8516 (C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
8517 * c-common.h: Update prototypes.
8518 * c-decl.c (struct c_scope): Update commentary. Remove names,

8527 (poplevel): Rename to pop_scope; totally rewritten for new bindings
8529 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
8530 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
8531 Improve some commentary. Adjust handling of forward parm decls.
8532 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
8533 Preserve C_DECL_IN_EXTERNAL_SCOPE.
8534 (warn_if_shadowing): Correct indentation. Improve diagnostics.
8535 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
8536 decls. Rewrite for new bindings structures. Improve commentary.
8537 Eliminate the copy_node call.
8538 (implicit_decl_warning): Use the "diag" idiom (as seen in
8539 locate_old_decl) to reduce code duplication; call locate_old_decl
8540 if appropriate. Relocate to remove need for forward declaration.

8554 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
8555 First scope pushed is the external scope, not the global scope.

8561 (grokparms): Return 0 if arg_types is error_mark_node.
8562 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
8563 reversed sense. Rewrite for new bindings structures. Do not
8564 leave any decls in the scope, to prevent pop_scope from doing
8565 contradictory things with them.
8566 (finish_struct, finish_enum): Remove redundant diagnostics.
8567 (build_enumerator): Don't cascade diagnostics for error_mark_node.

8599 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
8600 correct loop over multiple translation units; call fatal_error if
8601 requested to compile more than one file at once. (This disables
8602 IMA temporarily - an up-front error being preferable to a crash.)
8603 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
8604 (all actions): Adjust calls to pushlevel/poplevel.
8605 (parsing_iso_function_signature): Delete.
8606 (extdef_1): Fold into extdef.

8614 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
8615 to suppress -Wold-style-definition after this error.
8616 (c_parse_file): Don't clear the binding stack or call
8617 finish_fname_decls here. Correct comment.
8618 * c-typeck.c (same_translation_unit_p): Export.

13387 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
13388 (_cpp_lex_direct): Use linemap_position_for_column.
13389 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
