Mon Jan 11 13:31:49 1999  Tim Janik  <timj@gtk.org>

        * gtk/gtktypeutils.[hc]: removed Paolo Molaro's type creation hooks
        again, since they 1) don't care about infinite recursion (likely
        to achive), 2) we are in feature freeze for 1.2. this definitely
        deserves a sane implementation in 1.3 though (but without a hook
        return value, without seq_id hackery and with recursion checks).
