That's why you need a diagnostic.

That's not the same as forcing a cast that makes the code less portable.

1. ptrdiff_t is a derived type.
2. ptrdiff_t is not guaranteed to be large enough to hold a pointer,  
only to hold the difference between two pointers to the same object.  
In a segmented architecture that's not necessarily large enough to  
hold a pointer, and the same is true for size_t.
