following for the rationale:

Note that mpi.h only receives AC_DEFINE's (not AC_SUBST's), so we
still have to AC_DEFINE to get the value in there -- so we AC_DEFINE
something that we give to a typedef.

the page address three situations:
1. if the array of requests are all REQUEST_NULL, set flag=true and
index=MPI_UNDEFINED
2. if the array of requests are not all REQUEST_NULL, if any of them
finished, set flag=true and index=whatever_the_index_was
3. if the array of requests are not all REQUEST_NULL, if none of them
finished, set flag=false and index=MPI_UNDEFINED
With regards to the index value, we are currently doing 1 and 2, but
not 3. More specifically, index should be set to MPI_UNDEFINED if no
requests are found to have completed (regardless of whether they are
REQUEST_NULL or not).
This patch fixes this problem.

functionality. This is a global registration, so all components have to be made
aware of the registration -- therefore, do things at the component level, not the
module level.

features. Now it works with gfortran as well.
The problem was that the cast between LOGICAL and INTEGER is not a Fortran language feature. The easiest solution around this problem is to have a C function that print the value. We set the value in fortran and then call the C function to print it out.

- when eof is reached at orterun, send a 0 byte message to peer indicating eof
- on receipt of zero byte message - close corresponding file descriptor associated with the endpoint
- require setup ptys for stdin and stdout so that stdin can be closed independently of stdout

case of:
sizeof(MPI_Flogical) != sizeof (int)
and
Fortran value of .TRUE. != 1
as is often the case.
- Check in configure the value of .TRUE., the C-type coresponding to
logical and check, that fortran compiler does not do something strange
with arrays of logicals
- Convert all occurrences of logicals in the fortran wrappers, only
in case it is needed.
*Please note* Implementation of MPI_Cart_sub needed special treatment.
- Output these value in ompi_info -a
- Clean up the prototypes_mpi.h to just have a single definition and
thereby deleting the necessity for prototypes_pmpi.h
- configured, compiled and tested with F90-program, which uses
MPI_Cart_create and MPI_Cart_get:
linux ia32, gcc (no testing, as no f90)
linux ia32, gcc --disable-mpi-f77 --disable-mpi-f90 (had a bug there)
linux ia32, icc-8.1
linux opteron, gcc-3.3.5, pgcc, pathccx/pathf90 (tested just
pgi-compiler)
linux em64t, gcc, icc-8.1 (tested just icc)

increase the previous connection code was broken. It can take as much as 60 seconds to connect
64 processes. Now we do not create the connections when we add the procs but only when we send
them the first message. Now it take only 1.6 seconds to setup a 64 procs MPI job over MX (doing a 2 steps barrier in order to insure that we create all the connections).

displacement (for both the inter and intra-communicator version). The
displacements in scatterv are given in multiples of the sendtype.
This fix should probably make to v1.0.1 as well?

argument is defined to be
integer (KIND=MPI_ADDRESS_KIND)
we have to map that to an MPI_Aint in the f->c interface, else the
typecast back from the C to the Fortran interface will be wrong as well.
The same holds (at least) for all other new MPI-2 datatype functions
which take a byte-displacement or an address as an argument.
