RcppEigen 0.3.3.5.0

Another minor release 0.3.3.5.0 of RcppEigen arrived on CRAN today (and just went to Debian too) bringing support for Eigen 3.3.5 to R.

As we now carry our small set of patches to Eigen as diff in our repo, it was fairly straightforward to bring these few changes to the new upstream version. I added one trivial fix of changing a return value to void as this is also already in the upstream repo. Other than that, we were fortunate to get two nice and focussed PRs since the last release. Ralf allowed us to use larger index values by using R_xlen_t, and Michael corrected use of RcppArmadillo in a benchmarking example script.

Next, it bears repeating what we said in February when we release 0.3.3.4.0:

One additional and recent change was the accomodation of a recent CRAN Policy change to not allow gcc or clang to mess with diagnostic messages. A word of caution: this may make your compilation of packages uses RcppEigen very noisy so consider adding -Wno-ignored-attributes to the compiler flags added in your ~/.R/Makevars.

It’s still super-noise, but hey, CRAN made us do it …

The complete NEWS file entry follows.
