MSVC by default uses its traditional, but non-conforming, preprocessor. The occasion for the switch is the new `__VA_OPT__` preprocessor macro in C++20, which allows a standard way of handling commas with `__VA_ARGS__`.

It looks as though this strict preprocessor option is not compatible with VS 2019; there's warning inside the compiler's include files that's being escalated to an error. I doubt it's worth developing a workaround. There's a different error in VS 2022. This is from our dependency Changing the description to match these observations. |
