Just note that make check-g++ defaults to testing c++98, c++20 and c++26
(except for tests which require some particular C++ version, in that
case it can slightly differ). So, the c++11 FAILs don't appear unless
one tests all.
There is also make check-c++-all (but that for some reason misses c++26;
will post a patch for that).
