Re: 64 bit addressing

Hopefully when 64-bit tasks become a real possibility for developers, there will be compiler options to complain about pointer-to-int conversions even if there is a cast, or to ignore many kinds of casts, or whatever. Options that could be turned on to help the conversion, then turned off again (probably).

Fortunately, there already is such a warning:

void *foo(unsigned short x)
{
return (void *)x;
}

foo.c: In function `foo':
foo.c:3: warning: cast to pointer from integer of different size

Presumably this would take effect for the congruent case of a 32-bit int being casted to a 64-bit pointer.
