I wan't really clear on this one: PHP _does not support unsigned ints_

Generally, it support integers from -2147483648 to 2147483647

PHP 4 handles number-constants smartly. I.e., when a number is out of range of 
integers, it will be auto-converted to float.

var_dump(0x80000000) -> float(2147483648)

While | requires int-arguments, and because it cannot convert float(2147483648) to 
int, it will take MAX_INT instead.

That abs(MINIMAL_INT) bug, is a bug which I fixed yesterday (coincidence...)

The 0x80000000 | 0; : apparently 

(int) 2147483648.0 => -2147483648
This IS a bug, because it should have been INT_MAX (2147483647)

I'm currently trying to sort that out. By the way, do not put multiple bugs in one

$qq = 0x80000000;
echo $qq;  //2147483648  ok
$qq = 0x80000000 | 0;
echo $qq;  //-2147483648  ???
echo abs($qq);  //-2147483648  ???
echo $qq * -1;  //2147483648
