I thought -Os was considered to be the opposite of aggressive?
The manual suggests that it's kind of like -O2 but with any tests that
generate bulky code turned off.
Usually the boys trying to knock holes in gentoo pick out the -Os flag
and claim that we should all use that rather than -O2/-O3 because it
would make things faster...
