Modifying CFLAGS for fstack-protector-strong

Stupid question perhaps, but according to this ML post, Allan plans to modify /etc/makepkg.conf to use this new flag.  Now that gcc-4.9-1 is in [core], I thought I would get ahead of the curve. 

1) Is this the correct syntax?

CFLAGS="-march=native -O2 -pipe -fstack-protector-strong --param=ssp-buffer-size=4"

2) Is there another modification to the file as well?

Thanks.

EDIT: Should probably mention that I checked in git but found no commit that would answer my question.

Yes, that's the correct syntax, and there should be no other changes needed AFAIK.

Edit, other than changing CXXFLAGS, too, of course.

Thanks, Scimmia.  I just redirect:

CFLAGS="-march=native -O2 -pipe -fstack-protector-strong --param=ssp-buffer-size=4"
CXXFLAGS="${CFLAGS}"
