[ANNOUNCEMENT] Updated: mingw-runtime-3.18-3

The mingw-runtime package provides public domain implementations of
header files, import libraries, and other support for the MSVCRT C
Runtime Library. It also provides several extension libraries that
(optionally) override certain MSVCRT functions for better standards

These headers and libraries are used by the MinGW cross toolchain, as
well as by the (deprecated) gcc3 compiler in its -mno-cygwin mode.

!!!! 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:

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
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.  Ideally, this package and the accompanying
    i686-pc-mingw32 cross compiler will supplant the old
    'gcc-3 -mno-cygwin' mode.

*** NOTE 1 ***
If, in the month since the updated gcc-mingw packages were released, you
have "fixed" your 'gcc-3 -mno-cygwin' by following the CHOICE ONE
procedure described in
then you will need to "undo" that fix after installing this package. To
do so, simply re-install the gcc-mingw-core-20050522-3 package.

*** NOTE 2 ***
If you have installed the "missing" mingw cross compiler packages from
then you need take no special action.  This package will simply upgrade
the one.

*** NOTE 3 ***
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:
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
  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

* Compiled by and for the i686-pc-mingw32 toolchain. Installs into
  /usr/i686-pc-mingw32/sys-root/mingw/{lib,include} rather than

NOTE: Chris Sutcliff is still the mingw-runtime maintainer, but has
graciously consented to allow this update during the MinGW cross
compiler transition phase.  Future mingw-runtime updates will be
published by Chris, once our cross-compiler teething issues have
settled down.


To update your installation, click on the "Install Cygwin now" link
on the web page.  This downloads setup.exe to
your system.  Then, run setup and answer all of the questions.
