> But this one [0] seems to indicate you might need at least 16.5 for this. Ah, that says Starting in Visual Studio 2019 version 16.5, preprocessor support for the C++20 standard is feature-complete. These changes are available by using the /Zc:preprocessor compiler switch. The reference to C++20 is a bit confusing in this context; does C++ really have a different preprocessor? But anyway, the support matrix seems like a convincing argument that we don't have to support 16.3. If Andrew is willing to update drongo, I'm content to leave it at that. regards, tom lane
