which uses $ac_objext hence depends upon _AC_OBJEXT.
* aclang.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Call
_AC_EXEEXT before _AC_OBJEXT since the former needs $ac_objext.
AM_FUNC_MKTIME, AM_FUNC_OBSTACK, AM_FUNC_STRTOD): Deactivate
their AU_ALIAS definition: Automake 1.4 does not quote the name of
these macros, hence when Autoconf reads Automake's definition the
name is expanded with unpredictable results.

* doc/autoconf.texi (Limitations of Usual Tools): Start the AWK
section.
* tests/tools.m4 (AWK portability): New test.

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

* doc/autoconf.texi (Limitations of Usual Tools): Some words about
this.

`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
: ${foo=...} trick).
(_AC_ARG_VAR_VALIDATE): Compare the two snapshots of the precious
variables.
(_AC_INIT_PREPARE): Call it after having loaded the cache file.
section, Eved off from `Preset Output Variables', i.e., was a
small part of it, grew independent, and is its equal (at least).
(Coding Style): `$#' 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.
(_AC_PROG_CC_G, AC_PROG_CC_C_O, _AC_PROG_CXX_G, AC_PROG_F77_C_O,
_AC_PROG_F77_V_OUTPUT): Use it.
* acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP, AC_COMPILE_IFELSE,
AC_LINK_IFELSE, AC_RUN_IFELSE): Likewise.
way of accessing Fortran name-mangling information other than
through CPP, and without having to know the different possible
name-mangling schemes.
* autoconf.texi: Documented AC_F77_FUNC
`size_t' which are often used too.
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.
Remove documentation of f77_case and f77_underscore.
Replace AC_F77_FUNC_WRAPPER with AC_F77_WRAPPERS.
Macros): Don't give boring internal details.
(Language Choice): Typo.
(Limitations of Builtins): Some about `!', `set', `$@'.
(Coding Style): Some about $[@] quotation.
Some about cross-compilation.
the options, and then optionally a small paragraph.
* acgeneral.m4 (AC_DIVERT_ONCE): New macro.
(HELP_VAR_END): New diversion.
(AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): Use AC_DIVERT_ONCE.
(AC_ARG_VAR): Follow the --help style.
* acspecific.m4 (AC_PATH_X): Use AC_DIVERT_ONCE.
In fact, rename this option as -A, --autoconf-dir.
* autoconf.sh: Complain when -m, --macrodir is used.
Accept -A, --autoconf-dir.
Use $autoconf_dir instead of $AC_MACRODIR.
Adjust --help.
* autoheader.sh: Likewise.
* autoscan.sh: Likewise.
* autoupdate.sh: Likewise.
Use $optarg.
* autoreconf.sh: Likewise.
* doc/autoconf.texi: Adjust.
* tests: Adjust the test suite.
when detecting the verbose flag than when scanning for linker
options, and as a result the former test failed (under AIX/xlf).
* aclang.m4 (_AC_PROG_F77_V_OUTPUT): New macro to get the
output of linking an F77 program with a given verbose flag,
and preprocess it as required to scan for linker flags.
(_AC_PROG_F77_V): Use the above macro here...
(AC_F77_LIBRARY_LDFLAGS): ...and here, enforcing consistency.
behavior of AC_CONFIG_HEADERS and AC_CONFIG_FILES with respect to
absolute and relative filenames, and stdin/stdout.

verbose messages.

(update.sh): Redirect ls's stderr to /dev/null.
leads to unnecessary warnings if both C and Fortran are checked.
(AC_PROG_F77_C_O): AC_REQUIRE AC_PROG_F77 instead of pretend you
need to be AC_BEFORE it.
causes the compiler to output verbose linking information.

simply "-v"
(AC_F77_LIBRARY_LDFLAGS): New algorithm to parse flags, uses
set/shift shell commands.

ac_cv_flibs.
* autoreconf.sh (update.sh): Use `ls -1dt' instead of `-lt'.
Use test instead of sed.
<automake>: If automake is used, always run it: it has its own
mechanism not to update if unneeded.
* acgeneral.m4 (AC_SHELL_DIRNAME): When using m4 the argument
is named `$1' not `$dir'.
When using m4 you ought to quote properly.
When using m4, you should check that there are not too many shell
quotes (inside the macro itself, and where it is called).
When you do this, Autoconf, hm, works better.
* acgeneral.m4 (_AC_INIT_HELP): Direct reader to descriptions
of useful variables at the end of the --help.
(AC_ARG_VAR): Emphasize use of environment variables to override
and/or help the configure script. Ensure that a given variable
is only documented once in the --help.

LDFLAGS variable, and...

the CC and CFLAGS variables, and do the same for...

(AC_PROG_F77): F77 and FFLAGS.

* acgeneral.m4 (_AC_LIBOBJ): Same as the former AC_LIBOBJ, but
takes an additional argument: action to perform when non-literal
argument.
(AC_LIBOBJ): Use it.
(AC_REPLACE_FUNCS): Use _AC_LIBOBJ, not AC_LIBOBJ.
In fact, honor the most recent specification in the concatenation
of `syntax',$WARNINGS,<options> in that order.
Implement support for `none' and `noCATEGORY' so that the options
may override the previous choices.
Suggested by Didier Verna.
* acgeneral.m4 (_AC_WARNING_IFELSE): New macro.
(AC_WARNING_IFELSE): Use this macro to implement the new specs.
(AC_WARNING): The empty category must not be used, default to

Use `optarg' to fetch the arguments of options.
Fix a bug in the handling of `--trace='.
* acgeneral.m4 (AC_CACHE_VAL): Typo: the macro was complaining iff
it shouldn't have.
`aclocal.m4' and that of the location Autoconf extensions.
(-M, --m4dir): New option.
(aclocal_flags): Do not use $localdir, but $m4dir.
