13114 current_binding_level->tags if asked for thislevel_only or if
13115 we might have to diagnose "struct foo; union foo;"
13116 (pushlevel): Ignore argument. Do not push another binding
13117 level on the transition from the parameters to the top level
13118 of the function body; just tweak the flags and proceed.

13121 top-level local variables.

13166 (c_print_identifier): Update to match changes to struct
13168 (poplevel): Delete #if 0 block. Make externals invisible
13169 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13170 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13171 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13172 (duplicate-decls): For real parm decl after a forward decl,
13173 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

13180 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13181 DECL_EXTERNAL decls, and use any_external_decl to check
13182 against previous externals. Kill #if 0 blocks. Don't
13183 tolerate error_mark_node being NULL.

13185 Objective C (the only user) needs.
13186 (pushdecl_function_level): New function.
