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

806 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
807 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
808 (duplicate-decls): For real parm decl after a forward decl,
809 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
810 foo(...) { } with only a warning. Say whether a previous
811 declaration was implicit.
812 (warn_if_shadowing): Now handles all shadowing, not just
813 local-over-local. Clarify comments.
814 (pushdecl): Rewritten. There is no longer a distinction
815 between global and local symbol values; they're all
816 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
817 DECL_EXTERNAL decls, and use any_external_decl to check
818 against previous externals. Kill #if 0 blocks. Don't

836 global_binding_level in extremis.
838 * c-typeck.c (undeclared_variable): New static function, split
839 from build_external_ref.
840 (build_external_ref): Use DECL_CONTEXT, not
