    [refer]: Fix code style nit.
    
    * src/preproc/refer/label.ypp: Give the anonymous `struct` types used
      for `dig` and `str` names, so that they can be passed to a template
      function C++98-conformantly.  Lamely, apply an `_s` suffix to the
      object names to create the type names.
