The windows-only WebKitClassFactory.cpp class links to the SAFARI_THEME library. This is a problem if you want to build a Cario-backed version of WebKit since it requires CoreGraphics to work. Someday, the themes will be standardized under a more modular infrastructure, but until then a reasonable work-around is to not link to SAFARI_THEME when the "USE(SAFARI_THEME)" test fails.
