As an aside, this has nothing to do with strictness. The reason is  
that FPC and ObjFPC mode allow function overloading without the  
"overload" keyword. So the compiler sees the above as two overloaded  
functions (one public, one private) as opposed to the interface and  
implementation declaration of the same function.
