The repo code

It seems that _Bool is a predefined type in Clang, yet the following (reduced)
code fails to compile:

#ifndef __clang__
typedef bool _Bool;
#endif
template<class _Iter>  struct iterator_traits  {
};
template<> struct iterator_traits<_Bool>  {
};

Output from "clang -cc1 traits_red1.cpp":

traits_red1.cpp:6:35: error: expected expression
template<> struct iterator_traits<_Bool>  {
                                  ^
traits_red1.cpp:6:1: error: extraneous 'template<>' in declaration of struct
(null)
template<> struct iterator_traits<_Bool>  {
^
traits_red1.cpp:6:12: error: anonymous unions at namespace or global scope must
be declared 'static'
template<> struct iterator_traits<_Bool>  {
           ^
traits_red1.cpp:6:12: error: anonymous structs and classes must be class
members
4 errors generated.
