I tried getting rid of this header when I was doing compile-time type
reflection/introspection on Gaby's now-dead branch.  It turned out that
glibc used it for some twisted purpose, even though gcc doesn't.

Behind everything some further thing is found, forever; thus the tree behind
the bird, stone beneath soil, the sun behind Urth.  Behind our efforts, let
there be found our efforts.
