7731 (make_binding_level): Use ggc_alloc_cleared or memset.
7732 (lookup_tag): Remove struct binding_level* parameter. All
7733 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
7734 current_binding_level->tags if asked for thislevel_only or if
7735 we might have to diagnose "struct foo; union foo;"
7736 (pushlevel): Ignore argument. Do not push another binding
7737 level on the transition from the parameters to the top level
7738 of the function body; just tweak the flags and proceed.
7739 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
7740 a function body, separate the parameter list from the
7741 top-level local variables.
7742 (set_block): Do nothing.

7744 shadowed_tags if necessary.

7754 empty functions. Otherwise, don't call poplevel.
7756 * c-common.c (shadow_warning): MANDATORY argument is no longer
7757 necessary. Always use plain warning.
7758 * c-common.h: Update to match.

7786 (c_print_identifier): Update to match changes to struct
7788 (poplevel): Delete #if 0 block. Make externals invisible
7789 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7790 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7791 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7792 (duplicate-decls): For real parm decl after a forward decl,
7793 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7794 foo(...) { } with only a warning. Say whether a previous
7795 declaration was implicit.
7796 (warn_if_shadowing): Now handles all shadowing, not just
7797 local-over-local. Clarify comments.
7798 (pushdecl): Rewritten. There is no longer a distinction
7799 between global and local symbol values; they're all
7800 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7801 DECL_EXTERNAL decls, and use any_external_decl to check
7802 against previous externals. Kill #if 0 blocks. Don't
7803 tolerate error_mark_node being NULL.

7805 Objective C (the only user) needs.
7806 (pushdecl_function_level): New function.
7807 (implicitly_declare): Create ordinary decls with

7828 IDENTIFIER_GLOBAL_VALUE.
