</div></div>Why getdlopenflags? That seems general to any Python implementation<br>
that opens dlls (though I believe the dl module is going away in<br>
Python 3, so it may not matter).</blockquote></div></div><div>I don't think any other implementations do open dynamic libs. Those flags don't affect the dl module; they define how Python opens C shared libs.<br></div>

<br>
<br>
Also, maybe settscdump should be moved as well? Its description says<br>
to look at "Python/ceval.c" <br></blockquote></div><div>Yes. <br></div><div class="Ih2E3d"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Otherwise, it looks pretty good to me.<br>
