User update:
You said php4 uses signed integers, so please explain that:
// - - - - - - - - - - - - - - - - - -
list($x) = sscanf( 'ffffffff', '%x' );
printf("%x<br>",$x);
$x = pow(2,32)-1;
echo $x , "<br>";
$y = ( $x >> 16 ) & 0xFFFF ;
$x &= 0xFFFF;
printf("%x%x<br>",$y,$x);
// - - - - - - - - - - - - - - - - - -
Result:
7fffffff

This is not weird, PHP's int are signed integers. 0xac00000 is too large for that.

I've tried this:
list($x) = sscanf( 'ac100000', '%x' );
printf("%x",$x);
And I got "7fffffff", weird.
