Everything is intended to mean "C++XX and up" now.  But c++98 isn't 
defined, since it would be meaningless.  And so it isn't used in tests 
either.  So for c++98 only you can use c++98_only or { ! c++11 }.

On a highly parallel system, it doesn't affect testing time because one 
of the chunks of libstdc++ tests still takes longer than any of the 
chunks of g++ tests.
