7767 (make_binding_level): Use ggc_alloc_cleared or memset.
7768 (lookup_tag): Remove struct binding_level* parameter. All
7769 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
7770 current_binding_level->tags if asked for thislevel_only or if
7771 we might have to diagnose "struct foo; union foo;"
7772 (pushlevel): Ignore argument. Do not push another binding
7773 level on the transition from the parameters to the top level
7774 of the function body; just tweak the flags and proceed.
7775 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
7776 a function body, separate the parameter list from the
7777 top-level local variables.
7778 (set_block): Do nothing.

7780 shadowed_tags if necessary.

7787 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
7788 (start_function): Don't set subblocks_tag_transparent.

7790 empty functions. Otherwise, don't call poplevel.
7792 * c-common.c (shadow_warning): MANDATORY argument is no longer
7793 necessary. Always use plain warning.
7794 * c-common.h: Update to match.

7822 (c_print_identifier): Update to match changes to struct
7824 (poplevel): Delete #if 0 block. Make externals invisible
7825 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7826 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7827 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7828 (duplicate-decls): For real parm decl after a forward decl,
7829 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7830 foo(...) { } with only a warning. Say whether a previous
7831 declaration was implicit.
7832 (warn_if_shadowing): Now handles all shadowing, not just
7833 local-over-local. Clarify comments.
7834 (pushdecl): Rewritten. There is no longer a distinction
7835 between global and local symbol values; they're all
7836 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7837 DECL_EXTERNAL decls, and use any_external_decl to check
7838 against previous externals. Kill #if 0 blocks. Don't
7839 tolerate error_mark_node being NULL.

7841 Objective C (the only user) needs.
7842 (pushdecl_function_level): New function.
7843 (implicitly_declare): Create ordinary decls with

7859 from build_external_ref.

7864 IDENTIFIER_GLOBAL_VALUE.
