Symbolic links

What happens if you try to create a symlink to a zero-length target, as in ln -s "" foo?
Linux: ENOENT.
Mac OS X 10.4: EINVAL.
FreeBSD: works, and any attempt to resolve the symlink returns ENOENT.
Solaris: works, and the resulting symlink behaves the same as ln -s . foo

/tmp/foo
$ cd ""
$ set -P
$ cd ""
bash: cd: : No such file or directory
But really this is caused by the same disagreement. Bash is behaving as I would expect and assuming chdir("") is a noop. But Linux apparently gives an error.
