This will take a little work, but perhaps it's not so bad.  off_t is
checked for in configure.  It needs to be propagated where it occurs in the
sources, e.g. in an .st_size member, instead of being assigned to longs (I
don't think that happens much anyway, but I could be wrong).  For printing,
one of %lld or %qd will probably work; there's already a test for %qd in
the rlim_t test in configure, which can be made more general.  ino_t isn't
tested in configure so probably needs adding in the same way.

I already have several things to finish off, so maybe someone else will
feel like looking at this first (although maybe hell will freeze over while
I wait :-)).

I have no idea how to do this.
