4821 we might have to diagnose "struct foo; union foo;"
4822 (pushlevel): Ignore argument. Do not push another binding
4823 level on the transition from the parameters to the top level
4824 of the function body; just tweak the flags and proceed.

4827 top-level local variables.

4830 shadowed_tags if necessary.

4840 empty functions. Otherwise, don't call poplevel.

4872 (c_print_identifier): Update to match changes to struct
4874 (poplevel): Delete #if 0 block. Make externals invisible
4875 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
4876 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
4877 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
4878 (duplicate-decls): For real parm decl after a forward decl,
4879 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
4880 foo(...) { } with only a warning. Say whether a previous
4881 declaration was implicit.
4882 (warn_if_shadowing): Now handles all shadowing, not just
4883 local-over-local. Clarify comments.
4884 (pushdecl): Rewritten. There is no longer a distinction
4885 between global and local symbol values; they're all
4886 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
4887 DECL_EXTERNAL decls, and use any_external_decl to check
4888 against previous externals. Kill #if 0 blocks. Don't
4889 tolerate error_mark_node being NULL.

4891 Objective C (the only user) needs.
4892 (pushdecl_function_level): New function.
4893 (implicitly_declare): Create ordinary decls with
4894 C_DECL_IMPLICIT set. Recycle old decls, however they got
4896 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
4897 for C_DECL_INVISIBLE symbols.
4898 (lookup_name_current_level): Likewise. Use chain_member.
