375            * R/sparseMatrix.R: apply the above
376    
377            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
378    
379            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
380            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of

387            as_Csparse(.) way.
