Yet another forgotten issue regarding the f90 large interfaces
(note that MPI_IN_PLACE is currently an integer, for a time it was a
double complex but that has been fixed).
Problem I have now is that my patches which worked with 1.2 don't
work with 1.3. I've tried various fixes for my patches and I don't
have a solution like I have for MPI_Gather.
Error: Generic subroutine 'mpi_reduce' at (1) is not consistent with
a specific subroutine interface
sumpfi is an integer array, sumpfmi is an integer.
The problem is that MPI_IN_PLACE is an integer, so you can only
compile with the large interface file when the second argument of
MPI_REDUCE is an integer, not an integer array, or a character, or a
So this doubles the number of f90 interfaces needed for MPI_REDUCE
(and anything else that uses MPI_IN_PLACE).
