10315	multi_index composite_key find() doesn't work with std::tuple	christephan@…	Joaquín M López Muñoz	"com_key_index.find (boost::make_tuple(...)) works.
While com_key_index.find (std::make_tuple(...)) doesn't compile.

Using gcc4.8.1 with -std=c++11

Sample code:
{{{
#!c++
#include <tuple>
#include <boost/tuple/tuple.hpp>
#include <boost/multi_index_container.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/composite_key.hpp>

using namespace std;
using namespace boost::multi_index;
using namespace boost;

struct Point
{
    string x;
    string y;
    unsigned w;
};

int main()
{
    struct PointX {};
    struct PointYW {};
    multi_index_container<Point,indexed_by<
        ordered_unique <tag<PointX>, member<Point, string, &Point::x>>,
        ordered_unique <tag<PointYW>, composite_key<Point,
            member<Point, string, &Point::y>,
            member<Point, unsigned, &Point::w>
        >>
    >> points;

    points.get<PointX>().emplace (Point{""A"", ""B"", 1});
    points.get<PointYW>().find (std::make_tuple(""B"", 1));
    return 0;
}
}}}

By replacing std::make_tuple --> boost::make_tuple, it does compile.
