- there, the argument seems to be the same, though the reference is R544.

The question is whether one needs to allow it.
g95 and gfortran allow the code
ifort, NAG f95, g77 (!), pathf95/openf95/crayftn reject it.
PGI warns "Symbol, i, appears illegally in a SAVE statement"
Thus, I wouldn't mind breaking the backward compatibility.
