Please define 'cran compatible'.  

It has been on CRAN since Jan 2013, and has now had seven releases. Good enough?

If you look at the history of the BH package (very public on GitHub and
previously on R-Forge) you will see that we do respond to requests for
additions -- provided those 'fit' into the framework and are template-only.

We do currently have .../BH/include/boost/rational.hpp and glancing at the
page you link to above that is all there is for it. Grep sees no further
#include use for anything named ...rational... --- so why don't you just try BH?
