37 | * of dialog was hacked to work with ncurses 1.9.9e, making it incompatible | |
38 | * with standard curses. The simplest fix (to make this work with standard | |
39 | * curses) uses the wbkgdset() function, not used in the original hack. | |
40 | * Turn it off if we're building with 1.9.9e, since it just confuses things. | |
