[llvm-dev] clang windows 10 headers

[Reid Kleckner via llvm-dev]

Running in a vcvars.bat shell environment should make this work without
changing clang.

Clang only checks these hardcoded paths when the INCLUDE variable isn't
set. This code in clang/lib/Driver/MSVCToolChain.cpp needs work to deal
with the Windows 10 SDK:

    if (getWindowsSDKDir(WindowsSDKDir, major, minor)) {
      if (major >= 8) {
        AddSystemIncludeWithSubfolder(DriverArgs, CC1Args, WindowsSDKDir,
                                      "include\\shared");
        AddSystemIncludeWithSubfolder(DriverArgs, CC1Args, WindowsSDKDir,
                                      "include\\um");
        AddSystemIncludeWithSubfolder(DriverArgs, CC1Args, WindowsSDKDir,
                                      "include\\winrt");
      } else {
        AddSystemIncludeWithSubfolder(DriverArgs, CC1Args, WindowsSDKDir,
                                      "include");
      }
    } else {

If you can easily test changes to this code, a patch would be welcome.
