	* configure.in: Add AC_TYPE_GETGROUPS to determine argument to
	getgroups.

	* auth_unix.c (authunix_create_default): Use GETGROUPS_T array in
	call to getgroups. Copy into array of int for call to
	authunix_create. Note: If auth_unix protection ever used with this
	code, we will need to cleanup assumptions in int being 32 bits in
	OTW transfer of gids.

	* clnt_tcp.c, svc_tcp.c: Change writetcp and readtcp to take char
	* as first argument to be compatible with xdrrec_create.

	* xdr.c (xdr_opaque): Cast argument in call to XDR_GETBYTES.

	* svc.h: Add prototype for gssrpc_svcudp_enablecache.

	* svc_auth_gssapi.c (_gssrpc_svcauth_gssapi): Change
	_svcauth_gssapi to _gssrpc_svcauth_gssapi for consistancy.

	* svc_auth.c: Move prototypes for _gssrpc_svcauth_{unix, null,
	short, gssapi} to:
	* svc_auth.h: here.

	* svc_auth_unix.c: Update _gssrpc_svcauth_short and
	_gssrpc_svcauth_unix to match prototype.
