There are all sorts of problems arise when you start hiding things from 
make ;-). For example, in the original makefile, if make gets interrupted 
in the middle of the command that creates that "hidden" file there is no 
way make can clean it up. 

BTW, the same thing happens with advanced auto-dependency generation and
it bit me a few times already. I still don't have a solution for this...
