State-Changed-Why:
    This patch looks fine to me David.  I will post it to gcc-patches@gcc.gnu.org (CC'ing you) in the proper form for review by the [lib]objc maintainers.  Here is a test case (we normally like them in addition to patches and I will include it):
    #include <objc/hash.h>
    #include <objc/objc-list.h>
    Add this flag to see the problem when installed from FSF tree: -Wsystem-headers
    FYI, I'm closing this PR before commit since strictly speaking this
    problem only appears to affect non-FSF installs.  I will include
    some commentary with the patch.
