The other poster is right -- there's nothing to say that the above causes the
compiler to generate 16-bit accesses. When you need that kind of control, you
are better off writing the machine-code insert to do it explicitly, rather than
trying to coerce the compiler to do it the way you want. Sure, you can often
get your compiler to do what you want, until the next release!
