Under W7 SUA is still using its own brew of symlinks which is equivalent
to the default Cygwin symlinks:  A file with the SYSTEM DOS attribute
set, a magic cookie ("IntxLNK\1"), and the target filename.  Cygwin 1.7
can read Interix symlinks.  Of course, due to the different directory
tree layout (/cygdrive/c ==> /dev/fs/C), absolute paths in Interix might
point into nirvana under Cygwin.
