   *  =============

   *> \verbatim
   *>
   *> IEEECK is called from the ILAENV to verify that Infinity and

   *  Arguments:
   *  ==========
   *
   *> \param[in] ISPEC
   *> \verbatim
   *>          ISPEC is INTEGER
   *>          Specifies whether to test just for inifinity arithmetic
   *>          or whether to test for infinity and NaN arithmetic.
   *>          = 0: Verify infinity arithmetic only.
   *>          = 1: Verify infinity and NaN arithmetic.
   *> \endverbatim
   *>
   *> \param[in] ZERO
   *> \verbatim
   *>          ZERO is REAL
   *>          Must contain the value 0.0
   *>          This is passed to prevent the compiler from optimizing
   *>          away this code.
   *> \endverbatim
   *>
   *> \param[in] ONE
   *> \verbatim
   *>          ONE is REAL
   *>          Must contain the value 1.0
