7682 (make_binding_level): Use ggc_alloc_cleared or memset.
7683 (lookup_tag): Remove struct binding_level* parameter. All
7684 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
7685 current_binding_level->tags if asked for thislevel_only or if
7686 we might have to diagnose "struct foo; union foo;"
7687 (pushlevel): Ignore argument. Do not push another binding
7688 level on the transition from the parameters to the top level
7689 of the function body; just tweak the flags and proceed.
7690 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
7691 a function body, separate the parameter list from the
7692 top-level local variables.
7693 (set_block): Do nothing.
7694 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
7695 shadowed_tags if necessary.

7699 an older decl in the same binding level.
7700 (pushdecl_function_level): Tweak for new way of indicating
7702 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
7703 (start_function): Don't set subblocks_tag_transparent.
7704 (finish_function): Fix up the binding_level stack for totally
7705 empty functions. Otherwise, don't call poplevel.
7707 * c-common.c (shadow_warning): MANDATORY argument is no longer
7708 necessary. Always use plain warning.
7709 * c-common.h: Update to match.

7712 hit the FUNCTION_DECL.
7713 * function.c: Do not create cyclic tree structure.

7737 (c_print_identifier): Update to match changes to struct
7739 (poplevel): Delete #if 0 block. Make externals invisible
7740 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7741 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7742 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7743 (duplicate-decls): For real parm decl after a forward decl,
7744 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7745 foo(...) { } with only a warning. Say whether a previous
7746 declaration was implicit.
7747 (warn_if_shadowing): Now handles all shadowing, not just
7748 local-over-local. Clarify comments.
7749 (pushdecl): Rewritten. There is no longer a distinction
7750 between global and local symbol values; they're all
7751 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7752 DECL_EXTERNAL decls, and use any_external_decl to check
7753 against previous externals. Kill #if 0 blocks. Don't
7754 tolerate error_mark_node being NULL.

7756 Objective C (the only user) needs.
7757 (pushdecl_function_level): New function.
7758 (implicitly_declare): Create ordinary decls with
