+       * 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.

+       * covariance-matrix.c (covariance_update_categorical_numeric):
+       Altered to match new code in covariance_pass_two();
+
+       * covariance-matrix.h: Fix declaration of covariance_pass_two.
+
+       * covariance-matrix.c (covariance_pass_two): Moved numeric and
+       categorical scopes of V2 inside for loop. If V1 is not
+       categorical, but V2 is, recurse with the order of the variables
+       reversed to use the code in the previous "if" scope.

+       * covariance-matrix.c (covariance_pass_two): Renamed
+       covariance_pass_one. Fixed update of covariance matrix when both
+       variables are categorical.
+       (column_iterate): New function.

+       * linreg.c (pspp_linreg): Accept a struct design_matrix.  Use new
+       accessor functions pspp_coeff_get_mean, pspp_coeff_get_sd.  New
+       functions pspp_linreg_get_indep_variable_mean,
+       pspp_linreg_set_indep_variable_mean,
+       pspp_linreg_get_indep_variable_sd,

+       pspp_coeff_set_mean, pspp_coeff_get_sd, pspp_coeff_set_sd,
