You only notice it now because the "bzr rm" I do caused your cl-loaddefs.el file to disappear, but otherwise this file would normally never disappear except you "make bootstrap". It's a one off transient problem, fixed by "make bootstrap", like many other such transient problems. Actually, you can recreate this file without bootstrapping: "rm lisp/loaddefs.el; make" will do. Of course, on a machine with many CPUs, this ends up taking almost as long as a bootstrap ;-( Stefan
