It's never a good idea to do an installworld before building (and installing)
the new kernel. Don't do this. I think you are referring to the 20040728
entry in UPDATING, which reads:
With the upgrade of the system compiler, the kernel has been upgraded
to match the new system compiler. This makes it impossible to build
a new kernel with the old compiler. Upgrade your system via
make buildworld and make kernel (see below) to fix this problem.
This clearly states that you *can* build the kernel *after* you do a make
buildworld. It does *not* say you have to do an installworld.
