Hello,<br><br>I have some projects based on Jamfile.v2,which work fine (bjam --v2) with boost cvs code i checked out 12/10/2006 at WindowsXP/VC++express. I just checked out the latest boost cvs code and with this checkout I am seeing some strange compiling errors for the same project and same code. 
<br><br>with &quot;bjam -d+2&quot;, i am seeing exactly the same compiling commands executed in both cases:<br>&nbsp;&nbsp;&nbsp; call &quot;G:\Program Files\Microsoft Visual Studio 8\VC\vcvarsall.bat&quot; x86 &gt;nul<br>cl /Zm800 -nologo @&quot;..\..\..\..\bin.v2\libs\channel\example\gui_evt\msvc\debug\threading-multi\gui_evt_chan1.obj.rsp&quot; 
<br><br>However the compiling pass in old cvs code (12/10/2006) and failed in the latest cvs checkout.<br><br>Any idea? and suggestions where i should start looking into it?<br><br>Thanks<br>Yigong<br><br><br>
