Hi,
I grabbed an mpl cross product implementation (product_view) of this
 mailing list. It works fine in MSVC but fails in gcc:
It doesn't work because you're relying on
implementation details.  Use boost::mpl::at_c::type
instead of XXX::item0.

BOOST_AUTO_TEST_CASE_TEMPLATE(MyTest, DecimalIntegralT,
EachDecimalWithEachIntegralT)

    {
        typename DecimalIntegralT::item1 r(1234567);   // Fails on
gcc: no type named ‘item0’ in ‘struct boost::mpl::v_item, 0>, 0>
        typename DecimalIntegralT::item0 d(r);
BOOST_CHECK_EQUAL(static_cast<long long>(d), r);
    }
}
