   I don't know what ifconfig does use as a default, but if you use the `ip'
   command to set up the interfaces, default broadcast address is `none' and
   BIRD correctly defaults that to the last address in the net.

ifconfig sets the last address in the Class C, not the net.

   I've added
   a check for broadcast address sanity to BIRD (see the patch below), so that
   it now complains loudly if it gets an invalid one.

Added, and that may stop some problems.
