It only allows one to write Makefiles that use your private choice of shell, and you can do anything you want, I think, as it is now. Your next paragraph, where you give "csh" as an example, it (I think) a perfect counter-example, because (as we all know) csh is a horrible scripting language, but I bet it gets used. Not only that, but one will end up having hav have 15 different shells installed on machines, just to build things that require odd shells. Just so you don't have to use sh. The idea of being able to use your own shell is great, until you think about how you're opening the door to abuse of it. > I'd like to get public opinion on this change to see if many others will > find it useful.
