Update.

	    Andreas Schwab  <schwab@suse.de>
	    Bruno Haible  <haible@clisp.cons.org>

	* locale/programs/3level.h (EMPTY): New macro.
	(*_get, *_add, *_iterate, *_finalize): Use it instead of ~(uint32_t) 0.

2001-08-08  GOTO Masanori  <gotom@debian.or.jp>

	* locale/iso-3166.def: Updates from latest official list.

2001-08-07  Andreas Jaeger  <aj@suse.de>
	* iconv/gconv_charset.h (upstr): Add unused attribute to avoid warning.
	* libio/iopopen.c (_IO_new_proc_open): Fix typos, it's _IO_MTSAFE_IO.
