Appendix C is not normative. We only document incompatibilities related 
in the normative text. The normative text in f95 leaves this case 
ambiguous, and the point of the interp was to fill in holes and clarify 
those ambiguities.  For practical reasons, I prefer the answer in the 
interp.  It makes intuitive sense, and it's what (at least our) compiler 
does already anyway.

Cheers,
Bill
