I've been wondering about this when I first added it to the Makefile, and I couldn't really find a rationale for it. From the documentation of GNU make: http://www.gnu.org/software/make/manual/make.html#Directory-Variables http://www.gnu.org/software/make/manual/make.html#DESTDIR prefix is (conventionally) lowercase, DESTDIR is uppercase, so I'd stick to that. I guess there's just some historic reason behind it. Some Makefiles of long-standing projects use prefix, some PREFIX. By the way, the rest of the series all look good to me (and is very appreciated!). -- Stefano
