I'm not sure if this is a bug or a feature.

But I find the following differences between *nix and cygwin on access
permissions of 'ls'

Test case:

$ mkdir -p dir1/dir2
$ chmod 700 dir1

<switch to a another non-root/non-admin user>

$ ls -d dir1
dir1  [both Linux & Cygwin]

$ ls dir1
 ls: cannot open directory dir1 Permission denied  [both Linux & Cygwin]

$ ls -d dir1/dir2
ls: cannot access directory dir1/dir2 Permission denied  [Linux]
dir1/dir2 [Cygwin]

No acl's beyond the standard ugo posix permissions are set on either system.
The Cygwin user only belongs to the 'None' and 'Users' group.

In particular, why is a non-privileged Cygwin user able to look over a
blocked directory further into a file tree?
