So from the reply below I take it hasn't been fixed/worked
around in a snapshot. But my experiments show something has
changed. With the snapshot I can create a file, with the standard
1.7.9 dll I can't.

In my case that it true, chmod fails.

This is by design here. IT wants it that way.

I am willing to try to hunt it down. What do you want me to check?
Hm, it seems something really has changed, I can't reproduce the
problem at the moment. I can create a file, delete it but can’t
change permissions. The latter breaks d2u:
$> touch /u/blubb
$> d2u /u/blubb
dos2unix: Failed to change the permissions of temporary output file /u/d2utmpaF6gvB: Permission denied
dos2unix: converting file /u/blubb to Unix format ...
dos2unix: problems converting file /u/blubb
$> rm /u/blubb
rm: remove regular empty file `/u/blubb'? y
Is there anything in the snapshot that could explain it? Or
did I mess up everything here? Confused...
Well, I just cross checked. Reinstalled 1.7.9 and the problem
is back. So the snapshot seems to have fixed it. That is,
CYGWIN_NT-5.1 p01080268 1.7.10s(0.253/5/3) 20111017 18:26:05 i686 Cygwin
Didn't try the latest. With the snapshot it behaves like 1.7.7 apparently.
