Hi,


buh# grep 'CFLAGS' /etc/make.conf
CFLAGS= -O2 -pipe

and

/usr/ports/mysql40-server# make -DBUILD_OPTIMIZED

(
buh# grep -A1 '(BUILD_OPTIMIZED' /usr/ports/databases/mysql40-server/Makefile
.if defined(BUILD_OPTIMIZED)
CFLAGS+=        -O3 -fno-omit-frame-pointer

)

result:

....
cc -c -I. -I../.././bdb/dist/../include -D_THREAD_SAFE  -DDBUG_OFF -O2 
-pipe -march=k6-2 -O3 -fno-omit-frame-pointer -fno-gcse 
../.././bdb/dist/../btree/bt_reclaim.c


Now what flag have precedence, -O2 or -O3 ?
