Any comments?

Subject: Updated: cygwin-1.5.3-1

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
relinked.  This is the first non-test version of cygwin with these

There have been two problems with previous 1.5.x releases.  One involved
any application that used fdopen and another involved any application
that used -lc on the command line.  If you have rebuilt a library or
application for 1.5.0 or 1.5.1 and you used either of these, you will
need to relink your app for 1.5.3.  I'm very sorry for the
inconvenience.  Executables linked for/with 1.3.32 or earlier should
continue to work fine.

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.
