hmm - I think you meant _XOPEN_SOURCE_EXTENDED

If your application is simple enough, it works without that.
There are a few places where the difference between cchar_t and chtype
is exposed in curses.h (the WINDOW struct for example).  As long as
you use things like addstr() and printw(), it does not matter.

This is a difference between libncurses and libncursesw: the functions
that accept a char* string expect a multibyte character string (for 
example UTF-8) rather than 8-bit characters.

As I recall your example, it should work.
