* dlltool.c (usage): Add file parameter. Change all callers.

(main): Don't treat '?' as a special case in getopt return.

	* binutils.texi (dlltool): Document new options.  Add some uses of
	@var.

	* dlltool.c (gen_def_file): Plug memory leak.  Don't print
	demangled name if it is NULL.

	Support for exporting all symbols to an output export def file:
	* dlltool.c ({export_all_symbols, no_default_excludes,
	no_default_excludes, excludes}): New file static variables.
	(struct string_list): Type to hold list of symbols to exclude.
	(scan_drectve_symbols): Renamed from scan_open_obj_file.
	(scan_filtered_symbols): New static function.
	(add_excludes): New static function.
	(match_exclude): New static function.
	(set_default_excludes): New static function.
	(filter_symbols): New static function.
	(scan_all_symbols): New static function.
	(scan_open_obj_file): New static function.
	(usage): Document new options.
	(long_options): Add new options.
	(main): Handle new options.
