HEADS-UP: autoconf 2.57 and automake 1.7.2 available

[Matthias Andree]

Hi,

I've seen on the Aachen GNU mirror that autoconf 2.57 and automake 1.7.2
are now available, excerpts from the respective NEWS files
below.

I've run autoreconf -fsvi and re-run make check, it passed, so no
show-stoppers on my machine.

* Major changes in Autoconf 2.57                       -*- outline -*-

  Released 2002-12-03.

Bug fixes for problems with AIX linker, with freestanding C compilers,
with GNU m4 limitations, and with obsolete copies of GNU documents.

The Free Documentation License has been upgraded from 1.1 to 1.2.
(automake)
Bugs fixed in 1.7.2:
* Fix installation and uninstallation of Info files built in subdirectories.
* Do not run `./configure --with-included-gettext' during `make distcheck'
  if AM_GNU_GETTEXT([external]) is used.
* Correctly uninstall renamed man pages.
* Do not strip escaped newline in variables defined in one condition
  and augmented in another condition.
* Fix ansi2knr rules for LIBOBJS sources.
* Clean all known Texinfo index files, not only those which appear to
  be used, because we cannot know wich indexes are used in included files.
  (PR/375, Debian Bug #168671)
* Honor only the first @setfilename seen in a Texinfo file.
* Treat "required file X not found" diagnostics as errors (exit status 1).
* Don't complain that a required file is not found when it is a Makefile
  target. (PR/357)
* Don't use single suffix inference rules when building `.info'-less
  Info files, for the sake of Solaris make.
* The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
* Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
* Warn about multiple inference rules when -Wportability is used. (PR/372)
* Fix building of deansified files from subdirectories. (PR/370)
* Add missing `fi' in the .c->.obj rules.
* Improve install-sh to work even when names contain spaces or certain
  (but not all) shell metachars.
* Fix the following spurious failures in the test suite:
  depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
* Noteworthy manual updates:
  - Augment the section about BUILT_SOURCES.
  - Mention that AM_PROG_CC_STDC is a relic that is beter avoided today.
