I never got that patch to work satisfactorily for me either.

Adam posted a patch for (nearly) current CVS version of gdb
to this list recently, and this patch has been submitted for
inclusion in gdb.  This patch works fine for me ... the
problems I have with the latest gdb patched with it are,
as far as I know, general problems with the current gdb code
rather than anything objc specific.

You could look in the mailing list archive and grab the patch.

If you can't find it there you could ask me or Adam to email it
to you.

Or perhaps the patch has even made it in to the gdb CVS already
(though I doubt that).
