#	Check for the existence of the -lsocket and -lnsl libraries.
#	The order here is important, so that they end up in the right
#	order in the command line generated by make.  Here are some
#	special considerations:
#	1. Use "connect" and "accept" to check for -lsocket, and
#	   "gethostbyname" to check for -lnsl.
#	2. Use each function name only once:  can't redo a check because
#	   autoconf caches the results of the last check and won't redo it.
#	3. Use -lnsl and -lsocket only if they supply procedures that
#	   aren't already present in the normal libraries.  This is because
#	   IRIX 5.2 has libraries, but they aren't needed and they're
#	   bogus:  they goof up name resolution if used.
#	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
#	   To get around this problem, check for both libraries together
#	   if -lsocket doesn't work by itself.
