Note that pragma Unchecked_Union is in Ada 2005, and several compilers
already support it. But if you're not using one of them, you can't do it
this way.
Our experience with Claw was that there wasn't many cases where you really
needed a Union. Most of the time, careful declarations avoided the need.
When we really did need a Union, we used Unchecked_Conversion. YMMV.
