  39    that we lack prototypes for these functions, and we presumably lose
  40    at least in the 64-bit ABI (though that's only supported on Irix
  41    6.5, which I can test).  We may be saved by the fact that these
  42    appear to be intrinsics in the SGI (Cray) compiler.  It's probably
  43    appropriate to include strings.h here, but I can't test it.  See
