609 current_binding_level->tags if asked for thislevel_only or if
610 we might have to diagnose "struct foo; union foo;"
611 (pushlevel): Ignore argument. Do not push another binding
612 level on the transition from the parameters to the top level
613 of the function body; just tweak the flags and proceed.
614 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
615 a function body, separate the parameter list from the
616 top-level local variables.
617 (set_block): Do nothing.

619 shadowed_tags if necessary.

663 (poplevel): Delete #if 0 block. Make externals invisible
664 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
665 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
666 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
667 (duplicate-decls): For real parm decl after a forward decl,
668 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
669 foo(...) { } with only a warning. Say whether a previous
670 declaration was implicit.
671 (warn_if_shadowing): Now handles all shadowing, not just
672 local-over-local. Clarify comments.
673 (pushdecl): Rewritten. There is no longer a distinction
674 between global and local symbol values; they're all
675 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
676 DECL_EXTERNAL decls, and use any_external_decl to check
677 against previous externals. Kill #if 0 blocks. Don't
678 tolerate error_mark_node being NULL.

680 Objective C (the only user) needs.

695 global_binding_level in extremis.
697 * c-typeck.c (undeclared_variable): New static function, split
698 from build_external_ref.
699 (build_external_ref): Use DECL_CONTEXT, not
700 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
