  Portability problems not fixed by Gnulib:
  @itemize
  @item
  When @code{readlink} is called on a directory: In the case of NFS mounted
  directories, Cygwin sets @code{errno} to @code{ENOENT} or @code{EIO} instead of
  @code{EINVAL}.  To avoid this problem, check for a directory before calling
  @code{readlink}.
  @item
  When @code{readlink} is called on a file that is not a symbolic link:
  Irix may set @code{errno} to @code{ENXIO} instead of @code{EINVAL}.  Cygwin
  may set errno to @code{EACCES} instead of @code{EINVAL}.
  @end itemize
