[racket] define-match-expander and embedded racket

I looked a bit further down the page to "3m embedding".
That requires the code you're suggesting. So there's no
confusion, I'm trying to embed the CGC version of racket
into my C program.

I also found a "racocgc" in my installation (previously I was
using the 3m version with a --cgc switch). I tried using that,
but to no avail.
