It seems that many of the unit test failures happen when the function 
henon is involved.  This function computes the Henon map with a default 
transient initial period of 10000 samples.  The computation in the henon 
function is iterative and my guess is that the results are sensitive to 
the architecture-specific floating point representation.  Would 
-ffloat-store help here?
