7772 (make_binding_level): Use ggc_alloc_cleared or memset.
7773 (lookup_tag): Remove struct binding_level* parameter. All
7774 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
7775 current_binding_level->tags if asked for thislevel_only or if
7776 we might have to diagnose "struct foo; union foo;"
7777 (pushlevel): Ignore argument. Do not push another binding
7778 level on the transition from the parameters to the top level
7779 of the function body; just tweak the flags and proceed.

7781 a function body, separate the parameter list from the
7782 top-level local variables.
7783 (set_block): Do nothing.

7785 shadowed_tags if necessary.

7795 empty functions. Otherwise, don't call poplevel.
7797 * c-common.c (shadow_warning): MANDATORY argument is no longer
7798 necessary. Always use plain warning.

7827 (c_print_identifier): Update to match changes to struct
7829 (poplevel): Delete #if 0 block. Make externals invisible
7830 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
7831 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
7832 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
7833 (duplicate-decls): For real parm decl after a forward decl,
7834 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
7835 foo(...) { } with only a warning. Say whether a previous
7836 declaration was implicit.
7837 (warn_if_shadowing): Now handles all shadowing, not just
7838 local-over-local. Clarify comments.
7839 (pushdecl): Rewritten. There is no longer a distinction
7840 between global and local symbol values; they're all
7841 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
7842 DECL_EXTERNAL decls, and use any_external_decl to check
7843 against previous externals. Kill #if 0 blocks. Don't
7844 tolerate error_mark_node being NULL.

7846 Objective C (the only user) needs.
7847 (pushdecl_function_level): New function.
7848 (implicitly_declare): Create ordinary decls with
