CUDA SDK 6.5 - Samples/Common/inc/Helper_Math.h - Missing abs functionality

When I include Helper_Math.h file from the Samples/Commons directory and try to use abs(..) functionality, then I am getting compile errors.

 return make_int3(abs(v.x), abs(v.y), abs(v.z));

As seen, the library is unable to find "abs(int)" function.

I have manually updated the header to find the abs(int) function, but I am looking for a better solution..
