Well - Chris Ball's changes to thr-posix.c.  It's basically bug fixing I
think.

Is because you want to port only single bug fixings to 2.95.4 that you ask
?

Ok - then here are precisely the changes which would be nice to port to
2.95.4 (from the libobjc ChangeLog):

Sun Aug  6 22:51:16 2000  Ovidiu Predescu  <ovidiu@cup.hp.com>

        * thr-posix.c: Integrated Chris Ball's <cball@fmco.com> changes to
        improve the Posix thread support for Objective-C.

Thu Sep 23 07:19:12 1999   Chris Ball <cball@fmco.com>

        * thr-posix.c (__objc_mutex_deallocate): made deallocate work.

2001-03-14  Nicola Pero  <n.pero@mi.flashnet.it>

        * thr.c (objc_thread_add): New function.
        (objc_thread_remove): Ditto.
        * objc/thr.h: Declare them.
        * libobjc.def: Mention them.

Wed Jan  3 00:49:10 2001  Ovidiu Predescu  <ovidiu@cup.hp.com>

        * sendmsg.c: Added __objc_msg_forward, a hook that allows external
        libraries to provide a function that returns the real forwarding
        function. This can alleviate problems __builtin_apply() and
        friends have on various platforms. (Solution suggested by Helge
        Hess.)
        
        * objc/objc-api.h: Define __objc_msg_forward.

The second one allows us to use external libraries to do a more portable
forwarding.  The first one allows us to add and remove threads without
tricking inside the runtime and that helps people running gnustep base on
windows.
