9352 (objc_mark_locals_volatile): Update for new bindings structures.
9353 (global_bindings_p): Honor c_override_global_bindings_to_false.
9354 (pushlevel): Rename to push_scope; take no arguments; use the
9355 scope_freelist; initialize scope->depth and check for overflow.
9356 (poplevel): Rename to pop_scope; totally rewritten for new bindings
9358 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
9359 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
9360 Improve some commentary. Adjust handling of forward parm decls.
9361 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
9362 Preserve C_DECL_IN_EXTERNAL_SCOPE.
9363 (warn_if_shadowing): Correct indentation. Improve diagnostics.
9364 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
9365 decls. Rewrite for new bindings structures. Improve commentary.
9366 Eliminate the copy_node call.
9367 (implicit_decl_warning): Use the "diag" idiom (as seen in
9368 locate_old_decl) to reduce code duplication; call locate_old_decl

9383 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
9384 First scope pushed is the external scope, not the global scope.

9388 (start_decl): Adjust diagnostics. Remove unnecessary call to
9390 (grokparms): Return 0 if arg_types is error_mark_node.
9391 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
9392 reversed sense. Rewrite for new bindings structures. Do not
9393 leave any decls in the scope, to prevent pop_scope from doing
9394 contradictory things with them.
9395 (finish_struct, finish_enum): Remove redundant diagnostics.

9428 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
9429 correct loop over multiple translation units; call fatal_error if
9430 requested to compile more than one file at once. (This disables
9431 IMA temporarily - an up-front error being preferable to a crash.)
