commit 842ad56879c8abe4ff8bc6ccc5097d2755e52527

    Return different exit codes when gai_result is > -100
    
    Make the result checkable from the command line even without verbose
    mode. Keep original exit status 2 for name not found error. But report
    other errors by exit status greater than 10.
    
    For too high values make it return 2 as before.
