There is no PORTABLE way. Most compiler vendors however will tell you what you
can do to avoid this. The DEC Ada compiler, if memory serves, treated any 
variable associated with an address clause as "volatile" for the scope of the
address clause. "Volatile" addresses are not optimized into registers. Again,
this is DEC Ada only. Check your vendor docs.
