Geez -- is that enough flags? -- why couldn't they just have a -m686?
Sigh. Under optflags, the first thing you have is "i686". Is that a
flag: should it have a "-" in front of it? Thanks for the great info!
Now the 786=PII, and the 868=PIII? I assume no one has started
optimizing for those yet?
Thanks (merci) again!
