    I can tell you what cannot happen. You absolutely can't consider
    ideas like using '__u32 val[2];' and accessor macros, long long or
    whatever type the platform uses for __u64 has different alignment
    constraints than the '__u32 val[2]' array thing would.

    I believe there is a way to work around this by using the
    __extension__ keyword when defining the __u64 typedefs. Someone
    should try playing with that. But this is only going to work when
    the compiler is GCC.
