9817 (make_binding_level): Use ggc_alloc_cleared or memset.
9818 (lookup_tag): Remove struct binding_level* parameter. All

9820 current_binding_level->tags if asked for thislevel_only or if
9821 we might have to diagnose "struct foo; union foo;"
9822 (pushlevel): Ignore argument. Do not push another binding
9823 level on the transition from the parameters to the top level
9824 of the function body; just tweak the flags and proceed.

9826 a function body, separate the parameter list from the
9827 top-level local variables.

9830 shadowed_tags if necessary.

9840 empty functions. Otherwise, don't call poplevel.

9872 (c_print_identifier): Update to match changes to struct
9874 (poplevel): Delete #if 0 block. Make externals invisible
9875 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9876 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9877 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9878 (duplicate-decls): For real parm decl after a forward decl,
9879 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9880 foo(...) { } with only a warning. Say whether a previous
9881 declaration was implicit.
9882 (warn_if_shadowing): Now handles all shadowing, not just
9883 local-over-local. Clarify comments.
9884 (pushdecl): Rewritten. There is no longer a distinction
9885 between global and local symbol values; they're all
9886 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9887 DECL_EXTERNAL decls, and use any_external_decl to check
9888 against previous externals. Kill #if 0 blocks. Don't
9889 tolerate error_mark_node being NULL.
9890 (pushdecl_top_level): Handle only those cases which
9891 Objective C (the only user) needs.
9892 (pushdecl_function_level): New function.
9893 (implicitly_declare): Create ordinary decls with
9894 C_DECL_IMPLICIT set. Recycle old decls, however they got
9896 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
9897 for C_DECL_INVISIBLE symbols.
9898 (lookup_name_current_level): Likewise. Use chain_member.

9903 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
9904 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
9905 (identifier_global_value): Same. Must scan
9906 global_binding_level in extremis.
9908 * c-typeck.c (undeclared_variable): New static function, split
9909 from build_external_ref.
9910 (build_external_ref): Use DECL_CONTEXT, not
