cygwin 1.7.5, 'id -ng' fails when /etc/group is a symlink

Yes, tremendously!  And here I thought I had done my homework ...
obviously I failed.
I was all over that section reading up on fstab and the changes in the
CYGWIN environment variable options too ... and yet I still missed it.
Sorry for my oversight.  Thank you for pointing this out to me! :-)

Now that I have "read" the documentation, I understand.  And, yes,
the native NTFS symlink method does indeed work in Windows 7.
Unfortunately, that will not help in my WinXP environments.  However,
native Windows shortcuts (.lnk files) will work for my purposes in
both OSes.  And, since the documentation for the special files in /etc
states that "These file are read using native Windows NT functions",
I presume that method would be acceptable in this case - I realize
that this is somewhat unorthodox, however.

Corinna, I thank you kindly for the assistance!
