I don't see fftw package in the lists below.
Did it build successfully for you in both 4.8 and 4.7.2-9,
or did it fail in both?

I ask because it currently fails to build in koji
and brew (logs show gcc-4.8.0 is in use):
see failed fftw-3.3.3-6.fc19 and fftw-3.3.3-6.el7 builds.

But it used to build just fine before in both.
I tried a local build on F18 where I have gcc-4.7.2-8
and it succeeded too.
(How I tested: fedpkg clone fftw; cd fftw; fedpkg local)

The build fails not in the compilation per se, but in testsuite
which runs as part of the build. In scratch build I
