7271 (scope_freelist): Move to more appropriate location.
7272 (c_print_identifier): Update for changes to struct lang_identifier.
7273 (objc_mark_locals_volatile): Update for new bindings structures.
7274 (global_bindings_p): Honor c_override_global_bindings_to_false.
7275 (pushlevel): Rename to push_scope; take no arguments; use the
7276 scope_freelist; initialize scope->depth and check for overflow.
7277 (poplevel): Rename to pop_scope; totally rewritten for new bindings
7279 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
7280 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
7281 Improve some commentary. Adjust handling of forward parm decls.
7282 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
7283 Preserve C_DECL_IN_EXTERNAL_SCOPE.
7284 (warn_if_shadowing): Correct indentation. Improve diagnostics.
7285 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
7286 decls. Rewrite for new bindings structures. Improve commentary.
7287 Eliminate the copy_node call.
7288 (implicit_decl_warning): Use the "diag" idiom (as seen in
7289 locate_old_decl) to reduce code duplication; call locate_old_decl
7290 if appropriate. Relocate to remove need for forward declaration.
7291 (implicitly_declare): Adjust for new bindings structures. Kludge
7292 around Objective-C not-really-builtin functions.
7293 (undeclared_variable): Improve diagnostics. If current_function_decl

7301 second argument indicating the scope to examine; rewrite for

7303 (c_init_decl_processing): Adjust for renamed functions. Do not
7304 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
7305 First scope pushed is the external scope, not the global scope.

7309 (start_decl): Adjust diagnostics. Remove unnecessary call to
7311 (grokparms): Return 0 if arg_types is error_mark_node.
7312 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
7313 reversed sense. Rewrite for new bindings structures. Do not
7314 leave any decls in the scope, to prevent pop_scope from doing
7315 contradictory things with them.
7316 (finish_struct, finish_enum): Remove redundant diagnostics.
7317 (build_enumerator): Don't cascade diagnostics for error_mark_node.
7318 Mark location where -pedantic changes the meaning of the program.

7320 parameter decls into the function's scope structure using bind.

7349 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
7350 correct loop over multiple translation units; call fatal_error if
7351 requested to compile more than one file at once. (This disables
7352 IMA temporarily - an up-front error being preferable to a crash.)
7353 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
7354 (all actions): Adjust calls to pushlevel/poplevel.
7355 (parsing_iso_function_signature): Delete.

7361 commented-out productions.

7363 an empty TREE_LIST node. Adjust calls to get_parm_info.
7364 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
7365 to suppress -Wold-style-definition after this error.
7366 (c_parse_file): Don't clear the binding stack or call
7367 finish_fname_decls here. Correct comment.
7368 * c-typeck.c (same_translation_unit_p): Export.

12138 (_cpp_lex_direct): Use linemap_position_for_column.
12139 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
