GCC48 & GCC47 + FFTW-3

Also, with all gccXX ports linking against the same libgcc runtime, there should not be any incompatibility when mixing libraries between the two compilers.  You will run into issue when mixing C++ and ObjC code from the gccXX family with other compilers (as is being discussed in another thread), but as of a few weeks ago, there should be no reason that mixing +gcc47 and +gcc48 variant builds should not work.  If you just don't like having multiple compiler versions available, that's obviously a separate issue and hopefully default_variants will get updated soon =).
