Follow-up Comment #4, bug #46261 (project make):
The offending code...
#else
/* Set interruptible system calls, and read() for a job token. */
set_child_handler_action_flags (1, waiting_jobs != NULL);
got_token = read (job_rfd, &token, 1);
saved_errno = errno;

I think you’re missing the fact that nobody is actually working on
these things. Make is an open-source project and not one of the ones
that has direct corporate backing or engineers paid to wor
A tiny patch for the documentation, adding a missing comma.

Follow-up Comment #8, bug #46261 (project make):
The remaining failure in the build of FSF gcc 5.2.0 with make 4.1 on OS X
10.11 under perl may actually be a latent bug in the libjava Makefiles being
re-exposed. It is identical to one that I previously reported...

Follow-up Comment #7, bug #46261 (project make):
using
EINTRLOOP(job_rfd, dup (job_fds[0]));
instead of
job_rfd = dup (job_fds[0]);
in the new_job() subroutine of job.c results in a hang during the parallel
build of gcc 5.2.0 rather than the previous error...

Follow-up Comment #6, bug #46261 (project make):
How do we know that the earlier call to duplicate the file descriptor in the
new_job() subroutine of job.c succeeds?
/* Make sure we have a dup'd FD. */

The full error that we are seeing on OS X 10.11 under make 4.1 called from
perl after a flock() is...

Follow-up Comment #3, bug #46261 (project make):
There seems to still be missing EINTRLOOP () macro usage on OS X 10.11. The
gcc 5.2.0 parallel build still fails but the initial error in its case is...
make[5]: *** read jobs pipe: No such file or directory. Stop.
...ending with...
make: INTERN
