Lester,

It is unlikely you'll be able to get g++ to link with Microsoft's C++
object files -- they use different name mangling schemes.  The common way
of linking different flavors of C++ is to wrap C++ functions with 'extern
"C"' declarations.  This will start to get ugly once you decide to
interface instance functions, etc.
