POSIX symlinks and windows lnk files are two completely different
concepts.  In fact, I believe the latest version of windows has support
for symlinks too.  See

(I don't think we completely match the behaviour of the MS runtime wrt
symlinks, and fixing it would require figuring out how they map the .net
calls to the windows system calls.)

Not at the moment.
