If defined, designates the target Windows API version. The version

If the macro is not defined, the version is deduced from <code class="computeroutput"><span class="identifier">_WIN32_WINNT</span></code> and <code class="computeroutput"><span class="identifier">WINVER</span></code> macros, if they are defined,
or the default version is chosen. The default version is currently
Windows Vista/Server 2008 on compilers that support this version
of SDK and Windows XP on others. The default may change in future
releases.

If defined, designates the target Windows API version down to a particular
Service Pack. This macro offers a more fine grained way to define
the target Windows version than <code class="computeroutput"><span class="identifier">BOOST_USE_WINAPI_VERSION</span></code>.
The version should be given as hexadecimal integer, same as the
<code class="computeroutput"><span class="identifier">NTDDI_VERSION</span></code> macro

If the macro is not defined, the version is deduced from <code class="computeroutput"><span class="identifier">NTDDI_VERSION</span></code> and <code class="computeroutput"><span class="identifier">BOOST_USE_WINAPI_VERSION</span></code> macros,
in the latter case defaulting to the latest revision of the indicated
Windows version. If <code class="computeroutput"><span class="identifier">BOOST_USE_NTDDI_VERSION</span></code>
is defined, <code class="computeroutput"><span class="identifier">BOOST_USE_WINAPI_VERSION</span></code>
is also expected to be defined to a corresponding value.
