Author: Paolo Bonzini <address@hidden>
Date: Mon Nov 3 10:25:23 2008 +0100
Dispatch on AC_LANG_CONFTEST
* lib/autoconf/c.m4 (AC_LANG_CONFTEST(C)): Define instead of
AC_LANG_SOURCE(C).
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Add a comment at the
top of confdefs.h, which also works around cpp deficiencies.
* lib/autoconf/lang.m4 (AC_LANG_DEFINE): Define AC_LANG_CONFTEST(xyz)
(AC_LANG_CONFTEST): Dispatch based on _AC_LANG.
(AC_LANG_CONFTEST()): New.

_AC_LANG_ABBREV(Fortran), _AC_LANG_ABBREV(Fortran 77),
_AC_LANG_PREFIX(Fortran), _AC_LANG_PREFIX(Fortran 77),
_AC_LANG_SOURCE(Fortran), AC_LANG_SOURCE(Fortran 77)): Replace
