Compile error with SunStudio: unique_future move

[anonymous]

// B.cpp
#include <boost/thread.hpp>

static int function() {
  return 42;
}

int main(int argc, const char *argv[]) {
  boost::packaged_task<int> pt(function);
  boost::unique_future<int> future = pt.get_future();
  return 0;
}

When trying to compile this I get this error:

"B.cpp", line 10: Error: boost::unique_future<int>::unique_future(boost::unique_future<int>&) is not accessible from main(int, const char). 1 Error(s) detected.

There is an action point to use Boost.Move. Could we consider this as a duplicate of #6194 Adapt to Boost.Move.

The current implementation doesn't works on SunStudio as it is preferring the overload to the private constructor instead of the conversion.

I have added a move() member function that should help to force the conversion in trunk. You can add the following

        boost::detail::thread_move_t<unique_future> move()
        {
            return boost::detail::thread_move_t<unique_future>(*this);
        }

Could you try this

  boost::unique_future<int> future = pt.get_future().move();

Let me now if this work for you. I will add some documentation explaining the limitation on SunStudio.
