There is already a working binary snapshot of dbus-win32 containing a libdbus-1. See \
http://lists.freedesktop.org/archives/dbus/2006-May/004755.html

It needs some update for the latest qtDBus changes.

which will be required for windows. I think currently dbus-win32 will be 
distributed as separate package, later may be as gnuwin32 package.
