I think gcc should simply ignore the __has_cpp_attribute macro, unless it does compile C++ code? if I use other names than __has_cpp_attribute it compiles. I will put some C++ guards around this code, but I still think this is a bug? (And I am compiling with Clang 3.4, but this doesnt support the feature check)
