Definitely not. The C++11 stuff only applies when the appropriate -std
option is specified, which it had bloody well better not be in this case
because C++11 and C++99 have different libstdc++ ABIs (e.g. the size of
an STL list<> is different).

That's the same as always for C++98/03: only C++11 is different (which
couldn't be set to the right value before owing to lack of a time

At last!

Wait for a failure, then move the errant definition up a bit. (This may
require creating new header files here and there, I suppose.)

It's just code motion, not rewriting. Not hard.
