GNU Automake 1.12.3 released

From: Stefano Lattarini
Subject: GNU Automake 1.12.3 released
Date: Tue, 14 Aug 2012 13:12:48 +0200

We are pleased to announce the Automake 1.12.3 maintenance release.

This release:

  - reworks and reshuffles the Automake testsuite a bit; fixing some
    weaknesses and spurious failures in the process, but also, likely,
    introducing new ones;

  - introduces initial support for automatic dependency tracking with
    the Portland Group C/C++ compilers (thanks to Dave Goodell and
    Jeff A. Daily);

  - fixes several long-standing bugs and limitations in the 'ylwrap'
    script (thanks to Akim Demaille); among the other things, the
    long-standing PR/491 and automake bug#7648 are now fixed.

See below for the detailed list of changes since Automake 1.12, as
summarized by the NEWS file.

Thanks to everyone who has reported problems, contributed patches,
and helped testing Automake!


New in 1.12.3:

* WARNING: Future backward-incompatibilities!

  - Future versions of Automake will likely drop support for the
    long-deprecated '' name for the Autoconf input file.
    You are advised to use the recommended name '' instead.

  - The long-obsolete (since automake 1.10) AM_PROG_MKDIR m4 macro will
    be removed in Automake 1.13.  The $(mkdir_p) make variable and the
    @mkdir_p@ substitution will still remain available (as aliases of
    $(MKDIR_P)) for the moment, for better backward compatibility.

  - Autoconf 2.65 or later will be required by the next major Automake
    version (1.13).  Until now, Automake has required Autoconf version
    2.62 or later.

  - Starting from the next major Automake version (1.13), the rules
    to build pdf, ps and dvi output from Texinfo input will use the
    '--build-dir' option by default.  Since such an option was only
    introduced in Texinfo 4.9, this means that Makefiles generated by
    future Automake versions will require at least that version of

  - Starting from the next major Automake version (1.13), the parallel
    testsuite harness (previously only enabled by the 'parallel-tests'
    option) will become the default one; the older serial testsuite
    harness will still be available through the use of the 'serial-tests'

  - The following long-obsolete m4 macros will be removed in the
    next major Automake version (1.13):

      AM_PROG_CC_STDC:    superseded by AC_PROG_CC since October 2002
      fp_PROG_CC_STDC:    broken alias for AM_PROG_CC_STDC
      fp_WITH_DMALLOC:    old alias for AM_WITH_DMALLOC
      AM_CONFIG_HEADER:   superseded by AC_CONFIG_HEADERS since July 2002
      ud_PATH_LISPDIR:    old alias for AM_PATH_LISPDIR
      ud_GNU_GETTEXT:     old alias for AM_GNU_GETTEXT
      gm_PROG_LIBTOOL:    old alias for AC_PROG_LIBTOOL
      fp_C_PROTOTYPES:    old alias for AM_C_PROTOTYPES (which was part
                          of the now-removed automatic de-ANSI-fication
                          support of Automake)

  - All the "old alias" macros in 'm4/obsolete.m4' will be removed in
    the next major Automake version (1.13).

  - Support for the two- and three-arguments invocation forms of the
    AM_INIT_AUTOMAKE macro is deprecated, and will be removed in the
    next major Automake version (1.13).

  - The '--acdir' option of aclocal is deprecated, and will probably
    be removed in the next major Automake release (1.13).  You should
    use the options '--automake-acdir' and '--system-acdir' instead
    (which have been introduced in Automake 1.11.2).

  - The exact order in which the directories in the aclocal macro
    search path are looked up is probably going to be changed in the
    next Automake release (1.13).

  - The 'missing' script will not try anymore to update the timestamp
    of out-of-date files that require a maintainer-specific tool to be
    remade, in case the user lacks such a tool (or has a too-old version
    of it).  In fact, starting from Automake 1.13, all it'll do will be
    giving more useful warnings than a bare "command not found" from a
    make recipe would.

* Miscellaneous changes:

  - The '.m4' files provided by Automake does not define serial numbers
    anymore.  This should cause no difference in the behaviour of aclocal

  - Some testsuite weaknesses and spurious failures have been fixed.

  - There is initial support for automatic dependency tracking with the
    Portland Group C/C++ compilers, thanks to the new new depmode 'pgcc'.

Bugs fixed in 1.12.3:

* Long-standing bugs:

  - Instead of renaming only self-references of files (typically for
    #lines), ylwrap now also renames references to the other generated
    files.  This fixes support for GLR and C++ parsers from Bison (PR
    automake/491 and automake bug#7648): 'parser.c' now properly
    #includes 'parser.h' instead of ''.

  - Generated files unknown to ylwrap are now preserved.  This fixes
    C++ support for Bison (automake bug#7648): location.hh and the
    like are no longer discarded.
