(top level)

2004-03-11  Nathanael Nerode  <neroden@gcc.gnu.org>

	* configure: Regenerate.

2004-03-08  Paolo Bonzini  <bonzini@gnu.org>

	PR ada/14131
	Move language detection to the top level.
	* configure.in: Find default values for the tools as
	soon as possible.  Disable ada if GNAT is not found.
	Emit error message about missing languages.  Expand
	--enable-languages=all for the gcc subdirectory.

(config)
2004-03-08  Paolo Bonzini  <bonzini@gnu.org>

	PR ada/14131
	Move language detection to the top level.
	* acx.m4 (ACX_PROG_GNAT): New macro, moved here
	from the gcc subdirectory.

2004-03-09  Hans-Peter Nilsson  <hp@axis.com>

	* accross.m4 (AC_C_BIGENDIAN_CROSS): Compile endian probe with
	"-c".  Properly quote parameter for AC_MSG_ERROR.
