+Subject: [PATCH 2/2] [mmulti.c] #ifdef out network-related stuff we currently
+ do not support
+
+This patches out network-relatd stuff like IP_PKTINFO, IPV6_PKTINFO, and
+IP_RECVDSTADDR which we currently do not support.
+
+This is merely done to make the code compile, and since we do not try to
+support any multiplayer option or other network-related stuff it should
+not matter for the time being.
