Funny, this pops up again and again.. =)

Maybe this should be in FAQ (if it isn't already there).

Well answer is no. DLL's aren't allowed to have unbounded undefined 
symbols. There is few ways to get this over, see message thread "DLL and 
external symbols" started by me and "DLL vs. shared object linking 
behavior" started by Karl Robillard.
