Sorry, my bad. The name mangling suddenly works now. Didn't figure out what
went wrong.

About your local patches, can you publish them somewhere?

The virtual inheritance part, I've traced dynamic_cast, and found it quite
complicated(single inheritance, multiple inheritance, virtual inheritance).
As it's needed for a basic header <iostream>, I think I can start working
on it.
What do you think?
