From 0e33f1110fa2abdbdf1c719b81e138009119ecaa Mon Sep 17 00:00:00 2001 From: Philip Withnall Date: Fri, 1 Apr 2022 13:44:45 +0100 Subject: [PATCH] tests: Add C++ tests for typechecking with atomic compare and exchanges The tests have to be conditional on C++11 being enabled, as the default C++ standard on macOS is (for some reason), C++97 (`__cplusplus` is defined as `199711L`).
