11800 (make_binding_level): Use ggc_alloc_cleared or memset.
11801 (lookup_tag): Remove struct binding_level* parameter. All
11802 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
11803 current_binding_level->tags if asked for thislevel_only or if
11804 we might have to diagnose "struct foo; union foo;"
11805 (pushlevel): Ignore argument. Do not push another binding
11806 level on the transition from the parameters to the top level
11807 of the function body; just tweak the flags and proceed.

11809 a function body, separate the parameter list from the
11810 top-level local variables.

11813 shadowed_tags if necessary.

11820 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
11821 (start_function): Don't set subblocks_tag_transparent.

11823 empty functions. Otherwise, don't call poplevel.

11826 necessary. Always use plain warning.
11827 * c-common.h: Update to match.

11854 (clone_underlying type): Split out of pushdecl.
11855 (c_print_identifier): Update to match changes to struct
11857 (poplevel): Delete #if 0 block. Make externals invisible
11858 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
11859 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
11860 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
11861 (duplicate-decls): For real parm decl after a forward decl,
11862 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
11863 foo(...) { } with only a warning. Say whether a previous

11865 (warn_if_shadowing): Now handles all shadowing, not just
11866 local-over-local. Clarify comments.
11867 (pushdecl): Rewritten. There is no longer a distinction
11868 between global and local symbol values; they're all
11869 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
11870 DECL_EXTERNAL decls, and use any_external_decl to check
11871 against previous externals. Kill #if 0 blocks. Don't
11872 tolerate error_mark_node being NULL.
11873 (pushdecl_top_level): Handle only those cases which
11874 Objective C (the only user) needs.
11875 (pushdecl_function_level): New function.

11892 from build_external_ref.

11897 IDENTIFIER_GLOBAL_VALUE.
