Compiling kernel with gcc43

I followed the instructions from
to see if I can achieve some performance gain (8-STABLE r205630 amd64) and
also get a more modern instruction set for my Phenom II (amdfam10), so I've
done the following config settings:
.if !empty(.CURDIR:M/usr/ports/*) && exists(/usr/local/bin/gcc43)
buildworld goes on normally it seems, but when I tried to build the kernel,
the first stop came from the option used by the kernel build "-fformat-
extensions", which is not accepted by gcc43, so I took it out of
/usr/src/sys/conf/kern.mk, the ONLY place I found it.
It seemed to solve the problem until gcc43 stopped because of the "-Werror"
option, which is all over the place!. Funny that gcc42 (used by default)
doesn't stop because of this option.
Anyway,my question boils down to: Is there a way to build the kernel with
gcc43, with minimal tweaking? Am i attempting something out of my league?
