Please. I’d like a newer gcc as part of Rtools too. My reason for it is that it would bring actual C++11, rather than unfinished C++0x as gcc 4.6.3 currently ships. That would allow more adoption of the newer C++ standard for packages [*]. Furthermore, a current version of gcc will also give a good support for C++14, the current C++ standard. I said it in the past, I don’t have the skills to make this happen myself but I would consider funding someone’s time (within reason) and offer mine for testing it. Romain *: currently Rcpp11, the best way to connect R and C++11, has to compromise on what C++11 means so that it works on windows. This is bad. The compromise is minimal, but still. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
