Umm, I'm not sure what issues you're having.  I've compiled that code
segment under solaris.  ip_mreq is defined in /usr/include/netinet/in.h.
there were issues with using ip_mreqn and using SOL_IP instead of
IPPROTO_IP, but both of those have been fixed.

yes, these are the multicast socket options and use the ip_mreq struct.
