There is no magic pixie dust. Some headers are script-generated, even those
scripts are in SVN. Some of the p/q/d/r-sugar functions are from macro
expansions as you will see.

Dear Dirk:
You didn't show the 10 lines. I've looked these over
many times, but I didn't get it until just now. If anybody
else cares, here are the 3 that really matter...
PREFIX/lib64/R/library/Rcpp/include/Rcpp/stats/norm.h
106:RCPP_DPQ_0(norm, Rcpp::stats::dnorm_0, Rcpp::stats::pnorm_0,
Rcpp::stats::qnorm_0 )
107:RCPP_DPQ_1(norm, Rcpp::stats::dnorm_1, Rcpp::stats::pnorm_1,
Rcpp::stats::qnorm_1 )
108:RCPP_DPQ_2(norm, ::Rf_dnorm4, ::Rf_pnorm5, ::Rf_qnorm5 )
To see what is going on, take a look at the combination of
pre-processor macro and C++ template code (AKA magic pixie dust) in
PREFIX/lib64/R/library/Rcpp/include/Rcpp/stats/dpq/dpq.h
Bravo!
