I don't know what counts as "completely reengineering it", but I gather we could get quite a long way by introducing "parallelizable regions", with explicitly named shell variables and other properties (say config.h matter) as inputs and outputs (plus enabling macros to add to inputs and outputs), and having autoconf generate a configure script, script fragments for the regions, and a Makefile with the dependencies inferred from explicit and implicit inputs and outputs. The configure script would then attempt to run make, or run the fragments serially. -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer Disinformation flourishes because many people care deeply about injustice but very few check the facts.
