[Rcpp-devel] g++ flags

[Gabor Grothendieck]

I am now getting latex errors when I try to install Rcpp from github
(see below) but it does now work (without the vignettes) if I use:
   github_install("RcppCore/Rcpp", build_vignettes = FALSE)
so at least I can proceed without explicitly setting any environment
variables now.
Thanks.
