The errno descriptions come from the C library where strerror_r() is available and from the built-in table elsewhere, so the output differed between platforms and could not be compared against a reference. Look the errno codes up without printing them and fail when any code is not found. Signed-off-by: Kacper Michajłow <kasper93@gmail.com>
