Sorry, I don't think I understand what you're trying to say in these two
pragraphs. What does "defined COPTFLAGS in /etc/src.conf accordingly"
Likewise, what does " CFLAGS set, either in make.conf, or src.conf or
mutual exclusive" mean?
It may be best to give concrete examples of make.conf/src.conf settings
pairs, and the observed behavior.

COPTFLAGS (str) Controls the compiler settings when building the ker-
nel. Optimization levels above [-O (-O2, ...)] are not
guaranteed to work.
Note the last sentence.
