./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 $(CONFIG_LANGUAGES) instead of @all_languages@
(Makefile): Pass actual LANGUAGES through the environment when
re-configuring.
(cstamp-h): Likewise.
(config.status): Likewise.
* configure.in (enable_languages): Add new configuration parameter
"--enable-languages=lang1,lang2,...".
(${srcdir}/*/config-lang.in): Change handling to configure only
those directories, that the user might have enabled; default to
"all" existing languages.
* configure: Regenerate.
./libchill/ChangeLog:1998-11-26 Manfred Hollstein <manfred@s-direktnet.de>
* configure.in (compiler_name): Add check to detect if this
language's compiler has been built.
* configure: Regenerate.
./libf2c/ChangeLog:1998-11-26 Manfred Hollstein <manfred@s-direktnet.de>
* configure.in (compiler_name): Add check to detect if this
language's compiler has been built.
* configure: Regenerate.
./libio/ChangeLog:1998-11-26 Manfred Hollstein <manfred@s-direktnet.de>
* configure.in (compiler_name): Add check to detect if this
language's compiler has been built.
./libobjc/ChangeLog:1998-11-26 Manfred Hollstein <manfred@s-direktnet.de>
* configure.in (compiler_name): Add check to detect if this
language's compiler has been built.
* configure: Regenerate.
./libstdc++/ChangeLog:1998-11-26 Manfred Hollstein <manfred@s-direktnet.de>
* configure.in (compiler_name): Add check to detect if this
language's compiler has been built.
