In ice_comp_mct.F90, lnd_comp_mct.F90, and rof_comp_mct.F90, there is a Fortran WRITE statement with an extraneous comma.

write(logunit,*), '...'
This statement is not valid according to the Fortran standard. While gfortran accepts it without error,
other compilers, such as the Cray ftn compiler on Frontier, report it as a compilation error.
