* Document --disable-mpi-cxx-seek
* Document that you need to include "mpi.h" after system-level
headers that create the SEEK_* constants
* Make the C++ examples follow this behavior (include "mpi.h" after
<iostream>)

Add --enable-orterun-prefix-by-default (and a synonym:
--enable-mpirun-prefix-by-default) to make orterun always behave as if
"--prefix $prefix" was given on the command line (where $prefix is the
value given to the --prefix option to configure). This prevents many
rsh/ssh users from needing to modify their shell startup files to set
the LD_LIBRARY_PATH for Open MPI (they will still need to set PATH or
otherwise find the OMPI executables to mpicc/mpirun/etc. their MPI
applications).
Also added --noprefix option to orterun to disable this behavior.
Finally, note that even if --enable-orterun-prefix-by-default is
specified, if the user specifies --prefix or /path/to/mpirun, these
options will override the default value of the prefix ($prefix).

compiler, automatically disable the ptmalloc component. It seems that
optimization level -O2 or higher will cause the generated code to do
Bad Things (e.g., opalcc will segv). Upgrading to the Intel 9.1
compiler seems to fix the problem.
This closes ticket #227.

mpi_leave_pinned when multiple OpenIB HCA ports are found.
Specifically, if mpi_leave_pinned == 1 and ultiple HCA ports are
found, the MCA parameter btl_openib_max_btls is set to 1. If the MCA
parameter btl_openib_warn_leave_pinned_multi_port is true, emit a
warning that this happened (having an MCA parameter to control the
warning allows users/sysadmins to turn it off instead of being nagged
for every run).

on platforms without a 32-bit compare and swap implementation. There isn't
such a thing on Sparc v8 chips, so we can't support those platforms right
now. Should be possible to make opal_atomic_lifo less atomic on these
platforms, but not in the time allotted.

Thanks to Anthony Chan for pointing this out.
Note that these will only work for the Fortran compiler that Open MPI
was configured with -- since these values, are, by definition,
single-value, they cannot support all 4 values that Open MPI may
generate for the different Fortran name-mangling schemes. A lengthy
comment in ompi_mpi_init.c explains this in more detail. Added to the
README to explain this situation, as well as the forthcoming
.TRUE. Fortran fixes.

new config.guess/config.sub files (!), but a) the code is smart enough
to know this, and b) when they become available again, the Right
Things will happen.
Also, I left the example code in there how to add man pages to the
relevant Makefile's on the thought that we'll need it when we
eventually get around to making man pages (assumedly through
doxygen).
