The g95 compiler supports both a G95_UNBUFFERED_ALL and
a set of G95_UNBUFFERED_# environmentals to unbuffer
specific io devices. I know we have GFORTRAN_UNBUFFERED_ALL
in gfortran but do we also have the matching GFORTRAN_UNBUFFERED_#
environmentals as well? If not, that would be a worthwhile
addition to gfortran.
