It seems so. From a quick test, g++ and bcc32 do return C++ classes from 
extern "C" functions, only MSVC emits an error. I'm not sure whether such a 
function makes sense, though. If you suppress name mangling, presumably 
because two different compilers mangle names differently, what are the 
chances that the object layout will be the same?
