I suspect this is a hopeless request, but I'm going to ask anyway -- the toolchain which ships with QtSDK for harmattan is rather old, it doesn't support C++11's lambdas, among other things.

Is there a compiler one could use which has support for more C++11 features (like the lambdas or nullptr) and at the same time doesn't require an extensive update to the libstdc++ installed on device? Basically, either a recent clang or GCC 4.7+.
