Interesting. I would have expected NetBSD/alpha to manifest the same
symptoms, but a quick check shows that time_t is 4 bytes there. That'll
teach me that all LP64 platforms are by no means created equal ;) In any
case, thanks to ben@ for fixing this, and to you for pointing out that he
had done so. Screen is working just fine now.

Now if I could only figure out what the root cause of the "sleep sleeps
forever" bug, but I have no idea where to start looking for that. I've only
experienced it once, but its disabling enough to a system that I'd rather I
(or someone) find it before it finds my sparc64 again...
