Supplemental:
 * Test TCP connection.  Makes a connection on port 5001
 * and transfers fabricated buffers or data copied from stdin.
 *
 * Usable on 4.2, 4.3, and 4.1a systems by defining one of
 * BSD42 BSD43 (BSD41a)
 * Machines using System V with BSD sockets should define SYSV.
 *
 * Modified for operation under 4.2BSD, 18 Dec 84
 *      T.C. Slattery, USNA
 * Minor improvements, Mike Muuss and Terry Slattery, 16-Oct-85.
 * Modified in 1989 at Silicon Graphics, Inc.
 *	catch SIGPIPE to be able to print stats when receiver has died 
 *	for tcp, don't look for sentinel during reads to allow small transfers
 *	increased default buffer size to 8K, nbuf to 2K to transfer 16MB
 *	moved default port to 5001, beyond IPPORT_USERRESERVED
 *	make sinkmode default because it is more popular, 
 *		-s now means don't sink/source 
 *	count number of read/write system calls to see effects of 
 *		blocking from full socket buffers
 *	for tcp, -D option turns off buffered writes (sets TCP_NODELAY sockopt)
 *	buffer alignment options, -A and -O
 *	print stats in a format that's a bit easier to use with grep & awk
 *	for SYSV, mimic BSD routines to use most of the existing timing code
 * Modified by Steve Miller of the University of Maryland, College Park
 *	-b sets the socket buffer size (SO_SNDBUF/SO_RCVBUF)
 * Modified Sept. 1989 at Silicon Graphics, Inc.
 *	restored -s sense at request of tcs@brl
