1295    #    order in the command line generated by make.  Here are some
1296    #    special considerations:
1297    #    1. Use "connect" and "accept" to check for -lsocket, and
1298    #       "gethostbyname" to check for -lnsl.
1299    #    2. Use each function name only once:  can't redo a check because
1300    #       autoconf caches the results of the last check and won't redo it.
1301    #    3. Use -lnsl and -lsocket only if they supply procedures that
1302    #       aren't already present in the normal libraries.  This is because
1303    #       IRIX 5.2 has libraries, but they aren't needed and they're
1304    #       bogus:  they goof up name resolution if used.
