  notes for Cygwin users</a>
      </h5>
<p>
        Cygwin support is very preliminary. The default GCC version available in
        Cygwin (4.5.3 as of this writing) is unable to compile the library because
        of compiler errors. You will have to build a newer GCC from sources. Even
        then some Boost.Log functionality is not available. In particular, the socket-based
        syslog backend is not supported, as it is based on <a href="http://www.boost.org/doc/libs/release/doc/html/boost_asio.htm
