Which is not true. Optimizing for Pentium is very stupid thing to do if your
CPU is anything but the aging Pentium.
Mandrake as well as Red Hat and Fedora are all optimized for Pentium Pro and
later CPUs.
Difference between Mdk and RHEL/RHL/FC is that Mdk has most packages shipped
as .i586.rpm (ie. can run just on i586+, optimized for i686) while most
RHEL/RHL/FC packages are .i386.rpm (ie. can run on i386+, optimized for i686).
In reality there is no real difference between -march=i386 and -march=i586 if
-mcpu=i686 is used.
