respect CFLAGS: should I override optimizations?

I'm updating biology/migrate, the upstream includes


and configure says:

case "$GCC" in
	yes) CFLAGS="-O3 -Wall -ffast-math -funroll-loops -fomit-frame-pointer -fexpensive-optimizations -D$CPUTYPE" ;;
If I was to take Porter's Hang^Hdbook literally, I would change the
set (=) to append (+=) and be done with it, but is that really what
I'm expected to do? Or should I filter out the -O3 on the assumption
that optimization levels are make.conf's business?

If you cc me or remove the list(s) completely I'll most likely ignore
your message.    see
