If you are working on a local drive, use a snapshot (there have been bug
fixes on this front to make the link count reliable).  But if you are on
a shared drive, where nlink is 1, it is because there is no efficient
way for cygwin to compute the link count, so you can no longer
use the link count as an optimization for finding leaf dirs - you
will manually have to stat every file in a directory with a link count
of 1 to count the number of subdirectories yourself.
