Jeff,
I tried building 1.7.1 on my Ubuntu system. The default gfortran is
v4.6.3, so configure won't enable the mpi_f08 module build. I also
tried a three week old snapshot of the gfortran 4.9 trunk. This has
Tobias's new TYPE(*) in it, but not his latest !GCC$ attributes
NO_ARG_CHECK stuff. However configure still won't enable the mpi_f08
module.
Is there a trick to getting a recent gfortran to compile the mpi_f08 module?
I went into the openmpi-1.7.1/ompi/mpi/fortran/use-mpi-tkr/scripts
directory and modified the files to use ierror instead of ierr. (One
well-crafted line of shell script.) Did the same with a couple of .h.in
files in the use-mpi-tkr and use-mpi-ignore-tkr directories, and
use-mpi-tkr/attr_fn-f90-interfaces.h.in. (One editor command each.)
With the above, the mpi module is in much better shape. However there
are still some scattered incorrect non-ierror argument names. A few
examples from the code I am working with:
MPI_Type_create_struct: The 2nd argument should be
"array_of_blocklengths", instead of "array_of_block_lengths"
MPI_Type_commit: "datatype" instead of "type"
MPI_Type_free: Again, "datatype" instead of "type"
There are more...

Hi Jeff,
I just downloaded 1.7.1. The new files in the use-mpi-f08 look great!
However the use-mpi-tkr and use-mpi-ignore-tkr directories don't fare so
well. Literally all the interfaces are still 'ierr'.
While I realize that both the F90 mpi module and interface checking,
were optional prior to MPI 3.0, the final argument has been called
'ierror' since MPI 1! This really should be fixed.

Can you try v1.7.1?
We did a major Fortran revamp in the 1.7.x series to bring it up to
speed with MPI-3 Fortran stuff (at least mostly). I mention MPI-3
because the name-based parameter passing stuff wasn't guaranteed until
MPI-3. I think 1.7.x should have gotten all the name-based parameter
passing stuff correct (please let me know if you find any bugs!).
Just to be clear: it is unlikely that we'll be updating the Fortran
support in the 1.6.x series.

Hi,
The MPI Standard specifies to use 'ierror' for the final argument in
most Fortran MPI calls. However the Openmpi f90 module defines it as
being 'ierr'. This messes up those who want to use keyword=value
syntax in their calls.
I just checked the latest 1.6.4 release and it is still broken.
Is this something that can be fixed?
