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

832 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
833 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
834 (duplicate-decls): For real parm decl after a forward decl,
835 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
836 foo(...) { } with only a warning. Say whether a previous
837 declaration was implicit.
838 (warn_if_shadowing): Now handles all shadowing, not just
839 local-over-local. Clarify comments.
840 (pushdecl): Rewritten. There is no longer a distinction
841 between global and local symbol values; they're all
842 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
843 DECL_EXTERNAL decls, and use any_external_decl to check
844 against previous externals. Kill #if 0 blocks. Don't

862 global_binding_level in extremis.
864 * c-typeck.c (undeclared_variable): New static function, split
865 from build_external_ref.
866 (build_external_ref): Use DECL_CONTEXT, not
