+       Improvement of backtraces: Introduces a new stack narrowing
+       specifier, #t, for the inner cut.  (See further in the comments in
+       stacks.c:narrow_stack ().)
+       
+       * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
+       (Used to flag certain system procedures which shouldn't turn up in
+       backtraces.)
+
+       * eval.c (scm_sym_system_module): New symbol.  (Used to flag
+       modules which aren't "user" modules and the code of which
+       shouldn't turn up in backtraces.)
+
+       * eval.c, eval.h (scm_top_level_lookup_closure): New function:
+       Extract the lookup closure from an environment.
+       (scm_system_module_env_p): New function: Return non-#f if MODULE
+       is a system module.
+
+       * stacks.c: #include "eval.h"; #include "procprop.h";
+       (narrow_stack): Handle new narrowing specifier #t.
+
+       * debug.c (scm_procedure_name): Use name property in the default
+       case.
 
        * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
