用的QT4.5.3-Embedded,打开webkit 后编译报错（如果是-no-webkit, 编译成功）：
bindings/js/JSAttrCustom.cpp: In member function 'void WebCore::JSAttr::setValue(JSC::ExecState*, JSC::JSValuePtr)':
bindings/js/JSAttrCustom.cpp:46: error: conversion from 'JSC::UString' to non-scalar type 'WebCore::String' requested
gmake[1]: *** [.obj/release-shared/JSAttrCustom.o] Error 1
