938 (clear_binding_level, lookup_tag_reverse): Kill.
939 (make_binding_level): Use ggc_alloc_cleared or memset.
940 (lookup_tag): Remove struct binding_level* parameter. All
941 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
942 current_binding_level->tags if asked for thislevel_only or if
943 we might have to diagnose "struct foo; union foo;"
944 (pushlevel): Ignore argument. Do not push another binding
945 level on the transition from the parameters to the top level
946 of the function body; just tweak the flags and proceed.
947 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
948 a function body, separate the parameter list from the
949 top-level local variables.
950 (set_block): Do nothing.
951 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
952 shadowed_tags if necessary.

956 an older decl in the same binding level.

959 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
960 (start_function): Don't set subblocks_tag_transparent.
961 (finish_function): Fix up the binding_level stack for totally
962 empty functions. Otherwise, don't call poplevel.
964 * c-common.c (shadow_warning): MANDATORY argument is no longer
965 necessary. Always use plain warning.
966 * c-common.h: Update to match.
968 * cfglayout.c (scope_to_insns_initialize): Clear block when we
969 hit the FUNCTION_DECL.
970 * function.c: Do not create cyclic tree structure.

994 (c_print_identifier): Update to match changes to struct
996 (poplevel): Delete #if 0 block. Make externals invisible
997 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
998 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
999 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1000 (duplicate-decls): For real parm decl after a forward decl,
1001 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1002 foo(...) { } with only a warning. Say whether a previous
1003 declaration was implicit.
1004 (warn_if_shadowing): Now handles all shadowing, not just
1005 local-over-local. Clarify comments.
1006 (pushdecl): Rewritten. There is no longer a distinction
1007 between global and local symbol values; they're all
1008 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1009 DECL_EXTERNAL decls, and use any_external_decl to check
1010 against previous externals. Kill #if 0 blocks. Don't
1011 tolerate error_mark_node being NULL.

1013 Objective C (the only user) needs.
1014 (pushdecl_function_level): New function.
1015 (implicitly_declare): Create ordinary decls with

1027 (identifier_global_value): Same. Must scan
1028 global_binding_level in extremis.
1030 * c-typeck.c (undeclared_variable): New static function, split
1031 from build_external_ref.

1036 IDENTIFIER_GLOBAL_VALUE.
