I seem to recall a discussion of this on comp.lang.fortran recently, 
where it was mentioned that this restriction was a F95 thing that was 
relaxed in F2003.  Unfortunately, I can't seem to find the comment 
again, but it looks to me like the language in the standard does relax 
the restriction.

If that's true, I'd suggest that this should be a -std=f95 thing, not an 
absolute error.
