Hi All,
There were some messages/questions that were only on the list (I get
the digest version), so I appologize for not responding more promptly. I
did want to respond to people and get a final resolution on zsh.

I'm willing to handle issues with zsh, and in particular, this port of
zsh. As I've said, I really enjoy hacking on it, and I feel it's a shell
worth of inclusion in Cygwin. Why else would I have offered it? (well,
besides the fact that I'm a bit loony, but that's completely besides the
point... :)

Funny you should mention that. Actually, only the Zle modules cares
about screen attributes and control, and it is it's own terminal manager
(using termio for the line control). It does link with termcap, but it's
a static link, so no runtime needed, really. Also, there doesn't appear
to be a need for libintl (at least I didn't see it in any of the links).

Now, as to the use of O_BINARY. Is it the general concensus that this
change should be investigated before the package will be accepted or
would people like to give it a try while I experiment with it?
