Even if somebody used INTEGER, we need not to worry, because then,
the routine was unusable, because in Fortran there is no integer value
defined for true and false.

Therefore, this routine was unusable.

And, an errata should not have a backward compatibility problem, because
it changes the routine from its beginning ;-)
