            Bug ID: 23883
           Summary: clang-cl incorrectly pass include directories
           Product: clang
           Version: 3.6
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

I'm trying toolset LLVM-vs2013 with my solution, but clang-cl cannot find my
include files:
src\perm.cpp(12,10): fatal error : 'mylib/tools2/perm.h' file not found
  #include <mylib/tools2/perm.h>

clang-cl somehow pass all include directories (/I) as one big -I "..."
parameter.


clang-cl parameters for cpp file:
/Yc"mylib/tools2/perm.h" /GS /analyze- /W3 /Zc:wchar_t

It would be great if it will be fixed in the next version
