-# Whether to build the OpenShmem fortran support or not For the
-# moment, use the same value as was derived from --enable-mpi-fortra.
-# *This seems wrong*; someone should somehow unify these two
-# options... but the implications are complicated.
 #
-# Option 1: make --enable-fortran that governs both MPI and shmem.
-# This has 2 implications:
-# - --enable-mpi-fortran needs to be maintained for at least the
-#   1.7/1.8 series
-# - what to do with --enable-mpi-cxx?  It should be made consistent --
-#   so make it --enable-cxx?
-# 
-# Option 2: make separate --enable-oshmem-fortran.  This seems sucky,
-# though, because oshmem Fortran depends on a lot of MPI Fortran
-# infrastructure.  If it isin't there, then oshmem Fortran can't
-# built.
