There are many small bug fixes, and all the executables have been revamp around autom4te. Autotest is also getting mature, but still lacks some decent documentation. This is the main focus before the release, the code should not change significantly.
Please, use it, test it, torture, like it. ftp://alpha.gnu.org/gnu/autoconf/autoconf-2.52f.tar.gz (937 kB) ftp://alpha.gnu.org/gnu/autoconf/autoconf-2.52f.tar.bz2 (718 kB) And here are xdelta-style diffs ftp://alpha.gnu.org/gnu/autoconf/autoconf-2.52d-2.52f.xdelta (66 kB) Here are the MD5 and SHA1 signatures for the compressed tar files: c24dab39ac05c0ebf75d67fb779e4787 autoconf-2.52f.tar.gz 699858608615777862bdadfa7dbe0207 autoconf-2.52f.tar.bz2 c1b54f5dfe75ad4b3ec170e8ece90942fdf38826 autoconf-2.52f.tar.gz 77bc5075bc8f179899b305ec25823b18b75e352f autoconf-2.52f.tar.bz2 NEWS: ** Requirements Perl 5.005_03 or later is required: autom4te is written in Perl and is needed by autoconf. autoheader, autoreconf, ifnames, and autoscan are rewritten in Perl. ** Documentation - AC_INIT Argument requirements, output variables, defined macros. - M4sugar, M4sh, Autotest First sketch. - Double quoting macros AC_TRY_CPP, AC_TRY_COMPILE, AC_TRY_LINK and AC_TRY_RUN. - Licensing The Autoconf manual is now distributed under the terms of the GNU FDL. ** configure - $LINENO Now used instead of hard coded line numbers. This eases the comparison of `configure's, and diminishes the pressure over control version archives. Automatic replacement for shells that don't support this feature. - New output variables @builddir@, @top_builddir@, @srcpath@, @top_srcpath@, @buildpath@, @top_buildpath@. ** Emacs Autoconf and Autotest modes are provided. ** Executables - autom4te New, used by the Autoconf suite to cache and speed up most processing. - --force, -f Supported by autom4te, autoconf and autoheader. - --include, -I Replaces --autoconf-dir and --localdir in autoconf, autoheader, autoupdate, and autoreconf. - autoreconf No longer passes --cygnus, --foreign, --gnits, --gnu, --include-deps: automake options are to be given via AUTOMAKE_OPTIONS. - autoreconf Runs gettextize and libtoolize when appropriate. - autoreconf --m4dir is no longer supported. ** Bug fixes - The top level $prefix is propagated to the AC_CONFIG_SUBDIRS configures. - AC_TRY_RUN Under the user pressure, $? is finally available. Probably a mistake. ** C Macros - AC_C_BIGENDIAN supports the cross-compiling case. - AC_C_BIGENDIAN accepts ACTION-IF-TRUE, ACTION-IF-FALSE, and ACTION-IF-UNKNOWN arguments. All are facultative, and the default for ACTION-IF-TRUE is to define WORDS_BIGENDIAN like AC_C_BIGENDIAN always did. ** Generic macros - AC_CONFIG_COMMANDS, HEADERS, FILES, LINKS. Provide the user with srcdir, ac_srcdir, ac_top_srcdir, ac_builddir, ac_top_builddir, ac_srcpath, ac_top_srcpath, ac_buildpath, ac_top_buildpath. ** Library macros - AC_FUNC_STRERROR_R now sets STRERROR_R_CHAR_P, not HAVE_WORKING_STRERROR_R, because POSIX 1003.1-200x draft 7 says strerror_r returns int, not char *. ChangeLog entries: 2001-11-02 Akim Demaille <[EMAIL PROTECTED]> Version 2.52f. 2001-11-02 Akim Demaille <[EMAIL PROTECTED]> * config/config.guess, config/config.sub, doc/standards.texi: * config/lispdir.m4: Update from masters. * configure.ac: Bump to 2.52f. 2001-11-02 Akim Demaille <[EMAIL PROTECTED]> * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''. Don't run aclocal when aclocal.m4 is not from aclocal. From Ezra Peisach. Don't run libtoolize and gettextize if --install is not given. 2001-11-01 Paul Eggert <[EMAIL PROTECTED]> * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to be invoked before _AS_LINENO_PREPARE. (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather than character ranges. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before invoking AS_BASENAME. Set the locale variables to 'C' if possible, as POSIX requires this to get the traditional behavior. * doc/autoconf.texi (Special Shell Variables): Describe the above. 2001-10-31 Paul Eggert <[EMAIL PROTECTED]> * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body with {}, as that triggers a bug in Bash 2.05. (_AS_LINENO_PREPARE): Use Sed rather than Awk. Fix the sed prepass to work even if there are multiple instances of $LINENO on the same line. Do not substitute for other variables like $LINENOT. Do not check file dates; such a check is unreliable on sufficiently fast machines, and removing the check makes the code simpler and more reliable. Check for output and chmod failures. * doc/autoconf.texi (Special Shell Variables): Document the above. 2001-10-31 Akim Demaille <[EMAIL PROTECTED]> * tests/Makefile.am (atconfig): Remove this target, Automake handles it now. 2001-10-31 Akim Demaille <[EMAIL PROTECTED]> * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be provided, while it is optional. * configure.ac: Adjust. 2001-10-26 Paul Eggert <[EMAIL PROTECTED]> * NEWS, README, configure.ac, lib/Autom4te/General.pm, lib/Autom4te/Struct.pm: Require Perl 5.005_03 instead of just 5.005, as some tests fail with 5.005_02. * doc/autoconf.texi (Special Shell Variables): Document some more LINENO gotchas, particularly with respect to the Awk+Sed hack. * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro. (_AS_LINENO_PREPARE): Use it instead of shell eval, since eval $LINENO is not portable in practice. 2001-10-24 Akim Demaille <[EMAIL PROTECTED]> * lib/Autom4te/General.pm (backname): New. 2001-10-24 Akim Demaille <[EMAIL PROTECTED]> * m4/: Remove, merged into... * config/: here. 2001-10-23 Tim Van Holder <[EMAIL PROTECTED]> * doc/autoconf.texi (Shellology): Mention the problems with bash 2.05's use of ANSI quoting in its `set' builtin. 2001-10-22 Paul Eggert <[EMAIL PROTECTED]> * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R): Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p, and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since POSIX decided to standardize on the int flavor of strerror_r. Always do char* test, as there's no reason not to. Assign to a char* var, to catch strerror_r that returns int*. * doc/autoconf.texi (Particular Functions): Document the above changes. Also, document the fact that AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R. * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P. 2001-10-20 Akim Demaille <[EMAIL PROTECTED]> * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of the executable was missing from the log. 2001-10-20 Akim Demaille <[EMAIL PROTECTED]> * lib/Autom4te/General.pm (&update_file): If destination is unchanged, remove the source. (&up_to_date_p): Don't be verbose, be debug. * bin/autoreconf.in: No longer support --m4dir. (&autoreconf): Display the full path of the configure.ac we are studying. Trace it only once. Be sure to honor --force with gettextize. Always run aclocal. * doc/autoconf.texi: Adjust. 2001-10-20 Akim Demaille <[EMAIL PROTECTED]> * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX): Remove, dead. * bin/autoreconf.in (&autoreconf): Do not run gettextize when `intl' is already present, as it refuses unless --force. (&parse_args): Use -I, --include instead of the old Autoconf options. ($localdir, $autoconf_dir): Remove. (@include): New. (&maybe_autoreconf): New, to preserve $_ for File::Find. 2001-10-19 Jens Petersen <[EMAIL PROTECTED]> * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk. * doc/autoconf.texi (Particular Programs): Likewise. 2001-10-19 Akim Demaille <[EMAIL PROTECTED]> * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated file in @configure_input@. Don't mention `automatically' in addition to `generated'. * tests/torture.at (#define header templates): Adjust. 2001-10-19 Akim Demaille <[EMAIL PROTECTED]> * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a comment, explain how to install automatic mode selection. From Russ Allbery. 2001-10-19 Ezra Peisach <[EMAIL PROTECTED]> * bin/autoreconf.in (autoreconf): Display the path to the configure.ac being studied. 2001-10-18 Paul Eggert <[EMAIL PROTECTED]> * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned long, to work around a bug in the HP C compiler version HP92453-01 B.11.11.23709.GP. * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works. (AS_BASENAME_EXPR): New macro. (AS_BASENAME_SED): Do not assume GNU sed semantics. (AS_BASENAME): Use 'basename' if that works; then try 'expr'; and fall back on 'sed' only if the other two fail. This makes AS_BASENAME act more like AS_DIRNAME. (as_me): Shell-quote the argument of AS_BASENAME, in case $0 contains white space. * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Use AS_DIRNAME, since I think it's now DOS-friendly. * tests/m4sh.at (DIRNAME_TEST): New arg $3. Allow "dirname //FOO" to return either / or //, as POSIX allows either behavior. 2001-10-10 Akim Demaille <[EMAIL PROTECTED]> * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV. From Eric Sharkey. 2001-10-10 Akim Demaille <[EMAIL PROTECTED]> * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not m4_define, since...

(Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should be used instead of ':'. * lib/autotest/general.m4: Replace occurrences of ':' in AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup. 2001-09-20 Tim Van Holder <[EMAIL PROTECTED]> * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as arguments. Fixed a typo. 2001-09-20 Tim Van Holder <[EMAIL PROTECTED]> * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly. 2001-09-20 Tim Van Holder <[EMAIL PROTECTED]> * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'. * bin/autoupdate.in: Ditto. * bin/autoheader.in: Reworded a few comments. * bin/autoconf.in: Reworded help text for a few options. * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in, * bin/autoscan.in, bin/autoupdate.in: Ditto. 2001-09-20 Tim Van Holder <[EMAIL PROTECTED]> * lib/Autom4te/XFile.pm (open): Simplified the error message (we already have $file).

From Tim Van Holder and Alexey Mahotkin. 2001-09-18 Paul Eggert <[EMAIL PROTECTED]> * doc/autoconf.texi (Common Shell Constructs): New node, documenting AS_DIRNAME. (Limitations of Usual Tools): Refer to it when discussing dirname. Also, update discussion of POSIX standard to reflect latest draft. * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN. * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE): Do not pass a first argument with leading '-' to expr, by parenthesizing initial integers that might be negative. * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP now merely checks whether it is an error to pass an argument to getpgrp. * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove. (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check whether it is a (compile-time) error to pass an argument to getpgrp. This simpler test supports the revised documentation, and is all that AC_FUNC_GETPGRP's users really need. 2001-09-18 Akim Demaille <[EMAIL PROTECTED]> * doc/autoconf.texi (Limitations of Make) <$<>: New. 2001-09-18 Akim Demaille <[EMAIL PROTECTED]> * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about `{}'. * lib/autotest/general.m4 (AT_INIT): Adjust. 2001-09-18 Paul Wagland <[EMAIL PROTECTED]> * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///' correctly. Add test for AS_BASENAME. * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous added test. It now correctly handles /1/2/3/, returning '3' not ''. Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME. * tests/base.at: Fixed the expected responses. The old ones were one line out... * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as the documentation claims it should (and how it behaved in 2.13). 2001-09-18 Akim Demaille <[EMAIL PROTECTED]> * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in the AC_CONFIG_COMMANDS invocation. This also solves the name clash problems. Don't set the package's ID. * lib/m4sugar/Makefile.am (version.m4): Revamp. No longer to be shipped. (version.in): Remove. * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4, * lib/autoconf/status.m4: Adjust. Use `m4_PACKAGE_STRING'. * lib/autotest/general.m4 (AT_INIT): N-th signature change: now the only optional argument is the name of the test suite. Expect `package.m4' to define the package signature. * lib/autom4te.in (Autotest): Add `package.m4?'. * tests/Makefile.am (package.m4): New. * tests/suite.at: ifnames is a victim. 2001-09-18 Akim Demaille <[EMAIL PROTECTED]> * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL, AC_LIBSOURCE, AC_CONFIG_FILES. * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested program version string doesn't match the package's. * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space after `(cached)'. 2001-09-17 Paul Eggert <[EMAIL PROTECTED]> * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)): Allow expression to return any value that can fit into unsigned long (not int, as before). Check for output errors. 2001-09-17 Bruno Haible <[EMAIL PROTECTED]> * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)): Always include <stdio.h> and <stdlib.h>. Evaluate the expression in an extra function before these includes. Call fprintf "%d" only after ensuring the argument is of type 'int'. Reported by Wayne Chapeskie <[EMAIL PROTECTED]>. 2001-09-17 Paul Eggert <[EMAIL PROTECTED]> Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4 or CFLAGS=-O5. In that case, the linker has a relaxed view of fatal errors, and AC_CHECK_LIB causes it to include libraries even when they don't exist. * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't need it. * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty version with the version used by fileutils 4.1, except use AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if we don't need it. * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior. 2001-09-13 Akim Demaille <[EMAIL PROTECTED]> * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line _first_.
