Autoconf 2.54c is relased

User-agent: Gnus/5.0808 (Gnus v5.8.8) XEmacs/21.4 (Honest Recruiter)

The Autoconf team -- Akim, Alexandre, Jim, Paul, and Tom -- is happy
to annonce the second beta of forthcoming Autoconf 2.55.  Download,
compile, install, torture, and enjoy!

  - Why should I upgrade from 2.54?

A few bug fixes, improved portability, no known incompatibility with
2.54 and 2.55, forthcoming Gettext release might require 2.55.

Running `autoreconf -fv' should be enough.

   - Why should I upgrade from 2.13?

This version is no longer maintained.  It does not address recent
architectures, recent compilers etc.  We know that upgrading from 2.13
to 2.5x is not an easy task, especially because the Autoconf 2.13 was
extremely tolerant to incorrect macro invocations, but waiting longer
endangers the portability of your package and only delays the
conversation to newer Autoconf versions.  Worse: some maintainers now
spend a significant amount of time fixing bugs in 2.13 or backporting
macros from 2.55.

   - Where can I find it?   (1.1 MB)  (792 KB)

And here are xdelta-style diffs   (17 KB)

Here are the MD5 and SHA1 signatures:

Release tips:

           Have your checked by autoscan ("autoscan").
           Try the warning options ("autoreconf -fv -Wall").

** Documentation

  More information on proper use.

- Writing Test Programs

  This sections explains how to write good test sources to use with
  AC_COMPILE_IFELSE etc.  It documents AC_LANG_PROGRAMS and so forth.


  Explains why Autoconf moves from AC_TRY_COMPILE etc. to

** autoreconf

- Is more robust to different Gettext installations.

- Produces messages (when --verbose) to be understood by Emacs'
  compile mode.

- Supports -W/--warnings.

- -m/--make
  Once the GNU Build System reinstalled, run `./config.status
  --recheck && ./config.status && make' if possible.

** autom4te

- Supports --cache, and --no-cache.

- ~/.autom4te.cfg makes it possible to disable the caching mechanism
  (autom4te.cache).  See `Customizing autom4te' in the documentation.

** Obsolete options

  Support for the obsoleted options -m, --macrodir, -l, --localdir is
  dropped in favor of the safer --include/--prepend-include scheme.

** Macros

- New macros

- Obsoleted
  Obsoleted macros are kept for Autoconf backward compatibility, but
  should be avoided in  Running autoupdate is advised.

** Bug Fixes

- Portability of the Autoconf package to Solaris.

- Spurious warnings caused by config.status.
  This bug is benign, but painful: on some systems (typically
  FreeBSD), warnings such as:

     config.status: creating Makefile
     mv: Makefile: set owner/group (was: 1357/0): Operation not permitted

  could be issued.  This is fixed.

- Parallel Builds
  Simultaneous executions of config.status are possible again.

- Precious variables accumulation

  config.status could stack several copies of the precious variables

** Plans for 2.56

- ./configure <host>

  The compatibility hooks with the old scheme will be completely
  removed.  Please, advice/use `--build', `--host', and `--target'


  The tests will be stricter, please make sure your invocations are

- shell functions

  Shell functions will gradually be introduced, probably starting with
  Autotest.  If you know machines which are in use that you suspect
  *not* to support shell functions, please run the test suite of
  Autoconf 2.55 on it, and report the results to
