That macro would be a good idea anyway, since otherwise detecting
#if defined(__GLIBCPP__) || defined (__GLIBCXX__)
There are already places that don't detect GCC 3.4's libstdc++ because
they haven't been updated to check for __GLIBCXX__ as well as
__GLIBCPP__. Your suggested macro would make it easier to get right.
