                        -----------------------------------------------------------------
                        conf.h: Added FLOCK_SERIALIZED_ACCEPT to A/UX
                        http_main.c: created FLOCK_SERIALIZED_ACCEPT for
                        systems that need it,  but using fcntl() locking is
                        expensive (esp. running NFS) mod_cgi.c: Cliff
                        Skolnick's read_client_block check mod_userdir.c:
                        If we hit the end of the UserDir list, and we
                        haven't  found a file, return NOT_FOUND; we were
                        returning OK before  with junk in the r->filename

  *** 1,3 ****
  --- 1,14 ----
  +   *) Added FLOCK_SERIALIZED_ACCEPT for those systems, like A/UX,
  +      that need mutex-capability but using fcntl-locking is
  +      expensive. [Jim Jagielski]
  + 
  +   *) Fixed translate_userdir(): return NOT_FOUND when at the end
  +      of the UserDir list (was returning OK and junk in the filename).
  +      [Jim Jagielski]
  + 
  +   *) Added in Cliff Skolnick's read_client_block patch (check for
  +      no reads and break) [Jim Jagielski]
  + 
      *) If there was no default MIME type defined, Apache sent Content-type:
         without a newline, thus swallowing the next header. Changed to send no
         Content-type: at all. [Ben Laurie]
