Dear MPICH maintainers, when I try to compile my Fortran application in strict 2008 standard and include mpif.h, I'll get an error or a warning from both, the GNU and the Intel Fortran compiler, complaining about the declaration of some datatypes When invoking gfortran with -std=f2008ts, the complaints are: Error: GNU Extension: Nonstandard type declaration INTEGER*8 at (1) Warning: Obsolescent feature: Old-style character length at (1) and for ifort with -stand f08, I'll get : warning #6916: Fortran 2008 does not allow this length specification. [8] The CHARACTER* form of a CHARACTER declaration is an obsolescent feature in Fortran 2008. According to http://fortranwiki.org/fortran/show/Modernizing+Old +Fortran, this can be solved by the following changes in mpif.h and mpiof.h: diff mpif.h mpif.h_new 16,17c16,17 < CHARACTER*1 MPI_ARGVS_NULL(1,1) < CHARACTER*1 MPI_ARGV_NULL(1) ---

CHARACTER(len=1) MPI_ARGVS_NULL(1,1) CHARACTER(len=1) MPI_ARGV_NULL(1)

528c528 < integer*8 MPI_DISPLACEMENT_CURRENT ---

integer(kind=8) MPI_DISPLACEMENT_CURRENT

546,547c546,547 < REAL*8 MPI_WTIME, MPI_WTICK < REAL*8 PMPI_WTIME, PMPI_WTICK ---

REAL(kind=8) MPI_WTIME, MPI_WTICK REAL(kind=8) PMPI_WTIME, PMPI_WTICK

diff mpiof.h mpiof.h_new 29c29 < integer*8 MPI_DISPLACEMENT_CURRENT ---

integer(kind=8) MPI_DISPLACEMENT_CURRENT
