Update.

	* string/endian.h: Explain the _*_ENDIAN constant values a bit
	more.  Patch by scarlet@mit.edu [PR libc/1799].

	* io/ftwtest-sh: Add -f parameter to chmod if -R is also given.
	[PR libc/1792].

	* argp/argp-parse.c (parser_finalize): Reverse order in which
	parsers are run for ARGP_KEY_END.  [PR libc/1755].

-The GNU C library now includes Michael Glad's Ultra Fast Crypt, which
-provides the Unix `crypt' function, plus some other entry points.
-Because of the United States export restriction on DES
-implementations, we are distributing this code separately from the
-rest of the C library.  There is an extra distribution tar file just
-for crypt; it is called `glibc-crypt-2.1.91.tar.gz'.  You can just
-unpack the crypt distribution along with the rest of the C library and
-build; you can also build the library without getting crypt.  Users
-outside the USA can get the crypt distribution via anonymous FTP from
-ftp.gwdg.de [134.76.11.100] in the directory pub/linux/glibc, or
-another archive site outside the USA.  Archive maintainers are
-encouraged to copy this distribution to their archives outside the
-USA.  Please get it from ftp.gwdg.de; transferring this distribution
-from ftp.gnu.org (or any other site in the USA) to a site outside the
-USA is in violation of US export laws.

-Beside the separate crypt tar file there are some more add-ons which can be
-used together with GNU libc.  They are designed in a way to ease the
-installation by integrating them in the libc source tree.  Simply get the
-add-ons you need and use the --enable-add-ons option of the `configure'
-script to tell where the add-ons are found.  Please read the FAQ file for
