9636 (pushlevel): Ignore argument. Do not push another binding
9637 level on the transition from the parameters to the top level
9638 of the function body; just tweak the flags and proceed.

9686 (c_print_identifier): Update to match changes to struct
9688 (poplevel): Delete #if 0 block. Make externals invisible
9689 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9690 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9691 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9692 (duplicate-decls): For real parm decl after a forward decl,
9693 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9694 foo(...) { } with only a warning. Say whether a previous
9695 declaration was implicit.
9696 (warn_if_shadowing): Now handles all shadowing, not just
9697 local-over-local. Clarify comments.
9698 (pushdecl): Rewritten. There is no longer a distinction
9699 between global and local symbol values; they're all
9700 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9701 DECL_EXTERNAL decls, and use any_external_decl to check
9702 against previous externals. Kill #if 0 blocks. Don't
9703 tolerate error_mark_node being NULL.

9705 Objective C (the only user) needs.
9706 (pushdecl_function_level): New function.
9707 (implicitly_declare): Create ordinary decls with
9708 C_DECL_IMPLICIT set. Recycle old decls, however they got

9723 from build_external_ref.

9728 IDENTIFIER_GLOBAL_VALUE.
