Surely. But the point is that you can use these steps to relatively easily 
make a working thin binding. You then write your intended interface (the 
thick binding) by directly using the thin binding in Ada. That should work 
without stressing the Ada compiler and causing weird failures. (That's how 
the best Ada bindings are built; you have a direct thin binding and then a 
thicker binding that makes the thin binding more appropriate for Ada by 
introducing exceptions, generics, default parameters, sensible Ada naming 
(no camel case!), and so on.)
