Title: Inline definition manually to make it truly constant

Compilers aren't able to figure out that they could inline the cubic
function and get a truly constant value out of the expression. This
causes a warning that there is a variable that isn't used.

I believe I was the one that submitted the original patch -- oh! the irony. Bad karma and all that.
