setting cflags per build

my current '/etc/makepkg.conf' is

CFLAGS="-march=athlon-xp -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

which is global for every manual build right?

but in my customised PKGBUILD
i want to take away '-fomit-frame-pointer' and then add '-g' (for debug and making good backtrace reasons)

will this do it?
'unset' to get rid of the  '-fomit-frame-pointer'

build() {
unset CFLAGS
unset CXXFLAGS
export CFLAGS="-march=athlon-xp -O2 -pipe -g"
export CXXFLAGS="-march=athlon-xp -O2 -pipe -g"

would the CFLAGS to that build be '-march=athlon-xp -O2 -pipe -g' ?

thanks, im still learning.

Re: setting cflags per build

That should work fine, yes. And you don't have to unset them, the export suffices for overwriting.
