   Changes with APR b1
   
  +  *) Change the ordering of the apr_lock implementation method to
  +     better match what's done in Apache 1.3. The ordering is
  +     now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
  +     [Jim Jagielski]
  +
     *) Improve detection of the INT64_C macro to prevent problems
        with HP-UX's ANSI C compiler.  PR 8932.  [Justin Erenkrantz]
