Subject: Available for test: cygwin-1.5.1-1

I've made a new version of the Cygwin DLL and associated utilities
available for download.  As usual, a list of what has changed is below.

This version is currently available for testing only.  As in version
1.5.0, it contains major changes in some APIs such that 64 bit file I/O
operations are now available.  This means that some structures such as
those found in 'stat' and 'dirent' have changed.  Older applications
will continue to work correctly but DLLs and libraries which use any
structures whose size has changed will need to be recompiled and

Note that if you have rebuilt an library or application for 1.5.0 and
you are using the fdopen call, you will need to relink your app for
1.5.1.  I'm sorry for the inconvenience.  Executables linked for/with
1.3.22 or earlier should continue to work fine.

If you are maintaining a cygwin package, then you should be subscribed
to the cygwin-apps mailing list, and you should be following the
discussions there about rebuilding for the cygwin 1.5.x series.  If you
are a package maintainer and are not actively following this list, there
is a strong possibility that your package will be pulled from the cygwin

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.
