2001-06-06  Richard Frith-Macdonald  <rrfm@gnu.org>

        * init.c (__objc_send_message_in_list): When setting a new entry
        in __objc_load_methods use the method IMP as key, but check to see
        if the method is in the hashtable by looking at the IMP also.
        Also ... call the method after adding it to the hashtable rather
        than before ... thus preventing an obscure possibility of infinite
        recursion if a +load method itself loads a subclass.
