std::tr1::tuple fails to compile in C++11 when defining BOOST_FUSION_DONT_USE_PREPROCESSED_FILES

[ipapadop@…]

Test code:

#include <boost/tr1/tuple.hpp>
#include <boost/tr1/functional.hpp>

int a, b;

std::tr1::tuple<int&, int&> get()
{
  return std::tr1::tuple<int&, int&>(std::tr1::ref(a), std::tr1::ref(b));
}

int main()
{
  std::tr1::tuple<int&, int&> t = get();
  return 0;
} 

It fails to compile in C++11 mode and when BOOST_FUSION_DONT_USE_PREPROCESSED_FILES is defined. Same code compiles fine with Boost 1.48 and 1.49
