For a long period of time, we (in the GCC/g++ front-end land) did not
make much distinction between C++98 and C++03 because the latter
is just a bug fix of the former.  I am not sure we are using any
construct for which the distinction would matter in practice or
whether there is any real C++ compiler used to bootstrap GCC for
which the fine distinctions matter.
