qgraphicswebview.cpp not compiling due to -Werror and QWebPageClient.h

Not sure about the component, but here goes:

GCC 4.3.1 on openSuSE Linux 11.0
configure options: -no-script -no-scripttools -fast -shared -release -qtlibinfix XXXX -commercial -nomake demos -nomake examples -openssl -no-phonon -no-multimedia -no-accessibility -no-xinerama -prefix /opt/qt/4_8_0 -I /opt/openssl/1.0.0g/include/ -L /opt/openssl/1.0.0g/lib/ -webkit -qt-libjpeg -qt-libpng -qt-libtiff -qt-zlib -qt-libmng

When compiling src/3rdparty/webkit/Source/WebKit/qt/Api/qgraphicswebview.cpp, gcc gives the following error:

cc1plus: warnings being treated as errors
In file included from WebCoreSupport/PageClientQt.h:28,
                 from Api/qgraphicswebview.cpp:31:
../../WebCore/platform/qt/QWebPageClient.h:56: error: unused parameter layer
../../WebCore/platform/qt/QWebPageClient.h:61: error: unused parameter scheduleSync

This is due to:

virtual void setRootGraphicsLayer(WebCore::PlatformLayer\* layer) { }
virtual void markForSync(bool scheduleSync = false) { } 

So I'm going to work around it by removing the -Werror option. Please fix.
