As was said, then the users of such compilers won't get perfect Qt5 code
generated. That being said, I think its reasonable to expect the Qt5 devs
to also run gcc 4.7 or maybe even 4.6. Hence features used by Qt5 will in
turn probably be available with those versions already. I don't expect the
Qt developers to be using gcc from a development branch.

So I think right now its safe to assume with gcc 4.7 you should get all
those C++ 11 features
that Qt5 uses and hence optimal Qt5 code generated.
