/* 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())
