* readline.c (rl_save_state, rl_restore_state): Support systems
that don't define SIGWINCH. * terminal.c (_rl_get_screen_size) [__DJGPP__]: Compute the screen width and height using console I/O. (_rl_init_terminal_io) [__MSDOS__]: Zero out all the _rl_term_* variables. Convert to _rl_* naming scheme. (_rl_set_cursor) [__MSDOS__]: Ifdef away this function. * display.c (_rl_move_vert) [__MSDOS__]: Don't use undeclared variable `l'. Use `delta' instead recomputing its value anew. Assign -delta to i instead of the other way around.
