[windows] math.h warnings when using cl from Intel Env (cmd)

I have the following installation:

- Windows 10

- Visual Studio 2015 (community edition)

- Intel 17.0 Update 1 (parallel studio xe composer edition for fortran and C++)

There are reasons to use  VS/cl with ParallelStudio/ifort. Here is a simple code that compiles cleanly with cl with "Visual Studio 2015 x64 Native Tools Command Prompt" - but gives warnings with "Compiler 17.0 Update 1 for Intel 64 Visual Studio 2015 environment"

Perhaps a bug in Intel include files?
