In the meantime I have been able to fetch and create Windows versions of DBus in 32- and 64-bit. The attachment contains these builds together with the appropriate expat libraries needed by DBus.

The attachment also contains the edited cc- and cls-code and the examples (private DBus server and client) that allow one to see that FindClass("DBUS") will find and return the class, although it is not in .local or .environment.

After unzipping, please follow the directions in the contained "readme.txt" file.

Please note, that I tested the 32-bit version, but short of a 64-bit Windows machine not the 64-bit, though the Makefile64 should be o.k. (I am able to create the 64-bit binaries, but not to run them on my developer machine)
