It says this, but it seems it lies:

  /* The system prototypes for these functions have many
     variations, so don't specify parameters to avoid conflicts.
     The expand_* functions check the argument types anyway.  */
  builtin_function_2 ("__builtin_bzero", "bzero",
                      bzero_ftype, void_ftype_any,
                      BUILT_IN_BZERO, BUILT_IN_NORMAL, 1, 1, 0);

The prototype is:

  /* Prototype for bzero.  */
  bzero_ftype
    = build_function_type (void_type_node,
                           tree_cons (NULL_TREE, traditional_ptr_type_node,
                                      traditional_len_endlink));

traditonal_ptr_type_node is what strlen uses.  traditional_len_endlink
refers to "int".  My guess is it wants:

	void bzero (char *, int);

As far as whether or not it's a bug, and/or how to shut it up
portably, probably best to ask on gcc AT gcc DOT gnu DOT org.
