[Wien] Re: [WIEN]: Compiling using ifc 7.1 on amd

[Torsten Andersen]

I do not think (but I can be wrong, of course) the MKL libraries support 
anything older than Pentium III, and since the K6 is of the Pentium I 
type (but no MMX), you are better off going with the atlas libraries, I 
think.

Have fun,
Torsten Andersen.
