The problem is that CL:DIRECTORY is specified to apply TRUENAME which is
specified to resolve symbolic links.  (See section 20.1.3 Truenames).

There is no conforming way to obtain the pathname of a symbolic link in
CL.  You have to use an extension, either an implementation specific
keyword argument to DIRECTORY, or an implementation specific function.

On POSIX systems, I'd advise to use the POSIX API thru CFFI to deal with
the POSIX file systems.
