I see the -O0 option that I added, but afterwards -O2 coming from
somewhere in R.
It seems to come from the CXXFLAGS macro defined in /etc/R/Makeconf.
It's the last to be added to ALL_CXXFLAGS, so you probably have to
overwrite it in ~/.R/Makevars.
Yes. I set both CFLAGS and CXXFLAGS in my Makevars_dbg0 file and let R
use it via R_MAKEVARS_USER.
See R-Admin, 6.3.3, Customizing package compilation, for more.

In my case, the necessary settings needed to be put in CXX11FLAGS,
because rgl defines CXX_STD = CXX11. Thanks to Kevin Ushey and Prof.
Brian Ripley for spotting this.
