9112 we might have to diagnose "struct foo; union foo;"
9113 (pushlevel): Ignore argument. Do not push another binding
9114 level on the transition from the parameters to the top level
9115 of the function body; just tweak the flags and proceed.

9163 (c_print_identifier): Update to match changes to struct
9165 (poplevel): Delete #if 0 block. Make externals invisible
9166 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9167 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9168 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9169 (duplicate-decls): For real parm decl after a forward decl,
9170 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9171 foo(...) { } with only a warning. Say whether a previous
9172 declaration was implicit.
9173 (warn_if_shadowing): Now handles all shadowing, not just
9174 local-over-local. Clarify comments.
9175 (pushdecl): Rewritten. There is no longer a distinction
9176 between global and local symbol values; they're all
9177 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9178 DECL_EXTERNAL decls, and use any_external_decl to check
9179 against previous externals. Kill #if 0 blocks. Don't
9180 tolerate error_mark_node being NULL.

9182 Objective C (the only user) needs.
9183 (pushdecl_function_level): New function.
9184 (implicitly_declare): Create ordinary decls with

9205 IDENTIFIER_GLOBAL_VALUE.
