I introduced something similar to this:

template<typename _Key> using my_set = unordered_set<_Key>;

in my program. It compiles fine on my computer (gcc 4.7.2) but on the Cluster I get the error:

error: expected unqualified-id before ‘using’

I believe I read somewhere the hard- and software specifications of the cluster, but I can't find them. So, is there a bug in my code or is the gcc on the cluseter < 4.7?
