Even in C99 varargs functions can be called without arguments.
The question here is more subtle.  In fact it is possible even
in C99 and C11 to do what he wants, but it isn't easy, and it
is far from obvious how to go about it.  Still, if the question
is "can this be done?", the answer is Yes even now.
