Hmmm... you're explanation may be right, but I find it hard to believe that
relates to my problem, for:
1. The exit code is not 0
2. An ls -R on my C: also yields nothing

That sounds plausible ;)

I thought the non-cygwin sshd apps were just making use of cygwin in a
custom way, without the need of installing cygwin itself. At least, when
they get installed, you end up with some command-line tools, among which a
cygwin dll. That made me assume these apps are just a partial cygwin with
some handy auto-configuration. But your remark makes me think I see that
wrong.
Still, mustn't I be able to launch a shell with the cygwin.bat that comes
with a fresh cygwin install? And subsequently be able to call any command
(like ls, man, ...). That's what I'm able to do on my XP box anyway.

I tried both "SET CYGWIN=tty" and "SET CYGWIN=notty" from my command prompt
and then call bash (within the same cmd session of course). This does not
make any difference. Should I try to force the tty setting in another way?
