DESCRIPTION: we enter two PARTITIONobjects gross and klein,
where gross is the bigger one. The result becomes a
SKEWPARTITIONobject. The difference is as in all the other cases.
Using the routine b_gk_spa the input becomes part of the
SKEWPARTITIONobject, while with m_gk_spa we have a copy of the
input in the result.
