Compilation error with MKS tool kit

[Vijaykumar Ramalingam <vijaykumar_ramalingam@xxxxxxxxx>]

Hello All,

I am trying to port OpenGL library (from SGI
distribution) on Windows NT in MKS tool kit
environment. I am getting the following error.
..\Inventor\sbTime.h : error C2678: binary '+' : no
operator defined which takes a left-hand operand of
type 'class SbTime' (or there is no acceptable
conversion)

I have checked the code, but it is fine. Any
suggestion will be appreciated.

Thanks for all.
Vijay
