Do impossible Ada implementations exist? ;-)

I think if you're after practical portability, the PDP-10 doesn't
matter to you.

According to http://www.inwap.com/pdp10/hbaker/pdp-10/Byte.html, the
smallest individually addressable storage unit is a bit, so with a
common definition of a byte, it consists of a single bit. ;-)

If I were writing an Ada compiler for the PDP-10, I would probably
choose Storage_Element'Size = 9.  IIRC, the GCC porters are doing a
similar thing (CHAR_BITS == 8).
