commit 3112c8799358cb5d051e0b63d0e916357169942c
Author: Paul Smith <address@hidden>
Date:   Sat Aug 4 12:18:39 2018 -0400

    Queue failed fork() (etc.) to be handled like any other failed job.
    
    If we failed to fork() we were essentially exiting make immediately
    without respect to ignore flags, etc.  On one hand that makes sense
    because if you can't fork you're in real trouble, but it doesn't
    work so well on systems where we don't fork at all.  Instead, treat
    a fork error like any other error by delaying the handling until
    the next call to reap_children().  Any child with a PID of -1 is
    considered to have died before starting so check these first without
    waiting for them.
    
    * src/commands.c (fatal_error_signal): Don't kill children that
    never started.
    * src/function.c (func_shell_base): Handle cleanup properly if the
    child doesn't start.
    * src/job.c (reap_children): Check for children that died before
    starting and handle them without waiting for the PID.
    (start_job_command): Free memory when the child doesn't start.
    (start_waiting_job): Don't manage children who never started.
    (child_execute_job): If the fork fails return PID -1.
    * src/vmsjobs.c: Check for children that never started.
    * tests/run_make_tests.pl: Parse config.status to get all options.

commit 8bde7db16fa4e51239ece8a83420c580938bda24
Author: Aron Barath <address@hidden>
Date:   Mon Jul 9 09:05:30 2018 +0200

commit 5d985c2851c54df054b416e05f869ff7b0ab40e7
Author: Aron Barath <address@hidden>
Date:   Thu Jul 5 14:53:23 2018 +0200

    * configure.ac: Check for spawn.h and posix_spawn()

commit 3f194b69e37c93a3b5c3e1a5475a5514e71b43cb
Author: Aron Barath <address@hidden>
Date:   Mon Jul 9 07:31:25 2018 +0200

    * src/remote-stub.c (start_remote_job): Ditto.

commit b7acb10e86dc8f5fdf2a2bbd87e1059c315e31d6
Author: address@hidden <address@hidden>
Date:   Wed Jun 20 02:03:48 2018 +0300

    * src/dir.c: Preserve glob d_type field
    
    When using GNU make on a system with glibc glob a pattern ending in
    a slash is also matching regular files, but only in subdirectories:
    
    $ mkdir -p dir/subdir
    $ cd dir
    $ touch file1 subdir/file2
    $ echo 'test:; @echo $(wildcard */ */*/)' | make -f -
    subdir/ subdir/file2
    $ echo 'test: */ */*/; @echo "$?" != */ */*/' | make -f -
    subdir/ subdir/file2 != subdir/ */*/
    
    It happens because in the gl->gl_readdir callback supplied to glob(),
    dirent->d_type is set to DT_UNKNOWN, and the glob() implementation
    in glibc assumes that such a directory entry *cannot* possibly be a
    regular file.
    
    Pass the actual d_type down to glob(); this is the right thing to do
    even if glibc is fixed, because it saves an extra stat() syscall for
    each dirent.
