  // The following features are defined:
  //
  // CATCH_CONFIG_CPP11_NULLPTR : is nullptr supported?
  // CATCH_CONFIG_CPP11_NOEXCEPT : is noexcept supported?
  // CATCH_CONFIG_CPP11_GENERATED_METHODS : The delete and default keywords for compiler generated methods
  // CATCH_CONFIG_CPP11_IS_ENUM : std::is_enum is supported?
  // CATCH_CONFIG_CPP11_TUPLE : std::tuple is supported
  // CATCH_CONFIG_CPP11_LONG_LONG : is long long supported?
  // CATCH_CONFIG_CPP11_OVERRIDE : is override supported?
  // CATCH_CONFIG_CPP11_UNIQUE_PTR : is unique_ptr supported (otherwise use auto_ptr)
  
  // CATCH_CONFIG_CPP11_OR_GREATER : Is C++11 supported?
  
  // CATCH_CONFIG_VARIADIC_MACROS : are variadic macros supported?
  // CATCH_CONFIG_COUNTER : is the __COUNTER__ macro supported?
  // ****************
  // Note to maintainers: if new toggles are added please document them
  // in configuration.md, too
  // ****************
  
  // In general each macro has a _NO_<feature name> form
  // (e.g. CATCH_CONFIG_CPP11_NO_NULLPTR) which disables the feature.
  // Many features, at point of detection, define an _INTERNAL_ macro, so they
  // can be combined, en-mass, with the _NO_ forms later.
  
  // All the C++11 features can be disabled with CATCH_CONFIG_NO_CPP11
