Hadrian Windows binary distributions include configure script
Under the make build system Windows binary distributions do not include a installation configure script, Makefile, or associated paraphenalia. However, it appears that Hadrian's bindist rules treat Windows binary distributions the same way they treat POSIX bindists. Consequently we end up including the configure script and Makefile, which are unnecessary on Windows.
