It's the bug I referred to earlier in emacs-devel about CL functions.
Just "re lisp/vc-hooks.elc; make" should fix it for now.
What happens is that vc-hooks.el ended up byte-compiled in a context
where subr.el was loaded after cl.el, so while CL was loaded, the `push'
macro was not the CL one but the plainer one provided by subr.el.
And of course vc-hooks.el uses some of CL's added features of `push'.
