12631 (make_binding_level): Use ggc_alloc_cleared or memset.
12632 (lookup_tag): Remove struct binding_level* parameter. All
12633 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
12634 current_binding_level->tags if asked for thislevel_only or if
12635 we might have to diagnose "struct foo; union foo;"
12636 (pushlevel): Ignore argument. Do not push another binding
12637 level on the transition from the parameters to the top level
12638 of the function body; just tweak the flags and proceed.

12640 a function body, separate the parameter list from the
12641 top-level local variables.

12686 (c_print_identifier): Update to match changes to struct
12688 (poplevel): Delete #if 0 block. Make externals invisible
12689 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12690 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12691 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12692 (duplicate-decls): For real parm decl after a forward decl,
12693 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
12694 foo(...) { } with only a warning. Say whether a previous

12697 local-over-local. Clarify comments.

12699 between global and local symbol values; they're all
12700 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12701 DECL_EXTERNAL decls, and use any_external_decl to check
12702 against previous externals. Kill #if 0 blocks. Don't
12703 tolerate error_mark_node being NULL.
12704 (pushdecl_top_level): Handle only those cases which
12705 Objective C (the only user) needs.
12706 (pushdecl_function_level): New function.
