In at least one place in libc, it is necessary to range check a time_t
value. One most platforms, time_t has the same range as `int', but
on at least amd64, it has a larger range. Any objections to adding
definitions of __TIME_MIN and __TIME_MAX to sys/${arch}/_limits.h?
I could just do the usual check for lossage after casting, except that
in theory time_t could be a floating-point value (but not in reality
in FreeBSD). It seems cleaner to me to have an explicit range.
Cheers,
