That looks fine. Can you please give a reproducible example of a
package that compiles correctly on R 3.3.3 but not with R 3.4.0 or R-

Hi!?

Well, my linux distribution has very recent versions?
of everything, so a working C++11 compiler exists:?

$ gcc --version | head -n1?
gcc (GCC) 6.3.1 20170306?

Could wrong ./configure options be at fault here? See:?

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=r-devel#n40?

My sessionInfo():?

$ R-devel --slave -e 'sessionInfo()' | head -n3?
R Under development (unstable) (2017-04-18 r72542)?
Platform: x86_64-pc-linux-gnu (64-bit)?
Running under: Arch Linux?

Thanks, Philipp?
