12410 we might have to diagnose "struct foo; union foo;"
12411 (pushlevel): Ignore argument. Do not push another binding
12412 level on the transition from the parameters to the top level
12413 of the function body; just tweak the flags and proceed.

12461 (c_print_identifier): Update to match changes to struct
12463 (poplevel): Delete #if 0 block. Make externals invisible
12464 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12465 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12466 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12467 (duplicate-decls): For real parm decl after a forward decl,
12468 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

12472 local-over-local. Clarify comments.

12475 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12476 DECL_EXTERNAL decls, and use any_external_decl to check
12477 against previous externals. Kill #if 0 blocks. Don't
12478 tolerate error_mark_node being NULL.

12480 Objective C (the only user) needs.
12481 (pushdecl_function_level): New function.
