Keven,
  Thanks for the suggestion.  Unfortunately, HP_ALIGN appears not to work under
gcc.  Furthermore, the __attribute__ ((aligned(2))) which, in gcc, looked like
it would accomplish the same thing can only set the minimum alignment, so it
can't force int to work on a two-byte boundary.  I'm going with a macro to do
the sum at the moment, but if I'm obviously missing something, I'd be delighted
to hear.

Thanks,
Ted
