+    These are tentative new GetColumns members which should be more database
+    independent and which always returns the columns in the order they were
+    created.
+
+    - The first one (wxDbColInf *wxDb::GetColumns(wxChar *tableName[], const
+      wxChar* userID)) calls the second implementation for each separate table
+      before merging the results. This makes the code easier to maintain as
+      only one member (the second) makes the real work
+    - wxDbColInf *wxDb::GetColumns(const wxString &tableName, int *numCols, const
+      wxChar *userID) is a little bit improved
+    - It doesn't anymore rely on the type-name to find out which database-type
+      each column has
+    - It ends by sorting the columns, so that they are returned in the same
+      order they were created
