In order to create symlinks on windows you need to be an Administrator (or have the permission to create symlinks) or, on newer Windows 10 builds, you can do so _iff_ the developer mode is active.

BUT as a compiler, it should not require any privilege...

This digest symlink is an optimization, failing to update it just means you will get an extra cache miss later.

This is news to me. In this case the code should be modified to not use a symlink to store the hash. File contents will do just as well. Using a symlink was just a way to do fewer syscalls since the file contents is only a few bytes.

Closing this now in favor of #6500
