12414 we might have to diagnose "struct foo; union foo;"
12415 (pushlevel): Ignore argument. Do not push another binding
12416 level on the transition from the parameters to the top level
12417 of the function body; just tweak the flags and proceed.

12465 (c_print_identifier): Update to match changes to struct
12467 (poplevel): Delete #if 0 block. Make externals invisible
12468 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12469 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12470 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12471 (duplicate-decls): For real parm decl after a forward decl,
12472 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

12476 local-over-local. Clarify comments.

12478 between global and local symbol values; they're all
12479 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12480 DECL_EXTERNAL decls, and use any_external_decl to check
12481 against previous externals. Kill #if 0 blocks. Don't
12482 tolerate error_mark_node being NULL.

12484 Objective C (the only user) needs.
12485 (pushdecl_function_level): New function.
