I am downloading 6.3.1 right now. Unfortunately I'm really under
a crunch right now and may not be able to get back with you for a week.
An initial look at this code tells me that it's one of the fewest
changed routines in there. The only change is how the connection
handle is retrieved. I'll try to build and test 6.3.1 on my machine
at home today.
