Update.

1999-05-16  Thorsten Kukuk  <kukuk@suse.de>

	* sunrpc/etc.rpc: Add portmapper, rstat_svc and pcnfs.
	* sunrpc/key_call.c: Fix memory leak, close file handle.
	* nis/nis_creategroup.c: Use malloc instead of calloc,
	set ctime and mtime.
	* nis/nis_subr.c: Check for realloc result.
	* nis/nis_file.c: Fix memory leak.
	* nis/nis_table.c: Pretty print.
	* nis/nis_getservlist.c: Likewise.
	* nis/nis_ismember.c: Likewise.
	* nis/nis_lookup.c: Likewise.
	* nis/nis_ping.c: Likewise.
	* nis/nis_removemember.c: Likewise.
	* nis/nis_util.c: Likewise, check calloc result.
