@jam: Can you please take a look at this small fixup to
https://codereview.chromium.org/1345873004 ?  Without it, I get compile errors
on some embedded linux targets because errno.h hasn't been included deeper in
the include chain.

@grunell: I suppose you should have a corresponding patch in webrtc itself-
would you like me to submit such a patch?
