Really?????? That is so cool. I'd really like to know if this
was something that was part of gcc to begin with or was something
mandrake added on. Currently I am running gcc 2.95.3 and no
athlon specific stuff.

I am not sure if 'rpm --rebuild something.src.rpm --target=686" selects
good optimization options or not. If I just compile without giving
any options with gcc, it'll still build a "686 rpm" because the compiler
is hosted on a 686 platform.
Anyhow, what happens if you type in 'gcc -O2 -march=athlon' or
'gcc -O2 -march=k7' ? Do those options get recognized? If it can't
support those options, apparently you can get pretty close by compiling
for a Pentium Pro and adding a few extra flags. I can't recall all the
flags that are suggested; they'd take up a whole line or two by themselves. I
seem to recall they were documented somewhere on athlonlinux.org.
Please let me know what version of gcc is in Mandrake 8.0; I'd be interested
in verifying whether it really knows about the Athlon or not.
