Unrelated with GDAL 1.8.0. The issue was that the transformation between OGC 
WKT and ESRI WKT didn't handle well the Oblique Stereographic projection. 
Fixed in trunk in http://trac.osgeo.org/gdal/changeset/21627

When those 2 new options are used, they imply creating a new dataset. So they 
actually need to be used with -tr or -ts option.
