Update to 1.14:

* WARNING: New versioning scheme for Automake.

  - Beginning with the release 1.13.2, Automake has started to use a
    more rational versioning scheme, that should allow users to know
    which kind of changes can be expected from a new version, based
    on its version number.

    + Micro releases (e.g., 1.13.3, 2.0.1, 3.2.8) introduce only bug
      and regression fixes and documentation updates; they should not
      introduce new features, nor any backward-incompatibility (any
      such incompatibility would be considered a bug, to be fixed with
      a further micro release).

    + Minor releases (e.g., 1.14, 2.1) can introduce new backward
      compatible features; the only backward-incompatibilities allowed
      in such a release are new *non-fatal* deprecations and warnings,
      and possibly fixes for old or non-trivial bugs (or even inefficient
      behaviours) that could unfortunately have been seen and used by
      some as "corner case features".  Possible disruptions caused by
      this kind of fixes should hopefully be quite rare, and their
      effects limited in scope.

    + Major versions (now expected to be released every 18 or 24 months,
      and not more often) can introduce new big features (possibly with
      rough edges and not-fully-stabilized APIs), removal of deprecated
      features, backward-incompatible changes of behaviour, and possibly
      major refactorings (that, while ideally transparent to the user,
      could introduce new bugs).  Incompatibilities should however not
      be introduced gratuitously and abruptly; a proper deprecation path
      should be duly implemented in the preceding minor releases.

  - According to this new scheme, the next major version of Automake
    (the one that had previously been labelled as "1.14") will actually
    become "Automake 2.0".  Automake 1.14 is *this* release (which is
    a minor one).  It introduces new features, deprecations and bug
    fixes, but no serious backward incompatibility.  A partial exception
    is given by the behavioural changes in the AM_PROG_CC_C_O macro
    (described in details below) but such changes can also be seen as a
    fix for the old suboptimal and somewhat confusing behaviour.

  - See discussion about automake bug#13578 for more details and
    background: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13578>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* WARNING: Future backward-incompatibilities!

  - Makefile recipes generated by Automake 2.0 will expect to use an
    'rm' program that doesn't complain when called without any non-option
    argument if the '-f' option is given (so that commands like "rm -f"
    and "rm -rf" will act as a no-op, instead of raising usage errors).
    This behavior of 'rm' is very widespread in the wild, and it will be
    required in the next POSIX version:

      <http://austingroupbugs.net/view.php?id=542>

    Accordingly, AM_INIT_AUTOMAKE now expands some shell code that checks
    that the default 'rm' program in PATH satisfies this requirement,
    aborting the configure process if this is not the case.  For the
    moment, it's still possible to force the configuration process to
    succeed even with a broken 'rm', that that will no longer be the case
    for Automake 2.0.

  - Automake 2.0 will require Autoconf 2.70 or later (which is still
    unreleased at the moment of writing, but is planned to be released
    before Automake 2.0 is).

  - Automake 2.0 will drop support for the long-deprecated 'configure.in'
    name for the Autoconf input file.  You are advised to start using the
    recommended name 'configure.ac' instead, ASAP.

  - The ACLOCAL_AMFLAGS special make variable will be fully deprecated in
    Automake 2.0: it will raise warnings in the "obsolete" category (but
    still no hard error of course, for compatibilities with the many, many
    packages that still relies on that variable).  You are advised to
    start relying on the new Automake support for AC_CONFIG_MACRO_DIRS
    instead (which was introduced in Automake 1.13).

  - Automake 2.0 will remove support for automatic dependency tracking
    with the SGI C/C++ compilers on IRIX.  The SGI depmode has been
    reported broken "in the wild" already, and we don't think investing
    time in debugging and fixing is worthwhile, especially considering
    that SGI has last updated those compilers in 2006, and is expected
    to retire support for them in December 2013:
    <http://www.sgi.com/services/support/irix_mips_support.html>

  - Automake 2.0 will remove support for MS-DOS and Windows 95/98/ME
    (support for them was offered by relying on the DJGPP project).
    Note however that both Cygwin and MSYS/MinGW on modern Windows
    versions will continue to be fully supported.

  - Automake-provided scripts and makefile recipes might (finally!)
    start assuming a POSIX shell in Automake 2.0.  There still is no
    certainty about this though: we'd first like to wait and see
    whether future Autoconf versions will be enhanced to guarantee
    that such a shell is always found and provided by the checks in
    ./configure.

  - Starting from Automake 2.0, third-party m4 files located in the
    system-wide aclocal directory, as well as in any directory listed
    in the ACLOCAL_PATH environment variable, will take precedence
    over "built-in" Automake macros.  For example (assuming Automake
    is installed in the /usr/local hierarchy), a definition of the
    AM_PROG_VALAC macro found in '/usr/local/share/aclocal/my-vala.m4'
    should take precedence over the same-named automake-provided macro
    (defined in '/usr/local/share/aclocal-2.0/vala.m4').

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

New in 1.14:

* C compilation, and the AC_PROG_CC and AM_PROG_CC_C_O macros:

  - The 'compile' script is now unconditionally required for all packages
    that perform C compilation (if you are using the '--add-missing'
    option, automake will fetch that script for you, so you shouldn't
    need any explicit adjustment).  This new behaviour is needed to avoid
    obscure errors when the 'subdir-objects' option is used, and the
    compiler is an inferior one that doesn't grasp the combined use of
    both the "-c -o" options; see discussion about automake bug#13378 for
    more details:
    <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#35>
    <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#44>

  - The next major Automake version (2.0) will unconditionally activate
    the 'subdir-objects' option.  In order to smooth out the transition,
    we now give a warning (in the category 'unsupported') whenever a
    source file is present in a subdirectory but the 'subdir-object' is
    not enabled.  For example, the following usage will trigger such a
    warning:

        bin_PROGRAMS = sub/foo
        sub_foo_SOURCES = sub/main.c sub/bar.c

  - Automake will automatically enhance the autoconf-provided macro
    AC_PROG_CC to force it to check, at configure time, that the
    C compiler supports the combined use of both the '-c' and '-o'
    options.  The result of this check is saved in the cache variable
    'am_cv_prog_cc_c_o', and said result can be overridden by
    pre-defining that variable.

  - The AM_PROG_CC_C_O macro can still be called, albeit that should no
    longer be necessary. This macro is now just a thin wrapper around the
    Automake-enhanced AC_PROG_CC.  This means, among the other things,
    that its behaviour is changed in three ways:

      1. It no longer invokes the Autoconf-provided AC_PROG_CC_C_O
         macro behind the scenes.

      2. It caches the check result in the 'am_cv_prog_cc_c_o' variable,
         and not in a 'ac_cv_prog_cc_*_c_o' variable whose exact name is
         dynamically computed only at configure runtime (really!) from
         the content of the '$CC' variable.

      3. It no longer automatically AC_DEFINE the C preprocessor
         symbol 'NO_MINUS_C_MINUS_O'.

* Texinfo support:

  - Automake can now be instructed to place '.info' files generated from
    Texinfo input in the builddir rather than in the srcdir; this is done
    specifying the new automake option 'info-in-builddir'.  This feature
    was requested by the developers of GCC, GDB, GNU binutils and the GNU
    bfd library.  See the extensive discussion about automake bug#11034
    for more details.

  - For quite a long time, Automake has been implementing an undocumented
    hack which ensured that '.info' files which appeared to be cleaned
    (by being listed in the CLEANFILES or DISTCLEANFILES variables) were
    built in the builddir rather than in the srcdir; this hack was
    introduced to ensure better backward-compatibility with package
    such as Texinfo, which do things like:

        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
        DISTCLEANFILES = texinfo texinfo-* info*.info*
        # Do not create info files for distribution.
        dist-info:
            @:

    in order not to distribute generated '.info' files.

    Now that we have the 'info-in-builddir' option that explicitly causes
    generated '.info' files to be placed in the builddir, this hack should
    be longer necessary, so we deprecate it with runtime warnings.  It will
    likely be removed altogether in Automake 2.0.

* Relative directory in Makefile fragments:

  - The special Automake-time substitutions '%reldir%' and '%canon_reldir%'
    (and their short versions, '%D%' and '%C%' respectively) can now be used
    in an included Makefile fragment.  The former is substituted with the
    relative directory of the included fragment (compared to the top-level
    including Makefile), and the latter with the canonicalized version of
    the same relative directory.

        # in 'Makefile.am':
        bin_PROGRAMS = # will be updated by included Makefile fragments
        include src/Makefile.inc

        # in 'src/Makefile.inc':
        bin_PROGRAMS += %reldir%/foo
        %canon_reldir%_foo_SOURCES = %reldir%/bar.c

    This should be especially useful for packages using a non-recursive
    build system.

* Deprecated distribution formats:

  - The 'shar' and 'compress' distribution formats are deprecated, and
    scheduled for removal in Automake 2.0.  Accordingly, the use of the
    'dist-shar' and 'dist-tarZ' will cause warnings at automake runtime
    (in the 'obsolete' category), and the recipes of the Automake-generated
    targets 'dist-shar' and 'dist-tarZ' will unconditionally display
    (non-fatal) warnings at make runtime.

* New configure runtime warnings about "rm -f" support:

  - To simplify transition to Automake 2.0, the shell code expanded by
    AM_INIT_AUTOMAKE now checks (at configure runtime) that the default
    'rm' program in PATH doesn't complain when called without any
    non-option argument if the '-f' option is given (so that commands like
    "rm -f" and "rm -rf" act as a no-op, instead of raising usage errors).
    If this is not the case, the configure script is aborted, to call the
    attention of the user on the issue, and invite him to fix his PATH.
    The checked 'rm' behavior is very widespread in the wild, and will be
    required by future POSIX versions:

        <http://austingroupbugs.net/view.php?id=542>

    The user can still force the configure process to complete even in the
    presence of a broken 'rm' by defining the ACCEPT_INFERIOR_RM_PROGRAM
    environment variable to "yes".  And the generated Makefiles should
    still work correctly even when such broken 'rm' is used.  But note
    that this will no longer be the case with Automake 2.0 though, so, if
    you encounter the warning, please report it to us ASAP (and try to fix
    your environment as well).
