1571 On MinGW, substitution of CR and 0xFF fails.
1572 * tests/torture.at (Substitute and define special characters):
1573 MinGW awk cannot handle 0xFF, and on MinGW, the test does the
1574 wrong thing for CR.
1576 2008-03-04 Eric Blake <ebb9@byu.net>
1578 Pull in recent maintainer improvements from coreutils.

1658 Cover more potentially problemtic file names. Use the new
1659 functions.
1661 Properly handle funny file names for headers in config.status.
1662 The test suite did not cover this bug because the code was not
1663 quoting properly the arguments of `rm -f' (which "fails" silently)
1664 as well as the arguments of `diff' (whose output was redirected to
1665 /dev/null so we couldn't see its error message).
1666 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
1667 file names passed to `rm' and `diff'.
1668 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1674 Properly expand @configure_input@ in config.status.
1675 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_MAIN_LOOP):

1678 Report by Eric Blake and Patrick Welche.
1680 2008-03-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1734 Fix more autotest regressions.
1735 * lib/autotest/general.m4 (AT_LINE): Fix regression from

1752 * tests/autotest.at (Using atlocal): Enhance test to catch last
1753 bug.
1755 * doc/autoconf.texi (Limitations of Builtins) <.>: Mention bash
1756 bug.
1758 2008-01-28 Eric Blake <ebb9@byu.net>
1760 Fix regression in handling VAR=VALUE arguments to testsuite.
1761 * lib/autotest/general.m4 (AT_INIT) <PARSE_ARGS_END>: Detect
1762 leading = as invalid. Defer use of command-line variable
1763 assignments...
1764 <PREPARE_TESTS>: ...here, after atconfig has been sourced. Fix
1765 regression in sourcing files.
1766 * tests/autotest.at (Using atlocal): New test to catch this.
1767 (Debugging a successful test, Choosing where testsuite is run):
1768 Use correct shell.
1769 Reported by Ralf Wildenhues.

1772 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Document
1773 BSD behavior on binary input.
1775 Minor testsuite improvements.
1776 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
1777 forks when sanitizing PATH. Always output machine information,
1778 not just when atconfig was located.
1780 Add 'testsuite -C dir'.
1781 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1782 detection...
1783 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1784 argument.
1785 <DEFAULTS>: Delay computation of variables based on $at_dir...
1786 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1787 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1788 <PARSE_ARGS>: Parse new option.
1789 <HELP_TUNING>: Document it.
1790 * tests/autotest.at (Choosing where testsuite is run): New test
1791 for this feature.
1792 (Keywords and ranges): Add test for missing -k argument.
1793 * NEWS: Document this.
1794 * doc/autoconf.texi (testsuite Invocation): Likewise.
1796 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1798 * build-aux/config.guess, build-aux/config.sub,
1799 build-aux/texinfo.tex: Sync from gnulib.
1800 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1801 Likewise.
1803 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1805 * doc/autoconf.texi (Particular Programs): Do not mention the
1806 Autoconf version in which the AC_PROG_INSTALL change was done.
1807 Suggested by Paul Eggert.
1809 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1811 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1812 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1813 mode, we change to the source directory, also set $ac_pwd so we
1814 do not go back to the build tree for the next config subdir.
1815 * tests/torture.at (Deep Package): Extend test to contain two
1816 config subdirs on the top level.
1818 Fix parallel `maintainer-check'.
1819 * Makefile.am (maintainer-check-tests): Depend on `all'.
1820 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1821 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1822 Likewise.
1823 (maintainer-check): Serialize the testsuite runs.
1825 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'

1830 `install -c file1 file2 dir' works.
1831 * doc/autoconf.texi (Particular Programs): Document this.
1832 * NEWS: Update.

1841 Reported by Reuben Thomas.
1843 2008-01-15 Eric Blake <ebb9@byu.net>

1847 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1849 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1850 check_SCRIPTS. Building the wrappers for `all' allows help2man
1851 to use them for the manpages.
1852 Report by Benoit Sigoure.
1854 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1856 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1858 Fix some write failure cases in Autotest.
1859 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully

1868 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1869 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1870 (m4_require): Use m4_do, not m4_join.
1872 Fix some whitespace tests on cygwin.
1873 * tests/tools.at (autom4te and whitespace in file names): Restore
1874 font-lock. Create $TMPDIR before it might be used.
1876 Fix spurious testsuite failure with M4 1.4.11.
1877 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1879 Optimize AC_REQUIRE.
1880 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1881 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1882 (m4_require): Avoid extra macro calls.
1884 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1886 * tests/torture.at (srcdir): Fix quoting.
1888 Do not pass top_srcdir to configure scripts in testsuite.
1889 * tests/autotest.at (srcdir propagation): Copy install-sh to
1890 source tree.
1891 (my only test): Drop setting of `top_srcdir'.
1892 * tests/base.at (Input/Output): Likewise.
1893 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1894 config.guess, and config.sub to test source tree.
1895 Drop AC_CONFIG_AUX_DIR setting.
1896 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1897 * tests/torture.at (Substitute a 2000-byte string): Drop
1898 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1899 (Substitute a newline, datarootdir workaround): Likewise.
1900 (Define a newline): Adjust for linenumber changes in configure.ac.
1901 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1903 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1904 if `pwd` contains whitespace.
1906 Quote $abs_top_srcdir in tests.
1907 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1908 * tests/tools.at (Syntax of the shell scripts): Likewise.
1910 * tests/m4sh.at (LINENO): Quote $0.
1912 Fix testsuite program wrapper for whitespace in `pwd`.
1913 The problem here is that the usual mantra is that command
1914 variables can contain arguments, thus we cannot just escape
1915 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1916 $top_builddir/tests directory early in $PATH, so that the
1917 wrappers are found by their plain name.
1918 * tests/wrapper.as: Put $testdir early in $PATH.
1919 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1921 Proper config.status --file/--header and $srcdir escaping.
1922 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1923 characters in $ac_file_inputs.
1924 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1925 accordingly.
1926 * tests/torture.at (datarootdir workaround): Adjust.
1927 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1929 Fix Autotest for whitespace in `pwd`.
1930 * lib/autotest/general.m4 (AT_INIT)
1931 <at_func_create_debugging_script, Driver Loop>:
1932 Quote $at_group_dir.
1933 * tests/autotest.at (whitespace in absolute testdir): New test.
1935 * lib/autom4te.in: Quote @datadir@.
1937 Proper file name escaping in Autoconf programs and Perl modules.
1938 This includes escaping of characters special to the shell
1939 as well as special to Perl, e.g., leading `<' or `>'.
1940 For example, when $file starts with `>', `open ">$file"'
1941 wrongly tries to append to a different file.
1942 * bin/autoconf.as: Fix quoting for autom4te options.
1943 * lib/Autom4te/General.pm (shell_quote): New function, taken
1944 from coreutils, written by Jim Meyering.
1945 (mktmpdir): Use it.
1946 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1947 and open_quote.

1952 * bin/ifnames.in: Likewise, XFile usage fixes.
1953 * tests/tools.at (autom4te and whitespace in file names): Extend
1954 test. Test twice, with special characters allowed on w32, and the
1955 rest. Test leading and trailing whitespace, for `open_quote'.
1956 (autotools and whitespace in file names): New, analogous test.
1957 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1958 by Russ Allbery and Eric Blake.
1960 Sync from Automake.

1978 Manually resync with gnulib, since 'make cvs-update' no longer works.
1979 * build-aux/config.guess: New upstream version.
1980 * build-aux/config.sub: Likewise.
1982 When using older automake, don't downgrade build-aux/texinfo.tex.

1988 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1989 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1990 #undef as this runs afoul of our new way of creating config.h.
1991 Problem reported by Jim Meyering in
1992 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1994 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1998 for the shell.
1999 * tests/tools.at (autom4te and white space in file names):
2000 New test.
2002 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2003 Document that Tru64 awk always splits $0.
2005 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2007 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2008 `#AT_STOP_...' line at the end of each test.
2010 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2012 * lib/autotest/general.m4 (AT_INIT): For awk line number
2013 extraction script, ensure `$at_group' has a defined value
2014 even for the empty set, and properly quote its usage inside
2015 the awk script.
2017 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2019 * doc/autoconf.texi (Shell Functions): New chapter. Document
2020 IRIX sh $0 issue in functions, move content from ...
2021 (Portable Shell): ... here.
2022 (Shell Script Compiler): Note that shell functions are not
2023 totally unportable any more.
2025 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2026 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2028 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2029 extracting the line numbers of the last needed test.
2031 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2033 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2034 Fix quoting.
2036 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2038 Fix IRIX testsuite debugging failures: $0 in functions.
2039 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2040 Do not use $0 inside a function, as IRIX sh will set that to the
2041 function name rather than the script invocation name.
2043 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2044 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2046 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2047 to extract test scripts.
2048 (AT_INIT): Extract and cache test script line numbers.
2050 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2052 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2053 subsequent fixups; the awk -> here-document conversion trashes
2054 performance too much with AIX sh.
2056 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2058 * tests/local.at: Do not test m4, perl with AT_TESTED.
2060 Diagnose and guard against write errors dealing with config.status.
2061 The general idea is this: all write failures from `configure'
2062 writing `config.status' are indicated by $ac_write_error, which
2063 is only checked at the end. This is safe because config.status
2064 code is not executed before the file is complete. Other write
2065 failures, be they inside config.status, or in sub shell/awk
2066 scripts spawned from configure or config.status, typically need
2067 earlier checking, as their results are used right afterwards.
2068 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2069 before writing config.status, check afterwards.
2070 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2071 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2072 Set `ac_write_error' for write failures to config.status. Barf
2073 upon write failures to temporary files.
2074 Adjust note about closing and reopening the here-document.
2075 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2076 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2077 reopening the here-document.
2078 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2079 Ensure `ac_write_error' does not escape into config.status.
2080 Also, add a couple of code paths not yet exercised in the test
2081 suite: a config file with input from stdin, and a config header
2082 output to stdout.
2083 Suggestion for catching write errors by Bruno Haible.
2085 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2087 Avoid error with Tru64 awk and testsuite lines with many words.
2088 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2089 reads the testsuite, set the field separator to an unusual value,
2090 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2091 even splits the input if $i, i>0, was never accessed in the script.
2093 Revert 2007-10-17 change.
2094 * TODO: Multiline args in config files and headers mean something
2095 different and are not fixed, see
2096 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2097 Report by Stepan Kasal.
2099 * doc/autoconf.texi (Generic Programs): Fix typo.
2101 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2103 AC_*_TOOL does not canonicalize the prefix
2104 * doc/autoconf.texi (Generic Programs): Do not say that
2105 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2107 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2109 Diagnose write errors in config.status instantiations.
2110 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2111 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2112 on write errors.
2113 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2114 Extend test to also check for some write error failures, using...
2115 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2116 Report by Bruno Haible.
2118 Indentation fixups.
2119 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2120 indentation.
2121 (_AT_CHECK): Use less indentation, to save space.
2123 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2125 Add witness macro for @top_build_prefix@ substitution.
2126 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2127 (_AC_OUTPUT_FILE): Mention it here.
2129 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2130 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2132 * lib/autotest/general.m4 (at_func_test): Remove.
2133 (AT_INIT): Pre-extract test groups into separate files.
2134 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2135 Remove at-test-source files together with the $at_group_dir.
2136 * tests/autotest.at (Long test source lines): New test.
2138 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2140 Shell functions and variables may share a namespace.
2141 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2142 limitation.
2144 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2146 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2147 gnulib.
2149 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2151 * lib/autoconf/status.m4: Fix a couple of comment typos.
2153 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2155 2007-11-13 Jim Meyering <meyering@redhat.com>
2157 Clean up the rule to create "expr".
2158 * tests/Makefile.am (expr): Don't redirect directly to target.
2159 Redirect just once, not for each echo statement.
2160 Use $@, not literal "expr".
2162 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2164 Don't worry about preprocessor when testing long long.
2165 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2166 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2167 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2168 These no longer check for preprocessor flaws.
2169 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2170 Do not check for preprocessor flaws.
2172 2007-11-13 Jim Meyering <meyering@redhat.com>
2174 Adapt dependencies, now that a version change doesn't modify configure.ac
2175 * GNUmakefile: Remove "make clean" kludge.
2176 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2177 configure.ac.
2178 Don't redirect directly to target.
2179 Use $@, not literal "version.m4".
2181 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2183 * doc/autoconf.texi (Making testsuite Scripts): Document
2184 ":;{" shorthand as in previous patch.
2186 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2188 * doc/autoconf.texi (Limitations of Builtins): Document problem
2189 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2190 for the workaround.
2191 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2192 Use ":;{" shorthand.
2193 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2195 2007-11-12 Jim Meyering <meyering@redhat.com>
2197 Add more non-srcdir build support.
2198 * GNUmakefile (dummy): Split a long line.
2199 Add -v option to autoreconf invocation.
2201 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2202 * GNUmakefile (dummy): Remove INSTALL.
2204 Remove racy commands to build scripts in bin/ and tests/.
2205 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2206 are guaranteed to be built, remove the rules that tried to build
2207 them. Before, with a parallel build, these rules could lead to
2208 two processes writing tests/wrapper.in concurrently.
2210 Build in man/ only *after* building in bin/ and tests/.
2211 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2212 in both bin/ and tests/.
2214 Accommodate non-srcdir build-from-checkout.
2215 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2216 Use git's --git-dir=$srcdir/.git option.
2217 Add quotes, in case tarball_version_file contains shell meta-characters.
2218 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2219 * configure.ac: Pass "." to git-version-gen.
2221 Avoid spurious test failures due to version skew.
2222 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2224 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2226 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2227 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2228 Remove conftest.dSYM directory.
2229 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2230 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2231 Remove `conftest.*' recursively.
2232 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2233 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2234 Likewise.
2235 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2236 * THANKS: Update.
2237 Report and analysis by Jeff Squyres and Peter O'Gorman.
2239 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2241 Fix typos in variable names.
2242 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2244 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2246 Document that $((expression)) is not portable.
2247 * doc/autoconf.texi (Shell Substitutions): Here.
2249 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2251 Ignore configure --help* errors due to LINENO-impaired shells.
2252 * tests/torture.at (Configuring subdirectories, Deep Package):
2253 In the --help* tests in read-only trees, make `.' temporarily
2254 writable again for the `stderr' file, and ignore errors due to
2255 the attempt to write configure.lineno.
2256 Report by Patrick Welche.
2258 2007-11-10 Jim Meyering <meyering@redhat.com>
2260 Generate package.m4 in build-dir, not srcdir.
2261 * tests/Makefile.am (package.m4): Adjust target.
2262 Don't redirect directly to $@.
2263 (CLEANFILES): Add package.m4.
2264 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2265 in $(srcdir).
2266 When running $(AUTOTEST), search "." before searching $(srcdir).
2268 Avoid a race condition that would make parallel "distclean" fail.
2269 * tests/Makefile.am (distclean-generic): Replace the default,
2270 automake-provided rule with an identical one, but with an additional
2271 dependency on distclean-local. Simply adding the dependency would
2272 cause automake not to emit the rule at all.
2273 * BUGS: Building with -jN works, now.
2275 Distribute git-version-gen.
2276 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2277 since GNUmakefile is distributed, and requires it for dist* rules.
2279 Remove two more generated files from version control.
2280 * INSTALL: Remove generated file.
2281 * lib/autoscan/autoscan.list: Remove generated file.
2283 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2285 * GNUmakefile (PATH): Remove stray apostrophes; they become
2286 part of PATH, which isn't wanted here.
2288 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2290 New config files output variable `top_build_prefix'.
2291 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2292 `top_build_prefix'.
2293 * doc/autoconf.texi (Preset Output Variables): Document it.
2294 * NEWS: Update.
2295 Report by Bob Friesenhahn.
2297 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2298 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2299 function, to parametrize arithmetic with expr vs. the shell.
2300 Use it where possible.
2301 Suggestion by Benoit Sigoure.
2303 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2305 Adjust the documentation of autotest WRT atlocal.
2306 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2307 when using Automake, to write a rule to produce atlocal, since it's
2308 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2309 distributed, not atconfig.in.
2311 2007-11-04 Eric Blake <ebb9@byu.net>
2313 Update list information.
2314 * README: Mention new autoconf-commit list.
2315 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2317 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2319 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2321 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2323 * build-aux/.gitignore: Ignore mkinstalldirs.
2325 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2327 2007-11-03 Jim Meyering <meyering@redhat.com>
2329 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2330 * build-aux/git-version-gen: This syncs from coreutils.
2332 Adjust the build procedure so "make check" works reliably.
2333 * README-hacking: Include an extra step between "make" and
2334 "make check" to ensure that the latter passes.
2336 Use just-built tools, when possible.
2337 * GNUmakefile (PATH): Set and export here, ...
2338 (dummy): ... rather than here.
2340 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2341 and Andreas Schwab <schwab@suse.de>
2343 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2344 exit status bug.
2346 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2348 * configure.ac (AC_PREREQ): Require version 2.60, for
2349 AC_PROG_SED, AC_PROG_GREP.
2351 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2352 and Jim Meyering <meyering@redhat.com>
2353 and Andreas Schwab <schwab@suse.de>
2354 and Eric Blake <ebb9@byu.net>
2356 Document a bug in GNU Bash with compound commands and redirections.
2357 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2358 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2359 workaround.
2361 2007-11-03 Eric Blake <ebb9@byu.net>
2363 Support m4 1.4.5 in testsuite.
2364 * tests/torture.at (Define a newline): Exclude line numbers in
2365 error message.
2366 Reported by Ralf Wildenhues.
2368 2007-11-03 Jim Meyering <meyering@redhat.com>
2370 Remove automake-provided files from version control.
2371 * build-aux/elisp-comp: Remove file.
2372 * build-aux/install-sh: Remove file.
2373 * build-aux/missing: Remove file.
2374 * build-aux/mdate-sh: Remove file.
2375 * build-aux/.gitignore: New file.
2376 Suggestion from Ralf Wildenhues.
2378 2007-11-03 Eric Blake <ebb9@byu.net>
2380 Adjust version comparison to account for git snapshot numbers.
2381 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2382 component separator.
2383 * doc/autoconf.texi (Number processing Macros)
2384 <m4_version_compare>: Document this change.
2385 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2387 2007-10-30 Bruno Haible <bruno@clisp.org>
2389 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2390 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2391 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2392 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2393 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2394 Suggested by Paul Eggert.
2396 2007-10-28 Jim Meyering <meyering@redhat.com>
2398 * README-hacking: Autoconf, Automake, and Perl are required to build.
2399 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2401 2007-10-28 Jim Meyering <meyering@redhat.com>
2403 README-hacking: Recommend running autoreconf -vi.
2404 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2405 so that we use just-built tools when they're available.
2406 Suggestions from Ralf Wildenhues.
2408 2007-10-28 Jim Meyering <meyering@redhat.com>
2410 Make inter-release --version output more useful.
2412 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2413 which indicates that it is built using the 19th change set
2414 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2415 is a prefix of the commit SHA1.
2416 * build-aux/git-version-gen: New file.
2417 * configure.ac: Run it to set the version.
2418 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2419 * Makefile.am (dist-hook): Arrange so that .version appears only
2420 in distribution tarballs, never in a checked-out repository.
2421 * .gitignore: Add .version here, too. Just in case.
2422 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2423 not configure.ac, now that the version number changes automatically.

3683 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

3724 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3725 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3726 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3727 works but the latter doesn't, then it's a valid type.
3728 This lets people use function types and so forth.
3729 For C++ there doesn't seem to be a simple solution, so leave it alone.
3730 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3731 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3732 AC_CHECK_TYPE; that wasn't documented or necessary.

3839 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3841 * doc/autoconf.texi (Parentheses): Mention problem with (( in
3842 shells.
3844 2007-02-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3845 and Paul Eggert <eggert@cs.ucla.edu>
3847 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix quoting
3848 errors introduced in last change.
3850 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3852 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
3853 an actual carriage return. Use "ac_cr" to contain the actual
3854 carriage return.
3855 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3856 with traditional Awk and begin.
3857 * tests/torture.at (Limitations of Builtins): Document the problem
3858 with Bash 2.03 printf.
3859 (Substitute and define special characters):
3860 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
3862 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3864 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3865 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3866 will not wait for input with a script containing only a BEGIN
3867 rule.
3869 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3871 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
3872 requirements.
3873 * README: Likewise.
3875 2007-02-02 Eric Blake <ebb9@byu.net>
3877 * NEWS: Update copyright.
3879 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
3880 broken.
3881 * configure.ac: Update error message.
3882 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

3891 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3893 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3894 latest version.
3895 (Shell Substitutions): Note problems with @{var:=value} etc.
3896 Add a new section for problems with @{#var} etc. Problem noted
3897 by Ralf Wildenhues. See:

3900 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3902 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3903 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3904 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3905 substitution will still be done by the special code.
3906 Report by Jim Meyering.
3908 * doc/autoconf.texi (File System Conventions): Mention that
3909 $PATH_SEPARATOR is for the build system only.

3919 * tests/torture.at (Substitute and define special characters):
3920 Test all 8 bit non-NUL characters.
3921 Report against Automake by Patrick Welche.
3923 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3925 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3927 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3929 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3930 early on the reader side, drop stderr of the input to avoid
3931 `broken pipe' error output; this may happen even with shell
3932 builtin `echo' of some bash versions. Reports by Ian Macdonald
3933 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3935 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3937 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3938 separate items of `ac_user_opts', to avoid long lines.
3939 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3941 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3943 * doc/autoconf.texi: Fix some typos.
3945 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3947 Fix some wording problems noted by Paolo Bonzini in:
3948 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3949 * doc/autoconf.texi (Signed Overflow Examples): Give more
3950 discussion about the allow_superuser_privileges example,
3951 and change it a bit to make things clearer.
3952 (Optimization and Wraparound): Clarify whether the compiler
3953 will generate an infinite loop for the example derived from
3954 Autoconf's mktime test.
3955 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3956 Also, clarify unsigned multiplication overflow.
3958 2007-01-04 Eric Blake <ebb9@byu.net>
3960 * bin/Makefile.am (RELEASE_YEAR): New macro.
3961 (edit): Use it to supply correct copyright year to scripts.
3962 * bin/autoconf.as (version): Use it.
3963 * bin/autoheader.in ($version): Likewise.
3964 * bin/autom4te.in ($version): Likewise.
3965 * bin/autoreconf.in ($version): Likewise.
3966 * bin/autoscan.in ($version): Likewise.
3967 * bin/autoupdate.in ($version): Likewise.
3968 * bin/ifnames.in ($version): Likewise.
3970 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3972 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3973 feedback. The most important changes document what happens when
3974 you convert an out-of-range value to a signed integer type, and
3975 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3976 a + b.
3978 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3979 rewrite, taking notions from the recent discussion on the gcc and
3980 autoconf mailing lists; please see
3981 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3982 and follow the many links.
3983 (Integer Overflow Basics, Signed Overflow Examples):
3984 (Optimization and Wraparound, Signed Overflow Advice):
3985 (Signed Integer Division): New sections.
3987 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3989 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3990 preprocessor macro arguments in traced name.
3991 * doc/autoconf.texi (Defining symbols): Document longstanding
3992 support for AC_DEFINE-ing macros with arguments, and document
3993 behavior when the same variable has multiple AC_DEFINEs.
3994 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3995 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3996 macros directly, giving much shorter and simpler code.
3998 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4000 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4001 space before "$ac_configure_args" to prevent a 'config.status
4002 --recheck' failure if ac_configure_args doesn't contain a leading
4003 space. This works around a problem with the XEmacs configure.ac,
4004 which uses the (undocumented) ac_configure_args variable
4005 inconsistently with Autoconf.
4007 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4009 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4010 Include <limits.h>, and use its INT_MAX to rewrite the
4011 j loop so that it does not overflow 'int'. Problem reported by
4012 Ralf Wildenhues in
4013 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4014 Play it safe by shifting left by 1 rather than multiplying by 2,
4015 as GCC is less likely to optimize this away when the value
4016 is signed (when it assumes overflow leads to undefined behavior).
4017 Also, don't assume time_t uses two's complement.
4019 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4021 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4022 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4023 dumps core on it. Report by Tim Rice.
4025 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4027 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4028 --disable-option-checking to --help output even when
4029 AC_PRESERVE_HELP_ORDER is not used.
4030 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4031 --with argument, rather than argument with [-.] replaced by
4032 underscores.
4033 * NEWS: Fix typo in previous change; the news was in the
4034 wrong section.
4036 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4038 * NEWS: Warnings are now generated by default for unknown
4039 --enable-* and --with-* options.
4040 * doc/autoconf.texi (Option Checking): Renamed from
4041 (Configure Option Checking). Tighten up the wording a bit.
4042 (External Software, Package Options): Cross-reference to Option
4043 Checking, and use this to shorten our section.
4044 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4045 "$x" to test "x$foo" != x.
4046 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4047 Don't warn if $enable_option_checking is "no".
4048 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4049 ac_unrecognized_opts to the empty string.
4050 Don't echo the unrecognized opts, as this might mishandle
4051 backslashes or leading -.
4052 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4053 usage next to the other --disable-FEATURE options in the
4054 help string.
4056 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4058 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4059 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4060 Print warning for unrecognized --with and --enable options
4061 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4062 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4063 Disable option checking when subdirs are configured.
4064 (AC_OUTPUT): If warnings are enabled, print warning about
4065 unrecognized --with and --enable options at the end of
4066 the configure output (as well as at the beginning).
4067 * doc/autoconf.texi (Option Checking): New node.
4068 Document new option warning functionality.
4070 2006-12-16 Eric Blake <ebb9@byu.net>
4072 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4073 * NEWS: Start news for current version.
4075 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4077 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4078 Define HAVE_GETMNTENT to 1, not to the empty string.
4079 Problem originally reported by Jochen Friedrich in
4080 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4082 This change prompted by a problem report by Andrey Simonenko in
4083 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4084 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4085 object-like macros only, in the traditional portable character
4086 set.
4087 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4088 Warn about attempts to define things that are not identifiers.
4089 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4090 awful hack that AC_DEFINEd macro names containing parentheses.
4092 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4094 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4095 too drastic, even if Texinfo in theory requires it for info mode.
4097 (config.status Invocation): Renamed back from Recreating a
4098 Configuration).
4099 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4100 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4102 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4104 * NEWS: Version 2.61a.
4106 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4107 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4109 * NEWS: Document changes with echo and printf, and the lack
4110 of limits on the total size of multi-line values of substituted
4111 variables, and the AC_FUNC_FSEEKO fix.
4113 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4115 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4116 Writing configure.ac.
4117 (Autoconf Input Layout): Renamed from configure.ac Layout.
4118 (Recreating a Configuration): Renamed from config.status Invocation.
4119 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4120 (acconfig Header): Renamed from acconfig.h.
4121 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4122 (Writing Testsuites): Renamed from Writing testsuite.at.
4123 (Autom4te Cache): Renamed from autom4te.cache.
4125 * BUGS: Remove mention of VPATH problem, since it's now documented
4126 not to be a bug in the Autoconf build procedure itself, but rather
4127 a problem with the proprietary `make' programs.
4129 * doc/autoconf.texi (Build Directories): Add a cross reference
4130 to VPATH and Make.
4132 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4133 * doc/standards.texi: Sync from gnulib.
4135 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4136 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4137 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4138 generated automatically.
4140 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4142 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4143 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4144 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4146 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4148 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4149 `CEOF$ac_eof' special marker, the awk script cannot contain a
4150 line matching `^CEOF', so this is not needed any more.
4151 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4152 special marker in the test.
4154 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4156 * tests/tools.at (autom4te preselections): Use `find -newer';
4157 remove one of the sleeps.
4159 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4160 more readable, using ...
4161 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4163 * doc/autoconf.texi (autoheader Invocation): Do not double-
4164 quote the parameter of `AH_BOTTOM' in the example.
4166 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4168 * doc/autoconf.texi (Configuration Headers): Remove the
4169 example with multiple input files.
4170 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4171 multiple input files.
4173 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4175 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4176 creating the awk substitution script, handle one input line at a
4177 time, so that the maximum length of a substituted (multi-line)
4178 value is not limited by the size of the sed pattern space.
4179 The trade-off is a slightly repetitive sed script.
4180 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4181 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4182 * tests/torture.at (Substitute a 2000-byte string): Increase the
4183 test with several long lines, they should not be caught by sed
4184 limits any more.
4186 * tests/tools.at (autom4te preselections): New test, to flag
4187 entries missing from autom4te.cfg.
4188 Report by David Byron <dbyron@hheld.com>.
4190 * tests/torture.at (Substitute a 2000-byte string): Actually use
4191 AC_PROG_AWK, so the last change works as intended.
4192 (Substitute and define special characters): Likewise.
4193 (Substitute a newline): Likewise.
4195 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4196 instead of `awk' consistently.
4197 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4198 * tests/torture.at (Torturing config.status): Test both the
4199 result of AC_PROG_AWK and plain awk.
4200 (Substitute a 2000-byte string): Likewise.
4201 (Substitute and define special characters): Likewise.
4202 (Substitute a newline): Likewise.
4204 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4206 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4207 can be assigned to a function pointer. Problem reported by
4208 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4209 part of a patch by Ralf Wildenhues in that same bug report.
4211 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4213 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4214 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4216 2006-12-01 Eric Blake <ebb9@byu.net>
4218 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4219 cross-compiling from cygwin to mingw.
4220 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4221 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4222 to lib/autoconf/c.m4.
4224 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4226 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4227 string for more reliable failure. Wrap the entire test that
4228 causes the broken Solaris printf to dump core, in a subshell,
4229 so the segmentation fault message is reliably suppressed.
4230 Fix shell expansion errors by using /usr/ucb/echo always;
4231 avoid an error on systems without it by another subshell.
4232 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4233 subshell-$as_echo to `as_echo', for better error message.
4235 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4237 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4238 `BASH_SOURCE' contain a newline, set them to empty, as they may
4239 not be unset.
4241 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4243 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4244 years and is too hard to maintain now. The last straw was
4245 reported by Jerker Baeck in
4246 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4247 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4248 * doc/autoconf.texi (Particular Functions): Move
4249 AC_FUNC_SETVBUF_REVERSED from here...
4250 (Obsolete Macros): ... to here. Say that it does nothing now.
4251 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4252 Turn into (almost) a no-op.
4254 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4255 (AC_C_VOLATILE):
4256 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4257 These macros are obsolescent and new applications shouldn't need them.
4258 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4259 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4260 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4261 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4262 (AC_FUNC_VPRINTF): Likewise.
4263 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4264 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4265 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4267 * doc/autoconf.texi (Setting Output Variables): Mention that
4268 @VAR1@VAR2 has unspecified behavior. Problem reported by
4269 Ralf Wildenhues.
4270 * NEWS: Mention this.
4272 * Makefile.am: Put only a single '#' into the copyright notice,
4273 so that it's also present in the output file. Standardize wording
4274 in makefile copyright notices to match GNU coding standards.
4275 * bin/Makefile.am: Likewise.
4276 * doc/Makefile.am: Likewise.
4277 * lib/Makefile.am: Likewise.
4278 * lib/freeze.mk: Likewise.
4279 * lib/autoconf/Makefile.am: Likewise.
4280 * lib/autoscan/Makefile.am: Likewise.
4281 * lib/autotest/Makefile.am: Likewise.
4282 * lib/m4sugar/Makefile.am: Likewise.
4283 * man/Makefile.am: Likewise.
4284 * tests/Makefile.am: Likewise.
4285 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4286 one-line file.
4288 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4290 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4291 in the sed script that mangles the awk script: delete up to the
4292 first exclamation mark only.
4293 * tests/torture.at (Substitute and define special characters):
4294 Test '!' too.
4296 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4298 Rewrite config files generation: avoid quadratic growth in
4299 the number of substituted variables by using awk instead of sed
4300 for the bulk of the substitutions.
4301 * NEWS: Mention this.
4302 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4303 forbidden in the output (and thus input) file.
4304 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4305 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4306 generate just one large awk script for substitutions,
4307 eliminating much of the earlier complexity, while adding some
4308 new complexity. Only expand the substitution templates at
4309 configure time, for smaller configure script size. If
4310 _AC_SUBST_FILES are used, test 'awk' for working getline support
4311 at config.status time. If absent, interpolate through the
4312 shell. The awk script was written with much help
4313 from Paolo Bonzini and Paul Eggert.
4314 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4315 (_AC_SED_FRAG_NUM): Likewise.
4316 (_AC_SUBST_CMDS): Renamed from...
4317 (_AC_SED_CMDS): ...this.
4318 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4319 * tests/torture.at (Substitute a 2000-byte string): Also
4320 substitute a line with 1000 words, and a variable with several
4321 long lines.
4322 (Substitute and define special characters): Test awk special
4323 characters, and put substitution input strings `@foo@' in the
4324 output, to test that no recursion happens; test several other
4325 combinations from Paolo Bonzini.
4327 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4329 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4330 that replaced echo with AS_ECHO where this wasn't necessary.
4331 Problem reportd by Ralf Wildenhues.
4332 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4333 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4334 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4336 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4338 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4340 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4342 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4343 that traditional Awk lacks 3-arg "split". It has it.
4344 Mention that FS must be a single character, and a few other
4345 99-byte limits of traditional Awk.
4346 Mention that if (i in a) doesn't work with traditional Awk.
4348 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4350 * tests/autotest.at (BSx641-newline in command):
4351 (BS-BS-newline in command, BSx640-newline in command):
4352 (Newline-CODE-BS-newline in command):
4353 (Single-quote-BS-newline in command):
4354 (Single-quote-newline-BS-newline in command):
4355 Use printf '%s\n' instead of echo, for portability to hosts
4356 where echo interprets backslashes. This will break on hosts
4357 that lack printf, but for now let's assume all such hosts
4358 are dead (if not, we should get reports of test failures).
4360 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4362 'echo' has some portability problems, when given a first argument
4363 with a leading '-', or when given any argument containing '\'.
4364 Avoid using 'echo' in these cases.
4365 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4366 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4367 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4368 * lib/autotest/general.m4 (AT_INIT): Likewise.
4369 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4370 argument might be unportable.

4385 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4386 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
4387 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
4388 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4389 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4390 * bin/autoconf.as: Redo verbose flag implementation, as the old
4391 scheme wouldn't work with AS_ECHO.
4392 * lib/autotest/general.m4 (AT_INIT): Likewise.
4393 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4394 Don't use ECHO_T, since ECHO_N is now reliable.
4395 * lib/autotest/general.m4 (AT_INIT): Likewise.
4396 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4397 rather than using a here-document to put the script into a file.
4398 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4399 use AS_ECHO.
4400 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4401 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4402 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4403 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4404 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4405 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4406 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4407 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4408 operand, as AS_ECHO requires. Avoid double file name expansion.
4409 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4410 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4411 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4412 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4413 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4414 Double-quote strings that would otherwise contain M4 comments.
4415 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4417 * configure.ac (AC_INIT): Bump to 2.61a.
4418 * NEWS: Likewise.
4420 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4422 Version 2.61.
4424 * configure.ac (AC_INIT): Bump to 2.61.
4425 * NEWS: Likewise.
4427 * tests/autotest.at (Macro with backslash in a test title):
4428 Comment out for now, as this tests neither fails nor passes
4429 reliably. Problem reported by Ralf Wildenhues.
4431 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4433 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4434 in previous change, which caused test failures.
4436 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4438 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4439 code for --enable, --disable, --with, and --without to...
4440 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4441 * doc/autoconf.texi (Package Options):
4442 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4444 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4446 Import these changes from config via gnulib:
4448 2006-11-15 Ben Elliston <bje@gnu.org>
4450 From Josselin Mouette <joss@debian.org>:

4477 on a char value; thanks to Paul Eggert for the code.
4478 Both of these suggestions from Eugene Y. Vasserman.
4481 Import these changes from texinfo via gnulib:
4483 2006-11-08 Karl Berry <karl@gnu.org>
4485 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
4486 as well as pdf images, since they are supported in pdftex with
4487 no further ado.
4489 2006-11-05 Karl Berry <karl@gnu.org>
4491 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.
4493 2006-11-13 Paul Eggert <eggert@cs.ucla.edu>
4495 * NEWS: Document the AC_ARG_WITH change.
4497 2006-11-13 Bruno Haible <bruno@clisp.org>

4505 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4507 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4508 benefit of platforms like Solaris+GCC where it is common to have a
4509 non-working g++ installation.
4511 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4512 and Joel E. Denny <jdenny@ces.clemson.edu>
4513 and Paul Eggert <eggert@cs.ucla.edu>
4515 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs

4519 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4521 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4522 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4523 Imported from a similar patch to gnulib by Bruno Haible.
4525 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4527 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
4528 * doc/autoconf.texi (C Compiler): Document them.
4529 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
4530 New macros, taken from gnulib.
4532 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
4534 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
4535 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
4536 Matthew Woehlke.
4538 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4540 * tests/torture.at (Configuring subdirectories): Do not skip
4541 Automake 1.10 nor future Automake 11.1 (sic).
4543 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4544 and Stepan Kasal <kasal@ucw.cz>
4546 Handle special characters in test case titles correctly.
4547 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4548 properly.
4549 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4550 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4551 argument. Extend to check titles printed by ./micro-suite and
4552 ./micro-suite -l and the title in micro-suite.log.
4553 (Backquote in a test title,
4554 Single-quote in a test title,
4555 Double-quote in a test title): Don't expect failure anymore.
4556 (Backslash in a test title): Put a non-whitespace character after the
4557 backslash so that Bourne shells might actually see it as an escape
4558 sequence.
4559 (Brackets in a test title,
4560 Pound in a test title,
4561 Comma in a test title,
4562 Quoted Macro in a test title,
4563 Macro in a test title,
4564 Macro with single-quote in a test title): New tests.

4567 Macro with backslash in a test title): New tests expected to fail.
4568 * tests/torture.at (#define header templates): M4-quote this title in
4569 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4570 The visible effect was a stray [] in the testsuite output.
4572 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4574 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4575 `trap ... 0' inside a function, for AIX sh.
4577 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4579 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4580 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4581 5363) simply issues a warning when dividing by zero at compile
4582 time. Problem reported by Elias Pipping.
4584 2006-10-26 Eric Blake <ebb9@byu.net>
4586 * THANKS: Update.
4587 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4588 show effect on macros that expand with commas.
4589 Reported by Joel E. Denny.
4591 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
4592 Also work with M4 1.4.8.
4594 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
4596 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
4597 Jim Meyering.
4599 2006-10-25 Stepan Kasal <kasal@ucw.cz>

4602 `--force' always rewrites the output file.
4604 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4606 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
4607 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.

4615 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4616 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4617 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4618 reported by Nelson H. F. Beebe for Coreutils 6.4.
4620 * tests/tools.at (autoconf --trace: user macros): Remove test
4621 for tracing multiline macros, since m4 1.4.7a uses a different
4622 way to number lines. Problem reported by Ralf Wildenhues.
4624 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4626 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4627 /dev/null since the heuristics for interactive behaviour was
4628 fixed in CVS m4.
4630 * bin/autom4te.in: With --force, always refresh the output
4631 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4633 * bin/autoconf.as: Fix the verbose message at the end.
4635 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4652 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4653 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4655 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4657 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
4659 2006-10-19 Eric Blake <ebb9@byu.net>
4661 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.

4681 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4683 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4684 looking for special shell characters.
4685 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4686 macro defined by AS_VAR_PUSHDEF before passing it as a
4687 parameter.
4688 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):

4693 Likewise.
4694 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
4695 AS_VAR_* properly.
4696 * tests/m4sh.at (AS_LITERAL_IF): New test.
4698 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4700 (Imported from Automake.)
4701 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4702 which incorrectly sets the mode of an existing destination
4703 directory. In some cases the unpatched install-sh could do the
4704 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4705 system. We hope this is rare in practice, but it's clearly worth
4706 fixing. Problem reported by Alex Unleashed in
4707 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4708 Also, don't bother to check for -m bugs unless we're using -m;
4709 suggested by Stepan Kasal.
4711 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

4718 Report from Bruno Haible.
4720 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4721 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4722 gnu and gnits modes.
4724 Import this change from Config:
4726 2006-09-20 Ben Elliston <bje@gnu.org>
4727 * build-aux/config.sub (score, score-*): New.
4729 Import this change from Gnulib:
4731 2006-09-16 Karl Berry <karl@gnu.org>
4732 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4733 to avoid sectioning errors.
4735 Import these changes from Texinfo:
4737 2006-10-04 Karl Berry <karl@gnu.org>
4738 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4739 (\quoteexpand): rename to \rquoteexpand.
4740 (\codequoteleft): new def, to look for @set codequotebacktick.
4741 (\lquoteexpand, \quoteexpand): new defs.
4742 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.

4758 added to the template can get mangled.
4760 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4762 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4763 include the default headers, and redefine obstack_chunk_alloc
4764 and obstack_chunk_free. Fixes false failure with glibc.
4766 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4768 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4769 for backward compatibility with Libtool 1.5.22. Problem reported
4770 by Ralf Wildenhues.

4774 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4775 AC_PROG_CC.

4778 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4780 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4781 the NonStop platform.
4782 * doc/autoconf.texi (Posix Variants): Likewise.
4783 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4785 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4786 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4787 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4788 Use a better substitute, by inspecting the output of "ls"
4789 rather than just using ":".
4790 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4791 rather than AS_EXECUTABLE_P, since we needn't worry about
4792 non-regular files here.
4794 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4795 due to configuration hassles with this. See Tonya Underwood's report
4796 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4797 * doc/autoconf.texi (Special Shell Variables): Likewise.
4799 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4800 Stepan Kasal <kasal@ucw.cz>
4802 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4803 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4805 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4807 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4808 initialization which is not inherited through the environment
4809 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4810 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4812 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4814 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4815 problems with mkdir -p -m.

4819 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4820 comment about ac_cpp_err; it was incorrect, and anyway
4821 ac_cpp_err is being removed below.
4822 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4823 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4824 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4825 nobody uses it.
4826 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4827 with werror_flag and conftest.err and so forth. This is more
4828 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4829 and anyway the user shouldn't normally want to see this gorp logged.
4830 Problem reported by Ralf Wildenhues.
4831 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4832 empty, not 'no', since the rest of the code uses 'test -z'.
4834 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4836 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4837 Use a single call to AC_DO_TOKENS rather than multiple, for
4838 efficiency.
4839 (_AC_LINK_IFELSE): Test that resulting file is executable.
4840 Problem reported by mwoehlke in
4841 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4843 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4844 than creating a file to use with test -x; this is much faster.
4846 2006-10-02 Bruno Haible <bruno@clisp.org>
4848 * lib/autom4te.in (Automake-preselections): Add
4849 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4851 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4853 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4854 standard error, `experr' should be used, not `expout'.
4856 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4858 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4859 fseeko testing program twice; just use the earlier result.
4860 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4861 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4862 still doesn't let the program compile.
4863 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4864 failed.
4866 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4867 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4868 include it, without including anything else.
4869 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4870 expressions.
4871 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4873 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4875 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4876 `error.h', and include it, for a `error_at_line' prototype.
4877 Use a nonempty format string in the link test.
4878 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4879 for a declaration of wait3.
4881 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4883 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4884 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4885 can apply to constants too, and that it checks for macro defns.
4886 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4887 and simply cast the identifier to void. This handles structure
4888 values. Problem reported by Ralf Wildenhues.
4889 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4891 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4944 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
4945 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
4946 --error-output, to avoid warnings with M4 2.0.
4948 2006-09-19 Stepan Kasal <kasal@ucw.cz>
4950 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

4959 2006-09-14 Stepan Kasal <kasal@ucw.cz>
4961 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
4962 mistaken comment: the path has to be relative; do not use
4963 the path at runtime.
4965 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4967 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

4975 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4977 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
4978 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
4979 for the existence of the directory at configure-time. That's
4980 too late, anyway. Problem reported by Stefan Seefeld.
4982 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4983 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4984 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4986 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4988 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4989 works with GNU M4 1.4.3 again; make the normalized form
4990 match the current m4 message; fix the description.
4991 * test/tools.at (autom4te cache): Adapt to the change.
4993 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4995 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4996 to catch glibc bug 2821
4997 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4999 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
5000 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
5001 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
5002 assume C89.

5020 by Dries Kimpe.
5022 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5024 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
5025 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
5026 accept files with extension `.f'. For consistency, also prefer
5027 xlf over f77.
5028 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
5029 from last patch.

5050 except the first two arguments are reversed.
5051 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
5052 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
5053 caches nor outputs a diagnostic. Suggested by Bruno Haible.

5064 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
5065 programs should use their Gnulib counterparts.

5098 for the default, which the user can override.
5099 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
5100 deal with LEXLIB.
5101 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
5102 didn't work if some values were cached but not others. Test for
5103 broken lex libraries like native ia64-hp-hpux11.22; see
5104 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
5105 work around the problem by preferring an empty LEXLIB to -lfl or
5106 -ll. Let the user set LEXLIB='' to indicate no library needed.
5108 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
5109 * README: Likewise.
5110 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

5205 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
5206 64-bit preprocessor ints. Check for static initialization of
5207 long long. Remove unnecessary casts.
5209 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5211 * doc/autoconf.texi (Particular Programs): Mention that
5212 @INSTALL@ and @MKDIR_P@ may vary for different output files.
5213 Reported by Alexandre Duret-Lutz.
5215 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
5217 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
5218 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
5219 Bill Northcott in
5220 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
5222 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
5224 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
5225 pacify insanely picky compilers. Problem reported by Eric Blake.
5227 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
5228 longer supported by Sun.
5230 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
5232 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
5233 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
5234 -Wundef -Werror". Problem reported by David Fang in
5235 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
5236 * doc/autoconf.texi (Header Templates, Default Includes):

5238 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
5239 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):
5240 (Present But Cannot Be Compiled, Preprocessor Symbol Index):

5251 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
5252 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
5253 this.
5255 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
5257 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5258 problems with arg script text that doesn't end in newline, and
5259 with '-e a...'. Problems reported by Ralf Wildenhues.
5261 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
5263 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
5264 check for libXt by a check for libX11.
5266 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5268 * doc/autoconf.texi (config.status Invocation): Adjust according
5269 to last change.
5271 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5273 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
5274 --help' should mention that `--version' outputs configuration
5275 settings. Report by Bruno Haible.
5277 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
5279 Fix test suite failures reported by Pierre in
5280 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
5281 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
5282 the compiler created a file "b.out" when it didn't create anything
5283 at all.
5284 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
5285 Discard stderr too, when invoking the test script.
5287 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
5289 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
5290 in the restoring of the werror flag.
5292 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5294 * doc/autoconf.texi (Volatile Objects): Be even a little
5295 less skeptical about "volatile", after discussion with
5296 Bruno Haible on bug-gnulib.
5297 (Limitations of Usual Tools): Warn about sed stripping
5298 leading white space from text. From Bruno Haible.
5300 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5302 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5303 compiler complains about it, even if things works after the
5304 complaint. Problem reported by Peter O'Gorman.
5306 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5307 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5308 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5310 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5312 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5313 after -R regardless of host. Patrick Welche reports that this
5314 fixes things on NetBSD 3.99.
5316 * NEWS: Recommend M4 1.4.5.

5320 to match M4 1.4.5.
5322 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5324 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5325 under AC_C_VOLATILE.
5326 (Volatile Objects): Be a little less skeptical about what
5327 "volatile" means. Derived from thoughts by Ben Pfaff in
5328 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5330 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5332 * doc/autoconf.texi: Fix some typos.
5334 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5336 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5337 more globally, since the 2006-06-30 patch didn't suffice. Problem
5338 reported by Keith Marshall. Also, don't bother with builddir2,
5339 since it shouldn't be needed any more.
5341 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5343 * doc/autoconf.texi (Generic compiler characteristics):
5344 Document AC_COMPUTE_INT. Fix wrong statements on Default
5345 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5347 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
5348 (_AC_COMPUTE_INT): Add obsoletion warnings.
5349 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
5350 AC_COMPUTE_INT.
5352 * NEWS: Document change.
5354 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5356 * doc/autoconf.texi (Volatile Objects): New section.
5358 * NEWS: Document previous change.
5360 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5362 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5363 Require that long long int be at least 64 bits wide. C99 requires
5364 this and enough programs depend on it so we should check for it.
5365 Bruno Haible reports in
5366 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5367 that long long int is 32 bits wide with some nonstandard compilers.
5368 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5370 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5372 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5373 to a nonexistent file, so that we don't have to worry about
5374 a local site configuration that doesn't use /usr/local.
5375 Problem reported by Keith Marshall in
5376 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5378 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5380 * doc/autoconf.texi: Be more consistent about using @acronym with
5381 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5382 quite right (it talked about "OSF/Tru64", even though the
5383 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5384 and it even mentioned "OSF 4"!) and at this point there's little
5385 reason to talk about OSF any more, since it died in 1994.
5386 (Specific Compiler Characteristics): Simplify example of
5387 negative-size array.
5388 (File Descriptors): Reorder to make the text flow better.
5389 Remove joke about "appreciate the various levels"; I didn't get it.
5390 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5391 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5392 (File Descriptors, Limitations of Usual Tools):
5393 Tone down the advice against renaming or removing open files.
5394 (Limitations of Usual Tools): Add a new section, on 'rm'.
5396 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5398 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5399 -lXt in LIBS, idea from Karsten Hopp; this was due since
5400 this change:
5402 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5403 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5404 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5405 (which belong to Xt, not X itself). See Debian bug 327655.
5407 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5409 * configure.ac (AC_INIT): Bump to 2.60a.
5410 * NEWS: Update.
5412 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5414 Version 2.60.
5416 * configure.ac, NEWS: Update.
5418 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5420 * config/texinfo.tex: Sync from upstream.
5422 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5423 quadrigraph correctly in traces.
5425 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5426 Fix typos.
5428 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5429 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5430 not defined.
5431 * doc/autoconf.texi (Changed Directory Variables): New node,
5432 to document the whole `datarootdir' business a bit better.
5433 * NEWS: Update.
5434 * tests/torture.at (datarootdir workaround): Extend test.
5435 Prompted by report by Alexandre Julliard.
5437 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5439 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5440 when using default mode of IBM C 6 for AIX. Problem and two-line
5441 fix reported by Larry Jones.
5443 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5445 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5446 about literal '${datarootdir}' if a definition is found in the
5447 output file.
5449 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5451 * NEWS: Use "M4" rather than "m4" when appropriate.
5452 Problem reported by Eric Blake.
5453 * doc/autoconf.texi: Likewise.
5454 Use @acronym around BSD, GCC, and GNU when appropriate.
5455 (Why GNU M4): Renamed from "Why GNU m4".
5456 (Redefined M4 Macros): Mention that Posix
5457 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5458 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5459 to int.
5461 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5463 * bin/autom4te.in (handle_output): Do not forbid the empty
5464 pattern.
5465 * tests/tools.at (autoconf: the empty token): New test.
5467 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5469 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5470 calls, so that we do not care whether they are LIFO or FIFO;
5471 in the m4_wrap, do not check which diversion is the topmost
5472 one, just check that the stack is balanced at the end.
5473 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5474 base diversion forever--pop the previous diversion before
5475 opening the new one; consequently, remove the m4_wrap call.
5476 * lib/autotest/general.m4 (AT_INIT): Likewise.
5477 * tests/m4sugar.at: Do not use
5478 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5480 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5481 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5483 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5484 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5485 Rework example of m4wrap token-pasting trouble so that it doesn't
5486 care whether it's LIFO or FIFO.
5487 Fix some "contrary to"s that are awkward in English.
5489 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5491 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5492 to `yes' instead of `int$1_t' if the type is found, for more
5493 consistent configure output (where $1 is the number of bits).
5494 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5495 Suggested by Bruno Haible.
5497 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5498 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5499 with system headers. Report by Bruno Haible.
5501 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5503 * config/config.guess, config/config.sub: Sync from upstream.
5505 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5506 in order to avoid picking up an older installed frozen m4sh.m4f.
5507 Besides an outdated shell startup, this could have been created
5508 by an earlier M4 version with incompatible frozen file format.
5510 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5512 * README: Recommend m4 1.4.4 instead of 1.4.3..
5513 * doc/autoconf.texi: Likewise.
5514 (Special Chars in Names): Say that $(.FOO) is portable, as
5515 suggested by Stepan Kasal.
5516 (Installation Directory Variables, Build Directories):
5517 (Automatic Remaking, Subdirectories, Fortran Compiler):
5518 (Making testsuite Scripts, Defining Directories):
5519 Quote variable usages better.
5520 (Making testsuite Scripts): Add clean-local rule to makefile
5521 snippet, by Eric Blake.
5522 (Installation Directory Variables): Fix table item font.
5523 Reword slightly to clarify. Generalize advice about
5524 not using special characters to include all file-related
5525 vars, not just VPATH.
5526 (Special Chars in Variables): Warn about special characters in
5527 $(srcdir) too.
5528 (Assignments): Clarify default-value example as suggested by
5529 Ralf Wildenhues in
5530 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5531 (Special Shell Variables): Note leading ./ or ../, as suggested
5532 by Eric Blake.
5533 (Limitations of Builtins): Under cd, warn about CDPATH.
5534 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5535 Ralf Wildenhues.
5537 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5539 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5540 `@var', for texi2html.
5541 (Systemology): Some more word wrapping, for DVI output.
5542 (autom4te Invocation): The short option for `--melt' is `-M',
5543 not `-m'.
5545 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5547 * doc/autoconf.texi: More formatting and English tweaks,
5548 many suggested by Ralf Wildenhues.
5549 Reword to avoid "@code{...}'s" and the like, since it's ugly
5550 with Emacs info mode. discontents -> woes.
5551 Put a few "will"s back. time stamp -> timestamp.
5552 side-effect -> side effect.
5554 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5556 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5557 Warn about $@ not persisting. Problem reported by Julien Danjou in
5558 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5559 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5560 Mention other special chars, too.
5562 2006-06-14 Eric Blake <ebb9@byu.net>
5564 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5566 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5568 * doc/autoconf.texi: Some systematic minor improvements, as
5569 follows. Use "makefile" when talking about makefiles
5570 generally (which might be named "makefile" or "Makefile" or even
5571 "foo.mk"), "Makefile" when talking about a specific makefile
5572 called "Makefile". This unclutters the text from weird quotes
5573 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5574 values" rather than "@var{foo}s" and similar constructs containing
5575 "}s". Use "Make rules" rather than "Makefile rules". Minor
5576 English-language improvements. Change the prefix "sub-" to "sub"
5577 and "re-" to "re".
5578 Put blank lines around examples more consistently.
5579 Avoid "rather" and "very" as intensifiers.
5580 Avoid "will" as an auxiliary.
5581 (Limitations of Make): Split this node into....
5582 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5583 (Leading _ in Macro Names, Backslash-Newline-Newline):
5584 (Backslash-Newline Comments, Long Lines in Makefiles):
5585 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5586 (obj/ and Make, make -k Status, VPATH and Make):
5587 (VPATH and Double-colon, $< in Explicit Rules):
5588 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5589 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5590 New nodes, resulting from splitup of Limitations of Make.
5591 All cross-references changed. Raise the top node from
5592 a section to a chapter, and all subnodes accordingly.
5593 Redo the introductory wording to match the new organization.
5594 (Installation Directory Variables): Use an example that is
5595 closer to what Autoconf actually does. Mention that VPATH's
5596 value should not contain metacharacters or white space.
5597 (Fortran Compiler): Fix a VPATH bug in an example.
5598 (Leading _ in Macro Names): Mention that this problem is no longer
5599 of practical concern.
5600 (VPATH and Make): Reword the advice to make it clearer
5601 that Autoconf and Automake support VPATH in non-GNU make, but
5602 many packages have bugs in this area.
5603 ($< in Explicit Rules): Refer to Build Directories rather
5604 than using a (non-VPATH-safe) example.
5605 (Automatic Rule Rewriting): Mention the sort of disaster that
5606 can ensue with Solaris-style rule rewriting with VPATH.
5608 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5610 * doc/install.texi (Compilers and Options): Weaken the
5611 suggestion to use GNU make for VPATH builds.
5613 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5614 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5616 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5617 in regular expression.
5619 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5621 * doc/autoconf.texi (Installation Directory Variables):
5622 Drop extra @samp from `@table @samp' item.
5623 (Limitations of Usual Tools): Comment fix.
5624 Do not nest @samp just to point to other table items.
5625 (Writing testsuite.at) <AT_CHECK>: The second argument to
5626 `@dvar' is already @samp'ed.
5627 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5628 do not use @var in the second argument.
5630 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5632 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5633 $as_shell.exe too. Problem reported by Andreas Buening in
5634 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5636 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5638 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5639 `unused variable' compiler warning, for `-Wall -Werror'.
5640 Reported by Jaap Haitsma in
5641 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5643 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5645 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5646 case the compiler dumps core. Problem reported for
5647 OpenServer 5.0.7 by Tim Rice in
5648 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5649 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5650 Likewise.
5652 2006-06-06 Tim Rice <tim@multitalents.net>.
5654 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5655 "ERROR" only shows up in "make check" output if there is an
5656 error.
5658 2006-06-06 Eric Blake <ebb9@byu.net>
5660 * tests/tools.at (automatically allowed tokens): Fix typo.
5662 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5664 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5666 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5667 typically overflows on x86 CPUs, even though the C standard
5668 requires otherwise.
5670 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5672 * configure.ac (AC_INIT): Bump to 2.59e.
5673 * NEWS: Update.
5675 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5677 Version 2.59d.
5679 * config/texinfo.tex: Sync from upstream.
5681 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5682 seen, invoke libtoolize with `--ltdl' argument.
5683 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5684 * NEWS: Update.
5685 Suggested by Eric Blake.
5687 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5689 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5690 reported by Ralf Wildenhues.
5691 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5693 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5695 * THANKS: Update.
5697 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5699 * doc/autoconf.texi: Modernize some of the references to Solaris.
5701 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5703 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5704 message issued by AC_REQUIRE.
5705 * tests/m4sugar.at: Check m4_require's error message.
5706 * tests/base.at: Check AC_REQUIRE's error message.
5707 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5708 to...
5709 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5710 AT_CHECK_M4.
5711 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5712 `expout' as the last parameter.
5713 * tests/tools.at: Adapt to the above change.
5715 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5717 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5718 information about race-free implementations of mkdir.

5724 * bin/autom4te.in (help): Likewise.
5725 * doc/autoconf.texi (autom4te Invocation): Likewise.
5727 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5729 * NEWS: GNU make now recommended for VPATH builds.
5730 Mention that some macros are now documented to be obsolescent.
5731 * doc/autoconf.texi:
5732 Prefer "current" to "modern" to describe
5733 currently-used (albeit perhaps old-fashioned) hosts.
5734 Mention which ancient features no longer need to be worried about.
5735 setgid -> set-group-ID
5736 setuid -> set-user-ID (these are the Posix terms)
5737 Fix some misuses of "only".
5738 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5739 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5740 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5741 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5742 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5743 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5744 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5745 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5746 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5747 Mention that these macros are obsolescent.
5748 (Installation Directory Variables): shall -> should
5749 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5750 Mention that it's now safe to use 3 and 4.
5751 (Limitations of Usual Tools): cp -r is now specified by Posix.
5752 Omit longwinded and obsolescent discussion of cp -f.
5753 Modernize discussion of expr, ls.
5754 (Limitations of Make): Modernize discussion of VPATH builds.
5755 Mention $? as a workaround in some cases.
5756 * doc/install.texi (Basic Installation):
5757 Mention "./configure; make; make install" first. Be more
5758 specific about why this file is generic. Remove unnecessary
5759 parens. Remove misleading "only". Remove obsolete advice
5760 about csh. Don't say "configure" takes awhile; say it
5761 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5762 and CC=c99 rather than CC=c89, as these are blessed by current
5763 Posix. Recommend GNU make if doing a VPATH build.
5765 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5767 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5768 examples involving shell prompts.
5770 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5771 and Paul Eggert <eggert@cs.ucla.edu>
5773 * doc/autoconf.texi (Here-Documents): Add details about the
5774 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5775 use "here-documents" instead of "here documents".
5777 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5779 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5781 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5783 * doc/autoconf.texi (File System Conventions): Warn about ":"
5784 anywhere in directory names.
5786 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5788 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5789 about quoting the case statement, just in case.
5790 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5791 was fixed in ksh93g; reported by Ralf Wildenhues.
5793 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5795 * doc/autoconf.texi (System Services): Do not document
5796 overriding EXEEXT via ac_cv_exeext=ext.
5797 (Particular Programs) <AC_PROG_MKDIR_P>:
5798 Document that ${MKDIR_P} understands --.
5799 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5800 comment.
5802 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5804 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5805 argument with leading hyphen. Problem reported by Paul Eggert.
5807 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5809 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5810 about quoting ac_try: quote all of it, if any of it seems suspicious.
5811 This means we don't have to worry about ${ or sed any more.
5812 Also, double-quote the case statement, to work around misuses via
5813 underquoting as reported by Ralf Wildenhues in
5814 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5815 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5816 undocumented and dangerous macro.
5817 Problem reported by Ralf Wildenhues in
5818 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5820 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5822 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5823 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5824 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5826 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5828 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5829 since evidently some packages rely on the old, broken behavior.
5830 Problem reported by Ralf Wildenhues in
5831 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5832 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5833 pre-2006-05-26 definitions, but leave in the comments that
5834 these macros are dangerous and should not be used.
5835 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5836 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5837 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5838 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5839 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5841 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5843 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5844 the use of 'tr', since this is our only use of 'tr'.
5846 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5847 and Paul Eggert <eggert@cs.ucla.edu>
5849 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5850 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5852 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5854 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5855 the output file in the `${datarootdir}' test.
5857 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5858 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5860 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5861 mention of `datarootdir' in the input file(s), but literal
5862 `${datarootdir}' in the output file, and we haven't warned yet,
5863 then warn as well: the user may have (erroneously) used
5864 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5865 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5866 * tests/torture.at (datarootdir workaround): Extend this test.
5867 * NEWS: Update.
5869 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5870 and Paul Eggert <eggert@cs.ucla.edu>
5872 * doc/autoconf.texi (autoheader Invocation): The first argument to
5873 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5874 alternatives and clear up the language a bit.
5876 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5878 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5879 ac_config_guess, ac_config_sub, ac_configure.
5880 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5881 Fix typo that prevented an unnecessary space from being removed.
5882 Problems reported by Ralf Wildenhues in:
5883 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5885 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5887 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5888 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5889 Don't use the term "thread-safe" to talk about mkdir race
5890 conditions, since the problem is more a process than a thread
5891 issue. Problem reported by Stepan Kasal in:
5892 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5893 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5894 the test for 'install' more closely. Look at MKDIR_P first.
5895 Look in the PATH, and at /opt/sfw/bin.
5896 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5897 Don't bother to try mkdir -p, since we already check mkdir --version;
5898 just look at the version number. (There's no easy way to check
5899 for race-free implementations.)
5900 * tests/tools.at (autoconf: subdirectories): Adjust to above
5901 changes, since MKDIR_P now might end in "/mkdir -p".
5903 * doc/autoconf.texi (autoheader Invocation): Mention that the
5904 first arg of AC_DEFINE_UNQUOTED must be a literal.
5905 Problem reported by Ben Pfaff in
5906 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5908 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5909 * doc/autoconf.texi (Special Chars in Variables): New section.
5910 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5911 (Installation Directory Variables): Quote $(datadir) better.
5912 (Limitations of Builtins): Describe some of eval's trickiness.
5914 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5915 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5916 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5917 in front of every arg, not just trailing args. Quote apostrophes.
5918 (_AC_EVAL_ECHO): New macro.
5919 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5920 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5921 removed.
5922 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5923 exposed by quoting of eval argument. Put the command on line line
5924 so it logs better.
5925 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5926 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5927 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5928 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5929 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5930 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5931 Use eval more safely.
5932 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5933 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5934 to be replaced.
5935 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5936 lines, exposed by quoting of eval argument.
5938 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5939 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5941 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5942 initialization of `ac_cv_exeext', do not override it if it was
5943 already set, unless it was set to `no', for compatibility with
5944 Autoconf-2.13, and comment this.
5945 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5946 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5947 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5948 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5949 Document that this test may be overridden by setting
5950 `ac_cv_exeext'.
5952 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5954 Revert these two patches:
5956 2006-04-06 Eric Blake <ebb9@byu.net>
5957 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5958 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5959 2006-04-01.
5961 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5962 Clean up _AC_COMPILER_EXEEXT* macros.
5963 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5964 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5965 ac_file to the name of the default output file and call
5966 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5967 initial `rm' of the candidate files...
5968 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5969 the same list in subsequent `rm' calls, and for the temporary
5970 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5971 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5972 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5973 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5974 no longer needed) by libtool. Make it a cache check.
5975 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5976 copied here by mistake.
5977 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5978 _AC_COMPILER_EXEEXT.
5979 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5980 _AC_COMPILER_OBJEXT directly.
5981 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5983 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5985 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5986 Fix description of how the buggy `sed' works.
5988 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5990 Sync from Automake:
5992 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5993 ENOLCK. Only mention `make -j' when applicable. Only raise
5994 fatal errors when `make -j' is involved. Improve error message.
5996 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5998 * doc/autoconf.texi (Here-Documents): We now know more about
5999 the variable expansion in here documents bug.
6000 Thanks to Tim Rice and Stepan Kasal.
6002 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6003 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6005 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6007 * tests/autotest.at (Multiline command from M4 expansion):
6008 No failure to be expected if the shell quotes newlines in
6009 commands in the `set -x' output. Report by Tim Rice.
6010 * THANKS: Update.
6012 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6014 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6015 expansion in the here-documents used by config.status, as that
6016 runs afoul of the Korn shell version M-12/28/93d bug described in
6017 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6018 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6019 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6021 2006-05-23 Jim Meyering <jim@meyering.net>
6023 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6024 Fix typo introduced with 2006-04-02 change. It reversed the sense
6025 of the test.
6027 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6029 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6030 ac_dB slightly, to save bytes in the script.
6031 Max out at 50 lines, rather than 96; this is more likely
6032 (though not guaranteed) to avoid obscure 'sed' failures.
6034 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6036 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6037 `tr -d -' as bad option argument. Work around this by deleting
6038 an unrelated character.
6039 Report by Tim Rice <tim@multitalents.net>.
6041 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6042 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6043 Stepan Kasal <kasal@ucw.cz>
6045 * doc/autoconf.texi (Particular Programs): Do not promise that
6046 we always prefer the GNU version of the program, and that we
6047 search according to PATH; both rules can have exceptions.
6048 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6049 AC_PROG_SED. Move descriptions of limitations
6050 to the Limitations of Usual Tools section.
6051 (Limitations of Usual Tools) <sed>: Mention script length
6052 limitations with Solaris /usr/ucb/sed.
6053 <grep>: Fix wording for empty alternative. Mention that -c and
6054 -l should not be combined, and that -E and -F should not be
6055 combined.
6057 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6058 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6060 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6061 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6063 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6065 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6066 AC_DEFINE is now passed to m4_pattern_allow.
6067 * NEWS: Mention that; likewise for AC_SUBST.
6068 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6069 the parameter to m4_pattern_allow.
6070 * tests/tools.at: Add a check for that.
6072 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6074 * lib/autoconf/status.m4: Fix typos.
6076 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6078 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6079 only the files that this macro generates.
6081 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6083 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6084 the HP-UX sed limitation of 99 commands, labels do not count.
6085 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6086 in the comment.
6087 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6089 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6091 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6092 Import the following fix from coreutils:
6094 2006-01-13 Jim Meyering <jim@meyering.net>
6096 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6097 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6098 not double-quote uses of that variable, to accommodate the rare
6099 case in which getmntent is available in none of the libraries
6100 checked. This happens at least on FreeBSD 5.0.
6102 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6104 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6105 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6106 some other programs unwisely rely on these undocumented vars.
6107 But put in warning comments about them.
6108 Problem reported by Ralf Wildenhues in
6109 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6110 * NEWS: Document that these variables are intended to go away.
6112 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6114 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6115 and set the language to C++ (analogous to the equivalent Fortran
6116 tests).
6118 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6119 * doc/autoconf.texi (C++ Compiler): Document it.
6120 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6121 * NEWS: Update.
6123 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6125 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6126 that caused config.status to generate 100-command sed scripts; the
6127 portable limit is 99.
6129 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6131 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6132 variable `ac_d' instead of `d' to avoid infringing namespace.
6133 Report by Ralf Menzel.
6135 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6137 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6138 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6139 * tests/tools.at (autoconf: subdirectories): New test, taken from
6140 the corresponding problem report by Ralf Wildenhues in:
6141 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6143 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6144 Quote some uses of shell variables if they might suffer unexpected
6145 globbing. This doesn't fix all instances of quoting problems that
6146 I found, just the easy ones that look safe.
6147 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6148 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6149 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6150 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6151 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6152 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6153 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6154 Likewise.
6155 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6156 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6158 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6160 * bin/autoreconf.in ($help): Reword according to the manual.
6161 Suggested by Olly Betts.
6163 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6164 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6166 * bin/autoreconf.in: Pass the directory argument to
6167 `require_configure_ac'. Fix comment.
6168 * tests/torture.at (Configuring subdirectories): Expose this.
6169 Reported by Olly Betts.
6171 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6173 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6174 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6175 Automake as follows:
6177 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6178 `$configure_in' instead of `configure.in', to preserve
6179 directory component.
6181 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6183 * config/config.guess, config/config.sub, config/texinfo.tex,
6184 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6186 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6188 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6189 test for C99 conformance; (bool) 0.5 is an integer constant
6190 expression, but (bool) -0.5 is not. Problem reported by Fedor
6191 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6193 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6195 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6196 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6197 Warn about obsolete install-sh files. Remove stray sentence
6198 fragment and fix cross reference.
6199 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6200 install -d; this undoes the 2006-05-10 change.
6201 (MKDIR_P): Mark with AN_MAKEVAR.
6202 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6203 that we don't require $INSTALL to be thread-safe. Move comments
6204 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6205 of AC_PROG_INSTALL. Output a message saying that we're checking
6206 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6207 MKDIR_P instead of AC_SUBST.
6208 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6209 Special magic for MKDIR_P, too.
6210 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6211 a dnl.
6212 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6214 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6216 Sync from Automake, as follows:
6218 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6219 * config/install-sh: Initialize IFS, so field splitting isn't
6220 turned off later.
6221 * config/mkinstalldirs: Likewise.
6222 * config/missing: Remove superfluous quotes. Replace all uses of
6223 `[' by `test', for consistency, and for..
6224 * config/missing (sed_minuso, sed_output): New variables.
6225 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6226 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6227 Fixes `missing' to detect `--output' for help2man. Fixes
6228 PR automake/483. Report by Dennis J. Linse.
6229 (autom4te): Document in `missing --help'.
6231 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6233 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6234 * config/install-sh: Don't use 'path' to talk about file names,
6235 as per GNU coding standards. Close a race condition reported by Ralf
6236 Wildenhues and Stepan Kasal. There is still a race condition
6237 on hosts that predate Posix 1003.1-1992, but we can't help this.
6238 Don't mishandle weird characters like space on pre-Posix hosts.
6239 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6240 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6241 AC_PROG_MKDIR_P from AS_MKDIR_P.
6242 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6243 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6244 earlier editions are not (including Automake 1.8.3).
6245 Do not suggest mkinstalldirs for thread-safety.
6246 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6247 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6248 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6249 presence of special characters and race conditions.
6250 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6251 in Autoconf's name space.
6253 2006-05-10 Bruno Haible <bruno@clisp.org>
6254 and Paul Eggert <eggert@cs.ucla.edu>
6256 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6257 from Automake with minor changes.
6258 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6260 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6262 * config/install-sh: Update to Automake CVS version, as follows:
6263 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6264 * lib/install-sh: Simplify the expr implementation of dirname.
6265 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6266 * lib/install-sh: Handle --, and diagnose unknown options.
6268 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6270 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6271 `./autom4te' to create `./testsuite', since the `all' target
6272 will ensure its presence, but `installcheck' should not create
6273 the uninstalled wrappers.
6275 * tests/torture.at (Unusual Automake input files): Skip if we
6276 detect automake < 1.8.
6278 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6280 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6281 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6282 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6283 * NEWS: Update.
6285 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6287 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6288 munge (multiple) white space and other oddities.
6289 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6290 single quotes in variable assignment.
6291 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6292 and similar failures by adding multiple spaces, tabs, and other
6293 special characters.
6294 Report and different test suggested by Francesco Romani
6295 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6297 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6298 single quotes, we only need to search for single quotes; this
6299 both simplifies the search pattern, and makes us less
6300 susceptible to `echo' variations for arguments not containing
6301 single quotes.
6302 (_AC_ARG_VAR_VALIDATE): Likewise.
6304 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6306 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6307 `$*' and IFS concatenation issue with traditional shells and
6308 bash-2.04. Report by Seanster@Seanster.com.
6310 2006-05-03 Bruno Haible <bruno@clisp.org>
6312 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6313 precisely which Mac OS X versions have the od problem.
6315 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6317 * doc/autoconf.texi: Use @option systematically.
6319 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6320 and Bruno Haible <bruno@clisp.org>
6322 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6323 about 'od'.
6324 (Integer Overflow): Mention the special case of integer division
6325 overflow.
6327 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6329 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6330 traditional shells like the Solaris one that do not use the
6331 first IFS character for assembling `$*'.
6332 Prompted by a related report from autoconf_bug@nro.ca.
6334 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6335 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6337 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6338 Mention more problems with the -e option.
6340 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6342 * NEWS: Typo.
6343 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6345 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6346 in URLs to improve DVI formatted output (requires texinfo 4.6).
6347 (System Services, Systemology, Shellology): Likewise.
6348 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6349 output.
6351 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6352 continuous text.
6353 (Runtime): Fix macro argument names to match description:
6354 `action-if-found' -> `action-if-true' and similarly.
6355 (Obsolete Macros): Likewise.
6356 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6357 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6358 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6360 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6362 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6364 * ChangeLog: Typo.
6365 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6366 DVI output.
6368 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6370 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6371 /bin/sh set unsorted output.
6372 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
6373 * tests/local.at: Likewise.
6375 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
6377 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6378 (Integer Overflow, Null Pointers, Buffer Overruns):
6379 (Floating Point Portability, Exiting Portably): New sections.
6380 (Writing Test Programs): Fix some langauge. Recommend exiting
6381 with status 1, not merely nonzero. Clarify exit declaration.
6382 (Run Time): Move C exit status stuff to new Exiting Portably section.
6383 (Systemology): Mention Posix and levenez. Update v7 reference.
6384 (Portable Shell): Mention the Posix shell.
6386 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6388 * bin/autoconf.as (me): Replace by as_me.
6390 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6392 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6393 since as_me isn't set yet.
6395 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6397 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6398 a few minor bugs in this area.
6400 * doc/autoconf.texi (Programming in M4sh): Comment out the
6401 documentation of AS_BASENAME, for now.
6402 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6403 (Limitations of Builtins) <basename>: Do not refer to
6404 AS_BASENAME.
6405 * bin/autoconf.as (me): Don't use AS_BASENAME.
6406 (dir): Remove the unused variable.
6407 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6408 AS_DETECT_REQUIRED. All uses changed.
6409 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6410 All uses changed.
6411 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6412 (AS_BASENAME): Use "basename --" to protect against leading "-".
6413 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6414 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6415 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6416 (_AS_DIRNAME_PREPARE): Likewise.
6417 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6418 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6419 (AS_DIRNAME): Use "dirname --".
6421 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6423 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6424 of "run time" and "run-time" changed to "runtime", for consistency.
6425 * lib/autoconf/fortran.m4: Likewise (in comment).

6427 * lib/autoconf/general.m4: Likewise.
6428 * lib/autoconf/headers.m4: Likewise.
6430 * doc/autoconf.texi (Run Time): Document the exit status situation
6431 with more accuracy and detail.
6433 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6435 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6436 Archive is not officially `GNU' any more. Update URL.
6437 (Defining Directories): Likewise
6438 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6440 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6442 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6443 newline from the `trap' code to finish `config.log'; the NetBSD
6444 /bin/sh resets the exit status after an empty command, as
6445 documented in doc/autoconf.texi.
6446 Reported by Dalibor Topic <robilad@kaffe.org>.
6448 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6450 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6451 Suggested by Bruno Haible.
6453 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6455 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6456 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6457 Instead, just list the shells that we know work.
6458 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6459 changed. Be more cautious about the _cv_ variable.
6460 * tests/tools.at (Syntax of the shell scripts): Check the
6461 _cv_ variable once, at first, to avoid an internal autoconf error
6462 when sh -n does not work.
6464 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6466 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6468 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6470 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6471 use ">&-" since we're only 99.999% sure that this is portable,
6472 and since the MinGW bug is fixed in a different way.
6473 * lib/autotest/general.m4 (AT_INIT): Likewise.
6475 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6477 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6478 before opening config.log, to avoid hitting a bug on MinGW.
6480 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6482 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6483 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6484 This works around a MinGW bug reported by Eric Paire.
6485 Make sure that all writes to the log file append to it,
6486 rather than possibly losing data.
6487 * lib/autotest/general.m4 (AT_INIT): Likewise.
6489 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6491 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6492 description.
6494 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6496 * NEWS: Update.
6498 * configure.ac (AC_INIT): Bump to 2.59d.
6500 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6502 Version 2.59c.
6504 * Makefile.maint (news-date-check): Do not require a leading `*'
6505 before the release date in NEWS.
6507 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6508 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6510 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6511 the instantiated file do not contain the string 'datarootdir'
6512 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6513 @mandir@, replace the reference '${datarootdir}' by the value.
6514 * tests/torture.at (datarootdir workaround): New test.
6515 * NEWS: Advertise this temporary fixup.
6516 Based on a patch by Bruno Haible, reported and analyzed by
6517 Paul Eggert and Noah Misch.
6519 2006-04-12 Eric Blake <ebb9@byu.net>
6521 * tests/autotest.at (Debugging a failed test): Fix comment.
6523 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6525 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6526 all the changes since 2006-04-07.
6528 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6530 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6531 succeeded, but `ln -s file dir' failed, take care to remove the
6532 leftover target before the next test, to prevent its spurious
6533 failure; also make sure `ln file dir' works before selecting it.
6534 Thanks to Keith Marshall for pointing this out.
6535 * THANKS: Update.
6537 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6538 assignments in `at_debug_args', so that we put them correctly
6539 in the `run' script.
6540 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6541 Reported by Eric Blake.
6543 2006-04-11 Eric Blake <ebb9@byu.net>
6545 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6546 top-level tests after micro-suite has been run. Used in...
6547 (Debugging a successful test, Debugging script and environment),
6548 (Debugging a failed test): ...these new tests. The first of these
6549 is fixed by...
6550 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6551 macro, split out from...
6552 (AT_INIT): ...here, so that using -d also generates a run script.
6553 Document that -d inhibits top-level logging.
6554 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6555 inhibits top-level logging; debug scripts are created.
6557 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6558 check.
6559 * tests/autotest.at (Empty test, Empty check): New test to check it.
6561 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6562 from gcc.
6564 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6566 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6567 the files if a problem appears. Make the empty *.at files
6568 read-only, too. Proposed by Ralf Wildenhues.
6570 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6572 * config/Makefile.am: Add comment to force updated Makefile.in.
6574 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6575 space only patch to this file, this patch causes the Makefile.in
6576 files that include freeze.mk to be updated, and thus have a
6577 newer time stamp again, which in turn makes a pristine CVS
6578 checkout have correct time stamps.
6580 * Makefile.maint (cvs-sv): New macro, to be used..
6581 (config.guess-url_prefix, config.sub-url_prefix)
6582 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6583 point to CVS text checkout of Gnulib files.
6584 (copyright-check): Bump current year.
6585 (announcement): Do not hard-wire `./announce-gen'.
6586 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6587 correctly.
6588 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6589 `chmod +x'.
6590 (wget_files): Update config.guess, config.sub, texinfo.tex by
6591 `wget-update', now that their URLs work again.
6593 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6595 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6596 Problem noted by Paul D. Smith.
6598 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6600 * doc/autoconf.texi: Remove unused words from word list.
6601 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6602 .x-sc_trailing_space: New files.
6604 * doc/standards.texi: Sync from gnulib.
6606 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6607 `LIBOBJDIR' as experimental.
6609 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6610 with a target directory; it's internally implemented as `cp'
6611 anyway, but since Autoconf advertises the possibility to use
6612 a target directory when LN_S is `ln -s', we need to find out.
6613 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6614 analyzed by Keith Marshall <keith.marshall@total.com>.
6616 * THANKS: Update.
6618 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6620 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6621 confdefs.h as-is. In general, if it has backslash-newline or the
6622 like, then it doesn't work either to sort or to remove empty
6623 lines.
6625 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6627 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6629 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6631 * lib/autom4te.in (Automake-preselections): Preselect
6632 _AM_SUBST_NOTMAKE.
6634 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6636 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6637 apostrophe within a single-quoted string, as this is the usual
6638 tradition and is easier to read than '"'"'. Don't rely on the
6639 shell treating "$/" like '$/'. Use a more-consistent indenting
6640 style for the trap.
6642 2006-04-09 Eric Blake <ebb9@byu.net>
6644 * tests/autotest.at (Backquote command substitution),
6645 (Multiline backquote command substitution): Remove mistaken
6646 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6647 applied...
6648 (Parenthetical command substitution, Multiline parenthetical
6649 command substitution): here.
6651 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6653 Import macros from gnulib (often changing their name).

6667 (Pointers): Add Gnulib URL.
6668 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6669 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6670 Gnulib section.
6671 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6672 suggest a #define rather than a typedef for _Bool, and mention
6673 Gnulib rather than trying to substitute stdbool code.
6674 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6675 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6676 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

6679 headers too.
6680 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6681 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6682 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6683 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6684 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6685 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6686 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6687 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6688 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6689 (Coding Style). Don't mention m4_expand_once.
6690 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6691 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6692 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6693 (AC_CHECK_FUNCS): Use it.

6698 (AC_HEADER_ASSERT): New macro.
6699 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6700 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6701 Catch a bug in an HP-UX C compiler.
6702 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6703 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6704 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

6706 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
6707 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6708 New macros.
6710 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6711 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6713 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6715 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6716 of the warning introduced by the 2001-08-28 change.
6718 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

6721 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6722 variables shall be overriden by the cache.

6724 that contains braces.
6726 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6728 Revert the patch from 2006-04-01 and only improve
6729 _AS_DETECT_BETTER_SHELL:
6731 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6732 skip nonexistent directories.
6733 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6734 only shell candidates which exist.
6735 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6736 * lib/autotest/general.m4 (AT_INIT): No need to give three
6737 parameters to _AS_PATH_WALK.
6739 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6740 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6742 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6743 distinguish m4sugar macros.
6744 * tests/tools.at (autoupdating with aclocal and m4_include):
6745 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6746 test case by Noah Misch <noah@cs.caltech.edu>.
6748 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6750 Revert my change from 2006-03-17, in other words:
6751 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6752 and DUALCASE=1.
6753 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6754 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6755 it is set.
6757 2006-04-07 Eric Blake <ebb9@byu.net>
6759 * doc/autoconf.texi (Programming in M4sh): Document that
6760 AS_MKDIR_P exits the script on failure.
6761 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6763 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6765 * config/elisp-comp, config/install-sh, config/mdate-sh,
6766 config/missing, config/mkinstalldirs: Sync from Automake.
6768 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6769 from Automake.
6771 * doc/make-stds.texi: Sync from gnulib.
6773 2006-04-06 Eric Blake <ebb9@byu.net>
6775 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6776 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6777 2006-04-01.
6779 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6780 Eric Blake <ebb9@byu.net>,
6781 Paul Eggert <eggert@cs.ucla.edu>,
6782 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6784 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6785 whether `set' quotes correctly: redirect stderr of the tested
6786 `set', and use a subshell, for Ultrix; use `sed' instead of
6787 `grep' for zsh `set' which may write binary output; match only
6788 at the beginning of a line, to avoid false positives.
6789 In order to avoid false positives by unrelated variables with
6790 multiline content, put the dump algorithm in a subshell and
6791 unset all variables containing newlines (except some which are
6792 special to the shell). Warn about cache variables that are
6793 unset.
6795 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6797 * config/config.guess, config/config.sub, config/texinfo.tex:
6798 Sync from upstream.
6800 * tests/mktests.sh: Reword comments.
6802 * tests/mktests.sh: Only skip internal macros starting with
6803 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6804 Update exclusion lists for the test suite to this end:
6805 (AC_ARG_VAR): Do test this now.
6806 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6807 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6808 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6809 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6811 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6812 shell issue with double-quoted command substitutions of native
6813 commands.
6814 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6815 Marshall.
6817 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6820 (sc_cast_of_x_alloc_return_value): Likewise.
6821 (sc_cast_of_alloca_return_value, sc_error_exit_success)

6823 (m4-check): Likewise.
6824 (sc_system_h_headers): Do not print rule on execution.
6825 (sc_tight_scope): Do not fail for non-existing `src' directory.
6826 (sc_changelog): Skip the Copyright footer.
6827 * lib/autoconf/lang.m4: Remove trailing space.
6829 * lib/autoconf/status.m4: More replacements to
6830 <tab><space> where this makes sense.
6832 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6834 * tests/Makefile.am (maintainer-check-posix):
6835 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6837 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6838 ac_config_<foo>s again, sometimes normalized, sometimes not.
6839 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6840 (AC_CONFIG_COMMANDS): Do not do so here.
6841 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6842 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6843 2005-07-25 rewrite. Noticed by Noah Misch.
6845 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6846 _AC_PRESERVE_HELP_ORDER, ...
6847 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6849 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6850 inside m4_expand_once; it is redundant.
6852 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6853 for --help from Cygnus `configure.'
6855 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6857 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6858 on a patch proposed by Ralf Wildenhues.
6860 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6862 * lib/autoconf/status.m4: Replace <space>''<tab> with
6863 <tab><space> where this makes sense.
6865 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6866 Noah Misch <noah@cs.caltech.edu>
6868 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6869 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6870 * doc/autoconf.texi (Help Formatting): New node.
6871 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6873 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6875 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6876 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6877 lib/autoconf/types.m4, lib/autotest/general.m4,
6878 tests/mktests.sh, tests/torture.at: White space cleanup:
6879 remove some SPACE before TAB, or add quoting ('' or @&t@).
6881 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6883 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6885 2006-04-05 Eric Blake <ebb9@byu.net>
6887 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6888 empty test suite works.
6889 * tests/autotest.at (Empty test suite): Remove xfail.
6891 2006-04-05 Noah Misch <noah@cs.caltech.edu>
6893 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
6894 TAGS to ac_config_<foo>s.
6895 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6896 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6897 normalizing it, consistent it with previous releases.
6898 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6900 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6902 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6903 Use simplified args that Eric Blake originally suggested.
6905 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6907 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6908 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6909 Use 'comm' rather than N instances of grep; this also fixes a bug
6910 whereby substrings were incorrectly matched, causing us to not
6911 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6912 (exclude_list): Exclude empty macros.
6913 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6915 Use awk rather than grep -E or egrep, to avoid
6916 portability problems with regular expressions containing newlines.
6917 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
6918 Switch from grep to awk syntax.
6919 (ac_exclude_script): Renamed from ac_exclude_egrep.
6920 (au_exclude_script): Renamed from au_exclude_egrep.
6922 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6924 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6925 a subdirectory subject to Cygnus `configure'.
6926 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6928 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6929 report request when we have no AC_PACKAGE_BUGREPORT.
6931 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6933 * THANKS: Update.
6935 * tests/mktests.sh: Update copyright year in the header of the
6936 generated files.
6938 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6939 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6940 typedef'ed restricted pointer, to catch a compiler bug on
6941 HP-UX 11.x, and fix warnings so it passes with -Werror.
6942 (_AC_PROG_CC_C99): Likewise.
6943 Reported by Albert Chin <china@thewrittenword.com>.
6944 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.
6946 2006-04-03 Noah Misch <noah@cs.caltech.edu>

6998 ac_file to the name of the default output file and call
6999 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7000 initial `rm' of the candidate files...
7001 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7002 the same list in subsequent `rm' calls, and for the temporary
7003 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
7004 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
7005 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7006 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7007 no longer needed) by libtool. Make it a cache check.

7084 2006-04-01 Stepan Kasal <kasal@ucw.cz>
7086 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
7087 switch all of them on and of when necessary. Fixes the bug when
7088 m4sugar macros (e.g., m4_define) were expanded after the first
7089 automatic update (e.g., after AC_PREREQ or AC_INIT).
7091 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>
7093 * doc/autoconf.texi (Programming in M4sh): Sharpen the descriptions

7264 * tests/autotest.at (Keywords): Renamed to..
7265 (Keywords and ranges): .. this. Extended to make sure negated
7266 keywords, keywords taken from AT_SETUP arguments, and numeric

7286 trying to execute the command `no'.
7288 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not

7324 the obsolescent AC_HEADER_STDC.
7325 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

7343 HP-UX sed is 99 commands, not 100.
7344 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
7345 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
7346 newline for portability.
7347 * tests/torture.at (Torturing config.status): Also test 100
7348 AC_SUBST_FILE invocations. Fix test to actually verify the

7789 comparing its address. Intel's interprocedural optimization was

7808 Stepan Kasal <kasal@ucw.cz>
7810 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7811 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7812 make its content writable before removing it. Remove an errorneous
7813 comment from the end, where the logs of the failed tests are copied
7814 to the main log file.
7816 2005-09-27 Stepan Kasal <kasal@ucw.cz>

7823 problems if the testsuite were running too fast.
7825 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>

7839 suggested by Ben Elliston. Handle weird characters correctly.
7841 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7843 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7844 calls, so that the final expansion of this macro is shorter.
7845 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7846 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7847 the cleanup there. Use AS_VAR_* macros, to be more general.
7848 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7850 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7852 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7870 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7872 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7873 in the example. Reported by Bruno Haible.
7874 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7875 "if $undefined_var;" succeeds with my shell.
7877 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7878 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7879 but change the m4_divert_text to m4_divert_once.
7881 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7883 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7884 Work around bug in Solaris /usr/xpg4/bin/awk.
7885 The bug is present in at least Solaris 8 through 10.
7887 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7889 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7890 some evil values and relying on the fact that $* concatenates the
7891 parameters by the first character from IFS.
7893 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7894 Stepan Kasal <kasal@ucw.cz>

7898 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7899 Update limitations about when to call AC_CONFIG_HEADERS.
7900 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7901 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7902 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7903 ``Configuration Actions''; fix their index entries.
7905 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7906 options correctly. Process N-M as M-N if M is smaller than N.
7907 Process ranges correctly so that N-N will run only N.
7908 Sort and uniquify the tests that will be run. If there is more
7909 than one test, reinsert the banners for the tests.
7910 * tests/autotest.at (Keywords): Unmark XFAIL.
7912 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7914 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7915 before passing the macro name to AH_TEMPLATE.
7917 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7918 now opens log after option processing; in particular, --version
7919 and --help do not touch config.log.
7921 * Makefile.maint: Revert the change from 2005-08-12.
7923 2005-08-22 Stepan Kasal <kasal@ucw.cz>

7936 Prepend to LIBS, not append, in examples.
7938 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7940 When building in place, set srcdir="."; suggested by Tim Van Holder.
7942 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7943 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7944 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7945 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7946 does not mean "no --srcdir option".
7948 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7950 * tests/autoscan.at (autoscan): New file.

7959 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7960 add "2>&1"; gzip 1.2.4 prints help on stderr.
7962 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7964 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7965 was pushdef'ed twice while popped only once. Push it only once.

7975 * Makefile.maint: Update from Bison.
7977 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7978 "<tab>" in comment, so that the point is understandable.
7980 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7982 Rewrite substantial part of lib/autoconf/status.m4.
7983 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7984 and CONFIG_COMMANDS are not processed in four separate loops.
7985 Instead, there is one main loop. This alows that the common code
7986 is expanded only once, thus config.status (and configure) is smaller.
7988 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7989 the AC_LIST_FILES and cousins macros are no longer used.
7991 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7992 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7993 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7994 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7995 contain the initialization, nor the for loop, nor the associated
7996 commands; all these go to ...
7997 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7998 _AC_OUTPUT_CONFIG_STATUS.
7999 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8000 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8001 (_AC_OUTPUT_FILE): The creation of the sed script ...
8002 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8003 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8004 _AC_OUTPUT_MAIN_LOOP.
8005 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8006 _AC_CONFIG_COMMANDS): Use ...
8007 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8008 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8009 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8010 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8011 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8012 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8013 ... new macros.
8014 (_AC_CONFIG_UNIQUE): Update.
8015 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8016 Replaced by this ...
8017 (_AC_LIST_TAGS): ... new common macro.
8018 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8019 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8020 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8021 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8022 this didn't belong to the `config commands' section.
8023 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8024 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8025 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8026 to the `config commands' section either.
8027 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8028 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8030 ... and many changes to the comments nearby.
8032 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8033 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8034 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8035 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8036 (#define header templates): The comment at the top of the generated
8037 header now includes the name(s) of the source file(s).
8039 Several unrelated small changes:
8041 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8042 parameter to AC_DIAGNOSE.
8043 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8044 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8045 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8046 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8047 with AU::AC_OUTPUT.
8048 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8049 in AC_OUTPUT doesn't double-quote it either.
8050 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8051 parameters.
8053 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8055 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8056 versions of Portland Group compiler produce single- and double-quoted
8057 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8058 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8060 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8062 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8063 This is a corrected version of yesterday's patch.
8065 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8067 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8068 path, too; insert a "===" to emphasize the line.
8070 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8071 ac_cv_build_alias to ac_build_alias.
8072 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8074 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8075 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8076 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8077 (AC_ARG_VAR): ... here.
8078 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8079 target_alias.
8081 Keep a list of all precious variables and process them with one simple
8082 for loop, instead of expanding all commands, or, OTOH, complicated
8083 processing of output of "set".
8084 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8085 variable names in new macro...
8086 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8087 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8088 a loop to assign all ac_env_* and ac_cv_env_* variables.
8089 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8090 to INIT_PREPARE.
8091 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8092 its value to shell variable ac_precious_vars and call
8093 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8094 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8095 _AC_ARG_VAR_VALIDATE.
8097 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8098 and the AC_SUBSTs ...
8099 (AC_INIT): ... here.
8101 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
8102 the ac_subst_files section in config.log.
8104 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
8106 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

8111 * tests/c.at (C keywords): Test AC_C_TYPEOF.
8113 Fix problems reported by Nicolas Joly.
8114 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
8115 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8116 They are generated by the Tru64 v5.1B shell.
8118 2005-07-05 Stepan Kasal <kasal@ucw.cz>
8120 Fix my changes from 2005-07-01; reported by Noah Misch.
8121 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8122 description, the macro now accepts only a single tag.
8123 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
8125 Fix cases when the varsions of Autoconf and Autotest don't match.
8126 Reported by Noah Misch.
8127 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
8128 at_top_builddir, for compatibility with older autotest.
8129 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
8130 is not set, use at_top_builddir, for compatibility with older
8131 versions of autoconf.
8133 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8135 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8136 Problem reported by Patrick Welche.
8138 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8140 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8141 sed substitution command, so that we allow | in program prefixes
8142 and program suffixes. (& is a problem anyway; we're not fixing
8143 that here.)
8144 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8145 configure_input, top_builddir, srcdir, etc.
8146 * lib/autotest/general.m4 (AT_INIT): Likewise, for

8149 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
8151 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
8152 for loop over config.site files using `set', to allow
8153 directory names containing IFS characters.
8155 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
8157 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
8158 directories with weird names. Apparently some people like living
8159 on the edge. However, improve the test that "pwd" actually does
8160 report a name for the working directory.
8161 * NEWS: Remove the claim that we test for funny chars in dir names.
8163 2005-07-01 Stepan Kasal <kasal@ucw.cz>

8176 (Generic Functions): Mention the Gnulib project.
8177 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
8179 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8180 document to output the default config_* lists to config.status.
8181 Don't recognize option --file, if the functionality is not there.
8182 Likewise for --header; moreover, recognize --he and --h as shortcuts
8183 for --help in that case.
8185 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8186 matches the order of execution. No code changed.

8207 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
8208 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8209 (AC_SUBST): Call it.
8210 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8211 the directory specific variables; but don't call it for configure_input.
8213 2005-06-28 Derek Price <derek@ximbiot.com>
8215 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8216 addition.
8218 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8220 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8221 directory have inherent problems with special characters like spaces,
8222 due to limitations in Make syntax. Problem reported by Alexandre
8223 Duret-Lutz.
8224 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

8237 from Justace Clutter.
8238 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8239 variable into diagnostic. Make the diagnostic an error, not a warning,
8240 because we really don't support spaces and suchlike in dir names.
8241 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8242 Don't worry about backslashes in srcdir; it can't happen now.
8243 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8244 Simplify ac_optarg handling.
8245 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8253 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
8255 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8256 that '\|' is not allowed in BREs; recommend using newline separated
8257 list of patterns instead of multiple -e options.
8259 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8261 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8267 2005-06-21 Stepan Kasal <kasal@ucw.cz>
8269 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8270 b, t, r, w commands require single space, while : cannot have any.
8271 (Special Shell Variables): Fix sed code this in the example.
8272 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8273 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8275 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
8276 expand to the empty list. Don't use two pairs of m4_changequote,
8277 it's not necessary.
8279 2005-06-20 Derek Price <derek@ximbiot.com>
8281 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8283 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8285 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8286 * doc/autoconf.texi:
8287 Don't mention Solaris versions so much, if a
8288 problem is common to all extant versions of Solaris. Say "SunOS
8289 4" instead of "SunOS" for SunOS 4.
8290 (awk): Mention more of the limitations of traditional Awk.
8291 (cat): Don't talk about cat -v.
8293 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
8295 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
8296 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
8297 but the implementation is entirely different and is designed
8298 to be compatible with glibc strverscmp.
8299 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8301 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8302 on Mac OS X 10.4 reported by Peter O'Gorman in:
8303 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8304 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8305 Use shell builtins rather than 'expr', to work around expr bug.
8307 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8309 * doc/autoconf.texi: "filesystem" -> "file system".
8310 "behaviour" -> "behavior".
8311 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8312 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8313 as per POSIX.

8315 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8316 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8318 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8319 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8320 to update the man page. That way, we don't have to check in new
8321 man pages every month.
8323 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8324 quotes and backslashes. Patch from Derek Price.

8329 AS_TR_SH.
8331 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8333 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8334 -u, since it outputs chatter if the input files are the same.
8335 Problem reported by Ralf Menzel.
8337 2005-06-08 Derek Price <derek@ximbiot.com>
8339 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8340 renaming them since they are about to be redefined anyhow.
8342 2005-06-08 Derek Price <derek@ximbiot.com>
8344 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8345 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8346 Move m4_undefine to alphabetical order.
8348 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8350 * README: Recommend GNU M4 1.4.3 or later.
8351 * doc/autoconf.texi (Introduction): Likewise.
8352 Reword to avoid some formatting glitches.
8353 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8354 Clarify explanation of HP compiler bug.
8355 Redo example output tp match current CVS snapshot.
8356 Use @example.org in email addresses when the examples
8357 might get inadvertently cut-and-pasted into user code.
8358 Remove example of autom4te usage that doesn't seem to work now.
8359 Use modern AC_INIT (except when the example is meant to be
8360 shown with Autoconf 2.13).
8361 Update ksh info for Solaris 9 and later.
8362 KB -> kB.
8363 Modernize description of Automake versions a bit.
8364 Don't claim a future version of Autoconf is near.
8365 * doc/install.texi: Reword to avoid some formatting glitches.
8367 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8369 * doc/autoconf.texi: Add [] to examples, so that the manual
8370 follows its own advice about quoting better.
8371 Reword to avoid some formatting glitches.
8372 * doc/installt.exi: Reword to avoid some formatting glitches.
8374 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8375 Tru64 ksh pattern matching bug. Reported against Libtool by
8376 Albert Chin <libtool@mlists.thewrittenword.com> and
8377 Nicolas Joly <njoly@pasteur.fr>.
8379 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8381 m4_cdr of one-member list was [[]] (one-member list containing an
8382 empty string) instead of [] (an empty list. Callers were skewed to
8383 match this misbehaviour. As a consequence of this:
8384 - m4_foreach([x], [], [foo]) expanded to `foo', while
8385 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8386 This bug has been fixed:
8388 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8389 expand to an empty string; print error msg if called without
8390 an argument list.
8391 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8392 misbehaviour; handle [] and [[]] correctly.
8394 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8396 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
8397 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
8398 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8400 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8402 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8403 swallow records with more than 99 fields.
8404 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8405 parse the long line.
8407 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8409 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8410 swallow literals longer than 399. Reported by Ralf Wildenhues.
8411 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8412 to workaround this limitation.
8414 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8416 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8417 to gfortran, and make these the first two compiler names
8418 checked (following the general autoconf preference for gcc).
8420 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8422 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8423 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8424 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8426 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8428 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8429 expression of unbounded size when processing the --list
8430 option. This runs afoul of a limit of 399 bytes per regular
8431 expression on AIX. Problem reported by Ralf Wildenhues.
8433 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
8435 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
8436 * doc/autoconf.texi (Particular Headers): Reword example
8437 for multiline stdbool replacement.
8438 (Setting Output Variables): Reword text a bit. Don't
8439 give all the details about |#_!!_#|.
8440 Reword description of line replacement.
8442 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8444 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8445 now contain newlines, and substituted files must be referenced on
8446 a line alone; the sed scripts to substitute them are now very
8447 different.
8448 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8449 commands can be put in a sed script portably.
8450 * doc/autoconf.texi (Setting Output Variables): Document above
8451 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8452 use of multiline substitution.

8462 * tests/local.at: Don't attempt to check for negated character
8463 classes in shell scripts. The test was too brittle.
8465 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8467 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8468 * doc/autoconf.texi (Limitations of Builtins): Document this
8469 limitation.
8471 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8473 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8474 common code; used in many places in the tree.
8475 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8476 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8478 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
8480 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
8481 messages when ac_unique_file is not found.
8482 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8483 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8484 commands, for consistency with AC_MSG_ERROR and such.
8486 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8488 * bin/Makefile.am: Merge the two rules for creating scripts.

8496 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8498 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8499 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8500 (ac_top_builddir): ... this ...
8501 (ac_top_build_prefix): ... to this; the old name is also kept, for
8502 backward compatibility.
8503 (ac_top_builddir_sub): New variable, without the trailing slash,
8504 always nonempty.
8505 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8506 * doc/autoconf.texi (Configuration Actions): Rename
8507 ac_top_builddir to ac_top_build_prefix.
8508 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8509 at_top_builddir to at_top_build_prefix.

8514 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8515 of confdefs.h .
8517 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8519 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8520 argument to m4_foreach. I guess it was necessary in the past,
8521 but I think it's a no-op now.
8523 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8525 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8526 ``cat <<_ACEOF'' commands to one.
8527 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8528 * lib/autoconf/status.m4: On various places, use expr instead of
8529 ``echo|sed.''
8530 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8531 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8532 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8533 a range.
8534 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8535 the wrong patterns between ``case'' and ``esac.'' The previous
8536 code had false positives.

8540 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8541 as on 2005-05-02.
8542 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8543 Mention LIBOBJDIR.

8604 * doc/autoconf.texi (Autoconf Language): Be more precise about
8605 quoting rules. Problems noted by Stepan Kasal.
8606 Also, throughout this document, be more careful about white space.
8607 "blank", "white space", and "space" all have different meanings
8608 and we should be careful to say what we mean.
8610 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8612 Fix C++ related problems reported by Werner Lemberg.
8613 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

8645 not newline.
8647 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8648 by AC_DEFINE; it was a mistake.
8649 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.

8659 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8660 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8661 comment and reduce m4_default([foo], []) to [foo].
8662 (m4_strip): Update the explanation.
8664 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8666 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8667 Remove core.conftest.* too; it's generated by Tru64 5.1.
8668 Problem reported by Jennis Pruett.
8669 * lib/autoconf/functions.m4
8670 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8671 Don't bother to remove core files; AC_RUN_IFELSE should do that
8672 for you.
8674 2005-04-19 Stepan Kasal <kasal@ucw.cz>

8722 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8724 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8726 * NEWS: The configure command now warns you if you attempt to use
8727 a directory whose name contains a special character like space,
8728 newline, or "\".
8729 * doc/autoconf.texi (Installation Directory Variables): Allow
8730 "," in file names. Do not use \@; it's not a portable regexp.

8744 ac_pwd, and quote srcdir.
8745 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8747 * doc/autoconf.texi: Fix some systematic formatting problems.
8748 ".)" needs a following @: if not at the end of a sentence, and
8749 similarly for "!)". "etc." should be preceded by a comma.
8750 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8752 2005-03-22 Bruno Haible <bruno@clisp.org>
8754 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8755 argument is often called 'build-aux'.

8762 `AC_CONFIG_FILES'.
8764 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8766 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8767 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8768 from a Common Lisp's `cl'.
8769 (AC_PROG_CXX): Behave according to the documentation: don't
8770 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8771 make the variable CCC precious; use `cl.exe', not `cl'.
8773 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8774 Alexandre Duret-Lutz <adl@gnu.org>
8776 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8777 /dev/null, as "configure" shouldn't read stdin, and this insulates
8778 us from problems (e.g., when testing for "cl"). Also, do this
8779 redirection before invoking "hostname" or "uname", and keep the
8780 original input stream available via...
8781 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8782 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8783 bother with "</dev/null" since it's now done at the top of
8784 'configure'.
8785 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8786 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8787 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8788 * doc/autoconf.texi (File Descriptor Macros): New section.
8789 (Printing Messages): Mention it.
8790 * tests/base.at (Input/Output): New test.
8792 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8794 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8795 newline if neither \c nor -n work, as that would output two
8796 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8798 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8800 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8801 This causes that any required macros inside will get before the if.
8802 * doc/autoconf.texi (autom4te.cache): A typo.
8804 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8806 Undo previous change, except keep the change to
8807 lib/autoconf/programs.m4 that replaced grep with shell
8808 pattern-matching. This is because net-snmp configure reads stdin.
8809 Reported by Noah Misch.
8811 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8813 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8814 from /dev/null, as "configure" shouldn't read stdin, and this
8815 insulates us from problems (e.g., when testing for "cl").
8816 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8817 before invoking "hostname" or "uname".
8818 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8819 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8820 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8821 "</dev/null" since it's now done at the top of 'configure'.
8822 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8823 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8824 Also, replace grep with shell pattern-matching, to save a process.
8826 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8828 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8829 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8830 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8831 compiler.
8833 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8835 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8836 grep -q isn't portable. Improve grep -s explanation.
8837 Problem reported by Dan Manthey.
8839 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8841 * doc/autoconf.texi (Special Shell Variables): Clarify
8842 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8844 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8846 * doc/autoconf.texi: Use @acronym for DJGPP.
8847 Fix some @code's that should have been @env's, and vice versa.
8848 Sort environment variable names.
8849 Mention that shells no longer inherit IFS.
8850 Don't recommend PATH_SEPARATOR=';' so strongly.
8851 Mention that $RANDOM might expand to the empty string.
8852 "symlink" and "soft link" -> "symbolic link".
8853 Improve mktemp description (reported by Bruno Haible).
8855 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8857 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8858 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8859 Likewise.
8860 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8861 Likewise.
8863 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8865 * NEWS: Mention AT_COPYRIGHT.
8867 * tests/local.at (AT_CMP): Use diff directly on input files rather
8868 than copying them.
8870 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8871 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8873 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8874 and Paul Eggert <eggert@cs.ucla.edu>
8876 * tests/autotest.at (Empty test suite): New test.
8877 * tests/torture.at (Substitute and define special characters)
8878 (Substitute a 2000-byte string, Define to a 2000-byte string)
8879 (Substitute a newline, Define a newline): New tests.
8881 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8883 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8884 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8885 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8886 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8887 (Standard regular expressions): New test.
8888 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8889 excess test name quoting.
8890 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8891 CPPFLAGS to `configure' instead of setting it in `configure'.
8893 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8894 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8895 on some platforms.
8897 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8898 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8900 * tests/local.at (AT_CMP): New macro.
8901 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8902 (AC_SAVE_STATE): Move environment grep...
8903 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8904 (AT_CONFIG_CMP): New macro.
8905 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8906 * tests/c.at (Extensions): Do not exit early.
8907 * tests/atlocal.in: Inherit $GREP.
8909 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8910 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8912 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8913 (AC_COPYRIGHT): Factor header comment portion out and move into...

8924 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8926 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8928 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8929 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8931 Try not to generated lines of unlimited length, as POSIX places a
8932 2047-byte limit on line length of portable text files.
8933 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8934 Use newline as a separator, not space.
8935 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8936 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8937 space.
8939 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8941 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8942 as_func_*. Add test to check whether positional parameters
8943 are restored after function return.
8945 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8947 * doc/autoconf.texi (Special Shell Variables): Mention _,
8948 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8949 if they contain a lower-case letter. The DUALCASE problem was
8950 reported by Ralf Wildenhues.
8952 * bin/autoconf.as: Don't exit with status 0 after write failure
8953 with --help or --version.
8954 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
8955 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
8957 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8959 * doc/autoconf.texi (Limitations of Usual Tools):
8960 Unicos 9 sed limitations.
8961 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
8962 to get the option-enhanced interface on older Crays. Try ftn for
8963 Fortran 95 (newer Crays).
8965 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8967 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8968 care to echo the commands, so the user knows what's going on.
8969 Modified from a suggestion by Stepan Kasal.
8971 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
8972 with a cross reference. Derived from a suggestion by Bruce Korb.
8974 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
8976 * doc/autoconf.texi (config.status Invocation): Warn about
8977 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
8978 * doc/install.texi (Defining Variables): Likewise.
8979 Based on a proposed patch by Ralf Wildenhues.
8981 * man/Makefile.am (.x.1): Make sure the required generated files
8982 are up to date. Problem and original solution proposed by Stepan Kasal.
8983 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
8984 implicit-man-prerequisites): New rules, used by the above.
8986 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
8987 * config/config.guess, config/config.sub, config/install-sh: Likewise.
8988 * config/missing, config/texinfo.tex: Likewise.
8990 2005-01-29 Stepan Kasal <kasal@ucw.cz>
8992 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8993 Update the long comment explaining it.
8995 m4_require no longer writes an ``is required by'' line to the
8996 execution stack. It contains only one bit of non-redundant
8997 information: that the macro was required, not called. And even
8998 this bit is useless in most situations: have you ever met a macro
8999 which both calls and requires the same macro?
9001 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9002 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9003 macro.
9004 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9005 (m4_expansion_stack_pop): Remove the misplaced comment.
9006 (m4_require): Don't put the ``is required by'' line to the
9007 execution stack; slightly improve the out-of-a-defun error message.
9008 (_m4_divert_grow): New macro, counter for the temporary diversions.
9009 (_m4_require_call): Use it.
9010 * tests/m4sugar.at (m4_require): Expect output without the
9011 ``is required by'' messages.
9013 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9015 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
9016 rather than x for expr.
9018 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
9019 this is safe.
9020 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
9021 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9022 * lib/autotest/general.m4 (AT_INIT): Likewise.

9024 * tests/mktests.sh: Likewise.
9026 2005-01-27 Akim Demaille <akim@epita.fr>
9028 Have autoheader honor --force.
9030 * doc/make-stds.texi, doc/standards.texi: Update from masters.
9031 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
9032 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
9033 from masters, so that FileUtils.pm's update_file provide --force
9034 support.
9035 * bin/autoheader.in: Pass $force to update_file so that
9036 config.h.in is always recreated when --force.
9038 2005-01-24 Stepan Kasal <kasal@ucw.cz>
9040 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
9042 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9044 * doc/autoconf.texi (Limitations of Builtins): Clarify that
9045 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
9047 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
9049 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
9050 Warn about newline stripping in `` and $(). Update Solaris
9051 version to 9.
9052 (Limitations of Builtins): Use expr "X...", not expr "x...", as
9053 X insulates us from future changes to Posix.
9054 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
9055 stripping.
9057 2005-01-19 Stepan Kasal <kasal@ucw.cz>
9059 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
9060 you cannot use AC_DEFINE to define macros containing `[' or `]'.
9062 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
9064 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
9065 in Solaris 8 join. Problem reported by Tomohiro Suzuki on
9066 bug-tar mailing list.

9072 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9074 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
9075 ulongval to be static, to avoid unwanted GCC warning. Problem
9076 reported by Michael Jennings via Daniel Reed; see
9077 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
9079 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
9081 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
9082 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
9083 datadir, infodir, and mandir. Adjust argument parsing code.
9084 (_AC_INIT_HELP): Update help text.
9085 * doc/autoconf.texi (Installation Directory Variables): Document
9086 new variables.
9088 2005-01-04 Noah Misch <noah@cs.caltech.edu>
9090 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
9091 not seem to work, assume it does set $(MAKE).
9092 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
9094 2005-01-03 Stepan Kasal <kasal@ucw.cz>
9096 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
9098 2005-01-03 Stepan Kasal <kasal@ucw.cz>
9100 A cleanup of the diversion support in m4sugar.
9102 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
9103 (_m4_divert_n_stack): New macro; the expansion is
9104 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
9105 otherwise.
9106 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
9107 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
9108 stored in _m4_divert_diversion or _m4_divert_dump.
9109 (m4_divert_pop): When the parameter is given, compare the symbolic
9110 name with the last diversion pushed on the stack. Previously, the
9111 current diversion was compared with the numeric value of the
9112 diversion given as the parameter.
9113 (m4_require): If the macro hasn't been expanded yet, call ...
9114 (_m4_require_call): this new macro.
9116 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9118 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

9145 2004-12-30 Noah Misch <noah@cs.caltech.edu>
9147 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
9148 signals that the package uses Automake; a `Makefile.am' is typical but
9149 not essential. Reported by Magnus Therning.
9150 * tests/torture.at (autoreconf.): New banner.
9151 (autoreconf and non-AC configure): Rename to `Non-Autoconf
9152 AC_CONFIG_SUBDIRS'.

9168 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
9169 If the variable to set is already set, set ac_cv_path_$1
9170 to the preset value so caller can assume ac_cv_path_$1
9171 is available. (trivial change)
9173 2004-12-27 Noah Misch <noah@cs.caltech.edu>
9175 * BUGS (Minor Problems): Warn about makefile limitations.

9187 problems with SunOS ksh and backslash escaping, Bourne shells and
9188 closing brackets (both within character classes). Bug reported
9189 against Libtool by Alexander Kurz <alexander.kurz@qsc.de>.
9190 <read>: New entry. Mention non-availability of -r.
9192 2004-12-21 Akim Demaille <akim@epita.fr>
9194 * lib/autotest/general.m4 (AT_LINE): Don't add srcdir here, to
9195 avoid cluttering displayed messages. Rather, prepend srcdir where
9196 AT_LINE is used for log files.
9198 2004-12-21 Stepan Kasal <kasal@ucw.cz>
9200 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
9201 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

9421 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

9540 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

9667 * doc/autoconf.texi (Shellology): Note that set -o posix is
9668 useful for pkdsh, too.
9670 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9672 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9673 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9674 Don't fail if ENV or BASH_ENV is readonly.
9675 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9676 etc. are read only. Problem reported by Ludovic Courtes.
9678 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9680 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9681 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9682 (trivial change)
9684 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9686 * doc/autoconf.texi (File System Conventions): Warn about
9687 names like "aux". Problem reported by Eric Blake.
9689 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9690 by zero instead of array size, so that we can use any arithmetic
9691 constant expression (instead of requiring an integer constant
9692 expression). This allows us to test expressions like DBL_MAX <
9693 LDBL_MAX, which didn't conform to the C standard using the old
9694 method.
9695 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9696 now that we can do floating-point tests at compile time.
9698 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9700 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9701 and LDBL_EPSILON, as the resulting expression isn't an
9702 integer constant expression and violates the C standard.
9703 Problem reported by Nelson H. F. Beebe. Also, check
9704 for "L" suffix, and check that long double doesn't have
9705 worse range or precision than double, that mixed-mode
9706 arithmetic doesn't generate a diagnostic, that double
9707 constants fit in long double.
9709 2004-06-03 Kevin Ryde <user42@zip.com.au>
9711 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9712 malloc(0) and realloc(NULL,size).
9714 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9715 Bob Proulx.
9717 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9719 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9720 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9721 by Jim Meyering.
9723 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9725 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9726 can be rewritten using if-then-else. Suggested by Bruno Haible.
9728 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9730 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9731 Problem reported by Stepan Kasal.
9733 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9735 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9736 change). Patch reported by Ralf Wildenhues in
9737 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9739 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9740 function F exists if the compiler and linker let you compile an
9741 expression like (F != 0). Recent versions of GCC optimize away
9742 the reference to F in that case, since every function address must
9743 be nonzero, so the link succeeds even if F does not exist.
9744 Problem reported by Manu in
9745 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9747 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9748 "Unix". Many uses changed.
9749 (Limitations of Builtins): Explain better why the ! command isn't
9750 portable.
9752 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9754 * lib/autom4te.in (Automake-preselections): Preselect
9755 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9757 2004-05-19 Kevin Ryde <user42@zip.com.au>
9759 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9760 referencing AC_FUNC_STRERROR_R.
9762 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9763 note pessimistic assumption when cross compiling.
9765 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9767 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9768 (until 2004) invoked subcommands with sh -e, contra POSIX.
9769 Reported by Kevin Ryde.
9771 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9773 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9774 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9775 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9776 `test -f " /usr/bin/grep"', which _always_ failed.
9777 (AC_PROG_SED): Ditto bogus PATH fix.
9778 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9779 requires that grep correctly supports _multiple_ `-e' options, rather
9780 than stating only that grep should accept `-e'.
9782 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9784 Port to C99, which requires that 'exit' be declared.
9786 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9787 to ensure that stdlib.h is included.
9788 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9789 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9790 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9791 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9792 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9793 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9794 when using 'exit' in a test; C99 requires that 'exit' be declared.
9796 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9798 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9799 now prefers 'grep' implementations that accept -e.
9800 (Limitations of Usual Tools): Describe problems of traditional
9801 egrep and fgrep with long input lines, and of traditional grep
9802 with -e.
9803 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9804 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9805 All callers changed. Append /usr/xpg4/bin to the PATH, for
9806 Solaris.
9807 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9808 the user with complaints about multiple -e options.
9809 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9810 Define it with AC_PROG_GREP.
9811 * configure.ac (AC_PROG_GREP): Add.
9812 * lib/freeze.mk (GREP): New macro.
9814 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9816 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9817 a possible candidate only after all others fail, rather than
9818 consulting it first. This improves backward compatibility by
9819 better reflecting the way shell selection occurred in previous
9820 versions of Autoconf, and should help to avoid triggering latent
9821 problems in other packages, such as the one in Automake where zsh
9822 is not handled robustly:
9823 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9824 Although it is not Autoconf's responsibility to work around
9825 problems in Automake, it nevertheless makes sense to avoid
9826 introducing unnecessary incompatibilites.
9828 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9829 Gary V. Vaughan <gary@gnu.org>
9831 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9832 how deeply nested we are when a suitable tool is found, set the
9833 ac_path_TOOL_found flag.
9834 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9835 nested we are in this macro. Break out of all 3 nested loops if
9836 ac_path_TOOL_found is set.
9838 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9840 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9841 of the _AS_PATH_WALK loop too if GNU flavor is found.
9843 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9845 * doc/autoconf.texi (Limitations of Make): Update documentation
9846 for `$<'. New entry `Long lines', based on a report from Simon
9847 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9848 paragraph about DJGPP, based on a mail from Richard Dawe.
9850 2004-04-20 Paul Eggert <eggert@twinsun.com>
9852 * tests/c.at (C keywords): Don't assume that GCC supports
9853 "restrict" and "inline", as sufficiently-old GCC versions do not
9854 (also, GCC configured to be in pedantic C89 mode does not).
9855 Problem reported by Sumit Pandya in:
9856 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9858 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9859 consider -g to work if it generates warnings when plain compiles
9860 don't. Problem reported by Braden McDaniel in:
9861 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9863 * doc/autoconf.texi (Slashes): New section, to document a problem
9864 reported by Jim Meyering in:
9865 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9867 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9868 linker output files before linking, to work around IRIX 6 linker bug.
9869 Problem reported by Rainer Orth in:
9870 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9872 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9874 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9875 best tool so far counter rely on the tool path variable name to
9876 avoid checks for one tool being affected by the results of running
9877 the length check on a previous tool.
9879 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9880 match expression argument, as different greps have different
9881 regular expression flavours.
9882 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9883 literals.
9884 (AC_PROG_EGREP): Pass 'EGREP$'.
9885 (AC_PROG_GREP): Pass 'GREP$'.
9887 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9889 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9890 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9892 2004-03-29 Paul Eggert <eggert@twinsun.com>
9894 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9895 Types, Specific Compiler Characteristics, System Services,
9896 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9897 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9898 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9899 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9900 Likewise.
9901 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9902 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9903 AC_TYPE_OFF_T): Likewise.
9904 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9905 Likewise.
9907 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9908 pacify libtool 1.5.2. Fix quoting problems in sed command.
9910 2004-03-28 Paul Eggert <eggert@twinsun.com>
9912 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9913 now defines HAVE_DECL_TZNAME if it is declared, when
9914 HAVE_STRUCT_TM_TM_ZONE is not defined.
9915 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9916 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9917 for HAVE_TZNAME.
9919 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9921 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9922 superfluous backslashing of quotes (") in sed expressions;
9923 thanks to Paul Eggert.
9925 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9927 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9928 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9929 H. F. Beebe for the bug report.
9931 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9933 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9934 quoted -cmdline argument in Portland Group compiler (bug
9935 reported by Jeffrey J. Barteet).
9937 2004-03-25 Kevin Ryde <user42@zip.com.au>
9939 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9940 (Run Time): ... here, where it's now mentioned.
9942 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
9944 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9945 inherits from language Autoconf-without-aclocal-m4.
9946 (Customizing autom4te): Adjust example; the cache must now be
9947 disabled for language Autoconf-without-aclocal-m4.
9949 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
9950 Nathanael Nerode <neroden@twcny.rr.com>

9960 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
9961 AC_CHECK_TOOLS.
9962 (Specifying Names): Document the reason for these future
9963 behavioral changes.
9964 * tests/mktests.sh: Do not generate tests for the
9965 new macros.
9966 * NEWS: Document these changes.
9968 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9969 they make TeX hang up.
9971 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9973 * NEWS: New macro AC_CHECK_ALIGNOF.
9974 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9975 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9976 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9977 vowel.
9978 (AC_CHECK_ALIGNOF): New macro.
9979 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9980 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9981 those for sizeof.
9983 2004-03-03 Paul Eggert <eggert@twinsun.com>
9985 * bin/Makefile.am (edit): Don't use $< in a context where
9986 POSIX doesn't require support for it. Use $@.in instead.
9987 Problem reported by Anthony N. Frasso in
9988 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9989 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9991 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9993 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9994 from the next generation of Libtool.
9995 * lib/autom4te.in (Autoreconf-preselections): Ditto.

10010 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10011 (MAINTAINERCLEANFILES): Split into pieces,
10012 one per related section. Add $(srcdir)/wrapper.in.
10014 2004-02-09 Paul Eggert <eggert@twinsun.com>

10017 AC_SUBST provides no portable way to escape literal newlines.
10019 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10020 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10021 Darwin uses -lcrt2.o and there's little point to cataloging all
10022 the system variants. Partial fix reported by Andreas Waechter in:
10023 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
10024 for bug reported by Nelson H. F. Beebe in:

10034 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
10036 * bin/autoupdate.in: Define __file__ so that warnings
10037 refer to the correct file.
10038 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
10039 the behavior of the third argument.
10040 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
10041 correctly the behavior of the third argument. Document
10042 what the three macros that AU_DEFUN defines do. Fix
10043 warning message when the third argument includes $0
10044 (reported by Alexandre Duret-Lutz).
10046 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10047 Eric Sunshine <sunshine@sunshineco.com>
10048 Paul Eggert <eggert@twinsun.com>
10050 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
10051 (AS_INIT): Output shell initialization there. Removed optional
10052 parameter. Expand _AS_SHELL_FN_SPY.
10053 (AS_INIT_WITH_SHELL_FN): Removed.
10054 (_AS_SHELL_FN_SPY): New macro.
10055 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
10056 macros.
10057 (AS_SHELL_SANITIZE): Remove loop to find better shell
10058 and documentation for the parameter.
10059 (_AS_DETECT_BETTER_SHELL): Move it here.

10065 trigger the bash bug anymore.
10066 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10067 use AS_INIT_WITH_SHELL_FN.
10068 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10070 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10072 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

10074 is broken.
10075 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
10076 (AU_DEFUN): Honor the third parameter, create autoupdate
10077 macros with AU_DEFINE.

10096 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
10097 copyright years.
10098 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

10100 the 2003-05-22 change, which removed the older years from the list.
10101 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10106 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
10107 grep or ggrep program in PATH that accepts as long lines as
10108 possible.
10109 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
10110 AC_PROG_GREP.
10111 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
10112 egrep and fgrep respectively if $GREP -E/-F don't work.
10113 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10114 _AC_PROG_GREP, and AC_PROG_SED.
10115 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10116 longest input length accepted by a command.
10117 (AC_PROG_SED): Use it.
10118 * doc/autoconf.texi (Particular Programs): Document the changes.
10119 * NEWS: Updated.
10121 2004-01-27 Paul Eggert <eggert@twinsun.com>
10123 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
10124 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10125 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
10126 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
10128 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
10129 bin/autoconf.in, config/Makefile.in, config/config.guess,
10130 config/config.sub, config/install-sh, config/mdate-sh,
10131 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
10132 lib/Makefile.in, lib/Autom4te/Makefile.in,
10133 lib/autoconf/Makefile.in, lib/autoscan/Makefile.in,
10134 lib/autotest/Makefile.in, lib/emacs/Makefile.in,
10135 lib/m4sugar/Makefile.in, man/Makefile.in, man/autoconf.1,
10136 man/autoheader.1, man/autom4te.1, man/autoreconf.1,
10137 man/autoscan.1, man/autoupdate.1, man/config.guess.1,

10141 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
10142 tests/actypes.at: Regenerate and/or sync with original
10143 sources.
10145 2004-01-26 Paul Eggert <eggert@twinsun.com>
10147 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10148 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10149 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10150 not <inttypes.h>. Problem reported by Tim Mooney in
10151 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10152 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10153 Likewise.
10155 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10156 otherwise "make check" fails because it forbids cmp (I guess
10157 because cmp treats files as binary on DOS-like systems).
10159 * tests/mktests.sh: Update copyright date to 2004, since some tests
10160 have changed in 2004.
10162 2004-01-23 Gary V. Vaughan <gary@gnu.org>
10164 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
10165 non-truncating sed or gsed program in PATH.
10166 * tests/acprograms.at: Add it.
10167 * doc/autoconf.texi (Particular Programs): Document it.
10168 * NEWS: Updated.
10170 2004-01-15 Paul Eggert <eggert@twinsun.com>
10172 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10173 -std1 disables some useful extensions on Tru64. Problem reported
10174 by N. Lichtmaier in
10175 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10177 2004-01-14 Paul Eggert <eggert@twinsun.com>
10179 * doc/autoconf.texi (Programming in M4sh): Document that
10180 AS_MKDIR_P succeeds if the destination is a symbolic link
10181 to an existing directory.
10182 (Limitations of Usual Tools): Note that mkdir -p might not
10183 succeed on symlinks to directories.
10185 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10187 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10188 * bin/autoheader.in: Grammar fix in message.
10189 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10190 Test for dir before calling mkdir -p. (trivial changes)
10192 2004-01-13 Eric Blake <ebb9@byu.net>
10194 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10195 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10197 2004-01-10 Jim Meyering <jim@meyering.net>
10199 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10201 2004-01-09 Paul Eggert <eggert@twinsun.com>
10203 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10204 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10205 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10206 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10207 AC_COMPILE_IFELSE, since we now assume our caller invokes
10208 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10209 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10210 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10211 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10213 2004-01-07 Paul Eggert <eggert@twinsun.com>
10215 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10216 `"'...'"`, as it's confusing (and I suspect it may not work on
10217 some platforms). The code was incorrect anyway, as it assumed
10218 that \$ evaluated to itself in that context. Reported by
10219 Alexandre Duret-Lutz.
10221 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10223 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10224 and _LT_AC_TAGCONFIG.
10226 2004-01-06 Paul Eggert <eggert@twinsun.com>
10228 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10229 example, and add more examples. Reported by Eric Sunshine.
10231 2004-01-05 Paul Eggert <eggert@twinsun.com>
10233 * doc/autoconf.texi (Limitations of Usual Tools):
10234 Remove warning against "rm -fr" introduced yesterday; it
10235 was a false alarm.
10237 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
10238 autoscan, autoupdate, ifnames): Don't use chmod -w.
10239 * lib/Makefile.am (autom4te.cfg): Likewise.
10240 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
10241 "chmod -w".
10243 2004-01-04 Paul Eggert <eggert@twinsun.com>
10244 Paolo Bonzini <bonzini@gnu.org>
10246 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
10247 by doing lineno substitution only on lines containing "$LINENO".
10249 2004-01-04 Paul Eggert <eggert@twinsun.com>
10251 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10252 Use "rm -f" to remove conftest.sed, not plain "rm".
10253 Bug reported by David Relson in
10254 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10256 * Makefile.am (autom4te-update):
10257 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10258 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10259 * doc/autoconf.texi (Guidelines): Likewise.
10260 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
10261 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
10262 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10263 * lib/autotest/general.m4 (AT_INIT): Likewise.
10264 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
10265 * tests/Makefile.am (clean-local): Likewise.
10266 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
10267 srcdir): Likewise.
10268 * doc/autoconf.texi (Limitations of Usual Tools):
10269 Warn against "rm -fr".
10271 2004-01-03 Paul Eggert <eggert@twinsun.com>
10273 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10274 -c -o might not work. From a suggestion by Kevin Ryde.
10275 (C Compiler, Generating Sources, Limitations
10276 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10277 Don't put '-o' after non-options, as POSIX doesn't allow this.
10278 Mention that cc's name might be gcc or c89 or whatever.
10280 2004-01-04 Kevin Ryde <user42@zip.com.au>
10282 * doc/autoconf.texi: Add various further index entries.
10284 2003-12-29 Paul Eggert <eggert@twinsun.com>
10286 * bin/autoreconf.in (autoreconf_current_directory):
10287 Fix typo: mkdir without umask arg.
10289 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10291 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10292 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10293 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10294 explanation clearer.
10296 2003-12-24 Andreas Schwab <schwab@suse.de>
10298 * doc/autoconf.texi (Default Includes): Fix misspelling of
10299 AC_INCLUDES_DEFAULT.
10301 2003-12-03 Paolo Bonzini <bonzini@gnu.org>

10304 * configure: Regenerate.
10305 * tests/atlocal.in: Store the result here.
10306 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
10307 tools.at, looking in atlocal's ac_cv_sh_n_works instead
10308 of explicitly testing.
10309 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10310 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10311 * tests/tools.at (Syntax of the shell scripts): Simplify
10312 using AT_CHECK_SHELL_SYNTAX.
10313 (Syntax of the Perl scripts): Remove definition of
10314 AT_CHECK_PERL_SYNTAX.
10316 2003-12-03 Paolo Bonzini <bonzini@gnu.org>

10326 Extracted from AS_SHELL_SANITIZE.
10327 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
10328 macros.
10329 (AS_SHELL_SANITIZE): Move reinvocation code from
10330 _AS_LINENO_WORKS, use it to find out if shell
10331 functions work.
10332 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

10346 (&sizes): New.
10347 Use them.

10349 them on the fly.
10351 2003-11-24 Akim Demaille <akim@epita.fr>
10353 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

10376 the transition better.
10378 2003-11-24 Paolo Bonzini <bonzini@gnu.org>
10380 * doc/autoconf.texi (Obsoleting Macros): Don't document the third
10381 parameter of AU_DEFUN.
10382 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
10383 (AU_DEFUN): Remove the third parameter, it was not used.
10384 Use AC_DEFUN directly, not AU_DEFINE.
10385 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
10386 the expanded body, consistently with other macros such as AC_USG.
10388 2003-11-17 Paul Eggert <eggert@twinsun.com>
10390 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

10392 patch 3 reported by Eric Sunshine.
10394 2003-11-15 Kevin Ryde <user42@zip.com.au>
10396 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10397 than $target since the latter is not usual, add guidelines on when to
10398 use or not use the system type.
10400 2003-11-12 Derek Price <derek@ximbiot.com>
10402 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10422 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
10423 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

10450 computing the absolute path to d1 in the source hierarchy: it may
10451 not exist at all. So don't cd into it.
10452 From Alexandre Duret-Lutz.
10453 http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00205.html

10516 same object file in $LIBOBJS.
10517 Reported by Alexandre Duret-Lutz & Derek Robert Price.
10518 * doc/autoconf.texi (Generic Functions): Adjust.
10520 2003-10-20 Paul Eggert <eggert@twinsun.com>

10555 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
10557 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
10558 cross test.
10560 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
10562 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
10563 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10565 2003-10-10 Andreas Schwab <schwab@suse.de>
10567 * bin/autoheader.in: Avoid empty first line in --version and
10568 --help output.
10569 * bin/ifnames.in: Likewise.
10571 2003-10-09 Paul Eggert <eggert@twinsun.com>
10573 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
10574 Issue a more-informative diagnostic.
10575 Problems reported by Eric Sunshine.
10577 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10579 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10580 -mGLOB_options_string stuff for Intel ifc, which can cause
10581 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10582 pattern-matching instead of grep.
10584 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10586 * doc/autoconf.texi: Document new FC Fortran macros.
10588 2003-10-08 Gary V. Vaughan <gary@gnu.org>
10590 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
10591 that future autopoint/aclocal/automake/autoreconf will be able
10592 to trace to find where to install local m4 macros.
10593 * doc/autoconf.texi (Input): Document it.
10594 * NEWS: Updated.
10596 2003-10-06 Gary V. Vaughan <gary@gnu.org>
10598 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
10599 -lcrtbegin.o to list of ignored flags and fix underquoting of
10600 -lcrt[01].o.
10602 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10604 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10605 cache variable instead of $G77 to decide whether to include -O2,
10606 since $G77 is specific to Fortran 77.
10608 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10610 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10611 free" flag. Re-order flags tested into rough order of popularity.
10613 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10615 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10616 arguments so that it can be used with syntax identical to
10617 AC_PROG_F77, and so that we can more easily decide to
10618 remove/deprecate the DIALECT optional argument in the future if it
10619 proves troublesome.
10620 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10621 non-freeform-supporting compilers. Document freeform flags.
10623 2003-10-03 Akim Demaille <akim@epita.fr>
10625 * configure.ac: Look for emacs, not macs.
10626 Reported by Eric Sunshine.
10628 2003-10-03 Akim Demaille <akim@epita.fr>
10630 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10631 * bin/autoreconf.in (autoreconf_current_directory): Create the
10632 AUX_DIR if needed, for sake of automake --add-missing etc.
10633 Suggested by Alexandre Duret-Lutz.
10635 2003-10-03 Akim Demaille <akim@epita.fr>
10637 * configure.ac: Quotation and formatting changes.
10638 (EMACS): Don't set it if it is not recent enough to support
10639 autoconf-mode.el.
10640 From Eric Sunshine.
10642 2003-10-02 Akim Demaille <akim@epita.fr>
10644 * bin/ifnames.in (&scan_file): Skip C++ comments.

10654 Version 2.57f.
10656 2003-09-30 Paul Eggert <eggert@twinsun.com>
10658 * lib/Autom4te/XFile.pm: Use Errno.
10659 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
10660 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
10662 2003-09-30 Akim Demaille <akim@epita.fr>
10664 * config/announce-gen (&print_news_deltas): Extracted from...
10665 (&print_changelog_deltas): here.
10666 (&news_file): Rename as...
10667 (@news_file): this.
10669 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10671 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10672 have been created when invoking the compiler.
10673 * tests/fortran.at (GNU Fortran 77): Quote $G77.
10675 2003-09-29 Akim Demaille <akim@epita.fr>
10677 Version 2.57e.
10679 * config/mkinstalldirs: Upgrade.
10681 2003-09-28 Paul Eggert <eggert@twinsun.com>
10683 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
10684 Problem reported by Lars J. Aas in
10685 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10686 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10687 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10688 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10690 2003-09-26 Akim Demaille <akim@epita.fr>
10692 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10693 directory for AC_CONFIG_COMMANDS' first argument exists.
10694 This makes valid the invocation of _AC_SRCPATH that follows.
10695 Reported by Eric Sunshine.
10696 * doc/autoconf.texi (Configuration Commands): Adjust.
10698 2003-09-26 Akim Demaille <akim@epita.fr>
10700 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10701 Reported by Ralf Corsepius.
10703 2003-09-26 Akim Demaille <akim@epita.fr>
10705 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10706 arguments.
10707 Actually, use AU_ALIAS.
10708 From Bruno Haible.
10710 2003-09-26 Paul Eggert <eggert@twinsun.com>
10712 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
10713 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
10714 Problem reported by Eric Sunshine in:
10715 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
10717 2003-09-26 Akim Demaille <akim@epita.fr>
10719 The test suite are sometimes assigning timings incorrectly.
10720 Reported by Henk Krus.
10721 Diagnosed by Nicolas Joly.
10723 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10724 AT_help_all.
10725 Instead of making AT_help a sequence of assignments to grow
10726 $at_help_all, just make AT_help_all be the growing contents of
10727 $at_help_all, and make a single assignment in...
10728 (AT_INIT): here.
10729 (at_times_skip): Flip the meaning and rename as...
10730 (at_times_p): this.
10731 (AT_INIT): When summarizing the test that ran, remove
10732 $at_times_file after use, and check it is present before trying to
10733 use it.
10735 2003-09-25 Akim Demaille <akim@epita.fr>
10737 Version 2.57d.
10739 * bin/Makefile.am (edit): Handle '@configure_input@'.
10740 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10741 (ifnames): chmod -w.
10742 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10743 executables, not bin/ executables! Otherwise all the magic needed
10744 to find non installed files is turned off. This caused a failure
10745 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10746 as found in its environment (sent by tests/autoreconf): pointing
10747 to bin/autom4te that could not find its files.
10748 * tests/mktests.sh: Force the replacement of generated files, for
10749 the sake of "mv" program that are interactive when overwriting a
10750 -w file.
10751 * config/install-sh: Upgrade from CVS Automake.
10753 2003-09-23 Paul Eggert <eggert@twinsun.com>

10756 versus test -L issues.
10758 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10759 Paul Eggert <eggert@twinsun.com>
10761 Trivial change to support GCC's configuration procedure.
10762 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10763 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10764 about inconsistency if the preprocessor is set to give errors for
10765 any warning.
10766 * doc/autoconf.texi (C Compiler Characteristics): Document this.
10768 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
10770 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
10771 and XFile.pm from Automake.
10772 * lib/Autom4te/XFile.pm: Update from Automake.
10774 2003-09-12 Akim Demaille <akim@epita.fr>

10781 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
10782 from masters.
10784 2003-09-12 Akim Demaille <akim@epita.fr>
10786 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
10787 not asm/types.h.
10789 2003-09-11 Akim Demaille <akim@epita.fr>
10791 * doc/autoconf.texi (Header Portability): linux/random.h.
10792 From Peter Hendrickson.
10794 2003-09-10 Akim Demaille <akim@epita.fr>
10796 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10797 willing to edit the output files.
10799 2003-09-10 Akim Demaille <akim@epita.fr>
10801 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10802 and AC_FC_FREEFORM.
10803 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10804 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10806 2003-09-09 Akim Demaille <akim@epita.fr>
10808 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
10809 Reported by Gary Vaughan.
10810 * bin/autom4te.in (handle_m4): Likewise.
10812 2003-09-09 Akim Demaille <akim@epita.fr>
10814 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
10815 trailing files.
10817 2003-09-07 Paul Eggert <eggert@twinsun.com>
10819 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10820 Improve the accuracy of the wording about obsolescence.
10821 From a suggestion by Ian Lance Taylor in
10822 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10824 2003-09-05 Paul Eggert <eggert@twinsun.com>
10826 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10827 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10829 2003-09-04 Akim Demaille <akim@epita.fr>
10831 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10832 AC_FUNC_WAIT3.
10834 2003-09-04 Akim Demaille <akim@epita.fr>
10836 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10837 (freeze): When exiting, use $exit_code.
10838 * lib/autoconf/fortran.m4: Comment changes.
10840 2003-09-04 Akim Demaille <akim@epita.fr>
10842 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10844 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10846 Add support for newer Fortran dialects. The F77 interface is
10847 unchanged, and continues to support Fortran 77. New FC macros
10848 correspond to all the old F77 macros, with output variables FC,
10849 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10850 available dialect, but older dialects can be specified. There are
10851 new macros AC_FC_SRCEXT to set the source extension, and
10852 AC_FC_FREEFORM to accept free-form source files.
10854 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10855 New macros.
10856 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10857 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10858 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
10859 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

10867 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
10868 AC_FC_SRCEXT, AC_FC_FREEFORM):
10869 New macros.
10870 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
10871 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10872 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10873 Rewrite in terms of the above.
10874 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10875 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
10876 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
10877 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10879 2003-09-02 Paul Eggert <eggert@twinsun.com>
10881 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10882 Document problems with timestamp resolution that 'make', 'cp -p', and
10883 'touch -r' have.
10885 2003-08-27 Akim Demaille <akim@epita.fr>
10887 * tests/m4sugar.at (cross_warning): Make sure to enable the
10888 output, so that we can track spurious m4sugar output.
10889 * tests/local.at: Require 2.57.
10890 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10891 are defaulted by AT_CHECK anyway.
10892 Use AT_CHECK_AUTOM4TE.
10893 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10894 missing dnl.
10896 2003-08-27 Akim Demaille <akim@epita.fr>
10898 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10899 when -Wobsolete is set.
10900 Set it on by default.
10901 Suggested by Klee Dienes.
10903 2003-08-27 Akim Demaille <akim@epita.fr>
10905 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
10906 documentation.
10907 From Guido Draheim.
10909 2003-08-26 Akim Demaille <akim@epita.fr>

10912 after AC_OUTPUT.
10914 2003-08-25 Akim Demaille <akim@epita.fr>
10916 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
10917 CVS Bison.
10919 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>

10938 * Makefile.maint (local-check): Rename as...
10939 (local-checks-available): this.
10940 (local-check): New.
10942 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
10943 * configure.ac: Require Automake 1.7.6.
10945 2003-08-22 Akim Demaille <akim@epita.fr>
10947 Output stack traces in warnings.
10949 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10950 Replace the former...
10951 (m4_warn): Pass the call stack to _m4_warn.
10952 * bin/autom4te.in: Adjust to output the call stack.
10953 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10955 2003-08-22 Akim Demaille <akim@epita.fr>
10957 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
10958 * bin/autom4te.in: Adjust.
10960 2003-08-21 Akim Demaille <akim@epita.fr>
10962 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10963 (&verbose): Remove.
10964 (&getopt): Adjust the note and verb channels, depending upon
10965 --verbose.
10966 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10967 * bin/autoupdate.in: Adjust.
10968 Use &verb, not &verbose.
10970 2003-08-21 Akim Demaille <akim@epita.fr>
10972 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10973 &parse_WARNINGS.
10974 ($help): Use Autom4te::ChannelDefs::usage.
10975 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10976 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10978 2003-08-21 Akim Demaille <akim@epita.fr>
10980 First stab at preserving warnings between calls to autom4te,
10981 including when the cache is used.
10983 There are still several issues: (i) there are too many runs of m4
10984 (one for include, one for warnings, and some more), (ii) warnings
10985 spreading on several lines are not handled gracefully, (iii) the
10986 code meant to have the call stack display for errors does not work
10987 (its handling should move from m4 to autom4te).
10989 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10990 Use them.
10991 (@preselect): Add m4_warn.
10992 ($exit_status): Remove, use $exit_code.
10993 ($help): Use Autom4te::ChannelDefs::usage.
10994 (&handle_m4): No longer define the m4_warnings.
10995 At each run, extract and report the warnings.
10996 Always cache the result, including if the exit status is on
10997 failure, since if nothing changes, we should result in the same
10998 failure, hence we can use the cache.
10999 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11000 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11001 Remove.
11002 (m4_warn): Redefine as a do-nothing: it is its invocation that
11003 matters, as warnings are now reported via traces.
11004 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11005 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11006 the latter reveals calls to the former.
11008 Adjust the tests.

11052 * lib/Autom4te/FileUtils.pm: here.
11054 2003-08-20 Akim Demaille <akim@epita.fr>
11056 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
11057 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
11058 from CVS Automake.

11120 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
11121 (AT_CHECK_NOESCAPE): Move core functionality to...
11122 (_AT_CHECK): ...this new macro.
11124 2003-08-07 Derek Price <derek@ximbiot.com>
11126 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
11127 (AT_CHECK_NOESCAPE): ...to this new macro.
11129 2003-07-31 Paul Eggert <eggert@twinsun.com>
11131 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
11132 in Bash 2.01. Problem reported by Brian Gough in
11133 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

11138 -lcrt1.o, for OS X. (trivial change)
11140 2003-07-07 Paul Eggert <eggert@twinsun.com>
11142 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
11143 inside '#ifndef __cplusplus'. Problem reported by
11144 Bob Friesenhahn.
11146 2003-07-06 Bill Clarke <llib@computer.org>
11148 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
11149 'long', not 'int', for benefit of Sun's recent C++ compilers
11150 (trivial change). See:
11151 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
11152 (This really should be 'intptr_t', not 'long', but that would
11153 take more work.)
11155 2003-06-25 Akim Demaille <akim@epita.fr>
11157 * lib/Makefile.am (autom4te.cfg): Make it read only.
11158 Depend on Makefile since it contains substitutions.
11159 From Paolo Bonzini.

11161 This change was made on autom4te.cfg which is generated.

11164 2003-06-25 Akim Demaille <akim@epita.fr>
11166 * doc/autoconf.texi (Header Portability): sys/mount.h.
11167 From Gareth McCaughan.
11169 2003-06-23 Akim Demaille <akim@epita.fr>
11171 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11172 not all of them. This fixes 1. the fact that when testing
11173 Autoconf there are many many config.log, 2. the incorrect use of
11174 top_srcdir to find config.log.
11175 Don't mix the detailed output of failed test with the summary of
11176 failures. Rather, append detailed log afterwards.
11178 2003-06-23 Akim Demaille <akim@epita.fr>
11180 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11181 always run: output config.log on $at_group_log.
11183 2003-06-23 Akim Demaille <akim@epita.fr>
11185 * tests/torture.at (#define header templates): Don't use quotes in
11186 C++ comments as it puzzles Emacs' sh font-lock-mode.
11188 2003-06-23 Akim Demaille <akim@epita.fr>
11190 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
11191 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
11192 * tests/atspecific.m4: Rename as...

11195 * tests/local.at: here.
11196 * tests/Makefile.am: Adjust.
11197 * doc/autoconf.texi (testsuite Scripts): Adjust.

11201 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11202 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11203 ensuring we add -std1 for full-ANSI.
11205 * doc/autoconf.texi (hdrindex): New macro.
11206 Add index entries for portability of various standard header files.
11208 2003-06-20 Akim Demaille <akim@epita.fr>
11210 * configure.ac: Bump to 2.57b.
11212 2003-06-20 Akim Demaille <akim@epita.fr>
11214 Version 2.57a.
11216 2003-06-20 Akim Demaille <akim@epita.fr>
11218 * bin/autom4te.in: Don't rely on $HOME being defined.
11219 Reported by Marc Espie as PR/233.
11221 2003-06-20 Akim Demaille <akim@epita.fr>
11223 * lib/autotest/general.m4: Use at_times_file only if used.
11224 From Nicolas Joly.
11226 2003-06-20 Akim Demaille <akim@epita.fr>
11228 * config/config.guess, config/config.sub, config/elisp-comp,
11229 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
11230 Update from masters.
11232 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
11234 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
11235 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
11236 (TEST_SCRIPT): New diversion.
11237 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
11238 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11239 (AT_INIT): Support for expected failures.
11241 2003-06-02 Akim Demaille <akim@epita.fr>
11243 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
11244 changes.
11245 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
11246 Autoconf nor Automake.
11247 (&contents): New, from Automake.
11248 PODify.
11250 2003-05-28 Paul Eggert <eggert@twinsun.com>
11252 * NEWS, doc/autoconf.texi (Particular Functions),
11253 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11254 is the inverse of localtime.
11256 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11258 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11259 (handle_exec_errors): New function. Work around $! being
11260 altered by WEXITSTATUS.
11261 (xqx, xsystem): Use handle_exec_errors.
11263 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11265 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11266 Do not call `_exit()', simply modify `$?'.
11267 (xsystem): Reset $! before running system, and check it afterward.
11268 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11269 63 for version mismatches.
11271 2003-05-23 Akim Demaille <akim@epita.fr>
11273 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11274 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11275 the middle of a line).
11276 * lib/m4sugar/m4sugar.m4: Likewise.
11277 Remove useless spaces in comments.
11279 2003-05-23 Akim Demaille <akim@epita.fr>
11281 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11282 exit 63, so that we (or Automake's "missing") can tell the
11283 difference with a plain failure.
11284 * doc/autoconf.texi (Notices): Adjust.
11286 2003-05-23 Akim Demaille <akim@epita.fr>
11288 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11289 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11290 White spaces cleanup.
11292 2003-05-22 Jim Meyering <jim@meyering.net>
11293 Paul Eggert <eggert@twinsun.com>
11295 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11296 Remove `#include <stdlib.h>' from the list; we should never
11297 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11298 resulting namespace pollution would cause other tests to fail.
11299 Configure scripts run with some older versions of g++ and HP's
11300 aCC would fail due to such an #include. Problems reported by
11301 Matthew Mueller in <http://bugs.debian.org/120704> and by
11302 Keith Bostic in
11303 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11304 In the test, use the test declaration before including <stdlib.h>,
11305 as that's closer to how it'll be used.
11307 2003-05-23 Akim Demaille <akim@epita.fr>
11309 * doc/autoconf.texi (Header Portability): ucred.h.
11310 From Ian Redfern.
11312 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11314 Overhaul Autotest's logging: generate separate log files
11315 in testsuite.dir/NNN/testsuite.log, and append them to
11316 testsuite.log instead of re-running the test verbosely.
11318 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11319 file descriptor, write 0 to at_status_file instead of setting
11320 at_status=0, initialize some new variables (at_status_file,
11321 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11322 to rerun the tests, instead append the at_group_log to the
11323 at_suite_log when a test fails.
11324 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11325 with the AS_MESSAGE_LOG_FD redirected to stdout.
11326 (AT_CLEANUP): save the output status in $at_status_file
11327 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11328 its original place.
11329 (AT_CHECK): since tests are run with a redirected stdout,
11330 and used to be re-run in verbose mode, turn some $at_verbose
11331 into echo, and don't redirect the output of testing stdout
11332 and stderr.
11334 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11335 the name of the debugging directory and information about
11336 its contents.
11338 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11340 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
11341 parameter.
11343 2003-05-22 Akim Demaille <akim@epita.fr>
11345 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
11346 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
11347 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4
11348 * lib/autoconf/status.m4: Fix and adjust copyright notices.

11363 Whitespace clean up.
11364 Suggested by Jim Meyering.
11366 2003-05-22 Akim Demaille <akim@epita.fr>
11368 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
11369 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
11370 Reported by Jim Meyering.
11372 2003-05-22 Akim Demaille <akim@epita.fr>
11374 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
11375 Add AC_HELP_STRING to the obsolete macros section.
11376 Typos.
11377 Use '@.' for sentences that ended in a capital letter.
11378 From Art Haas.

11396 2003-05-19 Paul Eggert <eggert@twinsun.com>
11398 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:
11399 Remove non-ASCII characters.
11401 2003-05-18 Paolo Bonzini <bonzini@gnu.org>
11403 * tests/semantics.at (AC_SEARCH_LIBS): New test.
11404 * tests/semantics.at (AC_CHECK_HEADERS_OLD,
11405 AC_CHECK_HEADERS_NEW): New tests.
11407 2003-05-17 Akim Demaille <akim@epita.fr>
11409 * lib/autoconf/functions.m4: Use the default includes so that
11410 memcmp be declared before being tested.
11411 Reported by Sander Niemeijer.
11412 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
11413 * doc/autoconf.texi (Default Includes): Document
11414 AC_INCLUDES_DEFAULT.
11416 2003-05-17 Akim Demaille <akim@epita.fr>
11418 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
11419 * doc/autoconf.texi (Obsolete Macros): Adjust.
11420 Reported by Werner LEMBERG and Debian Bug 190886.
11422 2003-05-16 Akim Demaille <akim@epita.fr>
11424 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
11425 user name space clashes.
11426 Reported by Bruno Haible.
11428 2003-05-16 Akim Demaille <akim@epita.fr>
11430 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
11431 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
11432 them uniform, and more robust to Perl special characters.
11433 Reported by Martin Mokrejs.
11435 2003-05-14 Akim Demaille <akim@epita.fr>

11455 2003-05-06 Akim Demaille <akim@epita.fr>
11457 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11458 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11459 by aclocal.m4 is changed it might require the importing of another
11460 m4 extension file, i.e., aclocal must be run.
11462 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11463 (&parse_args): Use --force with aclocal if required and supported.
11464 (&autoreconf_current_directory): Use &run_aclocal.

11471 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
11472 argument instead of a file name, so that the request file remains

11479 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11480 seperator with m4_append_uniq(). It doesn't work.
11481 (AT_CLEANUP): Add `;' to end of at_help_all.
11482 (AT_INIT): Allow --keywords to be specified more than once. When
11483 grepping $at_help_all for keywords, use the field and keyword
11484 seperators to ensure a complete keyword match. Alter at_prev handling
11485 to support the new --keywords behavior.
11487 2003-04-27 Karl Berry <karl@freefriends.org>
11489 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11490 align better with others. I also made some of the individual
11491 entries on one line, for brevity and to make it easier for me to
11492 sort my dir-example file in the Texinfo distribution :).

11533 Use them.
11534 * doc/Makefile.am (CLEANFILES): Adjust.

11563 * tests/torture.at (Configuring subdirectories): Require aclocal
11564 1.4, otherwise the test fails, as it does support configure.ac.
11565 This fixes the "test 40 failed" bug reports.
11567 2003-03-28 Akim Demaille <akim@epita.fr>
11569 * doc/autoconf.texi (C Compiler): `#line' portability.

11575 layout in order to allow scripting around test groups.
11577 2003-03-27 Derek Price <derek@ximbiot.com>
11579 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
11580 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
11581 use new diversions in preparation for accepting new arguments and

11595 2003-03-26 Derek Price <derek@ximbiot.com>
11597 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11598 sense. Verbosify the diversion definitions comment.
11600 2003-03-26 Derek Price <derek@ximbiot.com>
11602 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
11603 AS_PREPARE.

11624 file name for the m4 program, when it has an "exe" file extension.
11625 DJGPP's error messages include the error code in brackets -
11626 remove the error code during normalization.

11636 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11637 Tru64 make in the "target lookup" section.
11638 (Automake): Automake 1.5+ no longer requires special tools to be
11639 present on the developer's host.
11641 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11643 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

11656 to cope with DOS-style absolute paths, when constructing
11657 ${ac_make}.
11659 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11660 When constructing paths with IFS=:, quote the path. If we're
11661 constructing a DOS-style absolute path, we don't want to split it
11662 on the colon.
11664 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11665 in description.
11667 2003-02-25 Pavel Roskin <proski@gnu.org>
11669 * bin/autoheader.in: Add missing newline when printing
11670 suggestion how change AC_DEFINE call.
11672 2003-02-24 Paul Eggert <eggert@twinsun.com>
11674 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
11675 2002-09-01 patch by replacing "test -n" with "test -z".
11676 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
11677 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
11679 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11680 to fix a mismatch between example and discussion.
11682 2003-02-24 Kevin Ryde <user42@zip.com.au>
11684 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11685 format starting with "-".
11687 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11689 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11690 is not portable inside Makefile.
11692 2003-02-20 Akim Demaille <akim@epita.fr>
11694 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11695 compiler says yeah, but preproc says nope, compiler is right.
11696 Conversely, prompt the reader to send a bug report to the
11697 maintainers of the package, not of Autoconf.
11699 2003-02-20 Klee Dienes <kdienes@apple.com>
11701 * bin/autoreconf.in (autoreconf_current_directory): Properly
11702 handle an empty aclocal.m4.

11712 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11713 innocuous variant befor including <limits.h> or <assert.h>. This
11714 works around a bug reported by Albert Chin: HP-UX 11i
11715 (and earlier versions) have a <limits.h> that declares
11716 gettimeofday and many other functions.
11718 2002-12-03 Paul Eggert <eggert@twinsun.com>
11720 Version 2.57.
11722 * NEWS, configure.ac: Update version.
11724 * doc/fdl.texi: Upgrade to FDL version 1.2.
11726 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11727 nontrivially in main's body, so that f's external declaration is
11728 not optimized away in AIX. This should fix the bug reported by
11729 Martin Frydl in
11730 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11732 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11733 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11734 defined, to support freestanding compilers. This should fix the
11735 bug reported by Momchil Velkov in
11736 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11738 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11739 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11740 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11741 by Simon Josefsson in
11742 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11744 * Makefile.maint (www-gnu): New macro.
11745 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11746 the location has moved.
11748 2002-12-02 Martin Frydl <martin@systinet.com>
11750 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11751 \(.*\) match is too long and there is something more to be checked.
11752 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11754 2002-11-15 Akim Demaille <akim@epita.fr>
11756 Version 2.56.
11758 * config/install-sh: chmod +x.
11759 From Paul Eggert.
11760 * config/move-if-change: Indenting changes.
11761 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11762 * configure.ac (AM_INIT_AUTOMAKE): here.
11763 Require 1.7.1.
11765 2002-11-14 Akim Demaille <akim@epita.fr>
11767 Version 2.55.
11769 * config/config.guess, config/config.sub, config/install-sh:
11770 Update from masters.
11772 2002-11-14 Akim Demaille <akim@epita.fr>
11774 * Makefile.maint: Sync with Bison, i.e.:
11775 (po-check): Scan .l and .y files instead of the
11776 .c and the .h files that they generate. This fixes the bug
11777 reported by Tim Van Holder in:
11778 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11779 Look for N_ as well as for _. Try to avoid matching #define for
11780 N_ and _.
11781 From Paul Eggert.
11783 2002-11-14 Akim Demaille <akim@epita.fr>
11785 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11786 From Paul Eggert and Albert Chin-A-Young.
11788 2002-11-14 Akim Demaille <akim@epita.fr>
11790 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11791 From Paul Eggert and Albert Chin-A-Young.
11793 2002-11-14 Kevin Ryde <user42@zip.com.au>
11795 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11796 than assigning in main, to avoid HP cc +O3 optimizing it away.
11798 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11800 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11801 option. Process --recheck after parsing all options. Pass -q
11802 option to configure on --recheck.
11803 (AC_OUTPUT): Pass -q from configure to config.status.
11804 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11805 arguments to record.
11806 * doc/autoconf.texi (config.status Invocation): Document
11807 config.status -q option.
11809 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11811 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11812 Makefile.in if Makefile.am exists.
11813 (output): Strip `.am' from Makefiles. Don't
11814 output AC_CONFIG_FILES if no Makefiles were found.
11816 2002-11-07 Akim Demaille <akim@epita.fr>
11818 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

11825 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11826 declaration in extern "C" too.
11827 Reported by Roberto Bagnara.
11829 2002-11-06 Akim Demaille <akim@epita.fr>
11831 * tests/torture.at (Configuring subdirectories): Don't use grep
11832 -w.

11834 Reported by Ezra Peisach.
11836 2002-11-05 Akim Demaille <akim@epita.fr>
11838 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11839 Remove.
11840 We _have_ to stop using the old compatibility scheme that tried to
11841 avoid useless backslashes because Libtool 1.4.3 contains a
11842 AC_DEFINE([error_t], [int],
11843 [Define to a type to use for \`error_t' if it is not
11844 otherwise available.])
11845 We _have_ to quote the single quote and backslashes with \. The
11846 old compatibility scheme saw that ` was backslashed, and therefore
11847 did not quote the single quote. Hence before this patch, Autoconf
11848 was not compatible with Libtool.
11850 2002-11-04 Paul Eggert <eggert@twinsun.com>
11852 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11853 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11854 LC_NAME, LC_PAPER, LC_TELEPHONE.

11857 2002-11-04 Akim Demaille <akim@epita.fr>
11859 Version 2.54c.
11861 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11862 New.
11863 * config/texinfo.tex: Update.
11865 2002-11-03 Akim Demaille <akim@epita.fr>
11867 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11868 from...
11869 (&autoreconf): here.
11870 ($help, $make, &parse_args, &autoreconf_current_directory):
11871 Support -m/--make.
11872 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11874 2002-10-31 Bruno Haible <bruno@clisp.org>

11880 to ac_cv_func_realloc_0_nonnull.
11881 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
11883 2002-10-31 Akim Demaille <akim@epita.fr>
11885 The test suite was no longer checking for trailing envvars and files.
11887 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
11888 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11890 2002-10-31 Akim Demaille <akim@epita.fr>
11892 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11893 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11894 Make variable, not a shell variable.
11895 Suggested by Bruno Haible.
11897 2002-10-31 Akim Demaille <akim@epita.fr>
11899 * bin/autom4te.in (load_configuration): Reject #args out of any
11900 language.
11902 2002-10-31 Akim Demaille <akim@epita.fr>
11904 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
11905 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
11906 (_AC_RUN_IFELSE): Use it.
11907 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
11908 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
11909 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
11910 inline it.
11912 2002-10-30 Akim Demaille <akim@epita.fr>
11914 * bin/autom4te.in (&parse_args, $help): Support --no-cache.
11915 * doc/autoconf.texi (autom4te Invocation): Adjust.
11916 Suggested by Tim van Holder.
11918 2002-10-29 Paul Eggert <eggert@twinsun.com>
11920 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11921 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11922 Problem reported by Bruno Haible.
11924 2002-10-29 Akim Demaille <akim@epita.fr>
11926 * doc/autoconf.texi (Header Templates): Put also in words what the
11927 pictures says to assist free style readers.
11928 (Customizing autom4te): s/--cache=/--cache /.
11930 2002-10-29 Akim Demaille <akim@epita.fr>
11932 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
11933 sys/wait.h.
11934 sparc_address_test returns void.
11935 Use it with an argument, as prototyped.
11936 From Bruno Haible.
11938 2002-10-29 Akim Demaille <akim@epita.fr>
11940 * doc/autoconf.texi (Subdirectories): Cygnus dirs have
11941 configure.in, not configure.ac.

11946 * tests/torture.at (Deep Package): New test.
11947 (Configuring subdirectories): Don't use a testSubDir as Autotest
11948 now does it itself.

12180 2002-10-22 Akim Demaille <akim@epita.fr>
12182 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

12193 (_AS_QUOTE): Accept $2 as list of characters to quote.
12194 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
12195 Quote for Perl, not sh.
12196 * bin/autoheader.in: When $debug, report the file which is

12199 `@', to tickle Perl's lists.

12233 (ansi2knr.c-url_prefix): Remove.
12235 2002-10-16 Akim Demaille <akim@epita.fr>
12237 Because of caching, some files that no longer exist and are no
12238 longer required can still cause errors.
12239 Reported by Alexandre Duret-Lutz.
12241 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
12242 to frozen files in @ARGV, as @ARGV must remain being a list of
12243 files. Rather, at M4 call sites, use this...
12244 (&files_to_options): New function.
12245 (&freeze): Use &error.
12246 (&up_to_date): If a file that was included according to the cache
12247 is no longer there, then the output is out dated.

12249 --force is given.
12250 * tests/tools.at (autom4te cache): New.
12252 2002-10-16 Akim Demaille <akim@epita.fr>

12255 * bin/autoupdate.in (&parse_args): Kill old options.
12256 * bin/autoreconf.in (&parse_args): Remove dead options.
12257 Factor some code.
12258 (&autoreconf): Report the directories we enter *and leave*, so
12259 that error messages can be easily located, and use GNU Make
12260 format, so that Emacs' compile mode understands us.
12261 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12262 if some file was changed instead of `print'.
12263 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
12264 (&parse_args): Remove the dead options.

12277 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

12289 2002-10-11 Akim Demaille <akim@epita.fr>
12291 * tests/torture.at (AC_ARG_VAR): Have configure report the value
12292 of `precious'.
12294 2002-10-11 Akim Demaille <akim@epita.fr>
12296 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12297 file name to enable parallel executions.
12298 From Sam Varshavchik.
12300 2002-10-08 Akim Demaille <akim@epita.fr>
12302 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12303 aclocal invocation, as Gettext macros might not be visible to
12304 aclocal.
12305 Instead of blindly running autopoint, scan configure.ac (not the
12306 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12307 Reported by Paul D. Smith.
12309 2002-10-08 Paul Eggert <eggert@twinsun.com>
12311 Work around problems found when POSIXLY_CORRECT=1 is set.
12312 None of this seems to have anything to do with POSIX, really,
12313 but it's how Perl getopt works.
12314 * bin/autom4te.in (parse_args): Configure GetOpt with
12315 "permute", too.
12316 * doc/autoconf.texi (Invoking autom4te):
12317 --warning -> --warnings.
12318 * lib/autom4te.in: --warning -> --warnings.

12337 2002-09-28 Akim Demaille <akim@epita.fr>
12339 * tests/torture.at (Configuring subdirectories): Be robust to
12340 users who use config.site to require for a cache: in this case,
12341 the two last configure runs, using two different sets of
12342 arguments, trigger a legitimate error.
12344 2002-09-28 Akim Demaille <akim@epita.fr>
12346 * tests/m4sh.at (Functions Support, Functions and return Support):
12347 New.

12354 (autom4te): Specify that the sources are in the $srcdir.
12355 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12357 2002-09-28 Akim Demaille <akim@epita.fr>
12359 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
12360 (tm_zone): Move their rules to...
12361 * lib/autoconf/types.m4: here, using AN_ macros.
12362 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12363 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12364 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12365 * lib/autoconf/programs.m4: here.

12373 * lib/autoconf/autoconf.m4: Include it.
12374 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12375 that were listed in the original autoscan.list.
12376 * lib/autoconf/headers.m4: Similarly with headers.
12377 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12378 (.m4.m4f): Don't pass --prepend-include, since that's done by
12379 tests/autom4te itself.
12380 * lib/autoscan/Makefile.am: Include freeze.mk.
12381 (autoscan.list): New target --this file is no longer a source.
12382 (autoscan.pre): New file.
12384 2002-09-28 Akim Demaille <akim@epita.fr>
12386 * bin/autoscan.in (@kinds): Make them singular.
12387 Adjust all uses.
12388 (&init_tables): When --debug, report the list of rules to ease
12389 tracking changes in autoscan.list.
12390 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12392 2002-09-28 Akim Demaille <akim@epita.fr>

12398 * bin/autoscan.in (&init_tables): Adjust.
12400 2002-09-28 Akim Demaille <akim@epita.fr>
12402 * lib/autoscan/functions, lib/autoscan/headers,
12403 * lib/autoscan/identifiers, lib/autoscan/makevars,
12404 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12405 `functions' line is now prefixed with `function:'.
12406 * bin/autoscan.in (&init_tables): Adjust.
12408 2002-09-28 Akim Demaille <akim@epita.fr>
12410 From now on, autoscan files must always map a macro name to a
12411 word: there is no `default' macro for autoscan.
12413 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12414 all.

12421 (&used): Keep only track of the words we might be interested in.
12422 (&output_kind): It is no longer needed to look for non active
12423 checks.
12425 2002-09-27 Akim Demaille <akim@epita.fr>
12427 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12428 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12429 * lib/autoscan/functions: Adjust.

12435 from /tmp.
12436 Thanks to Bill Moseley and Paul Eggert.

12438 the tmpdir must be created.
12439 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12440 dir be in the build tree, instead of $TMPDIR.

12453 Reported by Ralf Corsepius.
12454 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12456 2002-09-26 Akim Demaille <akim@epita.fr>

12462 Separated Dependencies'.
12463 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12464 (ifnames, autoscan, autom4te): Un-factor into several rules.
12466 2002-09-25 Paul Eggert <eggert@twinsun.com>
12468 * BUGS (Interoperability bugs): New section. Mention libtool
12469 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12471 2002-09-24 Paul Eggert <eggert@twinsun.com>
12473 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12474 make handles suffix-rules differently from GNU make.

12480 2002-09-16 Akim Demaille <akim@epita.fr>
12482 i960 compilers create `b.out' files by default.
12483 Reported by Ralf Corsepius.
12485 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12486 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12488 2002-09-13 Paul Eggert <eggert@twinsun.com>
12490 * doc/autoconf.texi (Particular Headers): Remove obsolete
12491 reference to `struct timezone' in the description of
12492 AC_HEADER_TIME.
12494 2002-09-13 Akim Demaille <akim@epita.fr>
12496 Version 2.54.
12498 * config/config.sub, config/config.guess: Update.
12499 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12500 * Makefile.am: Adjust.
12502 2002-09-13 Akim Demaille <akim@epita.fr>
12504 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12505 reading config.log when the compiler is rejected.
12506 Suggested by Guido Draheim.
12508 2002-09-13 Akim Demaille <akim@epita.fr>
12510 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12511 (chdir_init) might hang when stat'ing mounted directories.
12512 Reported by Vance Shipley.
12514 2002-09-12 Akim Demaille <akim@epita.fr>
12516 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12517 the lists.
12519 2002-09-12 Akim Demaille <akim@epita.fr>
12521 * doc/autoconf.texi (Defining Symbols): Present two different
12522 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12523 difference between 1 argument calls, and 2-3 argument calls.
12525 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12527 * doc/autoconf.texi: Review grammar and punctuation.
12529 2002-09-11 Paul Eggert <eggert@twinsun.com>
12531 * doc/autoconf.texi: Fix minor formatting, spelling, and
12532 grammatical typos.
12533 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12534 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12535 is obsolescent.
12537 2002-09-11 Akim Demaille <akim@epita.fr>
12539 * doc/autoconf.texi (Questions): Rename as...
12540 (FAQ): this.
12541 (Defining Directories): New.
12543 2002-09-09 Akim Demaille <akim@epita.fr>
12545 * doc/autoconf.texi (Making testsuite Scripts): Update.
12546 Suggested by Nishio Futoshi.
12548 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12550 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12551 plain `@' is wanted.
12553 2002-09-09 Akim Demaille <akim@epita.fr>
12555 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12556 `duplicates', since the algorithm was too naive and could keep
12557 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12558 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12559 Reported by Ralf Corsepius.
12560 * tests/torture.at (Configuring subdirectories): Exercise these
12561 cases.
12563 2002-09-09 Akim Demaille <akim@epita.fr>
12565 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12566 looking for a replacement file.
12567 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12568 directory is relative.
12569 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12570 directory definition.
12571 Reported by Andreas Schwab and Jim Meyering.
12573 2002-09-06 Akim Demaille <akim@epita.fr>
12575 * doc/autoconf.texi (Setting Output Variables): Clarify what
12576 precious variables are.
12577 Suggested by Pontus Skoeld.
12579 2002-09-05 Akim Demaille <akim@epita.fr>
12581 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12582 (ifnames, autoscan, autom4te): Since we don't only depend on
12583 configure.ac variables (such as VERSION etc.), but also on prefix
12584 and so forth, depend on Makefile, not configure.ac.
12585 Reported by Alexandre Duret-Lutz.
12586 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12588 2002-09-05 Kevin Ryde <user42@zip.com.au>
12590 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12591 doesn't seem to be confined to ia64, just say "some versions".
12593 2002-09-04 Akim Demaille <akim@epita.fr>
12595 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12596 Automake 1.6c.
12597 * Makefile.am (maintainer-clean-local): Remove.
12598 (MAINTAINERCLEANFILES): Remove COPYING.
12600 2002-09-03 Paul Eggert <eggert@twinsun.com>
12602 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12603 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12604 Brinkmann.
12606 2002-09-03 Akim Demaille <akim@epita.fr>
12608 * configure.ac: Bump to 2.53d.
12609 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12610 as of today, on Automake's team suggestion.
12612 2002-09-03 Akim Demaille <akim@epita.fr>
12614 Version 2.53c.
12616 2002-09-02 Akim Demaille <akim@epita.fr>
12618 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12619 SITE_MACRO_DIR.
12620 * configure.ac: Disable SITE_MACRO_DIR.
12622 2002-09-02 Jim Meyering <meyering@lucent.com>
12624 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12625 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12626 Also, tweak grammar: s/make sure to/be sure to/.
12628 2002-09-02 Paul Eggert <eggert@twinsun.com>
12630 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12631 directory names are generally preferable to physical names.
12633 2002-09-02 Akim Demaille <akim@epita.fr>
12635 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12636 Reported by Raja R. Harinath.
12637 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12638 * bin/autoupdate.in: Use error instead of die.
12640 2002-09-01 Paul Eggert <eggert@twinsun.com>
12642 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12643 ordinary shell concatenation rather than echo+tr+sed command that
12644 runs afoul of a long-line-related sed bug in Solaris 8.
12646 * bin/autoheader.in (parse_args): --warning -> --warnings.
12648 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12649 stdout, as traditional "ls" does.
12650 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12651 _AC_COMPILER_EXEEXT_O): Likewise.
12652 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12654 * bin/autoconf.as: Add --prepend-include option. This patch was
12655 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12656 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12658 * bin/autoconf.in, configure: Regenerate.
12660 * doc/autoconf.texi (Special Shell Variables): Mention
12661 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12663 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12664 MAILPATH and set PS1, PS2, PS4 to default values, to work
12665 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12666 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12667 the Autoconf documentation specifies; fall back to "unset" only if
12668 this fails. Use a shell for-loop for this rather than an m4 loop,
12669 to shorten the output script.
12671 2002-08-30 Paul Eggert <eggert@twinsun.com>
12673 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12674 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12675 for the CDPATH problem. Document PWD.
12676 (Limitations of Builtins): Document the problem that "cd $foo" and
12677 "ls $foo" may refer to different directories in shells conforming
12678 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12679 example, since the old example is now out of date.
12681 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12682 FOO" and "ls FOO" talk about different directories; this catches
12683 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12684 spaghetti.
12686 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12687 of rolling our own unset.
12688 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12689 in practice we needn't worry about CDPATH if unset doesn't work.
12691 * Makefile.in, aclocal.m4, bin/Makefile.in,
12692 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12693 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12694 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12695 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12696 tests/Makefile.in: Regenerate with Automake 1.6.3.
12698 * config/config.guess, config/config.sub, config/mkinstalldirs:
12699 Update.
12701 * configure: Regenerate with self.
12703 2002-08-30 Kevin Ryde <user42@zip.com.au>
12705 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12706 default output.
12708 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12710 * bin/autom4te.in (Request::load): Correctly test for "do" read
12711 failure.
12713 2002-08-29 Akim Demaille <akim@epita.fr>
12715 * lib/Autom4te/General.pm (&xqx): New.
12716 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12717 hand, which is not portable.
12718 (&error): New.
12719 * bin/autom4te.in: Use them.
12720 Use &error instead of die.
12721 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12722 Adjust.
12724 2002-08-17 Paul Eggert <eggert@twinsun.com>
12726 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12727 default list of compilers to try, since it was long ago superseded
12728 by the ksh fc builtin. Suggested by Steven G. Johnson.
12730 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12732 * doc/autoconf.texi (Invoking autom4te): End the option table,
12733 fixing a bug introduced by the previous patch.
12734 (Limitations of Make): Add a 'target lookup' subentry in the
12735 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12737 2002-07-29 Mark D. Roth <roth@feep.net>
12739 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12740 options and use $AUTOM4TE_PATH.
12741 * doc/autoconf.texi: Remove documentation of autom4te
12742 --include-envvar and --site-macro-subdir options and document
12743 use of $AUTOM4TE_PATH.
12744 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12745 arguments from each language section.
12747 2002-07-29 Paul Eggert <eggert@twinsun.com>
12749 * doc/install.texi: Include copyright symbol in copyright notice.
12751 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12752 Replace with:
12753 (AM_MAKEINFOFLAGS): New macro.
12754 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12755 * Makefile.am (INSTALL): Use the new macros.
12756 Use -o rather than --output, since "missing" does not grok --output.
12758 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12760 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12761 comments do not always work. Never trust the exit status of
12762 `make -k'.
12764 2002-07-24 Kevin Ryde <user42@zip.com.au>
12766 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12767 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12769 2002-07-23 Paul Eggert <eggert@twinsun.com>
12771 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12772 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12773 apparently treats PATH="nonexistent" as if it contained ".".
12774 Bug reported by Stefan `Sec' Zehl.
12776 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12778 * doc/autoconf.texi (Limitations of Make): Mention the special
12779 handling of the obj/ directory by BSD make.
12781 2002-07-20 Kevin Ryde <user42@zip.com.au>

12784 backslashes.

12791 2002-07-19 Akim Demaille <akim@epita.fr>
12793 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
12795 2002-07-18 Akim Demaille <akim@epita.fr>
12797 Version 2.53b.
12799 2002-07-18 Akim Demaille <akim@epita.fr>
12801 * config/config.guess, config/config.sub: Update.
12803 2002-07-18 Akim Demaille <akim@epita.fr>
12805 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
12806 Automake's parts.

12809 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
12810 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
12812 2002-07-18 Akim Demaille <akim@epita.fr>,

12825 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12826 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12827 latter was not run.
12829 2002-07-17 Akim Demaille <akim@epita.fr>
12831 * lib/Autom4te/General.pm (find_file): Browse the directories in
12832 the order they are given.
12834 2002-07-17 Akim Demaille <akim@epita.fr>

12852 macro directory, remove note that include path directories are

12854 * lib/autom4te.in: Use --prepend-include instead of --include.
12855 * tests/wrapsh.in: Use --prepend-include instead of --include.
12857 2002-07-17 Akim Demaille <akim@epita.fr>
12859 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in

12912 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12913 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12914 so that we consistently test the just-built programs.
12915 * tests/wrappl.as: Likewise.
12917 2002-06-12 Paul Eggert <eggert@twinsun.com>
12919 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

12933 * doc/autoconf.texi: Add more dir entries.
12935 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12937 * bin/autom4te.in ($cache): Don't define using `$me', the name
12938 of the cache should not depend on the name under which autom4te
12939 was installed.
12941 2002-06-07 Akim Demaille <akim@epita.fr>

12967 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12968 suggest m4_pattern_allow.
12969 Suggested by Adam J. Richter.
12971 2002-06-07 Akim Demaille <akim@epita.fr>
12973 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12974 ac_config_libobj_dir.
12975 (AC_CONFIG_LIBOBJ_DIR): New.
12976 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

12983 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
12984 * tests/mktests.sh (ac_exclude_list): Don't check
12985 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
12987 2002-06-06 Paul Eggert <eggert@twinsun.com>

13034 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
13035 from the default list of compilers to try. Suggested by
13036 Kate Hedstrom.
13037 * NEWS: Document the above.
13038 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
13040 2002-05-17 Paul Eggert <eggert@twinsun.com>
13042 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
13043 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
13044 This improves on an earlier suggestion by H. Peter Anvin.
13046 2002-05-16 Paul Eggert <eggert@twinsun.com>
13048 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13049 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13050 Both macros now accept an optional source-dir arg.
13051 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13053 * NEWS: Document this.
13054 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13056 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13057 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13058 not for GNU extensions; this undoes part of the 2000-11-03 change,
13059 reverting to 2.13-compatible behavior.
13060 Add new optional argument DIR.
13061 (AC_FUNC_FNMATCH_GNU): New macro.
13063 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
13065 2002-05-08 Paul Eggert <eggert@twinsun.com>
13067 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13068 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13069 and it causes a 'test' syntax error if it fails.
13070 Bug reported by Stephen Gildea.
13072 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13073 If prototypes are supported, use them to check this at compile-time,
13074 instead of trying to check it at run-time. If we must do a run-time
13075 check, assume that setvbuf is standard when cross-compiling, as
13076 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13077 Bug reported by Paul D. Smith.
13079 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13080 argument specifying location of getloadavg.c. This removes a
13081 FIXME. This idea was taken from Jim Meyering's implementation in
13082 textutils.
13083 * doc/autoconf.texi (Particular Functions): Document this.
13084 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13085 that's what the code does; this fixes a bug reported by
13086 Paul D. Smith.
13088 2002-05-03 Akim Demaille <akim@epita.fr>
13090 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13091 autopoint instead of gettextize.
13092 ($uses_alocal): Rename as...
13093 ($uses_aclocal): this.
13094 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13095 Suggested by Bruno Haible.
13097 2002-05-03 Akim Demaille <akim@epita.fr>
13099 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13101 2002-04-29 Paul Eggert <eggert@twinsun.com>
13103 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13104 files to be 1 second older; just set them to be the same time.
13105 Also, sleep 1 second after the first aclocal, to work around
13106 problems with sub-second time stamps on the input files.
13108 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13110 * doc/autoconf.texi: Mention "set -e -x" lossage
13111 under node "Limitations of Builtins".
13113 2002-04-29 Akim Demaille <akim@epita.fr>
13115 * doc/install.texi: Better wording for setting variables when
13116 running configure.
13117 From Christian Cornelssen.
13119 2002-04-29 Akim Demaille <akim@epita.fr>
13121 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13122 of lack of $LINENO support, then the test will compare the $LINENO
13123 in testsuite vs. the lineno in the test file. This is wrong, of
13124 course.
13125 Be sure to protect it.
13126 Reported by Patrick Welche.
13128 2002-04-25 Akim Demaille <akim@epita.fr>
13130 * doc/autoconf.texi (Obsolete Macros): Typo.
13131 Reported by Vladimir Volovich.
13133 2002-04-25 Akim Demaille <akim@epita.fr>
13135 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13136 than some of the input files, hence, on the second run of aclocal,
13137 if some of its input are younger, make them older.
13138 Suggested by Paul Eggert.
13140 2002-04-25 Akim Demaille <akim@epita.fr>
13142 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
13143 Thanks to Paul Eggert.
13145 2002-04-25 Akim Demaille <akim@epita.fr>
13147 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
13148 and ac_subst_vars be sh variables containing the list of
13149 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13150 DEFAULT diversion.
13151 (_AC_INIT_PREPARE): Use them to log them.
13152 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13153 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13154 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13155 _AC_SUBST_FILES and _AC_SUBST_VARS.
13156 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13158 2002-04-24 Akim Demaille <akim@epita.fr>
13160 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13161 autoheader, so that automake does not complain about a missing
13162 config.h.in that was to be created.
13164 2002-04-23 Akim Demaille <akim@epita.fr>
13166 * bin/autoheader.in (parse_args): --warning takes an argument.
13167 Fixes PR/220.
13169 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
13171 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

13216 Minor spelling and grammar fixes.
13218 * doc/autoconf.texi: Follow the outline suggested in the GNU
13219 Sample Texts sections of the Texinfo 4.2 manual. Most
13220 importantly, this makes sure that the copyright notices appear in
13221 all output formats. You probably need Texinfo 4.2 to generate
13222 the manual now.
13224 Fix some bugs when using "$@" when there might be zero positional

13250 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

13273 Adjust Autoconf and Autotest.

13276 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13277 * lib/autotest/general.m4 (AT_INIT): Likewise.
13278 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

13323 Extracted from...
13324 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13325 (AC_CONFIG_LINKS): here.
13326 Adjust.
13327 Don't use the KILL diversion, as it kills spurious output, which
13328 results in failures being hidden.
13329 Use m4_defn where appropriate.
13330 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13331 after the second argument.
13332 Use m4_defn.
13333 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning

13358 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13359 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13360 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13361 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13362 (AC_C_CONST): Same.
13363 (AC_C_INLINE): Same.
13364 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
13365 * doc/autoconf.texi, NEWS: Document.
13366 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
13367 AC_C_CROSS.
13369 2002-04-02 Akim Demaille <akim@epita.fr>
13371 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
13372 _AS_MKDIR_P_PREPARE.
13374 2002-03-28 Kevin Ryde <user42@zip.com.au>
13376 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13377 to avoid versions of HP C which don't allow that.
13379 2002-03-27 Paul Eggert <eggert@twinsun.com>
13381 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13382 (AS_SHELL_SANITIZE): Invoke it.
13383 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13385 2002-03-26 Akim Demaille <akim@epita.fr>
13387 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13389 2002-03-26 Akim Demaille <akim@epita.fr>
13391 * doc/autoconf.texi (Introduction): The GNATS base moved.
13393 2002-03-25 Paul Eggert <eggert@twinsun.com>
13395 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13396 as POSIX requires, as it doesn't work with Zsh.
13397 * doc/autoconf.texi (Assignments): Document the problem.
13399 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13401 * doc/autoconf.texi (Limitations of Make): Mention more issue
13402 about VPATH, overriding of macros in sub-makes, and handling of
13403 SHELL.
13405 2002-03-21 Paul Eggert <eggert@twinsun.com>
13407 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13408 problem with here-document buffer boundaries.
13410 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13411 when reinvoking the shell, to work around problems with installers
13412 who put strange things like "cd" commands in their environments.
13414 2002-03-19 Akim Demaille <akim@epita.fr>
13416 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13417 From Aaron Ucko.
13419 2002-03-19 Akim Demaille <akim@epita.fr>
13421 * bin/autoscan.in (scan_file): Specify the location in `&used'
13422 invocations.
13423 From Nicolas Joly.
13425 2002-03-19 Akim Demaille <akim@epita.fr>
13427 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13428 From Nishio Futoshi.
13430 2002-03-19 Akim Demaille <akim@epita.fr>
13432 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13434 2002-03-18 Paul Eggert <eggert@twinsun.com>
13436 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13437 (Limitations of Usual Tools): Add mkdir section.
13439 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13440 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13441 back on AS_DIRNAME to compute prefixes otherwise; this is
13442 roughly what mkinstalldirs does. That way, we need not have
13443 our own filename disassembler. The old disassembler did not
13444 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13446 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13447 Create at_test_all by a series of assignments,
13448 not by a single assignment of a long string. The latter causes ksh
13449 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13450 presumably because of a buffer overrun.
13452 2002-03-14 Paul Eggert <eggert@twinsun.com>
13454 * lib/autotest/general.m4 (at_times_skip):
13455 Renamed from at_times. Now a boolean.
13456 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13457 says 'times: not found'.
13459 2002-03-14 Akim Demaille <akim@epita.fr>
13461 * bin/autoreconf.in (&study_gettextize): New.
13462 (&autoreconf): Handle newest gettextize.
13463 Rerun aclocal if needed.
13464 Suggested by Andreas Schwab.
13466 2002-03-13 Akim Demaille <akim@epita.fr>
13468 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13470 2002-03-13 Akim Demaille <akim@epita.fr>
13472 * doc/autoconf.texi (Header Portability): New.
13473 Add information about stdint.h and inttypes.h from Paul Eggert.
13475 2002-03-13 Akim Demaille <akim@epita.fr>
13477 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13478 -p'.
13479 From Bob Proulx.
13481 2002-03-12 Akim Demaille <akim@epita.fr>
13483 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13484 m4_require.
13486 2002-03-11 Andreas Schwab <schwab@suse.de>
13488 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13489 does not do it if --with-lispdir is given.
13491 2002-03-08 Akim Demaille <akim@epita.fr>
13493 Version 2.53.
13495 2002-03-08 Akim Demaille <akim@epita.fr>
13497 * doc/autoconf.texi (Subdirectories): Clarify that the
13498 subdirectory should exist.
13500 2002-03-08 Akim Demaille <akim@epita.fr>
13502 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13504 2002-03-08 Akim Demaille <akim@epita.fr>
13506 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13507 aliases the actual variables, and modifications of the former
13508 affect the latter.
13510 2002-03-08 Akim Demaille <akim@epita.fr>
13512 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13513 because of C-c: have m4 output in tmp files, then mv them.
13515 2002-03-08 Akim Demaille <akim@epita.fr>
13517 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13518 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13519 * bin/ifnames.in: Copyright update.
13521 2002-03-08 Akim Demaille <akim@epita.fr>
13523 * doc/autoconf.texi (Invoking autom4te): New.
13525 2002-03-05 Akim Demaille <akim@epita.fr>
13527 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13528 Kevin Ryde.
13530 2002-03-05 Akim Demaille <akim@epita.fr>
13532 Version 2.52i.
13534 2002-03-04 Akim Demaille <akim@epita.fr>
13536 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13537 * lib/autoconf/general.m4 (AC_INIT): More informative error
13538 message for LIBOBJ.
13540 2002-03-04 Akim Demaille <akim@epita.fr>
13542 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13543 parallel builds.
13545 2002-03-04 Akim Demaille <akim@epita.fr>
13547 * doc/autoconf.texi (Transforming Names): Equality between target
13548 and host is irrelevant.
13549 (Specifying Names, Canonicalizing): Remove all references to the
13550 backward compatibility hooks. Rather, collect them all into...
13551 (Hosts and Cross-Compilation): this new section.
13552 * doc/install.texi (System Type): Ditto.
13553 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13554 that `--host' implies cross-compilation.
13556 2002-03-04 Akim Demaille <akim@epita.fr>
13558 * doc/autoconf.texi (Evaluation Macros): New.
13559 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13560 useless.
13561 (_m4_foreach): Define the variant with immediate evaluation so
13562 that it contains exactly the items, not an expression which
13563 evaluation is the current item.
13564 (m4_re_string, m4_re_word): Don't over quote them.
13566 2002-03-04 Akim Demaille <akim@epita.fr>
13568 Instead of having stacking `shift's evaluated at the end, let
13569 `foreach' loops immediately evaluate them.
13571 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13572 $*. This is the n-th time I change my mind, but hopefully this is
13573 the last...
13574 (m4_lquote): New.
13575 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13576 efficient.
13577 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13578 it was only a hack for m4_text_wrap.
13579 (m4_car2): Remove, replaced by...
13580 (m4_cdr): New.
13581 (_m4_foreach): Adjust.
13582 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13583 m4_bpatsubst for clarification.
13585 2002-03-04 Akim Demaille <akim@epita.fr>
13587 * doc/autoconf.texi (Changequote is Evil): New.
13589 2002-03-03 Kevin Ryde <user42@zip.com.au>
13591 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
13592 on old systems like SunOS.
13594 2002-03-01 Peter Eisentraut <peter_e@gmx.net>

13614 From Akinori Musha.
13616 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
13618 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
13619 translate \r\n to \n.
13621 2002-02-07 Akim Demaille <akim@epita.fr>
13623 Version 2.52h.
13625 2002-02-07 Akim Demaille <akim@epita.fr>
13627 Fix Autoconf PR/209.
13628 Also reported by Frank Denis.
13630 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13632 2002-02-07 Akim Demaille <akim@epita.fr>
13634 Fix Autoconf PR/207:
13635 AC_PREFIX_PROGRAM fails with dashed program names
13637 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13638 variable when looking for the prefix program.
13639 Now it also works for shell variables.
13641 2002-02-07 Akim Demaille <akim@epita.fr>
13643 * doc/autoconf.texi (Limitations of Builtins): More about
13644 case/esac.

13648 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
13649 case/esac, some shells don't support it.
13650 Reported by Zack Weinberg.

13653 2002-02-06 Akim Demaille <akim@epita.fr>
13655 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
13656 sure not to introduce newlines in at_groups.
13657 * lib/autotest/Makefile.am (autotest.m4f): Typo.
13659 2002-02-06 Akim Demaille <akim@epita.fr>
13661 * tests/torture.at (Configuring subdirectories): Skip if aclocal
13662 is not available.
13664 2002-02-05 Paul Eggert <eggert@twinsun.com>
13666 * doc/autoconf.texi (Specific Compiler Characteristics):
13667 Describe HP-UX cc bug workaround more accurately.
13668 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13669 not unsigned long.
13670 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13671 cross-compilers, too. This undoes some of the most recent change
13672 to this file.
13674 2002-02-05 Akim Demaille <akim@epita.fr>
13676 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13677 to make sure they are up to date when `check' is run.

13681 * doc/autoconf.texi (Making testsuite Scripts): Document

13686 * lib/freeze.mk: New.
13688 2002-02-05 Akim Demaille <akim@epita.fr>
13690 Implement `autom4te --freeze'.
13692 * bin/autom4te.in (&freeze): New.
13693 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13694 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13696 2002-02-05 Akim Demaille <akim@epita.fr>
13698 * bin/autom4te.in (&parse_args): Implement `frozen files are
13699 optional are the sum of the previous files on the command line'.
13700 Also, pass `--reload-state=' on them, so...
13701 (handle_m4): don't.
13702 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13703 (M4sh): Rely on M4sugar.
13704 (Autotest, M4sh, M4sugar): Use frozen files.
13706 2002-01-31 Akim Demaille <akim@epita.fr>
13708 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13709 * doc/autoconf.texi (Initializing configure): Adjust.
13711 2002-01-30 Akim Demaille <akim@epita.fr>
13713 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13714 alphanumeric to `-' instead of `_'.
13716 2002-01-30 Akim Demaille <akim@epita.fr>
13718 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13719 for plain code, the other for cross-compilation code. The latter
13720 is now run with GCC only.
13721 * doc/autoconf.texi (Compilers and Preprocessors): New.
13723 2002-01-30 Akim Demaille <akim@epita.fr>
13725 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13726 values.
13727 * doc/autoconf.texi (Initializing configure): Explain how to
13728 change AC_INIT default values.
13730 2002-01-29 Akim Demaille <akim@epita.fr>
13732 * tests/torture.at (Configuring subdirectories): Use configure.in,
13733 so that aclocal 1.4 works.
13734 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13736 2002-01-28 Akim Demaille <akim@epita.fr>
13738 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13739 needs an argument.
13741 2002-01-28 Akim Demaille <akim@epita.fr>
13743 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13744 AUTOTEST_PATH *after* it was set.
13745 Don't put `.' in the PATH: the user should be precise and `./' if
13746 needed. In addition, given that the test suite does some `cd', if
13747 `.' is in the path, the `tested programs' sections will report
13748 programs found in the test suite's directory, while during the
13749 tests (performed in their own directory), these programs are no
13750 longer visible. In other words, the results is confusing and
13751 useless.
13752 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13754 2002-01-24 Akim Demaille <akim@epita.fr>

13761 * doc/autoconf.texi: Finally add Akim as an author.
13763 2002-01-24 Akim Demaille <akim@epita.fr>
13765 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13766 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13767 Bourne. Use /bin/sh.
13768 From Andreas Buening.
13770 2002-01-24 Akim Demaille <akim@epita.fr>
13772 * config/config.guess, config/config.sub, config/texinfo.tex:

13782 Automake.
13784 2002-01-24 Akim Demaille <akim@epita.fr>
13786 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13787 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13788 Reported by Geir Ove Myhr.
13790 2002-01-21 Akim Demaille <akim@epita.fr>
13792 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13794 2002-01-21 Akim Demaille <akim@epita.fr>
13796 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13797 message on invalid options.
13798 * bin/autom4te.in (parse_args): Don't use
13799 Autoconf::General::getopt with non valid options.
13801 2002-01-17 Jim Meyering <meyering@lucent.com>
13803 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13804 $ac_cv_exeext so we don't use an old, invalid, cached value.
13806 2002-01-11 Akim Demaille <akim@epita.fr>
13808 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13809 Meyering.
13810 * doc/autoconf.texi (Function Portability): Document the strnlen
13811 limitation.
13812 (Particular Functions): Document AC_FUNC_STRNLEN.
13813 * lib/autoscan/functions: Adjust.
13815 2002-01-06 Akim Demaille <akim@epita.fr>
13817 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13818 package.m4, since is really depends upon configure.ac, not
13819 configure.
13820 * doc/autoconf.texi (testsuite Scripts): Adjust.
13821 * tests/Makefile.am (package.m4): New.
13822 EXTRA_DIST it since its a source.
13824 2002-01-06 Akim Demaille <akim@epita.fr>
13826 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13827 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13828 and PACKAGE_BUGREPORT from here...
13829 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13830 arguments.
13831 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13832 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13833 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13834 * tests/tools.at (autoheader): Adjust.
13835 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13837 2002-01-06 Akim Demaille <akim@epita.fr>

13843 * doc/autoconf.texi (Output): Improved wording regarding use of
13844 AC_OUTPUT.
13845 From Olly Betts.
13847 2001-12-18 Kevin Ryde <user42@zip.com.au>
13849 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13850 sometimes needing writable input.
13852 2001-12-17 Jim Meyering <meyering@lucent.com>
13854 * doc/autoconf.texi (New Macros): Tweak wording.
13856 2001-12-14 Akim Demaille <akim@epita.fr>
13858 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13859 trailing files, don't apply `-rf' to files which might not be
13860 created by configure (core, core.*, and *.core), but just `rm -f'.
13861 Suggested by Jonathan Kamens.
13863 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13865 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13867 2001-12-14 Akim Demaille <akim@epita.fr>
13869 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13871 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13873 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13874 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13875 abs_srcdir, top_srcpath to abs_top_srcdir.
13876 (_AC_OUTPUT_FILES): Adjust.
13877 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13878 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13879 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13881 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13883 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13884 C/Fortran linking on HP/UX, by extracting the Fortran library
13885 search path from the LPATH line in the $F77 -v output.
13887 2001-12-12 Kevin Ryde <user42@zip.com.au>
13889 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13890 forbidden file descriptors table.
13892 2001-11-26 Akim Demaille <akim@epita.fr>
13894 * bin/autoscan.in (%c_keywords): Build it at top level.
13895 Map to 1 in order to simplify its uses.
13897 2001-11-26 Akim Demaille <akim@epita.fr>
13899 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13900 Remove $filepath, useless.
13901 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13902 variables, they are really part of the tokens.
13903 Split the input line on spaces and then look for tokens.
13904 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13905 because of `lex$U.$(OBJEXT)'.
13906 (&scan_files): Use "@list" instead of join.
13907 * doc/Makefile.am (CLEANFILES): Add *.fns.
13909 2001-11-26 Akim Demaille <akim@epita.fr>
13911 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13912 Remove, replaced by...
13913 * tests/wrappl.in: Be common for all the Perl executables.
13914 In particular autoscan and autoheader want -I.
13915 * configure.ac: Adjust.
13916 * lib/autoscan/headers: errno.h is portable.
13918 2001-11-26 Akim Demaille <akim@epita.fr>
13920 * bin/autoscan.in (used): New.
13921 Use it.
13923 2001-11-26 Akim Demaille <akim@epita.fr>
13925 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13926 directives.
13927 (&scan_sh_file): Remove a duplicate pattern.
13928 (&check_configure_ac): Use long options.
13929 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13931 2001-11-26 Akim Demaille <akim@epita.fr>
13933 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13934 Before, having a line containing the opening of a multi line
13935 comment made the whole line be ignored.
13937 2001-11-26 Akim Demaille <akim@epita.fr>
13939 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13940 (testsuite Scripts): Be one of its subsection.
13941 (Autotest Logs): New.
13943 2001-11-26 Akim Demaille <akim@epita.fr>
13945 Test groups are now run two directories deeper.
13947 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13948 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13949 at_top_builddir.
13950 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13951 top_srcdir, builddir and top_builddir.
13952 Use `at_*dir' relatively to the directory containing the
13953 suite, use `*dir' when relatively to the current group dir.
13955 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13957 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13958 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13959 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13960 spelling errors.
13962 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13964 * doc/autoconf.texi (Using System Type): Add an example of `case
13965 $host' usage so people quit using `case $target' everywhere.
13967 2001-11-22 Akim Demaille <akim@epita.fr>
13969 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13970 spotted by Jim Meyering.
13972 2001-11-16 Paul Eggert <eggert@twinsun.com>
13974 This patch implements a `long double' suggestion by Oliver Kiddle.
13976 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13977 static, to catch errors if the value isn't known at compile-time
13978 and the compiler supports dynamic arrays. Change its name from
13979 `_array_' to `test_array' to avoid potential name clashes.
13980 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13981 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13982 better than double. Catch a bug in GCC 2.95.2 x86.
13983 * doc/autoconf.texi (C Compiler): Document the above.
13984 * NEWS: Likewise.
13986 2001-11-13 Akim Demaille <akim@epita.fr>
13988 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13989 hand.
13990 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13992 2001-11-13 Akim Demaille <akim@epita.fr>
13994 * lib/autotest/general.m4 (AT_INIT): After having run the test
13995 group, go back to the initial directory, not to at_suite_dir.
13997 2001-11-13 Akim Demaille <akim@epita.fr>
13999 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14000 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14001 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14002 option.
14003 (AT_CHECK_CONFIGURE): Use absolute paths.
14004 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14005 The problem is still the old one: there is no means in M4 (that I
14006 know about) to create a defining macro, because there is no means
14007 to create `$1' etc., therefore, the defining macro ``swallows''
14008 all the arguments meant to the defined macro.
14010 2001-11-13 Akim Demaille <akim@epita.fr>
14012 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14013 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14014 configure.ac.
14015 * tests/aclocal.m4: Remove, as it is no longer used.
14017 2001-11-13 Akim Demaille <akim@epita.fr>
14019 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14020 variable names when referring to a single test group, or to
14021 `suite' when referring to the whole test suite.
14022 `at_last_test' is removed: m4 compute at_format itself.
14023 (at_stdout, at_stder1, at_stderr): New variables.
14024 (AT_CHECK): Use them.
14026 2001-11-13 Akim Demaille <akim@epita.fr>
14028 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14029 in PATH.
14030 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14031 Do it as soon as a test fails, don't wait till the end of the test
14032 suite.
14033 Don't remove $as_me.[0-9]*, since these files no longer exist.
14035 2001-11-13 Akim Demaille <akim@epita.fr>
14037 * tests/tools.at: Use absolute paths, since we are no longer run
14038 in place.
14040 2001-11-13 Akim Demaille <akim@epita.fr>
14042 Now that tests are running in their own private dir, there is no
14043 need to list the files to remove at the end of tests groups.
14045 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14046 (AT_data_files, at_data_files): Remove.
14047 (AT_CLEANUP, AT_DATA): Simplify.
14048 (AT_INIT): Adjust.
14049 Remove the group dir if !debug && !failed.
14050 * tests/atspecific.m4: Adjust.
14052 2001-11-13 Akim Demaille <akim@epita.fr>
14054 Start a new layout for Autotest: `testsuite' creates
14055 `testsuite.dir' in which the at-check-line etc. files are to be
14056 found, and `testsuite.dir/003' where the test group 3 is run.
14058 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14059 at_check_line_file, at_format, at_test_normalized, at_group_dir
14060 are new variables.
14061 Create the directories.
14062 Use absolute paths for at- files.
14063 (AT_CHECK): Adjust.
14065 2001-11-11 Michael Matz <matz@kde.org>
14067 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14068 (m4_car2): New.
14069 (m4_car): Properly quote arguments.
14071 2001-11-13 Akim Demaille <akim@epita.fr>
14073 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14074 with stricter rules on LIBOBJS.
14076 2001-11-12 Paul Eggert <eggert@twinsun.com>
14078 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14079 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14080 __PROTOTYPES too.
14082 2001-11-12 Akim Demaille <akim@epita.fr>
14084 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14086 2001-11-12 Akim Demaille <akim@epita.fr>
14088 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14089 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14090 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14091 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14092 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14093 specify to what the macro should be defined (typically to 1).
14095 2001-11-12 Akim Demaille <akim@epita.fr>
14097 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14098 From Jim Meyering.
14100 2001-11-12 Akim Demaille <akim@epita.fr>
14102 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14103 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14104 definition used by Automake where LEX is +/- "${missing} lex" and
14105 `missing' itself contains variables.
14107 2001-11-12 Akim Demaille <akim@epita.fr>
14109 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14110 Now that M4sh pushes BODY, the comments were output at the end of
14111 the test suites.
14113 2001-11-08 Akim Demaille <akim@epita.fr>
14115 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14116 that we can trace macros from aclocal.m4.
14117 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14118 obsoleted, and redirect to the former anyway.
14119 Reported by Ralf Corsepius.
14121 2001-11-08 Akim Demaille <akim@epita.fr>
14123 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14124 processed only if present.
14125 * tests/torture.at (Configuring subdirectories): Use autoreconf
14126 instead of successive calls to autoconf.
14127 Add a nonexistent subdirectory to exercise the patch above.
14128 Reported by Ralf Corsepius.
14130 2001-11-08 Kevin Ryde <user42@zip.com.au>
14132 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14133 doesn't accept .S files.
14135 2001-11-07 Akim Demaille <akim@epita.fr>
14137 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14138 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14139 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14140 * bin/autom4te.in (warn_forbidden): New.
14141 (handle_output): Use it.
14142 Read m4_pattern_forbid with messages.
14144 2001-11-05 Akim Demaille <akim@epita.fr>
14146 * bin/autom4te.in (--normalize): Remove.
14147 * lib/autom4te.in: Adjust.
14149 2001-11-05 Akim Demaille <akim@epita.fr>
14151 * tests/Makefile.am (testsuite): Rename this target as...
14152 ($(TESTSUITE)): this.
14153 From Nicolas Joly.
14155 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14157 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14158 the --prefix option, also remove it's argument.
14160 2001-11-05 Akim Demaille <akim@epita.fr>
14162 * doc/autoconf.texi (testsuite Invocation): Update.
14163 (Writing testsuite.at): Update.
14165 2001-11-03 Akim Demaille <akim@epita.fr>
14167 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14169 2001-11-03 Akim Demaille <akim@epita.fr>
14171 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14172 (&file_name_is_absolute): New, wrappers around routines from
14173 File::Spec.
14174 Use and export them.
14175 (&find_configure_ac): Optionally take a directory where to look at.
14176 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14177 the arguments.
14178 Default @ARGV to `.', not find_configure_ac.
14179 (&autoreconf): Argument is a directory.
14180 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14181 * doc/autoconf.texi (autoreconf Invocation): Update.
14183 2001-11-03 Akim Demaille <akim@epita.fr>
14185 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14186 (@export_forward_subs): New.
14187 Add basename, dirname, and fileparse.
14188 (@EXPORT): Adjust.
14189 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14190 Don't look for aclocal flags if we already know aclocal is not
14191 used.
14192 Move aclocal.m4t only if it exists.
14193 Reported by Ezra Peisach.
14195 2001-11-03 Akim Demaille <akim@epita.fr>
14197 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14198 passed on command line, defaulting to ./configure.ac if present.
14199 (&maybe_autoreconf, File::Find): Remove, unused.
14200 (&autoreconf): If autoconf is not used, don't try to trace.
14202 2001-11-02 Akim Demaille <akim@epita.fr>
14204 * configure.ac: Bump to 2.52g.
14206 2001-11-02 Akim Demaille <akim@epita.fr>
14208 Version 2.52f.
14210 2001-11-02 Akim Demaille <akim@epita.fr>
14212 * config/config.guess, config/config.sub, doc/standards.texi:
14213 * config/lispdir.m4: Update from masters.
14214 * configure.ac: Bump to 2.52f.
14216 2001-11-02 Akim Demaille <akim@epita.fr>
14218 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14219 Don't run aclocal when aclocal.m4 is not from aclocal.
14220 From Ezra Peisach.
14221 Don't run libtoolize and gettextize if --install is not given.
14223 2001-11-01 Paul Eggert <eggert@twinsun.com>
14225 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14226 be invoked before _AS_LINENO_PREPARE.
14227 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14228 than character ranges.
14230 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14231 invoking AS_BASENAME. Set the locale variables to 'C' if
14232 possible, as POSIX requires this to get the traditional
14233 behavior.
14234 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14236 2001-10-31 Paul Eggert <eggert@twinsun.com>
14238 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14239 with {}, as that triggers a bug in Bash 2.05.
14241 (_AS_LINENO_PREPARE): Use Sed rather than
14242 Awk. Fix the sed prepass to work even if there are multiple
14243 instances of $LINENO on the same line. Do not substitute for
14244 other variables like $LINENOT. Do not check file dates; such a
14245 check is unreliable on sufficiently fast machines, and removing
14246 the check makes the code simpler and more reliable. Check for
14247 output and chmod failures.
14249 * doc/autoconf.texi (Special Shell Variables): Document
14250 the above.
14252 2001-10-31 Akim Demaille <akim@epita.fr>
14254 * tests/Makefile.am (atconfig): Remove this target, Automake
14255 handles it now.
14257 2001-10-31 Akim Demaille <akim@epita.fr>
14259 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14260 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14261 provided, while it is optional.
14262 * configure.ac: Adjust.
14264 2001-10-26 Paul Eggert <eggert@twinsun.com>
14266 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14267 lib/Autom4te/Struct.pm:
14268 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14269 with 5.005_02.
14271 * doc/autoconf.texi (Special Shell Variables): Document some
14272 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14274 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14275 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14276 eval $LINENO is not portable in practice.
14278 2001-10-24 Akim Demaille <akim@epita.fr>
14280 * lib/Autom4te/General.pm (backname): New.
14282 2001-10-24 Akim Demaille <akim@epita.fr>
14284 * m4/: Remove, merged into...
14285 * config/: here.
14287 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14289 * doc/autoconf.texi (Shellology): Mention the problems with bash
14290 2.05's use of ANSI quoting in its `set' builtin.
14292 2001-10-22 Paul Eggert <eggert@twinsun.com>
14294 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14295 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14296 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14297 POSIX decided to standardize on the int flavor of strerror_r.
14298 Always do char* test, as there's no reason not to.
14299 Assign to a char* var, to catch strerror_r that returns int*.
14301 * doc/autoconf.texi (Particular Functions):
14302 Document the above changes. Also, document the fact that
14303 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14305 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14307 2001-10-20 Akim Demaille <akim@epita.fr>
14309 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

14760 (via m4_require). Cosmetic only.
14761 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14762 * lib/autoconf/programs.m4: Replace all the occurrences of
14763 `__oline__' with `$LINENO'.
14764 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
14766 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14768 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14769 character (u: -> ue) in a code comment.
14770 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14771 it works.
14773 2001-09-21 Akim Demaille <akim@epita.fr>
14775 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14776 Suggested by Jim Meyering.
14778 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14780 * lib/autoconf/programs.m4: Use extensions listed in
14781 $ac_executable_extensions when looking for programs.
14783 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14785 * lib/autoconf/general.m4: Fix a small Englisho.
14786 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14787 setting up ac_dir_suffix and ac_top_builddir.
14788 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14790 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14792 * doc/autoconf.texi (File System Conventions): Clarify the use of
14793 PATH_SEPARATOR.
14794 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14795 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14796 be used instead of ':'.
14797 * lib/autotest/general.m4: Replace occurrences of ':' in
14798 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14800 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14802 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14803 arguments. Fixed a typo.
14805 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14807 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14808 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14810 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14812 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14813 * bin/autoupdate.in: Ditto.
14814 * bin/autoheader.in: Reworded a few comments.
14815 * bin/autoconf.in: Reworded help text for a few options.
14816 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14817 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14819 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14821 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14822 already have $file). Set output files to binary mode (helps avoid
14823 CR issues on DOSish systems).
14825 2001-09-19 Akim Demaille <akim@epita.fr>
14827 * lib/autotest/general.m4: Englishoes.
14828 From Tim Van Holder and Alexey Mahotkin.
14830 2001-09-18 Paul Eggert <eggert@twinsun.com>
14832 * doc/autoconf.texi (Common Shell Constructs): New node,
14833 documenting AS_DIRNAME.
14834 (Limitations of Usual Tools): Refer to it when discussing dirname.
14835 Also, update discussion of POSIX standard to reflect latest draft.
14837 * lib/autoconf/c.m4:
14838 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14840 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14841 Do not pass a first argument with leading '-'
14842 to expr, by parenthesizing initial integers that might be negative.
14844 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14845 now merely checks whether it is an error to pass an argument
14846 to getpgrp.
14848 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14849 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14850 whether it is a (compile-time) error to pass an argument to
14851 getpgrp. This simpler test supports the revised documentation,
14852 and is all that AC_FUNC_GETPGRP's users really need.
14854 2001-09-18 Akim Demaille <akim@epita.fr>
14856 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14858 2001-09-18 Akim Demaille <akim@epita.fr>
14860 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14861 `{}'.
14862 * lib/autotest/general.m4 (AT_INIT): Adjust.
14864 2001-09-18 Paul Wagland <paul@wagland.net>
14866 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14867 correctly.
14868 Add test for AS_BASENAME.
14869 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14870 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14871 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14872 * tests/base.at: Fixed the expected responses. The old ones were
14873 one line out...
14874 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14875 the documentation claims it should (and how it behaved in 2.13).
14877 2001-09-18 Akim Demaille <akim@epita.fr>
14879 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14880 the AC_CONFIG_COMMANDS invocation.
14881 This also solves the name clash problems.
14882 Don't set the package's ID.
14883 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14884 No longer to be shipped.
14885 (version.in): Remove.
14886 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14887 * lib/autoconf/status.m4: Adjust.
14888 Use `m4_PACKAGE_STRING'.
14889 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14890 the only optional argument is the name of the test suite.
14891 Expect `package.m4' to define the package signature.
14892 * lib/autom4te.in (Autotest): Add `package.m4?'.
14893 * tests/Makefile.am (package.m4): New.
14894 * tests/suite.at: ifnames is a victim.
14896 2001-09-18 Akim Demaille <akim@epita.fr>
14898 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14899 AC_LIBSOURCE, AC_CONFIG_FILES.
14900 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14901 program version string doesn't match the package's.
14902 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14903 after `(cached)'.
14905 2001-09-17 Paul Eggert <eggert@twinsun.com>
14907 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14908 Allow expression to return any value that can fit into unsigned long
14909 (not int, as before). Check for output errors.
14911 2001-09-17 Bruno Haible <haible@ilog.fr>
14913 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14914 Always include <stdio.h> and <stdlib.h>. Evaluate
14915 the expression in an extra function before these includes. Call
14916 fprintf "%d" only after ensuring the argument is of type 'int'.
14917 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14919 2001-09-17 Paul Eggert <eggert@twinsun.com>
14921 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14922 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14923 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14924 when they don't exist.
14926 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14927 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14928 need it.
14930 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14931 version with the version used by fileutils 4.1, except use
14932 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14933 we don't need it.
14935 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14937 2001-09-13 Akim Demaille <akim@epita.fr>
14939 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14940 _first_.
14941 Reported by Gerrit P. Haase.
14943 2001-09-13 Akim Demaille <akim@epita.fr>
14945 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

14952 Use it.

14961 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14962 Likewise.

14965 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14966 AT_tests_all for consistency.
14967 Set at_victims.
14968 (AT_VICTIMS): Similar to AT_KEYWORDS.
14969 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14971 2001-09-13 Akim Demaille <akim@epita.fr>
14973 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14975 2001-09-13 Akim Demaille <akim@epita.fr>
14977 * lib/autotest/general.m4 (AT_INIT): Create and remove
14978 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14979 test suites can cohabit.
14981 2001-09-13 Akim Demaille <akim@epita.fr>
14983 * tests/mktests.sh: Don't output banners for empty test files.
14985 2001-09-13 Akim Demaille <akim@epita.fr>
14987 Test suites can be run independently of configure.

15035 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

15068 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
15069 in addition, it introduces useless differences in logs.
15070 (AT_INIT): Let atconfig and atlocal be both optional.
15071 Adjust PATH computation.
15072 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

15089 2001-09-05 Akim Demaille <akim@epita.fr>

15092 the maintainer is dumb enough to do that...
15094 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15095 excellence in M4 quotation: consider `__file__' is active.
15097 And BTW, when invoking m4, pass the --include in the right order:

15128 New, extracted from main.
15129 Use IO::File wherever possible.
15130 (input.m4): Be constant, use -I instead of hard coding $tmp.

15132 Don't invoke `_au_disable', since ac was not loaded, but just
15133 `unm4.m4'.
15135 2001-08-31 Akim Demaille <akim@epita.fr>
15137 Version 2.52d.

15160 2001-08-31 Akim Demaille <akim@epita.fr>
15162 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
15163 (testsuite Scripts): There is no such thing as `atconfig.in'.

15166 2001-08-31 Akim Demaille <akim@epita.fr>
15168 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

15176 2001-08-31 Akim Demaille <akim@epita.fr>
15178 * man/Makefile.am (.x.1): We really have to pass
15179 autom4te_perllibdir.
15181 2001-08-31 Akim Demaille <akim@epita.fr>
15183 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
15184 debug scripts, in particular passing explicitly listed tests to
15185 run is stupid.
15187 2001-08-31 Akim Demaille <akim@epita.fr>
15189 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
15190 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15191 Use directly autom4te, not autoconf.

15215 `print $out' doesn't print `$_' but `$out'.
15216 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
15217 (autoheader): Pass --force since the test suite goes too fast for
15218 the time stamps.
15219 Adjust to the new autoheader messages.
15221 2001-08-31 Akim Demaille <akim@epita.fr>
15223 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
15224 Check the completeness of the #template.
15225 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
15226 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
15227 invocation.
15229 2001-08-31 Akim Demaille <akim@epita.fr>
15231 * lib/Autom4te/General.pm (&find_file, &update_file): New.
15232 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15233 Drop AC_MACRODIR dead for real.
15234 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15235 `autoheader: `config.hin' is created'.
15236 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15238 2001-08-31 Akim Demaille <akim@epita.fr>
15240 * bin/autoheader.in: Rewrite in Perl.
15241 * tests/autoheader: Adjust.
15243 2001-08-31 Akim Demaille <akim@epita.fr>
15245 * bin/autoconf.in (--include, -I): New option.
15246 Map --localdir, --autoconf-dir onto it.
15247 Forward autom4te's options instead of interpreting them.
15248 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15249 There is no such envvar since the inception of autom4te.cfg.
15250 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15251 * bin/autoupdate.in: Adjust, and perform more control.
15252 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15253 * tests/autoconf: Dittowise.
15255 2001-08-31 Akim Demaille <akim@epita.fr>
15257 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15258 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15259 optionally `FILE'.
15260 Use -e, not -f, since /dev/null for instance is OK.
15261 (&parse_args): Adjust.
15262 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15264 2001-08-31 Akim Demaille <akim@epita.fr>
15266 * configure.ac: Also find tested executables in bin.
15267 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
15268 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
15269 installed peer executables, only PATH is allowed to resolve it.
15270 Pass `autoconf_dir' via options, not via invisible envvars.
15271 * lib/Autom4te/General.pm (&find_peer): Remove.
15272 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15273 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15274 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15275 find the executables for it.
15276 * tests/Makefile.am: Major cleanup. Too lazy to document...
15277 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15278 We only need PERL.
15279 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15280 indeed related to running the test suite, while passing
15281 --autoconf-dir and others is related to running non installed
15282 Autoconf executables. So don't do that, leave it to...
15283 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15284 * tests/autoscan: New.
15285 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15286 refer to library files: rely on --language.
15288 2001-08-29 Akim Demaille <akim@epita.fr>
15290 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
15291 s/--set/--language/.
15293 2001-08-29 Akim Demaille <akim@epita.fr>
15295 * doc/autoconf.texi: Strip the @nodes.
15296 Suggested by Paul Eggert.
15297 (Initializing configure): Typo.
15299 2001-08-29 Akim Demaille <akim@epita.fr>
15301 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15302 Suggested by Paul Eggert.
15304 2001-08-29 Akim Demaille <akim@epita.fr>
15306 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15307 download in a tmp dir.
15309 2001-08-29 Akim Demaille <akim@epita.fr>
15311 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15312 case insensitive OSes out there :(

15322 (&parse_args): Support --mode, --set, and --melt.
15323 * bin/autoconf.in: Simplify and adjust.
15324 * tests/Makefile.am (AUTOMAKE): Use --set.
15325 * tests/atlocal.in: Adjust.
15326 * BUGS: distcheck and check are weak.
15328 2001-08-29 Akim Demaille <akim@epita.fr>
15330 * lib/autotest/general.m4: Use
15331 foo=`(command) 2>/dev/null`
15332 not
15333 foo=`command` 2>/dev/null
15334 (at-devnull): Rename as...
15335 (AT-devnull): this.
15336 (--clean): Remove AT-* files too.
15337 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15338 Reported by Nicolas Joly.

15353 (AT_INIT): Check for the `times' builtin before using it.
15354 Support test ranges as arguments to the testsuite.
15355 Have -e imply -d as the help text suggested.
15357 2001-08-27 Akim Demaille <akim@epita.fr>
15359 * Makefile.maint: Formatting changes.
15360 (do-po-update, po-update, cvs-update, update): New targets.

15372 * lib/autotest/general.m4 (AT_INIT): Log the command line.
15373 Support `VAR=VAL' as arguments.

15379 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
15380 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
15381 first the build dirs, then the src dirs.

15393 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
15394 `ac_top_builddir' to mimic Automake's vocabulary, which much more
15395 readable.
15396 Adjust callers.
15397 * doc/autoconf.texi (Configuration Actions): Document the vars
15398 available in commands.
15399 Emphasize the risks of collisions in init-cmds.

15430 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15431 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15432 -> ac_dir).
15433 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15434 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

15462 (AMTAR): Help automake define it.

15464 needed, 1.5 can have a macro and a target with the same name.
15465 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15466 * m4/strip.m4: New.

15481 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15482 the name of the directory they're in, instead of the filename,
15483 since version.m4 is now in m4sugar, but m4_acversion must not be
15484 classified as an Autoconf macro.
15485 ($input_m4): Don't qualify the path to m4sugar.
15486 Rather, pass autoconf_dir to m4.
15487 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15488 * tests/suite.at: Require 2.52c.
15490 2001-08-27 Akim Demaille <akim@epita.fr>

15502 of config.log on traps.

15504 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15505 for config.status'.
15506 Open the log as soon as possible.
15507 Use the same log introduction as configure's.
15509 2001-08-22 Paul Eggert <eggert@twinsun.com>
15511 * doc/autoconf.texi (Indices): New node.
15512 Move indices out of the top level menu and into this submenu.
15514 2001-08-22 Akim Demaille <akim@epita.fr>
15516 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
15517 AC_TRY_COMMAND.
15518 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

15561 can be used.
15563 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
15565 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
15566 program with AC_LANG_PROGRAM before feeding it to
15567 AC_COMPILE_IFELSE. Cleanup grep usage.
15569 2001-08-20 Akim Demaille <akim@epita.fr>
15571 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15572 * NEWS, README, README-alpha, TODO, tests/README: This package is
15573 `Autoconf', not `autoconf' (the executable).
15575 2001-08-20 Akim Demaille <akim@epita.fr>
15577 Info readers seem to need `Index' in the index node title :(
15579 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15580 simplified index node names.
15582 2001-08-20 Akim Demaille <akim@epita.fr>
15584 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
15585 arguments are not literals.
15586 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
15587 Specify the output variables, and macros defined.
15589 2001-08-20 Akim Demaille <akim@epita.fr>
15591 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
15592 (Examining Syntax) <AC_TRY_COMPILE>
15593 (Examining Libraries) <AC_TRY_LINK>
15594 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
15595 their arguments.
15596 Reported by Werner Lemberg.
15598 2001-08-20 Akim Demaille <akim@epita.fr>

15613 2001-08-20 Akim Demaille <akim@epita.fr>
15615 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
15616 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
15617 test suite lives.
15618 Create `atconfig' automagically.
15619 Configure atlocal.in if present.
15620 * tests/atconfig.in: Remove.

15624 2001-08-20 Akim Demaille <akim@epita.fr>
15626 Huh!?!?! There are still some user EOF tags used, which prevents
15627 their use in AC_CONFIG_COMMANDS for instance...
15629 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15630 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
15631 `_CSEOF', or `_ATEOF', as appropriate.
15632 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
15633 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

15711 * doc/autoconf.texi: Work around Texinfo buglets.
15712 (Transformation Rules): One example is enough, users are expected
15713 to have their brains on. And BTW, use DESTDIR.
15714 (dvar): New macro. Use it.
15716 2001-08-17 Akim Demaille <akim@epita.fr>
15718 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15758 value.

15766 (cvs-dist): depends upon it.
15768 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15770 * tests/Makefile.am: Use a clean-local rule to remove
15771 autom4te.cache (it's a directory, not a file.
15772 * Makefile.am: Ditto (but maintainer-clean-local).
15774 2001-08-15 Akim Demaille <akim@epita.fr>
15776 * bin/autom4te.in (@m4_warning): New.
15777 (&handle_m4): Use it.
15778 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15779 warnings are issued at each run.
15780 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15781 is in the src tree.
15783 2001-08-15 Akim Demaille <akim@epita.fr>
15785 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15786 don't waste time running `autoupdate --version' works.
15787 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15789 2001-08-13 Akim Demaille <akim@epita.fr>
15791 * doc/autoconf.texi (ma): Rename this index as...

15848 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15850 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15851 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15852 * doc/autoconf.texi (C Compiler Characteristics): Update
15853 documentation for AC_C_BIGENDIAN.
15855 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15857 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15858 magic values from an object file when cross-compiling.
15859 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15861 2001-08-10 Akim Demaille <akim@epita.fr>
15863 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15864 effects.
15865 Suggested by Russ Allbery.
15867 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15869 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15870 current $prefix to the sub-configures.
15872 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15874 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15875 extension (needed on BeOS). Reported by Guido van Rossum.
15877 2001-08-09 Akim Demaille <akim@epita.fr>
15879 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15881 2001-08-07 Akim Demaille <akim@epita.fr>
15883 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15884 removed.
15885 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15886 No need to remove the files before and after the each test, before
15887 each test and at the end of the suite is enough.
15888 Display only the children `times', not the shell's.
15889 If the test failed or was skipped, at-times is not available.
15891 2001-08-07 Akim Demaille <akim@epita.fr>
15893 Always produce testsuite.log, including when there are no
15894 failures. This helps getting information on skipped tests, and
15895 duration of the tests. Err, implement the latter btw.
15897 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15898 Dump information on the first run of each test.
15899 (AT_CLEANUP): Create `at-times' containing the duration of the
15900 test group.
15902 2001-08-07 Akim Demaille <akim@epita.fr>
15904 The use of `dumpstat' revealed that `len' was used although it
15905 should not. m4_text_wrap was using it, but in the Autoconf world
15906 where it is legal. Hence (i) test M4sh in its own world, not
15907 Autoconf's, and (ii), ahem, fix the bug :)
15909 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15910 does not like `' instead of [].
15911 (AT_INIT): Forbid `^_?AT_'.
15912 And don't output such tokens.
15913 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15914 `script.as', and `autom4te.cache'.
15915 Remove `empty' and `macro' which are no longer used.
15916 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15917 * tests/m4sugar.at: Use it.
15918 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15920 2001-08-07 Akim Demaille <akim@epita.fr>
15922 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15924 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15926 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15928 2001-08-04 Akim Demaille <akim@epita.fr>
15930 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15931 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15932 AC_TRY_LINK.
15933 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15934 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15935 (AC_F77_MAIN): Likewise.
15937 2001-08-04 Akim Demaille <akim@epita.fr>
15939 Don't rely on M4sugar outputting the patterns in files, since we
15940 might process the output _without_ running m4, hence without these
15941 files.
15943 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15944 * bin/autom4te.in (@Request::includes): Remove, unused.
15945 (@Request::source): Rename as...
15946 (@Request::input): this.
15947 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15948 (&handle_output): Fetch the patterns from the traces.
15949 `$forbidden' and `$allowed' are constant: use m//o.
15950 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15951 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15953 2001-08-04 Akim Demaille <akim@epita.fr>
15955 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15956 autoconf', i.e., in addition to caching traces, cache the output.
15958 * bin/autom4te.in (Request::cache): Rename as...
15959 (Request::id): this.
15960 ($cache, $icache, $tcache, $ocache): New.
15961 (&handle_m4): Save M4 output in the cache instead of $tmp.
15962 (&handle_output): Adjust.
15963 (&up_to_date_p): Check that the output cache is up to date too.
15964 (top level): Run `&handle_m4' iff force or the cache is invalid.
15965 Run `&handle_output' if the output cache is more recent.
15967 2001-08-04 Akim Demaille <akim@epita.fr>
15969 * bin/autom4te.in ($force): New.
15970 (&parse_args, &print_usage): -f, --force is a new option.
15971 (&handle_output): CPP directives might have spaces after `#'.
15972 (&parse_args): The first file only can be frozen.
15974 2001-08-04 Akim Demaille <akim@epita.fr>
15976 Don't let autom4te compute the `include' traces several times:
15977 first check that the trace cache file is up to date, and then
15978 compare its timestamp with that of the output.
15980 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15981 the preamble. Don't require 5.005 as Autom4te::General does it,
15982 and better yet (use `use', not `require'!).
15983 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15984 Class::Struct as Autom4te::Struct.
15985 * lib/Autom4te/General.pm (File::stat): Use it.
15986 (&mtime): New, export it.
15987 * bin/autom4te.in: Use it.
15988 Declare `$req' is invalid if it is outdated.
15989 Don't declare it valid before saving it if something went wrong.
15991 2001-08-04 Akim Demaille <akim@epita.fr>
15993 Autom4te shall not encode Autoconf data, and preselecting traces
15994 must be proposed to the users.
15996 * bin/autom4te.in (@required_trace): Remove.
15997 (@preselect): New.
15998 (&parse_args, &print_usage): -p, --preselect is a new option.
15999 (&up_to_date_p): Adjust.
16000 * bin/autoconf.in: Preselect some Autoconf macros.
16002 2001-08-04 Akim Demaille <akim@epita.fr>
16004 * tests/tools.at (autoconf --trace: user macros): Check traces on
16005 macros invoked without arguments, and macros invoked with multiple
16006 lines arguments.
16008 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
16010 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
16011 arguments.
16013 2001-08-03 Akim Demaille <akim@epita.fr>
16015 * bin/autoconf.in ($@): Work around the usual sh bug.
16016 From Nicolas Joly.
16018 2001-08-03 Akim Demaille <akim@epita.fr>
16020 Clean up the handling of the M4 builtins tracing exception.
16022 * bin/autom4te.in (Request::request): Don't complete M4 builtins
16023 trace requests.

16027 (&parse_args): Complete the trace requests with alternate names.
16028 (&handle_traces): Hence no longer do it here.
16029 (&trace_requests): Remove, unused.
16031 2001-08-03 Akim Demaille <akim@epita.fr>
16033 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16034 m4_if, and m4_wrap.
16036 2001-08-03 Akim Demaille <akim@epita.fr>
16038 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16039 (m4_divert_pop): Dump the whole diversion stack when a diversion
16040 mismatch happens.
16041 * bin/autom4te.in (&handle_output): Remember of the first
16042 occurrence of a possibly undefined macro, not the last.
16043 Complain about the possibly undefined macros in the same order as
16044 the appear in the output.
16045 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16046 * tests/tools.at (autoconf: forbidden tokens, basic)
16047 (autoconf: forbidden tokens, exceptions): No longer sort
16048 autoconf's stderr, as it is now deterministic.
16049 Check that `dnl' is caught.
16051 2001-08-01 Akim Demaille <akim@epita.fr>
16053 * configure.ac: Bump to 2.52c.

16068 `die'.
16069 (&END): New.
16070 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
16071 `END', as `Autom4te::General::END' will be triggered.
16072 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
16073 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

16465 compiler, not the preprocessor.

16508 cross-language link tests can be performed successfully.
16509 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
16510 after $LIBS, for consistency; this should be the general rule since

16517 at-stdout and at-stderr instead of removing the newline
16518 from the echo output, which is not guaranteed to work.
16520 2001-06-28 Jens Petersen <petersen@redhat.com>
16522 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
