Seems some of the std::any conformance changes broke for the GCC included in the Xcode 4.6.2.

The same error is seen with '--std=c++-98':

But regardless, I'm not sure how well gcc 4.2 will be supported in the future. It's a pretty old compiler.

Regardless of whether GCC 4.2 should be supported or not, in C++03 T& is invalid if T is already a reference. It's a good thing that GCC 4.2 could catch this issue.
