a much nicer way is compiling the attached program, installing
gcc/g++/cc/c++/make symlinks in a place where it is found first (i have
/usr/local/bin first in PATH, so that's a good place), exporting
WRAPCCFLAGS (i have WRAPCCFLAGS=cache,ice=40, because i want caching and
have a fairly big icecream farm at hand), and everything just works.
always. unless you run into a buildsystem which does not support
parallelization or does not like ccache or icecream, then you may need
to adjust the flags to disable it.
