You don't need to do that I think.
The text is confusing but what I think
they meant was that with this option on,
very minor changes to code could make large changes
to the executable, making it impossible
to fine tune programs (which is usually required
in a realtime environment).

You could sent a patch to gcc-patches with
non confusing text?
