Ok.

Ok. 

I suppose this could be a standard, defining how various C statements
get translated into Ada, but I suspect that would be far more effort
than it is worth. So we'll just have to trust AdaCore to do a good
job. Since they are motivated by customer needs, I'm not worried :).

That's not important. You only need to generate the Ada code once
(well, once each time the C code changes); then you can use it with
any compiler. So only the tcladashell maintainer/developer needs
-fdump-ada-spec.
