9583 current_binding_level->tags if asked for thislevel_only or if
9584 we might have to diagnose "struct foo; union foo;"
9585 (pushlevel): Ignore argument. Do not push another binding
9586 level on the transition from the parameters to the top level
9587 of the function body; just tweak the flags and proceed.

9635 (c_print_identifier): Update to match changes to struct
9637 (poplevel): Delete #if 0 block. Make externals invisible
9638 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9639 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9640 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9641 (duplicate-decls): For real parm decl after a forward decl,
9642 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9643 foo(...) { } with only a warning. Say whether a previous
9644 declaration was implicit.
9645 (warn_if_shadowing): Now handles all shadowing, not just
9646 local-over-local. Clarify comments.
9647 (pushdecl): Rewritten. There is no longer a distinction
9648 between global and local symbol values; they're all
9649 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9650 DECL_EXTERNAL decls, and use any_external_decl to check
9651 against previous externals. Kill #if 0 blocks. Don't
9652 tolerate error_mark_node being NULL.

9654 Objective C (the only user) needs.
9655 (pushdecl_function_level): New function.
9656 (implicitly_declare): Create ordinary decls with
