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