@JDevlieghere Note that this cleans up about 80% of it. There's still one `%build` usage and quite a few `TestBase.build()` ones, which end up using the wrong compiler. But I left cleaning those up for when I have more time as cleaning those up is a little more involved. There's also some UNIX extension usage I'd like to make explicit at some point.
