4957 (make_binding_level): Use ggc_alloc_cleared or memset.
4958 (lookup_tag): Remove struct binding_level* parameter. All
4959 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
4960 current_binding_level->tags if asked for thislevel_only or if
4961 we might have to diagnose "struct foo; union foo;"
4962 (pushlevel): Ignore argument. Do not push another binding
4963 level on the transition from the parameters to the top level
4964 of the function body; just tweak the flags and proceed.
4965 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
4966 a function body, separate the parameter list from the
4967 top-level local variables.
4968 (set_block): Do nothing.

4970 shadowed_tags if necessary.

4977 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
4978 (start_function): Don't set subblocks_tag_transparent.
4979 (finish_function): Fix up the binding_level stack for totally
4980 empty functions. Otherwise, don't call poplevel.
4982 * c-common.c (shadow_warning): MANDATORY argument is no longer
4983 necessary. Always use plain warning.
4984 * c-common.h: Update to match.

4987 hit the FUNCTION_DECL.

5012 (c_print_identifier): Update to match changes to struct
5014 (poplevel): Delete #if 0 block. Make externals invisible
5015 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5016 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5017 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5018 (duplicate-decls): For real parm decl after a forward decl,
5019 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
5020 foo(...) { } with only a warning. Say whether a previous
5021 declaration was implicit.
5022 (warn_if_shadowing): Now handles all shadowing, not just
5023 local-over-local. Clarify comments.
5024 (pushdecl): Rewritten. There is no longer a distinction
5025 between global and local symbol values; they're all
5026 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
5027 DECL_EXTERNAL decls, and use any_external_decl to check
5028 against previous externals. Kill #if 0 blocks. Don't
5029 tolerate error_mark_node being NULL.

5031 Objective C (the only user) needs.
5032 (pushdecl_function_level): New function.
5033 (implicitly_declare): Create ordinary decls with

5049 from build_external_ref.

5054 IDENTIFIER_GLOBAL_VALUE.
