7# AX_LIB_SOCKET_NSL
8#
9# DESCRIPTION
10#
11# This macro figures out what libraries are required on this platform to
12# link sockets programs.
13#
14# The common cases are not to need any extra libraries, or to need
15# -lsocket and -lnsl. We need to avoid linking with libnsl unless we need
16# it, though, since on some OSes where it isn't necessary it will totally
17# break networking. Unisys also includes gethostbyname() in libsocket but
18# needs libnsl for socket().
