Yeah, I was hoping to avoid that.  I want to know *for sure* that both
binaries were built from the same source.  Keeping separate trees,
especially whey you "cvs update", introduces a risk of having the trees
out of sync.

Shadowing one tree to another introduces the risk of carrying
something from one build environment to the other that should not be
carried.

It is much more ideal to build out of the one source pool into
different build directories.

I seem to recall that at the heart of it was gnu makes "VPATH"
variable.  Not sure how they used it to do this however.

Yes, I did notice that.

Thanx,
