The following options aren't documented in 'man gcc'. So are they valid
options or what:


-mcpu is used for MIPS family of processors according to this man page.
-O6 isn't documented, so does it actually exists? Somebody told he uses
Since man gcc doesn't mention -march at all, or any 'pentiumpro' string,
how does one figure out what to use here and what the available options
