Please do not remove any code protected by COMPAT_43 which provides any of
the functionality listed on either of the following two standards document
references:

        http://www.opengroup.org/onlinepubs/009695399/basedefs/termios.h.html
        http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap11.html#tag_11

(Yes, I know that this code should not be inside COMPAT_43 protection, but
as far as I can tell, no on has disentagled it).
