wrong. A workaround was applied on 2012-06-23, in 4.7.1-2ubuntu1. The complete reversal of the offending patch (with the same effect) is on the gcc-4.7 branch and will get into quantal with the next merge. Please note that just using gcc-4.6 will help for this particular issue, but it's not about a 4.6/4.7 issue, but about mixing c++98 and c++11 code. The c++03/c++11 support in GCC has always been marked as experimental, and still is, so you may run into another incompatibility. There is a discussion going on what can be done about the compatibility, see http://gcc.gnu.org/ml/gcc/2012-07/msg00031.html, but for now just be aware that this compatibility is not granted. >> I've been mentioning that for a few weeks but I've seen no recent update, >> is anyone working on it?

But it's no guarantee that the there are other incompatibilities. The std::list issue is now reverted in 4.7 as well.
