Updating files: 100% (154/154), done.
HEAD is now at 34d3decd Move to sync_cc as the primary testing target while #341 is not resolved
HEAD is now at b8943207 Finally a fix for the build issues with directory targets: (1) Don't delete artifacts in tests as rules often run in parallel and a follow-up rule can need them. (2) By default, don't create dlls in build_files/ as this is more problematic than a unique temporary file path. (3) Rename a confusing f_name to f_path in a few places.
