The header <ncursesw/ncurses.h> defines the get_wch(3) function only when `NCURSES_WIDECHAR` is defined. This define is actually getting set in the same header file, but only in case `_XOPEN_SOURCE` is defined and has a value of 500 or higher. As we already have the precedence of defining `_XOPEN_SOURCE` to a value of 600 in some other files, simply define it to the minimum required value of 500 in "cfdisk.c". This silences a warning for `get_wch` being unknown.
