The difficulty metric as I perceive it, graphically:

     GCC -------> GCC ----------------------------------------> XLC
    ASCII        ASCII                                         EBCDIC
    Intel          z                                             z
little-endian  big-endian                                    big-endian

(But then, I hate EBCDIC!)
