+ * cpperror.c (cpp_file_line_for_message): If 'line' is zero,
+ just print "<command line>". If 'filename' is null or an
+ empty string, print "<stdin>" for the filename.
+ * cpplib.c (do_define): Don't print the 'location of the
+ previous definition' message if we're still parsing the
+ command line.
+ (cpp_pedwarn_with_file_and_line): Always call
+ cpp_file_line_for_message.
