--- Comment #5 from David Holm <dholmster at gmail dot com> --- Thank you for the detailed replies. I will create an issue towards abseil and see if I can convince them to use __has_include instead. -Wno-error=deprecated does not seem to work, however -Wno-error=cpp does and we can use that as a workaround since the scope is limited to a handful of source files.
