As we recently established, G_G*_FORMAT macros are for glib functions *only*. It's not guaranteed that they will work for C runtime printf() or scanf() variants, and indeed - in this case they do not (GCC thinks that MSVCRT sscanf() requires %I64 prefix for 64-bit values; whether that is true or not is irrelevant at this point - we need to make the werror go away).
