[ANNOUNCEMENT] New on sourceware: unzip-5.41-1

I have removed the 'test' designation from the 'unzip-5.41-1' package,
although it may take some time for the new status to propagate to the
mirrors.  UnZip is an open-source, command-line alternative to other
zip-format archives such as WinZip, etc.  unzip-5.41 is the latest
release from Info-Zip,
ftp://ftp.freesoftware.com/pub/infozip/unzip.html .

I've had unzip-5.41 on the CygUtils site
( http://www.neuro.gatech.edu/users/cwilson/cygutils/V1.1/ ) for some
time, but that version had a few problems:
  1) it was built using windows-ish rules, so it didn't understand
symlinks
  2) had a few problems with text-mounts
This version is built as a unix-ish application, and hopefully I've
cleared up the remaining text-mode issues.  Furthermore, this package
follows the standard packaging rules for 'official' cygwin packages --
installs into /usr, includes documentation in /usr/doc/, etc.

If you have the CygUtils version installed, use the
RemoveObsoletePackages tool at
http://www.neuro.gatech.edu/users/cwilson/cygutils/V1.1/usr-local/Obsolete.html
and follow the instructions to remove it.

INSTALLATION:

To update your installation, click on the "Install Cygwin now" link on
the http://sources.redhat.com/cygwin web page.  This downloads setup.exe
to your system.

Run setup and answer all of the questions.  PLEASE, PLEASE, PLEASE
choose a mirror site for your download.  The 'sources.redhat.com' site
is badly overloaded. 

ftp://ftp.freesoftware.com/pub/sourceware/cygwin/ (US)
ftp://ftp.franken.de/pub/win32/develop/gnuwin32/cygwin/mirrors/cygnus/
(Germany)
ftp://ftp.ntua.gr/pub/pc/cygwin/ (Greece)

The setup.exe program will figure out what needs to be updated on your
system and should install the zip package automatically. 

If you have questions or comments, please send them to the Cygwin
mailing list at:  cygwin@sources.redhat.com .  I would appreciate if you
would use this mailing list rather than emailing me directly. This
includes ideas and comments about the setup utility or Cygwin general.

If you want to make a point or ask a question the Cygwin mailing list is
the appropriate place.

NOTES:

o Building the package from source requires gcc-2.95.2-5 and
binutils-20001029-2 or later

o Abides by the cygwin package system standard:
  - binaries        /usr/bin/unzip.exe, funzip.exe,
                    unzipsfx.exe, zipinfo.exe, zipgrep
  - cygwin-specific docs in /usr/doc/Cygwin/unzip-5.41.README
  - generic docs in /usr/doc/unzip-5.41/*

o A cygwin-specific README and PATCH are stored in the source archive,
under <top>/CYGWIN-PATCHES/* (although that patch has already been
applied to the archive itself). The cygwin-specific README is also
installed by the binary distribution as described above.

o This package WAS built with decryption support -- although the 
corresponding zip package does NOT include ENcryption support. The
unzip-5.41 code base contains decryption support by default, without
using the zcrypt29.zip package at
ftp://ftp.freesoftware.com/pub/infozip/src/zcrypt29.zip .  (Blame US 
cryptography export code; at present, the export of decryption 
binaries and encryption source code rules have been relaxed although
the export of encryption binaries still requires explicit notification 
of the US govt.)

o this build is -mno-win32 clean; that is, it builds from source
identically, regardless of whether gcc sets the _WIN32 or WINNT
defines.
