I don't know whether I qualify or not, but it looks mostly OK to me.  I
may even be able to answer this old question:

} +#endif

The reason for this is so that the shell exits properly if the
terminal is disconnected (window closed, whatever) during the wait.

I think the intention there is to reap any other jobs that exited
while we were waiting for the specified job, because we won't get
the normal SIGCHLD signals for those.  However, I'm note entirely
sure that was necessary or that it accomplished what it meant to.
