Justine Tunney 2bd1e72d5a Remove garbage collector macro from header (#114)
We can put this back the moment someone requests it. Pain-free garbage
collection for the C language is pretty cool. All it does is overwrite
the return address with a trampoline that calls free(). It's not clear
what it should be named if it's made a public API.
