Number of bits/sizeof int

[Jon Clements]

Hi Group,

This has a certain amount of irony (as this is what I'm pretty much
after):-
>From http://docs.python.org/dev/3.0/whatsnew/3.1.html:
"The int() type gained a bit_length method that returns the number of
bits necessary to represent its argument in binary:"

Any tips on how to get this in 2.5.2 as that's the production version
I'm stuck with.

Cheers,

Jon.
