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...
