It might be fine, actually. I have a package with long long on CRAN, and
yes, they asked me to "fix it", but like for you, it is in upstream code,
so I am not really comfortable removing it, and CRAN seems to be OK with it
now.

Other packages seem to have it, too:

I doubt that these all require C++11.

Also, all compilers they use have long long, so what is the point, really?
