Disclaimer: I'm quite sleep-deprived at the moment, so please bear with me: the wording could be awkward.

At the moment, std.file.symlink (and, by extension, readLink) is only implemented for POSIX systems. There is an issue open to add Windows support, and since only Vista and later iterations are supported (IIRC), then including a Windows version is a rather low-effort task. However, Windows necessitates that one confers administrative rights to the process calling the pertinent WinAPI function. (In Windows 10, you may enable Developer Mode and pass a flag to the function.) Therefore, given unittests for these functions' Windows versions, anyone who wants to test Phobos on and for Windows must escalate the process. I'm assuming this also extends to the CI pipelines' Windows hosts. I have a few ideas as to how to go about this, but I'm interested in hearing whether what I wrote is sufficient enough to close the issue outright.
