So this means that the lan-patch for Freeciv would also work on Solaris
2.8? I would think so.

I just tested the lan-patch on a SunOS 5.9 (Solaris 7 x86), and
it works (just like Linux) for any multicast group I choose.

So far, only Netbsd has insisted on using only the all-hosts group.
Could it be a bug in NetBsd? Can it be solved by using autoconf?
