I'd imagine that the Cray compiler has always had a "ignore double
precision, always use single precision" flag for exactly this reason.
I haven't used Crays before 1989, though.
In new-style code, the alleged way to do this is with kinds. Which is
the point of the current discussion, that that's ugly.
