Nonetheless, on the two systems that I tested (FreeBSD and Mac OS X), __cplusplus is defined as follows (respectively): <built-in>:377:21: note: expanded from here #define __cplusplus 201402L and <built-in>:393:21: note: expanded from macro '__cplusplus' #define __cplusplus 199711L There might be a way to accurately check whether the “test()” member function is defined for "std::atomic_flag”, but checking "__cplusplus >= 202002L” is definitely not the right way to do so.
