Certainly not the right tool here. It appears that clang seems to work
quite well for both C and C++.

That's likely because the parser requirements grow with the tool itself.

I think it really makes sense to do this. A suitable level of detail for
all generators may not be immediately obvious, but should be doable.

Please do. I'll ask over at the Cython-users list to see if others have
something to contribute to this discussion.
