|
# 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.
