Q_WS_S60 is not going to be defined for Symbian^4 devices as Q_WS_S60 used to guard Avkon UI framework dependencies (see http://doc.qt.nokia.com/4.7-snapshot/qtglobal.html#Q_WS_S60). Going trough all the usage of Q_WS_S60 in WebKit I have found that all of them really should have been Q_OS_SYMBIAN. Patch will follow.
