	* catgets/open_catalog.c (__open_catalog): Decide about use of
	path by examining path in struct, not based on extra argument.
	Acquire a the lock before trying to load the catalog and release
	it before returning.

	* csu/Makefile (abi-tag.h): Make sure target directory exists.

	* io/Makefile (headers): Add bits/poll.h.

	* malloc/obstack.c: Add casts to keep very verbose compilers on
	64bit machine quiet.

	* nss/Makefile (libnss_db.so): Find libdb.so in db2 directory.

1997-08-28 17:30  Ulrich Drepper  <drepper@cygnus.com>
