    Prevent localizing the decimal point in gcc<5.
    
    Apparently gcc V4.8 provides a defective implementation of
    std::locale which first doesn't support std::numpunct and second
    throws the wrong exception type.
    
    Unfortunately boost::locale isn't a solution because it uses the
    gcc facets.
    
    So for now, we don't compile that bit if gcc is too old.
