13119 current_binding_level->tags if asked for thislevel_only or if
13120 we might have to diagnose "struct foo; union foo;"
13121 (pushlevel): Ignore argument. Do not push another binding
13122 level on the transition from the parameters to the top level
13123 of the function body; just tweak the flags and proceed.

13126 top-level local variables.

13171 (c_print_identifier): Update to match changes to struct
13173 (poplevel): Delete #if 0 block. Make externals invisible
13174 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13175 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13176 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13177 (duplicate-decls): For real parm decl after a forward decl,
13178 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

13185 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13186 DECL_EXTERNAL decls, and use any_external_decl to check
13187 against previous externals. Kill #if 0 blocks. Don't
13188 tolerate error_mark_node being NULL.

13190 Objective C (the only user) needs.
13191 (pushdecl_function_level): New function.
