No, you were quite clear, but perhaps my response wasn't. It seems to me
that treating such code as an error is entirely appropriate; a warning
seems inadequate. Why do you feel differently?
If you actually have a legitimate need to do the conversion, and know
something implementation-specific that makes is safer than it is in the
general case, make those facts explicit by using a cast (in C) or a
reinterpret_cast<> (in C++). Requiring something as clumsy and as easily
searched for as reinterpret_cast<> in order to perform such a dangerous
conversion also strikes me as a good idea.
