That sounds pretty serious, I'm sorry to hear that. Can you provide full 
detail(s) of the errors you are seeing? I am actively hacking on the 
code base on FreeBSD 7.2-STABLE right now, and do not see any compile 
failures with SVN trunk with a fresh compile.

We no longer have tinderbox coverage for the community branch, so we do 
depend on volunteers reporting tree breakage; however we really need 
full details of such breakage to be able to help out.

If you look at site_scons/config/allconfig.py, around line 406, you can 
see where HAVE_IPV4_MULTICAST is defined by the SCons configuration 
tests. I haven't tested with Ubuntu or Fedora in a few weeks.

The tests for HAVE_IPV4_MULTICAST all run successfully on my system. The 
tests are quite simple, they just check for the relevant headers and 
declarations (IP_MULTICAST_IF, IP_MULTICAST_TTL, IP_MULTICAST_LOOP, 
IP_ADD_MEMBERSHIP, IP_DROP_MEMBERSHIP). If all of these are present, 
then HAVE_IPV4_MULTICAST will be defined.

Can you please provide your config.log and xorp_config.h file, uname -a 
output, so we can try to help you better?

Is there anything special or different about your machine from a base 
FreeBSD install (have you modified any kernel headers, is this a fresh 
copy of FreeBSD, source installed, did you use buildworld/installworld 
etc) ?
