Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I'm here with Richard, by using -std=c++11 for stage1 we get (at least to some extent) verification that we aren't relying on GNU extensions and can use other host compilers. Of course, further stages should just use whatever g++ defaults to.
