I've just installed gcc3.4 to, among other things take advantange of
the -march=opteron options. I'm in quite a bit of a conundrum here
because I've installed, changed the order in $PATH to look in
/usr/local/bin before /usr/bin for gcc, cc etc but when I run a make
buildworld it fails saying it doen't recognize the -march=opterion
option. This means that the old system version of gcc is still being
referenced somehow, even though I've set the paths:

if I rename /usr/bin/cc, I get this error now:
cc -O2 -pipe -march=opteron -nostdinc -I/usr/include -I.
-I/usr/src/sys/dev/aic7xxx/aicasm -c
/usr/src/sys/dev/aic7xxx/aicasm/aicasm.c
cc: not found
*** Error code 127
Stop in /usr/obj/usr/src/sys/GENERIC.
*** Error code 1
Stop in /usr/src.
*** Error code 1

#
so there must be something, somewhere that is hardcoding the path of
the compiler to be /usr/bin/ but I can't find where it is.
What should I do here? rename all the old compilers and symlink them
to /usr/local/bin?
