it's related to the change to IPAddress.h, that was changed because of gcc 4.7. We also will have to upate W5100*. i posted a comment at [1] agreeing with a poster that has a similar problem. It call comes down to the fact that IPAddress.h and .cpp: "Poor code quality here. The 4-octet class member is forcibly type-punned to an incompatible type in several places. This hack forces gcc to disable an entire class of optimisations. The new compiler automatically enables strict-aliasing when size optimisations are selected so we get told about this. The fix is to declare the 4-octet member as a union so it can be used in a type-safe manner."
