I was working on that and hit an issue that took me a while to resolve: Once I
tested only the "main" meson commit plus CI the windows task was running out
of memory. There was an outage of the CI provider at the same time, so I first
blamed it on that. But it turns out to be "legitimately" high memory usage
related to debug symbols - the only reason CI didn't show that before was that
it's incidentally fixed as a indirect consequence of using precompiled
headers, in a later commit. Argh. It can also be fixed by the option required
to use ccache at some point, so I'll do that for now.
