Q_ORGANIZER_EXPORT is undefined

Today (Feb 23) I updated my Qt SDK and application that uses QOrganizer API started to generate compile errors. This was the first time I used "Help -> Start updater" feature. I get the following error messages:

C:/Qt/QtSDK/Symbian/SDKs/Symbian3Qt471/epoc32/include/app/qorganizeritemdetail.h:62: error: 'Q_ORGANIZER_EXPORT' does not name a type

My workaround was to add:

#define Q_ORGANIZER_EXPORT

line to:

C:/Qt/QtSDK/Symbian/SDKs/Symbian3Qt471/epoc32/include/app/qorganizeritemdetail.h

and to

C:/Qt/QtSDK/Symbian/SDKs/Symbian3Qt471/epoc32/include/app/qorganizeritemid.h

Then building was possible again. I'm pretty sure that this was not the right way to fix the situation..
