32 * Colors in ncurses 1.9.9e do not work properly since foreground and
33 * background colors are OR'd rather than separately masked. This version
34 * of dialog was hacked to work with ncurses 1.9.9e, making it incompatible
35 * with standard curses. The simplest fix (to make this work with standard
36 * curses) uses the wbkgdset() function, not used in the original hack.
37 * Turn it off if we're building with 1.9.9e, since it just confuses things.
