Description
QGIS should render ring as a hole in the polygon and this indeed happens with attached TAB, but not with MIF/MID.
Like this: http://gis-lab.info/images/screenshots/20130613-13f-92kb.jpg
It seems that this is not GDAL issue, but the issue is how QGIS interprets direction of nodes sequence of the ring. If outer polygon and inner are counterdirected - the ring draws, if direction is the same - it doesn't.
