Wait a minute...
Look at a simple case,
(this is binary folks)
a = 1 1 1 1
b = 0 1 1 1
if (a & b & 0x8) { ... } would be false, but the addition of a and b would
result in a carry (overflow).
or this case:
a = 1 0 0 0
b = 1 0 0 0
if (a & b & 0x8) {...} would be true, but the addition of a and b would
still result in a carry (overflow).
Maybe I'm just too tired to see straight.
