[Dune] Dune on Windows MinGW

[Martin Nolte]

Hi Olaf,

thanks a lot for the patch. I just committed a slight variant (still having
the method and including correct headers). We should notice that the man-pages
decourage the use of this function though (maybe due to not opening the file).

Best,

Martin
