#  Tested with gcc-gfortran v4.0.x as shipped with Fedora Core 4.
#  It fixes the ' \' versus ' &' terminator problem but some 
#  namelist problems remain.  The biggest seems to be the inability
#  of current gfortran versions to support namelist syntax such as:
#
#     fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ',
#
#  which results in run-time errors.
