It's exactly what is done by Cygwin. A shortcut created by Cygwin or
U/WIN has a special header format which is sort of uncommon.
Additionally, the R/O attribute is set and maintained by Cygwin and
U/WIN. When a user changes a shortcut s/he has to remove the R/O
attribute first. If that attribute isn't set the shortcut is treated as
a standard Explorer shortcut. If a user changes the content of the
shortcut the header format changes since Explorer creates a completely
different header. Even if the user sets back the R/O attribute the new
header avoids that Cygwin uses the POSIX path in future and the shortcut
is treated as all other Explorer shortcuts. They are treated as a symlink
with only a DOS path pointing to the target.
