So if you want aarch64 to be compatible with aarch32, you need to
define __WORDSIZE_TIME64_COMPAT32.  If we don't want aarch64 and
aarch32 to be compatible at all, then we can drop this patch or if you
don't want LP64 and ILP32 to be compatible either.


Or go the other way like s390 and use the LP64 layout for ILP32.

"And now for something completely different."


It was an agreement that we don't fix Y2038 issues specifically, as
there will be general fix.

As far as I understand this, it is not a Y2038 issue because it affectscurrent systems using current dates. It's a separate bug IMHO.
