In essence to support big sparse matrices with we have to enable ARMA_64BIT which in turn enforces C++11, because R enforces back compability and long long is not supported unless C++11 is ON.

Here is some info: https://stackoverflow.com/questions/16159174/large-spmat-object-with-rcpparmadillo , seems it is fixed, but if you look at the newest version of RcppArmadillo this is no longer true. To investigate..

Additional constraint comes from random number generation in GNG. This is also not supported in C++ and would require including custom implementation
