Hello.

sys/conf/Makefile.kern.inc 1.13.4.8 (-rnetbsd-1-6) annoys me
because whatever COPTS I define, "-O2" is appended to it.

However, simply reverting to the previous brings back another problem
again - see the log below. What is a good solution?

Pull up revision 1.23 (requested by sjg in ticket #877):
  Replace COPTS?= with COPTS+=, so that setting COPTS in
  /etc/mk.conf (common on sparc systems) does not cause the
  -O2 in DEFCOPTS to be lost, resulting an an unloadable
  kernel on sparc.
