What is the expected result?

I understand (https://groups.google.com/a/chromium.org/forum/?fromgroups=#!topic/chromium-dev/y3uHP6YbbmQ) that it should be possible to compile chromium with the 10.9 SDK.

What happens instead?

With XCode 6 Beta 2 tools (which include the 10.9 and 10.10 SDKs), compilation fails. This is because the Wifi API has changed in the 10.9 SDK.  If I compile with the XCode 5.1.1 tools (10.8 SDK) chromium compiles OK, although some of the unit tests fail under Yosemite DP2. (I will file a separate bug for that.)

Please provide any additional information below. Attach a screenshot if
possible.
