I tried that but it does not work. For example compiler generatd data
symbols like the module info or the vtable don't get exported even if
the class is declared as "export" Also the tls storage does not work
with threads across dll boundaries. And a lot of other stuff. I consider
dll support working as soon as phobos is a shared dll.
