looking inside a few of the rpms from linux-mandrake 6.0
[http://www.linux-mandrake.com] (excellent work i must say) with

rpm --showrc  xxx.i586.rpm

it appears as though most packages i queried use -O2 for opt levels. 
wouldn't it be better to use -O6 instead?

also, it seems that

echo 'optflags: i386 -O6 -mpentiumpro -march=pentiumpro
-fomit-frame-pointer' > /etc/rpmrc

does not always pass these options during

rpm --rebuild xxx.src.rpm

any tips?  i'm pretty much a beginner at this.  my apologies if this is
not the correct forum.
