Don't cast function pointers; calling functions via pointers of incorrect types is not guaranteed to work. Instead, define the functions with the desired types, and make them cast the incoming parameters. Or define wrapper functions if the return types don't match. really_exit_prog wasn't being used outside src/dialogs/menu.c, and I had to change its parameter type, so it's now static.
OVERVIEW OF BFU
===============
BFU is the text-mode user interface used by ELinks. It builds dialogs,
widgets and menus on top of the window system implemented at src/terminal/.
