>Description:
When _XOPEN_SOURCE_EXTENDED is defined, ncurses.h conflicts
agains stdlib.h.  ncurses.h checks whether __wchar_t macro is defined,
but FreeBSD's __wchar_t isn't a macro but typedef.  So we need to
change the condition to defined(_WCHAR_T_DECLARED).


>How-To-Repeat:

try compile the following: (which is digested from Python aclocal.m4)

#define _XOPEN_SOURCE_EXTENDED 1
#include <stdlib.h>
#include <ncurses.h>


>Fix:
