// Detect a number of compiler features - mostly C++11/14 conformance - by compiler
// The following features are defined:
//
// CLARA_CONFIG_CPP11_NULLPTR : is nullptr supported?
// CLARA_CONFIG_CPP11_NOEXCEPT : is noexcept supported?
// CLARA_CONFIG_CPP11_GENERATED_METHODS : The delete and default keywords for compiler generated methods
// CLARA_CONFIG_CPP11_OVERRIDE : is override supported?
// CLARA_CONFIG_CPP11_UNIQUE_PTR : is unique_ptr supported (otherwise use auto_ptr)
// CLARA_CONFIG_CPP11_OR_GREATER : Is C++11 supported?
// CLARA_CONFIG_VARIADIC_MACROS : are variadic macros supported?
// In general each macro has a _NO_<feature name> form
// (e.g. CLARA_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 CLARA_CONFIG_NO_CPP11
