That's not true; it adds -mcpu=pentiumpro by default to optimize instruction scheduling for 686-class CPUs (without breaking binary compatibility down to i386s), but it doesnt "autodetect" anything, and you'll get better performance on a 686-class CPU by specifying it in CPUTYPE (since you'll then also get pentium pro instructions). -mcpu != -march Kris
