                     33:  * to add support for wide characters
                     34:  * Changes:
                     35:  * - Add a compiler variable HAVE_WCHAR for wide character only code
                     36:  * - Add a pointer to liked list of non-spacing characters in __ldata
                     37:  *   and the macro to access the width field in the attribute field
                     38:  * - Add a circular input character buffer in __screen to handle wide
                     39:  *   character input (used in get_wch())
