      Right. A simplistic solution would be:

      if (xp->xp_context == EXPAND_FILETYPE)
      # ifndef UNIX
      /* don't assume glob() works, syntax should have nearly all filetypes */
      return ExpandRTDir(pat, num_file, file, "syntax");
      # else
      return ExpandRTDir(pat, num_file, file, "{syntax,indent,ftplugin}");
      # endif

      Can you think of something better?
