literal AWK program that performed the `oline' and quadrigraphs
substitution.
Fix its `oline' computation which was dead wrong when there are
empty lines (i.e., always).
Enhance it in order to look for and report unexpanded macro.
Don't let it pretend there are bugs in Autoconf (c:, the test
suite makes this scenario pretty unlikely as opposed to an actual
user bug.
Catch `m4_' too.
Remove the shell snippet which used to do this.

In fact, let's just use the precious variables handling.
* acgeneral.m4 (AC_VALIDATE_CACHED_SYSTEM_TUPLE): Obsoleted.
(_AC_ARG_VAR_PRECIOUS): New macro, eved from...
(AC_ARG_VAR): this macro. Adjust.
(_AC_INIT_PREPARE): `build_alias', `host_alias', and
`target_alias' are precious.
* doc/autoconf.texi: Adjust.
(_AC_DIVERT(PARSE_ARGS)): this. Adjust dependencies.
(AC_ARG_WITH): Remove spurious newline.
(AC_ARG_VAR): No longer save precious variables in
ac_configure_args, rather snapshot them twice (one kept
unmodified, another one to be written to/overwritten by the cache
file).
(AC_CACHE_SAVE): Let the cache variables named `ac_cv_env_*'
be overwritten when loading the cache (i.e., don't use the
: ${foo=...} trick).
(_AC_ARG_VAR_VALIDATE): Compare the two snapshots of the precious
variables.
(_AC_INIT_PREPARE): Call it after having loaded the cache file.

small part of it, grew independent, and is its equal (at least).
(Coding Style): `$#' padding.
* Makefile.am (editsh, editpl): Do what the doc says you do: use
@datadir\@ instead of @''datadir''@.
_AC_PROG_F77_GNU): Use ac_ext. Use ACEOF instead of EOF.
(AC_LANG_CONFTEST): New macro.

Fix a bug which prevents recognition of `bool' and `char'.
(_AC_CHECK_TYPE_MAYBE_TYPE_P): New macro.
(AC_CHECK_TYPE): Use it.
_AC_F77_NAME_MANGLING.
(_AC_F77_NAME_MANGLING): Use independent checks for the
name mangling of symbols with and without underscores.
Use algorithm with for loops instead of recursive macro calls.
(AC_F77_WRAPPERS): Adapt to changes in _AC_F77_NAME_MANGLING.
* doc/autoconf.texi (Fortran 77 Compiler Characteristics):
Remove documentation of AC_F77_NAME_MANGLING.

Replace AC_F77_FUNC_WRAPPER with AC_F77_WRAPPERS.
