* acgeneral.m4 (_AC_CACHE_DUMP): New macro.
(AC_CACHE_SAVE, AC_OUTPUT): Use it.
(AC_OUTPUT): Dump confdefs.h into config.log.
(_AC_INIT_PREPARE::config.log): Name the package being configured
if you can.
newbies accidentally use a stale cache file.
* acgeneral.m4 (_AC_INIT_PARSE_ARGS): Set cache_file to /dev/null
to disable caching by default.
(_AC_INIT_HELP): Adjust the --help message.
(AC_CACHE_LOAD, AC_CACHE_SAVE): Don't print "loading/updating
/dev/null" messages.
* autoconf.texi: Note that caching is disabled, how to enable it,
and that `./config.cache' is the traditional name of the cache file.
* install.texi: Likewise.

* aclang.m4 (AC_F77_NAME_MANGLING): Extract f77_case,
f77_underscore from cache variable.
(AC_F77_WRAPPERS): Get rid of ac_cv_f77_wrappers, it's useless.
Simplify the nested case-esac into a single one.
Simplify the documentation strings of CPP symbols.
* autoheader.m4: Dispatch the prototypes next to there AC_
siblings.
(AH_TEMPLATE, AH_VERBATIM): Move to...
* acgeneral.m4: here.
(AH_OUTPUT): New macro.
* autoheader.sh: Run `autoconf --trace' instead of `m4 autoheader.m4'.
* autoheader.m4: Remove.
* Makefile.am: Adjust.
* tests/tools.m4 (AH_DEFUN): Remove, no longer makes sense.
* tests/actests.m4 (autoheader::AC_TATOOINE): Remove, was used by
the test above.

argument of the explicit AC_INIT call is lost.
* acgeneral.m4 (AC_CONFIG_SRCDIR): New macro.
(_AC_INIT_SRCDIR): Adjust.
(_AC_INIT): Pass your argument to AC_CONFIG_SRCDIR.
* libm4.m4 (m4_append, m4_list_append): Use m4_define, not define.
On my machine the former implementation takes 4mn 40s to run the
test suite. Using m4_define leads to 4mn 15s.
* acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
m4_define, not define). 4mn.
(_AC_DIVERT): Don't use m4_case. Starting from those 4mn, if you
just move NORMAL* first in m4_case, the test suite is run in 3mn.
If instead of using m4, you use an `associative array' plus a
wrapper (current implementation), it falls to 2mn.
* acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Prefer
