Mon Dec 17 17:02:12 2001 Nicola Pero <nicola@brainstorm.co.uk>
* init.c (__objc_exec_class): Fixed bug in the loop on unclaimed
categories - when an unclaimed category was found, the loop was

Ditto.
Mon Jul 16 12:15:00 2001 Nicola Pero <n.pero@mi.flashnet.it>
* objc/objc-api.h (object_is_class): Fixed - buggy code was trying
to cast an id to a Class, which can not be done. Make the check
by using CLS_ISMETA on the class pointer instead.

always use thr-objc.c as a backend, which uses GCC's thread code.
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.
2001-05-25 Ovidiu Predescu <ovidiu@cup.hp.com>
* init.c (__objc_send_message_in_list): When setting a new entry
in __objc_load_methods use the method name as key, not the method
IMP (reported by Richard Frith-Macdonald <richard@brainstorm.co.uk>).

friends have on various platforms. (Solution suggested by Helge
Hess.)
