<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Instead of creduce, I would first look at reducing the header-file overhead. Can you reduce the number of headers in your source? Windows is particularly
prone to pulling in boatloads of headers that you don't actually need. If you do need all the headers in your original source, but you are including say <windows.h> along with everything else, there are some preprocessor symbols you can set to reduce that
overhead and so (we hope) get the preprocessed source down to where you can file the bug.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">For example, you could try defining WIN32_LEAN_AND_MEAN and see if that helps. There are probably other symbols you can set to reduce the header overhead, but
that's the one that I remember getting the most benefit.<o:p></o:p></span></p>
