Dan,
Cygwin symlinks are a bit more than read-only shortcut (.lnk) files.
They have a special format, and they also have something in their
"Comment" field (that you can check via shortcut properties). In short,
you cannot easily create a Cygwin symlink from outside Cygwin. For exact
details, see the source of the symlink() function in
winsup/cygwin/path.cc.
