I'm just finishing testing and will push this. I had to add <memory> to the new codecvt_unicode.h header, and fixed some formatting in codecvt (we don't put a space before function parameter lists in the libstdc++ code, unlike in the code for the GCC compiler itself). I've also made the changelog entry a bit more descriptive. Thanks again for the bug report and for fixing it!
