> host operating system : sco3.2v4.2

Here's the patches I used to apply to zsh when I compiled it for
this version of sco.  The first change allows zsh to accept tty
changes via things like stty.  It does have the effect of allowing
all program to change the tty settings (even the background ones),
but that's the best SCO can do since they have a bug in their
library.  SCO 5 doesn't have this problem, so it would have to
be made conditional for only older versions of SCO, and I never
figured out how best to conditionalize this (because we got rid
of SCO from my machine).

The line numbers will be a little off, since this patch was
last applied to beta 14.
