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?
