  22    the last page of <sys/stat.h>.  The real work is done by the `x'
  23    function which is passed a version number argument.  We arrange in the
  24    makefile that when not inlined this function is always statically
  25    linked; that way a dynamically-linked executable always encodes the
  26    version number corresponding to the data structures it uses, so the `x'
  27    functions in the shared library can adapt without needing to recompile
  28    all callers.  */
