Btw, you can get real differences from this. It's extremely uncommon, but
try it:
#define A 0x80000000
#define B 2147483648
int a(void)
{
return A == B;
}
int b(void)
{
return A+A == B+B;
}
and see how one of them is false in 64-bits, even though the numbers are
"the same". Things like this can happen with numbers that are used in
macros.
