* clnt_raw, clnt_tcp.c, clnt_udp.c: Use a union structure to

	ensure argument alignment.

	* pmap_clnt.c, pmap_clnt.h (pmap_set): Change port argument to int
	to avoid width warnings.

	* rpc_callmsg.c (xdr_callmsg): Cast argument to XDR_INLINE to
	avoid signed vs. unsigned warning.

	* svc.c: Cast assignment to avoid signed warning.

	* xdr.c (xdr_u_short, xdr_u_long): cast pointers to long * in
	invocation of XDR_PUTLONG.

	* xdr_alloc.c (xdralloc_putbytes): Cast argument to DynInsert to
	avoid signed/unsigned warning.

	* auth_gssapi.c, svc_auth_gssapi, xdr_rec.c: Cast arguments to
	avoid alignment warnings.

	* svc_tcp.c, xdr_stdio.c: Cast argument to fread/fwrite/read/write.
