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]

I have made the test for gcc4.6 for BOOST_NO_CONSTEXPR and BOOT_NO_NULLPTR that seems to work.

I have attached the patch in case you want to update the gcc.hpp file for gcc-4.6. 
I don't know if someone is interested in macros for these features.
* Universal character name literals N2170 GCC 4.5 
* No Standard Layout Types N2342 GCC 4.5
* Local and unnamed types as template arguments N2657 GCC 4.5

Thanks for all,
Vicente
