It is only a hint. And Typecasting pointer <-> integer will always trigger
such a hint. It is usefull for ppl compiling on 32bit that they need to
look at thing carefully if it is what they intended. Typecasting a pointer
to longint on a 64bit target will give a warning instead.

But this hint/warning is independent of the first question about
integer/cardinal sizes. Please stay to the topic of the thread.
