Boy of boy.... FPC 2.3.1 is becoming frustrating!!

So is there a performance difference between:
   inc(i,2)    vs    i := i + 2;


If not, then can the += operator rather use the latter?  After all,
just about every peace of documentation on += operator I could find,
they mention that it's an shorthand form of x := x + y
