Ulrich Drepper b677d67428 Update.
2003-01-19  Ulrich Drepper  <drepper@redhat.com>

	* nis/nss_nis/nis-spwd.c: Make _nss_nis_endspent an alias of
	_nss_nis_setspent.  Work around the different prototypes.
	* nis/nss_nis/nis-rpc.c (internal_nis_setrpcent): Use
	internal_nis_endrpcent.
	(internal_nis_endrpcent): Change return type to void.  Change callers.
	* nis/nss_nis/nis-pwd.c: Make _nss_nis_endpwent an alias of
	_nss_nis_setpwent.  Work around the different prototypes.
	* nis/nss_nis/nis-proto.c (_nss_nis_endprotoent): Split out body
	of the function to...
	(internal_nis_endprotoent): ... here.  New function.
	(internal_nis_setprotoent): Use internal_nis_endprotoent.
	* nis/nss_nis/nis-network.c: Make _nss_nis_endnetent an alias of
	_nss_nis_setnetent.  Work around the different prototypes.
	* nis/nss_nis/nis-netgrp.c (_nss_nis_endnetgrent): Split out body
	of the function to...
	(internal_nis_endnetgrent): ... here.  New function.
	(_nss_nis_setnetgrent): Use internal_nis_endnetgrent.
