9358 we might have to diagnose "struct foo; union foo;"
9359 (pushlevel): Ignore argument. Do not push another binding
9360 level on the transition from the parameters to the top level
9361 of the function body; just tweak the flags and proceed.

9367 shadowed_tags if necessary.

9377 empty functions. Otherwise, don't call poplevel.

9409 (c_print_identifier): Update to match changes to struct
9411 (poplevel): Delete #if 0 block. Make externals invisible
9412 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9413 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9414 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9415 (duplicate-decls): For real parm decl after a forward decl,
9416 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9417 foo(...) { } with only a warning. Say whether a previous
9418 declaration was implicit.
9419 (warn_if_shadowing): Now handles all shadowing, not just
9420 local-over-local. Clarify comments.
9421 (pushdecl): Rewritten. There is no longer a distinction
9422 between global and local symbol values; they're all
9423 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9424 DECL_EXTERNAL decls, and use any_external_decl to check
9425 against previous externals. Kill #if 0 blocks. Don't
9426 tolerate error_mark_node being NULL.

9428 Objective C (the only user) needs.
9429 (pushdecl_function_level): New function.
9430 (implicitly_declare): Create ordinary decls with
9431 C_DECL_IMPLICIT set. Recycle old decls, however they got
9433 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
9434 for C_DECL_INVISIBLE symbols.
9435 (lookup_name_current_level): Likewise. Use chain_member.
