I'll probably open a bug on this, but I just tried using clang.exe 3.5.0<br>
built with either MSVC or MinGW-w64-win32threads. When built with MinGW-w64,<br>
clang.exe is too promiscuous in terms of where it picks up system headers.<br>
It found a set of <a href="http://mingw.org" target="_blank">mingw.org</a> headers installed elsewhere on my system<br>
(definitely not on my path) which it proceeded to error on:<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">So, would love if clang could be a more self-sufficient toolchain and stop<br>
picking up headers from strange places that just happened to be sitting on<br>
my hard drive in the default install location, since those headers were not<br>
used to build clang at all.<o:p></o:p></p>

<p class="MsoNormal">I was under the impression that we were trying to move a away from this "clang picks up headers from the toolchain it was built with" logic? Clang's default triple is determined at configure time which is a bit unfortunate. I think most
people would agree that msvc compatible triple should be the default for windows version of clang.<o:p></o:p></p>
