Reading this discussion, as a bystander I can't help wondering whether the addition of -O is worthwhile. Unix tools are supposed to be small and dedicated. Using a separate utility seems to be a clean solution here, and that is fact how it was originally done:
http://lists.gnu.org/archive/html/bug-make/2011-04/msg00018.html Using a separate utility is less performant and more cumbersome, but it is more modular. The semantics are clear. The utility can be documented and developed separately from GNU Make. As a GNU Make user I worry that with the -O option I won't be sure how it works. -- Reinier Post TU Eindhoven _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
