That's what I thought.  And, normally, we avoid patches that paper over 
problems.  So, I would ask that Eric figure out where it goes wrong, and 
then fix the real problem, even if that fix turns out to be "remove use 
of TYPE_{MIN,MAX}_VALUE" throughout?

I'd be OK with a papering-over fix for a release branch if we don't have 
time for a better fix -- but we should be fixing things correctly on 
mainline.
