The name change was done using #define QXmlStreamWriter QCoreXmlStreamWriter
There is a comment saying it was done using typedef, but apparently it was 
not. http://code.woboq.org/kde/qt4/src/corelib/xml/qxmlstream.h.html
So compatibility was not broken (but there was ugly macro)

I think this prove that this is possible.

(And for forward declaration, i think we should have header with them and 
forbid them)
