I am calling (with ff-call) some c code that requires a pointer to a pointer.
You're right. I don't need a macptr pointing to a macptr. I was
misunderstanding what a macptr was -- I thought it was a C pointer and now
realize it is a more complicated lisp object. What I really need is a
macptr to a 4 byte area which I know how to do.
