They are not clobbered, they are now actually showing the correct POSIX
permission bits based on the file ACL by default.  In Cygwin 1.5 the
default was not to use the ACLs on network drives  and to fake the
POSIX permissions (CYGWIN=nontsec).  If you want to know why the ACL
results in d---------+ permissions, I suggest to take a closer look
using getfacl.

I strongly suggest to read the new and improved 1.7 User's Guide,
especially stuff like
