I think this class should probably be dllexported. It's possible that mingw
looks at class visibility as well as dllexport attributes when deciding
whether or not to expor tthe RTTI for classes, but I'm pretty sure clang
doesn't. We could add that check for compatibility. Is there a compelling
reason to not use dllexport on the entire class here?
