Well .. whatever a 'registered' build is it does this,
the test is ackermann(3,n), the number in [] is the number
of data points, and (min, average, max) is shown.

xlator ghc-6.2.2
        n 10 -[ 14]-> (  0.68,  0.69,  0.72)
        n 11 -[ 18]-> (  2.81,  2.90,  3.01)
        n 12 -[ 13]-> ( 11.72, 12.76, 16.95)

xlator ghc-6.4.1
        n 10 -[  4]-> (  0.20,  0.20,  0.20)
        n 11 -[  6]-> (  0.84,  0.84,  0.84)
        n 12 -[  1]-> (  3.53,  3.53,  3.53)

Of course I won't conclude anything .. :))
