Forgot to mention ...

I also have a patch to add support for "private extern" and while 
libdispatch can use them, it looks like that it is deprecated in favor 
of the visibility attributes so I don't have plans to commit it.

I started patches for pascal strings and writable strings but they cause 
segfaults and are also officially deprecated so I won't be doing those 
either.

Other than those, Apple has some bug fixes and support for more warnings 
that are also available in clang. Not sure if I want to spend more time 
in gcc though :-P.

Regards,

Pedro.
