         * Reorganized signal names in kill.c for better architecture support 
             -- patch thanks to simon wood <simon@mungewell.uklinux.net>
+        * In 0.43, backspace and delete worked properly, but with 0.45, 
+            it just echoed a ^? for backspace, and ^H for control-h.  This
+            was due to a broken macro in init.c, that is now fixed.
