Update.

2002-04-11  Zack Weinberg  <zack@codesourcery.com>

	* include/rpc/rpc.h (struct rpc_thread_variables): Remove
	authnone_private_s.
	* sunrpc/auth_none.c: Include bits/libc-lock.h.
	Delete #ifdef _RPC_THREAD_SAFE_ block.
	(authnone_private): Make a struct, not a pointer to struct.
	(authnone_private_guard): New once-control variable.
	(authnone_create_once): New function, split out of
	authnone_create.  No need to allocate memory.
	(authnone_create): Just call authnone_create_once via
	__libc_once, then return &authnone_private->no_client.
	(authnone_marshal): Access private data via CLIENT argument,
	not authnone_private pointer.
	Fix typo (MAX_MARSHEL_SIZE -> MAX_MARSHAL_SIZE).
	* sunrpc/rpc_thread.c (__rpc_thread_destroy): No need to free
	authnone_private_s.
