Thank you for this report, but I'm going to NAK this patch. I will take
a closer look at this tonight and I will make a new patch for this.
First to take care of the FIXME that's just before the first change
below and secondly I'll see if it isn't better to change has_ir to an
int: I don't like using ~0 like this.
So expect to see a new patch later today.
Regards,
Hans
