      Clang does not appear to be able to handle variables using the name
      'noreturn' as it is a new keyword in C++11, but it would normally be
      used as in [[noreturn]] void foo() and not as a variable name. I'm not
      sure if this is a compiler bug or what, but GCC handles it fine at
      the moment.
