  Sure, it's pointless in a normal build.
  As I understand it, the reason for having TMP_ALLOC_LIMBS_2 is to make
  --enable-alloca=debug more effective, by getting some kind of red zone
  separating the two areas. Whether or not that's worth the clutter, I'm
  not sure.
Surely a plain TMP_ALLOC adds red zones?  If not, that is something we
ought to fix.
