  39    means the generic argument(s) may be real or complex, _REAL means
  40    real only, _CPLX means complex only.  If there is no suffix, we are
  41    defining a function of one argument.  If the suffix is _n
  42    it is a function of n arguments.  We only define these macros for
  43    values of n that are needed. */
