1. Canary compile-time test: this is compiled whenever you compile
the entire OMPI tree. It's a noinst standalone library comprised
of a single .c file, so no one will notice its addition, and it
doesn't get linked/installed to any real build products. If we
are out of padding space on any predefined MPI object type, it
will fail to compile. This will alert/annoy a human, who will be
able to fix the real problem.
1. Added a "make check" test that will print out the amount of
predefined padding left on all the MPI object types.
This commit was SVN r30268.
