Reposting, since noone noticed the patch at the end...

> Hi there,
> I've had a working port of zsh to ZETA (BeOS R6) for quite a while,
> but
> since I'm not (yet) a big user I never managed to publish it. I was
> also too lazy to clean up the small C89 fix required (we require
> gcc2.95 due to the C++ ABI breackage on later versions).
>
> I didn't try but it should likely compile fine on BeOS R5, at least
> with the BONE network stack.
>
> It should also compile without much trouble in Haiku (MIT licenced
> rewrite of BeOS). It will probably need some more library check
> (socket
> in -lnetwork) though.
>
> Some tests still break, but most are due to missing features, and at
> least they don't crash like they used to.
> - BeOS defvs shows all devices as S_IFCHR, including block devices,
> so
> there is no S_IFBLK device in /dev per see.
> - BeOS doesn't have /dev/tty (Haiku does though)
> - BeOS natively uses UTF-8 everywhere, but has an old glibc, so it
> misses some wc*()... I still don't get the point of using ugly stuff
> like wchar anyway.
> - zpty doesn't load yet for some reason
>
> I'll likely have to port over all the bash_completion stuff I
> wrote...
