[Bug fortran/33795] New: Environment variable GFORTRAN_UNBUFFERED_<number> not working

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

As found by Harald Anlauf, http://gcc.gnu.org/ml/fortran/2007-10/msg00239.html
,
the GFORTRAN_UNBUFFERED_<number> environment variables are not effective, only
GFORTRAN_UNBUFFERED_ALL affects the buffering.

Francois-Xavier replied:

Currently, GFORTRAN_UNBUFFERED_ALL is implemented but
GFORTRAN_UNBUFFERED_n (where n is not ALL) isn't. This should either
be implemented, or the documentation for that feature should be
removed (as well as the unused code providing  partial support for
it). I think the second choice is simplest, because 1. people who want
unbuffered output can use GFORTRAN_UNBUFFERED_ALL, and 2. if they
really need partial unbuffered output, they can use FLUSH.
