I agree that the priority is to make merging easy.

I'm also starting to question the benefits vs cost of enabling
-Wshadow.  In particular, warnings that for us to change the name
of function parameters such as "block_found" or "index" make me feel
like this is going too far.

I think it's useful to review the warnings, because it did find some
real situation where we were shadowing another variable from an outer
scope. But I tend to disagree with a good portion of the warnings
I am seeing right now. Add the fact that the warnings also depend
on the host's system includes, and you might be as uncomfortable
as I am...
