Not according to that error-message, which says that it's a *long long*
(like in the opening line of the song "American Pie", not in the
 opening line of the Star Wars Episode IV).

In order to have a 64-bit time_t and escape the 2038 problem,
wouldn't time_t have to be at least equivalent to "long long"
on 32-bit platforms where "long" is still only 32 bits?

I for example haven't had any desktops there were less than 64-bit for a while,
but I still have *lots* of 32-bit embedded Linux devices--ranging
from cheap routers to expensive robots.
