/* Defines complex types that are bit compatible with C99's complex.h
 * and (crucially) the same type as expected by fftw3.h.
 * Note, don't use this with complex.h. fftw3.h checks to see whether
 * complex.h is included and then uses that to set the interface.
 * Since MSVC doesn't support C99, by using the following types we
 * have a cross platform/compiler solution.
