Yup, sounds reasonable. :)

As you wish, of course. But note that "meson compile" is a dispatching
command that first checks whether the build has been setup using a
non-default --backend option instead of the default ninja:

- Microsoft msbuild
- Apple xcode

and then determines which of the three to run. So if you decide to run
"meson compile -C builddir/" it will just in turn run, on your behalf,
"ninja -C builddir/".

It also has the side effect of, if your compiler is MSVC cl.exe, loading
vcvarsall.bat before dispatching to ninja, as a workaround for

https://github.com/ninja-build/ninja/issues/1610

None of that matters for dtc, I guess. :)
