# 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.

# 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
