The Intel 2016 compiler suite apparently only partially supports the
!GCC pragmas (prior versions either didn't support it at all, or our
existing configure test was sufficient to disqualify !GCC pragma
support when compiling with the Intel compiler).
With the existing configure test, the Intel 2016 compiler suite would
*pass* the test and therefore think that it could use !GCC as the
"ignore TKR" pragma. However, the "!GCC ATTRIBUTES NO_ARG_CHECK"
pragma doesn't work with scalar integers (although it seems to work
for the other types in this test).
This commit adds a scalar integer test to the ignore TKR pragma
configure test, which is enough to make the Intel 2016 compiler suite
fail with !GCC (this then allows configure to advance on to trying the
!DEC pragma, which *does* work properly with the Intel 2016 compiler
suite).
Thanks to Fabrice Roy for reporting the problem.
Fixesopen-mpi/ompi#937.
As of v15.7, the PGI Fortran compiler does not properly support how
Open MPI uses the "USE ... ONLY" Fortran syntax to include modules
with conflicting symbol definitions (interestingly, pgfortran only has
a problem with this when compiling with -g).
In short, OMPI uses "USE :: module_aaa, ONLY: foo" and "USE ::
module_bbb, ONLY: bar" to use modules aaa and bbb, even though they
contain conflicting definitions for some symbols. However, the use of
the ONLY clause should preclude the inclusion of the conflicting
symbols -- as the word implies, it should direct the compiler to
*only* use the symbols identified by the clause (i.e., foo and bar, in
this example).
This commit adds a configure test for this capability. If the
compiler fails to build a simple test that mimics this behavior, then
disable the mpi_f08 bindings.
Fixesopen-mpi/ompi#857
Only set OMPI_FORTRAN_BUILD_SIZEOF to 1 if $ompi_fortran_happy is also
1 (i.e., we're building the Fortran interface). This prevents
building [p]size_f.f90 and trying to compile it if there is no Fortran
compiler, for example.
This commit removes alpha asm support. No current processor
manufacturer makes chips compatible with DEC alpha and no
participating organization has alpha processors. This makes it
difficult to support alpha via assembly.
This doesn't mean Open MPI will no longer build/work on alpha
processors. It should continue to work with gcc's builtin sync
atomics.

Fortran uses objects (ompi_f08_mpi_comm_world, mpi_fortran_bottom,, ...) that are defined in C.
Some compilers have different requirements on how these objects should be aligned.
Smaller alignment in C can lead to several confusing warnings from the linker, so try to
find the alignment expected by Fortran compiler, and inform the C compiler.

Fujitsu compilers used with the GNU compatibility option (-Xg)

This adds a check at `make install` time to look for common symbols. It
attempts to ignore "Fortran-shaped" symbols by default. It also will

allowed).

== Short version
Do not export special variables into the environment (e.g., LIBS,
LDFLAGS, etc.) when invoking subdir configure scripts. This prevents
problems described in open-mpi/ompi#471.
== More detail
Exporing special env variables before invoking a subdir configure
script causes problems in some cases. E.g., in open-mpi/ompi#471,
when the user configures with `--with-hwloc=/path/to/hwloc`, and that
directory is *not* in a default linker search location will cause the
libevent subdir configuration to fail.
This happens because:
1. We'll pass LIBS="-L/path/to/hwloc/lib -lhwloc" to the libevent
configure script
1. Meaning: configure-generated executables will link successfully
1. But unless LD_LIBRARY_PATH (or some other
tell-the-linker-where-to-find-things mechanism) includes
/path/to/hwloc/lib, the executable can't run.
Specifically, the libevent "hey, does the compiler generate proper
executables?" check will fail, and configure will abort (because OMPI
needs libevent).
I checked the history: exporting these vars dates all the way back to
LAM/MPI. I can't think of a reason why we need to export these
variables -- AC_CONFIG_SUBDIRs doesn't do it; subdir configure scripts
should be orthogonal from the upper-layer configure script (and its
variables). So let's remove these export statements and see if
anything breaks.
Some versions of clang (at least >= 3.5 -- perhaps older versions,
too?) will *warn* about -finline-functions, but still allow it. This
is very annoying, so check for that warning, too.
Per discussion on devel
(http://www.open-mpi.org/community/lists/devel/2015/02/17030.php), and
per Autoconf 2.69 docs, use the recommended AC_SEARCH_LIBS instead of
AC_CHECK_LIB (e.g., for functions that appear in libc on some
platforms and in a specific library on other platforms).
Use of this configuration option can cause crashing, hanging, and
(worse) incorrect results when btl/sm, btl/scif, or btl/vader are
in use. We discussed this at the January 2015 developers meeting
and it was decided to remove the option entirely. This commit does
just that. All usage of OPAL_WANT_SMP_LOCKS has been removed.
Honestly, a bunch of this code could use similar treatment (i.e.,
AC_DEFUN a template that can be used for OPAL/ORTE/OMPI). However, I
don't quite have time for this today. Exercise left for the future reader...
The RPATH support added a @{libdir} token into
<package>_WRAPPER_EXTRA_LDFLAGS. However, these flags are also

pkg-config *does* understand.

Fixes#324
Before this commit we checked if the compiler supported compare-and-exchange
on 128-bit values. This turned out to be insufficient. This commit strengthens
the check to see if the processor supports the instruction (or built-in). This
check will not work when cross-compiling (will always disable the 128-bit
atomic) so overrides have been added for this case.
1. Ensure to override CFLAGS properly. Move the setting of CFLAGS outside the AM_CONDITIONAL so that Automake doesn't get confused (because CFLAGS is already set inside an AM_CONDITIONAL -- moving it outside the conditional ensure that this local CFLAGS override trumps all other CFLAGS overrides).
2. Only build libfabric on Linux. Add a little more configury to ensure that we only try to build libfabric on Linux.
3. Remove a dead/unused file
4. Fix typo in condition check
5. Use "false", not "/bin/false"
This commit represents the conversion of the usnic BTL from verbs to
libfabric.
For the moment, libfabric is embedded in Open MPI (currently in the
usnic BTL). This is because the libfabric API is still changing, and
also has not yet been released. Ultimately, this embedded copy of
libfabric will likely disappear and the usnic BTL will rely on an
external installation of libfabric.
New configure options:
* --with-libfabric: will cause configure to fail if libfabric support
cannot be built
* --without-libfabric: will prevent libfabric support from being built
* --with-libfabric=DIR: use an external libfabric installation
* --with-libfabric-libdir=LIBDIR: when paired with --with-libfabric=DIR,
use LIBDIR for the libfabric installation library dir
The --with-libnl3[-libdir] arguments are now gone.
Some versions of gcc require this flag to be set before the __sync
builtin atomic compare and swap will support 128-bit values. If the
flag is required this check adds the flag to the CFLAGS.
A 128-bit compare-and-swap will enable a better atomic lifo implementation
that uses the pointer + counter method to avoid ABA issues. This commit
adds configury to check for the instruction (cmpxchg16b) and adds an
implementation that uses the __int128 type available in C99.
Clean up the orte_check_alps.m4. There was a little of

Change the CPPFLAGS to just -I$srcdir, and change the include file to
check to be just opal/libltdl/ltdl.h. Do this because the CPPFLAGS
are passed to the preprocessor, and the C program that is passed

#include <opal/libltdl/ltdl.h>
Using the proper -I covers both VPATH and non-VPATH cases.
The mixing of the Slurm PMI and Cray PMI configure was getting
messy and dangerous - developers working on Slurm PMI often don't
have access to Cray PMI, etc.
This mod pulls out the Cray PMI configure into a separate m4 file.
Cray pmi is now configured as follows:
1) on Cray CLE 5 and higher, Cray PMI is auto detected. pkg-config
is used to resolve the necessary CPP flags, link flags and libs,
etc. Nothing needs to be added to the configure line to pick up
Cray PMI.
2) on legacy Cray CLE 4 systems with PMI 4.X, Cray PMI is also
auto detected.
3) on legacy Cray CLE 4 systems with PMI 5.X Cray PMI can't be auto-detected
owing to changes in the PMI pkg-config file which result in pkg-config
returning an error owing to a dependency of PMI on newer versions of ALPS
installs that are not present on CLE 4. So, for those falling in to this
situation, the --with-cray-pmi=(DIR) method needs to be used.
DIR specifies the Cray PMI install directory. The configure file looks
for required alps libraries first in /usr/lib/alps, then in
/opt/cray/xe-sysroot/default/usr/lib/alps.
In OMPI 1.8 and 1.8.1, we didn't allow gfortran to use the ignore-TKR
style "mpi" Fortran module (which is written in Fortran). Instead,
gfortran used the TKR style "mpi" module, which is written in C.
In OMPI 1.8.2, we removed the gfortran restriction (for suitably
modern gfortran -- i.e., >= 4.9). This allowed gfortran to use the
ignore-TKR style "mpi" module, but exposed a bug where MPI Fortran
sentinel values wouldn't be linked properly on OS X. The solution is
to use ```-Wl,-flat_namespace``` (see the OS X ld(1) man page for
details) when both building the libraries and in the wrapper
compilers.

Fixes#257
There is a continued interest in being able to do static
linking of executables. When using pkg-config to determine
linking requirements, the default behavior is to only
specify libraries required for dynamic linking.
In many cases, it suffices even for static linking to
use
pkg-config --libs package
to obtain the linkage string required for ld. However, for
libraries that have dependencies on non-standard libraries,
this may not be the case. The cray PMI library is such a case.
On a Cray CLE 5.X system, for example
pkg-config --libs cray-pmi
returns a string like
-L/opt/cray/pmi/5.0.2-1.0000.9906.117.2.ari/lib64 -lpmi
whereas
pkgconfig --static --libs cray-pmi
returns a string (modified for git commits) like
-L/opt/cray/pmi/5.0.2-1.0000.9906.117.2.ari/lib64
-L/opt/cray/ugni/5.0-1.0000.8563.255.10.ari/lib64

Unfortunately the pkg.m4 does not contain a function for adding
the --static option to PKG_CHECK_MODULES. This commit defines
a new function, PKG_CHECK_MODULES_STATIC, which in addition to
defining the $1_CFLAGS and $1_LIBS variables defined by PKG_CHECK_MODULES,
also defines a $1_STATIC_LIBS.
We must also set the static library filenames properly (i.e., obey the
$FRAMEWORK_LIB_PREFIX that was set). Hence, set the prefixes earlier
in configure.ac, and update OPAL_MCA to set the static library names
properly.
These two macros set the MCA prefix and MCA cmd line id,
respectively. Specifically, MCA parameters will be named
PREFIX<foo> in the environment, and the cmd line will use
-ID foo bar.
These macros must be called during configure.ac and a value
supplied. In the case of Open MPI, the values given are
PREFIX=OMPI_MCA_ and ID=mca.
Other projects (such as ORCM) will call these macros with
their own unique values. For example, ORCM uses PREFIX=ORCM_MCA_
and ID=omca
This scheme is necessary to allow running Open MPI applications under
systems that use their own versions of ORTE and OPAL. For example,
when running OMPI applications under ORCM, we need the MCA params passed
to the ORCM daemons to be separated from those recognized by the OMPI application.
These two macros set the prefix for the OPAL and ORTE libraries,
respectively. Specifically, the OPAL library will be named
libPREFIXopen-pal.la and the ORTE library will be named
libPREFIXopen-rte.la.
These macros must be called, even if the prefix argument is empty.
The intent is that Open MPI will call these macros with an empty
prefix, but other projects (such as ORCM) will call these macros with
a non-empty prefix. For example, ORCM libraries can be named
liborcm-open-pal.la and liborcm-open-rte.la.
This scheme is necessary to allow running Open MPI applications under
systems that use their own versions of ORTE and OPAL. For example,
when running MPI applications under ORTE, if the ORTE and OPAL
libraries between OMPI and ORCM are not identical (which, because they
are released at different times, are likely to be different), we need
to ensure that the OMPI applications link against their ORTE and OPAL
libraries, but the ORCM executables link against their ORTE and OPAL
libraries.
This commit makes the folowing changes:
- Add support for the knem single-copy mechanism. Initially vader will only
support the synchronous copy mode. Asynchronous copy support may be added
int the future.
- Improve Linux cross memory attach (CMA) when using restrictive ptrace
settings. This will allow Open MPI to use CMA without modifying the system
settings to support ptrace attach (see /etc/sysctl.d/10-ptrace.conf).
- Allow runtime selection of the single copy mechanism. The default behavior
is to use the best available. The priority list of single-copy mehanisms is
as follows: xpmem, cma, and knem.
- Allow disabling support for kernel-assisted single copy.
- Some tuning and bug fixes.
Update the VERSION file scheme:
* Remove "want_repo_rev".
* Add "tarball_version".
All values are now always included (major, minor, release, greek,
repo_rev). However, configure.ac now runs "opal_get_version.sh
... --tarball", which will return the value of tarball_version (if it
is non-empty) or the "full" version string (i.e.,
"major.minor.releasegreek").
Remove configure.params support: configure.params hasn't been used in
years.
Also remove autogen.subdirs support; those should really be handled by
their respective Makefile.am's.
This is a first cut at updating various infrastructure for git. There
will definitely be more commits; some of the scripts require
committed/pushed code (e.g., the various make-tarball scripts). So
it's not possible to know if we got it right without committing/pushing.
In all previous releases, the version number would be "A.B.C" unless C
was 0, in which case it would be "A.B". This commit changes that
scheme to always be "A.B.C", even if C==0.
Hence, v1.9.0 will be the first release where this new scheme is evident.

This commit was SVN r32772.
What started as a simple ticket ended up reaching the way up to the
MPI Forum.
It turns out that we are supposed to have MPI_SIZEOF for all Fortran
interfaces: mpif.h, the mpi module, and the mpi_f08 module.
It further turns out that to properly support MPI_SIZEOF, your Fortran
compiler *has* support the INTERFACE keyword and ISO_FORTRAN_ENV. We
can't use "ignore TKR" functionality, because the whole point of
MPI_SIZEOF is that the implementation knows what type was passed to it
("ignore TKR" functionality, by definition, throws that information
away). Hence, we have to have an MPI_SIZEOF interface+implementation
for all intrinsic types, kinds, and ranks.
This commit therefore adds a perl script that generates both the
interfaces and implementations for MPI_SIZEOF in each of mpif.h, the
mpi module, and mpi_f08 module (yay consolidation!).
The perl script uses the results of some new configure tests:
* check if the Fortran compiler supports the INTERFACE keyword
* check if the Fortran compiler supports ISO_FORTRAN_ENV
* find the max array rank (i.e., dimension) that the compiler supports
If the Fortran compiler supports both INTERFACE and ISO_FORTRAN_ENV,
then we'll build the MPI_SIZEOF interfaces. If not, we'll skip
MPI_SIZEOF in mpif.h and the mpi module. Note that we won't build the
mpi_f08 module -- to include the MPI_SIZEOF interfaces -- if the
Fortran compiler doesn't support INTERFACE, ISO_FORTRAN_ENV, and a
whole bunch of ther modern Fortran stuff.
Since MPI_SIZEOF interfaces are now generated by the perl script, this
commit also removes all the old MPI_SIZEOF implementations (which were
laden with a zillion #if blocks).
cmr=v1.8.3
This commit was SVN r32764.
After discussions with Craig, it looks like the check in this
configure test was too aggressive and based on a prior mpi_f08
implementation model. We don't use "value" any more, and we also
don't pass optional parameters back to C code, so this test was
checking far more than it needed to... in a non-standard way (which
breaks in the Intel 2015 Fortran compiler). All we ''really'' need is
to check whether the compiler supports the "optional" keyword. So
make the test ''much'' simpler and just check whether ''optional''
compiles successfull or not.

Ticket 4868 --> https://svn.open-mpi.org/trac/ompi/ticket/4868
WHAT: Merge the PMIx branch into the devel repo, creating a new
OPAL “lmix” framework to abstract PMI support for all RTEs.
Replace the ORTE daemon-level collectives with a new PMIx
server and update the ORTE grpcomm framework to support
server-to-server collectives
WHY: We’ve had problems dealing with variations in PMI implementations,
and need to extend the existing PMI definitions to meet exascale
requirements.
WHEN: Mon, Aug 25
WHERE: https://github.com/rhc54/ompi-svn-mirror.git
Several community members have been working on a refactoring of the current PMI support within OMPI. Although the APIs are common, Slurm and Cray implement a different range of capabilities, and package them differently. For example, Cray provides an integrated PMI-1/2 library, while Slurm separates the two and requires the user to specify the one to be used at runtime. In addition, several bugs in the Slurm implementations have caused problems requiring extra coding.
All this has led to a slew of #if’s in the PMI code and bugs when the corner-case logic for one implementation accidentally traps the other. Extending this support to other implementations would have increased this complexity to an unacceptable level.
Accordingly, we have:
* created a new OPAL “pmix” framework to abstract the PMI support, with separate components for Cray, Slurm PMI-1, and Slurm PMI-2 implementations.
* Replaced the current ORTE grpcomm daemon-based collective operation with an integrated PMIx server, and updated the grpcomm APIs to provide more flexible, multi-algorithm support for collective operations. At this time, only the xcast and allgather operations are supported.
* Replaced the current global collective id with a signature based on the names of the participating procs. The allows an unlimited number of collectives to be executed by any group of processes, subject to the requirement that only one collective can be active at a time for a unique combination of procs. Note that a proc can be involved in any number of simultaneous collectives - it is the specific combination of procs that is subject to the constraint
* removed the prior OMPI/OPAL modex code
* added new macros for executing modex send/recv to simplify use of the new APIs. The send macros allow the caller to specify whether or not the BTL supports async modex operations - if so, then the non-blocking “fence” operation is used, if the active PMIx component supports it. Otherwise, the default is a full blocking modex exchange as we currently perform.
* retained the current flag that directs us to use a blocking fence operation, but only to retrieve data upon demand

In core library portions of the configury (e.g., top-level
configure.ac itself), we were calling AC_CHECK_LIB and
OPAL_CHECK_FUNC_LIB to check for various libraries.
'''SIDENOTE:''' It turns out that modern Autoconf has AC_SEARCH_LIBS,
which does just about exactly what OPAL_CHECK_FUNC_LIB does. So this
commit effectively replaces OPAL_CHECK_FUNC_LIB with AC_SEARCH_LIBS.
However, we never bothered to add these found libraries to the wrapper
compiler list of libraries used for static linking (doh!). We've been
getting lucky for quite a while that components were adding the same
libraries to their wrapper compiler LIBS list.
This is problematic, however, if we don't build some of these
components. For example, Paul Hargrove noticed that if he configured
with --disable-shared --enable-static --disable-io-romio, ROMIO was no
longer adding some libraries to the wrapper LIBS list -- libraries
that just happened to also be needed by core OPAL/ORTE/OMPI layers.
The solution is not to use AC_CHECK_LIB or OPAL_CHECK_FUNC_LIB, but
use a pair of new macros:
* OPAL_SEARCH_LIBS_CORE: a wrapper around AC_SEARCH_LIBS. If we add
something to $LIBS, then also add it to the wrapper list of static
libraries. This is the main piece of functionality that was
wrong/missing.
* OPAL_SEARCH_LIBS_COMPONENT: similar to OPAL_SEARCH_LIBS_CORE, but
instead of directly adding it to the wrapper list of static
libaries, add it to <framework>_<component>_LIBS (which eventually
gets slurped up into the wrapper list of static libraries. See the
lengthy comment in config/opal_setup_wrappers.m4 near the beginning
of OPAL_SETUP_WRAPPER_INIT() for a more detailed explanation).
Most components did this correctly already, but one or two weren't
right, so I implemented this second macro quite similar to the
first and put it everywhere we already used AC_SEARCH_LIBS or
OPAL_CHECK_FUNC_LIB.
This needs to soak for a day or two on the trunk before moving to the
v1.8 branch.

WHAT: Open our low-level communication infrastructure by moving all necessary components (btl/rcache/allocator/mpool) down in OPAL
All the components required for inter-process communications are currently deeply integrated in the OMPI layer. Several groups/institutions have express interest in having a more generic communication infrastructure, without all the OMPI layer dependencies. This communication layer should be made available at a different software level, available to all layers in the Open MPI software stack. As an example, our ORTE layer could replace the current OOB and instead use the BTL directly, gaining access to more reactive network interfaces than TCP. Similarly, external software libraries could take advantage of our highly optimized AM (active message) communication layer for their own purpose. UTK with support from Sandia, developped a version of Open MPI where the entire communication infrastucture has been moved down to OPAL (btl/rcache/allocator/mpool). Most of the moved components have been updated to match the new schema, with few exceptions (mainly BTLs where I have no way of compiling/testing them). Thus, the completion of this RFC is tied to being able to completing this move for all BTLs. For this we need help from the rest of the Open MPI community, especially those supporting some of the BTLs. A non-exhaustive list of BTLs that qualify here is: mx, portals4, scif, udapl, ugni, usnic.

ABSoft compilers cannot compile a fortran subroutine

cmr=v1.8.2:reviewer=jsquyres
This commit was SVN r32246.
Older gfortran compilers (e.g., the gfortran that ships in RHEL5) do
not support ISO_C_BINDING, and therefore do not support the
TYPE(C_PTR) type. As such, they cannot support the overloaded
interfaces for MPI_WIN_ALLOCATE_SHARED and MPI_SHARED_QUERY that are
mandated in MPI-3.
So we separate those interfaces out into a separate .F90 file that is
#include'd in the tkr mpi.F90 file. In this separate .F90 file, we
use an #if to determine whether the compiler supports ISO_C_BINDING or
not.
Also re-jiggered the order of testing in ompi_setup_mpi_fortran.m4: we
now need to test whether the compiler supports ISO_C_BINDING even when
we're only building the mpi module (not strictly when we're building
the mpi_f08 module).
Finally, tweaked the use-mpi-tkr/Makefile.am to:
* Add some proper dependencies for mpi.F90
* Allow the general AM compilation to be used instead of supplying a
specific rule for compiling mpi.F90

Clang 3.4 static analysis is now smart enough that it refuses to
compile our POSIX threading tests because we simply passed 0 for
several arguments (the test is checking for the linker presence of
symbols, so the NULL arguments didn't matter). Specifically, Clang's
anti-NULL compile-time checks now refuse to compile this bogus code.
Hence, these 2 configure test codes now have real variables and
pointers so that clang will compile it properly.
Without this fix, configure determines that there is no POSIX
threading support, and the osc/sm component fails to compile (which is
a different defect I'll be filing shortly). As such, we need this fix
in 1.8.1.
Also, change from the deprecated AC_TRY_LINK to AC_LINK_IFELSE.

This commit decouples OMPI deployment from the version(s) of the lower
layers of the stack by probing for UDP support.
Verbs applications assume a 40-byte header (there is no current
mechanism for querying payload offset). So to support a 42-byte UDP
header without causing existing applications like ibv_ud_pingpong or
older versions of OMPI to crash, we must inform libusnic_verbs that we
are aware of the nonstandard payload offset. We do this by overriding
the `transport_type` field of the device to be 42 before calling
`ibv_open_device`. If the library resets it to something else, then we
know the lower layers are UDP capable. Otherwise we use the older
custom-L2 format.
This necessitated some minor ugliness in common_verbs, but it's as tidy
as Jeff and I know how to make it right now.
This commit only adds support for UDP headers and connectivity over the
same L2 network, it does not touch routing or interface pairing.

Add a configure test to see if the Fortran compiler supports the

defined in configure-fortran-output-bottom.h).
This is needed to support the PGI 9 Fortran compiler, which does not
support the PROTECTED keyword.
Note that regardless of whether we want to support the PGI 9 Fortran
compiler + mpi_f08, we need to correctly detect whether PROTECTED
works or not, and then use that determination as a criteria for
building the mpi_f08 module. Previously, mpi-f08-types.F90 used
PROTECTED unconditionally, and we didn't test for it in configure. So
if a compiler (e.g., PGI 9) supported everything else but didn't
support PROTECTED, it would try to compile the mpi_f08 stuff and choke
on the use of PROTECTED.

This configure option was only relevant when we were generating TKR
"use mpi" interfaces for MPI subroutines with choice buffers. Now
that we aren't, the only interface that needs to accept a choice
buffer is MPI_SIZEOF (which we have to provide).
And since there's now only several dozen interfaces in the "mpi" TKR
module, there's no reason to not generate ''all'' possible array rank
values (when there were thousands of interfaces, generating 4-vs-7
array ranks per interface per type was a big deal). The default used
to be 4; now we can just hard-code it to 7, the max possible value for
Fortran 2003 (I think the max was raised ?to 11? in F2008, but let's
not go there for now).

8 years and it has performance issues we'll never be able to
overcome. Note that we have plans for re-adding async progress, using
a hybrid protocol of async and sync sends.
- OMPI_ENABLE_THREAD_MULTIPLE now determines whether the thread lock
macros do the check or not.
- Condition variables are ALWAYS polling right now, which fixes the thread
live-lock currently found when THREAD_MULTIPLE is turned on.

http://www.open-mpi.org/community/lists/users/2013/10/22882.php, fix
the value of MPI_STATUS_SIZE for the -i8 case. Thanks to Jim Parker
for bringing up the issue and providing the patch.
Separate patches are required for v1.6 and v1.7 (and will be attached
to their respective tickets), because this breaks ABI, so we need a
non-default configure option to fix the issue but knowingly break ABI.

r29830 -- Jeff will straighten this out with Alexander in person next
week (I can't test this myself because I have no access to libhcoll).
Sorry for the hassle...

it from the OPAL_VAR_SCOPE, so it should be fixed now.
Sorry about that, folks! :-(
