It is, but that is not enough.  The same problem occurs with

  (let ((toto 1))
    (defun foo ()))

  (defun bar ()
    (foo))

In this case, the byte-compiler will also fail to see that `foo' is being
defined and will hence signal "Warning: the function `foo' is not known to
be defined".

eval-and-compile is ugly.
