Yes, I changed my passwd and group files so that in /etc/passwd
`Adminstrator' (RID 500) is mapped to `root' (UID 0) and in
/etc/group `Adminstrators' (S-1-5-32-544) is mapped to `root' (GID 0).
My `corinna' user entry in /etc/passwd contains contains GID 0 as
well, so I'm member of the `root' group in Cygwin (and member of
the `Administrators' group in NT of course, too). I did this on
both systems for convenience.

However, this shouldn't result in the different behaviour.
The usernames are identical but the RIDs on both systems are
different (1000 and 1003). A `ls -l' on an already existing file
shows according to that:

$ cd //cvaio/corinna
$ ls -l x.c
-rw-rw-r--   1 1003     root         1132 Nov  7 16:55 x.c

while the touch uses the correct SID of the source system:

$ touch foo
$ ls -l foo
-rw-rw-r--   1 corinna  root            0 Dec 13 23:27 foo

Could you please send me (to my personal account) straces of
`touch foo' and `chmod 666 foo'? Gzipped would be nice.

Would you mind to use a special test DLL later, potentially?
Perhaps the current trace output isn't sufficient to find the
reason.
