It only matters if the patent holder tries to enforce the patent, which 
is realistically not going to happen in this case, because they would 
ultimately lose. The relation to his work is fairly remote, there is a 
massive amount of prior art (it's in TAoCP for god's sake), and it's a 
quite trivial addition to a widely known technique.

For these reasons, my opinion is that the Boost community shouldn't care 
about that particular patent if the code was ever considered for review. 
Of course that opinion is just that of a simple developer with no 
corporate experience, and I'm far from being a lawyer.

I do not know if there ever have been pieces of code rejected due to 
such far-fetched patents. I think there were discussions with a few 
atomic concurrency things and people managed to work around the patents, 
so surely some people know about subject very well.
