I've updated the patch to set the multicast group from
$FREECIV_MULTICAST_GROUP.   The default value is 224.0.0.1.

There's nothing in http://www.faqs.org/rfcs/rfc1112.html
which states that a multicast group address set to
224.0.0.1 should be problematic for the applications used here.

Anyone able to produce problems with this patch now?
