Please read C++ FAQ, or better yet, Stroustrup's book, on why you cannot,
in general, mix-and-match code from different C++ compilers.
To be able to mix C++ code between two compilers, the compilers must use
the same/compatible Application Binary Interface (ABI) that dictates how
the objects are laid out in memory, and other (secondary) issues such
as name mangling and so on.
The only compiler that *may be* C++ ABI compatible with MSVC is
Metrowerks (http://www.metrowerks.com/); GCC is not, and is unlikely
to be in the near future, ABI compatible with MSVC.
This hopefully also answers the question that you asked in your private
email regarding using dlltool on VC++ C++ symbols.

Mumit
