7 Yes, that's right. These flags don't need to be set again. But there are
8 some ebuilds that filter certain flags like march. By this filtering the
9 package would be compiled without mmx and msse2 if the flags aren't set
10 again. If they are, the package will still be compiled *with* mmx and
11 msse2 even though march is filtered.. Yes, the filtering in the ebuild
12 isn't done just for fun but some people still prefer to have mmx and
13 msse2 enabled (when march is filtered).
14 In short, settings these flags is not completley stupid but has a reason
15 (even though it's not a very good one). :)

19 Why? I have a complete system running with -Os here and it's working fine.
