The patch looks good and applies cleanly now,

Some notes to look into after this patch:

 - can you provide a testcase for the problems caused by the wrong
   time_t usage?  A patch to xfstests would be perfect, but if you
   have a raw testcase I'll vounteer to wire it up.
 - why do we wrap both ctime and ctime_r?  Currently xfsdump isn't
   multithreaded so we shouldn't need it.  But if the parallel
   dump/restore ever gets merged from IRIX we need to get rid of the
   plain ctime calls.  (Btw, are there any plans for the parallel
   dump/restore port?)
