I have a fraction of code using BGL that the MS compiler has for some reason optimized into oblivion. While this is not a boost problem per se, since it appears in a compiler I have not had problems with, I suspect all those templates are confusing the MS compiler somehow. 
<br><br>The symptom is that when I get a property of an edge, then test on that property and branch, the test is removed from the compiled assembly. <br><br>Here is the code: <br>//header<br>typedef property&lt;edge_weight_t, unsigned&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; EdgeCountProperty;
