10902 (make_binding_level): Use ggc_alloc_cleared or memset.
10903 (lookup_tag): Remove struct binding_level* parameter. All
10904 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
10905 current_binding_level->tags if asked for thislevel_only or if
10906 we might have to diagnose "struct foo; union foo;"
10907 (pushlevel): Ignore argument. Do not push another binding
10908 level on the transition from the parameters to the top level
10909 of the function body; just tweak the flags and proceed.

10911 a function body, separate the parameter list from the
10912 top-level local variables.

10957 (c_print_identifier): Update to match changes to struct
10959 (poplevel): Delete #if 0 block. Make externals invisible
10960 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10961 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10962 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10963 (duplicate-decls): For real parm decl after a forward decl,
10964 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10965 foo(...) { } with only a warning. Say whether a previous

10968 local-over-local. Clarify comments.

10970 between global and local symbol values; they're all
10971 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10972 DECL_EXTERNAL decls, and use any_external_decl to check
10973 against previous externals. Kill #if 0 blocks. Don't
10974 tolerate error_mark_node being NULL.
10975 (pushdecl_top_level): Handle only those cases which
10976 Objective C (the only user) needs.
10977 (pushdecl_function_level): New function.
