8300 we might have to diagnose "struct foo; union foo;"
8301 (pushlevel): Ignore argument. Do not push another binding
8302 level on the transition from the parameters to the top level
8303 of the function body; just tweak the flags and proceed.

8351 (c_print_identifier): Update to match changes to struct
8353 (poplevel): Delete #if 0 block. Make externals invisible
8354 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8355 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8356 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8357 (duplicate-decls): For real parm decl after a forward decl,
8358 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
8359 foo(...) { } with only a warning. Say whether a previous
8360 declaration was implicit.

8362 local-over-local. Clarify comments.
8363 (pushdecl): Rewritten. There is no longer a distinction
8364 between global and local symbol values; they're all
8365 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
8366 DECL_EXTERNAL decls, and use any_external_decl to check
8367 against previous externals. Kill #if 0 blocks. Don't
8368 tolerate error_mark_node being NULL.

8370 Objective C (the only user) needs.
8371 (pushdecl_function_level): New function.
8372 (implicitly_declare): Create ordinary decls with

8393 IDENTIFIER_GLOBAL_VALUE.
