These latter two are weird. Normally, g++ knows where to finds its own
headers, so you shouldn't need these. In fact they might be wrong because
if you're using 3.4 and redirect it to 3.3 headers anything might happen.

What I also wonder here is why _GLIBCXX_CONCEPT_CHECKS isn't defined, I
thought it was on by default. I could be wrong however.
