When installing pythran, I had to install g++ 4.7 because std=c++11 doesn't work on g++ 4.6.
Are there any other features missing on g++ 4.6? If it's only that one, a switch to use 'std=c++0x' or 'std=c++11' depending on the g++ version could fix the issue and lower the g++ requirement (for example ubuntu 12.04 LTS is still at g++4.6, so it could prove beneficial)
(And I could implement it in that case)
