State-Changed-Why:
    In fact, as prescribed by 27.8.1.11, ios_base::out *is*
    present but together with ios_base::in, that is
    ios_base::in | ios_base::out is the default open mode of an
    fstream. However, the meaning of such an open mode is the
    same of the "r+" mode in C (27.8.1.3, Table 92), that is
    *file must exist*.
    To the contrary, the open mode of ofstream is ios_base::out,
    which creates if necessary (27.8.1.8).
    
    Thanks for your report, Paolo.
