Autoconf 2.52g is released

From: Akim Demaille
Subject: Autoconf 2.52g is released
Date: 25 Jan 2002 12:48:15 +0100
User-agent: Gnus/5.0808 (Gnus v5.8.8) XEmacs/21.4 (Common Lisp)

The following message is a courtesy copy of an article
that has been posted to gnu.utils.bug as well.

Of course there are still many things that ought to be done in
Autoconf, nevertheless, there is no point in waiting for the day where
Autoconf will be complete (as by definition, there is always something
wrong for someone).

We aim at releasing 2.53 within the next months.  This is also a call
for people ready to:

- improve the documentation
- upgrade existing specific macros
- import into Autoconf wide spread specific macros

Thanks!   (959 kB)  (735 kB)

And here are xdelta-style diffs   (50 kB)

Here are the MD5 and SHA1 signatures for the compressed tar files:

** 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

  Argument requirements, output variables, defined macros.
- M4sugar, M4sh, Autotest
  First sketch.
- Double quoting macros
- Licensing
  The Autoconf manual is now distributed under the terms of the GNU FDL.

** configure

  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@, @abs_srcdir@, @abs_top_srcdir@, @abs_builddir@,

** 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.
- autoreconf
  Now runs only in the specified directories, defaulting to `.',
  but understands AC_CONFIG_SUBDIRS for dependent directories.
  Before, it used to run on all the `' found in the
  current tree.
  Independent packages are properly updated.

** Bug fixes

- The top level $prefix is propagated to the AC_CONFIG_SUBDIRS configures.
  Under the user pressure, $? is finally available.  Probably a mistake.
- AC_F77_LIBRARY_LDFLAGS now supports the HP/UX f90 compiler.
- Precious variables accumulation
  config.status could stack several copies of the precious variables

** C Macros

- AC_C_BIGENDIAN supports the cross-compiling case.
  ACTION-IF-UNKNOWN arguments.  All are facultative, and the default
  always did.
- AC_C_LONG_DOUBLE now succeeds only if `long double' has more range or
  precision than `double'.

** Generic macros

  It now defines the preprocessor symbols PACKAGE_NAME,

  Provide the user with srcdir, ac_srcdir, ac_top_srcdir, ac_builddir,
  ac_top_builddir, ac_abs_srcdir, ac_abs_top_srcdir, ac_abs_builddir,

  Are much less expensive when using long lists of files.

** Library macros

  because POSIX 1003.1-200x draft 7 says strerror_r returns int, not char *.

- AC_FUNC_STRTOD substitutes POW_LIB.

        Use it.

2001-11-25  Joseph S. Myers  <address@hidden>

        * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,

        * doc/autoconf.texi (Installation Directory Variables): Englishoes
        spotted by Jim Meyering.

2001-11-16  Paul Eggert  <address@hidden>

        This patch implements a `long double' suggestion by Oliver Kiddle.

        * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
        static, to catch errors if the value isn't known at compile-time
        and the compiler supports dynamic arrays.  Change its name from
        `_array_' to `test_array' to avoid potential name clashes.
        (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
        test.  Do not define HAVE_LONG_DOUBLE if `long double' is no
        better than double.  Catch a bug in GCC 2.95.2 x86.
        * doc/autoconf.texi (C Compiler): Document the above.
        * NEWS: Likewise.

2001-11-13  Akim Demaille  <address@hidden>

        * tests/ (LINENO): Protect from autom4te's substitution by
        * tests/ Don't protect dnl, AT_DATA_M4SH does.

2001-11-13  Akim Demaille  <address@hidden>

        * lib/autotest/general.m4 (AT_INIT): After having run the test
        group, go back to the initial directory, not to at_suite_dir.

2001-11-13  Akim Demaille  <address@hidden>

        * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
        (AT_DATA_AUTOCONF):  Also protect @&t@ from autom4te.
        (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
        (AT_CHECK_CONFIGURE): Use absolute paths.
        (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
        The problem is still the old one: there is no means in M4 (that I
        know about) to create a defining macro, because there is no means
        to create `$1' etc., therefore, the defining macro ``swallows''
        all the arguments meant to the defined macro.

2001-11-13  Akim Demaille  <address@hidden>

        * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
        (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
        * tests/aclocal.m4: Remove, as it is no longer used.

2001-11-13  Akim Demaille  <address@hidden>

        * lib/autotest/general.m4: Change `tests?' into `groups?' in
        variable names when referring to a single test group, or to
        `suite' when referring to the whole test suite.
        `at_last_test' is removed: m4 compute at_format itself.
        (at_stdout, at_stder1, at_stderr): New variables.
        (AT_CHECK): Use them.

2001-11-13  Akim Demaille  <address@hidden>

        * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
        in PATH.
        Create `testsuite.dir/003/run' instead of `testsuite.003'.
        Do it as soon as a test fails, don't wait till the end of the test
        Don't remove $as_me.[0-9]*, since these files no longer exist.

2001-11-13  Akim Demaille  <address@hidden>

        * tests/ Use absolute paths, since we are no longer run
        in place.

2001-11-13  Akim Demaille  <address@hidden>

        Now that tests are running in their own private dir, there is no
        need to list the files to remove at the end of tests groups.

        * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
        (AT_data_files, at_data_files): Remove.
        (AT_CLEANUP, AT_DATA): Simplify.
        (AT_INIT): Adjust.
        Remove the group dir if !debug && !failed.
        * tests/atspecific.m4: Adjust.

2001-11-13  Akim Demaille  <address@hidden>

        Start a new layout for Autotest: `testsuite' creates
        `testsuite.dir' in which the at-check-line etc. files are to be
        found, and `testsuite.dir/003' where the test group 3 is run.

        * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
        at_check_line_file, at_format, at_test_normalized, at_group_dir
        are new variables.
        Create the directories.
        Use absolute paths for at- files.
        (AT_CHECK): Adjust.

2001-11-11  Michael Matz  <address@hidden>

        * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
        (m4_car2): New.
        (m4_car): Properly quote arguments.

2001-11-13  Akim Demaille  <address@hidden>

        * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&address@hidden/ to 
        with stricter rules on LIBOBJS.

2001-11-12  Paul Eggert  <address@hidden>

        * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
        * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
        __PROTOTYPES too.

2001-11-12  Akim Demaille  <address@hidden>

        * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.

2001-11-12  Akim Demaille  <address@hidden>

        * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
        * lib/autoconf/functions.m4, lib/autoconf/general.m4,
        * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
        * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
        * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
        specify to what the macro should be defined (typically to 1).

2001-11-12  Akim Demaille  <address@hidden>

        * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
        From Jim Meyering.

2001-11-12  Akim Demaille  <address@hidden>

        * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
        AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND.  This validates the
        definition used by Automake where LEX is +/- "${missing} lex" and
        `missing' itself contains variables.

2001-11-12  Akim Demaille  <address@hidden>

        * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
        Now that M4sh pushes BODY, the comments were output at the end of
        the test suites.

2001-11-08  Akim Demaille  <address@hidden>

        * bin/ (&autoreconf): Run aclocal before tracing, so
        that we can trace macros from aclocal.m4.
        Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
        obsoleted, and redirect to the former anyway.
        Reported by Ralf Corsepius.

2001-11-08  Akim Demaille  <address@hidden>

        * bin/ (&autoreconf): AC_CONFIG_SUBIDRS are to be
        processed only if present.
        * tests/ (Configuring subdirectories): Use autoreconf
        instead of successive calls to autoconf.
        Add a nonexistent subdirectory to exercise the patch above.
        Reported by Ralf Corsepius.

2001-11-08  Kevin Ryde  <address@hidden>

        * autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
        doesn't accept .S files.

        * bin/ (warn_forbidden): New.
        (handle_output): Use it.
        Read m4_pattern_forbid with messages.

        ($(TESTSUITE)): this.
        From Nicolas Joly.

2001-11-05  Alexandre Duret-Lutz  <address@hidden>

        * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
        the --prefix option, also remove it's argument.

2001-11-05  Akim Demaille  <address@hidden>

        * doc/autoconf.texi (testsuite Invocation): Update.
        (Writing Update.

2001-11-03  Akim Demaille  <address@hidden>

        * doc/autoconf.texi: s/@code/@command/ where appropriate.

2001-11-03  Akim Demaille  <address@hidden>

        * lib/Autom4te/ (&catfile, &canonfile)
        (&file_name_is_absolute): New, wrappers around routines from
        Use and export them.
        (&find_configure_ac): Optionally take a directory where to look at.
        * bin/ (&parse_args): Trim the part of
        the arguments.
