No, these are different problems - the one in arg promotion is purely 
about K&R C and trying to match untyped function decls with calls, while 
the type_from_mode bit was about some ptx ideosyncracy. Although I 
forget what the problem was, that code is more than a year old - I'll 
see if I can get rid of this.
