Post this time to the list, the last time I sent it to Kris directly, sorry
for that
Hi Kris

I think that your patch could be better if instead of using the "signed" right
shift operator (>>) followed by a bit mask, use directly the "unsigned" right
shift operator (>>>)

So
((val >> 24) & 0xFF)
would better as
val >>> 24

By the way great work folks
