Yes, it seems strange.

More about my configuration, and the order of installation:

Windows XP SP3
Visual Studio 6

about two months ago, I installed
QT 4.5.2 SDK


A few days ago (after the QT developer days in Munich), I downloaded QT 4.6.0 beta 1, which includes MinGW. I uninstalled 4.5.2 and installed 4.6.0 beta 1
I also downloaded Creator 1.3.0 beta, and since that's only available in source, I built it using MinGW.
I then realized I might want to have an official SDK installed, and downloaded and installed 4.5.3 SDK, which includes Creator 1.2

Then came all the trouble on the command line. During that time, I tried JOM as an alternative to MinGW. I tried nmake before that, but it seems the Visual Studio 6 version is outdated, and can't compile certain stuff.

Then I fixed that command line trouble (THANKS!), but now still got error messages in Creator 1.3.0 beta.

This is my full output when building AnimatedTiles with command line (qmake and jom):
