Yes, the idea is for GCC to diagnose casts between pointers and 
wrong-sized integers.

Warning about integer conversion is controlled by -Wconversion. However, 
that GCC option generates far too many false positives for useful code, 
so I don't recommend it. I just tried -Wconversion on Emacs master and 
got over 10,000 bogus warnings. Changing Emacs to pacify -Wconversion 
would cause more trouble than it'd cure.
