#       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.
