<br>
I'm trying to use clang-cl on Windows to be able to use ASAN. The<br>
build system I'm using is a little wonky, so I worked around it by<br>
putting the Clang build output dir in the executable search path, and<br>
creating a link from cl.exe -> clang-cl.exe there.<br>
<br>
So far, so good -- clang-cl is compiling the code when I build from<br>
Visual Studio.<br>
<br>
But as soon as it hits an <ostream> include, I get build errors from<br>
Clang's intrinsics headers, e.g.:<br>

Did I miss anything here? I'm not telling clang-cl anything about<br>
target, I did try passing various /arch: arguments without any<br>
success.<br>
<br>
Thanks for any ideas!<br>
