-* 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.
