11691 (c_print_identifier): Update to match changes to struct
11693 (poplevel): Delete #if 0 block. Make externals invisible
11694 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
11695 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
11696 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
11697 (duplicate-decls): For real parm decl after a forward decl,
11698 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
