Anything that uses the old-style (sgtty) terminal driver.

Most of the other bits of code conditioned on COMPAT_43 are binary
compatibility with 4.3 system calls for Suns and VAXen, and really
could be done without for i386es, since those 4.3 system calls were
never used on the i386 platform (having been superseded before the
i386 port was done).
