      # Unlike GCC and upstream Clang, AppleClang still defaults to `-std=c++98`
      # for some reason. Also, the macOS image on GitHub Actions provides wildly
      # numbered Xcode versions. Thus, rather than varying the compiler version,
      # we set the `-std` flag explicitly in order to vary the language version.
      # (The other two flags are the default provided for CXXFLAGS in Makefile.)
