This patch is wrong.
The original code is basically fine. Normally it doesn't make sense to
have an array of flex arrays, but in this case it "flexes" between 0 and
1. If it were had two elements then the match the math wouldn't work
at all.
We should probably get rid of it and just add some giant comments and
defines to do the math.
But changing it to a pointer isn't right.
