        !            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().
