If all we go by is the standard, even a floating-point time_t is
permitted (though our code won't work with that...).

Yes, it breaks a lot of software and is pretty rare.  But I think it's
used in at least some versions of DJGPP, a modern 32-bit platform; see
<http://www.delorie.com/djgpp/doc/incs/sys/djtypes.h>.  Maybe DJGPP
plans to still be with us after 2038?
