The k&r-style function definitions apparently amused only me, but are beside the point regardless.

Single-pass compilation is very pertinent. One tenet of c's design is that it should be compilable in a single pass (which is why it is compilable in a single pass, unlike many other programming languages). This is relevant to us because it allows us to make predictions about the language; in particular, if the addition of some feature would cause c to not be compilable in a single pass, we can predict that the feature will not be added to the language. Notice that I have not made any value judgments. You may disagree about the importance of supporting single-pass compilers, but I am not the person you need to convince of that.
