When I try to use the Golds.inc and/or woods.inc which come with POVRay 3.1,
I got error messages.
PovRay looks like not understanding statements of these files such as :
"#declare GoldBase = <1.00, 0.875, 0.575>;  // mine again

// This set shifts the color toward orange by subtracting
// bluegreen from the base color.
#declare CVect1 = GoldBase  - <0.00, 0.20, 0.40>;"

 or things like 'translate -2*x' and '<0.5,0.5,1>*0.66'

With these statements, I have errors on '*' (which disapeear if I
replace -2*x by <-2,0,0>' for instance) and on the '-' of the substraction.

I don't understand these errors since I perfectly use the same kind of
statements in my own .POV (and they exist on other people's files).

What do you think of this problem ?
