Make sure you are not using mingw, but mingw-w64. mingw is more or less dead nowadays.

My recommendation is to use the mingw-w64 packaged in the latest Qt SDK. There is a Qt-builds project as well other than the mingw builds. That is run by the mingw-builds team. They have proper scripts to build all of Qt, QtCreator, and so forth.

Here you can find them (develop branch):

That being said, you can grab the latest for today with mingw, too:
