I managed to fix some of the issues of gcc 4.6, however I still think 
there are many issues with this compiler.

For instance, the following code

     template<typename T>                                        \
     binary_expr<ExprType,T,                                     \
         op::name<ValType,typename RhsT<T>::type> >              \
     operator oper( T&& rhs )                                    \
     {                                                           \
         return binary_expr<ExprType,T,                          \
          op::name<ValType,typename RhsT<T>::type> >             \
             ( std::forward<ExprType>(                           \
                 *static_cast<ExprType*>(this) ),                \
               std::forward<T>(rhs) );                           \
     }                                                           \

seem to yield a different type "T" between the return type at the 
function declaration and the return statement in the function body.

(the difference is in the "Rhs", the error is
=======
test-organization-ts/test_case_template-test.cpp:38:5: error: 
‘boost::test_tools::assertion::binary_expr<Lhs, Rhs, OP>::evaluate(bool) 
const [with LExpr = boost::test_tools::assertion::value_expr<int>, Rhs = 
int&, OP = boost::test_tools::assertion::op::EQ<int, int, void>]’ is not 
a member of 
‘boost::test_tools::assertion::binary_expr<boost::test_tools::assertion::value_expr<int>, 
int, boost::test_tools::assertion::op::EQ<int, int, void> >’
=======
)

I am also experiencing errors that are outside of boost.test (see below).
If anyone has experience with this compiler (and is willing to help), 
please do.

Best,
Raffi
