Seems like it would be helpful to add a comment in the sources somewhere
so that some future hacker won't go down the same fruitless path.  When
I first started hacking on GCC, I was impressed by the number of #if 0
chunks that were preceded by "you would think this would be the right
thing to do, but here's why it loses", along with the explanation.  You
wouldn't want to do this all the time, but this case seems worth
documenting.
