Thanks. This works.

John, the differences between 4.5 an 4.4 seems to be all already in place.

    BOOST_NO_EXPLICIT_CONVERSION_OPERATORS   [no value]
    BOOST_NO_LAMBDAS                         [no value]
    BOOST_NO_NUMERIC_LIMITS_LOWEST           [no value]
    BOOST_NO_RAW_LITERALS                    [no value]
    BOOST_NO_SCOPED_ENUMS                    [no value]
    BOOST_NO_UNICODE_LITERALS                [no value]

Thanks for checking this, John.
