6073 (pushlevel): Ignore argument. Do not push another binding
6074 level on the transition from the parameters to the top level
6075 of the function body; just tweak the flags and proceed.

6123 (c_print_identifier): Update to match changes to struct
6125 (poplevel): Delete #if 0 block. Make externals invisible
6126 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6127 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6128 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6129 (duplicate-decls): For real parm decl after a forward decl,
6130 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
6131 foo(...) { } with only a warning. Say whether a previous
6132 declaration was implicit.
6133 (warn_if_shadowing): Now handles all shadowing, not just
6134 local-over-local. Clarify comments.
6135 (pushdecl): Rewritten. There is no longer a distinction
6136 between global and local symbol values; they're all
6137 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6138 DECL_EXTERNAL decls, and use any_external_decl to check
6139 against previous externals. Kill #if 0 blocks. Don't
6140 tolerate error_mark_node being NULL.

6142 Objective C (the only user) needs.
6143 (pushdecl_function_level): New function.
6144 (implicitly_declare): Create ordinary decls with

6157 global_binding_level in extremis.
6159 * c-typeck.c (undeclared_variable): New static function, split
6160 from build_external_ref.
6161 (build_external_ref): Use DECL_CONTEXT, not

6165 IDENTIFIER_GLOBAL_VALUE.
