Hello,
following minimal code compiles fine with 1.52 and
BOOST_THREAD_VERSION defined to 3 but gives compilation error with
1.53 release (Visual Studio 2008 SP1, Win 7):
#include
#include
class Dummy
{
public:
Dummy& operator=(BOOST_RV_REF(Dummy) other);
Dummy& operator=(BOOST_COPY_ASSIGN_REF(Dummy) other);
BOOST_COPYABLE_AND_MOVABLE(Dummy);
};
Dummy createDummy();
int main()
{
boost::future<Dummy> df = boost::async(&createDummy);
}

Btw: why BOOST_THREAD_VERSION is still 2 when documentation says it is
4.0.0 as of boost 1.53?
