--- Comment #69 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Do we have a guarantee that $(RAW_CXX_FOR_TARGET) is always some version of
GCC?
I mean, other compilers might not support -nostdinc++ option at all (older
versions of GCC might not either, but we only support GCC that can do C++11 now
and those all support it).
