It would be nice to be able to a link to a small piece of documentation that describes:
- what unified build / unified compilation is, and
- why adding or removing cpp files to a directory can break compilation of unrelated files.

As such, this is not a Firefox-specific question. Elsewhere it is also referred to as "unity build:", and described, e.g., in https://en.wikipedia.org/wiki/Unity_build
Are there questions specific to the implementation in the Firefox Build System that should be answered?

Interesting, I wasn't aware of that wikipedia page. What I'm really looking for is just a short blurb that answers the question "Why is the compiler asking me to make changes to files I didn't touch?", that I can link newcomers to.

Describe what unified builds are and how they can cause innocuous
changes to cause unexpected compilation failures.

Note we're not particularly attached to the term. It could make sense to change.
