Here's what the src/Makefile.in says about it:
## VCSWITNESS points to the file that holds info about the current checkout.
## We use it as a heuristic to decide when to rebuild loaddefs.el.
## If empty it is ignored; the parent makefile can set it to some other value.
It would make my life simpler if this mechanism were removed; that's one of only
two dependencies of Cazaar in the entire build (the other one is in
lisp/version.el). And the fact that the bug went undetected suggests that
the mechanism wasn't very useful.
Anyone want to argue for keeping this? Support removing it? Suggest
something else?
