structures.

decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.

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

made visible automatically.

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.

Mark location where -pedantic changes the meaning of the program.

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.

(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.

(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.

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.
