   *       LOGICAL FUNCTION DLAISNAN( DIN1, DIN2 )
   * 
   *       .. Scalar Arguments ..
   *       DOUBLE PRECISION   DIN1, DIN2
   *       ..
   *  
   *
   *> \par Purpose:
   *  =============
   *>
   *> \verbatim
   *>
   *> This routine is not for general use.  It exists solely to avoid
   *> over-optimization in DISNAN.
   *>
   *> DLAISNAN checks for NaNs by comparing its two arguments for
   *> inequality.  NaN is the only floating-point value where NaN != NaN
   *> returns .TRUE.  To check for NaNs, pass the same variable as both
   *> arguments.
   *>
   *> A compiler must assume that the two arguments are
   *> not the same variable, and the test will not be optimized away.
   *> Interprocedural or whole-program optimization may delete this
   *> test.  The ISNAN functions will be replaced by the correct
   *> Fortran 03 intrinsic once the intrinsic is widely available.
   *> \endverbatim
   *
   *  Arguments:
   *  ==========
   *
   *> \param[in] DIN1
   *> \verbatim
   *>          DIN1 is DOUBLE PRECISION
   *> \endverbatim
   *>
   *> \param[in] DIN2
   *> \verbatim
   *>          DIN2 is DOUBLE PRECISION
   *>          Two numbers to compare for inequality.
