Datutil is unable to create the dat-file for this version of mame.
Fortunately Barry Harris has identified the problem and has fixed it.
You can read about the problem and grab the new binary on his site. http://www.barryharris.me.uk/article_view.php?id=176
With thanks to Anime-niac for directing me to Barry Harris fix and off course Barry Harris.
