I agree with you, but why create many definitions in many cpp files? Except
of that, you can use #ifndef at definitions too (it is called "conditional
compilation").
 Anyway, if i remember well we were talking about definitions included in
the header file, not external source code files (where as i said we can use
conditional compilation too).
