-26 Akim Demaille <akim@epita.fr>
13499 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13500 Before, having a line containing the opening of a multi line
13501 comment made the whole line be ignored.
13503 2001-11-26 Akim Demaille <akim@epita.fr>
13505 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13506 (testsuite Scripts): Be one of its subsection.
13507 (Autotest Logs): New.
13509 2001-11-26 Akim Demaille <akim@epita.fr>
13511 Test groups are now run two directories deeper.
13513 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13514 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13516 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13517 top_srcdir, builddir and top_builddir.
13518 Use `at_*dir' relatively to the directory containing the
13519 suite, use `*dir' when relatively to the current group dir.
13521 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13523 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13524 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13525 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13528 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13530 * doc/autoconf.texi (Using System Type): Add an example of `case
13531 $host' usage so people quit using `case $target' everywhere.
13533 2001-11-22 Akim Demaille <akim@epita.fr>
13535 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13536 spotted by Jim Meyering.
13538 2001-11-16 Paul Eggert <eggert@twinsun.com>
13540 This patch implements a `long double' suggestion by Oliver Kiddle.
13542 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13543 static, to catch errors if the value isn't known at compile-time
13544 and the compiler supports dynamic arrays. Change its name from
13545 `_array_' to `test_array' to avoid potential name clashes.
13546 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13547 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13548 better than double. Catch a bug in GCC 2.95.2 x86.
13549 * doc/autoconf.texi (C Compiler): Document the above.
13552 2001-11-13 Akim Demaille <akim@epita.fr>
13554 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13556 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13558 2001-11-13 Akim Demaille <akim@epita.fr>
13560 * lib/autotest/general.m4 (AT_INIT): After having run the test
13561 group, go back to the initial directory, not to at_suite_dir.
13563 2001-11-13 Akim Demaille <akim@epita.fr>
13565 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13566 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13567 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13569 (AT_CHECK_CONFIGURE): Use absolute paths.
13570 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13571 The problem is still the old one: there is no means in M4 (that I
13572 know about) to create a defining macro, because there is no means
13573 to create `$1' etc., therefore, the defining macro ``swallows''
13574 all the arguments meant to the defined macro.
13576 2001-11-13 Akim Demaille <akim@epita.fr>
13578 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13579 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13581 * tests/aclocal.m4: Remove, as it is no longer used.
13583 2001-11-13 Akim Demaille <akim@epita.fr>
13585 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13586 variable names when referring to a single test group, or to
13587 `suite' when referring to the whole test suite.
13588 `at_last_test' is removed: m4 compute at_format itself.
13589 (at_stdout, at_stder1, at_stderr): New variables.
13590 (AT_CHECK): Use them.
13592 2001-11-13 Akim Demaille <akim@epita.fr>
13594 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13596 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13597 Do it as soon as a test fails, don't wait till the end of the test
13599 Don't remove $as_me.[0-9]*, since these files no longer exist.
13601 2001-11-13 Akim Demaille <akim@epita.fr>
13603 * tests/tools.at: Use absolute paths, since we are no longer run
13606 2001-11-13 Akim Demaille <akim@epita.fr>
13608 Now that tests are running in their own private dir, there is no
13609 need to list the files to remove at the end of tests groups.
13611 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13612 (AT_data_files, at_data_files): Remove.
13613 (AT_CLEANUP, AT_DATA): Simplify.
13615 Remove the group dir if !debug && !failed.
13616 * tests/atspecific.m4: Adjust.
13618 2001-11-13 Akim Demaille <akim@epita.fr>
13620 Start a new layout for Autotest: `testsuite' creates
13621 `testsuite.dir' in which the at-check-line etc. files are to be
13622 found, and `testsuite.dir/003' where the test group 3 is run.
13624 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13625 at_check_line_file, at_format, at_test_normalized, at_group_dir
13627 Create the directories.
13628 Use absolute paths for at- files.
13629 (AT_CHECK): Adjust.
13631 2001-11-11 Michael Matz <matz@kde.org>
13633 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13635 (m4_car): Properly quote arguments.
13637 2001-11-13 Akim Demaille <akim@epita.fr>
13639 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13640 with stricter rules on LIBOBJS.
13642 2001-11-12 Paul Eggert <eggert@twinsun.com>
13644 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13645 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13648 2001-11-12 Akim Demaille <akim@epita.fr>
13650 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13652 2001-11-12 Akim Demaille <akim@epita.fr>
13654 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13655 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13656 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13657 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13658 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13659 specify to what the macro should be defined (typically to 1).
13661 2001-11-12 Akim Demaille <akim@epita.fr>
13663 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13666 2001-11-12 Akim Demaille <akim@epita.fr>
13668 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13669 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13670 definition used by Automake where LEX is +/- "${missing} lex" and
13671 `missing' itself contains variables.
13673 2001-11-12 Akim Demaille <akim@epita.fr>
13675 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13676 Now that M4sh pushes BODY, the comments were output at the end of
13679 2001-11-08 Akim Demaille <akim@epita.fr>
13681 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13682 that we can trace macros from aclocal.m4.
13683 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13684 obsoleted, and redirect to the former anyway.
13685 Reported by Ralf Corsepius.
13687 2001-11-08 Akim Demaille <akim@epita.fr>
13689 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13690 processed only if present.
13691 * tests/torture.at (Configuring subdirectories): Use autoreconf
13692 instead of successive calls to autoconf.
13693 Add a nonexistent subdirectory to exercise the patch above.
13694 Reported by Ralf Corsepius.
13696 2001-11-08 Kevin Ryde <user42@zip.com.au>
13698 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13699 doesn't accept .S files.
13701 2001-11-07 Akim Demaille <akim@epita.fr>
13703 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13704 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13705 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13706 * bin/autom4te.in (warn_forbidden): New.
13707 (handle_output): Use it.
13708 Read m4_pattern_forbid with messages.
13710 2001-11-05 Akim Demaille <akim@epita.fr>
13712 * bin/autom4te.in (--normalize): Remove.
13713 * lib/autom4te.in: Adjust.
13715 2001-11-05 Akim Demaille <akim@epita.fr>
13717 * tests/Makefile.am (testsuite): Rename this target as...
13718 ($(TESTSUITE)): this.
13721 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13723 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13724 the --prefix option, also remove it's argument.
13726 2001-11-05 Akim Demaille <akim@epita.fr>
13728 * doc/autoconf.texi (testsuite Invocation): Update.
13729 (Writing testsuite.at): Update.
13731 2001-11-03 Akim Demaille <akim@epita.fr>
13733 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13735 2001-11-03 Akim Demaille <akim@epita.fr>
13737 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13738 (&file_name_is_absolute): New, wrappers around routines from
13740 Use and export them.
13741 (&find_configure_ac): Optionally take a directory where to look at.
13742 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13744 Default @ARGV to `.', not find_configure_ac.
13745 (&autoreconf): Argument is a directory.
13746 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13747 * doc/autoconf.texi (autoreconf Invocation): Update.
13749 2001-11-03 Akim Demaille <akim@epita.fr>
13751 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13752 (@export_forward_subs): New.
13753 Add basename, dirname, and fileparse.
13755 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13756 Don't look for aclocal flags if we already know aclocal is not
13758 Move aclocal.m4t only if it exists.
13759 Reported by Ezra Peisach.
13761 2001-11-03 Akim Demaille <akim@epita.fr>
13763 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13764 passed on command line, defaulting to ./configure.ac if present.
13765 (&maybe_autoreconf, File::Find): Remove, unused.
13766 (&autoreconf): If autoconf is not used, don't try to trace.
13768 2001-11-02 Akim Demaille <akim@epita.fr>
13770 * configure.ac: Bump to 2.52g.
13772 2001-11-02 Akim Demaille <akim@epita.fr>
13776 2001-11-02 Akim Demaille <akim@epita.fr>
13778 * config/config.guess, config/config.sub, doc/standards.texi:
13779 * config/lispdir.m4: Update from masters.
13780 * configure.ac: Bump to 2.52f.
13782 2001-11-02 Akim Demaille <akim@epita.fr>
13784 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13785 Don't run aclocal when aclocal.m4 is not from aclocal.
13787 Don't run libtoolize and gettextize if --install is not given.
13789 2001-11-01 Paul Eggert <eggert@twinsun.com>
13791 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13792 be invoked before _AS_LINENO_PREPARE.
13793 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13794 than character ranges.
13796 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13797 invoking AS_BASENAME. Set the locale variables to 'C' if
13798 possible, as POSIX requires this to get the traditional
13800 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13802 2001-10-31 Paul Eggert <eggert@twinsun.com>
13804 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13805 with {}, as that triggers a bug in Bash 2.05.
13807 (_AS_LINENO_PREPARE): Use Sed rather than
13808 Awk. Fix the sed prepass to work even if there are multiple
13809 instances of $LINENO on the same line. Do not substitute for
13810 other variables like $LINENOT. Do not check file dates; such a
13811 check is unreliable on sufficiently fast machines, and removing
13812 the check makes the code simpler and more reliable. Check for
13813 output and chmod failures.
13815 * doc/autoconf.texi (Special Shell Variables): Document
13818 2001-10-31 Akim Demaille <akim@epita.fr>
13820 * tests/Makefile.am (atconfig): Remove this target, Automake
13823 2001-10-31 Akim Demaille <akim@epita.fr>
13825 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13826 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13827 provided, while it is optional.
13828 * configure.ac: Adjust.
13830 2001-10-26 Paul Eggert <eggert@twinsun.com>
13832 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13833 lib/Autom4te/Struct.pm:
13834 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13837 * doc/autoconf.texi (Special Shell Variables): Document some
13838 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13840 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13841 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13842 eval $LINENO is not portable in practice.
13844 2001-10-24 Akim Demaille <akim@epita.fr>
13846 * lib/Autom4te/General.pm (backname): New.
13848 2001-10-24 Akim Demaille <akim@epita.fr>
13850 * m4/: Remove, merged into...
13853 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13855 * doc/autoconf.texi (Shellology): Mention the problems with bash
13856 2.05's use of ANSI quoting in its `set' builtin.
13858 2001-10-22 Paul Eggert <eggert@twinsun.com>
13860 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13861 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13862 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13863 POSIX decided to standardize on the int flavor of strerror_r.
13864 Always do char* test, as there's no reason not to.
13865 Assign to a char* var, to catch strerror_r that returns int*.
13867 * doc/autoconf.texi (Particular Functions):
13868 Document the above changes. Also, document the fact that
13869 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13871 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13873 2001-10-20 Akim Demaille <akim@epita.fr>

14360 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14361 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14362 be used instead of ':'.
14363 * lib/autotest/general.m4: Replace occurrences of ':' in
14364 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14366 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14368 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14369 arguments. Fixed a typo.
14371 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14373 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14374 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14376 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14378 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14385 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14387 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14388 already have $file). Set output files to binary mode (helps avoid
14389 CR issues on DOSish systems).
14391 2001-09-19 Akim Demaille <akim@epita.fr>
14393 * lib/autotest/general.m4: Englishoes.
14394 From Tim Van Holder and Alexey Mahotkin.
14396 2001-09-18 Paul Eggert <eggert@twinsun.com>
14398 * doc/autoconf.texi (Common Shell Constructs): New node,
14399 documenting AS_DIRNAME.
14400 (Limitations of Usual Tools): Refer to it when discussing dirname.
14401 Also, update discussion of POSIX standard to reflect latest draft.
14403 * lib/autoconf/c.m4:
14404 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14406 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14407 Do not pass a first argument with leading '-'
14408 to expr, by parenthesizing initial integers that might be negative.
14410 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14411 now merely checks whether it is an error to pass an argument
14414 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14415 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14416 whether it is a (compile-time) error to pass an argument to
14417 getpgrp. This simpler test supports the revised documentation,
14418 and is all that AC_FUNC_GETPGRP's users really need.
14420 2001-09-18 Akim Demaille <akim@epita.fr>
14422 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14432 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14434 Add test for AS_BASENAME.
14435 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14436 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14437 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14438 * tests/base.at: Fixed the expected responses. The old ones were
14440 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14441 the documentation claims it should (and how it behaved in 2.13).
14443 2001-09-18 Akim Demaille <akim@epita.fr>
14445 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14446 the AC_CONFIG_COMMANDS invocation.
14447 This also solves the name clash problems.
14448 Don't set the package's ID.
14449 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14450 No longer to be shipped.
14451 (version.in): Remove.
14452 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14453 * lib/autoconf/status.m4: Adjust.
14454 Use `m4_PACKAGE_STRING'.
14455 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14456 the only optional argument is the name of the test suite.
14457 Expect `package.m4' to define the package signature.
14458 * lib/autom4te.in (Autotest): Add `package.m4?'.
14459 * tests/Makefile.am (package.m4): New.
14460 * tests/suite.at: ifnames is a victim.
14462 2001-09-18 Akim Demaille <akim@epita.fr>
14464 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14465 AC_LIBSOURCE, AC_CONFIG_FILES.
14466 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14467 program version string doesn't match the package's.
14468 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14471 2001-09-17 Paul Eggert <eggert@twinsun.com>
14473 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14474 Allow expression to return any value that can fit into unsigned long
14475 (not int, as before). Check for output errors.

14479 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14480 Always include <stdio.h> and <stdlib.h>. Evaluate
14481 the expression in an extra function before these includes. Call
14482 fprintf "%d" only after ensuring the argument is of type 'int'.
14483 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14485 2001-09-17 Paul Eggert <eggert@twinsun.com>
14487 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14488 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14489 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14490 when they don't exist.
14492 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14493 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14496 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14497 version with the version used by fileutils 4.1, except use
14498 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14501 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14503 2001-09-13 Akim Demaille <akim@epita.fr>

14543 * lib/autotest/general.m4 (AT_INIT): Create and remove
14544 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14545 test suites can cohabit.
14547 2001-09-13 Akim Demaille <akim@epita.fr>
14549 * tests/mktests.sh: Don't output banners for empty test files.

14658 the maintainer is dumb enough to do that...
14660 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14661 excellence in M4 quotation: consider `__file__' is active.
14663 And BTW, when invoking m4, pass the --include in the right order:

14815 There is no such envvar since the inception of autom4te.cfg.
14816 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14817 * bin/autoupdate.in: Adjust, and perform more control.
14818 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
14819 * tests/autoconf: Dittowise.
14821 2001-08-31 Akim Demaille <akim@epita.fr>
14823 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14824 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14826 Use -e, not -f, since /dev/null for instance is OK.
14827 (&parse_args): Adjust.
14828 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

14837 * lib/Autom4te/General.pm (&find_peer): Remove.
14838 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

14840 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14841 find the executables for it.

14843 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14845 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14846 indeed related to running the test suite, while passing
14847 --autoconf-dir and others is related to running non installed
14848 Autoconf executables. So don't do that, leave it to...
14849 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14850 * tests/autoscan: New.
14851 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14868 Suggested by Paul Eggert.
14870 2001-08-29 Akim Demaille <akim@epita.fr>

15254 * doc/install.texi, doc/autoconf.texi: Use `autoconf', not

15259 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
15260 `$0.log' as for projects where testsuite is in src, we'd have

15277 * doc/autoconf.texi: Work around Texinfo buglets.
15278 (Transformation Rules): One example is enough, users are expected
15279 to have their brains on. And BTW, use DESTDIR.
15280 (dvar): New macro. Use it.
15282 2001-08-17 Akim Demaille <akim@epita.fr>
15284 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15327 2001-08-15 Akim Demaille <akim@epita.fr>
15329 * Makefile.maint (CVS): New.
15330 (local-check): Run changelog-check. last.
15331 (alpha): Don't depend upon local-check, since...
15332 (cvs-dist): depends upon it.
15334 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15336 * tests/Makefile.am: Use a clean-local rule to remove
15337 autom4te.cache (it's a directory, not a file.
15338 * Makefile.am: Ditto (but maintainer-clean-local).
15340 2001-08-15 Akim Demaille <akim@epita.fr>
15342 * bin/autom4te.in (@m4_warning): New.
15343 (&handle_m4): Use it.
15344 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15345 warnings are issued at each run.
15346 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15347 is in the src tree.
15349 2001-08-15 Akim Demaille <akim@epita.fr>
15351 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15352 don't waste time running `autoupdate --version' works.
15353 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15355 2001-08-13 Akim Demaille <akim@epita.fr>

15371 duration of the test suite.
15373 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15375 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
15376 endianness for comparison instead of relying on AT_CHECK_ENV.
15378 2001-08-11 Paul Eggert <eggert@twinsun.com>
15380 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

15414 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15416 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15417 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15418 * doc/autoconf.texi (C Compiler Characteristics): Update
15419 documentation for AC_C_BIGENDIAN.
15421 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15423 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15424 magic values from an object file when cross-compiling.
15425 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15427 2001-08-10 Akim Demaille <akim@epita.fr>
15429 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15431 Suggested by Russ Allbery.
15433 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15435 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15436 current $prefix to the sub-configures.
15438 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15440 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15441 extension (needed on BeOS). Reported by Guido van Rossum.
15443 2001-08-09 Akim Demaille <akim@epita.fr>
15445 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15447 2001-08-07 Akim Demaille <akim@epita.fr>
15449 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15451 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15452 No need to remove the files before and after the each test, before
15453 each test and at the end of the suite is enough.
15454 Display only the children `times', not the shell's.
15455 If the test failed or was skipped, at-times is not available.
15457 2001-08-07 Akim Demaille <akim@epita.fr>
15459 Always produce testsuite.log, including when there are no
15460 failures. This helps getting information on skipped tests, and
15461 duration of the tests. Err, implement the latter btw.
15463 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15464 Dump information on the first run of each test.
15465 (AT_CLEANUP): Create `at-times' containing the duration of the
15468 2001-08-07 Akim Demaille <akim@epita.fr>
15470 The use of `dumpstat' revealed that `len' was used although it
15471 should not. m4_text_wrap was using it, but in the Autoconf world
15472 where it is legal. Hence (i) test M4sh in its own world, not
15473 Autoconf's, and (ii), ahem, fix the bug :)
15475 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15476 does not like `' instead of [].
15477 (AT_INIT): Forbid `^_?AT_'.
15478 And don't output such tokens.
15479 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15480 `script.as', and `autom4te.cache'.
15481 Remove `empty' and `macro' which are no longer used.
15482 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15483 * tests/m4sugar.at: Use it.
15484 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15486 2001-08-07 Akim Demaille <akim@epita.fr>
15488 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15490 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15492 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15494 2001-08-04 Akim Demaille <akim@epita.fr>
15496 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15497 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15499 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15500 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15501 (AC_F77_MAIN): Likewise.
15503 2001-08-04 Akim Demaille <akim@epita.fr>
15505 Don't rely on M4sugar outputting the patterns in files, since we
15506 might process the output _without_ running m4, hence without these
15509 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15510 * bin/autom4te.in (@Request::includes): Remove, unused.
15511 (@Request::source): Rename as...
15512 (@Request::input): this.
15513 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15514 (&handle_output): Fetch the patterns from the traces.
15515 `$forbidden' and `$allowed' are constant: use m//o.
15516 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15517 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15519 2001-08-04 Akim Demaille <akim@epita.fr>
15521 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15522 autoconf', i.e., in addition to caching traces, cache the output.
15524 * bin/autom4te.in (Request::cache): Rename as...
15525 (Request::id): this.
15526 ($cache, $icache, $tcache, $ocache): New.
15527 (&handle_m4): Save M4 output in the cache instead of $tmp.
15528 (&handle_output): Adjust.
15529 (&up_to_date_p): Check that the output cache is up to date too.
15530 (top level): Run `&handle_m4' iff force or the cache is invalid.
15531 Run `&handle_output' if the output cache is more recent.
15533 2001-08-04 Akim Demaille <akim@epita.fr>
15535 * bin/autom4te.in ($force): New.
15536 (&parse_args, &print_usage): -f, --force is a new option.
15537 (&handle_output): CPP directives might have spaces after `#'.
15538 (&parse_args): The first file only can be frozen.
15540 2001-08-04 Akim Demaille <akim@epita.fr>
15542 Don't let autom4te compute the `include' traces several times:
15543 first check that the trace cache file is up to date, and then
15544 compare its timestamp with that of the output.
15546 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15547 the preamble. Don't require 5.005 as Autom4te::General does it,
15548 and better yet (use `use', not `require'!).
15549 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15550 Class::Struct as Autom4te::Struct.
15551 * lib/Autom4te/General.pm (File::stat): Use it.
15552 (&mtime): New, export it.
15553 * bin/autom4te.in: Use it.
15554 Declare `$req' is invalid if it is outdated.
15555 Don't declare it valid before saving it if something went wrong.
15557 2001-08-04 Akim Demaille <akim@epita.fr>
15559 Autom4te shall not encode Autoconf data, and preselecting traces
15560 must be proposed to the users.
15562 * bin/autom4te.in (@required_trace): Remove.
15564 (&parse_args, &print_usage): -p, --preselect is a new option.
15565 (&up_to_date_p): Adjust.
15566 * bin/autoconf.in: Preselect some Autoconf macros.
15568 2001-08-04 Akim Demaille <akim@epita.fr>
15570 * tests/tools.at (autoconf --trace: user macros): Check traces on
15571 macros invoked without arguments, and macros invoked with multiple
15574 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15576 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15579 2001-08-03 Akim Demaille <akim@epita.fr>
15581 * bin/autoconf.in ($@): Work around the usual sh bug.
15584 2001-08-03 Akim Demaille <akim@epita.fr>
15586 Clean up the handling of the M4 builtins tracing exception.
15588 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15590 (@m4_builtins): Rename as...
15591 (@m4_builtin): this.
15592 (%m4_builtin_alternate_name): New.
15593 (&parse_args): Complete the trace requests with alternate names.
15594 (&handle_traces): Hence no longer do it here.
15595 (&trace_requests): Remove, unused.

15599 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15600 m4_if, and m4_wrap.
15602 2001-08-03 Akim Demaille <akim@epita.fr>
15604 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15605 (m4_divert_pop): Dump the whole diversion stack when a diversion
15607 * bin/autom4te.in (&handle_output): Remember of the first
15608 occurrence of a possibly undefined macro, not the last.
15609 Complain about the possibly undefined macros in the same order as
15610 the appear in the output.
15611 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15612 * tests/tools.at (autoconf: forbidden tokens, basic)
15613 (autoconf: forbidden tokens, exceptions): No longer sort
15614 autoconf's stderr, as it is now deterministic.
15615 Check that `dnl' is caught.
15617 2001-08-01 Akim Demaille <akim@epita.fr>
15619 * configure.ac: Bump to 2.52c.
15621 2001-08-01 Akim Demaille <akim@epita.fr>
15625 * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/.

15631 2001-08-01 Akim Demaille <akim@epita.fr>
15633 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
15636 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
15637 `END', as `Autom4te::General::END' will be triggered.
15638 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15639 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
15640 system to run `mv', `rm', and `cmp'.
15642 2001-08-01 Akim Demaille <akim@epita.fr>
15644 * lib/Autom4te/General.pm (&unique): New.
