12603 (make_binding_level): Use ggc_alloc_cleared or memset.
12604 (lookup_tag): Remove struct binding_level* parameter. All
12605 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
12606 current_binding_level->tags if asked for thislevel_only or if
12607 we might have to diagnose "struct foo; union foo;"
12608 (pushlevel): Ignore argument. Do not push another binding
12609 level on the transition from the parameters to the top level
12610 of the function body; just tweak the flags and proceed.

12612 a function body, separate the parameter list from the
12613 top-level local variables.

12616 shadowed_tags if necessary.

12623 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
12624 (start_function): Don't set subblocks_tag_transparent.
12625 (finish_function): Fix up the binding_level stack for totally
12626 empty functions. Otherwise, don't call poplevel.

12629 necessary. Always use plain warning.
12630 * c-common.h: Update to match.

12658 (c_print_identifier): Update to match changes to struct
12660 (poplevel): Delete #if 0 block. Make externals invisible
12661 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12662 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12663 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12664 (duplicate-decls): For real parm decl after a forward decl,
12665 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
12666 foo(...) { } with only a warning. Say whether a previous

12668 (warn_if_shadowing): Now handles all shadowing, not just
12669 local-over-local. Clarify comments.
12670 (pushdecl): Rewritten. There is no longer a distinction
12671 between global and local symbol values; they're all
12672 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12673 DECL_EXTERNAL decls, and use any_external_decl to check
12674 against previous externals. Kill #if 0 blocks. Don't
12675 tolerate error_mark_node being NULL.
12676 (pushdecl_top_level): Handle only those cases which
12677 Objective C (the only user) needs.
12678 (pushdecl_function_level): New function.
12679 (implicitly_declare): Create ordinary decls with

12695 from build_external_ref.

12700 IDENTIFIER_GLOBAL_VALUE.
