41ec08f9ed When running 
AC_INIT
AC_PROG_CC
AC_LANG_COMPILER_REQUIRE
AC_PROG_CC is expanded twice, because AC_PROG_CC provides
`AC_PROG_CC', and not `AC_LANG_COMPILER(C)' as expected by
AC_LANG_COMPILER_REQUIRE.
* aclang.m4 (AC_LANG_COMPILER(C)): Instead of calling AC_PROG_CC,
require it.
(AC_LANG_COMPILER(C++), AC_LANG_COMPILER(Fortran 77)): Likewise.

603fad0c9c * autoconf.sh: Temporarily disable recognizing of abbreviated

674d4eef25 m4_syscmd was reestablished as syscd' intead of syscmd' because 
instead of `s/^m4_//', m4_copy_unm4 was running `s/[m4_]//'.
* m4sugar.m4 (m4_copy_unm4): Fix.
 2000-11-07 11:49:35 +00:00

b4a8fae52b AC_CONFIG_AUX_DIR_DEFAULTS overrides AC_CONFIG_AUX_DIR. Ouch. 
Reported by Paul Martinolich.
* acgeneral.m4 (AC_PROVIDE): Don't forget to `m4_provide'!!!
Tss, novice...
* tests/base.at (AC_REQUIRE & AC_PROVIDE): New test.
 2000-11-03 16:02:54 +00:00
Akim Demaille
43703ea9aa * m4sugar.m4 (m4_location): When using its value, don't use 
`m4_defn', since m4_location is not a variable, it's a macro which
expands to __file__:__line__.
* tests/m4sugar.at (m4_warn): New test.
 2000-11-03 15:21:14 +00:00
Akim Demaille
f1ba26c218 * tests/tools.at (unexpanded macros): Strengthen.

ded24ff599 * autoconf.m4 (define): Reestablish only after having read the 
`ac' files.
Adjust all the Autoconf code to use `m4_define', not `define'.
 2000-11-03 13:41:40 +00:00
Akim Demaille
3c3853ced4 * acgeneral.m4 (AU_ALIAS): Don't forget to pass the arguments to 
the new macro...
Reported by Ezra Peisach.
* tests/semantics.m4 (AC_HAVE_FUNCS): New test.
* tests/tools.at (autoupdate): As a benign side effect, updating a
macro that takes no argument produces `UPDATED([])', no longer
`UPDATED()'.  Adjust the test.
 2000-11-03 11:59:39 +00:00
Akim Demaille
7e4f776a09 * autoconf.m4: Instead of reactivating the macros before reading 
Autoconf's file, do it afterwards, so that Autoconf promotes the
right use, but users still can use the old names.
Of course this revealed numerous non updated uses of old macros in
Autoconf's files.  Adjust them.
But for the time being, keep `define' alive for Autoconf.

1c614b9e79 AC_REQUIRE and AC_DEFUN_ONCE don't work properly together. This

m4_defun_once.

9fe2458f8d Set up config.log earlier so that AC_MSG_ERROR and AC_MSG_WARN can 
be used early.
* acgeneral.m4 (_AC_INIT_DEFAULTS): Call `_AC_INIT_PREPARE_FDS'.
(_AC_INIT_PREPARE): Don't.
(_AC_INIT_PREPARE_ENVIRONMENT, _AC_INIT_PREPARE_FDS): Rename as...
(_AC_INIT_DEFAULTS_ENVIRONMENT, _AC_INIT_DEFAULTS_FDS): these,
since they are called from `_AC_INIT_DEFAULTS', not
`_AC_INIT_PREPARE'.
(_AC_INIT_DEFAULTS_FDS): Dump `$@' in config.log, not
`$ac_configure_args' which is not computed yet.

Akim Demaille
3f580f38ab * m4sh.m4 (_AS_UNSET_PREPARE): New macro, eved from 
_AC_INIT_PREPARE_ENVIRONMENT, and fixed: set `FOO' before trying
to unset it: `unset' exits 1 if the variable is not defined.
(AS_UNSET): Require it.  Use `as_unset' not `ac_unset'.
* acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): Use it.

528a6b7122 The documentation is not clear about the obsoleteness of 
`acconfig.h', `config.h.top', and `config.h.bot'.
Reported by Aharon Robbins.
* doc/autoconf.texi (Making configure Scripts)

these files.

e015643d3f * tests/atgeneral.m4 (AT_CHECK): Check stderr first, since if both 
stdout and stderr fail, differences on the latter are probably
more significant than on the former.

Akim Demaille
648bf798eb * autoconf.sh (task trace) [debug]: Instead of a long pipe, extend
