(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.

(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.
