  25    function which is passed a version number argument.  We arrange in the
  26    makefile that when not inlined this function is always statically
  27    linked; that way a dynamically-linked executable always encodes the
  28    version number corresponding to the data structures it uses, so the `x'

  30    all callers.  */
