[cfe-dev] [clang-tidy] Using clang-tidy on Windows

[Paul Hoad via cfe-dev]

Sorry sorry in advance if this is a newbie question, I'm trying to get
clang-tidy (3.8.0 trunk) working on Windows pointing at the with the Visual
Studio 2015 headers (VC and UCRT)

I'm trying a very simple programme
-------------cut-------
#include <iostream>

void main(int argc,char **argv)
{
   std::cerr << "Hello World" << std::endl;
}
-------------cut-------

clang-tidy will work perfectly until I start include system headers,stl
etc...

I run on the command line (inside cygwin bash shell) with the following.

clang-tidy Stdio.cxx -- -I"c:/Program Files (x86)/Microsoft Visual Studio
14.0/VC/INCLUDE" -I"c:/Program Files (x86)/Windows
Kits/10/Include/10.0.10150.0/ucrt"


but I get a load of failures due to clang errors in the system headers.

Can I:

1) parse a switch to clang-tidy to tell it not to complain about headers
outside of my control?
2) avoid this problem in the first place (I get the same if I try to
compile with clang.exe or clang-cl.exe)?
3) am I making an obvious mistake?
