<p class="MsoNormal">I think the point here is that this is the default std for GCC but not Clang, so you have to force clang to behave like GCC. For C++, you'll have to force whatever default GCC has for it's C++ standard.<o:p></o:p></p>

<p class="MsoNormal">right, but what option in clang++ forces it close to g++ for running spec2006 ?<br>
<br>
for clang it is apparent -std=gnu89<br>
<br>
i understand that we have it configured already for test-suite but I also need to be able to run this standalone (outside of test-suite).<br>
