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