[R-sig-Debian] Ubuntu 16.10 Yakkety Yak uses GCC 6 but -std=c++98 is missing

[Kirill Müller]

After upgrading to Ubuntu 16.10, which brings GCC 6, I've noticed that 
packages are compiled in C++14 mode by default. Here's what a g++ 
command for compiling one of Rcpp's modules look like on my system:

g++ -I/usr/share/R/include -DNDEBUG -I../inst/include/     -fpic  -g -O2 
-fstack-protector-strong -Wformat -Werror=format-security -Wdate-time 
-D_FORTIFY_SOURCE=2 -g  -c barrier.cpp -o barrier.o

According to GCC news [1], the default is now C++14 if no -std is given. 
R-admin suggests adapting the configuration for GCC 6 [2].

I'm using r-base-core in version 3.3.2-1xenial0 from the Ubuntu repo 
[3]. Please advise.


Best regards

Kirill
