// 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?
2017-02-15 17:57:22 +01:00
// CATCH_CONFIG_POSIX_SIGNALS : are POSIX signals 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_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.
