+	* linreg.c (post_sweep_computations): New function to re-use the
+	re-usable. New function cache_init() to re-use the re-usable. 
+	pspp_linreg_with_cov() now estimates parameters via reg_sweep().

+
+	* linreg.c (pspp_linreg_with_cov): New function to estimate
+	parameters directly from covariance matrix instead of using the
+	entire data set.
+
+	* linreg.c (rearrange_covariance_matrix): New function to ensure
+	the columns of the covariance matrix correspond to the variables
+	in the model.

+
+	* merge.c merge.h sort.c sort.h: Removed the value_cnt associated
+	with case ordering.  This ensures that the casereader returned by
+	sort_execute now has the same dimensions as the casereader passed 
+	in.
