Comment 1 for bug 661530

pcltar.func.php contains the following code

      // ----- Check the path length
      if (strlen($p_filename) > 99)
      {
        // ----- Error log
        PclErrorLog(-5, "File name is too long (max. 99) : '$p_filename'");

I am unsure whether changing this will have adverse effects, but it is worth a try...
