+// 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.
