Sure -- just remove the offense warning from ~/.R/Makevars.

Here is what I use:

CFLAGS +=              -O3 -Wall -pipe -pedantic -std=gnu99 
CXXFLAGS +=           -O3 -Wall -pipe -Wno-unused -pedantic 
FFLAGS += -O3 -g0 -Wall -pipe
FCFLAGS += -O3 -g0 -Wall -pipe
VER=
CCACHE=ccache
CC=$(CCACHE) gcc$(VER)
CXX=$(CCACHE) g++$(VER)
SHLIB_CXXLD=g++$(VER)
FC=ccache gfortran$(VER)
F77=$(CCACHE) gfortran$(VER)
#CXX1X=ccache g++$(VER)
#CXX1XFLAGS=-O3 -Wall -pipe -Wno-unused -pedantic 
#CXX1XFLAGS=-O3 -Wall -pipe -Wno-unused
#CXX1XSTD = -std=c++0x

(The real file is a little longer, I sometimes comment things in and out.)

(My $RHOME/etc/Makeconf also has more settings based on the Debian/Ubuntu config.)
