See the snapshots.  The next major Cygwin release will be able to read
native NTFS symlinks and treats them as symlinks.  However, it's not
planned to utilize native NTFS symlinks when creating symlinks in
Cygwin.  This has two reasons.

One is the above mentioned non-sensical restriction that only users with
a special privilege may create native symlinks.

The other one is that native symlinks on remote Vista shares are not
implemented transparently to non-Vista client machines trying to access
a Vista share.  An XP client can not access the target file of the
symlink by opening it.

Frustrating, isn't it?
