A little off topic, but a fringe benefit of using the -p flag to 
mkdir is that it never complains about directories which already 
exist. This is even guaranteed by POSIX, which says "Each dir operand 
that names an existing directory shall be ignored without error" when 
-p is used. I often use -p to avoid the loop-and-test above, even 
when making single-level dirs. So the above could just be

__dummy := $(shell mkdir -p $(MKDIRS))

saving both processes and keystrokes.
