for reporting.
- Fix a race condition with ORTE's session directory setup. Thanks to
@tbj900 for reporting this issue.
- Fix a deadlock issue arising from Open MPI's approach to catching
calls to

problem.
- Fix a problem with PPC atomics which caused make check to fail
unless builtin
atomics configure option was enabled. Thanks to Orion Poplawski for
reporting.
- Fix a problem with use of x86_64 cpuid instruction which led to

Santcroos for reporting this problem.
- Fix a problem when using built in atomics configure options on PPC
platforms
when building 32 bit applications. Thanks to Paul Hargrove for
reporting.
- Fix a problem with building Open MPI against an external hwloc
installation.
Thanks to Orion Poplawski for reporting this issue.
- Remove use of DATE in the message queue version string reported to
debuggers to

McKinstry
for help in fixing this problem.
