Thanks for your interest in Rcpp!

I do not plan to have these exported.  Rcpp:::CxxFlags() and Rcpp:::LdFlags()
do exactly what they are supposed to do.

Further, exporting the short names may only clash due to namespace
collissions.  At least RInside also used RInside:::CxxFlags() and

So I'd need strong arguments for exporting this, beyond the main reason
Romain already gave:  They are not meant for the loaded package (which only
provides some documentation).


Three out of two people have difficulties with fractions.
