Hi,
The following file fails to compile under clang 2.9 c++0x
#include <boost/static_assert.hpp> #include <boost/type_traits/is_enum.hpp>
enum E {E_a,E_b,E_c}; BOOST_STATIC_ASSERT((boost::is_enum<E>::value)); enum class EC {a,b,c}; BOOST_STATIC_ASSERT((boost::is_enum<EC>::value));

Am I missing something evident? Is this a known bug of is_enum?
BTW, I have tried to use directly the type_traits standard file and my build configuration is unable to find it.
enum_class/is_enum_pass.cpp:9:10: fatal error: 'type_traits' file not found #include <type_traits>
Normally this is: #include <boost/type_traits.hpp>
