Are you using the exact same code on all platforms for trancendentals
and other floating-point functions? If not, that is going to be the
greatest source of different results. They tend to vary widely on
accuracy, since there is no 1/2 ULP accuracy requirement for those
functions, unlike for the defined IEEE operations (+,-,*,/,sqrt)
