9105 we might have to diagnose "struct foo; union foo;"
9106 (pushlevel): Ignore argument. Do not push another binding
9107 level on the transition from the parameters to the top level
9108 of the function body; just tweak the flags and proceed.

9156 (c_print_identifier): Update to match changes to struct
9158 (poplevel): Delete #if 0 block. Make externals invisible
9159 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9160 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9161 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9162 (duplicate-decls): For real parm decl after a forward decl,
9163 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9164 foo(...) { } with only a warning. Say whether a previous
9165 declaration was implicit.

9167 local-over-local. Clarify comments.
9168 (pushdecl): Rewritten. There is no longer a distinction
9169 between global and local symbol values; they're all
9170 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9171 DECL_EXTERNAL decls, and use any_external_decl to check
9172 against previous externals. Kill #if 0 blocks. Don't
9173 tolerate error_mark_node being NULL.

9175 Objective C (the only user) needs.
9176 (pushdecl_function_level): New function.
9177 (implicitly_declare): Create ordinary decls with

9198 IDENTIFIER_GLOBAL_VALUE.
