     // And that it mangles the same in C++03 through C++17
+#ifdef _MSC_VER
+    // MSVC uses a different C++ ABI with a different name mangling scheme.

This isn’t so much about the compiler itself, but the platform ABI. With clang-cl, you don’t get that macro defined, but only TEST_COMPILER_CLANG, while it obeys the Microsoft C++ ABI. I don’t see any existing defines there for that aspect.
