Thanks Simon. He found the library elsewhere on his machine & copied it to
where GNAT wanted it. Gnatmake now runs.

The problem now is a portability issue.

I have the declarations:

   type word is mod 2**48;

...

   type field_of_16_bits is mod 2**16;

   type Q_part is new field_of_16_bits;

   type Q_register is
      record
         C_part, I_part, M_part : Q_part;
      end record;
   for Q_register'Size use KDF9.word'Size;

And this is fine in Intel.  But on PPC, we get the error:

    92.    for Q_register'Size use word'Size;
                                        |
        >>> size for "Q_register" too small, minimum allowed is 64

It's puzzling that the compiler refuses to give Q_register the size that it
happily gave to word.  (The aspect clause is there to support unchecked
conversions between the word and Q_register types.)
