Cannot recompile on Windows, undefined reference to `__getreent’

I’m trying to use Qt on Windows. I found that the Windows binaries are built without rtti enabled. I cannot use them to build the diagram example in chapter 8 of the Qt book (C++ Gui programming with Qt4) because of the lack of rtti. So I am trying to rebuild with rtti enabled.

But I cannot build, I get a lot of undefined references to __getreent. Can anyone advise what to do?
