X-Patchwork-Id: 76132
Message-Id: <1292770620.493427194@192.168.2.227>
To: "gcc-patches@gnu.org" <gcc-patches@gnu.org>

This patch declares in objc/runtime.h a function (class_ivar_set_gcinvisible)
that existed in the old API and should still exist in the new API (at least until
we review GC if we want to), but that I had forgotten to declare.

It also removes a #define in sendmsg.c that had been added as a temporary hack
during the header reorganization and is no longer needed.

Committed.

Thanks
