        PR fortran/50016
        * io/file_pos.c (st_flush): Call _commit on MinGW(-w64).
        * io/intrinsics.c (flush_i4, flush_i8): Ditto.
        * io/unix.c (flush_all_units_1, flush_all_units): Ditto.
        (buf_flush): Remove _commit call.
        * io/inquire.c (inquire_via_unit): Flush internal buffer
        and call file_length instead of invoking stat via file_size.
