Isn't it just a workaround for broken dependencies?No.I mean, considering the following example: all: one two .WAIT three one two three: ; @sleep 1; echo $@ It's the same as if it was written as all: one two three three: one two one two three: ; @sleep 1; echo $@ Isn't it?Only from the point of view of make all; try make three and you'll see the difference. If you make three with the first make file, it'll take one second and just echo three. Passing -j 37 will make no difference. If you make three with the second make file, it'll take at least two seconds (three with -j1) and output one and two (in some order) then three. If you make all with the either makefile, it'll behave like make three with the second makefile, but differently from make three with the first makefile. If any other targets depend on three, they're likewise changed by the second makefile, compared to the first,
Ahh, sure, that's right.However, I don't see why this would be beneficial. Why would A need to be built before B, if there's no dependency between them? I think this is hiding some kind of missing dependency. Maybe this is a workaround for not having post-requisites yet?
