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].

in doing a port, please contact the glibc maintainers by sending

electronic mail to <bug-glibc@gnu.org>.
|

|

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
|
||||
more details.
