Hmm. I'm just re-running the (latest) setup.exe - what else should I do ?
In c:\cygwin\bin I found a cygwin1.dll.new with version 1007.9.0.0 as
well as one with the right name, version 1007.7.0.0.

If I swap to using the 1007.9 one by changing the names, bash stared
from the command line just seg faults...

tchiverton AT EV34:tchiverton$

This does not happen if I run Bash again from CMD (!)
Though I can now run ls and get output !

Did I manage to get a broken update at some point then ?
Can I recover, apart from deleting c:\cygwin and reinstall ?

I can replicate by just opening a Windows command prompt, run
c:\cygwin\bin\bash and then use '/bin/ls' as PATH seems wrong.
I normally use a short cut in the start menu that has a 'target' of
"C:\cygwin\bin\rxvt.exe -geometry 100x50 -sl 1500 -fn "Inconsolata-14"
-bg black -fg grey -sr -e c:\cygwin\bin\bash --login -i" though.

Nothing. "ls -la .[tab]" works as expected though.

Nope.
I looked in them, and they seem OK.
Running 'id' doesn't produce output either, so I guess that is why
it's not in the check output.
