Thanks Jacob , I just want to make some graphic software faster.
Cause i have a core2 cpu , supports mmx code and some other features ,
i'm trying to see if it really helps with those compiler flags.

Hi,
Is that possible to modify CFLAG for port installed software ?
I read `man mk.conf' found there's no CFLAGS or CXXFLAG entries ,
even though i tried to
put `CFLAG += -O3 -march=i686' into that file , but ports doesn't
recognize it.
Just want to optimize ports software , during compilation of
kernel , i'd comment them out.
Does anyone has any ideas ?
I've built things with '-O3 -march' on OpenBSD throughout the years.
*never* has it improved *anything*. at best, the difference is not
noticible, at worst things are slower and less stable. and I'm talking
like I did this a month ago with multimedia software that uses such
flags by default.
