    Work around a language defect
    
    It is ridiculous that <iomanip> prescribes an 'int' argument for
      setprecision(int n);
    but <ios> prescribes a 'std::streamsize' argument for
      ios_base::precision(streamsize prec);
    and especially that the LWG chose not to remove the inconsistency:
      http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-closed.html#1148
    which was found in this case by compiling for 64-bit msw.
