The destructor of PseudoElement in Source/WebCore/dom/PseudoElement.cpp line 69 calls InspectorInstrumentation::pseudoElementDestroyed, which is only defined in Source/WebCore/inspector/InspectorInstrumentation.h line 314 surrounded by an #if USE(ACCELERATED_COMPOSITING). Adding the same macro around the call in PseudoElement.cpp fixes the wincairo build. I'll upload a patch soon.
