But yes, in the case of MSVCs STL, the messages from `std::error_codes` which are used by various LLVM tools produce different strings then using `strerror` (the C function also called by Python) with the same error codes (Specifically, it has different casing).

Or turning the question another way around: We have a couple different bots that build and run the tests, successfully, with MSVC configurations. Are there tests that failed for you in your configuration, that succeed in the setup of the bots? Or are there other tests that aren't run as part of bots that you're fixing? It's all still very vague to me.
