274    
275            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

309    
310            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
311            file; start using "Logic", hence

317    
318            * src/zpotfr.f and dependencies: use LAPACK 3.1 version
319            only needed previously to R version 2.5.0.
