GCC48 & GCC47 + FFTW-3

[David Strubbe]

Let me just comment: I am not sure there is any reason to try to swap
everything from gcc47 to gcc48. There are probably only a few cases where
there would be some incompatibility (and likely only at build time), and so
Federico could just rebuild ports insofar as any problem is found.
