Worked for me on a self-built dll! Thanks for an awesome patch.

Now, what would be really cool is if the link count of directories with
mount points could be updated, to match the fact that readdir can now see
mount points:
$ cd /usr/
$ ls -dl .
drwxr-xr-x+ 21 eblake Domain Users 0 Mar 1 09:22 ./
$ mkdir /cygdrive/c/cygwin/usr/lib
$ ls -dl .
drwxr-xr-x+ 22 eblake Domain Users 0 Mar 1 09:26 ./
Oops - see how the link count changed from 21 to 22 when I had a physical
backing directory? find (and any other tool that optimizes a recursive
search to look at (link count - 2) subdirectories and then quit) might
get confused by the fact that the number of subdirs given by readdir is
no longer consistent with the link count.
