That's why for the moment I just added '-tpp6' and not '-axK' for instance 
because the latter is pentium III specific (tpp6 is valid from the pentium 
pro onward)

For the -axK I should take a look at what they're doing for the mipspro, 
using <architecture> etc. as suggested by Rene.

Yep : 6.0.
I did'nt see it in the documentation that it's on by default but I did notice 
the difference ?
