3654 (make_binding_level): Use ggc_alloc_cleared or memset.
3655 (lookup_tag): Remove struct binding_level* parameter. All
3656 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
3657 current_binding_level->tags if asked for thislevel_only or if
3658 we might have to diagnose "struct foo; union foo;"
3659 (pushlevel): Ignore argument. Do not push another binding
3660 level on the transition from the parameters to the top level
3661 of the function body; just tweak the flags and proceed.
3662 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
3663 a function body, separate the parameter list from the
3664 top-level local variables.
3665 (set_block): Do nothing.
3666 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
3667 shadowed_tags if necessary.

3674 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
3675 (start_function): Don't set subblocks_tag_transparent.
3676 (finish_function): Fix up the binding_level stack for totally
3677 empty functions. Otherwise, don't call poplevel.
3679 * c-common.c (shadow_warning): MANDATORY argument is no longer
3680 necessary. Always use plain warning.
3681 * c-common.h: Update to match.

3684 hit the FUNCTION_DECL.
3685 * function.c: Do not create cyclic tree structure.

3709 (c_print_identifier): Update to match changes to struct
3711 (poplevel): Delete #if 0 block. Make externals invisible
3712 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
3713 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
3714 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
3715 (duplicate-decls): For real parm decl after a forward decl,
3716 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
3717 foo(...) { } with only a warning. Say whether a previous
3718 declaration was implicit.
3719 (warn_if_shadowing): Now handles all shadowing, not just
3720 local-over-local. Clarify comments.
3721 (pushdecl): Rewritten. There is no longer a distinction
3722 between global and local symbol values; they're all
3723 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
3724 DECL_EXTERNAL decls, and use any_external_decl to check
3725 against previous externals. Kill #if 0 blocks. Don't
3726 tolerate error_mark_node being NULL.

3728 Objective C (the only user) needs.
3729 (pushdecl_function_level): New function.
3730 (implicitly_declare): Create ordinary decls with

3746 from build_external_ref.
