I'm very much in favor of this change but a deprecation warning is not 
enough - some suitable replacement should be provided to cryptographers 
and other bit fiddlers.

Proposal:

A standard module implementing the types [u]int[8|16|32|64]. These types
would behave just like C integers - wrap around on overflow, etc and have 
a guaranteed size regardless of platform. They can even have methods for
bit rotation.
