| While the current implementation does not follow symlinks, the deletion of source | ||
| files during a build operation is a security issue. This could potentially lead to | ||
| arbitrary file deletion if combined with symlink-following behavior in future | ||
| versions or specific system configurations. |

There was a problem hiding this comment.
Well, as demonstrated, we CAN delete headers outside of the project directory on windows without the need for symlinks.
…during configure (haskell#317)
