The following code in the scoped_thread.hpp fails because struct dummy is not public:

#if ! defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)

template <class F, class ...Args, typename = typename disable_if<is_same<typename decay<F>::type, thread>, dummy* >::type> explicit scoped_thread(BOOST_THREAD_FWD_REF(F) f, BOOST_THREAD_FWD_REF(Args)... args) :

t_(boost::forward<F>(f), boost::forward<Args>(args)...) {}

#else

To resolve the problem, it is enough to replace "dummy*" with "void*".

Thanks for the fix.

According to my test runs with vc12, the fix is fine!
