#  Tested with gcc-gfortran v4.1.1 on FC5, FC6, FC8, using flags
#              formally for gcc-gfortran 4.3*
#       + with gcc-gfortran v4.3.0 on FC9
#  It fixes the ' \' versus ' &' terminator problem ;
#  some namelist problems remain with old version (The biggest seems 
#     to be the inability to support namelist syntax such as:
#     fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ',
#      which results in run-time errors).
