Since these reparse points are implemented with a special type of 
symlink, open() with O_NOFOLLOW should fail with such an object.

It's been a while, but I'm nearly certain I implemented O_NOFOLLOW and 
O_NOLINKS entirely in filesystem-independent code. So the answer should 
be the same for all filesystems.
