[svn-r5243]
Purpose:
Bug fix
Description:
Different MPI implementations use different ways to
pass MPI objects between C and Fortran layers. MPI-2 defines
a standard set of MPI_*_c2f(f2c) functions for this purpose.
Unfortunately it is not implemented everywhere and makes
code non-portable between different parallel platforms.
Solution:
Always use MPI_*c2f(f2c) functions in our code. Configure
finds out if those functions are available. If not, then we define
macros to immulate those functions.
Platforms tested:
IRIX64-6.5 (modi4) and SP3 (seaborg.nersc.gov). On those platforms
functions do not exist and we use macros. Bill will test on
HPUX System V (SDSC machine) to check if this works when functions
are defined. Preliminary testing showed that it worked.
