 Actually Boost.Math is about 4 times slower on my machine with msvc 9.0.
 I was just saying that usign 1/beta vs. beta didn't affect the timings.

 same values when using boost and ATT Bell.

 I'll check again. All I did was to change att_bell and boost_ to return
 value and
 compare the results for the same arguments. They were totally different
 until I switched boost_ to 1/beta.
