It would be nice if it was possible just to create aliases symbols in
object files (symbols pointing to the same area). Then, you could create
a tool that would make a C header where the first parameter would always
be a "this", thus emulating the C++ stuff by hand.

It would avoid a wrapper call, because calling the alias would be just
like calling the real thing. Of course, virtual methods wouldn't work.
:-)

Maybe it is even simpler. Look at db.h for enlightenment on C-based
vtables (yes it is ugly, but you want the feature or not?).
