+* The new signal handling code has been tweaked to treat register
+  contents as (UNSIGNED-BYTE 32), as the old CMU CL code did,
+  instead of (SIGNED-BYTE 32), as the C header files have it. (Code 
+  downstream, e.g. in debug-int.lisp, has implicit dependencies
+  on the unsignedness of integer representation of machine words, 
+  and that caused the system to bomb out with infinite regress
+  when trying to recover from type errors involving signed values,
+  e.g. (BUTLAST '(1 2 3) -1).)
