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.
