yes.

You can just prefix your calls with Rf_, so instead of calling dnorm, 
you call Rf_dnorm, etc ...

You can use the RCPP_VERSION macro if you want this to work accross Rcpp 
versions, something like :

#if defined(RCPP_VERSION) && RCPP_VERSION >= Rcpp_Version(0,8,6)
# define my_dnorm Rf_dnorm
#else
# define my_dnorm dnorm
#endif
