Hmmm - I was able to look at this for 30 minutes during lunch.  Not enough
time to get a handle on it.  Don't see any output on my scope on GP2.

GP2 is also the TOCKI input.  Maybe this thing is defaulting to using TOCKI
and overriding the TRIS comand.  Looks like it defaults to a TOCKI input.
Could the compiler possibly be this dense?  Ans:  YES.    I'll put a scope
back on it tonight.......
