True. And that may very well be an improvement, but it wouldn't make it so 
that the release and debug versions (or 32-bit or 64-bit when the time comes) 
end up in separate directories where they won't stomp on each other. So, while 
the pull request associated with that enhancement request may solve my 
immediate problem (which would be fine with me for the short term), I think 
that the makefile should still be adjusted in the long run.
