9015 (make_binding_level): Use ggc_alloc_cleared or memset.
9016 (lookup_tag): Remove struct binding_level* parameter. All
9017 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
9018 current_binding_level->tags if asked for thislevel_only or if
9019 we might have to diagnose "struct foo; union foo;"
9020 (pushlevel): Ignore argument. Do not push another binding
9021 level on the transition from the parameters to the top level
9022 of the function body; just tweak the flags and proceed.
9023 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
9024 a function body, separate the parameter list from the
9025 top-level local variables.
9026 (set_block): Do nothing.

9028 shadowed_tags if necessary.

9038 empty functions. Otherwise, don't call poplevel.

9070 (c_print_identifier): Update to match changes to struct
9072 (poplevel): Delete #if 0 block. Make externals invisible
9073 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9074 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9075 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9076 (duplicate-decls): For real parm decl after a forward decl,
9077 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9078 foo(...) { } with only a warning. Say whether a previous
9079 declaration was implicit.
9080 (warn_if_shadowing): Now handles all shadowing, not just
9081 local-over-local. Clarify comments.
9082 (pushdecl): Rewritten. There is no longer a distinction
9083 between global and local symbol values; they're all
9084 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9085 DECL_EXTERNAL decls, and use any_external_decl to check
9086 against previous externals. Kill #if 0 blocks. Don't
9087 tolerate error_mark_node being NULL.

9089 Objective C (the only user) needs.
9090 (pushdecl_function_level): New function.
9091 (implicitly_declare): Create ordinary decls with
