Again. The fact that *you* haven't doesn't mean that others are
in the same boat. A maintainer's job involves exactly that kind
of deliberation :)

(I'd bet that Stefan's hardware is still 32 bit :)

So basically it reduces to whether the Emacs project wants to
support 32 bit systems (currently, the answer seems to be "yes")
and what to do about time_t when yes.
