I like those too --- but on _32 bit Windows_ they turn into (or rather: are
implemented as) long long which by the established procedure on CRAN is not
available as it would require -std=c++11 (see yesterday's email).

You can /absolutely/ use int64_t with Rcpp, you simply can't upload a package
using it to CRAN. 

There is nothing I can do about the latter part (and I suggest you take the
issue to r-devel).  

If there is anything I could do better on the Rcpp I am all ears to hear
about it.
