I am running XORP-1.0.
OpenBSD-3.6 also has the compiler bug. I build gcc-3.3.2 from ports, and
it is much happier now. Some fo the bgp/harness tests seem to fail, but 
a lot more works than with gcc-2.95.

Can you take a look at the included config file and tell me if this
looks right? The vlan127 interface is statically configured, and
connected to a Cisco router running PIM-SM. I want multicast traffic on
em1 to get propagated back up to the multicast RP.
