+<h3>Whole-Program Optimization for MS Visual Studio Targets</h3>
+
+<p>When using the Microsoft compilers a new build system variable is provided
+that controls whether whole program optimization is used or not. For static
+builds using Visual Studio 2010 this optimization must be disabled. This is
+controlled in the files configure/os/CONFIG_SITE.Common.windows-x64-static and
+configure/os/CONFIG_SITE.Common.win32-x86-static by setting the variable
+<tt>OPT_WHOLE_PROGRAM&nbsp;=&nbsp;NO</tt> to override the default value
+<tt>YES</tt> that would otherwise be used.</p>
+
+<p>Note that enabling this optimization slows down the build process. It is not
+possible to selectively disable this optimization, when building a particular
+module say; Microsoft's linker will restart itself automatically with the
+<tt>-LTCG</tt> flag set and display a warning if it is asked to link any object
+files that were compiled with the <tt>-GL</tt> flag.</p>
