for, not an employee of, the Free Software Foundation (FSF).
As with other GNU software, funding is important because it can pay for
needed equipment, personnel, and so on.
This would tend to result in output that is more consistent
with that produced by some other Fortran implementations.

+to 32-bit or 64-bit values by the compiler
+as ``spills''.
