and YP_SECURE flags so that it can properly add them to newly created maps when needed. This applies only when using the 'standard' method for map transfers. When using rpc.ypxfrd, the whole map is copied verbatim, along with any special entries that may be encoded in it. Also made -Wall a little quieter for ypxfrd_getmap.c.
