This brings up a BIG issue. Might we need to revert some of the gcc 4.7.0 patches? The it -> it2 stuff shouldn't matter
That was required due to an intentional change in GCC 4.7 for better conformance to the C++ Standard, so it's not likely to be reverted in point releases (or at all). (If it *did* somehow get reverted, *that* would be a bug in GCC.)
