7  #  Tested with gcc-gfortran v4.0.x as shipped with Fedora Core 4.  #  Tested with gcc-gfortran v4.1.1 on FC5, FC6, FC8, using flags
8  #  It fixes the ' \' versus ' &' terminator problem but some  #              formally for gcc-gfortran 4.3*
9  #  namelist problems remain.  The biggest seems to be the inability  #       + with gcc-gfortran v4.3.0 on FC9
10  #  of current gfortran versions to support namelist syntax such as:  
11  #  #-------
12  #     fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ',  # run with OpenMP: needs to set environment var. OMP_NUM_THREADS
13  #  #    and generally, needs to increase the thread stack-size:
14  #  which results in run-time errors.  #   -  sh,bash:
15    #     > export OMP_NUM_THREADS=2
16    #     > export GOMP_STACKSIZE=400m
17    #   - csh,tcsh:
18    #     > setenv OMP_NUM_THREADS 2
