Saying
        typedef enum foo {a, b, c};

is about like saying
        typedef int;
or      typedef struct foo {int a;int b;int c};

In none of these three cases has a new type name been introduced.
Presumably what was meant was

        typedef enum {
                initial_ok, middle_ok, final_ok
                } s_state_ok;

The first line where s_state_ok is typedef'ed to be an (int) is not
necessary (or legal, or wanted) once it has correctly been coined as an
enum type.
