Wouldn't just naming it build-warnings.log suffice? I don't think we
want to actually upload build.txt - it already is captured.

Not sure.

TBH, I'm not quite sure a separate docs task does really still make
sense after the SanityCheck task. It's worth building the docs even if
some flappy test fails, but I don't think we should try to build the
docs if the code doesn't even compile, in all likelihood a lot more is
wrong in that case.

I suspect this is just about dealing with unnamed tasks and could be
handled by just mixing in CI_NODE_INDEX if the task name isn't set.


I pushed a version of 0007-cirrus-clean-up-windows-task.patch. I didn't
rename the task as I would like to add a msbuild version of the task at
some point (it's pretty easy to break msbuild but not ninja
unfortunately). In additional I also removed NO_TEMP_INSTALL.
