commit 0c5a9f9b92af1634dc60fa21e9ac86ed50e5d595
Author: Paul Smith <address@hidden>
Date:   Mon Oct 30 12:53:49 2017 -0400

    * main.c (main): [SV 48274] Allow -j in makefile MAKEFLAGS variable.
    
    * tests/jhelp.pl: New file to allow testing parallelism without sleep.
    * tests/scripts/features/parallelism: Test this.
    * tests/scripts/features/jobserver: Update tests.
    * tests/scripts/features/output-sync: Remove useless rm command.

commit 6264deece3bb77798240a906ceed79097adbcf48
Author: Paul Smith <address@hidden>
Date:   Sat Oct 28 18:45:30 2017 -0400

    * job.c (child_error): Modify error message string.
    
    Ensure Emacs compile-mode's next-error doesn't match target failure
    messages.  Syntax errors in makefiles are still matched.

commit 193f1e81edd6b1b56b0eb0ff8aa4b41c7b4257b4
Author: Paul Eggert <address@hidden>
Date:   Sun Sep 24 09:12:58 2017 -0400

    glob: Do not assume glibc glob internals.
    
    It has been proposed that glibc glob start using gl_lstat,
    which the API allows it to do.  GNU 'make' should not get in
    the way of this.  See:
    https://sourceware.org/ml/libc-alpha/2017-09/msg00409.html
    
    * dir.c (local_lstat): New function, like local_stat.
    (dir_setup_glob): Use it to initialize gl_lstat too, as the API
    requires.

commit d8728efc80b720c630e6b12dbd34a3d44e060690
Author: Paul Smith <address@hidden>
Date:   Sat Sep 23 15:55:37 2017 -0400

    Compute load from number of running processes.
    
    * job.c (load_too_high): If /proc/loadavg is available, compare the
    maximum load against the number of processes currently running.  If
    we can't parse /proc/loadavg, use the previous algorithm.
    
    Concept and initial patch from Sven C. Dack <address@hidden>
