<p class="MsoNormal">Can someone explain the usefulness of __APPLE_CC__? The documentation claims [t<span style="font-size:10.0pt;font-family:"Lucida Sans Unicode","sans-serif";color:black">he] macro is set to an integer that represents the version number of
the compiler. </span><br>
<br>
But one version of Apple clang defines:<o:p></o:p></p>
<div>
<p class="MsoNormal"><br>
<br>
#define __APPLE_CC__ 6000<br>
<br>
#define __apple_build_version__ 6020053<br>

<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">And another newer version of Apple clang defines:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">#define __APPLE_CC__ 6000<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">So how does __APPLE_CC__ represent the "version" of the compiler? Is it stuck at 6000 now forever?<o:p></o:p></p>
