10014 (make_binding_level): Use ggc_alloc_cleared or memset.
10015 (lookup_tag): Remove struct binding_level* parameter. All
10016 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
10017 current_binding_level->tags if asked for thislevel_only or if
10018 we might have to diagnose "struct foo; union foo;"
10019 (pushlevel): Ignore argument. Do not push another binding
10020 level on the transition from the parameters to the top level
10021 of the function body; just tweak the flags and proceed.

10023 a function body, separate the parameter list from the
10024 top-level local variables.

10069 (c_print_identifier): Update to match changes to struct
10071 (poplevel): Delete #if 0 block. Make externals invisible
10072 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10073 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10074 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10075 (duplicate-decls): For real parm decl after a forward decl,
10076 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10077 foo(...) { } with only a warning. Say whether a previous

10080 local-over-local. Clarify comments.

10083 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10084 DECL_EXTERNAL decls, and use any_external_decl to check
10085 against previous externals. Kill #if 0 blocks. Don't
10086 tolerate error_mark_node being NULL.
10087 (pushdecl_top_level): Handle only those cases which
10088 Objective C (the only user) needs.
10089 (pushdecl_function_level): New function.
