Boost C++ Libraries: Ticket #9101: __DragonFly__ preprocessor macro not defined for VC++ https://svn.boost.org/trac10/ticket/9101 <p> 7&gt;c:\users\ian\dev\tensor\main\code\external\boost\latest\boost\detail\endian.hpp(50): warning C4668: '<span class="underline">DragonFly</span>' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif' (main.cpp) </p> <p> The other ones are (<span class="underline">NetBSD</span>, <span class="underline">FreeBSD</span>, <span class="underline">ANDROID</span>, etc.), so I assume it is an oversight. And causes C4668 as you can see. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9101 Trac 1.4.3 ianjirka@… Wed, 11 Sep 2013 06:01:19 GMT <link>https://svn.boost.org/trac10/ticket/9101#comment:1 </link> <guid isPermaLink="false">https://svn.boost.org/trac10/ticket/9101#comment:1</guid> <description> <p> Note -- the ticket system has stripped the double-underscore that proceeds and follows each macro name. </p> </description> <category>Ticket</category> </item> <item> <dc:creator>Marshall Clow</dc:creator> <pubDate>Wed, 11 Sep 2013 13:18:50 GMT</pubDate> <title>owner changed https://svn.boost.org/trac10/ticket/9101#comment:2 https://svn.boost.org/trac10/ticket/9101#comment:2 <ul> <li><strong>owner</strong> changed from <span class="trac-author">No-Maintainer</span> to <span class="trac-author">pmenso57</span> </li> </ul> Ticket Edward Diener Sun, 17 May 2015 00:23:49 GMT <link>https://svn.boost.org/trac10/ticket/9101#comment:3 </link> <guid isPermaLink="false">https://svn.boost.org/trac10/ticket/9101#comment:3</guid> <description> <p> The file boost/detail/endian.hpp no longer exists in the latest Boost.
