1997-10-31 23:16  Ulrich Drepper  <drepper@cygnus.com>

	* posix/glob.c (glob): If calling glob_in_dir for a list which was
	generated by a glob call disable GLOB_ERR since there might be
	non-directories in the list (PR203).

	(__GLOB_FLAGS): Add GLOB_ONLYDIR.
	* posix/glob.c: Define HAVE_D_TYPE if _DIRENT_HAVE_D_TYPE is defined.
	(glob): Add GLOB_ONLYDIR to recursive call to match dirname.
	(glob_in_dir) [HAVE_D_TYPE]: While reading directory entries test
	whether they are directories if GLOB_ONLYDIR flag is given.
	* manual/pattern.texi: Document GLOB_ONLYDIR.
