// 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?
|

// ****************
|
|
// 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.
