I have updated syslog-ng on cygwin.com to the latest stable release
2.0.7.  The Cygwin version is called 2.0.7.1.  It's taken from the
current state of the syslog-ng upstream git repository, which contains
Cygwin related patches beyond the official 2.0.7 release.

Please read /usr/share/doc/Cygwin/syslog-ng.README for postinstall
information.  I also recommend to visit the /usr/share/doc/syslog-ng/
directory and the man pages "syslog-ng" and "syslog-ng.conf".

Changes since 2.0.5:

        IMPORTANT NOTES:
        * There are two possible Denial of Service fixes in this version of
          syslog-ng, therefore it is strongly recommended to upgrade to this
          version.

        Bugfixes:
        * Fixed UNIX domain socket destinations on Solaris.
        * Fixed flow-control behaviour for follow-mode source files.
        * Added the "mark" keyword to be an alias of "mark_freq" for
          compatibility with syslog-ng 1.6.
        * Fixed message loss in destination files during configuration
          reloads if syslog-ng is heavily loaded.
        * Fixed a possible segmentation fault in the dns-cache-host() file
          parsing code for improperly formatted host files.
        * Fixed possible "Insufficient buffer space" errors in the STREAMS
          driver.
        * Fixed the starvation of the timer used to reap unused destination
          files, which could cause some files never to be closed under
          heavy load.
        * Fixed ISO timestamp parsing for timestamps that have no
          timezone information or have a too long fraction of a second
          portion.
        * Added a workaround for possible deadlocks on /proc/kmsg and
          user terminals.
        * HP-UX related build and runtime fixes, backported from the Premium
          Edition.
        * If unable to resolve the name of the target host, syslog-ng failed
          to initialize the TCP/UDP destination drivers.
          This behavior has been corrected.
        * Corrected program name parsing in incoming messages.
        * Fixed a problem in handling messages which lacked explicit timezone
          information, but the administrator specified a timezone for the
          messages.
        * Fixed some minor memory leaks in configuration reloads.
        * Fixed a segmentation fault which occurred when the timestamp of the
          incoming messages did not end with a space character (NULL pointer
          dereference). This is an easy Denial of Service possibility.
        * Fixed a segmentation fault which occurred when the PID macro was used
          and the message had a closing bracket (']') before an opening
          bracket ('[').
        * Fixed a possible segmentation fault for UDP6/TCP6 destinations.
        * Fixed IPv6 scope id resolution for link-local addresses.
        * Solaris related fixes.

        Other changes:
        * The fsync() option was implemented.
        * Added support for file sources that do not exist at startup.
        * Added support the "--persist-file" configuration option.
        * Added support for timestamps used by some LinkSys routers.
        * Added loggen tool to generate syslog messages at the specified
          rate.
