Let me add my voice to the chorus that says those still using
eleven-year-old versions of zic deserve to lose.  And let us not
forget that that the compiled file format is backward-compatible, so
even if these users have ancient systems that they can't replace, they
can compile the data files on a newer machine and copy the zones they
need to their older device.
