This is _not_ what rep spec say. They say how to lay out the bits in
memory, not how to access them.

Some compilers do "what you want", but there is _no_ guarrantee in the
language for this.

If you need a 16 bit access, use assembly code. Wrap it up in a
low-level Ada subprogram, to make it easy to use.

Yes, it feels inefficient and inelegant, but it is the best approach.
