Recursive `make` and `-j`

    The `-j` is meant for the top-level invocation only, and the $(MAKE) pattern is standard.

    The `+` or $(MAKE) "tricks" to ensure the jobserver is inherited in submake and any other subprocess are no longer needed in gmake 4.4 (from 2022) because it defaults to a FIFO instead of pipes. The author should just upgrade gmake :).

      Has Apple backported anything recent to their forked gmake? Have they ever backported any features for that matter?

        Apple does not ship any version of gmake. The only included make is BSD make.

          On my machine (Golden Gate):

             [2026-10-01 9:35:10] % which make
   /usr/bin/make
   [2026-10-01 9:35:39] % /usr/bin/make --version

            You can get an updated gmake via brew.

      you may still need + to forward the job server to other builder <a href="https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;cargo&#x2F;issues&#x2F;14407" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;cargo&#x2F;issues&#x2F;14407
