Building FFTW 3.x under Visual C++/Intel compilers

Important: If you want to compile FFTW as a DLL, you should add a line #define FFTW_DLL to fftw3.h and ifftw.h before compiling. This will add the requisite __declspec decorations to function declarations etc.

Project files to compile FFTW 3.3 with Visual Studio 2010 were sent to us by Long To: fftw-3.3-libs-visual-studio-2010.zip.
