Hmmm. I have been working on chapter 30 as well. Here's my current
status, before you get too far into it.

This is a really good question. 

I think we have to decide what we want

mutex
thread
condition_variable

to mean on systems with --disable-threads, and do it consistently.

I think the choice is either
assume threads and error when not supported, or provide dummy versions
with
distinct linkage from "real" versions that are --enable-thread capable.

best,
