Pietro, In GDAL 1.10, Update is available as OGR_L_Update ( http://www.gdal.org/ogr/ogr__api_8h.html#a87b478c971619145dee7d8d8deeac702 ) . This can be for example used from the Python script at http://svn.osgeo.org/gdal/trunk/gdal/swig/python/samples/ogr_layer_algebra.py Eliminate has no direct equivalent in GDAL, AFAIK. At first sight, the algorithm could likely be coded with the operations on geometry already available in the OGRGeometry class (Intersection, Length, Area).
