6933 (pushlevel): Ignore argument. Do not push another binding
6934 level on the transition from the parameters to the top level
6935 of the function body; just tweak the flags and proceed.

6983 (c_print_identifier): Update to match changes to struct
6985 (poplevel): Delete #if 0 block. Make externals invisible
6986 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6987 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6988 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6989 (duplicate-decls): For real parm decl after a forward decl,
6990 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
6991 foo(...) { } with only a warning. Say whether a previous
6992 declaration was implicit.
6993 (warn_if_shadowing): Now handles all shadowing, not just
6994 local-over-local. Clarify comments.
6995 (pushdecl): Rewritten. There is no longer a distinction
6996 between global and local symbol values; they're all
6997 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6998 DECL_EXTERNAL decls, and use any_external_decl to check
6999 against previous externals. Kill #if 0 blocks. Don't
7000 tolerate error_mark_node being NULL.

7002 Objective C (the only user) needs.
7003 (pushdecl_function_level): New function.
7004 (implicitly_declare): Create ordinary decls with

7017 global_binding_level in extremis.
7019 * c-typeck.c (undeclared_variable): New static function, split
7020 from build_external_ref.

7025 IDENTIFIER_GLOBAL_VALUE.
