// In libavcodec/fft_template.c, fft initialization happens via if statements
// checked on preprocessor defines. On many platforms, these statements are
// culled during compilation. However, in situations where optimization is
// disabled on windows visual studio (PGO, using --disable-optimization in
// mozconfig, etc), these branches are still compiled, meaning we end up with
// linker errors due calls to undefined functions. The dummy functions in this
// file provide bodies so that the library will link in that case, even though
// these will never be called.
