5445 (make_binding_level): Use ggc_alloc_cleared or memset.
5446 (lookup_tag): Remove struct binding_level* parameter. All
5447 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
5448 current_binding_level->tags if asked for thislevel_only or if
5449 we might have to diagnose "struct foo; union foo;"
5450 (pushlevel): Ignore argument. Do not push another binding
5451 level on the transition from the parameters to the top level
5452 of the function body; just tweak the flags and proceed.

5454 a function body, separate the parameter list from the
5455 top-level local variables.

5468 empty functions. Otherwise, don't call poplevel.

5500 (c_print_identifier): Update to match changes to struct
5502 (poplevel): Delete #if 0 block. Make externals invisible
5503 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5504 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5505 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5506 (duplicate-decls): For real parm decl after a forward decl,
5507 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
5508 foo(...) { } with only a warning. Say whether a previous
5509 declaration was implicit.
5510 (warn_if_shadowing): Now handles all shadowing, not just
5511 local-over-local. Clarify comments.
5512 (pushdecl): Rewritten. There is no longer a distinction
5513 between global and local symbol values; they're all
5514 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
5515 DECL_EXTERNAL decls, and use any_external_decl to check
5516 against previous externals. Kill #if 0 blocks. Don't
5517 tolerate error_mark_node being NULL.

5519 Objective C (the only user) needs.
5520 (pushdecl_function_level): New function.
5521 (implicitly_declare): Create ordinary decls with
