Subject: [PATCH] 1998-12-20  Roland McGrath  <roland@baalperazim.frob.com>

	* sunrpc/svc_unix.c, sunrpc/clnt_unix.c: Avoid using `struct cmsghdr'
	and `struct ucred' #ifndef SCM_CREDENTIALS.

	* sunrpc/publickey.c (getsecretkey): Use `&errno' instead of
	`__errno_location ()'; means the same, works for Hurd.

	* sysdeps/mach/hurd/Makefile (subdirs): Don't elide sunrpc.
