And you should have an error, especially is you pass object from 
one side to the other.

typeid won't match (which will create a mess in the runtime), and 
worse, struct layout may not match (hello memory corruption).

If the problem is that big, we can still have a -noexport flag or 
something, but that doesn't seems really safe to me.
