So I think it is field-tested enough to give it a try on the 'i386' kernel also. So after your next CVSup, you'll be using these optimization options unless you have different ones specified via "COPTFLAGS" in /etc/make.conf. Please let the freebsd-current@freebsd.org list know if you experience any new problems with your kernel that go away if you set: COPTFLAGS= -O in /etc/make.conf. -- -- David (obrien@FreeBSD.org)
