799 (pushlevel): Ignore argument. Do not push another binding
800 level on the transition from the parameters to the top level
801 of the function body; just tweak the flags and proceed.

803 a function body, separate the parameter list from the
804 top-level local variables.

853 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
854 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
855 (duplicate-decls): For real parm decl after a forward decl,
856 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
857 foo(...) { } with only a warning. Say whether a previous
858 declaration was implicit.
859 (warn_if_shadowing): Now handles all shadowing, not just
860 local-over-local. Clarify comments.
861 (pushdecl): Rewritten. There is no longer a distinction
862 between global and local symbol values; they're all
863 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
864 DECL_EXTERNAL decls, and use any_external_decl to check
865 against previous externals. Kill #if 0 blocks. Don't
866 tolerate error_mark_node being NULL.

868 Objective C (the only user) needs.

883 global_binding_level in extremis.
885 * c-typeck.c (undeclared_variable): New static function, split
886 from build_external_ref.
887 (build_external_ref): Use DECL_CONTEXT, not
888 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
