Just to express my happiness. The WebKit part has been merged, so every part
of Qt works now.
To compile Qt 4.7 (development version!):
Get sources from eg qt.gitorious.org/qt/qt/4.7
Get mingw-w64 from here: mingw-w64.sourceforge.net
Make sure the <mingw64>\bin folder has a copy of gmake named "mingw32-make"
in the Qt dir: configure -qt-style-windowsxp -qt-style-windowsvista -phonon
The options that still need to be provided are optional, but rely on the
presence of two headers (uxtheme.h and dshow.h), or rather the ability of
Qt's configure.exe to find them...Which it doesn't. It has already been
attempted to be fixed, I'll need to reopen the bug report then...
