* nis/nss_compat/compat-pwd.c (internal_setpwent): If nss_set*ent

	returned NSS_STATUS_UNAVAIL, still return NSS_STATUS_SUCCESS.
	* nis/nss_compat/compat-spwd.c (internal_setspent): Likewise.
	* nis/nss_compat/compat-grp.c (internal_setgrent): Likewise.

	* nis/nss_compat/compat-initgroups.c (nss_setgrent, nss_endgrent):
	Removed.
	(init_nss_interface): Remove initialization of these variables.

2006-05-18  Ulrich Drepper  <drepper@redhat.com>

	* nis/nis_call.c (rec_dirsearch): Little optimization: pull
	nis_free_directory forward to avoid duplication.
