[Nix-dev] fftw-3.2.2 impurity

[Peter Simons]

Hi,

I noticed that fftw-3.2.2 is built using the compiler flag "-march=native".
This is bad, because it means that the build machine determines the nature of
the resulting binaries. I won't be able to investigate (or fix) this problem in
the near future, so I reckoned I'd let you guys know in case anyone cares a lot
about the usability of that library.

Take care,
Peter
