And it's _still_ a red herring.

I just booted a !CONFIG_IGMP kernel on my workstation and NTP is running
just fine (as is IPv6).

Even though ntpd has a configure test for multicast and can be built
without multicast support at all, it isn't even necessary to build it
that way -- the stock Fedora build of it works just fine.

(Actually, I never managed to get ntpd to work _with_ multicast, but
that's a different issue... :)
