If someone manages to open a file before rtems_libio_post_driver is run, open() may allocate a file number other than 0 for stdin. This leads to a silent failure of the logic in rtems_libio_post_driver, and confusing behavior because your BSP behaves as if it doesn't have a console. Instead of failing silently, raise an internal error if open() succeeds but gives us an unexpected file number for stdin.
