Is there a reason this is preferred over using override/final in
the sources directly, and then define them away as empty
on pre-C++11?

I mean:

#if __cplusplus < 201103
# define override
# define final
#endif

then use override/final throughout instead of OVERRIDE/FINAL.

If building gcc as a C++11 program is supported, then it
won't be possible to use these names as symbols for
anything else anyway?

Thanks,
