I think sizeof (off_t) should be 8, regardless.

Reason: it will be 8 in the future, and maintainers are likely to
get libtool versioning wrong.  They will believe the interface
hasn't changed, and they maintained backward compatibility, when
in reality they haven't... so the libtool version numbering will
be wrong, and will introduce silent seg faults that will be a PITA
to track.

Better to make the subtle/incompat change sooner (when there are fewer
users, since presumebly they are monotic increasing... and also,
where incompat API changes are more frequent/expected ;)
