	symlink sequences.
	(__realpath): Make real function which checks RESOLVED parameter for
	not being NULL.

1998-04-14  Ulrich Drepper  <drepper@cygnus.com>

	* catgets/open_catalog.c (__open_catalog): Fix problems with
	reading non-files.  Always close file.
	Reported by Cristian Gafton <gafton@redhat.com>.
