Yeah, except I'm not trying to test <stop_token>. I'm just trying to include <condition_variable>, which includes <stop_token> and hard-errors. In fact, what I'm _really_ trying to do is include <regex>, which includes <memory_resource>, which includes <shared_mutex>, which includes <condition_variable>. All roads, it seems, lead to <stop_token>.
