 *  Last Modified:		29 Jun 90
 *  Comments:
 *  History:
 *		02 Jan 89	Added accept/broadcast functions and IPC_ADDRESS.
 *		09 Oct 89	Fake FD_SET et. al. to work like pre-SunOS 4.0 select()
 *					expects.  Some 3.4 systems have fd_set typedef'ed in
 *					<sys/types.h> but not used anywhere.  Define BOGUS_FD_SET
 *					for such rude systems.
 *		29 Jun 90	FD_SETSIZE should be size of an integer in bits,
 *					not bytes.
