I cannot reproduce this with today's master branch.  Suggest to run
"git clean -fdx" followed by "git pull" and a full bootstrap.  I'm
quite sure there's something wrong with your cloned repository, since
the error message about filelock.c makes no sense.  If nothing else
helps, make a fresh Git clone.
