My understanding is that we do not allow // comments or mixed
declarations and code (other than loop control variables).
This code in particular was very heavily into using mixed declarations
and code throughout. Removing those was moderately painful.

Just stuff from upstream I didn't take out.

Probably not, but otherwise I did not remove much in the way of upstream
comments or edit them except for formatting.

Well, it's probably still useful to point out that they're generated
(though not by us); I guess it should make clear where the generator is.

Maybe, but presumably nothing else is going to include this file.
