8085 * c-common.h: Update prototypes.
8086 * c-decl.c (struct c_scope): Update commentary. Remove names,

8095 (poplevel): Rename to pop_scope; totally rewritten for new bindings
8097 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
8098 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
8099 Improve some commentary. Adjust handling of forward parm decls.
8100 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
8101 Preserve C_DECL_IN_EXTERNAL_SCOPE.
8102 (warn_if_shadowing): Correct indentation. Improve diagnostics.
8103 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
8104 decls. Rewrite for new bindings structures. Improve commentary.
8105 Eliminate the copy_node call.
8106 (implicit_decl_warning): Use the "diag" idiom (as seen in
8107 locate_old_decl) to reduce code duplication; call locate_old_decl
8108 if appropriate. Relocate to remove need for forward declaration.

8129 (grokparms): Return 0 if arg_types is error_mark_node.
8130 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
8131 reversed sense. Rewrite for new bindings structures. Do not
8132 leave any decls in the scope, to prevent pop_scope from doing
8133 contradictory things with them.
8134 (finish_struct, finish_enum): Remove redundant diagnostics.
8135 (build_enumerator): Don't cascade diagnostics for error_mark_node.

8167 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
8168 correct loop over multiple translation units; call fatal_error if
8169 requested to compile more than one file at once. (This disables
8170 IMA temporarily - an up-front error being preferable to a crash.)
8171 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
8172 (all actions): Adjust calls to pushlevel/poplevel.
8173 (parsing_iso_function_signature): Delete.
8174 (extdef_1): Fold into extdef.

8182 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
8183 to suppress -Wold-style-definition after this error.
8184 (c_parse_file): Don't clear the binding stack or call
8185 finish_fname_decls here. Correct comment.
8186 * c-typeck.c (same_translation_unit_p): Export.

12955 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
12956 (_cpp_lex_direct): Use linemap_position_for_column.
12957 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
12958 parameter. Instead get it from the line_table global. Adjust callers.
