So is this ill-formed:

-----------------------------
class N;
struct S
{
    void f(N* );
    class N;
};
-----------------------------

or, given the following bullet, "If reordering member declarations in a class
yields an alternate valid program under (1) and (2), the program is illformed,
no diagnostic is required.", is this ill-formed:

-----------------------------
class N;
struct S
{
    class N;
    void f(N* );
};
-----------------------------

?
