Are you sure?  Isn't there a current _very_ long thread about a current 
'impossible' Ada implementation :-)?  Oops, that's an Ada compiler/tool
set, sorry.

Seriously, shouldn't the Storage_Unit refer to the addressable unit on 
the machine?  For example, on a machine with 32-bit addressing, does the
potential address space cover 2**32 8-bit bytes, 32-bit words, or
256-bit 
cache-words?  I would think most machines are byte-addressable,
therefore
Storage_Unit should be 8.  On machines we use, we have a 16-bit address 
space and can reference 2**16 16-bit half-words.  Therefore Storage_Unit
would be 16 (assuming an Ada compiler existed, HA!), even though 8-bit 
bytes and 32-bit words can be referenced.

Just my thoughts.
