Hello,

I've an issue with the constructors of fixed_vector. In fixed_vector, MSVC compiler gets confused with these constructors:

    /// \brief Constructor of a fixed_vector with a unique initial value

    /// \param init value to assign to each element of the vector

         BOOST_UBLAS_INLINE

         fixed_vector (const value_type &init):

             vector_container<self_type> (),

             data_ () {

             data_.fill( init );

         }

and

#if defined(BOOST_MSVC)
        // This may or may not work. Maybe use this for all instead only for MSVC
        template <typename... U>
        fixed_vector(U&&... values) :
            vector_container<self_type> (),
            data_{{ std::forward<U>(values)... }} {}
#else
        template <typename... Types>
        fixed_vector(value_type v0, Types... vrest) :
            vector_container<self_type> (),
            data_{ { v0, vrest... } } {}
#endif

because, constructing a vector and providing just an unique initial value, any of these constructors could be called and the compiler reports a warning.

I propose change the second constructor by providing an inilialization_list (instead of a variadiric template), where type of elements of the list can be enforced as well as the length of the list.
