program main

!
! This program makes use of a common (but not universal; g77 doesn't
! have it) extension: the "Cray" pointer. This allows MPI_Alloc_mem
! to allocate memory and return it to Fortran, where it can be used.
! As this is not standard Fortran, this test is not run by default.
! To run it, build (with a suitable compiler) and run with
! mpiexec -n 1 ./allocmemf
