6768 (make_binding_level): Use ggc_alloc_cleared or memset.
6769 (lookup_tag): Remove struct binding_level* parameter. All
6770 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
6771 current_binding_level->tags if asked for thislevel_only or if
6772 we might have to diagnose "struct foo; union foo;"
6773 (pushlevel): Ignore argument. Do not push another binding
6774 level on the transition from the parameters to the top level
6775 of the function body; just tweak the flags and proceed.
6776 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
6777 a function body, separate the parameter list from the
6778 top-level local variables.
6779 (set_block): Do nothing.
6780 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
6781 shadowed_tags if necessary.

6788 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
6789 (start_function): Don't set subblocks_tag_transparent.
6790 (finish_function): Fix up the binding_level stack for totally
6791 empty functions. Otherwise, don't call poplevel.
6793 * c-common.c (shadow_warning): MANDATORY argument is no longer
6794 necessary. Always use plain warning.
6795 * c-common.h: Update to match.

6798 hit the FUNCTION_DECL.
6799 * function.c: Do not create cyclic tree structure.

6823 (c_print_identifier): Update to match changes to struct
6825 (poplevel): Delete #if 0 block. Make externals invisible
6826 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6827 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6828 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6829 (duplicate-decls): For real parm decl after a forward decl,
6830 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
6831 foo(...) { } with only a warning. Say whether a previous
6832 declaration was implicit.
6833 (warn_if_shadowing): Now handles all shadowing, not just
6834 local-over-local. Clarify comments.
6835 (pushdecl): Rewritten. There is no longer a distinction
6836 between global and local symbol values; they're all
6837 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6838 DECL_EXTERNAL decls, and use any_external_decl to check
6839 against previous externals. Kill #if 0 blocks. Don't
6840 tolerate error_mark_node being NULL.

6842 Objective C (the only user) needs.
6843 (pushdecl_function_level): New function.
6844 (implicitly_declare): Create ordinary decls with
