Since a federation determines where the job originated from by looking
at the job's id, the user would have to give a jobid that matches the
origin cluster. Another other option would be to submit jobid specified
jobs as non-federated jobs. But for now this is being disabled.

This is a regression from commit b818dd9d

Basically the first AC_LINK_IFELSE sets whatever compiler we
are using to be that.  Since the above commit removed the BGL/P
code that was linked using C C++ became the compiler since the
next thing was BGQ in configure.ac to test against.

I just grabbed the DATABASES call, but any other one could had
worked.

This is the way it is done with the task plugins.  It appears this only
really matters when requesting 1 task with a full socket with exclusive
access.  This code would cyclically allocate sockets to the step instead
of filling up one socket then going to the next.

Fix for job constraint specification with counts, --ntasks-per-node value,
    and no node count.

With the _DEBUG flag set a typecast was needed in a print statement
  for clean build

Task/cray: Treat missing "mems" cgroup with "debug" messages rather than
    "error" messages. The file may be missing at step termination due to a
    change in how cgroups are released at job/step end.

Was added in 6cfa534f
Was broken in c1513956

When the batch step is launched the node would complain that another
batch step already exists and drain the node. Since this isn't being
used or is documented, this is being removed.

Honor --ntasks-per-node and --ntasks option when used with job constraints
    that contain node counts.

Defer interactive job allocation until ALL allocated nodes are ready
  rather than after PrologSlurmctld (if any) completes.

Only available in squeue with the '-O lastschedeval' format
