678 current_binding_level->tags if asked for thislevel_only or if
679 we might have to diagnose "struct foo; union foo;"
680 (pushlevel): Ignore argument. Do not push another binding
681 level on the transition from the parameters to the top level
682 of the function body; just tweak the flags and proceed.
683 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
684 a function body, separate the parameter list from the
685 top-level local variables.
686 (set_block): Do nothing.

688 shadowed_tags if necessary.

698 empty functions. Otherwise, don't call poplevel.

732 (poplevel): Delete #if 0 block. Make externals invisible
733 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
734 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
735 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
736 (duplicate-decls): For real parm decl after a forward decl,
737 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
738 foo(...) { } with only a warning. Say whether a previous
739 declaration was implicit.
740 (warn_if_shadowing): Now handles all shadowing, not just
741 local-over-local. Clarify comments.
742 (pushdecl): Rewritten. There is no longer a distinction
743 between global and local symbol values; they're all
744 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
745 DECL_EXTERNAL decls, and use any_external_decl to check
746 against previous externals. Kill #if 0 blocks. Don't
747 tolerate error_mark_node being NULL.

749 Objective C (the only user) needs.
750 (pushdecl_function_level): New function.
751 (implicitly_declare): Create ordinary decls with

755 for C_DECL_INVISIBLE symbols.
756 (lookup_name_current_level): Likewise. Use chain_member.
757 (c_make_fname_decl): Don't muck with DECL_CONTEXT.

760 (start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
761 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
762 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.

764 global_binding_level in extremis.
766 * c-typeck.c (undeclared_variable): New static function, split
767 from build_external_ref.
768 (build_external_ref): Use DECL_CONTEXT, not
769 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides

772 IDENTIFIER_GLOBAL_VALUE.
