   /* Modified by Ruibiao Qiu <ruibiao@arl.wustl.edu,ruibiao@gmail.com>
    * to add support for wide characters
    * Changes:
    * - Add a compiler variable HAVE_WCHAR for wide character only code
    * - Add a pointer to liked list of non-spacing characters in __ldata
    *   and the macro to access the width field in the attribute field
    * - Add a circular input character buffer in __screen to handle wide
    *   character input (used in get_wch())
