13051 (make_binding_level): Use ggc_alloc_cleared or memset.
13052 (lookup_tag): Remove struct binding_level* parameter. All
13053 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
13054 current_binding_level->tags if asked for thislevel_only or if
13055 we might have to diagnose "struct foo; union foo;"
13056 (pushlevel): Ignore argument. Do not push another binding
13057 level on the transition from the parameters to the top level
13058 of the function body; just tweak the flags and proceed.

13060 a function body, separate the parameter list from the
13061 top-level local variables.

13074 empty functions. Otherwise, don't call poplevel.

13105 (clone_underlying type): Split out of pushdecl.
13106 (c_print_identifier): Update to match changes to struct
13108 (poplevel): Delete #if 0 block. Make externals invisible
13109 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13110 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13111 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13112 (duplicate-decls): For real parm decl after a forward decl,
13113 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
13114 foo(...) { } with only a warning. Say whether a previous

13117 local-over-local. Clarify comments.

13119 between global and local symbol values; they're all
13120 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13121 DECL_EXTERNAL decls, and use any_external_decl to check
13122 against previous externals. Kill #if 0 blocks. Don't
13123 tolerate error_mark_node being NULL.
13124 (pushdecl_top_level): Handle only those cases which
13125 Objective C (the only user) needs.
13126 (pushdecl_function_level): New function.

13143 from build_external_ref.

13148 IDENTIFIER_GLOBAL_VALUE.
