Looks like I fixed it.  I made on inet_ops and the other cidr_ops. 
Those names should be unique in there anyway.  They are just used when
specifying the ops on an index create.  The zero entries I just set to
dummy values for int24 and int42 because there are no type that match
them.  I set their typedef to be the same as the ops oid.  Hope the
sanity check doesn't complain.
