We try to rewrote code in universal manner, but old curses code 
in wineconsole had many hacks and we are changed some parts 
anywhere.
I need to accept this patch for detecting ncursesw. Then we can 
send next patches for unicoding.
I do not know about function redefining, there are incompatible 
function's arguments (cchar_t vs wchar_t) and it needs various 
code...
As I see we need use libncursesw as the main curses library, and 
have old curses support for compatibility with some old systems.
