 // Detect a number of compiler features - by compiler
 // The following features are defined:
 //
 // CATCH_CONFIG_COUNTER : is the __COUNTER__ macro supported?
 // CATCH_CONFIG_WINDOWS_SEH : is Windows SEH supported?
 // CATCH_CONFIG_POSIX_SIGNALS : are POSIX signals supported?
 // CATCH_CONFIG_DISABLE_EXCEPTIONS : Are exceptions enabled?
 // ****************
 // 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_NO_POSIX_SIGNALS) 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.
