Yes.  And with vanishingly few exceptions, this is wrong.
In my experience you've probably got a program that won't
run on a 64-bit machine.  You probably meant to use size_t
instead of int or something.

For those cases where you really REALLY know what you are
doing, "x = (void *)(size_t)y" will not warn.
