I didn't: the compiler did.  This omission caused compilation
failures, so I looked into that and found the problem.  But I didn't
try looking for other similar omissions, and even if I'd think about
that (which I didn't), I wouldn't know how to do that.  Is there some
handy set of Git commands to help in this matter?

I hope the reason(s) for these problems could be revealed, because
otherwise we don't really know what we have on master, code-wise.
