  Robert, 

  I'm not sure whether any detailed technical explanation is 
  of particular value.  My opinion is based on:

  1) My familiarity with the architecture of the 8051. It is
     not simply an eight-bit microprocessor. Notice that I 
     explicitly did not rule out the possible value of
     Ada for more conventional eight-bit processors.

  2) I know a little bit about Ada.


  3) I know a little bit about GNAT (though not as much as you).

  My challenge still stands. I do not believe the 8051 is an appropriate
  target for Ada.  Creating an Ada compiler from scratch
  for this architecture would be daunting. Porting GNAT?  Well, I
  continue to be skeptical.  If it could be done, there is a huge
  market opportunity.  It is one of the most widely-used microprocessors
  in U.S. industry. 

  I will not believe it until I see it.  I do hope someone will prove
  me wrong.
