Could this bit be keyed off of the calling convention, rather than off 
of is_fortran()?  I think we should be trying to minimize 
language-awareness here.  So, if we've set the calling convention 
attribute earlier, we could remember that, and then use that here.  That 
will make handling future languages with similar calling conventions easier.
