I'm impressed that you are trying to get this right, even though
clearly nobody really will ever be able to depend on it.

I suspect this part of the patch is more likely to actually be
something that somebody may actually want some day:

  +// We ought to add __builtin_strcmp() support to constant expressions;
  +// what's more, "foo"[0] should also be recognized as one...
  +// Sloppy length check for now...

because yeah, we've actually depended on the compiler just figuring
some of those kinds of build-time optimizations out before to remove
dead code etc.
