Bug ID: 17146
Summary: LLVM Toolset fails to correctly parse bitset header
Product: new-bugs
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P

The VC11 bitset header fails to parse with Clang. Here is the offending code:
#define _BITSET_SIZE_TYPE \
typename basic_string<_Elem, _Tr, _Alloc>::size_type
template<class _Elem,
class _Tr,
class _Alloc>
explicit bitset(const basic_string<_Elem, _Tr, _Alloc>& _Str, // line
166
_BITSET_SIZE_TYPE _Pos = 0,
_BITSET_SIZE_TYPE _Count = basic_string<_Elem, _Tr, _Alloc>::npos,
_Elem _E0 = (_Elem)'0',
_Elem _E1 = (_Elem)'1')
{ // construct from [_Pos, _Pos + _Count) elements in string
_Construct(_Str, _Pos, _Count, _E0, _E1);
}
VC accepts this code without complaint, and I don't see any errors.
The given error is
1> G:\Program Files (x86)\Microsoft Visual Studio
11.0\VC\include\bitset:168:62: error: expected ')'
1> _BITSET_SIZE_TYPE _Count = basic_string<_Elem, _Tr,
_Alloc>::npos,
