I hope this is in addition to putting the binaries in a versioned 
directory with the _same names_ as they have always had?

I've worked with multiple simultaneous builds for years, covering 
multiple major versions and the only thing that kept things sane was 
setting up the environment per-shell. Keeping track of the different 
configure options required through those versions was bad enough. 
Tracking different binary names across different builds would be 
terrible (not to mention making re-use of command history really painful).
