-// Annotate the declarations of deprecated functions with this to cause a
-// compiler warning when they're used. Like so:
-//
-//   RTC_DEPRECATED std::pony PonyPlz(const std::pony_spec& ps);
-//
-// NOTE 1: The annotation goes on the declaration in the .h file, not the
-// definition in the .cc file!
-//
-// NOTE 2: In order to keep unit testing the deprecated function without
-// getting warnings, do something like this:
-//
-//   std::pony DEPRECATED_PonyPlz(const std::pony_spec& ps);
-//   RTC_DEPRECATED inline std::pony PonyPlz(const std::pony_spec& ps) {
-//     return DEPRECATED_PonyPlz(ps);
-//   }
-//
-// In other words, rename the existing function, and provide an inline wrapper
-// using the original name that calls it. That way, callers who are willing to
-// call it using the DEPRECATED_-prefixed name don't get the warning.
-//
-// TODO(kwiberg): Remove this when we can use [[deprecated]] from C++14.
-#if defined(_MSC_VER)
-// Note: Deprecation warnings seem to fail to trigger on Windows
-// (https://bugs.chromium.org/p/webrtc/issues/detail?id=5368).
