Yes, they are, and, in my investigations anyway, I haven't found any way to
get rid of them. The meson support for windows is very much targetted at
users of msvc and clang-cl (which uses the msvc-style flags) rather than
regular clang, so the support is not as clean as I would like. Thankfully,
though, it does appear to be working thus far! :-)
