I am trying this last 3 days to compile Qt with MinGW using this configuration:
Qt Code: 
  1. C:\qt-4.7.1>configure -no-opengl -no-qt3support -opensource -release -shared -no-dbus -no-openvg -platform win32-g++ -qt-zlib -qt-libpng
  2. -libjpeg -qmake -no-multimedia  -no-audio-backend   -no-webkit -no-phonon -nomake examples -nomake demos -no-style-motif -no-style-cde -
  3. tyle-cleanlooks -no-style-plastique

But I fail with this error every time:
