Using >> normally shifts bits to the right x number of times, where x
is specified by the programmer. As an example, 0x40000000 >> 8 yields
0x00400000. This makes me wonder... why doesn't the same thing happen
with 0x80000000 >> 8? The number it yields is 0xff800000 - not
0x00800000. The following script better demonstrates this:

<?
echo sprintf('%08x',0x40000000 >> 8)."\n";
echo sprintf('%08x',0x80000000 >> 8);
?>

Anyway, any ideas?
