	[BZ #1111]
	* nis/nss_compat/compat-grp.c (internal_getgrgid_r): Check if NSS
	module provides getgrgid_r.
	(getgrnam_plusgroup): Preserve original return value.
	* nis/nss_compat/compat-pwd.c (getpwnam_plususer): Preserve
	original return value.
	* nis/nss_compat/compat-spwd.c (getspnam_plususer): Likewise.
