The error is on line 65 ("return(zp->d);"), so I would guess the mplab compiler doesn't support return(a). Try changing the return statement to "return zp->d;"
As is implied above though, using this function may not be a good idea. The pow function is not intended for small imbedded microprocessors and relies heavilly on floating point operations. It is designed for a full size computer. Running this function on the robot controller will slow it down a lot. You can try it and see if anything weird happens, but I would try and find another way to solve the problem, if possible. When you try it, watch out for weird behavior of the robot, that is a good indication that you are putting too many operations into the 26ms loop.
