12599 (make_binding_level): Use ggc_alloc_cleared or memset.
12600 (lookup_tag): Remove struct binding_level* parameter. All
12601 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
12602 current_binding_level->tags if asked for thislevel_only or if
12603 we might have to diagnose "struct foo; union foo;"
12604 (pushlevel): Ignore argument. Do not push another binding
12605 level on the transition from the parameters to the top level
12606 of the function body; just tweak the flags and proceed.

12608 a function body, separate the parameter list from the
12609 top-level local variables.

12612 shadowed_tags if necessary.

12619 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
12620 (start_function): Don't set subblocks_tag_transparent.

12622 empty functions. Otherwise, don't call poplevel.

12625 necessary. Always use plain warning.
12626 * c-common.h: Update to match.

12654 (c_print_identifier): Update to match changes to struct
12656 (poplevel): Delete #if 0 block. Make externals invisible
12657 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12658 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12659 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12660 (duplicate-decls): For real parm decl after a forward decl,
12661 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
12662 foo(...) { } with only a warning. Say whether a previous

12664 (warn_if_shadowing): Now handles all shadowing, not just
12665 local-over-local. Clarify comments.
12666 (pushdecl): Rewritten. There is no longer a distinction
12667 between global and local symbol values; they're all
12668 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12669 DECL_EXTERNAL decls, and use any_external_decl to check
12670 against previous externals. Kill #if 0 blocks. Don't
12671 tolerate error_mark_node being NULL.
12672 (pushdecl_top_level): Handle only those cases which
12673 Objective C (the only user) needs.
12674 (pushdecl_function_level): New function.

12691 from build_external_ref.

12696 IDENTIFIER_GLOBAL_VALUE.
