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.
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.

Move content from glob/* and config/* into standard GNU directory
locations lib/* and m4/*.
Install the gnulib bootstrap script and its configuration file, and
create a bootstrap.bat file for Windows. Update the README.git file
with new requirements and instructions for building from Git.
At this point we only install the alloca, getloadavg, and FDL modules
from gnulib. We keep our old glob/fnmatch implementation since the
gnulib versions require significant amounts of infrastructure which
doesn't exist on Windows yet. Further work is required here.
Due to a problem with gnulib's version of getloadavg, we need to bump
the minimum required version of automake to 1.16.1 unfortunately.
