I noticed some issues with the documentation at the top. I wanted to fix them by myself but they're too small for a PR. Can you include the diff?

I guess we won't see any difference in CI because all three environment variables are initially unset.
You should complement my local icu:x64-linux (C_INCLUDE_PATH with separator :) testing with similar icu:x64-windows testing (INCLUDE with separator ;, probably needs to be allowed in triplet file for windows due to environment cleaning).

Fine for me.
I would say there is a small window to collect some changes to this particular script now. I'd also review PRs against my fork, but there is no CI before it arrives here.

This fixes a serious problem and already passed CI, so I'm just merging it for now. Feel free to submit another PR with additional changes.

Thanks!
