9338 (make_binding_level): Use ggc_alloc_cleared or memset.
9339 (lookup_tag): Remove struct binding_level* parameter. All

9341 current_binding_level->tags if asked for thislevel_only or if
9342 we might have to diagnose "struct foo; union foo;"
9343 (pushlevel): Ignore argument. Do not push another binding
9344 level on the transition from the parameters to the top level
9345 of the function body; just tweak the flags and proceed.

9347 a function body, separate the parameter list from the
9348 top-level local variables.

9351 shadowed_tags if necessary.

9361 empty functions. Otherwise, don't call poplevel.

9393 (c_print_identifier): Update to match changes to struct
9395 (poplevel): Delete #if 0 block. Make externals invisible
9396 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9397 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9398 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9399 (duplicate-decls): For real parm decl after a forward decl,
9400 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9401 foo(...) { } with only a warning. Say whether a previous
9402 declaration was implicit.
9403 (warn_if_shadowing): Now handles all shadowing, not just
9404 local-over-local. Clarify comments.
9405 (pushdecl): Rewritten. There is no longer a distinction
9406 between global and local symbol values; they're all
9407 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9408 DECL_EXTERNAL decls, and use any_external_decl to check
9409 against previous externals. Kill #if 0 blocks. Don't
9410 tolerate error_mark_node being NULL.
9411 (pushdecl_top_level): Handle only those cases which
9412 Objective C (the only user) needs.
9413 (pushdecl_function_level): New function.
9414 (implicitly_declare): Create ordinary decls with
9415 C_DECL_IMPLICIT set. Recycle old decls, however they got
9417 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
9418 for C_DECL_INVISIBLE symbols.
9419 (lookup_name_current_level): Likewise. Use chain_member.

9423 (start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
9424 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
9425 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
9426 (identifier_global_value): Same. Must scan
9427 global_binding_level in extremis.
9429 * c-typeck.c (undeclared_variable): New static function, split
9430 from build_external_ref.
9431 (build_external_ref): Use DECL_CONTEXT, not
9432 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
9433 an instance variable. Restructure for clarity.
9434 * objc/objc-act.c: Use identifier_global_value, not
9435 IDENTIFIER_GLOBAL_VALUE.
