Update.

2004-03-08  Paul Eggert  <eggert@cs.ucla.edu>

	Merge from gnulib.  We now assume C89 or better.
	* posix/getopt1.c (const): Remove.
	* posix/getopt.c (const): Likewise.
	* posix/getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,
	_getopt_long_only_r, main): Use prototypes, not old-style definitions.
	* posix/getopt.c (exchange, _getopt_initialize, _getopt_internal_r,
	_getopt_internal, getopt, main): Likewise.
	* posix/getopt.h (getopt, getopt_long, getopt_long_only): Likewise.
	* posix/getopt.c [!defined VMS || !HAVE_STRING_H]:
	Include <string.h> regardless.  No need for <strings.h>.
	[!defined _LIBC]: Include "gettext.h" rather than rolling it ourselves.
	(_): Define to gettext always.
	(my_index): Remove: all uses changed to strchr.
	(strlen): Remove declaration.
	* posix/getopt.h (struct option.name): Always const char *.

2004-03-08  Marcus Brinkmann  <marcus@gnu.org>

	* posix/getopt.h (_getopt_internal): Move to ...
	* posix/getopt_int.h: ... here.  New file.
	* include/getopt_int.h: New file.
	* include/getopt.h: Remove libc_hidden_proto for getopt_long
	and getopt_long_only.
	* posix/getopt1.c: Include "getopt_int.h".  Remove
	libc_hidden_def for getopt_long and getopt_long_only.
	(_getopt_long_r, _getopt_long_only_r): New functions.
	* posix/getopt.c: Include "getopt_int.h".
	(__getopt_initialized): Variable removed.
	(nextchar, ordering, posixly_correct, first_nonopt, last_nonopt):
	Static variables removed.
	(nonoption_flags_max_len, nonoption_flags_len) [_LIBC &&
	USE_NONOPTION_FLAGS]: Static variables removed.
	(getopt_data): New static variable.
	(SWAP_FLAGS): Use d->__nonoption_flags_len instead
	nonoption_flags_len.
	(exchange): Add new argument D of type struct getopt_data *.
	Replace optind with d->optind, optarg with d->optarg, opterr with
	d->opterr, optopt with d->optopt, nextchar with d->__nextchar,
	first_nonopt with d->__first_nonopt, last_nonopt with
	d->__last_nonopt, d->ordering with d->__ordering,
	d->posixly_correct with d->__posixly_correct (which is now an
	int instead a string, so fix users), nonoption_flags_len
	with d->__nonoption_flags_len, nonoption_flags_max_len with
	d->__nonoption_flags_max_len.
	(_getopt_initialize): Likewise.
	(_getopt_internal): Rename to ...
	(_getopt_internal_r): ... this.  Also add new argument D of type
	struct getopt_data * and use of members of D rather than global or
	static variables as described for exchange() above.  Add new argument
	to invocations of _getopt_initialize and exchange.
	(_getopt_internal): Reimplement in terms of _getopt_internal_r.
	* argp/argp-parse.c: Include <getopt_int.h>.
	[_LIBC]: Do not include <bits/libc-lock.h>.
	[!_LIBC && HAVE_CTHREADS_H]: Do not include <cthreads.h>.
	[!_LIBC] (_argp_hang): Make static.
	(getopt_lock, LOCK_GETOPT, UNLOCK_GETOPT): Remove.
	(_argp_unlock_xxx): Remove.
	(parser_init): Do not use LOCK_GETOPT.
	(parser_finalize): Do not use UNLOCK_GETOPT.
	(struct parser): New member OPT_DATA.
	(parser_init): Initialize parser->opt_data.  Use
	parser->opt_data.opterr instead of opterr.
	(parser_parse_opt): Use parser->opt_data.optarg instead optarg.
	(parser_parse_next): Likewise.  Use parser->opt_data.optind
	instead optind.  Use parser->opt_data.optopt instead of optopt.
	Call _getopt_long_only_r and _getopt_long_r instead of
	getopt_long_only and getopt_long, and pass the extra argument.

+     If the caller did not specify anything,

+     POSIXLY_CORRECT is defined, PERMUTE otherwise.
+
+     REQUIRE_ORDER means don't recognize them as options;
+     stop option processing when the first non-option is seen.
+     This is what Unix does.
+     This mode of operation is selected by either setting the environment
+     variable POSIXLY_CORRECT, or using `+' as the first character
+     of the list of option characters.
+
+     PERMUTE is the default.  We permute the contents of ARGV as we
+     scan, so that eventually all the non-options are at the end.
+     This allows options to be given in any order, even with programs
+     that were not written to expect this.
+
+     RETURN_IN_ORDER is an option available to programs that were
+     written to expect options and other ARGV-elements in any order
+     and that care about the ordering of the two.  We describe each
+     non-option ARGV-element as if it were the argument of an option
+     with character code 1.  Using `-' as the first character of the
+     list of option characters selects this mode of operation.
+
+     The special argument `--' forces an end of option-scanning regardless
+     of the value of `ordering'.  In the case of RETURN_IN_ORDER, only
+     `--' can cause `getopt' to return -1 with `optind' != ARGC.  */
