Where does it say that CRAN Policies are fully specified and written out?

Please just take my word for it based on a few years of dealing with Kurt and
CRAN, and / or experiment yourself with a small (new ?) package of yours.

Because this will not fly I would prefer that the change be rolled back.

Which does not work for me.

Sure, but this seems like is bike-shedding: A local variant already had this
by simply adding -std=c++11 as C++ post-1998 has long long types.  Now you
just renamed the handle, for no real tangible benefit.  I know this is
frustrating, and I don;t mean to be difficult.  But if we fight a fight with
CRAN, let's fight over C++11.  This issue here does not really matter.

We could have an if between c++11 or this define. This way it works for me __and__ as before. Can you handle that.

And personally, I'd prefer a bit more stability in our core headers.  The
previous setting worked for a number of years.

You want stability, I want to make progress. The same fight all over again.
