897 Mon Jul 16 12:15:00 2001 Nicola Pero <n.pero@mi.flashnet.it>
899 * objc/objc-api.h (object_is_class): Fixed - buggy code was trying

909 * configure: Rebuilt.
911 2001-06-08 Nicola Pero <n.pero@mi.flashnet.it>

916 2001-06-06 Richard Frith-Macdonald <rrfm@gnu.org>
918 * init.c (__objc_send_message_in_list): When setting a new entry
919 in __objc_load_methods use the method IMP as key, but check to see
920 if the method is in the hashtable by looking at the IMP also.
921 Also ... call the method after adding it to the hashtable rather
922 than before ... thus preventing an obscure possibility of infinite
923 recursion if a +load method itself loads a subclass.
925 2001-05-25 Ovidiu Predescu <ovidiu@cup.hp.com>
927 * init.c (__objc_send_message_in_list): When setting a new entry
928 in __objc_load_methods use the method name as key, not the method

992 Wed Jan 3 00:49:10 2001 Ovidiu Predescu <ovidiu@cup.hp.com>
994 * sendmsg.c: Added __objc_msg_forward, a hook that allows external
995 libraries to provide a function that returns the real forwarding
996 function. This can alleviate problems __builtin_apply() and
997 friends have on various platforms. (Solution suggested by Helge
1000 * objc/objc-api.h: Define __objc_msg_forward.
