Since it's unsigned, all 32 bits are used for a number (and bit 31 does
not represent whether the value is positive or negitive). The 32 bits
are stored as 4 bytes which are (with Intel processors) in order from least
significant to most significant. So this should work - just pass it the
four bytes.

function ulong2int(integer a, integer b, integer c, integer d)
        return a + (256 * b) + (65536 * c) + (16777216 * d)
end function
