port problems after update to DragonFly_Stable

   buildkernel does use COPTFLAGS from /etc/make.conf when building kernel

Thanks for the answer, but I'm still a little confused: doesn't it apply 
to kernel modules ?

I put the following values in my make.conf:

CFLAGS=-Os -pipe
COPTFLAGS=-O -pipe
It seems to me that I get some files compiled with -O (kernel) and 
others with -Os (modules) (output taken from the same buildkernel):

cc -c -O -pipe -march=athlon -Wall -Wredundant-decls -Wnested-externs 
-Wstrict-prototypes  -Wmissing-prototypes -Wpointer-arith -Winline 
-Wcast-qual  -ansi -g -nostdinc -I. -I/usr/src/sys 
-I/usr/src/sys/../include -I/usr/src/sys/contrib/dev/acpica 
-I/usr/src/sys/contrib/ipfilter  -D_KERNEL -include opt_global.h  
-mpreferred-stack-boundary=2 -fno-common -ffreestanding  
/usr/src/sys/dev/disk/advansys/adv_isa.c

===> bus/firewire
cc -Os -pipe -march=athlon  -D_KERNEL -Wall -Wredundant-decls 
-Wnested-externs -Wstrict-prototypes  -Wmissing-prototypes 
-Wpointer-arith -Winline -Wcast-qual  -ansi -DKLD_MODULE -nostdinc  -I. 
-I@ -I@/../include -g -mpreferred-stack-boundary=2 -fno-common 
-ffreestanding -Wall -Wredundant-decls -Wnested-externs 
-Wstrict-prototypes  -Wmissing-prototypes -Wpointer-arith -Winline 
-Wcast-qual  -ansi -c /usr/src/sys/bus/firewire/firewire.c

I thought that the reasons to use COPTFLAGS should be valid for kernel 
modules too, or am I wrong ?
