[Rd] R compilation on old(ish) CentOS

[Henrik Bengtsson]

Ben, it's most like what Peter says.  I can confirm it works; I just
installed https://cran.r-project.org/src/base-prerelease/R-latest.tar.gz
on an up-to-date CentOS 7.9.2009 system using the vanilla gcc (GCC)
4.8.5 that comes with that version and R compiles just fine and it
passes 'make check' too.

Since R is trying to move toward C++14 support by default, I agree
with Iñaki, you might wanr to build and run R with a newer version of
gcc.  gcc 4.8.5 will only give you C++11 support.  RedHat's Software
Collections (SCL) devtoolset:s is the easiest way to do this. I've
done this too and can confirm that gcc 7.3.1 that comes with SCL
devtoolset/7 is sufficient to get C++14 support.  I'm sharing my
installation with lots of users, so I'm make it all transparent to the
end-user with environment modules, i.e. 'module load r/4.1.0' is all
the user needs to know.
