emerging audacity, fftw is brought in as a dependency, but fails to compile.

Here's the relevant output:

Sorry, I can't reproduce your problem for -march=athlon-xp - could you please check if this is arch specific?

Okay, I tried compiling it again, with exactly the same settings, and it worked fine.

I swear I changed nothing.

I blame SCO.
