        Add a forward declaration of `struct sigcontext' to avoid a
        gcc warning inside <signal.h>.  This is needed since our
        `#define sigcontext_struct sigcontext' hack breaks the Linux
        headers a bit -- it means that an earlier forward declaration
        of `struct sigcontext_struct' won't prevent this warning.
        Also add an XXX comment about the code being duplicated three times.
