- *  Purpose
- *  =======
- *
- *  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.
- *
- *  Arguments
- *  =========
- *
- *  DIN1     (input) DOUBLE PRECISION
- *  DIN2     (input) DOUBLE PRECISION
- *          Two numbers to compare for inequality.
