Moreover, this has a problem with "ls -al /cygdrive/z".
The information for ".." is not retrieved correctly.

I think '/cygdrive/z/..' should be '/cygdrive', however,
in current cygwin, it is interpreted into '//VBoxSrv'.

Is this as you intended?

With my patch which stops to treat UNC path as symlink,
'/cygdrive/z/..' returns '/cygdrive'.
