# THIS MAKEFILE IS OLD AND ONLY TO SUPPORT FORTRAN COMPILERS THAT DO
# NOT SUPPORT "IGNORE TKR" FUNCTIONALITY (i.e., gfortran before v4.9).
# All other Fortran compilers support ignore TKR and don't compile
# this directory -- instead, they compile
# ompi/fortran/use-mpi-ignore-tkr.

# Note that Automake's Fortran-buidling rules uses CPPFLAGS and
# AM_CPPFLAGS.  This can cause weirdness (e.g.,
# https://github.com/open-mpi/ompi/issues/7253).  Let's just zero
# those out and rely on AM_FCFLAGS.
