What you're all trying to say is this:

Nope, this prevents overriding CXXFLAGS from the environment.
It does not. I do it all the time.
How does the user portably remove/override the -g and -O0 options? It
seems that you are depending on the user's compiler to support a way
to subtract from existing options. You are also expecting that the
user's compiler supports -O0 and doesn't simply exit.
