There was a better patch that made it an option in resolv.conf,
rather than turning it on all the time.

FreeBSD should be standards compliant, by default, and take work
to make it possible to give bogus data to other hosts on the
Internet who can not handle "_" or other characters because they
*are* standars compliant.
