--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-01-20 09:37:25 UTC --- Right now I think cc1/cc1plus/etc. would be happy even with an empty libstdc++.a (they are compiled with -fno-exceptions -fno-rtti, so shouldn't need even libsupc++) and go1 I think uses just the c++98 stuff and libsupc++.
