Care to share details? Of course there were many changes in the C++ FE, especially for C++0x, and maybe some warnings changed into errors, but nothing I'd describe as a lot. We haven't still written http://gcc.gnu.org/gcc-4.6/porting_to.html so if you have interesting info about changes that affect a lot of packages, details would be certainly welcome. The STL changes not to include <cstddef> internally is certainly one thing that will be added there.
