I had success compiling Qt using TDM MinGW, see:
http://www.tdragon.net/recentgcc/

Here's the contents of my "configure.cache" file:
-webkit
-no-phonon
-no-dbus
-no-direct3d
-sse2
-sse
-3dnow
-mmx
-rtti
-no-vcproj
-no-dsp
-qt-libjpeg
-qt-libmng
-qt-libpng
-qt-libtiff
-qt-zlib
-no-qt3support
-qt-sql-sqlite
-debug-and-release
-opensource

Hope this helps.
