I don't have any particular problem using 19.2 to make this a feature, not a bug. Clarity is always better. I wonder how does 19.2 square with 8.5.5, lines 13-14: # If the value of the [NAME=scalar-character-constant] is [...] nonzero, # it shall be valid as an identifier on the companion processor. If you ignore the case of an identifier in the C language (the "companion processor"?), I suppose it is still "valid". But it's the wrong one. Oh, well, above my pay grade. Thank you for your investigation, and ongoing work on gfortran.
