I copied the config directory in another location, and the original
.svn directory was replaced by the Open MPI one ... As a result my
first commit, applied the changes on the Open MPI trunk instead of
the other project.

MPI::ERRORS_THROW_EXCEPTIONS with gcc in 32 bit (but not 64 bit!).
* Ensure that the C and Fortran compilers actually like the C++
exceptions flags. If not, currently just abort. Let's see if
anyone complains about this -- I doubt they will because a) C++
exception support is not enabled by default, and b) I think C++
exceptions really only make sense within the same compiler family.

which may source a "noisy" `~/.whatever` file, and we do not want the
error messages to be part of the assignment in {{{foo=`which

* Check that the C++, Fortran 77, and Objective C comilers emit code
that can link against object files emitted by the C compiler.
Moves some built / run time errors to configure time, which is
nice and should help with the debugging
* Remove unneeded -F option when building the XGrid components,
which started causing problems with LT 2.0.
* Try to use the XGridFoundation library, rather than just seeing
if we can give -framework XGridFoundation. Should make the
test slightly more accurate
* Don't assume XGrid is unavailable on 64 bit platforms, as that
won't be true on Leopard
* Require AM 1.10 or newer if using AC 2.60 or newer, so that
we don't have a split of AC supporting Objective C and AM

just think these were functions and we wouldn't get the error, because
we didn't try to link.

before checking if we are able to compile the test program. This is required
for windows as the C++ conftest.c file generated by configure cannot be
compiled with the Microsoft cl.exe compiler (because of the exit function
prototype). So if we detect a vendor equal to microsoft we will assume
that the compiler is correctly installed (which is true on Windows most
of the time anyway).

to such casts, fall back to a standard C-style cast.

We have repeatedly seen users inadvertantly try to use a C compiler
for $CXX (e.g., using icc instead of icpc in recent versions of the
Intel compiler). Unfortunately, this would "sorta work", meaning that
configure would complete successfully and the build would fail much
later in the process (when $CXX was used to try to link a C++
compiler). This was further compounded by the fact that many C
compilers will switch into "C++ mode" when they compile files that end
in .cc -- meaning that they'll *compile* C++ codes properly, but they
won't *link* properly. Hence, users would get all the way down to
compiling the C++ MPI bindings or ompi_info (i.e., very late in the
build process) before the problem became evident.
We already have a test in configure that tries to compile, link, and
run a sample C++ program. This helped ensure that $CXX was a valid
compiler, but it did not catch if the user accidentally supplied a C
compiler instead of a C++ compiler because the test program was simply
"return 0". This commit updates the test program to use some
C++-specific constructs (std::string) so that if the user supplies a C
compiler in $CXX, the program may *compile*, but it will definitely
fail to *link*.
Hence, the process will fail early in configure (with a descriptive
message about how the compiler failed to work properly) rather than
late in the build.
