WebRTC is missing #include <stddef.h> from soundsystemproxy.cc Good test for upstreaming a patch
Committed as changeset 7b21e798ef60 Still needs upstreaming, per the whiteboard
This is reported upstream in https://webrtc-codereview.appspot.com/177001/ They rejected the patch, preferring to wait for their upstream patch to land in libjingle.
Thanks Ralph. So this isn't a great first case. :-)
