I'm sure Microsoft provides many different forums for this. Look at 
their website. This is definitely not the right place.

As you note, VC++ and G++ use different vtable layout, and the chances of
these two being compatible anytime in the near future is infinitesimally
small. You could ask Microsoft to provide a G++ compatible vtable layout.
They're supposed to be good at listening to customers ;-)

You cannot mix VC++ with GCC, Sorry.

The hope in the near term is to use COM objects and that should work. The
work on GCC to support COM objects from C++ is being worked on right now.
The other (non)solution is to use "C" linkage, but that pretty much defeats
the purpose of using C++.

Mumit
