I'm surprised Greg didn't mention the AFC (Ada Foundation
Classes) which is their binding to the MFC.  I would think
with that ability it would be relatively simply to interface
between the two.  Assuming the bindings contain the class
in question.  Even if it were a user defined class, you
could at least follow their examples to accelerate the
interface process.

Of course, you have to buy the right level of their tool
to get it.

We have some customers doing this.  I believe the main trick is to declare
C++ methods as static at the interface point.  This principally turns off
C++ name mangling, so the Ada side knows what the function name is.
