autoloads generally don't lead to compilation breakages, do they?  You
can't autoload a macro meaningfully, or a variable...

I am no make expert at all, so I don't quite know what that would look
like.

My thought was that if file A.el depended on file B.el, and B.el has
changed, then there would just be a step in the compilation process that
deleted both A.elc and B.elc, and then the rest of the process would
continue on as before.

(We need to delete B.elc because otherwise `(require B)' in A.el would
load the old B.elc, and A.el might be byte-compiled before B.el.)
