Pointless, as I said before.

If you switch your compiler (VC++) to a mode that is not compliant to
the C++ standard and the compiler accepts some code then that doesn't
indicate whether the code is correct.

The header, as has been pointed out clearly, lacks include guards. So
gcc is *correcly* complaining if that header gets included multiple
times. At that point, there's no point in discussing the version number
of a compiler that emits a seemingly correct error message. Any
suggestion to upgrade the compiler to fix that error a misleading.

You may want to upgrade your compiler anyway. The version number seems
to indicate one of that homebrew compilers from Red Hat, which used to
come with a lot of (unrelated) problems in the past.
