As you said, there were no problems with platforms other than Windows.
However, as mentioned in the bug issue, on Windows, symbolic links are not supported and the contents of some files like "ADDITIONAL_LICENSE_INFO" are not included in the generated documentation. This fix will ensure that the contents of the files are reliably included  in the generated documentation.
