Does anybody know what the `-O3' and `-O4' flags do when passed to cc?  Do
these cause some additional optimization beyond that done by `-O' to be
done?  I have seen these flags used in various programs from the source
archives but have not seen any documentation on them.  I have a 3/260
running OS 3.5 but only a 3.2 manual set.
