Bug ID: 17926
Summary: clang-cl: error compiling VC++ type_traits header
Product: new-bugs
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: new bugs

Classification: Unclassified
I'm using the Windows snapshot from trunk r194000. Using the LLVM-vs2013
toolset, I cannot compile the type_traits header, which is unfortunately
included indirectly throughout the C++ standard library.
The problematic code looks like this:
template<class _Ty,
class... _Args>
struct is_constructible
: _Cat_base<_IS_CONSTRUCTIBLE(_Ty, _Args...)>
{ // determine whether _Ty(_Args...) is constructible
};
with
#define _IS_CONSTRUCTIBLE \
__is_constructible
I get the following compile errors:

is_constructible is not used anywhere in the utility header.
