Ok, I found the subtlety in the documentation that automake in effect uses autoconf's directory or output list.
So if I give up non-recursive make, and if I list directories twice, then it works nicely: i.e. non-recursive make, less modular automake: http://github.com/jaykrell/j/tree/master/auto1 recursive make, more modular automake, have to list directories twice; once is almost enough, but you need to tell automake the directories for the recursion to occur -- could almost hand-write the top level Makefile instead: http://github.com/jaykrell/j/tree/master/auto2 Ideal would be to say dirs=prog lib, instead of output prog/makefile lib/makefile, and ideally would get faster non-recursive make. That is, auto1 has ideal performance, non-ideal, less-modular authoring. auto2 has non-ideal performance and close to ideal authoring. Advise?
