    Fix a compile warning on ARM.
    
    Aapo Rantalainen points out that comparing 'char c' against zero gives
    rise to gcc's "comparison is always false" warning, which escalates to
    an error under -Werror.
    
    This is one of those situations where the warning is doing more harm
    than good, but here's a rephrasing which casts to unsigned so that
    both negative numbers and positive out-of-range ones can be caught by
    the same comparison.
