ThinLTO cache file access times are used for expiration based pruning and since Vista, file access times are not updated by Windows by default: https://blogs.technet.microsoft.com/filecab/2006/11/07/disabling-last-access-time-in-windows-vista-to-improve-ntfs-performance This means on Windows, cache files are currently being pruned from creation time. This change manually updates cache files that are accessed by ThinLTO, when on Windows. Patch by Owen Reynolds.
