In fact, to *build* libstdc++ you definitely need G++.
An installed libstdc++ *might* be usable with other compilers such as ICC and
Clang that offer a sufficient level of GCC compatibility, but to install it in
the first place you need to use GCC. If Apple or anyone else wants it to work
otherwise they need to do the work, as GCC maintainers have no reason to do
support building parts of GCC without GCC!
