Not quite. The configure script contains hard coded partial paths from
the root of the tree to all Makefiles, including those in
llvm/test/Programs directory. I can't go changing the locations of files
and the contents of the makefiles without also changing configure.ac. If
I change configure.ac then it affects everyone. If it affects everyone,
I need to do it on a branch. I can't do that without cvs access.

So, what you're saying is that I provide you with a patch that excises
all of test/Programs/... from the llvm configure.ac and removes all the
related --enable-xyz options. You check this in. Then what? You've now
disabled your testing environment waiting for a subsequent patch from me
that restores it in "some other directory". Or, were you going to check
the configure.ac change into a branch.  If so, then I have to work out
of a branch that you're administering and we have synchronization
problems.  This is the part that gets time consuming.

I can't retain things in both worlds because autoconf won't configure
anything that isn't in a directory that is a descendant of
${top_srcdir}. 

Gack. 

Can't we just be subversive and use subversion? :) 

You invited that comment :)
