Been avoiding that pattern for years because I swear some make implementation I used at one point was very unhappy with that, but if V7 does it, then whatever implementation that was is probably not what I want to be using anyway. For years, I carried around some early version of make source. Maybe Sys III make? It wasn't fancy but it behaved how I understood it should behave and all the other makes, ESPECIALLY gnu make, were adding features like crazy and, while cool, they were not portable. I really like stuff that Just Works (tm) and really early make felt like that. I'm a dinosaur, there was a saying at my company "Oh, that was invented after 1980, Larry won't let you use that" which was mostly correct but I let you use stuff like mmap(). Also not that portable but oh so useful when it worked. --lm
