 * status:  patch => infoneeded


Comment:

 OK, with `integer-gmp2` on the horizon (Phab:D82), these changes will need
 to be revisited, and we really should have a coherent discussion about
 what to do for the `in-tree` GMP. So I'm bumping this out of `patch`
 status since it still hasn't gone anywhere.
