FFTW is a C subroutine library for computing the Discrete Fourier Transform
(DFT) in one or more dimensions, of both real and complex data, and of
arbitrary input size. We believe that FFTW, which is free software, should
become the FFT library of choice for most applications. Our benchmarks,
performed on a variety of platforms, show that FFTW's performance is
typically superior to that of other publicly available FFT software.
Moreover, FFTW's performance is portable: the program will perform well on
most architectures without modification.
The FFTW package was developed at MIT by Matteo Frigo and Steven G.
Johnson. Please send email to fftw@theory.lcs.mit.edu so that we can keep
track of users and send you information about new releases. The latest
version of FFTW, benchmarks, links, and other information can be found at
the FFTW home page.
===> The following configuration options are available for fftw3-long-3.3.11:
G77_WRAPPERS=off: Alter Fortran wrappers for use with g77
OPENMP=on: Build OpenMP multi-threaded libraries
OPENMPI=off: Build OpenMPI parallel libraries
OPTIMIZED_CFLAGS=on: Use extra compiler optimizations
SIMD=on: Use CPU-specific optimizations
===> Use 'make config' to modify these settings
math: remove 'Created by' lines

- update fftw3* to 3.3 [1], and adjust dependent ports
- make use of optimizations by default, where possible
(quad flavor to follow shortly, and mpi at a later date)
Suggestions and patches from: ache, C. Burns, wen
- After digging into the Makefile and configure for fftw3 I discovered
that USE_FORTRAN was only used to determine what name mangling scheme
it had to use to compile the shim libs for fortran, but compiling everything
using 'C' anyway.
With this diff, the slave ports fftw3-long-fortran, fftw3-float-fortran
and fftw3-fortran disapear since the shims are always built, without
necessitating the use of a USE_FORTRAN.

- Ensure Fortran shim is not built if USE_FORTRAN is not set.
- Split Fortran option into slave ports fftw3-fortran long-fortran float-fortran
- Have to bump PORTREVISION for package builds etc..
- Fix silly spelling mistakes "Percision" -> "Precision" noted.

- Fix build for 4.x users who define WITH_OPTIMIZED_CFLAGS and have SSE by
using internal libtool since we use gcc34 and libtool15 doesn't like a
different CC/CXX other than the one it was built with [1]
- Fix plist if WITH_SMP_THREADS was defined
- Bump PORTREVISION to force update of plist changes

Add slave port fftw3-float
Fast C routines (Single Percision)
Add slave port fftw3-long
Fast C routines (Long Double Percision)
