Confirmed. I'm not a specialist in old-times C, but IIRC 
  void f();
simply defined the existence of f(), but not its argument list. For that,
you really needed
  void f(void);

I don't know whether this behavior is changed in later standards, but
at least passing -std=c89 or -std=c99 doesn't change anything for this
warning.
