I'm using MSVC14 CTP2 and clang-cl r212716.

I get the following 4 compile errors in <type_traits>:

error : use of undeclared identifier '__vectorcall'
in macro
#define _EMIT_VECTORCALL(FUNC, CONST_OPT, CV_OPT) \
    FUNC(__vectorcall, CONST_OPT, CV_OPT)

error : '_Types' does not refer to a value
in macro
#define _IS_FUNPTR(CALL_OPT, X1) \
template<class _Ret, \
    class... _Types> \
    struct _Is_funptr<_Ret (CALL_OPT *)(_Types...)> \
        : true_type \
    {    /* base class for function pointer predicates */ \
    };

error : '_Types' does not refer to a value
in macro
#define _IS_MEMFUNPTR(CALL_OPT, X1, CV_OPT) \
template<class _Ret, \
    class _Arg0, \
    class... _Types> \
    struct _Is_memfunptr<_Ret (CALL_OPT _Arg0::*)(_Types...) CV_OPT> \
        : true_type \
    {    /* base class for member function pointer predicates */ \
    };

error : '_Mfargs' does not refer to a value
in macro
#define _RESULT_OF_PMF(CALL_OPT, CONST_OPT, CV_OPT) \
template<class _Ret, \
    class _Ty, \
    class... _Mfargs, \
    class _Obj, \
    class... _Args> \
    struct _Result_of<_Ret (CALL_OPT _Ty::* CONST_OPT)(_Mfargs...) CV_OPT, \
        _Obj, _Args...> \
    {    /* template to determine result of call operation */ \
        /* on pointer to member function */ \
    typedef _Ret type; \
    };

The marcos are used in
_NON_MEMBER_CALL(_IS_FUNPTR, )
_MEMBER_CALL_CV(_IS_MEMFUNPTR, )
_MEMBER_CALL_CONST_CV(_RESULT_OF_PMF)
