enable_shared_from_this not working on xcode 5

#include <iostream>
#include <memory>

template<typename T>
class Test: public std::enable_shared_from_this< Test<T> >
{

public:

    std::shared_ptr< Test<T> > getMe()
    {
        return shared_from_this();
    };

};

int main(int argc, const char * argv[])
{
    Test<int>   aTest;

    return 0;
}

When i try to compile this on Xcode 5 i get 

Use of undeclared identifier 'shared_from_this'

I tested it and its working on Visual Studio 2010.

    return this->shared_from_this();
           ^^^^^^

VC++ 2010 does not implement the lookup rules for templated base classes exactly correctly. The clang behavior is correct. The above fix will make it work on both your platforms.
