Yea that is how it works, I think SET also pointed that out.
I do use c++ a bit but never had occasion to overload the standard
operators- just class operators.  But my impression was that to
overload it had to be datatype::new(sizeof(datatype)).
In otherwords the operator overloaded for a specific type.
I agree recompileing the library is not neccesary but
I'd still look at the library code to make sure I wasn't missing
anything that could (and probably would) come back to haunt me.
