Now that you mention it, it's indeed not as clear as I thought. 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).
