./ChangeLog:

1998-11-26  Manfred Hollstein  <manfred@s-direktnet.de>
	* configure (skip-this-dir): Add handling for new shell script, which
	might be created by a sub-directory's configure to indicate, this particular
	directory is "unwanted".
	* Makefile.in ($(CONFIGURE_TARGET_MODULES)): Likewise.
./gcc/ChangeLog:
1998-11-26  Manfred Hollstein  <manfred@s-direktnet.de>
	* Makefile.in (CONFIG_LANGUAGES): New macro taking all languages
	which can be configured.
	(LANGUAGES): Use $(CONFIG_LANGUAGES) instead of @all_languages@
	(Makefile): Pass actual LANGUAGES through the environment when
	re-configuring.
	(cstamp-h): Likewise.
