That doesn't mean anything. It might as well be written in Ada and
pragma Export everything to meet the "lowest denominator" at the C
level. It might as well be written in assembler. And so on.

As a demonstration that this can be a reasonable approach, the YAMI4
core library was written in C++ (to benefit from namespaces,
encapsulation, and access control), but exports its interface in terms
of extern "C". This interface is used as a basis for the Ada part.
Technically, exactly the same approach might have been used in the
Win32-Claw stack. Without you knowing about it. ;-)

I don't claim that this is actually the case, but this is a)
demonstrably possible and b) it even makes perfect sense from the
engineering perspective.

And in fact, the following might be an answer:
