* systty.h (HAVE_LTCHARS, HAVE_TCHARS): New macros; define them if
we have those structures, but *don't* define them if we have
TERMIOS, whose functions take care of those parameters; that
screws up AIX.
(struct emacs_tty): Test those symbols, instead of the ioctl
commands.
* sysdep.c (emacs_get_tty, emacs_set_tty, new_ltchars, new_tchars,
init_sys_modes): Same.
