It's difficult to review this patch without context. Wouldn't PLATFORM(CHROMIUM) re-use one of the existing accessibility implementations depending on the platform (MSAA, ATK etc.)? If this patch is simply a build fix, you may be better served by looking for a way to disable accessibility in your port for now, for example using ENABLE(ACCESSIBILITY). Not marking r- but this one needs some clarification from the submitter.

Hi Alp.  Thanks for the great question.  It turns out that using traditional a11y APIs directly from the sandboxed chromium renderer simply doesn't work.  We have to marshal everything out of the sandbox.  This is best accomplished using platform independent code, so for us the AccessibilityObjectWrapper really shouldn't be COM or ATK or any other platform specific technology.  Does that make sense?

Looks sane enough.
