                      9: # DESCRIPTION
                     10: #
                     11: #   This macro figures out what libraries are required on this platform to
                     12: #   link sockets programs.
                     13: #
                     14: #   The common cases are not to need any extra libraries, or to need
                     15: #   -lsocket and -lnsl. We need to avoid linking with libnsl unless we need
                     16: #   it, though, since on some OSes where it isn't necessary it will totally
                     17: #   break networking. Unisys also includes gethostbyname() in libsocket but
                     18: #   needs libnsl for socket().
