Compilation fails for mod_mpi_buffer_client (XMLIO_SERVER)

[ufla]

Not sure if this is the best place to file XMLIO_SERVER bugs, however:

The file mod_mpi_buffer_client.F90 (EXTERNAL/XMLIO_SERVER/src/IOSERVER) fails to compile because it's USEing a module 'mpi', which does not exist if one is not using a F90 MPI implementation. I suspect that the module sought is 'mpi_mod'. At least, things compile and seem to work with that change.

This bug still prevents me from compiling (without modifying the sources). Could somebody confirm this? Here's a diff:

I'm not having any trouble with this code straight from the trunk. MPI_STATUS_SIZE is a mpi parameter that will be defined in the mpi.mod that should come with the system installation of MPI. 

mpi_mod.f90 uses an old-fashioned, 'INCLUDE' statement to include mpif.h (which should also come with the system). mpif.h contains the same settings as mpi.mod but is F77-style. 

It would seem that either your system installation hasn't built mpi.mod or the compiler isn't looking in the correct place. The majority of systems with full f90 support shouldn't require this code change but the rest of the model still uses "INCLUDE 'mpif.h'" (i.e. lib_mpp.F90, mpp_map.F90 and obs_mpp.F90) so there is a argument for making the change on the grounds of consistency.
