The mingw-bzip2 package has been updated to version 1.0.6-1. bzip2
is a patent-unencumbered but highly effective compression library;
mingw-bzip2 is a version built using the standard windows runtime
library and NOT cygwin; it is used by setup.exe among other tools.

[[ compiled using mingw-gcc-4.5.2 ]]

!!!!!!!!!!!!!!!!!
!!!! WARNING !!!!
!!!!!!!!!!!!!!!!!
IF you are attempting to update an existing cygwin installation, which
has the gcc-mingw 'add-on' packages installed (*), then you MUST
upgrade the gcc-mingw packages to version 20050522-3 or newer, before
installing this upgrade.  Do NOT attempt to upgrade BOTH gcc-mingw and
this package during the same setup.exe event. The reason for this
restriction is fairly complex, and is detailed here:
    http://cygwin.com/ml/cygwin-announce/2011-04/msg00015.html

If you are reading this announcement AFTER having messed up your cygwin
installation, because you didn't follow these instructions or didn't
know about them, then see the section in this message
    http://cygwin.com/ml/cygwin-announce/2011-04/msg00015.html
that begins with "HELP!!!" and follow the suggestions there to "fix" it.

(*) gcc-mingw packages are "add-ons" to the gcc-3 compiler suite, and
    provide the necessary files for the -mno-cygwin mode of that
    compiler.

**************
*** NOTE 1 ***
**************
If you have installed the "missing" mingw cross compiler packages from
   http://cygutils.fruitbat.org/ITP/mingw-gcc/
then you need take no special action.  This package will simply upgrade
the cygutils.fruitbat.org one.

**************
*** NOTE 2 ***
**************
After upgrading all of the various mingw-packages (that is,
mingw-{runtime,zlib,bzip2,xz,gpg-error,gcrypt} etc.), the following
directories may be empty:
  /usr/include/mingw
  /usr/lib/mingw
This is expected.  Those 'gcc-3 -mno-cygwin' users who wish to continue
rather than switching to the new MinGW cross compiler, may find it
necessary to add -I/usr/i686-pc-mingw32/sys-root/mingw/include when
compiling and -L/usr/i686-pc-mingw32/sys-root/mingw/lib when linking.
However, another workaround for gcc-3 users is to remove the now empty
/usr/{include,lib}/mingw directories and replace them with symbolic
links:
  rmdir /usr/include/mingw
  ln -fs /usr/i686-pc-mingw32/sys-root/mingw/include /usr/include/mingw
  rmdir /usr/lib/mingw
  ln -fs /usr/i686-pc-mingw32/sys-root/mingw/lib /usr/lib/mingw

CHANGES since 1.0.5-10
========================
o Updated to upstream version 1.0.6
o Recompiled by, and repackaged for use with, the i686-pc-mingw32
  cross compiler.
o Changed the name of the DLL from mgwbz2-1.dll to libbz2-2.dll, for
  compatibility with mingw.org distribution.
o Adopt mingw.org changes:
  - export symbols from dll using cdecl calling convention instead of
    WINAPI (stdcall)
  - bump DLL number (and dll package name) to '2'
  - Import autoconf-based build system from mingw.org
  - Add new --show-progress option
