9527 (make_binding_level): Use ggc_alloc_cleared or memset.
9528 (lookup_tag): Remove struct binding_level* parameter. All
9529 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
9530 current_binding_level->tags if asked for thislevel_only or if
9531 we might have to diagnose "struct foo; union foo;"
9532 (pushlevel): Ignore argument. Do not push another binding
9533 level on the transition from the parameters to the top level
9534 of the function body; just tweak the flags and proceed.

9536 a function body, separate the parameter list from the
9537 top-level local variables.
9538 (set_block): Do nothing.

9582 (c_print_identifier): Update to match changes to struct
9584 (poplevel): Delete #if 0 block. Make externals invisible
9585 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9586 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9587 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9588 (duplicate-decls): For real parm decl after a forward decl,
9589 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9590 foo(...) { } with only a warning. Say whether a previous
9591 declaration was implicit.
9592 (warn_if_shadowing): Now handles all shadowing, not just
9593 local-over-local. Clarify comments.
9594 (pushdecl): Rewritten. There is no longer a distinction
9595 between global and local symbol values; they're all
9596 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9597 DECL_EXTERNAL decls, and use any_external_decl to check
9598 against previous externals. Kill #if 0 blocks. Don't
9599 tolerate error_mark_node being NULL.

9601 Objective C (the only user) needs.
9602 (pushdecl_function_level): New function.
9603 (implicitly_declare): Create ordinary decls with
